p.000030: By definition, HIV prevention research must follow the epidemic. In order to test if a biomedical HIV prevention
p.000030: intervention works, large numbers of individuals at high risk for HIV infection must be recruited for clinical trials.
p.000030: Sites based in communities with mature HIV epidemics have lower incidence rates and may be most appropriate for safety
p.000030: studies. Sites in communities with younger epidemics may be better suited for efficacy trials. However, partici- pating
p.000030: communities and populations, particularly for large-scale efficacy trials, will generally be characterized by
p.000030: multiple vulnera- bilities. The same factors that put these individuals at higher risk for exposure to HIV also make
p.000030: them vulnerable to cultural exclusion, social inequality, economic exploitation, and political oppression. Examples of
p.000030: populations that may have an increased vulnerability include women, children and adolescents, men who have sex with
p.000030: men, injecting drug users, sex workers, transgender persons, indig- enous populations, the poor, the homeless, and
p.000030: communities from resource-poor settings in high-income and low- and middle-income countries. At the same time, it is
p.000030: precisely these populations who stand to benefit most from the successful development of a new biomedical HIV
p.000030: prevention product or method. For these reasons, it is imperative to ensure protection of the rights of participants

p.000031:
p.000031: Decision-making around conducting a biomedical HIV prevention trial needs to consider in what ways the trial might
p.000031: increase or decrease vulnerabilities. On the one hand, a trial might increase a participant’s risk of exposure to
p.000031: stigmatisation and discrimination if it highlights a population’s increased vulnerability to HIV exposure. On the
p.000031: other hand, a trial might decrease vulnerability, if it empowers the community or provides tangible assistance to
p.000031: participants, for example by improving the accessibility, affordability, and quality of appropriate healthcare
p.000031: services in the community. A social and political analysis should be carried out early on in planning the research
p.000031: process, to assess determi- nants of vulnerability, such as poverty, gender, age, ethnicity, sexuality, health,
p.000031: employment, education, and legal conditions in potential partic- ipating communities. Findings from this analysis
p.000031: should inform the design of research protocols, which should be sensitive to emerging information on incidental risks
p.000031: of social harm throughout the course of a trial. Research protocols might also include ongoing independent monitoring
p.000031: of a trial in relation to its impact on the vulnerabilities of communities participating in the study (see Guidance
p.000031: Point 17).
p.000031: The particular aspects of a social context that create conditions for exploi- tation or increased vulnerability should
p.000031: be described in the research protocol, as should the safeguards and measures that will be taken to prevent and overcome

p.000002: used in the experimental and control arms are ethically justifiable.

p.000002: In order to conduct biomedical HIV prevention trials in an ethically acceptable manner, participation of individuals

p.000002: of the scientific goals of the research.
p.000002: Guidance Point 8: Vulnerable Populations
p.000002: The research protocol should describe the social contexts of a proposed research population (country or community) that

p.000002: Researchers and trial sponsors should recruit women into clinical trials in order to verify safety and efficacy from
p.000002: their standpoint, including immunogenicity in the case of vaccine trials, since women throughout the life span,
p.000002: including those who may become pregnant, be pregnant or be breastfeeding, should be recipients of future safe and
p.000002: effective biomedical HIV prevention interventions. During such research, women should receive adequate information to
p.000002: make informed choices about risks to themselves, as well as to their foetus or breastfed infant, where applicable.

p.000008: For many countries, AIDS is the leading cause of death. Currently available treatments do not lead to cure, but
p.000008: do slow the progression of disease.The most effective treatment for slowing HIV-related disease progression,
p.000008: antiretroviral medication, is a life-long treatment which requires close medical monitoring, is still very costly,
p.000008: especially for 2nd line regimens, and can cause significant adverse effects. Because of this, antiretroviral medi-
p.000008: cation is not readily available to the vast majority of people living with HIV who need it. More than 2 million people
p.000008: had access to antiretroviral treatments in low- and middle-income countries in 2006, five times more people than in
p.000008: 2003. But despite this tremendous progress in the roll-out of antiretroviral treatment, global coverage of needs is
p.000008: below 30%.
p.000008: For every person placed on antiretroviral treatment in 2006, another six people became newly infected with HIV. There
p.000008: is therefore an ethical imperative to seek, as urgently as possible, effective and accessible biomedical HIV prevention

p.000009: most vulnerable to exposure to HIV infection.
p.000009: Genetically distinct subtypes of HIV have been described, and different HIV subtypes are predominant in different
p.000009: regions and countries. The relevance of these sub-types to probabilities of HIV transmission and acquisition, speed of
p.000009: disease progression and potential protection is not clearly understood.
p.000009: For the conduct of efficacy trials of any biomedical HIV prevention product, the populations with the highest
p.000009: incidence of HIV will be those most likely to be considered for participa- tion and would be those most likely to
p.000009: benefit from an effective intervention. However, for a variety of reasons, these popula- tions may be relatively
p.000009: vulnerable to exploitation and harm in the context of biomedical HIV prevention trials.Trial sponsors, countries,
p.000009: researchers, research staff and community leaders must make additional efforts to overcome this vulnerability.
p.000009: In some biomedical HIV prevention trials, individuals other than the trial participants may experience risks if they
p.000009: are exposed to the experimental product and may experience benefits if the product is effective. For example in trials
p.000009: of prophylaxis of mother-to-child transmission, the foetus is exposed to the prophylactic antiretroviral regimen in
p.000009: addition to the mother. If the mother develops antiretroviral resistance, she may transmit resistant virus to the
p.000009: infant. When the intervention is effective, the newborn baby is protected. In trials of vaginal microbicides, male
p.000009: sexual partners may be exposed to the product even when condoms are used. In trials of successful vaccine candidates,
p.000009: not only sexual partners benefit but communities may benefit from population level effects.

p.000024: Clinical Trial Phases
p.000024:
p.000024: As phases I, II, and III in the clinical development of a biomedical HIV preventive intervention all have their
p.000024: own particular scientific requirements and specific ethical challenges, researchers and trial sponsors should justify
p.000024: in advance the choice of study populations for each trial phase, in scientific and ethical terms in all cases,
p.000024: regardless of where the study population is found. Generally, early clinical phases of biomedical HIV
p.000024: prevention research should be conducted in communities that are less vulnerable to harm or exploitation,
p.000024: usually within the sponsor country. However, countries may choose, for valid scientific and public health
p.000024: reasons, to conduct any trial phase within their populations, if they are able to ensure sufficient scientific
p.000024: infrastructure and sufficient ethical safeguards.
p.000024:
p.000024:
p.000024: The initial pre-clinical phase in the development of a biomedical HIV prevention product entails research in
p.000024: laboratories and among animals. The transition to a phase I clinical trial in which testing involves the
p.000024: administration of the product to human subjects to assess safety, and in the case of vaccines to assess immunogenicity,
p.000024: is a time when risks may not yet be well-defined. Hence, specific infrastructures are often required in order to ensure
p.000024: the safety and care of the research participants at these stages. For these reasons, the first administration of a
p.000024: candidate biomedical HIV prevention product in humans should generally be conducted in populations which are not at
p.000024: risk of HIV acquisition, usually in the country of the trial sponsor.
p.000024:
p.000024: Clinical trial researchers have been designing trials that fall somewhere between phase II (expanded safety and
p.000024: immunogenicity) and phase III (large scale trials to assess efficacy) – called phase IIB trials, or proof of concept
p.000024: trials. Phase IIB trials may provide an indication of

p.000025: UNAIDS / WHO guidance document
p.000025:
p.000025:
p.000025: an experimental candidate’s efficacy but are less costly in terms of money, time, and number of trial participants.
p.000025: However, such phase IIB trials are not designed to provide enough information for regula- tory approval at the end of
p.000025: the trial for an HIV prevention product subject to regulation; instead, these trials test the general concept of the
p.000025: candidate product and efficiently filter out products that lack efficacy. Eventually, a phase III trial would have to
p.000025: be conducted to develop a useable and licensable HIV product.
p.000025:
p.000025: There may be situations where low- and middle-income countries choose to conduct phases I/II and/or IIB and III
p.000025: among their populations that are relatively vulnerable to risk and exploitation. For instance, this could occur where
p.000025: an experimental HIV vaccine is directed primarily toward a viral strain that does not exist in the trial sponsor’s
p.000025: country but does exist in the country in which it is proposed the trial be conducted. Conducting phase I/II trials in
p.000025: the country where the strain exists may be the only way to determine whether safety and immunogenicity are acceptable
p.000025: in that particular population, prior to conducting a phase III trial. Another example might be a country that decides
p.000025: that, due to the high level of HIV risk to its population and the gravity of HIV prevalence in the country, it is
p.000025: willing to test a biomedical HIV prevention product concept that has not or is not being tested in another country.
p.000025: Such a decision may result in obvious benefits to the country in question if an effective product is eventually found.
p.000025: If phase I or phase II trials are conducted in the country intending to participate in an eventual phase III trial, if
p.000025: phases I and II are satisfactory, this may assist in building capacity for phase III trial conduct, including
p.000025: increasing levels of research literacy in the population.
p.000025:
p.000025: Establishing a biomedical HIV prevention product development programme that entails the conduct of some,
p.000025: most, or all of its clinical trial components in a country or community that is rela- tively vulnerable to harm or

p.000030: By definition, HIV prevention research must follow the epidemic. In order to test if a biomedical HIV prevention
p.000030: intervention works, large numbers of individuals at high risk for HIV infection must be recruited for clinical trials.
p.000030: Sites based in communities with mature HIV epidemics have lower incidence rates and may be most appropriate for safety
p.000030: studies. Sites in communities with younger epidemics may be better suited for efficacy trials. However, partici- pating
p.000030: communities and populations, particularly for large-scale efficacy trials, will generally be characterized by
p.000030: multiple vulnera- bilities. The same factors that put these individuals at higher risk for exposure to HIV also make
p.000030: them vulnerable to cultural exclusion, social inequality, economic exploitation, and political oppression. Examples of
p.000030: populations that may have an increased vulnerability include women, children and adolescents, men who have sex with
p.000030: men, injecting drug users, sex workers, transgender persons, indig- enous populations, the poor, the homeless, and

p.000057: All participants are entitled to confidentiality of information disclosed or discovered in the recruitment and informed

p.000057: There may be specific exceptions to the duty of confidentiality for legal or ethical reasons, but those exceptions
p.000057: should be prospectively identified and disclosed to the participant during the informed consent process.
p.000057: Legal exceptions to the duty to maintain confidentiality might exist, for example, where disclosure is mandated by a

p.000009: Genetically distinct subtypes of HIV have been described, and different HIV subtypes are predominant in different
p.000009: regions and countries. The relevance of these sub-types to probabilities of HIV transmission and acquisition, speed of
p.000009: disease progression and potential protection is not clearly understood.
p.000009: For the conduct of efficacy trials of any biomedical HIV prevention product, the populations with the highest
p.000009: incidence of HIV will be those most likely to be considered for participa- tion and would be those most likely to
p.000009: benefit from an effective intervention. However, for a variety of reasons, these popula- tions may be relatively
p.000009: vulnerable to exploitation and harm in the context of biomedical HIV prevention trials.Trial sponsors, countries,
p.000009: researchers, research staff and community leaders must make additional efforts to overcome this vulnerability.
p.000009: In some biomedical HIV prevention trials, individuals other than the trial participants may experience risks if they
p.000009: are exposed to the experimental product and may experience benefits if the product is effective. For example in trials
p.000009: of prophylaxis of mother-to-child transmission, the foetus is exposed to the prophylactic antiretroviral regimen in
p.000009: addition to the mother. If the mother develops antiretroviral resistance, she may transmit resistant virus to the
p.000009: infant. When the intervention is effective, the newborn baby is protected. In trials of vaginal microbicides, male
p.000009: sexual partners may be exposed to the product even when condoms are used. In trials of successful vaccine candidates,
p.000009: not only sexual partners benefit but communities may benefit from population level effects.

p.000010: additional safe and effective biomedical HIV prevention tools, in ethically accept- able manners, and their early
p.000010: distribution to populations most in need. Countries and communities considering participa- tion in biomedical HIV

p.000010: participation, based on their own health and human development priorities, in a context of equal collabora- tion with
p.000010: sponsors.
p.000010: HIV infection is both highly feared and stigmatised. This is in large part because it is associated with blood, death,
p.000010: sex, and activities which may not be legally sanctioned, such as commer- cial sex, men having sex with men, and illicit
p.000010: substance use. These are issues which are often difficult to address openly
p.000010: - at a societal and individual level. As a result, people living with HIV and those affected by AIDS may experience
p.000010: stigma, discrimination, and even violence; some communities continue to deny the existence and prevalence of HIV
p.000010: infection. Furthermore, vulnerability to HIV exposure and to the impact of AIDS is greater where people are
p.000010: marginalized due to their social, economic, and legal status. These factors increase the risk of social and
p.000010: psychological harm for people participating in biomedical HIV prevention trials. Additional efforts must be made to
p.000010: address these increased risks and to ensure that the risks participants take are justified by the anticipated benefits
p.000010: of the preventive intervention to the participants themselves or to others in the future.
p.000010: A key means by which to protect participants and the commu- nities from which they come is to ensure that the community
p.000010: in which the research is carried out is meaningfully involved in the design, implementation, monitoring, and
p.000010: dissemination of results of HIV prevention trials, including the involvement of representatives from marginalized

p.000030: By definition, HIV prevention research must follow the epidemic. In order to test if a biomedical HIV prevention
p.000030: intervention works, large numbers of individuals at high risk for HIV infection must be recruited for clinical trials.
p.000030: Sites based in communities with mature HIV epidemics have lower incidence rates and may be most appropriate for safety
p.000030: studies. Sites in communities with younger epidemics may be better suited for efficacy trials. However, partici- pating
p.000030: communities and populations, particularly for large-scale efficacy trials, will generally be characterized by
p.000030: multiple vulnera- bilities. The same factors that put these individuals at higher risk for exposure to HIV also make
p.000030: them vulnerable to cultural exclusion, social inequality, economic exploitation, and political oppression. Examples of
p.000030: populations that may have an increased vulnerability include women, children and adolescents, men who have sex with

p.000031: Decision-making around conducting a biomedical HIV prevention trial needs to consider in what ways the trial might
p.000031: increase or decrease vulnerabilities. On the one hand, a trial might increase a participant’s risk of exposure to
p.000031: stigmatisation and discrimination if it highlights a population’s increased vulnerability to HIV exposure. On the
p.000031: other hand, a trial might decrease vulnerability, if it empowers the community or provides tangible assistance to
p.000031: participants, for example by improving the accessibility, affordability, and quality of appropriate healthcare
p.000031: services in the community. A social and political analysis should be carried out early on in planning the research
p.000031: process, to assess determi- nants of vulnerability, such as poverty, gender, age, ethnicity, sexuality, health,
p.000031: employment, education, and legal conditions in potential partic- ipating communities. Findings from this analysis
p.000031: should inform the design of research protocols, which should be sensitive to emerging information on incidental risks
p.000031: of social harm throughout the course of a trial. Research protocols might also include ongoing independent monitoring
p.000031: of a trial in relation to its impact on the vulnerabilities of communities participating in the study (see Guidance
p.000031: Point 17).
p.000031: The particular aspects of a social context that create conditions for exploi- tation or increased vulnerability should
p.000031: be described in the research protocol, as should the safeguards and measures that will be taken to prevent and overcome
p.000031: them. In some potential research populations (countries or communities), conditions affecting potential vulnerability
p.000031: or exploitation may be so severe that the risk outweighs the benefit of conducting the study in that population. In
p.000031: such populations, biomed- ical HIV prevention trials should not be conducted.
p.000031: Sensitivity to factors of potential vulnerability, including language and cultural barriers, should inform procedures
p.000031: for recruiting and screening potential participants, informed consent processes, and the support, care, and treatment
p.000031: that participants receive in relation to the trial. If a scien- tifically appropriate population is identified as
p.000031: vulnerable to social harm, specific safeguards should be implemented to protect individual partici- pants, such as
p.000031: ensuring confidentiality, the freedom to decline joining the study and the right to withdraw at any time without

p.000005:
p.000005: Well into the third decade of the HIV pandemic, there remains no effective HIV preventive vaccine, microbicide, product
p.000005: or drug to reduce the risk of HIV acquisition. As the numbers of those infected by HIV and dying from AIDS continue to
p.000005: increase, the need for such biomedical HIV preventive interventions becomes ever more urgent. Several such products are
p.000005: at various stages of development, including some currently in phase III efficacy trials. The successful development of
p.000005: effective HIV preventive interven- tions requires that many different candidates be studied simultane- ously in
p.000005: different populations around the world. This in turn will require a large international cooperative effort drawing on
p.000005: partners from various health sectors, inter-governmental organisations, government, research institutions,
p.000005: industry, and affected populations. It will also require that these partners be able and willing to address the
p.000005: difficult ethical concerns that arise during the development of biomedical HIV prevention products.
p.000005:
p.000005: Following deliberations during 1997-99 involving lawyers, activists, social scientists, ethicists, vaccine scientists,
p.000005: epidemiologists, non- governmental organisation (NGO) representatives, people living with HIV, and people working
p.000005: in health policy from a total of 33 countries, UNAIDS published a guidance document on ethical considerations in HIV

p.000030: By definition, HIV prevention research must follow the epidemic. In order to test if a biomedical HIV prevention
p.000030: intervention works, large numbers of individuals at high risk for HIV infection must be recruited for clinical trials.
p.000030: Sites based in communities with mature HIV epidemics have lower incidence rates and may be most appropriate for safety
p.000030: studies. Sites in communities with younger epidemics may be better suited for efficacy trials. However, partici- pating
p.000030: communities and populations, particularly for large-scale efficacy trials, will generally be characterized by
p.000030: multiple vulnera- bilities. The same factors that put these individuals at higher risk for exposure to HIV also make
p.000030: them vulnerable to cultural exclusion, social inequality, economic exploitation, and political oppression. Examples of
p.000030: populations that may have an increased vulnerability include women, children and adolescents, men who have sex with
p.000030: men, injecting drug users, sex workers, transgender persons, indig- enous populations, the poor, the homeless, and

p.000065:
p.000065: People who inject drugs suffer several layers of vulnerability (see Guidance Point 8). Criminalization of their drug
p.000065: use renders them vulnerable to punitive, often harsh, law enforcement practices including incarceration.They may
p.000065: experience additional vulnerability because of generalized stigma and discrimination, including from some health
p.000065: care professionals and policy-makers; personal mental health issues, preceding or resulting from their drug use;
p.000065: poverty; racism, if they are members of certain racially-defined groups; and marginalization. Gender adds an additional
p.000065: layer of vulnerability for people who inject drugs who are women, men who have sex with men, or people who are
p.000065: transgender or intersex. They may experi- ence increased vulnerability to unprotected sex and unsafe injections,
p.000065: exploitation, discrimination, lack of sensitivity to their specific needs, and under-resourcing of services to meet
p.000065: their needs.
p.000065:
p.000065: Prior to commencing a trial, researchers and sponsors should conduct formative research to gain understanding of
p.000065: particular contextual challenges and vulnerabilities that people who inject drugs face and to begin building
p.000065: trust with people who inject drugs and their networks. The research protocol should describe the vulnerabilities
p.000065: identified, as well as steps that have been or will be taken to create a safe enabling environment for trial
p.000065: participants. HIV prevention trials should not be conducted where there are insurmountable barriers to ensure safety,
p.000065: protection, and confidentiality of trial participants (see Guidance Point 18). For this reason, and because adherence
p.000065: to the principle of autonomy cannot be guaranteed, HIV prevention trials should not be conducted in compulsory drug
p.000065: detention centres.

p.000066:
p.000066: In many settings around the world, the consequences of being identi- fied as a person who injects drugs are extremely
p.000066: serious. Precautions should be taken to ensure that recruitment and retention are voluntary, and that people’s
p.000066: right to confidentiality and privacy is not breached (see Guidance Point 18). Recruitment within voluntary drug
p.000066: treatment centres, especially by service providers upon whom people who inject drugs are dependent for on-going
p.000066: care, may pose special problems regarding voluntariness of trial participation. Generally, potential trial
p.000066: participants should not be recruited by their service providers. Where respondent-driven recruitment and other
p.000066: snowball-type recruitment techniques are used, confidenti- ality should be emphasized to recruiters. Research teams
p.000066: should be trained to identify when a potential participant is unable to make a voluntary, informed decision about trial
p.000066: participation. Being under the influence may alone not be sufficient reason to assume lack of capacity to decide.
p.000066: Participants should be clearly informed of any limits to confidentiality to which researchers are bound by regulation.
p.000066:
p.000066: It is not uncommon for people who inject drugs to be incarcerated because of their drug use or for peripheral reasons
p.000066: such as sex work, theft, and vagrancy. Researchers should anticipate that some trial participants could be
p.000066: incarcerated during the course of the trial and should develop an incarceration protocol describing the conditions to
p.000066: be followed to ensure that on-going ethical trial participation is preserved.This should include an option and
p.000066: procedures for voluntary withdrawal of the participant from the trial. The protocol should address confidentiality
p.000066: and voluntariness, access to risk reduction measures while incarcerated, access to a physician, and post-release

p.000029: third party only gives permission to invite individuals to participate and such authorisation or influence must not be

p.000001:
p.000001: Guidance Point 1: Development of Biomedical HIV Prevention Interventions
p.000001: Given the human, public health, social, and economic severity of the HIV epidemic, countries, development partners,
p.000001: and relevant international organisations should promote the establishment and strengthening of sufficient
p.000001: capacity and incentives to foster the early and ethical development of additional safe and effective biomedical HIV
p.000001: prevention methods, both from the point of view of countries and communities in which biomedical HIV prevention trials
p.000001: take place, and from the point of view of trial sponsors and researchers.
p.000001:
p.000001: Guidance Point 2: Community Participation
p.000001: To ensure the ethical and scientific quality and outcome of proposed research, its relevance to the affected community,
p.000001: and its acceptance by the affected community, researchers and trial sponsors should consult communities through a
p.000001: transparent and meaningful participatory process which involves them in an early and sustained manner in the design,
p.000001: development, implementation, monitoring, and distribution of results of biomedical HIV prevention trials.
p.000001:
p.000001: Guidance Point 3: Capacity Building
p.000001: Development partners and relevant international organisations should collaborate with and support countries in
p.000001: strategies to enhance capacity so that countries and communities in which trials are being considered can practice
p.000001: meaningful self-determination in decisions about the scientific and ethical conduct of biomedical HIV prevention trials
p.000001: and can function as equal partners with trial sponsors, local and external researchers, and others in a collaborative
p.000001: process.
p.000001:
p.000001: Guidance Point 4: Scientific and Ethical Review
p.000001: Researchers and trial sponsors should carry out biomedical HIV prevention trials only in countries and communities that
p.000001: have appropriate capacity to conduct independent and competent scientific and ethical review.
p.000001: Guidance Point 5: Clinical Trial Phases
p.000001: As phases I, II, and III in the clinical development of a biomedical HIV preventive intervention all have
p.000001: their own particular scientific requirements and specific ethical challenges, researchers and trial sponsors should
p.000001: justify in advance the choice of study populations for each trial phase, in scientific and ethical terms in all cases,
p.000001: regardless of where the study population is found. Generally, early clinical phases of biomedical HIV prevention
p.000001: research should be conducted in communities that are less vulnerable to harm or exploitation, usually within the
p.000001: sponsor country. However, countries may choose, for valid

p.000002: Ethical considerations in biomedical HIV prevention trials
p.000002:
p.000002:
p.000002: scientific and public health reasons, to conduct any trial phase within their populations, if they are able to ensure
p.000002: sufficient scientific infrastructure and sufficient ethical safeguards.
p.000002: Guidance Point 6: Research Protocols and Study Populations
p.000002: In order to conduct biomedical HIV prevention trials in an ethically acceptable manner, researchers and relevant
p.000002: oversight entities should ensure that the research protocol is scientifically appropriate and that the interventions
p.000002: used in the experimental and control arms are ethically justifiable.
p.000002: Guidance Point 7: Recruitment of Participants.
p.000002: In order to conduct biomedical HIV prevention trials in an ethically acceptable manner, participation of individuals
p.000002: should be voluntary and the selection of participating communities and individuals must be fair and justified in terms
p.000002: of the scientific goals of the research.
p.000002: Guidance Point 8: Vulnerable Populations
p.000002: The research protocol should describe the social contexts of a proposed research population (country or community) that
p.000002: create conditions for possible exploitation or increased vulnerability among potential trial participants, as well as
p.000002: the steps that will be taken to overcome these and protect the rights, the dignity, the safety, and the welfare of the
p.000002: participants.
p.000002: Guidance Point 9: Women
p.000002: Researchers and trial sponsors should recruit women into clinical trials in order to verify safety and efficacy from
p.000002: their standpoint, including immunogenicity in the case of vaccine trials, since women throughout the life span,
p.000002: including those who may become pregnant, be pregnant or be breastfeeding, should be recipients of future safe and
p.000002: effective biomedical HIV prevention interventions. During such research, women should receive adequate information to
p.000002: make informed choices about risks to themselves, as well as to their foetus or breastfed infant, where applicable.
p.000002: Guidance Point 10: Children and Adolescents
p.000002: Children and adolescents should be included in clinical trials in order to verify safety and efficacy from their
p.000002: standpoint, in addition to immunogenicity in the case of vaccines, since they should be recipients of future biomedical
p.000002: HIV preventive interventions. Researchers, trial sponsors, and countries should make efforts to design and implement
p.000002: biomedical HIV prevention product development programmes that address the particular safety, ethical, and legal
p.000002: considerations relevant for children and adolescents, and safeguard their rights and welfare during participation.

p.000003:
p.000003: Guidance Point 11: Potential Harms
p.000003: Research protocols should specify, as fully as reasonably possible, the nature, magnitude, and probability of all
p.000003: potential harms resulting from participation in a biomedical HIV prevention trial, as well as the modalities by which
p.000003: to minimise the harms and mitigate or remedy them.
p.000003: Guidance Point 12: Benefits
p.000003: The research protocol should provide an accurate statement of the anticipated benefit of the procedures and
p.000003: interventions required for the scientific conduct of the trial. In addition, the protocol should outline any services,
p.000003: products, and other ancillary interventions provided in the course of the research that are likely to be beneficial to
p.000003: persons participating in the trials.
p.000003: Guidance Point 13: Standard of Prevention
p.000003: Researchers, research staff, and trial sponsors should ensure, as an integral component of the research protocol, that
p.000003: appropriate counselling and access to all state of the art HIV risk reduction methods are provided to participants
p.000003: throughout the duration of the biomedical HIV prevention trial. New HIV- risk-reduction methods should be added,
p.000003: based on consultation among all research stakeholders including the community, as they are scientifically validated
p.000003: or as they are approved by relevant authorities.
p.000003: Guidance Point 14: Care and Treatment
p.000003: Participants who acquire HIV infection during the conduct of a biomedical HIV prevention trial should be provided
p.000003: access to treatment regimens from among those internationally recognised as optimal. Prior to initiation of a trial,
p.000003: all research stakeholders should come to agreement through participatory processes on mechanisms to provide and sustain
p.000003: such HIV-related care and treatment.
p.000003: Guidance Point 15: Control Groups
p.000003: Participants in both the control arm and the intervention arm should receive all established effective HIV risk
p.000003: reduction measures. The use of a placebo control arm is ethically acceptable in a biomedical HIV prevention trial only
p.000003: when there is no HIV prevention modality of the type being studied that has been shown to be effective in comparable
p.000003: populations.
p.000003: Guidance Point 16: Informed Consent
p.000003: Each volunteer being screened for eligibility for participation in a biomedical HIV prevention trial should provide
p.000003: voluntary informed consent based on complete, accurate, and appropriately conveyed and understood information

p.000004: Ethical considerations in biomedical HIV prevention trials
p.000004:
p.000004:
p.000004: before s/he is actually enrolled in the trial. Researchers and research staff should take efforts to ensure throughout
p.000004: the trial that participants continue to understand and to participate freely as the trial progresses. Informed consent,
p.000004: with pre- and post-test counselling, should also be obtained for any testing for HIV status conducted before, during,
p.000004: and after the trial.
p.000004: Guidance Point 17: Monitoring Informed Consent and Interventions
p.000004: Before a trial commences, researchers, trial sponsors, countries, and communities should agree on a plan for
p.000004: monitoring the initial and continuing adequacy of the informed consent process and risk-reduction interventions,
p.000004: including counselling and access to proven HIV risk-reduction methods.
p.000004: Guidance Point 18: Confidentiality
p.000004: Researchers and research staff must ensure full respect for the entitlement of potential and enrolled participants to
p.000004: confidentiality of information disclosed or discovered in the recruitment and informed consent processes, and during
p.000004: conduct of the trial. Researchers have an ongoing obligation to participants to develop and implement procedures to
p.000004: maintain the confidentiality and security of information collected.
p.000004: Guidance Point 19: Availability of Outcomes
p.000004: During the initial stages of development of a biomedical HIV prevention trial, trial sponsors and countries should
p.000004: agree on responsibilities and plans to make available as soon as possible any biomedical HIV preventive intervention
p.000004: demonstrated to be safe and effective, along with other knowledge and benefits helping to strengthen HIV prevention, to
p.000004: all participants in the trials in which it was tested, as well as to other populations at higher risk of HIV exposure
p.000004: in the country, potentially by transfer of technology.
p.000004: Guidance Point 20: People Who Inject Drugs
p.000004: Researchers and sponsors should include people who inject drugs in biomedical HIV prevention trials in
p.000004: order to verify safety, efficacy, and effectiveness from their standpoint, including immunogenicity in the case of
p.000004: vaccines. As with other key populations at higher risk of HIV exposure, providing people who inject drugs with
p.000004: access to proven, effective HIV preventive interventions is a public health imperative. Researchers and trial
p.000004: sponsors should engage meaningfully with people who inject drugs and with other stakeholders to overcome the complex
p.000004: legal, ethical, and regulatory challenges to the participation in biomedical HIV prevention trials of people who inject
p.000004: drugs. Trial conduct that is ethical is informed by the latest scientific evidence on proven HIV prevention strategies
p.000004: and ensures that participants’ human rights, safety, and welfare are protected.

p.000005: INTRODUCTION
p.000005:
p.000005: Well into the third decade of the HIV pandemic, there remains no effective HIV preventive vaccine, microbicide, product
p.000005: or drug to reduce the risk of HIV acquisition. As the numbers of those infected by HIV and dying from AIDS continue to
p.000005: increase, the need for such biomedical HIV preventive interventions becomes ever more urgent. Several such products are
p.000005: at various stages of development, including some currently in phase III efficacy trials. The successful development of
p.000005: effective HIV preventive interven- tions requires that many different candidates be studied simultane- ously in
p.000005: different populations around the world. This in turn will require a large international cooperative effort drawing on
p.000005: partners from various health sectors, inter-governmental organisations, government, research institutions,
p.000005: industry, and affected populations. It will also require that these partners be able and willing to address the
p.000005: difficult ethical concerns that arise during the development of biomedical HIV prevention products.
p.000005:
p.000005: Following deliberations during 1997-99 involving lawyers, activists, social scientists, ethicists, vaccine scientists,
p.000005: epidemiologists, non- governmental organisation (NGO) representatives, people living with HIV, and people working
p.000005: in health policy from a total of 33 countries, UNAIDS published a guidance document on ethical considerations in HIV
p.000005: preventive vaccine research in 2000. Since then there have been numerous developments related to the conduct
p.000005: of biomedical HIV prevention trials, including vaccine trials. Consultations have been held to explore key issues
p.000005: such as:
p.000005: Creating effective partnerships, collaboration and community participation in HIV prevention trials (International
p.000005: AIDS Society (IAS) 2005; UNAIDS 2006; UNAIDS/AIDS Vaccine Advocacy
p.000005: Coalition (AVAC) 2007);

p.000006:
p.000006: Ethical considerations in biomedical HIV prevention trials
p.000006:
p.000006:
p.000006: The inclusion of adolescents in HIV vaccine trials (WHO/IVR 2002; WHO/UNAIDS 2004; WHO/UNAIDS/African AIDS
p.000006: Vaccine Program 2006);
p.000006: Gender considerations related to enrolment and informed consent (WHO/UNAIDS 2004);
p.000006: Provision of support, care and treatment to participants and the community engaged in HIV prevention trials (WHO/UNAIDS
p.000006: 2003; IAS 2005; UNAIDS 2006; Forum for Collaborative Research 2006; International AIDS Society Industry
p.000006: Liaison Forum 2007;
p.000006: Post-trial responsibilities of sponsors, researchers and local providers (AVAC and the International Council of
p.000006: AIDS Service Organizations, 2005).
p.000006: In light of these consultations, and evolution in the level of prevention, treatment and care available in the era of
p.000006: ‘Towards Universal Access’, the 2000 guidance document was revised and updated. The revision incorporates developments
p.000006: which have taken place since the original publication, including lessons learned in the field of biomedical HIV
p.000006: prevention research. Many different strategies for HIV prevention are now being explored,including
p.000006: microbicides,vaccines,female-initiated barrier methods, herpes simplex virus-2 (HSV-2) treatment/suppres- sion, index
p.000006: partner treatment, antiretroviral pre-exposure prophylaxis, prevention of mother-to-child transmission and drug
p.000006: substitution/ maintenance for injecting drug users. Of note, following the compel- ling evidence of a 50 to 60 per cent
p.000006: reduction in HIV acquisition for men who became circumcised in three randomised controlled trials in South Africa,
p.000006: Kenya and Uganda,WHO/UNAIDS produced recommendations in 2007 judging adult male circumcision to be an accepted risk
p.000006: reduction measure in men, particularly in high preva- lence generalised HIV epidemics in which heterosexual transmis-
p.000006: sion predominates. Finally, the guidelines in this document specifi- cally address trials of biomedical HIV preventive
p.000006: interventions but are relevant to those engaged in trials of various behavioural HIV prevention methods.

p.000007: This document does not purport to capture the extensive discussion, debate, consensus, and disagreement which have
p.000007: taken place among stakeholders in HIV prevention research. Rather it highlights, from the perspective of UNAIDS andWHO,
p.000007: some of the critical ethical elements that must be considered during the development of safe and effective biomedical
p.000007: HIV prevention interventions. Where these are adequately addressed, in the view of UNAIDS/WHO, by other existing texts,
p.000007: there is no attempt to duplicate or replace these texts, which should be consulted extensively throughout biomedical
p.000007: HIV prevention product development activities. Such texts include: the Nuremberg Code (1947); the Declaration of
p.000007: Helsinki, first adopted by theWorld Medical Association in 1964 and most recently amended in 2000 ; the revised
p.000007: International Ethical Guidelines for Biomedical Research Involving Human Subjects,issued in 2002 by the Council for
p.000007: International Organisations of Medical Sciences (CIOMS) (and developed in close cooperation with WHO); the World Health

p.000007: trial sponsors, and ethical and scientific review committees involved in the development of biomedical HIV prevention
p.000007: products and interventions. It suggests standards, as well as processes for arriving at standards which can be used as
p.000007: a frame of reference from which to conduct further discussion at the local,national, and international levels and can

p.000008: CONTEXT
p.000008:
p.000008: The HIV pandemic is characterised by unique biological, social and geographical factors that, among other things,
p.000008: affect the balance of risks and benefits for individuals and communities who participate in biomedical HIV prevention
p.000008: trials.These factors may require that additional efforts be taken to address the needs of participating indi- viduals
p.000008: and communities. They have an urgent need for additional HIV prevention choices for use at various stages of the
p.000008: life-cycle, a need to have their rights protected and their welfare promoted in the context of the development and
p.000008: testing of novel HIV prevention modalities, and a need to be able to participate fully as equal partici- pants in the
p.000008: research process. These factors include the following:
p.000008: The global burden of disease and death related to HIV continues to increase at a rate unmatched by any other pathogen.
p.000008: For many countries, AIDS is the leading cause of death. Currently available treatments do not lead to cure, but
p.000008: do slow the progression of disease.The most effective treatment for slowing HIV-related disease progression,
p.000008: antiretroviral medication, is a life-long treatment which requires close medical monitoring, is still very costly,
p.000008: especially for 2nd line regimens, and can cause significant adverse effects. Because of this, antiretroviral medi-
p.000008: cation is not readily available to the vast majority of people living with HIV who need it. More than 2 million people
p.000008: had access to antiretroviral treatments in low- and middle-income countries in 2006, five times more people than in
p.000008: 2003. But despite this tremendous progress in the roll-out of antiretroviral treatment, global coverage of needs is
p.000008: below 30%.
p.000008: For every person placed on antiretroviral treatment in 2006, another six people became newly infected with HIV. There
p.000008: is therefore an ethical imperative to seek, as urgently as possible, effective and accessible biomedical HIV prevention
p.000008: technolo- gies, to complement existing prevention strategies. This ethical

p.000009:
p.000009: imperative demands that these technologies be developed to address the situation of those people and populations
p.000009: most vulnerable to exposure to HIV infection.
p.000009: Genetically distinct subtypes of HIV have been described, and different HIV subtypes are predominant in different
p.000009: regions and countries. The relevance of these sub-types to probabilities of HIV transmission and acquisition, speed of
p.000009: disease progression and potential protection is not clearly understood.
p.000009: For the conduct of efficacy trials of any biomedical HIV prevention product, the populations with the highest
p.000009: incidence of HIV will be those most likely to be considered for participa- tion and would be those most likely to
p.000009: benefit from an effective intervention. However, for a variety of reasons, these popula- tions may be relatively
p.000009: vulnerable to exploitation and harm in the context of biomedical HIV prevention trials.Trial sponsors, countries,
p.000009: researchers, research staff and community leaders must make additional efforts to overcome this vulnerability.
p.000009: In some biomedical HIV prevention trials, individuals other than the trial participants may experience risks if they
p.000009: are exposed to the experimental product and may experience benefits if the product is effective. For example in trials
p.000009: of prophylaxis of mother-to-child transmission, the foetus is exposed to the prophylactic antiretroviral regimen in
p.000009: addition to the mother. If the mother develops antiretroviral resistance, she may transmit resistant virus to the
p.000009: infant. When the intervention is effective, the newborn baby is protected. In trials of vaginal microbicides, male
p.000009: sexual partners may be exposed to the product even when condoms are used. In trials of successful vaccine candidates,
p.000009: not only sexual partners benefit but communities may benefit from population level effects.
p.000009: Some biomedical HIV prevention modalities may be conceived and manufactured in laboratories of one country
p.000009: (sponsor country or countries), usually in high-income countries, and tested in human populations in another country,
p.000009: often low- and middle-income countries. The potential imbalance of such a

p.000010:
p.000010: situation demands particular attention to ways to address the differing perspectives, interests and capacities of trial
p.000010: sponsors, countries, and communities engaged in trials with the goal of encouraging the urgent development of
p.000010: additional safe and effective biomedical HIV prevention tools, in ethically accept- able manners, and their early
p.000010: distribution to populations most in need. Countries and communities considering participa- tion in biomedical HIV
p.000010: prevention trials should be encour- aged and given the capacity to make decisions for themselves regarding their
p.000010: participation, based on their own health and human development priorities, in a context of equal collabora- tion with
p.000010: sponsors.
p.000010: HIV infection is both highly feared and stigmatised. This is in large part because it is associated with blood, death,
p.000010: sex, and activities which may not be legally sanctioned, such as commer- cial sex, men having sex with men, and illicit
p.000010: substance use. These are issues which are often difficult to address openly
p.000010: - at a societal and individual level. As a result, people living with HIV and those affected by AIDS may experience
p.000010: stigma, discrimination, and even violence; some communities continue to deny the existence and prevalence of HIV
p.000010: infection. Furthermore, vulnerability to HIV exposure and to the impact of AIDS is greater where people are
p.000010: marginalized due to their social, economic, and legal status. These factors increase the risk of social and
p.000010: psychological harm for people participating in biomedical HIV prevention trials. Additional efforts must be made to
p.000010: address these increased risks and to ensure that the risks participants take are justified by the anticipated benefits
p.000010: of the preventive intervention to the participants themselves or to others in the future.
p.000010: A key means by which to protect participants and the commu- nities from which they come is to ensure that the community
p.000010: in which the research is carried out is meaningfully involved in the design, implementation, monitoring, and
p.000010: dissemination of results of HIV prevention trials, including the involvement of representatives from marginalized
p.000010: communities from which participants are drawn.

p.000011: Site selection for moving forward into empirical efficacy trials of biomedical HIV prevention technologies is a
p.000011: major challenge. Part of this challenge is the need to integrate biomedical HIV prevention tool development
p.000011: with other HIV prevention modalities, all of which need to be integrated with HIV treatment and care as provided by the
p.000011: local health care system. It is imperative that appropriate financial arrangements are in place to implement agreements
p.000011: made between partners at the time a study is initiated. These agreements should cover the period of the trial but also
p.000011: address what will be provided to study participants once the study is completed. Advance planning and
p.000011: collaboration between partners is also needed to facilitate timely product licensure and distribution once a
p.000011: method has been proven safe and effective.
p.000011: It has been the experience to date that HIV incidence in both the experimental and control arms of biomedical HIV
p.000011: preven- tion trials tends to fall below the pre-trial incidence, presumably as a result of sustained risk-reduction
p.000011: counselling and provision of effective HIV prevention tools. The discovery of additional safe and effective biomedical
p.000011: HIV preventive interventions will necessitate discussions among all research stakeholders involved in planned or active
p.000011: trials of other biomedical HIV prevention tools. A decision to introduce the new method in a trial that is already
p.000011: underway has to be made collectively as it may have implications for resource requirements, sample sizes, and potential
p.000011: futility of continuing the trial.The possibility that such a decision could be required should be anticipated during
p.000011: initial discussions among the research stakeholders.
p.000011: No single biomedical HIV prevention product or intervention is now or will be 100 per cent effective.This is in part
p.000011: because none are expected to achieve 100 per cent efficacy in the controlled circumstances of a trial and in part
p.000011: because behaviour will influence both consistency and correctness of uptake for many of the interventions being
p.000011: investigated, with the result that the efficacy seen in the trial will not lead to effectiveness at the same level in
p.000011: the real world. Furthermore, the manner in which an effective biomedical HIV prevention product is introduced into

p.000014:
p.000014: Guidance Point 1:
p.000014: Development of Biomedical HIV Prevention Interventions
p.000014:
p.000014: Given the human, public health, social, and economic severity of the HIV epidemic, countries, development
p.000014: partners, and relevant international organisations should promote the establishment and strengthening of sufficient
p.000014: capacity and incentives to foster the early and ethical development of additional safe and effective biomedical HIV
p.000014: prevention methods, both from the point of view of countries and communities in which biomedical HIV prevention
p.000014: trials take place, and from the point of view of trial sponsors and researchers.
p.000014:
p.000014: Given the global nature of the epidemic,the devastation being wrought in some countries by it, the fact that biomedical
p.000014: HIV preventive interventions may be the best long term solution by which to control the epidemic, especially in
p.000014: low- and middle-income countries, and the potentially universal benefits of effective biomedical HIV prevention
p.000014: tools, there is an ethical imperative for global support to develop these modalities. This effort requires intense
p.000014: international collaboration and coordination over time among countries with scientific expertise and resources,
p.000014: and countries in which candidate products could be tested but whose infrastructure, resource base, and scientific and
p.000014: ethical capacities may need strengthening. Though potential HIV prevention tools such as microbicides, vaccines,
p.000014: herpes simplex virus-2 (HSV-2) suppression/treatment, female-initiated barrier methods, index partner treatment,
p.000014: antiretroviral drugs for prophylaxis, and biomedical interventions for injecting drug users should benefit all those
p.000014: in need, it is imperative that they benefit the populations at greatest risk of exposure to HIV. Thus, HIV prevention

p.000015:
p.000015:
p.000015: product development should ensure that products are appropriate for use among such populations, among which it will be
p.000015: necessary to conduct trials; and, when developed, they should be made available and affordable to such populations.
p.000015:
p.000015: Because HIV prevention product development activities take time, are complex, and require infrastructure, resources,
p.000015: and international collaboration,
p.000015: countries who may sponsor trials and countries who may participate in trials should include biomedical HIV
p.000015: prevention product development in their national HIV prevention and control plans.
p.000015: countries who may participate in trials should assess how they can and should take part in biomedical HIV prevention
p.000015: product development activities either nationally or on a regional basis, including identifying resources,
p.000015: establishing partnerships, conducting national information and research literacy campaigns, strengthening their
p.000015: scientific and ethical sectors, and including biomedical HIV prevention product research to complement current
p.000015: comprehensive HIV prevention programming.
p.000015: development partners, international agencies, and governments should make early and sustained commitments to allocate
p.000015: sufficient funds to make biomedical HIV preventive interventions a reality. This includes funds to strengthen ethical
p.000015: and scientific capacity in countries where multiple trials will have to be conducted, to enhance South-South as well as
p.000015: North-South capacity building and technology transfer, and to purchase and distribute future biomedical HIV prevention
p.000015: tools.
p.000015: potential trial sponsors and countries who may participate in trials should establish partnerships with each
p.000015: other, initiate community consultations, support the strengthening of necessary scientific and ethical
p.000015: components, and make plans with all stakeholders for equitable distribution of the benefits of research.

p.000016: Community Participation2
p.000016:
p.000016: To ensure the ethical and scientific quality and outcome of proposed research, its relevance to
p.000016: the affected community, and its acceptance by the affected community, researchers and trial sponsors should
p.000016: consult communities through a transparent and meaningful participatory process which involves them in an
p.000016: early and sustained manner in the design, development, implementation, and distribution of results of biomedical HIV
p.000016: prevention trials.
p.000016:
p.000016: It is highly important to engage in consultations with communities who will participate in the trial from the beginning
p.000016: of the research concept, in an open, iterative, collaborative process that involves a wide variety of participants and
p.000016: takes place under public scrutiny. Participatory management benefits all parties; helps ensure smooth trial
p.000016: functioning; and builds community capacity to understand and inform the research process, raise concerns, and help find
p.000016: solutions to unexpected issues that may emerge once the trial is underway. Failure to properly and genuinely engage
p.000016: communities early in the stages of research planning may result in an inability to properly conduct and complete
p.000016: important trials. Furthermore, active community participation should strengthen not only local ownership of
p.000016: the research, but also the negotiating power of communities, the research skills of local investigators, and the social
p.000016: leverage that can be useful in areas of the society beyond the research trial site. Communities of people affected
p.000016: by research should conversely play an active, informed role in all aspects of its planning and conduct, as well
p.000016: as the dissemination of results. Achieving meaningful participation requires

p.000017: the acknowledgement of structural power imbalances between certain communities and researchers and/or research
p.000017: sponsors, and striving to overcome them. In practical terms, this means putting in place outreach and engagement
p.000017: measures to support participation. Special attention should be paid to the inclusion and empowerment of women for
p.000017: active involvement throughout the research process, as well as to the representation of populations at higher risk of
p.000017: HIV exposure, including adolescents.
p.000017:
p.000017: The nature of community involvement should be one of continuous mutual education and respect, partnership, and
p.000017: consensus-building regarding all aspects of the testing of potential biomedical HIV prevention products. A
p.000017: continuing forum should be established for communication and problem-solving on all aspects of the HIV
p.000017: prevention product development programme from phase I through phase III and beyond (see Guidance Point 6), to the
p.000017: distribution of a safe and effective HIV prevention tool. All participating parties should define the nature of this
p.000017: ongoing relationship. It should include appropriate representation from the community on committees charged with the
p.000017: review, approval, and monitoring of a biomedical HIV prevention trial. As with investigators and sponsors, communities
p.000017: should also assume appropriate responsibility to assure the successful completion of the trial and the product
p.000017: development programme.
p.000017:
p.000017: Defining the relevant community for consultation and partnership is a complex and evolving process that should be
p.000017: discussed with relevant local authorities. As more groups and people define themselves as part of the interested
p.000017: community, the concept needs to be broadened to civil society so as to include advocates, media, human rights
p.000017: organizations, national institutions and governments, as well as researchers and community representatives from the
p.000017: trial site. Partnership agreements should include a clear delineation of roles for all stakeholders and should specify
p.000017: the responsibilities of sponsors, governments, community, advocacy organiza- tions, and media, as well as researchers
p.000017: and research staff.

p.000018: Appropriate community representatives should be determined through a process of broad consultation. An agreement
p.000018: should be reached among stakeholders about the definition of a “community” and ways that it can be effectively
p.000018: represented in decision-making early in the design of the study protocol. The process for determining who will be
p.000018: credible and legitimate community representatives should be addressed through a preliminary consultative process
p.000018: between researchers and key members of the community in which the research is proposed to take place. Members of the
p.000018: community who may contribute to development of a safe and effective HIV prevention product include representatives of
p.000018: the research population eligible to serve as research participants, other members of the community who would be among
p.000018: the intended beneficiaries of the developed product, relevant non- government organisations, persons living with
p.000018: HIV, community leaders, public health officials, and those who provide health care and other services to people living
p.000018: with and affected by HIV.
p.000018:
p.000018: Formal community meetings need to be organised in a way that facili- tates the active participation of those most
p.000018: affected by the research being proposed. The principal investigator and site research staff should work with
p.000018: representatives of affected communities to identify needs related to their participation, including logistical
p.000018: requirements such as trans- portation to the meeting site. Educational materials should be designed in an accessible
p.000018: format, using easy to understand language. Adequate consultation and full participation in the planning process will
p.000018: require more than formal community meetings, as such meetings may alienate some people or be inaccessible to others due
p.000018: to the timing or the format. The principal investigator and site research staff should make efforts to reach out to
p.000018: affected communities, meeting at community centres, workplaces, and other frequented locations. In both formal and
p.000018: informal consultations, the timing and length of the meetings should be convenient for community members, using
p.000018: approaches that facilitate two-way communication with two goals in mind: (1) to identify and

p.000019: understand community concerns and needs, as well as their knowledge and experience, and (2) to clearly describe the
p.000019: research being proposed, related benefits and risks, and other practical implications.
p.000019: Participation of the community in the planning and implementation of a biomedical HIV prevention product development
p.000019: strategy can provide at least these favourable consequences:
p.000019: information regarding the health beliefs and understanding of the study population
p.000019: information regarding the cultural norms and practices of the community
p.000019: input into the design of the protocol
p.000019: input into the design of an effective recruitment and informed consent process
p.000019: insight into the design of risk reduction interventions
p.000019: effective methods for disseminating information about the trial and its outcomes
p.000019: information to the community-at-large on the proposed research trust between the community and researchers
p.000019: equity in eligibility criteria for participation
p.000019: equity in decisions regarding level of care and treatment and its duration, and
p.000019: equity in plans for releasing results and distributing safe and effi- cacious HIV prevention products.
p.000019: Researchers may lack the requisite language, communication skills, and experience to respond to community concerns,
p.000019: while communi- ties may be unfamiliar with research concepts, such as “double blind” and “cause and effect”, and may
p.000019: not define HIV prevention research as a priority. This underscores the need for “joint literacy”, whereby researchers
p.000019: and community groups become sufficiently fluent in the requisite concepts and language to work productively
p.000019: together. Research literacy programs that include ethics training for study staff can facilitate and enhance
p.000019: cooperation with civil society groups.

p.000020: Capacity Building
p.000020:
p.000020: Development partners and relevant international organisations should collaborate with and support countries in
p.000020: strategies to enhance capacity so that countries and communities in which trials are being considered can practice
p.000020: meaningful self-determination in decisions about the scientific and ethical conduct of biomedical HIV prevention trials
p.000020: and can function as equal partners with trial sponsors, local and external researchers, and others in a collaborative
p.000020: process.
p.000020:
p.000020: Countries and communities who choose to participate in biomedical HIV prevention trials have the right, and the
p.000020: responsibility, to make decisions regarding the nature of their participation. Yet disparities in economic wealth,
p.000020: scientific experience, and technical capacity among countries and communities have raised concern about possible
p.000020: exploitation of participant countries and communities. The develop- ment and testing of biomedical HIV preventive
p.000020: interventions requires international cooperative research, which should transcend, in an ethical manner, such
p.000020: disparities. Real or perceived disparities should be resolved in a way that ensures equality in decision-making and
p.000020: action. The desired relationship is one of equals, whose common aim is to develop a long-term partnership through
p.000020: South-South as well as North-South collaboration that sustains site research capacity.
p.000020:
p.000020: Factors that affect perceptions of disparity in power between sponsors and the countries and communities in which
p.000020: research takes place may include, but are not limited to, the following:

p.000021: scientific exchange, and knowledge and skills transfer, between sponsors, researchers, communities and their

p.000021: capacity-building programmes in the science and ethics of biomedical HIV prevention research by relevant
p.000021: scientific insti- tutions and local and international organisations;
p.000021: support to develop national and local ethical review capacity (see Guidance Point 4);
p.000021: support to communities from which participants are drawn regarding information, education, and

p.000022:
p.000022: Proposed biomedical HIV prevention trial protocols should be reviewed by scientific and ethical review committees that
p.000022: are located in, and include membership from, the country in which researchers wish to operate. Trials should register
p.000022: with an international trial registry prior to committee review as a condition of approval. Community repre- sentatives
p.000022: should also be involved in review of the trial protocol to insure that the research is informed by the concerns and
p.000022: priorities of the community in which the study is to take place. This process ensures that the proposed research is
p.000022: analysed in scientific and ethical terms by individuals who are familiar with the conditions prevailing in the
p.000022: potential research population. Reviewers should not allow research to begin unless the potential benefits of the
p.000022: experimental intervention outweigh the risks to participating individuals and groups. Independent ethical review of
p.000022: research protocols ensures public accountability and also minimizes concerns with regard to researchers’ conflicts of
p.000022: interest because of relationships with the sponsors or pressures from those promoting the research.The scientific and
p.000022: ethical review should involve individuals with training in science, statistics, ethics, and law.

p.000024: Clinical Trial Phases
p.000024:
p.000024: As phases I, II, and III in the clinical development of a biomedical HIV preventive intervention all have their
p.000024: own particular scientific requirements and specific ethical challenges, researchers and trial sponsors should justify
p.000024: in advance the choice of study populations for each trial phase, in scientific and ethical terms in all cases,
p.000024: regardless of where the study population is found. Generally, early clinical phases of biomedical HIV
p.000024: prevention research should be conducted in communities that are less vulnerable to harm or exploitation,
p.000024: usually within the sponsor country. However, countries may choose, for valid scientific and public health
p.000024: reasons, to conduct any trial phase within their populations, if they are able to ensure sufficient scientific
p.000024: infrastructure and sufficient ethical safeguards.
p.000024:
p.000024:
p.000024: The initial pre-clinical phase in the development of a biomedical HIV prevention product entails research in
p.000024: laboratories and among animals. The transition to a phase I clinical trial in which testing involves the
p.000024: administration of the product to human subjects to assess safety, and in the case of vaccines to assess immunogenicity,
p.000024: is a time when risks may not yet be well-defined. Hence, specific infrastructures are often required in order to ensure
p.000024: the safety and care of the research participants at these stages. For these reasons, the first administration of a
p.000024: candidate biomedical HIV prevention product in humans should generally be conducted in populations which are not at
p.000024: risk of HIV acquisition, usually in the country of the trial sponsor.
p.000024:
p.000024: Clinical trial researchers have been designing trials that fall somewhere between phase II (expanded safety and
p.000024: immunogenicity) and phase III (large scale trials to assess efficacy) – called phase IIB trials, or proof of concept
p.000024: trials. Phase IIB trials may provide an indication of

p.000025:
p.000025: UNAIDS / WHO guidance document
p.000025:
p.000025:
p.000025: an experimental candidate’s efficacy but are less costly in terms of money, time, and number of trial participants.
p.000025: However, such phase IIB trials are not designed to provide enough information for regula- tory approval at the end of
p.000025: the trial for an HIV prevention product subject to regulation; instead, these trials test the general concept of the
p.000025: candidate product and efficiently filter out products that lack efficacy. Eventually, a phase III trial would have to
p.000025: be conducted to develop a useable and licensable HIV product.
p.000025:
p.000025: There may be situations where low- and middle-income countries choose to conduct phases I/II and/or IIB and III
p.000025: among their populations that are relatively vulnerable to risk and exploitation. For instance, this could occur where
p.000025: an experimental HIV vaccine is directed primarily toward a viral strain that does not exist in the trial sponsor’s
p.000025: country but does exist in the country in which it is proposed the trial be conducted. Conducting phase I/II trials in
p.000025: the country where the strain exists may be the only way to determine whether safety and immunogenicity are acceptable
p.000025: in that particular population, prior to conducting a phase III trial. Another example might be a country that decides
p.000025: that, due to the high level of HIV risk to its population and the gravity of HIV prevalence in the country, it is
p.000025: willing to test a biomedical HIV prevention product concept that has not or is not being tested in another country.
p.000025: Such a decision may result in obvious benefits to the country in question if an effective product is eventually found.
p.000025: If phase I or phase II trials are conducted in the country intending to participate in an eventual phase III trial, if
p.000025: phases I and II are satisfactory, this may assist in building capacity for phase III trial conduct, including
p.000025: increasing levels of research literacy in the population.
p.000025:
p.000025: Establishing a biomedical HIV prevention product development programme that entails the conduct of some,
p.000025: most, or all of its clinical trial components in a country or community that is rela- tively vulnerable to harm or
p.000025: exploitation is ethically justified if:

p.000026: ethical capability and administrative and health infrastructure for the successful conduct of the proposed research;
p.000026: community members, policy makers, ethicists, and investiga- tors in the country have determined that their residents

p.000026:
p.000026: In cases in which it is decided to carry out phase I or phase II trials first in a country other than the trial

p.000026: sponsor, where this is practical and ethical. Also, as a general rule, phase I/II trials that have been performed in
p.000026: the country of the trial sponsor should ordinarily be repeated in the community in which the phase III trials are to be
p.000026: conducted, although this may not be needed, particularly in situations in which a product has demonstrated unexpectedly
p.000026: high efficacy.

p.000027: Research Protocols and Study Populations
p.000027:
p.000027: In order to conduct biomedical HIV prevention trials in an ethically acceptable manner, researchers and relevant
p.000027: oversight entities should ensure that the research protocol is scientifically appropriate and that the interventions
p.000027: used in the experimental and control arms are ethically justifiable.
p.000027:
p.000027:
p.000027: In order to be ethical, clinical trials of novel biomedical HIV preven- tion tools should be based on scientifically
p.000027: valid research protocols, and the scientific questions posed should be rigorously formulated in a research protocol
p.000027: that is capable of providing reliable responses.Valid scientific questions relevant to biomedical HIV prevention
p.000027: product development are those that seek:
p.000027:
p.000027: to gain scientific information on the safety and efficacy (degree of protection) of candidate biomedical HIV prevention
p.000027: products, and, in the case of vaccine candidates, immunogenicity (ability to induce immune responses against HIV);
p.000027: to determine correlates or surrogates of safety and protection in order to better characterise and elicit protective
p.000027: mechanisms;
p.000027: to compare different candidate products; and
p.000027: to test whether biomedical HIV prevention products effective in one population are effective in other populations.
p.000027: Furthermore, the selection of the research population should be based on the fact that its characteristics are
p.000027: relevant to the scientific issues raised; and the results of the research will potentially benefit the selected
p.000027: population. In this sense, the research protocol should:
p.000027:

p.000028: Recruitment of Participants
p.000028:
p.000028: In order to conduct biomedical HIV prevention trials in an ethically acceptable manner, participation of individuals
p.000028: should be voluntary and the selection of participating communities and individuals must be fair and justified in terms
p.000028: of the scientific goals of the research.
p.000028:
p.000028:
p.000028: Selection and recruitment of communities and individuals for partici- pation in a trial must be fair and should create
p.000028: a research climate which shows respect for all persons.This encompasses decisions about who will be included
p.000028: through the formulation of inclusion and exclusion criteria, and through the strategy adopted for recruiting
p.000028: participants. The scientific goals of the study should be the primary basis for determining the individuals who
p.000028: will be recruited and enrolled. Individuals should not be excluded from the opportunity to participate without a
p.000028: good scientific reason or a susceptibility to risk that justifies their exclusion. Social and cultural factors should
p.000028: be considered to determine the vulnerability within the community of individuals who are either included or excluded.
p.000028: In particular, gender- sensitive approaches are key when designing recruitment procedures and special attention needs
p.000028: to be paid to the inclusion or exclusion of pregnant women.

p.000030: Vulnerable Populations
p.000030:
p.000030: The research protocol should describe the social contexts of a proposed research population (country or
p.000030: community) that create conditions for possible exploitation or increased vulnerability among potential trial
p.000030: participants, as well as the steps that will be taken to overcome these and protect the rights, the dignity, the
p.000030: safety, and the welfare of the participants.
p.000030:
p.000030:
p.000030: By definition, HIV prevention research must follow the epidemic. In order to test if a biomedical HIV prevention
p.000030: intervention works, large numbers of individuals at high risk for HIV infection must be recruited for clinical trials.
p.000030: Sites based in communities with mature HIV epidemics have lower incidence rates and may be most appropriate for safety
p.000030: studies. Sites in communities with younger epidemics may be better suited for efficacy trials. However, partici- pating
p.000030: communities and populations, particularly for large-scale efficacy trials, will generally be characterized by
p.000030: multiple vulnera- bilities. The same factors that put these individuals at higher risk for exposure to HIV also make
p.000030: them vulnerable to cultural exclusion, social inequality, economic exploitation, and political oppression. Examples of
p.000030: populations that may have an increased vulnerability include women, children and adolescents, men who have sex with
p.000030: men, injecting drug users, sex workers, transgender persons, indig- enous populations, the poor, the homeless, and
p.000030: communities from resource-poor settings in high-income and low- and middle-income countries. At the same time, it is
p.000030: precisely these populations who stand to benefit most from the successful development of a new biomedical HIV
p.000030: prevention product or method. For these reasons, it is imperative to ensure protection of the rights of participants
p.000030: in biomedical HIV prevention trials, and respect for their dignity, safety, and welfare.

p.000031:
p.000031:
p.000031: Decision-making around conducting a biomedical HIV prevention trial needs to consider in what ways the trial might
p.000031: increase or decrease vulnerabilities. On the one hand, a trial might increase a participant’s risk of exposure to
p.000031: stigmatisation and discrimination if it highlights a population’s increased vulnerability to HIV exposure. On the
p.000031: other hand, a trial might decrease vulnerability, if it empowers the community or provides tangible assistance to
p.000031: participants, for example by improving the accessibility, affordability, and quality of appropriate healthcare
p.000031: services in the community. A social and political analysis should be carried out early on in planning the research
p.000031: process, to assess determi- nants of vulnerability, such as poverty, gender, age, ethnicity, sexuality, health,
p.000031: employment, education, and legal conditions in potential partic- ipating communities. Findings from this analysis
p.000031: should inform the design of research protocols, which should be sensitive to emerging information on incidental risks
p.000031: of social harm throughout the course of a trial. Research protocols might also include ongoing independent monitoring
p.000031: of a trial in relation to its impact on the vulnerabilities of communities participating in the study (see Guidance
p.000031: Point 17).
p.000031: The particular aspects of a social context that create conditions for exploi- tation or increased vulnerability should
p.000031: be described in the research protocol, as should the safeguards and measures that will be taken to prevent and overcome
p.000031: them. In some potential research populations (countries or communities), conditions affecting potential vulnerability
p.000031: or exploitation may be so severe that the risk outweighs the benefit of conducting the study in that population. In
p.000031: such populations, biomed- ical HIV prevention trials should not be conducted.
p.000031: Sensitivity to factors of potential vulnerability, including language and cultural barriers, should inform procedures
p.000031: for recruiting and screening potential participants, informed consent processes, and the support, care, and treatment
p.000031: that participants receive in relation to the trial. If a scien- tifically appropriate population is identified as
p.000031: vulnerable to social harm, specific safeguards should be implemented to protect individual partici- pants, such as
p.000031: ensuring confidentiality, the freedom to decline joining the study and the right to withdraw at any time without
p.000031: penalty.

p.000032: Women
p.000032:
p.000032: Researchers and trial sponsors should include women in clinical trials in order to verify safety and
p.000032: efficacy from their standpoint, including immunogenicity in the case of vaccine trials, since women throughout the
p.000032: life span, including those who are sexually active and may become pregnant, be pregnant or be breastfeeding,
p.000032: should be recipients of future safe and effective biomedical HIV prevention interventions. During such research,
p.000032: women’s autonomy should be respected and they should receive adequate information to make informed choices
p.000032: about risks to themselves, as well as to their foetus or breastfed infant, where applicable.
p.000032:
p.000032:
p.000032: Women throughout the life span, including those who are sexually active and may become pregnant, be pregnant or be
p.000032: breastfeeding, should be recipients of future safe and effective biomedical HIV prevention products and therefore
p.000032: should be eligible for enrolment in biomedical HIV prevention trials, both as a matter of equity and because in many
p.000032: communities throughout the world women, particularly young women, are at higher risk of HIV exposure.
p.000032: Therefore, the efficacy of candidate biomedical HIV prevention products, and their immunogenicity in the case of
p.000032: vaccines, should be established for women. Clinical trials should also be designed with the intent of establishing the
p.000032: safety of candidate biomedical prevention products for the health of the woman and, where appli- cable, her foetus,
p.000032: breastfed infant and, in the case of vaginal or rectal microbicides, her sexual partners.
p.000032:
p.000032: If the safety of the biomedical HIV prevention product for a pregnant women and her foetus has not been established
p.000032: prior to commence- ment of the trial, women who become pregnant in the course of the trial might be discontinued from
p.000032: using the product, which would

p.000033: result in loss to follow-up of the participating women.Therefore the question of whether a safety study for pregnant
p.000033: women should be conducted early on in the research, at the stage when a candidate has sufficient promise to advance
p.000033: into a Phase IIB or Phase III efficacy trial in adults or only after the trial product has been shown to be effective
p.000033: should be discussed and resolved on a case-by-case basis early on in the planning of the research design. In any event,
p.000033: researchers should monitor adverse events among pregnant women and women who become pregnant in the course of the
p.000033: trial, notably in the case of a miscarriage, to determine their relatedness to the biomedical HIV preventive
p.000033: intervention.
p.000033:
p.000033: The most notable data gap in the evaluation of some prevention methods, particularly in phase I and II trials, is
p.000033: adequate evaluation of safety and efficacy among women. Barriers for women partici- pating in trials include
p.000033: contraceptive requirements, issues related to current or future fertility, concerns about safety for the foetus, and
p.000033: fear of being labelled as being at higher risk for HIV exposure. Also, women present issues of particular complexity
p.000033: with regard to recruitment and informed consent. In some cultures, women and girl adolescents may not be able to
p.000033: exercise true autonomy in light of the influence of their parents or sexual partners (see Guidance Point 7). In others,
p.000033: young people may be more informed than their parents, and their view and their parents’ or partners’ views on
p.000033: their participation may differ. Further, the need for HIV testing or pregnancy testing to assess eligibility for
p.000033: inclusion in a trial may raise difficult issues regarding the maintenance of appropriate confi- dentiality.
p.000033: Researchers and research staff should improve recruit- ment strategies by anticipating and finding solutions to
p.000033: address and overcome these barriers (see Guidance Point 7). Appropriate reproductive and sexual health counselling
p.000033: and ancillary services, including family planning, should be provided to trial participants.

p.000034:
p.000034: Although the enrolment of pregnant or breastfeeding women complicates the analysis of risks and benefits,
p.000034: because both the woman and the foetus or infant could be benefited or harmed, such women should be viewed as
p.000034: autonomous decision-makers, capable of making an informed choice for themselves and for their foetus or child. In order
p.000034: for pregnant women to be able to make an informed choice for their foetus/breastfed infant,they should be duly informed
p.000034: about any potential for teratogenesis and other known or unknown risks to the foetus and/or the breastfed infant. If
p.000034: there are risks related to breastfeeding, women should be informed of the availability of nutritional substitutes and
p.000034: other supportive services. Researchers should observe and study the positive and adverse effects on the children of
p.000034: these women.They should maintain pregnancy registries to collect data on outcomes of pregnancies that inadvertently
p.000034: occur during the trial, follow-up babies born to women participants, and take due measures for protection of privacy
p.000034: and personal data. In the particular case of trials of prevention of mother-to-child transmis- sion, both women and

p.000034: potential for effects on subsequent therapeutic options.

p.000035: Children and adolescents should be included in clinical trials in order to verify safety and efficacy from
p.000035: their standpoint, in addition to immunogenicity in the case of vaccines, since they should be recipients of
p.000035: future biomedical HIV preventive interventions. Researchers, trial sponsors, and countries should make

p.000035: particular safety, ethical, and legal considerations relevant for children and adolescents, and safeguard their rights
p.000035: and welfare during participation.
p.000035:
p.000035: Children3 , including infants and adolescents, should be eligible for enrolment in biomedical HIV preventive
p.000035: intervention trials, both as a matter of equity and because in many communities throughout the world children are at a
p.000035: higher risk of HIV exposure. Infants born to HIV-infected mothers are at risk of becoming infected during birth and
p.000035: during the postpartum period through breastfeeding. Many adolescents are also at higher risk of HIV infection due to
p.000035: sexual activity, lack of access to HIV prevention education and means, and through injecting drugs with non-sterile
p.000035: equipment.
p.000035:
p.000035: Therefore, biomedical HIV prevention product development programmes should consider the needs of children

p.000036: situation can be met. Those designing biomedical HIV prevention product development programmes that might include
p.000036: children should do so in consultation with groups dedicated to the protec- tion and promotion of the rights and welfare
p.000036: of children, both at international and national levels.
p.000036:
p.000036: It is generally understood that adolescents, prior to initiation of sexual activity and exposure to any risk of HIV
p.000036: infection, will be the primary target for any public health intervention involving a successful biomedical
p.000036: intervention. In the case of HIV vaccine candidates and other products requiring licensure that would have an
p.000036: indication for use in both adolescents and adults, it is impera- tive that there be no delays in achieving simultaneous
p.000036: licensure/ registration for both populations. It is therefore recommended in such cases, that adolescents be included
p.000036: in trials as soon as possible when a candidate has sufficient promise to advance into a Phase IIB or Phase III efficacy
p.000036: trial in adults (see Guidance Point 5). The use of bridging studies designed for safety (and, in the case of an HIV
p.000036: vaccine, immunogenicity testing), but not including HIV infection as a primary endpoint could be considered as an
p.000036: alterna- tive for younger adolescents, to be carried out in parallel to Phase III trials in adults.
p.000036:
p.000036: There may be legal barriers to enrolment of younger adolescents into a clinical trial in which sexual activity is
p.000036: directly linked to achieving primary endpoints. It is imperative that trials are conducted in compliance with the
p.000036: protective laws and regulations applicable at the trial sites, including those related to legal age of consent, the age
p.000036: of majority, the legal age for consensual sex, legal obligations to report abuse or neglect, and other aspects which
p.000036: may have an impact on the conduct of biomedical HIV preventive intervention trials. Thus, undertaking a survey of
p.000036: applicable local laws is an essential requirement to ensure required compliance prior to making plans for such trials
p.000036: in a particular country.

p.000037: As with all other trials involving children, the permission of a parent or legal guardian is required along with the
p.000037: assent of the child. Unless exceptions are authorised by national legislation, consent to participate in a biomedical
p.000037: HIV preventive intervention trial must be secured from the parent or guardian of a child who is a minor, before the
p.000037: enrolment of the child as a participant in a vaccine trial. The consent of one parent is generally sufficient, unless
p.000037: national law requires the consent of both. Every effort should be made to obtain assent to participate in the trial
p.000037: also from the child according to the evolving capacities of the child, and his or her refusal to participate should be
p.000037: respected.
p.000037:
p.000037: In some jurisdictions, individuals who are below the age of consent are authorised to receive, with their active
p.000037: consent and without the consent or awareness of their parents or guardians, such medical services as therapeutic
p.000037: abortion, contraception, treatment for illicit drug use or alcohol abuse, and treatment of sexually transmitted
p.000037: infections. In some of these jurisdictions, such minors are also authorised to consent to serve as
p.000037: participants in research in the same categories without the agreement or the awareness of their parents or guardians,
p.000037: provided the research presents no more than “minimal risk”. However, such authorisation does not justify the enrolment
p.000037: of minors as participants in biomedical HIV prevention trials without the consent of their parents or guardians.
p.000037:
p.000037: In some jurisdictions, some individuals who are below the general age of consent are regarded as “emancipated” or
p.000037: “mature” minors and are authorised to consent without the agreement or even the awareness of their parents or
p.000037: guardians. These may include those who are married, parents, pregnant or living independently. When authorised by
p.000037: national legislation, minors in these categories may consent to participation in biomedical HIV prevention trials
p.000037: without the permission of their parents or guardians.

p.000038:
p.000038: During the informed consent process, it is recommended that investigators conduct the consent (parent) and
p.000038: assent (adolescent) processes separately. This would ensure confidential counselling for the adolescent and protect the
p.000038: adolescent’s privacy (see Guidance Point 18). It is also important to inform adolescents of all the elements
p.000038: disclosed to an adult, and to determine that the adoles- cent understands what s/he is assenting to (see Guidance Point
p.000038: 16). The consent process and document should describe clearly what information regarding the adolescent will or will
p.000038: not be disclosed to the parent(s) or legal guardian, as well as what medical or other services will be provided to
p.000038: the adolescent, as needed, without further parental permission.
p.000038:
p.000038: In some settings, children may have guardians who have not been legally recognized by a court as such. Adolescents who
p.000038: do not have parents or legally recognized guardians should not be automatically excluded from participation in a
p.000038: biomedical HIV preventive inter- vention trial. Participation could be considered for such adolescents who wish to
p.000038: participate in a trial, as long as a protective ethical oversight mechanism can be established in compliance with the
p.000038: local law. In addition, mechanisms should be established for an independent evaluation of the capacity of such
p.000038: adolescents to give informed consent.

p.000039:
p.000039: Participation in biomedical HIV prevention trials may involve physi- ological, psychological, and social risks.
p.000039: Participation in a compli- cated, lengthy trial involving intensely intimate matters, repeated HIV testing, and
p.000039: exposure to culturally different scientific and medical concepts may cause anxiety, stress, depression, as well as
p.000039: stress between partners in a relationship. Legal regulations for HIV disclosure may require partner notification
p.000039: when volunteers test-positive or trial participants acquire HIV infection (see Guidance Point 18).
p.000039:
p.000039: Participation, if it becomes publicly known, may also cause stigma and discrimination against the participant if s/he
p.000039: is perceived to be HIV- infected or at higher risk of acquiring HIV infection, particularly for women and adolescents,
p.000039: and already marginalised populations. HIV has been associated with illicit behaviour, including injecting drug use, sex
p.000039: work, and sexual relations between men, as well as with behaviours which may not be condoned such as premarital or
p.000039: extra- marital sexual activity. Discrimination can take the form of accusa- tions or abuse, can affect marriage
p.000039: prospects, and can result in social ostracism, job loss, denial of property or inheritance rights, or the denial of
p.000039: health care.Women may be at heightened risk of domestic violence as a result of trial participation. Trial sponsors,

p.000040: In trials of microbicides, vaccines, HSV-2 suppression and antiret- roviral pre-exposure prophylaxis, there may be
p.000040: unknown risks to a foetus exposed to the product. In trials of prevention of mother-to- child transmission, mothers may
p.000040: develop antiretroviral drug resistance and may transmit resistance virus to their infants; infants may develop
p.000040: resistance during prophylaxis while breastfeeding.
p.000040:
p.000040: Despite previous safety testing of microbicide products, trial partici- pants and/or sexual partners who are exposed to
p.000040: the product may experience adverse effects, including those which may increase risk of HIV acquisition. In the case of
p.000040: microbicides containing antiret- roviral drugs, there may be systemic absorption of active ingredients with possible
p.000040: development of antiretroviral resistance should HIV infection be acquired. In pre-exposure prophylaxis trials,
p.000040: individuals who acquire HIV infection may develop resistance to the antiretro- viral drug in the experimental product.
p.000040:
p.000040: Vaccine trial participants who are exposed to HIV may have a greater risk of developing established infection, or

p.000041:
p.000041: The potential for adverse reactions to a candidate biomedical HIV prevention product, as well as possible injuries
p.000041: related to the conduct of biomedical HIV prevention research, should be described, as far as possible, in the research

p.000041: research- related activities and the process by which it will be decided whether an injury will be compensated. HIV
p.000041: infection acquired during partic- ipation in a biomedical HIV prevention trial should not be consid- ered a compensable
p.000041: injury unless directly attributable to the preven- tion product being tested itself, or to direct contamination through
p.000041: a research-related activity. In addition to compensation for trial-related biological/medical injuries, appropriate
p.000041: consideration should be given to compensation for social or economic harms.

p.000042: Benefits
p.000042:
p.000042: The research protocol should provide an accurate statement of the anticipated benefit of the procedures and
p.000042: interventions required for the scientific conduct of the trial. In addition, the protocol should outline any
p.000042: services, products, and other ancillary interventions provided in the course of the research that are likely to be
p.000042: beneficial to persons participating in the trials.
p.000042:
p.000042:
p.000042: Clinical research inherently entails uncertainty about the degree of risk and benefits, with earlier phases of research
p.000042: having greater uncertainty. Proceeding to a human trial can be justified only if there is reasonable biological
p.000042: plausibility that a product could be safe and effective, and there is equipoise – meaning that whether a product will
p.000042: actually work is unknown but there is a favourable risk-benefit ratio. Only anticipated benefits of study-related
p.000042: procedures required for the safe and scientific conduct of the trial should be considered in the risk-benefit analysis,
p.000042: that is, only health care benefits derived directly from the study design. Extraneous benefits, such as payment or
p.000042: ancillary services, such as HIV risk-reduction interventions or reproductive health care services, should not be
p.000042: considered in the risk-benefit analysis. Scientific and ethical review committees must be satisfied that the potential
p.000042: risks to individual subjects are minimized, the potential benefits to individual participants are enhanced, and the
p.000042: potential benefits to individual participants and the community are proportionate to or outweigh the risks.
p.000042:
p.000042: There should be an ongoing iterative consultative process to facili- tate local or national decision-making about the
p.000042: appropriate level of support, care, and treatment provided to potential and enrolled partic- ipants. Some of the
p.000042: activities related to the conduct of HIV biomed- ical HIV prevention trials which may benefit those who participate may
p.000042: actually be rights. At a minimum, participants should:

p.000043:
p.000043:
p.000043: have regular and supportive contact with health care workers and counsellors throughout the course of the trial;
p.000043: receive comprehensive information regarding HIV transmission and how it can be prevented;
p.000043: receive access to HIV testing and prevention methods, including male and female condoms, sterile injecting equipment,
p.000043: and sexual and reproductive health care services; and
p.000043: have access to a pre-defined care and treatment package for HIV- related illness if they become HIV-infected while
p.000043: enrolled in the trial (see Guidance Point 14).
p.000043: Participants should also receive reimbursement for travel and other expenses related to participation in a biomedical
p.000043: HIV prevention trial. In recognising the time and inconvenience their participation entails, the appropriate form and
p.000043: level of extraneous non-health incentives will depend on the local economic and social context.
p.000043:
p.000043: Some have contended that to promise antiretroviral treatment to HIV prevention trial participants who become infected
p.000043: would constitute an undue inducement to participate in the trial. That supposition is most unlikely, since biomedical
p.000043: HIV prevention trials enrol healthy people, not individuals who are already sick and need treatment. If anything, the
p.000043: possibility of being protected from acquiring HIV by the preventive method itself could conceivably be considered an
p.000043: undue inducement; however, if that were the case, clinical trials of preven- tive methods could never be ethically
p.000043: carried out. Concerns that any form of care and treatment promised to participants in research on biomedical HIV
p.000043: preventive interventions could be an undue induce- ment are unwarranted.
p.000043:
p.000043: Some may argue that provision of state-of-the-art prevention, care, and treatment services for participants introduces
p.000043: local inequalities and is therefore unjust when non-participants do not receive those services. However, all scale-up
p.000043: programmes involve temporary inequalities in the community until universal access can be attained. Achieving a perfect
p.000043: system of equal justice is a long-term process.

p.000044: Standard of Prevention
p.000044:
p.000044: Researchers, research staff, and trial sponsors should ensure, as an integral component of the research
p.000044: protocol, that appropriate counselling and access to all state of the art HIV risk reduction methods are
p.000044: provided to participants throughout the duration of the biomedical HIV prevention trial. New HIV-risk-reduction
p.000044: methods should be added, based on consultation among all research stakeholders including the community, as
p.000044: they are scientifically validated or as they are approved by relevant authorities.
p.000044:
p.000044:
p.000044: The ethical principle of beneficence obligates researchers and sponsors to maximise benefits and minimise risks to
p.000044: participants in clinical trials. This obligation pertains not only to the preventive method being studied, but also to
p.000044: reducing the risk that any trial participant will acquire HIV infection during a biomedical HIV prevention trial.
p.000044:
p.000044: Protocols for HIV prevention research obligate researchers to provide the full range of information and services for
p.000044: risk reduction, although they vary in defining the package of services and modes of delivery. If the study aims to test
p.000044: a product by comparing its additive effects to those of routinely practiced prevention, in all cases this preven- tion
p.000044: standard should be defined in the study protocol as well as in informed consent documents. If researchers are unable to
p.000044: guarantee that this standard is met, it is unethical to conduct the proposed trial.
p.000044:
p.000044: Risk-reduction packages should include provision for family planning, pregnancy and childbirth services. Women may
p.000044: become pregnant during a trial. Some of these women may wish to carry the babies to term, some might have miscarriages,
p.000044: and some might elect to have therapeutic abortions. Researchers should guarantee that all commu- nities engaged in
p.000044: biomedical HIV prevention trials have state of the art reproductive health care services.

p.000045: on public health practice, such as the provision of therapeutic abortion services or the provision of
p.000045: appropriate risk-reduction interventions for trial participants who inject drugs, including sterile injecting
p.000045: equipment and drug substitution treatment.
p.000045:
p.000045: All trial participants should receive HIV risk-reduction counselling, as well as access and entitlement to proven
p.000045: prevention methods, and to post-exposure prophylaxis in the event of a known likely exposure. Comprehensive counselling
p.000045: should include the basic principles of safer sexual practice and safer injecting practices, as well as education
p.000045: concerning general health and treatment of sexually transmitted infections (STIs), reproductive health
p.000045: (contraception, pregnancy care etc.), and strategies to reduce domestic violence. Investigators should provide trial
p.000045: participants appropriate access to male and female condoms, sterile injecting equipment, medical substitution
p.000045: therapy such as methadone or buprenorphine maintenance, and treatment for other STIs. All trial participants
p.000045: should also be counselled at the beginning of a biomedical HIV prevention trial regarding the potential benefits
p.000045: and risks of post-exposure prophylaxis with antiret- roviral medication, and how it can be accessed in the community.
p.000045: Ways should be explored with local authorities to provide trial volun- teers and participants with information about
p.000045: HIV prevention and treatment services available in the community. Referral mechanisms should be established and

p.000047: Care and Treatment
p.000047:
p.000047: Participants who acquire HIV infection during the conduct of a biomedical HIV prevention trial should be
p.000047: provided access to treatment regimens from among those internationally recognised as optimal. Prior to initiation of
p.000047: a trial, all research stakeholders should come to agreement through participatory processes on mechanisms to provide
p.000047: and sustain such HIV-related care and treatment.
p.000047:
p.000047: The obligation on the part of sponsors and investigators to ensure access to HIV care and treatment, including
p.000047: antiretroviral treatment, for participants who become infected derives from some or all of three ethical principles.
p.000047: The principle of beneficence requires that the welfare of participants be actively promoted. The principle of justice
p.000047: as reciprocity calls for providing something in return to participants who have volunteered their time, been
p.000047: inconvenienced or experi- enced discomfort by enrolling in the trial. The principle of justice, meaning treating like
p.000047: cases alike, requires that trial participants in high- income and low- and middle-income countries be treated equally
p.000047: regarding access to treatment and care.
p.000047: A consensus on the level of care and treatment that should be provided to trial participants has emerged in
p.000047: recent years with increasing accessibility of antiretroviral treatment in low- and middle-income countries, based on
p.000047: strong commitments from countries, development partners and multilateral organizations; dramatic decreases in drug
p.000047: prices; and evidence that treatment programmes in resource-poor settings are feasible and sustainable. There is
p.000047: consensus that sponsors need to ensure access to internationally recognised optimal care and treatment regimens,
p.000047: including antiretroviral therapy, for participants who become HIV infected during the course of the trial. There is
p.000047: also agreement that prevention trials ought to contribute constructively to the development of HIV service provision in

p.000048: The provision of antiretroviral treatment to trial participants who acquire HIV infection during the trial
p.000048: requires planning for logistics and implementation. Most such participants will not need antiretroviral treatment

p.000048: their priority list for access to antiretroviral treatment under the “Towards Universal Access” programme.
p.000048: Trial sponsors and researchers should collaborate with governments in low- and middle-income countries to
p.000048: explore,develop,and strengthen national and local capacity to deliver the highest possible level of HIV prevention,
p.000048: care, and treatment services through strategic investment and development of trial-related resources. In most
p.000048: situations, no one stakeholder should bear the entire burden of providing resources for such services and the central
p.000048: responsibility for delivery should lie with local health systems.
p.000048: Decisions on how these obligations are to be met are best made for each specific trial through a transparent and
p.000048: participatory process that should involve all research stakeholders before a trial starts to recruit participants (see
p.000048: Guidance Point 2). This process should explore options and determine the core obligations applicable to the given
p.000048: situation, in terms of the level, scope, and duration of the care and treatment package, equity in eligibility to
p.000048: access services, and responsibility for provision and delivery. Agreements on who will finance, deliver, and monitor
p.000048: care and treatment should be documented. All stakeholders should recognize that this is a critically important and

p.000049: conditions of both the trial participants and the community from which they are drawn, and support and to strengthen a
p.000049: country’s comprehensive response to the epidemic. Strengthening mechanisms to provide care, treatment, and support for

p.000049: A care and treatment package should include, but not be limited to, some or all of the following items, depending on

p.000050: Control Groups
p.000050:
p.000050: Participants in both the control arm and the intervention arm should receive all established effective HIV risk
p.000050: reduction measures. The use of a placebo control arm is ethically acceptable in a biomedical HIV prevention trial
p.000050: only when there is no HIV prevention modality of the type being studied that has been scientifically validated in
p.000050: comparable populations or approved by relevant authorities.
p.000050:
p.000050: Aside from male circumcision, a biomedical HIV prevention inter- vention with proven efficacy in preventing HIV
p.000050: acquisition or HIV- related disease does not currently exist. Therefore, until an effica- cious intervention is
p.000050: developed, the use of a placebo control arm could be ethically acceptable in appropriately designed protocols,
p.000050: such as three-arm trials. For example, there may be compelling scien- tific reasons which justify the use of a placebo
p.000050: rather than a known effective biomedical HIV intervention in the following instances:
p.000050: An effective HIV vaccine exists but it is not known to be effective against the virus that is prevalent in the research
p.000050: population.
p.000050: The biological conditions that prevailed during the initial trial demonstrating efficacy of a biomedical HIV prevention
p.000050: product are so different from the conditions in the proposed research population that the results of the initial trial
p.000050: are not generalizable and cannot be directly applied to the research population under consideration.
p.000050: A microbicide shown to be effective for vaginal intercourse may not be effective for rectal intercourse.
p.000050: Effectiveness of an intervention in one population may not be reproduced in the context of another population if the
p.000050: success of the intervention is strongly related to behaviour or behavioural modification and conditions of product
p.000050: utilisation. For example, a partially effective, coitally dependent microbicide evaluated among women in stable
p.000050: partnerships may not be generalizable to women with multiple casual partners.

p.000051: Informed Consent
p.000051:
p.000051: Each volunteer being screened for eligibility for participation in a biomedical HIV prevention trial should provide
p.000051: voluntary informed consent based on complete, accurate, and appropriately conveyed and understood information before
p.000051: s/he is actually enrolled in the trial. Researchers and research staff should take efforts to ensure
p.000051: throughout the trial that participants continue to understand and to participate freely as the trial progresses.
p.000051: Informed consent, with pre- and post-test counselling, should also be obtained for any testing for HIV status conducted
p.000051: before, during, and after the trial.
p.000051:
p.000051:
p.000051: Biomedical HIV prevention trials require informed consent for all components of participation at a number of stages.
p.000051: The first stage consists of screening candidates for eligibility for participation in the trial. The screening
p.000051: process involves interviews on personal matters, such as sexual behaviour and drug use, which are protected by a
p.000051: right to privacy. To guarantee this right, secrecy and confi- dentiality must be strictly observed and appropriate
p.000051: measures of personal data protection should be set in place (see Guidance Point 18). The screening process also
p.000051: involves medical tests (such as blood draws, pregnancy and HIV tests, vaginal examinations, and a general physical
p.000051: examination), the results of which are also private and should be kept in confidence. Informed consent should be
p.000051: obtained to undergo this screening process, based on a full divulgence of all material information regarding the
p.000051: screening procedures, as well as an outline of the biomedical HIV prevention trial in which they will be invited to
p.000051: enrol, if found eligible. Fully informed consent should also be given for the test for HIV status, which should be
p.000051: accompanied by pre-and post-test counselling and, if the result is HIV positive, referral to clinical and social
p.000051: support services.

p.000052:
p.000052:
p.000052: The second stage at which informed consent is required occurs once a person is judged eligible for enrolment. That
p.000052: individual should then be given full information concerning the nature and length of participation in the trial,
p.000052: including the risks and benefits posed by participation, so that s/he is able to give informed consent to participate.
p.000052: Time should be allowed to consider participation, discuss with others such as partners, and ask questions. Candidates
p.000052: should also be informed of their rights as participants, including the right to confidentiality (see Guidance Point
p.000052: 18) and the right to refuse to participate or to withdraw at any time from the study without penalty.
p.000052:
p.000052: Once enrolled, efforts should then be made throughout the trial to obtain assurance that the participation continues to
p.000052: be on the basis of free consent and understanding of what is happening. Informed consent, with pre- and post-test
p.000052: counselling, should also be given for any repeated tests for HIV status. Throughout all stages of the trial and consent
p.000052: process, there should be assurance by the investigator that the information is understood by the participant before
p.000052: consent is given. Informed consent is a process, not just a piece of paper to be read and signed. The information
p.000052: should be presented in appropriate forms and languages, including written information sheets. In addition, there
p.000052: should be oral communication of information, especially for participants who may be illiterate, and standardized tests
p.000052: for assessment of comprehension, where necessary.
p.000052:
p.000052: In addition to the standard content of informed consent prior to participation in a biomedical HIV preventive
p.000052: intervention trial, each prospective participant must be informed, using appropriate language and technique, of the
p.000052: following specific details:
p.000052:
p.000052: the reasons they have been chosen as prospective participants, including whether they are at higher risk of HIV
p.000052: exposure;
p.000052: that the biomedical HIV prevention product is experimental and it is not known that it will prevent HIV infection or
p.000052: disease, and

p.000053:
p.000053: further, when such is the case, that some of the participants will receive a placebo instead of the candidate HIV
p.000053: prevention product through random assignment;
p.000053: that they will receive counselling concerning how to reduce their risk of HIV exposure and access to risk-reduction
p.000053: means (in particular, male and female condoms, clean injecting equipment, and where relevant, male
p.000053: circumcision); and that, in spite of these risk-reduction efforts, some of the partici- pants may become
p.000053: infected, particularly in the case of phase III trials where large numbers of participants at higher risk of HIV
p.000053: exposure are participating;
p.000053: the specific risks for physical harm, as well as for psychological and social harm (see Guidance Point 11), the types
p.000053: of treatment and compensation that are available for harm, and the services to which they may be referred should harm
p.000053: occur;
p.000053: the nature and duration of care and treatment that is available, and how it can be accessed, if they become infected
p.000053: with HIV during the course of the trial (see Guidance Point 14);
p.000053: the collection, use, and period of storage of biological samples and specimens provided by participants, and the
p.000053: options for their disposal at the conclusion of the trial, including the option to refuse to allow use of such samples
p.000053: or specimens beyond the scope of the specific trial in which they have participated.
p.000053: the use, confidentiality, period of storage, and disposal of personal data including genetic information, including
p.000053: the option to refuse to allow use of such data beyond the scope of the specific trial in which they participated (see
p.000053: Guidance Point 18).
p.000053:
p.000053: Special Measures
p.000053: Researchers and research staff should take special measures to protect persons who are, or may be, limited in
p.000053: their ability to partic- ipate voluntarily in a biomedical HIV prevention trial due to their social or legal status.
p.000053: The presumption is that all adults are legally competent to give informed consent to participate in a biomed- ical HIV
p.000053: prevention trial. However, there are several categories of

p.000054: Ethical considerations in biomedical HIV prevention trials
p.000054:
p.000054:
p.000054: persons who are legally competent and who have sufficient cognitive capacity to consent, but who may have limitations
p.000054: in their freedom to make independent choices (see Guidance Point 8).
p.000054:
p.000054: The following are individuals or groups who should be given extra consideration with regard to their ability to
p.000054: voluntarily participate in biomedical HIV prevention trials:
p.000054: persons who are junior or subordinate members of hierarchical structures, who may be vulnerable to undue
p.000054: influence or coercion and may fear retaliation if they refuse cooperation with authorities, including members of the
p.000054: armed forces, students, government employees, prisoners, and refugees;
p.000054: persons who engage in illegal or socially stigmatised activities, who are vulnerable to undue influence and threats
p.000054: presented by possible breaches of confidentiality and action by law enforce- ment authorities, including sex workers,
p.000054: injecting drug users, and men who have sex with men;
p.000054: persons who are impoverished or dependent on welfare programmes, who are vulnerable to being unduly influenced
p.000054: by offers of what others may consider modest material or health inducements.
p.000054: Those who plan, review, and conduct biomedical HIV prevention trials should be alert to the problems presented by the
p.000054: involvement of such persons, and take appropriate steps to ensure meaningful and independent ongoing informed consent,
p.000054: and to respect their rights, foster their well being, and protect them from harm. Such steps would include community
p.000054: involvement in the design of recruitment and informed consent processes, along with the sensitization and training of
p.000054: research staff and counsellors on these issues.

p.000055: Monitoring Informed Consent and Interventions
p.000055:
p.000055: Before a trial commences, researchers, trial sponsors, countries, and communities should agree on a plan for
p.000055: monitoring the initial and continuing adequacy of the informed consent process and risk- reduction interventions,
p.000055: including counselling and access to proven HIV risk-reduction methods.
p.000055:
p.000055:
p.000055: Methods for monitoring the adequacy of recruitment and informed consent processes, including evaluation of
p.000055: participants’ comprehen- sion of information, should be designed and agreed upon by the community-
p.000055: government-investigator-sponsor partnership. The value of informed consent depends primarily on the ongoing quality of
p.000055: the process by which it is conducted and not solely on the structure and content of the informed consent document. The
p.000055: informed consent process should be designed and monitored to empower participants to allow them to make appropriate
p.000055: decisions about continuing or withdrawing from the study. Special attention should be given to ensure that individuals
p.000055: are aware of their right to withdraw from a trial without any penalty, and that they are actually free to do so.
p.000055: Similarly, there are many ways in which risk-reduction interventions (coun- selling and access to means of HIV
p.000055: prevention) can be conducted, with some methods being more effective than others in conveying the relevant information
p.000055: and in reducing risk of HIV exposure for different individuals and study populations.
p.000055:
p.000055: Monitoring should include quality assurance of gender- and culture- sensitive counselling services, appropriate
p.000055: procedures for adolescents, and evaluation of the impact of the trial on the vulnerabilities of the commu- nities
p.000055: involved in the study. It should also cover the welfare of partici- pants throughout the trial, including when
p.000055: discontinuing participation in case of adverse reactions, untoward events or changes in clinical status.

p.000056: Ethical considerations in biomedical HIV prevention trials
p.000056:
p.000056:
p.000056: Consideration should be given to expansion of the responsibilities of the clinical trial monitor to include adherence
p.000056: to the recruitment and informed consent processes and to counselling standards. Consideration could also be given to
p.000056: the appointment of an independent ombud- sperson who would handle any complaints from participants related to the
p.000056: conduct of the trial and suggest appropriate responses.
p.000056:
p.000056: The appropriateness of such plans should be determined by the scien- tific and ethical review committees that are
p.000056: responsible for providing prior and continuing review of the trial. This recommendation supplements the usual
p.000056: guidelines for the monitoring of biomedical HIV prevention trials for safety and compliance with scientific and ethical
p.000056: standards and regulatory requirements.
p.000056:
p.000056: Guidance Point 18:
p.000056: Confidentiality
p.000056:
p.000056: Researchers and research staff must ensure full respect for the entitlement of potential and enrolled
p.000056: participants to confidentiality of information disclosed or discovered in the recruitment and informed consent
p.000056: processes, and during conduct of the trial. Researchers have an ongoing obligation to participants to develop
p.000056: and implement procedures to maintain the confidentiality and security of information collected.
p.000056:
p.000056:
p.000056: A lot of information about a volunteer or a study participant is collected as part of participation in
p.000056: HIV vaccine and prevention research.Very personal information, like sexual behaviour, drug use, HIV status, medical
p.000056: conditions or even association with the trial could be highly stigmatizing and might be socially harmful if other
p.000056: people wrongly discover it. It is therefore of particular importance in biomedical HIV prevention trials that
p.000056: researchers and research staff commit to keeping confidential all personal information of all
p.000056:
p.000057: 57

p.000057: UNAIDS / WHO guidance document
p.000057:
p.000057:
p.000057: potential and enrolled participants so as to minimise the likelihood of such harm, and that they explain to volunteers
p.000057: and participants what measures they will be taking to protect privacy and personal informa- tion, and what limitations
p.000057: may exist on their ability to do so.
p.000057: All participants are entitled to confidentiality of information disclosed or discovered in the recruitment and informed
p.000057: consent processes, and during conduct of the trial. Community involvement should not compromise the confidentiality
p.000057: of study participants. This is of partic- ular importance with respect to participants from vulnerable popu- lations,
p.000057: women and adolescents, who may be socially susceptible to stigma and discrimination (see Guidance Points 8, 9, 10).
p.000057: There may be specific exceptions to the duty of confidentiality for legal or ethical reasons, but those exceptions
p.000057: should be prospectively identified and disclosed to the participant during the informed consent process.
p.000057: Legal exceptions to the duty to maintain confidentiality might exist, for example, where disclosure is mandated by a
p.000057: court order or where there is a duty to report to public health authorities. In the case of children and adolescents,
p.000057: reporting of abuse and neglect might be required under child protection laws. Similarly, the reporting of domestic
p.000057: violence might be a legal duty.Trial staff should be trained to identify instances where there is such a mandatory
p.000057: reporting duty.
p.000057: Breach of confidentiality might also be warranted on ethical grounds, so as to notify sexual partners. For example,
p.000057: where women participate in microbicide trials, there may be unknown risks of harm to male partners. The sponsor and
p.000057: researcher should have a mechanism for them to come forward to report possible negative consequences and make sure that
p.000057: they are notified of such, preferably by the female participants. Likewise, when participants become HIV positive,
p.000057: sexual partners at ongoing risk should be notified for referral to testing programmes and treatment facilities.
p.000057: However, researchers and research staff should be sensitive to the possibility of domestic violence as a result of
p.000057: partner notification.
p.000057: Researchers have an ongoing obligation to participants and the host community to develop and implement
p.000057: procedures to protect

p.000058:
p.000058: the privacy of participants and to maintain the confidentiality of information collected. Such procedures might include
p.000058: interviewing participants outside, where they cannot be overheard, or permitting participants to not receive HIV test
p.000058: results. Both health care workers and research staff may need explicit training on how to maintain confidentiality. To
p.000058: protect confidentiality, workers in the clinic or programme setting where recruitment is taking place should first ask
p.000058: potential volunteers whether they would be willing to speak to a researcher who will provide information about trial
p.000058: participation. In the case of adolescents being recruited for endpoint efficacy trials, researchers should inquire
p.000058: whether their parents are aware of their sexual behaviour and explain that parental permission will be required for
p.000058: enrolment. In the case of media interest in the trial, research staff members should also advise participants of
p.000058: possible negative impact that may result from public exposure. Community advisory boards may need training to enable
p.000058: members to interview about the trial in ways that do not compromise the duty of confidentiality owed to individual
p.000058: participants or jeopardise their right to privacy.
p.000058: Research may involve collecting and storing private and sensitive data relating to individuals and communities
p.000058: including data derived from biological samples (see Guidance Point 16). Measures of data protection are of major
p.000058: importance in large-scale studies such as HIV prevention trials which establish large databases to integrate clinical
p.000058: data and monitor public health effect. Decisions regarding which personal data are to be collected and stored must be
p.000058: based on the requirements of the trial design and the medical needs of participants. Personal identifiable data should
p.000058: be collected only by people who have signed a confidentiality agreement. The collection of personal identifiable data
p.000058: should be kept at a minimum and such data should not be stored longer than necessary. Procedures should be in place to
p.000058: monitor the use of the system where the data are stored in order to detect potential or actual security threats.
p.000058: Systematic guidance on security of data can be found in the UNAIDS Interim Guidelines on Protecting the Confidentiality
p.000058: and Security of HIV Information (2007).

p.000059: Availability of Outcomes
p.000059:
p.000059: Researchers should inform trial participants and their communities of the trial results. During the initial
p.000059: stages of development of a biomedical HIV prevention trial, trial sponsors and countries should agree on
p.000059: responsibilities and plans to make available as soon as possible any biomedical HIV preventive intervention
p.000059: demonstrated to be safe and effective, along with other knowledge and benefits helping to strengthen HIV prevention, to
p.000059: all participants in the trials in which it was tested, as well as to other populations at higher risk of HIV exposure
p.000059: in the country.
p.000059:
p.000059: To respect and recognize the contribution of trial participants and their communities to clinical research, researchers
p.000059: should inform them of the trial results, whether the biomedical intervention does or does not demonstrate efficacy, or
p.000059: the trial is stopped prematurely. Once a trial product has proven safe and effective, sponsors and researchers should
p.000059: work with development partners, national governments, local authori- ties, and industry where relevant, to ensure
p.000059: planning for its manufac- turing, regulatory approval, fair distribution, and efficient delivery in the community
p.000059: engaged in the trial and the country.
p.000059:
p.000059: Given the severity of the HIV epidemic, it is imperative that suffi- cient incentives exist, both through financial
p.000059: rewards in the market- place and through public subsidies, to foster development of safe and effective biomedical HIV
p.000059: prevention products and ensure that they are produced and made readily and affordably available to the communities and
p.000059: countries where a product is tested, as well as to populations at higher risk of HIV exposure in other countries.

p.000060: research available to that population. Critics contend that it is pater- nalistic to specify the benefits, and that the
p.000060: country may identify other benefits that have a higher priority. However, given the severity of the epidemic (see
p.000060: Guidance Point 1) making a successful HIV biomedical HIV prevention product or intervention reasonably available to the
p.000060: population where it was tested can be sustained as a basic ethical requirement.
p.000060:
p.000060: Health and research communities building biomedical HIV preven- tion product development programmes should initiate
p.000060: before trials commence, and carry on through the course of the research, a process of discussion and
p.000060: negotiation about how products will be made available, along with other benefits resulting from the research, if the
p.000060: HIV preventive intervention is effective.This discussion should include representatives from relevant country
p.000060: stakeholders, such as representatives from the executive branch, health ministry, local health authorities, and
p.000060: relevant scientific and ethical groups, as well as from community advisory mechanisms and other key stakeholders. It
p.000060: should address issues such as payments, royalties, subsidies, technology and intellectual property, as well as
p.000060: distribution costs, channels and modalities, including delivery strategies, target populations, demand estimates, and
p.000060: supply chain requirements.

p.000062: People Who Inject Drugs6
p.000062:
p.000062: Researchers and sponsors should include people who inject drugs in biomedical HIV prevention trials in order to verify
p.000062: safety, efficacy, and effectiveness from their standpoint, including immunogenicity in the case of vaccines.7 As with
p.000062: other key populations at higher risk of HIV exposure, providing people who inject drugs with access to proven,
p.000062: effective HIV preventive interventions is a public health imperative. Researchers and trial sponsors should engage
p.000062: meaningfully with people who inject drugs and with other stakeholders to overcome the complex legal, ethical,
p.000062: and regulatory challenges to the participation in biomedical HIV prevention trials of people who inject
p.000062: drugs. Trial conduct that is ethical is informed by the latest scientific evidence on proven HIV prevention strategies
p.000062: and ensures that participants’ human rights, safety, and welfare are protected.
p.000062:
p.000062: People who inject drugs are at higher risk of acquiring blood-borne HIV infection, primarily because legal and
p.000062: logistical barriers impede safer use and access to sterile injecting equipment, such as needles, syringes, and
p.000062: cookers.They are also at increased risk of acquiring and transmitting HIV through unsafe sexual practices.Women who
p.000062: inject drugs or who have a partner who injects drugs are at higher risk of HIV acquisition and of subsequent
p.000062: mother-to-child transmission during pregnancy, labour and delivery, and breastfeeding.
p.000062:
p.000062: As with other key populations at higher risk of HIV acquisition, people who inject drugs should be included and
p.000062: meaningfully engaged (see Guidance Point 2) in biomedical HIV prevention trials
p.000062:
p.000062: 6 A broader term that may apply is ‘people who use drugs’ when such use places individuals at higher risk of
p.000062: HIV exposure through non-injecting modes of transmission.
p.000062: 7 As for all the guidance points in this document, this guidance point is relevant to trials of various behavioural
p.000062: HIV prevention methods and structural interventions.

p.000063: in order to ensure that novel prevention methods are proven to be safe, efficacious, and accessible for them, both as a
p.000063: matter of equity and as an expression of their right to health. However, prevention trials involving people who inject
p.000063: drugs pose complex challenges that may increase risks to trial participants. Researchers and sponsors should take
p.000063: necessary steps to safeguard participants’ human rights, safety, and welfare.
p.000063:
p.000063: The ethical principles of beneficence and non-maleficence obligate researchers and sponsors to maximize benefits and
p.000063: minimize risks to participants in HIV clinical trials. This is done in part by providing appropriate counselling and
p.000063: facilitating access to proven state-of-the- art risk reduction methods (see Guidance Point 13). However, legal
p.000063: barriers, punitive law enforcement practices, logistical challenges, and discrimination often prevent people who inject
p.000063: drugs from accessing proven risk reduction methods, including those comprising the comprehensive package of core
p.000063: interventions for people who inject drugs developed by WHO, UNODC, and UNAIDS.8 In addition to provision of condoms,
p.000063: counselling, and access to educational infor- mation on safe-injecting practices, a key risk reduction method for
p.000063: people who inject drugs is the use of sterile injecting equipment. Where there are insurmountable barriers to ensuring
p.000063: access to sterile needles and syringes for all trial participants, HIV prevention trials among people who inject drugs
p.000063: should not proceed.
p.000063:

p.000063: programmes with condom for people who inject drugs and their sexual partners; targeted information, education, and

p.000064: biomedical HIV modality being tested (see Guidance Point 13).
p.000064:
p.000064: In settings where possession of injecting equipment is illegal, researchers and sponsors should negotiate
p.000064: agreements with relevant authorities so that risk reduction tools provided through the trial as standard of prevention
p.000064: do not increase the risk that trial participants will be subject to punitive legal or extra-legal enforcement measures.
p.000064: Some potential risk reduction interventions,for example opioid substi- tution treatment, may carry additional risks for
p.000064: trial participants, such as breaches of privacy and confidentiality resulting from mandatory registration. Further,
p.000064: painful opioid withdrawal may result if medica- tion-assisted substitution programmes are not properly resourced and
p.000064: sustained. Trial sponsors, researchers, and advocates should continue efforts to determine whether and how risks
p.000064: associated with compo- nents of the risk reduction package could be mitigated in both the short- and long-term.
p.000064:
p.000064: Researchers and sponsors have an obligation to ensure access to HIV care and treatment, including antiretroviral
p.000064: therapy, for participants who acquire HIV infection during a trial (see Guidance Point 14). In addition, they should
p.000064: negotiate with national and local governments appropriate referral mechanisms to ensure access to care and treatment
p.000064: for those people who volunteer to participate in a trial but who are screened out as ineligible when they are found to
p.000064: be HIV-positive. In some settings, people who inject drugs may not be seen as priority recipients for limited HIV care
p.000064: and treatment resources. The ethical principle of justice requires both that researchers and sponsors work to ensure
p.000064: that access to care and treatment is available to people who inject drugs as equitably as it is to others in the
p.000064: community and that the standard of care and treatment is equivalent across high-, low- and middle-income countries (See
p.000064: Guidance Point 14). Care for trial participants may also involve the treatment of co-morbidities, ready

p.000065: access to overdose management, and provision of a safe place of respite where participants may be provided with food or
p.000065: other amenities. A transparent and inclusive process to determine logistics and to assign responsibilities for
p.000065: providing this care package should take place in advance of trial commencement.
p.000065:
p.000065: People who inject drugs suffer several layers of vulnerability (see Guidance Point 8). Criminalization of their drug
p.000065: use renders them vulnerable to punitive, often harsh, law enforcement practices including incarceration.They may
p.000065: experience additional vulnerability because of generalized stigma and discrimination, including from some health
p.000065: care professionals and policy-makers; personal mental health issues, preceding or resulting from their drug use;
p.000065: poverty; racism, if they are members of certain racially-defined groups; and marginalization. Gender adds an additional
p.000065: layer of vulnerability for people who inject drugs who are women, men who have sex with men, or people who are
p.000065: transgender or intersex. They may experi- ence increased vulnerability to unprotected sex and unsafe injections,
p.000065: exploitation, discrimination, lack of sensitivity to their specific needs, and under-resourcing of services to meet
p.000065: their needs.
p.000065:
p.000065: Prior to commencing a trial, researchers and sponsors should conduct formative research to gain understanding of
p.000065: particular contextual challenges and vulnerabilities that people who inject drugs face and to begin building
p.000065: trust with people who inject drugs and their networks. The research protocol should describe the vulnerabilities
p.000065: identified, as well as steps that have been or will be taken to create a safe enabling environment for trial
p.000065: participants. HIV prevention trials should not be conducted where there are insurmountable barriers to ensure safety,
p.000065: protection, and confidentiality of trial participants (see Guidance Point 18). For this reason, and because adherence
p.000065: to the principle of autonomy cannot be guaranteed, HIV prevention trials should not be conducted in compulsory drug
p.000065: detention centres.

p.000066:
p.000066: In many settings around the world, the consequences of being identi- fied as a person who injects drugs are extremely
p.000066: serious. Precautions should be taken to ensure that recruitment and retention are voluntary, and that people’s
p.000066: right to confidentiality and privacy is not breached (see Guidance Point 18). Recruitment within voluntary drug
p.000066: treatment centres, especially by service providers upon whom people who inject drugs are dependent for on-going
p.000066: care, may pose special problems regarding voluntariness of trial participation. Generally, potential trial
p.000066: participants should not be recruited by their service providers. Where respondent-driven recruitment and other
p.000066: snowball-type recruitment techniques are used, confidenti- ality should be emphasized to recruiters. Research teams
p.000066: should be trained to identify when a potential participant is unable to make a voluntary, informed decision about trial
p.000066: participation. Being under the influence may alone not be sufficient reason to assume lack of capacity to decide.
p.000066: Participants should be clearly informed of any limits to confidentiality to which researchers are bound by regulation.
p.000066:
p.000066: It is not uncommon for people who inject drugs to be incarcerated because of their drug use or for peripheral reasons
...

p.000066: procedures for voluntary withdrawal of the participant from the trial. The protocol should address confidentiality
p.000066: and voluntariness, access to risk reduction measures while incarcerated, access to a physician, and post-release
p.000066: planning including for consent to re-join the trial. In particular, mechanisms should be put in place to ensure
p.000066: that there is no inter- ruption of antiretroviral therapy or opioid substitution treatment. All relevant stakeholders,
p.000066: including prison authorities, should agree to these provisions in advance of a trial.

p.000067: In choosing the form of reimbursement for travel and other expenses related to trial participation (see Guidance
p.000067: Point 12), researchers should take into consideration participants’ preferences and local conditions in order to
p.000067: reach an agreement upon the form and amount of reimbursement. Based on the principle of non-maleficence and concern for
p.000067: undue inducement, caution should be applied when using cash compensations in all clinical trials9. Assuming that
p.000067: partici- pants who inject drugs should be provided only with vouchers or in-kind compensation, rather than cash
p.000067: reimbursement equivalent to that provided in trials involving other populations, is discriminatory.
p.000067:
p.000067: When the biomedical HIV prevention product or intervention tested in a trial is proven to be safe and efficacious,
p.000067: provision should be made to offer it to all trial participants, and to the communities from which they are drawn,
p.000067: following trial completion, regulatory approval, and licencing (see Guidance Point 19).

p.000043: Some have contended that to promise antiretroviral treatment to HIV prevention trial participants who become infected
p.000043: would constitute an undue inducement to participate in the trial. That supposition is most unlikely, since biomedical
p.000043: HIV prevention trials enrol healthy people, not individuals who are already sick and need treatment. If anything, the
p.000043: possibility of being protected from acquiring HIV by the preventive method itself could conceivably be considered an
p.000043: undue inducement; however, if that were the case, clinical trials of preven- tive methods could never be ethically
p.000043: carried out. Concerns that any form of care and treatment promised to participants in research on biomedical HIV

p.000057: All participants are entitled to confidentiality of information disclosed or discovered in the recruitment and informed

p.000057: There may be specific exceptions to the duty of confidentiality for legal or ethical reasons, but those exceptions
p.000057: should be prospectively identified and disclosed to the participant during the informed consent process.
p.000057: Legal exceptions to the duty to maintain confidentiality might exist, for example, where disclosure is mandated by a

p.000058: potential volunteers whether they would be willing to speak to a researcher who will provide information about trial

p.000032: Women throughout the life span, including those who are sexually active and may become pregnant, be pregnant or be

p.000032: should be eligible for enrolment in biomedical HIV prevention trials, both as a matter of equity and because in many
p.000032: communities throughout the world women, particularly young women, are at higher risk of HIV exposure.
p.000032: Therefore, the efficacy of candidate biomedical HIV prevention products, and their immunogenicity in the case of

p.000033: should be discussed and resolved on a case-by-case basis early on in the planning of the research design. In any event,

p.000033:
p.000033: The most notable data gap in the evaluation of some prevention methods, particularly in phase I and II trials, is
p.000033: adequate evaluation of safety and efficacy among women. Barriers for women partici- pating in trials include
p.000033: contraceptive requirements, issues related to current or future fertility, concerns about safety for the foetus, and
p.000033: fear of being labelled as being at higher risk for HIV exposure. Also, women present issues of particular complexity
p.000033: with regard to recruitment and informed consent. In some cultures, women and girl adolescents may not be able to
p.000033: exercise true autonomy in light of the influence of their parents or sexual partners (see Guidance Point 7). In others,
p.000033: young people may be more informed than their parents, and their view and their parents’ or partners’ views on
p.000033: their participation may differ. Further, the need for HIV testing or pregnancy testing to assess eligibility for
p.000033: inclusion in a trial may raise difficult issues regarding the maintenance of appropriate confi- dentiality.
p.000033: Researchers and research staff should improve recruit- ment strategies by anticipating and finding solutions to
p.000033: address and overcome these barriers (see Guidance Point 7). Appropriate reproductive and sexual health counselling
p.000033: and ancillary services, including family planning, should be provided to trial participants.

p.000035: their standpoint, in addition to immunogenicity in the case of vaccines, since they should be recipients of
p.000035: future biomedical HIV preventive interventions. Researchers, trial sponsors, and countries should make

p.000035:
p.000035: Children3 , including infants and adolescents, should be eligible for enrolment in biomedical HIV preventive
p.000035: intervention trials, both as a matter of equity and because in many communities throughout the world children are at a
p.000035: higher risk of HIV exposure. Infants born to HIV-infected mothers are at risk of becoming infected during birth and
p.000035: during the postpartum period through breastfeeding. Many adolescents are also at higher risk of HIV infection due to
p.000035: sexual activity, lack of access to HIV prevention education and means, and through injecting drugs with non-sterile
p.000035: equipment.
p.000035:

p.000005: Well into the third decade of the HIV pandemic, there remains no effective HIV preventive vaccine, microbicide, product

p.000008: and communities. They have an urgent need for additional HIV prevention choices for use at various stages of the
p.000008: life-cycle, a need to have their rights protected and their welfare promoted in the context of the development and
p.000008: testing of novel HIV prevention modalities, and a need to be able to participate fully as equal partici- pants in the
p.000008: research process. These factors include the following:
p.000008: The global burden of disease and death related to HIV continues to increase at a rate unmatched by any other pathogen.
p.000008: For many countries, AIDS is the leading cause of death. Currently available treatments do not lead to cure, but
p.000008: do slow the progression of disease.The most effective treatment for slowing HIV-related disease progression,
p.000008: antiretroviral medication, is a life-long treatment which requires close medical monitoring, is still very costly,
p.000008: especially for 2nd line regimens, and can cause significant adverse effects. Because of this, antiretroviral medi-
p.000008: cation is not readily available to the vast majority of people living with HIV who need it. More than 2 million people
p.000008: had access to antiretroviral treatments in low- and middle-income countries in 2006, five times more people than in
p.000008: 2003. But despite this tremendous progress in the roll-out of antiretroviral treatment, global coverage of needs is
p.000008: below 30%.
p.000008: For every person placed on antiretroviral treatment in 2006, another six people became newly infected with HIV. There
p.000008: is therefore an ethical imperative to seek, as urgently as possible, effective and accessible biomedical HIV prevention

p.000035:
p.000035: Children3 , including infants and adolescents, should be eligible for enrolment in biomedical HIV preventive
p.000035: intervention trials, both as a matter of equity and because in many communities throughout the world children are at a
p.000035: higher risk of HIV exposure. Infants born to HIV-infected mothers are at risk of becoming infected during birth and
p.000035: during the postpartum period through breastfeeding. Many adolescents are also at higher risk of HIV infection due to

p.000043:
p.000043: Some have contended that to promise antiretroviral treatment to HIV prevention trial participants who become infected
p.000043: would constitute an undue inducement to participate in the trial. That supposition is most unlikely, since biomedical
p.000043: HIV prevention trials enrol healthy people, not individuals who are already sick and need treatment. If anything, the
p.000043: possibility of being protected from acquiring HIV by the preventive method itself could conceivably be considered an
p.000043: undue inducement; however, if that were the case, clinical trials of preven- tive methods could never be ethically
p.000043: carried out. Concerns that any form of care and treatment promised to participants in research on biomedical HIV
p.000043: preventive interventions could be an undue induce- ment are unwarranted.
p.000043:
p.000043: Some may argue that provision of state-of-the-art prevention, care, and treatment services for participants introduces
p.000043: local inequalities and is therefore unjust when non-participants do not receive those services. However, all scale-up
p.000043: programmes involve temporary inequalities in the community until universal access can be attained. Achieving a perfect
p.000043: system of equal justice is a long-term process.

p.000047:
p.000047: Participants who acquire HIV infection during the conduct of a biomedical HIV prevention trial should be
p.000047: provided access to treatment regimens from among those internationally recognised as optimal. Prior to initiation of
p.000047: a trial, all research stakeholders should come to agreement through participatory processes on mechanisms to provide

p.000047:
p.000047: The obligation on the part of sponsors and investigators to ensure access to HIV care and treatment, including
p.000047: antiretroviral treatment, for participants who become infected derives from some or all of three ethical principles.
p.000047: The principle of beneficence requires that the welfare of participants be actively promoted. The principle of justice
p.000047: as reciprocity calls for providing something in return to participants who have volunteered their time, been
p.000047: inconvenienced or experi- enced discomfort by enrolling in the trial. The principle of justice, meaning treating like
p.000047: cases alike, requires that trial participants in high- income and low- and middle-income countries be treated equally
p.000047: regarding access to treatment and care.
p.000047: A consensus on the level of care and treatment that should be provided to trial participants has emerged in
p.000047: recent years with increasing accessibility of antiretroviral treatment in low- and middle-income countries, based on
p.000047: strong commitments from countries, development partners and multilateral organizations; dramatic decreases in drug
p.000047: prices; and evidence that treatment programmes in resource-poor settings are feasible and sustainable. There is
p.000047: consensus that sponsors need to ensure access to internationally recognised optimal care and treatment regimens,
p.000047: including antiretroviral therapy, for participants who become HIV infected during the course of the trial. There is
p.000047: also agreement that prevention trials ought to contribute constructively to the development of HIV service provision in

p.000048: The provision of antiretroviral treatment to trial participants who acquire HIV infection during the trial

p.000048: Decisions on how these obligations are to be met are best made for each specific trial through a transparent and
p.000048: participatory process that should involve all research stakeholders before a trial starts to recruit participants (see

p.000055: Monitoring Informed Consent and Interventions
p.000055:
p.000055: Before a trial commences, researchers, trial sponsors, countries, and communities should agree on a plan for
p.000055: monitoring the initial and continuing adequacy of the informed consent process and risk- reduction interventions,
p.000055: including counselling and access to proven HIV risk-reduction methods.
p.000055:
p.000055:
p.000055: Methods for monitoring the adequacy of recruitment and informed consent processes, including evaluation of
p.000055: participants’ comprehen- sion of information, should be designed and agreed upon by the community-
p.000055: government-investigator-sponsor partnership. The value of informed consent depends primarily on the ongoing quality of
p.000055: the process by which it is conducted and not solely on the structure and content of the informed consent document. The
p.000055: informed consent process should be designed and monitored to empower participants to allow them to make appropriate
p.000055: decisions about continuing or withdrawing from the study. Special attention should be given to ensure that individuals
p.000055: are aware of their right to withdraw from a trial without any penalty, and that they are actually free to do so.
p.000055: Similarly, there are many ways in which risk-reduction interventions (coun- selling and access to means of HIV
p.000055: prevention) can be conducted, with some methods being more effective than others in conveying the relevant information
p.000055: and in reducing risk of HIV exposure for different individuals and study populations.
p.000055:
p.000055: Monitoring should include quality assurance of gender- and culture- sensitive counselling services, appropriate
p.000055: procedures for adolescents, and evaluation of the impact of the trial on the vulnerabilities of the commu- nities
p.000055: involved in the study. It should also cover the welfare of partici- pants throughout the trial, including when

p.000062: People Who Inject Drugs6
p.000062:
p.000062: Researchers and sponsors should include people who inject drugs in biomedical HIV prevention trials in order to verify
p.000062: safety, efficacy, and effectiveness from their standpoint, including immunogenicity in the case of vaccines.7 As with
p.000062: other key populations at higher risk of HIV exposure, providing people who inject drugs with access to proven,
p.000062: effective HIV preventive interventions is a public health imperative. Researchers and trial sponsors should engage
p.000062: meaningfully with people who inject drugs and with other stakeholders to overcome the complex legal, ethical,
p.000062: and regulatory challenges to the participation in biomedical HIV prevention trials of people who inject
p.000062: drugs. Trial conduct that is ethical is informed by the latest scientific evidence on proven HIV prevention strategies
p.000062: and ensures that participants’ human rights, safety, and welfare are protected.
p.000062:
p.000062: People who inject drugs are at higher risk of acquiring blood-borne HIV infection, primarily because legal and
p.000062: logistical barriers impede safer use and access to sterile injecting equipment, such as needles, syringes, and
p.000062: cookers.They are also at increased risk of acquiring and transmitting HIV through unsafe sexual practices.Women who
p.000062: inject drugs or who have a partner who injects drugs are at higher risk of HIV acquisition and of subsequent
p.000062: mother-to-child transmission during pregnancy, labour and delivery, and breastfeeding.
p.000062:
p.000062: As with other key populations at higher risk of HIV acquisition, people who inject drugs should be included and
p.000062: meaningfully engaged (see Guidance Point 2) in biomedical HIV prevention trials
p.000062:
p.000062: 6 A broader term that may apply is ‘people who use drugs’ when such use places individuals at higher risk of
p.000062: HIV exposure through non-injecting modes of transmission.

p.000063: in order to ensure that novel prevention methods are proven to be safe, efficacious, and accessible for them, both as a
p.000063: matter of equity and as an expression of their right to health. However, prevention trials involving people who inject
p.000063: drugs pose complex challenges that may increase risks to trial participants. Researchers and sponsors should take
p.000063: necessary steps to safeguard participants’ human rights, safety, and welfare.
p.000063:
p.000063: The ethical principles of beneficence and non-maleficence obligate researchers and sponsors to maximize benefits and
p.000063: minimize risks to participants in HIV clinical trials. This is done in part by providing appropriate counselling and
p.000063: facilitating access to proven state-of-the- art risk reduction methods (see Guidance Point 13). However, legal
p.000063: barriers, punitive law enforcement practices, logistical challenges, and discrimination often prevent people who inject
p.000063: drugs from accessing proven risk reduction methods, including those comprising the comprehensive package of core
p.000063: interventions for people who inject drugs developed by WHO, UNODC, and UNAIDS.8 In addition to provision of condoms,
p.000063: counselling, and access to educational infor- mation on safe-injecting practices, a key risk reduction method for
p.000063: people who inject drugs is the use of sterile injecting equipment. Where there are insurmountable barriers to ensuring
p.000063: access to sterile needles and syringes for all trial participants, HIV prevention trials among people who inject drugs
p.000063: should not proceed.

p.000064: In settings where possession of injecting equipment is illegal, researchers and sponsors should negotiate

p.000064: do not increase the risk that trial participants will be subject to punitive legal or extra-legal enforcement measures.
p.000064: Some potential risk reduction interventions,for example opioid substi- tution treatment, may carry additional risks for
p.000064: trial participants, such as breaches of privacy and confidentiality resulting from mandatory registration. Further,
p.000064: painful opioid withdrawal may result if medica- tion-assisted substitution programmes are not properly resourced and
p.000064: sustained. Trial sponsors, researchers, and advocates should continue efforts to determine whether and how risks
p.000064: associated with compo- nents of the risk reduction package could be mitigated in both the short- and long-term.
p.000064:
p.000064: Researchers and sponsors have an obligation to ensure access to HIV care and treatment, including antiretroviral
p.000064: therapy, for participants who acquire HIV infection during a trial (see Guidance Point 14). In addition, they should
p.000064: negotiate with national and local governments appropriate referral mechanisms to ensure access to care and treatment
p.000064: for those people who volunteer to participate in a trial but who are screened out as ineligible when they are found to
p.000064: be HIV-positive. In some settings, people who inject drugs may not be seen as priority recipients for limited HIV care
p.000064: and treatment resources. The ethical principle of justice requires both that researchers and sponsors work to ensure
p.000064: that access to care and treatment is available to people who inject drugs as equitably as it is to others in the
p.000064: community and that the standard of care and treatment is equivalent across high-, low- and middle-income countries (See
p.000064: Guidance Point 14). Care for trial participants may also involve the treatment of co-morbidities, ready

p.000065: providing this care package should take place in advance of trial commencement.
p.000065:
p.000065: People who inject drugs suffer several layers of vulnerability (see Guidance Point 8). Criminalization of their drug

p.000066: care, may pose special problems regarding voluntariness of trial participation. Generally, potential trial
p.000066: participants should not be recruited by their service providers. Where respondent-driven recruitment and other
p.000066: snowball-type recruitment techniques are used, confidenti- ality should be emphasized to recruiters. Research teams
p.000066: should be trained to identify when a potential participant is unable to make a voluntary, informed decision about trial
p.000066: participation. Being under the influence may alone not be sufficient reason to assume lack of capacity to decide.
p.000066: Participants should be clearly informed of any limits to confidentiality to which researchers are bound by regulation.
p.000066:
p.000066: It is not uncommon for people who inject drugs to be incarcerated because of their drug use or for peripheral reasons
p.000066: such as sex work, theft, and vagrancy. Researchers should anticipate that some trial participants could be
p.000066: incarcerated during the course of the trial and should develop an incarceration protocol describing the conditions to
p.000066: be followed to ensure that on-going ethical trial participation is preserved.This should include an option and
p.000066: procedures for voluntary withdrawal of the participant from the trial. The protocol should address confidentiality
p.000066: and voluntariness, access to risk reduction measures while incarcerated, access to a physician, and post-release
p.000066: planning including for consent to re-join the trial. In particular, mechanisms should be put in place to ensure
p.000066: that there is no inter- ruption of antiretroviral therapy or opioid substitution treatment. All relevant stakeholders,
p.000066: including prison authorities, should agree to these provisions in advance of a trial.

p.000067: In choosing the form of reimbursement for travel and other expenses related to trial participation (see Guidance
p.000067: Point 12), researchers should take into consideration participants’ preferences and local conditions in order to
p.000067: reach an agreement upon the form and amount of reimbursement. Based on the principle of non-maleficence and concern for
p.000067: undue inducement, caution should be applied when using cash compensations in all clinical trials9. Assuming that
p.000067: partici- pants who inject drugs should be provided only with vouchers or in-kind compensation, rather than cash

p.000029: elder or head of a family, in order for investigators to enter the community or to approach individuals. However, the
p.000029: third party only gives permission to invite individuals to participate and such authorisation or influence must not be

p.000029: a trial. In cases where it is proposed that minors will be enrolled as research participants, specific and full
p.000029: justification for their enrolment must be given, and their own assent or consent must be obtained in light of their

p.000031: Decision-making around conducting a biomedical HIV prevention trial needs to consider in what ways the trial might
p.000031: increase or decrease vulnerabilities. On the one hand, a trial might increase a participant’s risk of exposure to
p.000031: stigmatisation and discrimination if it highlights a population’s increased vulnerability to HIV exposure. On the
p.000031: other hand, a trial might decrease vulnerability, if it empowers the community or provides tangible assistance to
p.000031: participants, for example by improving the accessibility, affordability, and quality of appropriate healthcare
p.000031: services in the community. A social and political analysis should be carried out early on in planning the research
p.000031: process, to assess determi- nants of vulnerability, such as poverty, gender, age, ethnicity, sexuality, health,
p.000031: employment, education, and legal conditions in potential partic- ipating communities. Findings from this analysis
p.000031: should inform the design of research protocols, which should be sensitive to emerging information on incidental risks
p.000031: of social harm throughout the course of a trial. Research protocols might also include ongoing independent monitoring
p.000031: of a trial in relation to its impact on the vulnerabilities of communities participating in the study (see Guidance
p.000031: Point 17).
p.000031: The particular aspects of a social context that create conditions for exploi- tation or increased vulnerability should
p.000031: be described in the research protocol, as should the safeguards and measures that will be taken to prevent and overcome
p.000031: them. In some potential research populations (countries or communities), conditions affecting potential vulnerability
p.000031: or exploitation may be so severe that the risk outweighs the benefit of conducting the study in that population. In

p.000009: regions and countries. The relevance of these sub-types to probabilities of HIV transmission and acquisition, speed of
p.000009: disease progression and potential protection is not clearly understood.
p.000009: For the conduct of efficacy trials of any biomedical HIV prevention product, the populations with the highest
p.000009: incidence of HIV will be those most likely to be considered for participa- tion and would be those most likely to
p.000009: benefit from an effective intervention. However, for a variety of reasons, these popula- tions may be relatively
p.000009: vulnerable to exploitation and harm in the context of biomedical HIV prevention trials.Trial sponsors, countries,
p.000009: researchers, research staff and community leaders must make additional efforts to overcome this vulnerability.
p.000009: In some biomedical HIV prevention trials, individuals other than the trial participants may experience risks if they
p.000009: are exposed to the experimental product and may experience benefits if the product is effective. For example in trials
p.000009: of prophylaxis of mother-to-child transmission, the foetus is exposed to the prophylactic antiretroviral regimen in
p.000009: addition to the mother. If the mother develops antiretroviral resistance, she may transmit resistant virus to the
p.000009: infant. When the intervention is effective, the newborn baby is protected. In trials of vaginal microbicides, male

p.000057: may exist on their ability to do so.
p.000057: All participants are entitled to confidentiality of information disclosed or discovered in the recruitment and informed
p.000057: consent processes, and during conduct of the trial. Community involvement should not compromise the confidentiality
p.000057: of study participants. This is of partic- ular importance with respect to participants from vulnerable popu- lations,
p.000057: women and adolescents, who may be socially susceptible to stigma and discrimination (see Guidance Points 8, 9, 10).
p.000057: There may be specific exceptions to the duty of confidentiality for legal or ethical reasons, but those exceptions
p.000057: should be prospectively identified and disclosed to the participant during the informed consent process.
p.000057: Legal exceptions to the duty to maintain confidentiality might exist, for example, where disclosure is mandated by a
p.000057: court order or where there is a duty to report to public health authorities. In the case of children and adolescents,
p.000057: reporting of abuse and neglect might be required under child protection laws. Similarly, the reporting of domestic
p.000057: violence might be a legal duty.Trial staff should be trained to identify instances where there is such a mandatory
p.000057: reporting duty.
p.000057: Breach of confidentiality might also be warranted on ethical grounds, so as to notify sexual partners. For example,
p.000057: where women participate in microbicide trials, there may be unknown risks of harm to male partners. The sponsor and
p.000057: researcher should have a mechanism for them to come forward to report possible negative consequences and make sure that
p.000057: they are notified of such, preferably by the female participants. Likewise, when participants become HIV positive,
p.000057: sexual partners at ongoing risk should be notified for referral to testing programmes and treatment facilities.
p.000057: However, researchers and research staff should be sensitive to the possibility of domestic violence as a result of

p.000062: Researchers and sponsors should include people who inject drugs in biomedical HIV prevention trials in order to verify
p.000062: safety, efficacy, and effectiveness from their standpoint, including immunogenicity in the case of vaccines.7 As with
p.000062: other key populations at higher risk of HIV exposure, providing people who inject drugs with access to proven,
p.000062: effective HIV preventive interventions is a public health imperative. Researchers and trial sponsors should engage
p.000062: meaningfully with people who inject drugs and with other stakeholders to overcome the complex legal, ethical,
p.000062: and regulatory challenges to the participation in biomedical HIV prevention trials of people who inject
p.000062: drugs. Trial conduct that is ethical is informed by the latest scientific evidence on proven HIV prevention strategies
p.000062: and ensures that participants’ human rights, safety, and welfare are protected.
p.000062:
p.000062: People who inject drugs are at higher risk of acquiring blood-borne HIV infection, primarily because legal and
p.000062: logistical barriers impede safer use and access to sterile injecting equipment, such as needles, syringes, and
p.000062: cookers.They are also at increased risk of acquiring and transmitting HIV through unsafe sexual practices.Women who
p.000062: inject drugs or who have a partner who injects drugs are at higher risk of HIV acquisition and of subsequent
p.000062: mother-to-child transmission during pregnancy, labour and delivery, and breastfeeding.
p.000062:
p.000062: As with other key populations at higher risk of HIV acquisition, people who inject drugs should be included and

p.000002: Researchers and trial sponsors should recruit women into clinical trials in order to verify safety and efficacy from
p.000002: their standpoint, including immunogenicity in the case of vaccine trials, since women throughout the life span,

p.000030: By definition, HIV prevention research must follow the epidemic. In order to test if a biomedical HIV prevention
p.000030: intervention works, large numbers of individuals at high risk for HIV infection must be recruited for clinical trials.
p.000030: Sites based in communities with mature HIV epidemics have lower incidence rates and may be most appropriate for safety
p.000030: studies. Sites in communities with younger epidemics may be better suited for efficacy trials. However, partici- pating
p.000030: communities and populations, particularly for large-scale efficacy trials, will generally be characterized by
p.000030: multiple vulnera- bilities. The same factors that put these individuals at higher risk for exposure to HIV also make
p.000030: them vulnerable to cultural exclusion, social inequality, economic exploitation, and political oppression. Examples of
p.000030: populations that may have an increased vulnerability include women, children and adolescents, men who have sex with
p.000030: men, injecting drug users, sex workers, transgender persons, indig- enous populations, the poor, the homeless, and
p.000030: communities from resource-poor settings in high-income and low- and middle-income countries. At the same time, it is
p.000030: precisely these populations who stand to benefit most from the successful development of a new biomedical HIV

p.000034: Although the enrolment of pregnant or breastfeeding women complicates the analysis of risks and benefits,
p.000034: because both the woman and the foetus or infant could be benefited or harmed, such women should be viewed as
p.000034: autonomous decision-makers, capable of making an informed choice for themselves and for their foetus or child. In order

p.000035:
p.000035: Children3 , including infants and adolescents, should be eligible for enrolment in biomedical HIV preventive
p.000035: intervention trials, both as a matter of equity and because in many communities throughout the world children are at a
p.000035: higher risk of HIV exposure. Infants born to HIV-infected mothers are at risk of becoming infected during birth and
p.000035: during the postpartum period through breastfeeding. Many adolescents are also at higher risk of HIV infection due to
p.000035: sexual activity, lack of access to HIV prevention education and means, and through injecting drugs with non-sterile

p.000036:
p.000036: It is generally understood that adolescents, prior to initiation of sexual activity and exposure to any risk of HIV
p.000036: infection, will be the primary target for any public health intervention involving a successful biomedical
p.000036: intervention. In the case of HIV vaccine candidates and other products requiring licensure that would have an
p.000036: indication for use in both adolescents and adults, it is impera- tive that there be no delays in achieving simultaneous
p.000036: licensure/ registration for both populations. It is therefore recommended in such cases, that adolescents be included
p.000036: in trials as soon as possible when a candidate has sufficient promise to advance into a Phase IIB or Phase III efficacy
p.000036: trial in adults (see Guidance Point 5). The use of bridging studies designed for safety (and, in the case of an HIV
p.000036: vaccine, immunogenicity testing), but not including HIV infection as a primary endpoint could be considered as an
p.000036: alterna- tive for younger adolescents, to be carried out in parallel to Phase III trials in adults.
p.000036:
p.000036: There may be legal barriers to enrolment of younger adolescents into a clinical trial in which sexual activity is
p.000036: directly linked to achieving primary endpoints. It is imperative that trials are conducted in compliance with the
p.000036: protective laws and regulations applicable at the trial sites, including those related to legal age of consent, the age
p.000036: of majority, the legal age for consensual sex, legal obligations to report abuse or neglect, and other aspects which
p.000036: may have an impact on the conduct of biomedical HIV preventive intervention trials. Thus, undertaking a survey of
p.000036: applicable local laws is an essential requirement to ensure required compliance prior to making plans for such trials
p.000036: in a particular country.

p.000038: During the informed consent process, it is recommended that investigators conduct the consent (parent) and
p.000038: assent (adolescent) processes separately. This would ensure confidential counselling for the adolescent and protect the
p.000038: adolescent’s privacy (see Guidance Point 18). It is also important to inform adolescents of all the elements
p.000038: disclosed to an adult, and to determine that the adoles- cent understands what s/he is assenting to (see Guidance Point
p.000038: 16). The consent process and document should describe clearly what information regarding the adolescent will or will
p.000038: not be disclosed to the parent(s) or legal guardian, as well as what medical or other services will be provided to
p.000038: the adolescent, as needed, without further parental permission.
p.000038:
p.000038: In some settings, children may have guardians who have not been legally recognized by a court as such. Adolescents who
p.000038: do not have parents or legally recognized guardians should not be automatically excluded from participation in a
p.000038: biomedical HIV preventive inter- vention trial. Participation could be considered for such adolescents who wish to
p.000038: participate in a trial, as long as a protective ethical oversight mechanism can be established in compliance with the
p.000038: local law. In addition, mechanisms should be established for an independent evaluation of the capacity of such
p.000038: adolescents to give informed consent.

p.000057: and participants what measures they will be taking to protect privacy and personal informa- tion, and what limitations
p.000057: may exist on their ability to do so.
p.000057: All participants are entitled to confidentiality of information disclosed or discovered in the recruitment and informed
p.000057: consent processes, and during conduct of the trial. Community involvement should not compromise the confidentiality
p.000057: of study participants. This is of partic- ular importance with respect to participants from vulnerable popu- lations,
p.000057: women and adolescents, who may be socially susceptible to stigma and discrimination (see Guidance Points 8, 9, 10).
p.000057: There may be specific exceptions to the duty of confidentiality for legal or ethical reasons, but those exceptions
p.000057: should be prospectively identified and disclosed to the participant during the informed consent process.
p.000057: Legal exceptions to the duty to maintain confidentiality might exist, for example, where disclosure is mandated by a
p.000057: court order or where there is a duty to report to public health authorities. In the case of children and adolescents,
p.000057: reporting of abuse and neglect might be required under child protection laws. Similarly, the reporting of domestic
p.000057: violence might be a legal duty.Trial staff should be trained to identify instances where there is such a mandatory
p.000057: reporting duty.
p.000057: Breach of confidentiality might also be warranted on ethical grounds, so as to notify sexual partners. For example,
p.000057: where women participate in microbicide trials, there may be unknown risks of harm to male partners. The sponsor and
p.000057: researcher should have a mechanism for them to come forward to report possible negative consequences and make sure that
p.000057: they are notified of such, preferably by the female participants. Likewise, when participants become HIV positive,
p.000057: sexual partners at ongoing risk should be notified for referral to testing programmes and treatment facilities.
p.000057: However, researchers and research staff should be sensitive to the possibility of domestic violence as a result of
p.000057: partner notification.

p.000031: Decision-making around conducting a biomedical HIV prevention trial needs to consider in what ways the trial might

p.000009: In some biomedical HIV prevention trials, individuals other than the trial participants may experience risks if they
p.000009: are exposed to the experimental product and may experience benefits if the product is effective. For example in trials
p.000009: of prophylaxis of mother-to-child transmission, the foetus is exposed to the prophylactic antiretroviral regimen in
p.000009: addition to the mother. If the mother develops antiretroviral resistance, she may transmit resistant virus to the
p.000009: infant. When the intervention is effective, the newborn baby is protected. In trials of vaginal microbicides, male
p.000009: sexual partners may be exposed to the product even when condoms are used. In trials of successful vaccine candidates,
p.000009: not only sexual partners benefit but communities may benefit from population level effects.

p.000032: Researchers and trial sponsors should include women in clinical trials in order to verify safety and
p.000032: efficacy from their standpoint, including immunogenicity in the case of vaccine trials, since women throughout the
p.000032: life span, including those who are sexually active and may become pregnant, be pregnant or be breastfeeding,
p.000032: should be recipients of future safe and effective biomedical HIV prevention interventions. During such research,
p.000032: women’s autonomy should be respected and they should receive adequate information to make informed choices
p.000032: about risks to themselves, as well as to their foetus or breastfed infant, where applicable.

p.000032:
p.000032: Women throughout the life span, including those who are sexually active and may become pregnant, be pregnant or be
p.000032: breastfeeding, should be recipients of future safe and effective biomedical HIV prevention products and therefore
p.000032: should be eligible for enrolment in biomedical HIV prevention trials, both as a matter of equity and because in many
p.000032: communities throughout the world women, particularly young women, are at higher risk of HIV exposure.
p.000032: Therefore, the efficacy of candidate biomedical HIV prevention products, and their immunogenicity in the case of
p.000032: vaccines, should be established for women. Clinical trials should also be designed with the intent of establishing the
p.000032: safety of candidate biomedical prevention products for the health of the woman and, where appli- cable, her foetus,
p.000032: breastfed infant and, in the case of vaginal or rectal microbicides, her sexual partners.
p.000032:
p.000032: If the safety of the biomedical HIV prevention product for a pregnant women and her foetus has not been established

p.000033: women should be conducted early on in the research, at the stage when a candidate has sufficient promise to advance
p.000033: into a Phase IIB or Phase III efficacy trial in adults or only after the trial product has been shown to be effective
p.000033: should be discussed and resolved on a case-by-case basis early on in the planning of the research design. In any event,
p.000033: researchers should monitor adverse events among pregnant women and women who become pregnant in the course of the
p.000033: trial, notably in the case of a miscarriage, to determine their relatedness to the biomedical HIV preventive
p.000033: intervention.
p.000033:
p.000033: The most notable data gap in the evaluation of some prevention methods, particularly in phase I and II trials, is
p.000033: adequate evaluation of safety and efficacy among women. Barriers for women partici- pating in trials include
p.000033: contraceptive requirements, issues related to current or future fertility, concerns about safety for the foetus, and
p.000033: fear of being labelled as being at higher risk for HIV exposure. Also, women present issues of particular complexity
p.000033: with regard to recruitment and informed consent. In some cultures, women and girl adolescents may not be able to
p.000033: exercise true autonomy in light of the influence of their parents or sexual partners (see Guidance Point 7). In others,
p.000033: young people may be more informed than their parents, and their view and their parents’ or partners’ views on
p.000033: their participation may differ. Further, the need for HIV testing or pregnancy testing to assess eligibility for
p.000033: inclusion in a trial may raise difficult issues regarding the maintenance of appropriate confi- dentiality.
p.000033: Researchers and research staff should improve recruit- ment strategies by anticipating and finding solutions to
p.000033: address and overcome these barriers (see Guidance Point 7). Appropriate reproductive and sexual health counselling
p.000033: and ancillary services, including family planning, should be provided to trial participants.

p.000034: Although the enrolment of pregnant or breastfeeding women complicates the analysis of risks and benefits,
p.000034: because both the woman and the foetus or infant could be benefited or harmed, such women should be viewed as
p.000034: autonomous decision-makers, capable of making an informed choice for themselves and for their foetus or child. In order
p.000034: for pregnant women to be able to make an informed choice for their foetus/breastfed infant,they should be duly informed
p.000034: about any potential for teratogenesis and other known or unknown risks to the foetus and/or the breastfed infant. If
p.000034: there are risks related to breastfeeding, women should be informed of the availability of nutritional substitutes and
p.000034: other supportive services. Researchers should observe and study the positive and adverse effects on the children of
p.000034: these women.They should maintain pregnancy registries to collect data on outcomes of pregnancies that inadvertently
p.000034: occur during the trial, follow-up babies born to women participants, and take due measures for protection of privacy
p.000034: and personal data. In the particular case of trials of prevention of mother-to-child transmis- sion, both women and

p.000003: Guidance Point 14: Care and Treatment
p.000003: Participants who acquire HIV infection during the conduct of a biomedical HIV prevention trial should be provided
p.000003: access to treatment regimens from among those internationally recognised as optimal. Prior to initiation of a trial,
p.000003: all research stakeholders should come to agreement through participatory processes on mechanisms to provide and sustain
p.000003: such HIV-related care and treatment.
p.000003: Guidance Point 15: Control Groups

p.000017: prevention product development programme from phase I through phase III and beyond (see Guidance Point 6), to the
p.000017: distribution of a safe and effective HIV prevention tool. All participating parties should define the nature of this
p.000017: ongoing relationship. It should include appropriate representation from the community on committees charged with the
p.000017: review, approval, and monitoring of a biomedical HIV prevention trial. As with investigators and sponsors, communities

p.000017: organizations, national institutions and governments, as well as researchers and community representatives from the
p.000017: trial site. Partnership agreements should include a clear delineation of roles for all stakeholders and should specify
p.000017: the responsibilities of sponsors, governments, community, advocacy organiza- tions, and media, as well as researchers

p.000018: requirements such as trans- portation to the meeting site. Educational materials should be designed in an accessible
p.000018: format, using easy to understand language. Adequate consultation and full participation in the planning process will
p.000018: require more than formal community meetings, as such meetings may alienate some people or be inaccessible to others due
p.000018: to the timing or the format. The principal investigator and site research staff should make efforts to reach out to

p.000057: and participants what measures they will be taking to protect privacy and personal informa- tion, and what limitations
p.000057: may exist on their ability to do so.
p.000057: All participants are entitled to confidentiality of information disclosed or discovered in the recruitment and informed
p.000057: consent processes, and during conduct of the trial. Community involvement should not compromise the confidentiality
p.000057: of study participants. This is of partic- ular importance with respect to participants from vulnerable popu- lations,
p.000057: women and adolescents, who may be socially susceptible to stigma and discrimination (see Guidance Points 8, 9, 10).
p.000057: There may be specific exceptions to the duty of confidentiality for legal or ethical reasons, but those exceptions
p.000057: should be prospectively identified and disclosed to the participant during the informed consent process.
p.000057: Legal exceptions to the duty to maintain confidentiality might exist, for example, where disclosure is mandated by a
p.000057: court order or where there is a duty to report to public health authorities. In the case of children and adolescents,
p.000057: reporting of abuse and neglect might be required under child protection laws. Similarly, the reporting of domestic
p.000057: violence might be a legal duty.Trial staff should be trained to identify instances where there is such a mandatory
p.000057: reporting duty.
p.000057: Breach of confidentiality might also be warranted on ethical grounds, so as to notify sexual partners. For example,
p.000057: where women participate in microbicide trials, there may be unknown risks of harm to male partners. The sponsor and
p.000057: researcher should have a mechanism for them to come forward to report possible negative consequences and make sure that
p.000057: they are notified of such, preferably by the female participants. Likewise, when participants become HIV positive,
p.000057: sexual partners at ongoing risk should be notified for referral to testing programmes and treatment facilities.

p.000058: protect confidentiality, workers in the clinic or programme setting where recruitment is taking place should first ask
p.000058: potential volunteers whether they would be willing to speak to a researcher who will provide information about trial
p.000058: participation. In the case of adolescents being recruited for endpoint efficacy trials, researchers should inquire
p.000058: whether their parents are aware of their sexual behaviour and explain that parental permission will be required for
p.000058: enrolment. In the case of media interest in the trial, research staff members should also advise participants of
p.000058: possible negative impact that may result from public exposure. Community advisory boards may need training to enable
p.000058: members to interview about the trial in ways that do not compromise the duty of confidentiality owed to individual
p.000058: participants or jeopardise their right to privacy.
p.000058: Research may involve collecting and storing private and sensitive data relating to individuals and communities
p.000058: including data derived from biological samples (see Guidance Point 16). Measures of data protection are of major
p.000058: importance in large-scale studies such as HIV prevention trials which establish large databases to integrate clinical
p.000058: data and monitor public health effect. Decisions regarding which personal data are to be collected and stored must be
p.000058: based on the requirements of the trial design and the medical needs of participants. Personal identifiable data should
p.000058: be collected only by people who have signed a confidentiality agreement. The collection of personal identifiable data
p.000058: should be kept at a minimum and such data should not be stored longer than necessary. Procedures should be in place to
p.000058: monitor the use of the system where the data are stored in order to detect potential or actual security threats.

p.000057: All participants are entitled to confidentiality of information disclosed or discovered in the recruitment and informed

p.000057: Legal exceptions to the duty to maintain confidentiality might exist, for example, where disclosure is mandated by a

p.000010:
p.000010: situation demands particular attention to ways to address the differing perspectives, interests and capacities of trial
p.000010: sponsors, countries, and communities engaged in trials with the goal of encouraging the urgent development of
p.000010: additional safe and effective biomedical HIV prevention tools, in ethically accept- able manners, and their early
p.000010: distribution to populations most in need. Countries and communities considering participa- tion in biomedical HIV
p.000010: prevention trials should be encour- aged and given the capacity to make decisions for themselves regarding their
p.000010: participation, based on their own health and human development priorities, in a context of equal collabora- tion with
p.000010: sponsors.
p.000010: HIV infection is both highly feared and stigmatised. This is in large part because it is associated with blood, death,
p.000010: sex, and activities which may not be legally sanctioned, such as commer- cial sex, men having sex with men, and illicit
p.000010: substance use. These are issues which are often difficult to address openly
p.000010: - at a societal and individual level. As a result, people living with HIV and those affected by AIDS may experience
p.000010: stigma, discrimination, and even violence; some communities continue to deny the existence and prevalence of HIV
p.000010: infection. Furthermore, vulnerability to HIV exposure and to the impact of AIDS is greater where people are
p.000010: marginalized due to their social, economic, and legal status. These factors increase the risk of social and
p.000010: psychological harm for people participating in biomedical HIV prevention trials. Additional efforts must be made to
p.000010: address these increased risks and to ensure that the risks participants take are justified by the anticipated benefits
p.000010: of the preventive intervention to the participants themselves or to others in the future.
p.000010: A key means by which to protect participants and the commu- nities from which they come is to ensure that the community
p.000010: in which the research is carried out is meaningfully involved in the design, implementation, monitoring, and
p.000010: dissemination of results of HIV prevention trials, including the involvement of representatives from marginalized

p.000057: may exist on their ability to do so.
p.000057: All participants are entitled to confidentiality of information disclosed or discovered in the recruitment and informed
p.000057: consent processes, and during conduct of the trial. Community involvement should not compromise the confidentiality
p.000057: of study participants. This is of partic- ular importance with respect to participants from vulnerable popu- lations,
p.000057: women and adolescents, who may be socially susceptible to stigma and discrimination (see Guidance Points 8, 9, 10).
p.000057: There may be specific exceptions to the duty of confidentiality for legal or ethical reasons, but those exceptions
p.000057: should be prospectively identified and disclosed to the participant during the informed consent process.
p.000057: Legal exceptions to the duty to maintain confidentiality might exist, for example, where disclosure is mandated by a
p.000057: court order or where there is a duty to report to public health authorities. In the case of children and adolescents,
p.000057: reporting of abuse and neglect might be required under child protection laws. Similarly, the reporting of domestic
p.000057: violence might be a legal duty.Trial staff should be trained to identify instances where there is such a mandatory
p.000057: reporting duty.
p.000057: Breach of confidentiality might also be warranted on ethical grounds, so as to notify sexual partners. For example,
p.000057: where women participate in microbicide trials, there may be unknown risks of harm to male partners. The sponsor and
p.000057: researcher should have a mechanism for them to come forward to report possible negative consequences and make sure that
p.000057: they are notified of such, preferably by the female participants. Likewise, when participants become HIV positive,
p.000057: sexual partners at ongoing risk should be notified for referral to testing programmes and treatment facilities.
p.000057: However, researchers and research staff should be sensitive to the possibility of domestic violence as a result of
p.000057: partner notification.

p.000058: potential volunteers whether they would be willing to speak to a researcher who will provide information about trial

p.000036: intervention. In the case of HIV vaccine candidates and other products requiring licensure that would have an
p.000036: indication for use in both adolescents and adults, it is impera- tive that there be no delays in achieving simultaneous
p.000036: licensure/ registration for both populations. It is therefore recommended in such cases, that adolescents be included
p.000036: in trials as soon as possible when a candidate has sufficient promise to advance into a Phase IIB or Phase III efficacy
p.000036: trial in adults (see Guidance Point 5). The use of bridging studies designed for safety (and, in the case of an HIV
p.000036: vaccine, immunogenicity testing), but not including HIV infection as a primary endpoint could be considered as an
p.000036: alterna- tive for younger adolescents, to be carried out in parallel to Phase III trials in adults.
p.000036:
p.000036: There may be legal barriers to enrolment of younger adolescents into a clinical trial in which sexual activity is
p.000036: directly linked to achieving primary endpoints. It is imperative that trials are conducted in compliance with the
p.000036: protective laws and regulations applicable at the trial sites, including those related to legal age of consent, the age
p.000036: of majority, the legal age for consensual sex, legal obligations to report abuse or neglect, and other aspects which
p.000036: may have an impact on the conduct of biomedical HIV preventive intervention trials. Thus, undertaking a survey of
p.000036: applicable local laws is an essential requirement to ensure required compliance prior to making plans for such trials
p.000036: in a particular country.

p.000002: Researchers and trial sponsors should recruit women into clinical trials in order to verify safety and efficacy from
p.000002: their standpoint, including immunogenicity in the case of vaccine trials, since women throughout the life span,
p.000002: including those who may become pregnant, be pregnant or be breastfeeding, should be recipients of future safe and

p.000002: standpoint, in addition to immunogenicity in the case of vaccines, since they should be recipients of future biomedical
p.000002: HIV preventive interventions. Researchers, trial sponsors, and countries should make efforts to design and implement
p.000002: biomedical HIV prevention product development programmes that address the particular safety, ethical, and legal

p.000028: Selection and recruitment of communities and individuals for partici- pation in a trial must be fair and should create
p.000028: a research climate which shows respect for all persons.This encompasses decisions about who will be included
p.000028: through the formulation of inclusion and exclusion criteria, and through the strategy adopted for recruiting
p.000028: participants. The scientific goals of the study should be the primary basis for determining the individuals who
p.000028: will be recruited and enrolled. Individuals should not be excluded from the opportunity to participate without a
p.000028: good scientific reason or a susceptibility to risk that justifies their exclusion. Social and cultural factors should
p.000028: be considered to determine the vulnerability within the community of individuals who are either included or excluded.
p.000028: In particular, gender- sensitive approaches are key when designing recruitment procedures and special attention needs

p.000029: In some situations, voluntariness of participation may be compromised by factors such as social
p.000029: marginalization, political powerlessness, and economic dependence. Voluntariness of participation may also be
p.000029: compromised where there is a cultural tradition of men holding decision making authority in marital
p.000029: relationships, parental control of women, and other forms of social subjugation and coercion (see Guidance
p.000029: Point 9). In some communities, it is customary to require the authorization of a third party, such as a community
p.000029: elder or head of a family, in order for investigators to enter the community or to approach individuals. However, the
p.000029: third party only gives permission to invite individuals to participate and such authorisation or influence must not be
p.000029: used as a substitute for individual informed consent.Trials should not be conducted where truly voluntary participation

p.000030: By definition, HIV prevention research must follow the epidemic. In order to test if a biomedical HIV prevention
p.000030: intervention works, large numbers of individuals at high risk for HIV infection must be recruited for clinical trials.
p.000030: Sites based in communities with mature HIV epidemics have lower incidence rates and may be most appropriate for safety
p.000030: studies. Sites in communities with younger epidemics may be better suited for efficacy trials. However, partici- pating
p.000030: communities and populations, particularly for large-scale efficacy trials, will generally be characterized by
p.000030: multiple vulnera- bilities. The same factors that put these individuals at higher risk for exposure to HIV also make
p.000030: them vulnerable to cultural exclusion, social inequality, economic exploitation, and political oppression. Examples of
p.000030: populations that may have an increased vulnerability include women, children and adolescents, men who have sex with
p.000030: men, injecting drug users, sex workers, transgender persons, indig- enous populations, the poor, the homeless, and
p.000030: communities from resource-poor settings in high-income and low- and middle-income countries. At the same time, it is
p.000030: precisely these populations who stand to benefit most from the successful development of a new biomedical HIV
p.000030: prevention product or method. For these reasons, it is imperative to ensure protection of the rights of participants
p.000030: in biomedical HIV prevention trials, and respect for their dignity, safety, and welfare.

p.000031: Decision-making around conducting a biomedical HIV prevention trial needs to consider in what ways the trial might

p.000031: or exploitation may be so severe that the risk outweighs the benefit of conducting the study in that population. In
p.000031: such populations, biomed- ical HIV prevention trials should not be conducted.
p.000031: Sensitivity to factors of potential vulnerability, including language and cultural barriers, should inform procedures
p.000031: for recruiting and screening potential participants, informed consent processes, and the support, care, and treatment
p.000031: that participants receive in relation to the trial. If a scien- tifically appropriate population is identified as

p.000032:
p.000032: Researchers and trial sponsors should include women in clinical trials in order to verify safety and
p.000032: efficacy from their standpoint, including immunogenicity in the case of vaccine trials, since women throughout the
p.000032: life span, including those who are sexually active and may become pregnant, be pregnant or be breastfeeding,
p.000032: should be recipients of future safe and effective biomedical HIV prevention interventions. During such research,
p.000032: women’s autonomy should be respected and they should receive adequate information to make informed choices
p.000032: about risks to themselves, as well as to their foetus or breastfed infant, where applicable.
p.000032:
p.000032:
p.000032: Women throughout the life span, including those who are sexually active and may become pregnant, be pregnant or be
p.000032: breastfeeding, should be recipients of future safe and effective biomedical HIV prevention products and therefore
p.000032: should be eligible for enrolment in biomedical HIV prevention trials, both as a matter of equity and because in many
p.000032: communities throughout the world women, particularly young women, are at higher risk of HIV exposure.
p.000032: Therefore, the efficacy of candidate biomedical HIV prevention products, and their immunogenicity in the case of
p.000032: vaccines, should be established for women. Clinical trials should also be designed with the intent of establishing the
p.000032: safety of candidate biomedical prevention products for the health of the woman and, where appli- cable, her foetus,
p.000032: breastfed infant and, in the case of vaginal or rectal microbicides, her sexual partners.
p.000032:
p.000032: If the safety of the biomedical HIV prevention product for a pregnant women and her foetus has not been established
p.000032: prior to commence- ment of the trial, women who become pregnant in the course of the trial might be discontinued from
p.000032: using the product, which would

p.000033: result in loss to follow-up of the participating women.Therefore the question of whether a safety study for pregnant
p.000033: women should be conducted early on in the research, at the stage when a candidate has sufficient promise to advance
p.000033: into a Phase IIB or Phase III efficacy trial in adults or only after the trial product has been shown to be effective
p.000033: should be discussed and resolved on a case-by-case basis early on in the planning of the research design. In any event,
p.000033: researchers should monitor adverse events among pregnant women and women who become pregnant in the course of the
p.000033: trial, notably in the case of a miscarriage, to determine their relatedness to the biomedical HIV preventive
p.000033: intervention.
p.000033:
p.000033: The most notable data gap in the evaluation of some prevention methods, particularly in phase I and II trials, is
p.000033: adequate evaluation of safety and efficacy among women. Barriers for women partici- pating in trials include
p.000033: contraceptive requirements, issues related to current or future fertility, concerns about safety for the foetus, and
p.000033: fear of being labelled as being at higher risk for HIV exposure. Also, women present issues of particular complexity
p.000033: with regard to recruitment and informed consent. In some cultures, women and girl adolescents may not be able to
p.000033: exercise true autonomy in light of the influence of their parents or sexual partners (see Guidance Point 7). In others,
p.000033: young people may be more informed than their parents, and their view and their parents’ or partners’ views on
p.000033: their participation may differ. Further, the need for HIV testing or pregnancy testing to assess eligibility for
p.000033: inclusion in a trial may raise difficult issues regarding the maintenance of appropriate confi- dentiality.
p.000033: Researchers and research staff should improve recruit- ment strategies by anticipating and finding solutions to
p.000033: address and overcome these barriers (see Guidance Point 7). Appropriate reproductive and sexual health counselling
p.000033: and ancillary services, including family planning, should be provided to trial participants.

p.000034: Although the enrolment of pregnant or breastfeeding women complicates the analysis of risks and benefits,
p.000034: because both the woman and the foetus or infant could be benefited or harmed, such women should be viewed as
p.000034: autonomous decision-makers, capable of making an informed choice for themselves and for their foetus or child. In order
p.000034: for pregnant women to be able to make an informed choice for their foetus/breastfed infant,they should be duly informed
p.000034: about any potential for teratogenesis and other known or unknown risks to the foetus and/or the breastfed infant. If
p.000034: there are risks related to breastfeeding, women should be informed of the availability of nutritional substitutes and
p.000034: other supportive services. Researchers should observe and study the positive and adverse effects on the children of
p.000034: these women.They should maintain pregnancy registries to collect data on outcomes of pregnancies that inadvertently

p.000034: and personal data. In the particular case of trials of prevention of mother-to-child transmis- sion, both women and

p.000050: The biological conditions that prevailed during the initial trial demonstrating efficacy of a biomedical HIV prevention

p.000057: There may be specific exceptions to the duty of confidentiality for legal or ethical reasons, but those exceptions
p.000057: should be prospectively identified and disclosed to the participant during the informed consent process.
p.000057: Legal exceptions to the duty to maintain confidentiality might exist, for example, where disclosure is mandated by a
p.000057: court order or where there is a duty to report to public health authorities. In the case of children and adolescents,
p.000057: reporting of abuse and neglect might be required under child protection laws. Similarly, the reporting of domestic
p.000057: violence might be a legal duty.Trial staff should be trained to identify instances where there is such a mandatory
p.000057: reporting duty.
p.000057: Breach of confidentiality might also be warranted on ethical grounds, so as to notify sexual partners. For example,
p.000057: where women participate in microbicide trials, there may be unknown risks of harm to male partners. The sponsor and
p.000057: researcher should have a mechanism for them to come forward to report possible negative consequences and make sure that
p.000057: they are notified of such, preferably by the female participants. Likewise, when participants become HIV positive,
p.000057: sexual partners at ongoing risk should be notified for referral to testing programmes and treatment facilities.
p.000057: However, researchers and research staff should be sensitive to the possibility of domestic violence as a result of
p.000057: partner notification.

p.000065: layer of vulnerability for people who inject drugs who are women, men who have sex with men, or people who are
p.000065: transgender or intersex. They may experi- ence increased vulnerability to unprotected sex and unsafe injections,

p.000031:
p.000031: Decision-making around conducting a biomedical HIV prevention trial needs to consider in what ways the trial might
p.000031: increase or decrease vulnerabilities. On the one hand, a trial might increase a participant’s risk of exposure to
p.000031: stigmatisation and discrimination if it highlights a population’s increased vulnerability to HIV exposure. On the
p.000031: other hand, a trial might decrease vulnerability, if it empowers the community or provides tangible assistance to
p.000031: participants, for example by improving the accessibility, affordability, and quality of appropriate healthcare
p.000031: services in the community. A social and political analysis should be carried out early on in planning the research
p.000031: process, to assess determi- nants of vulnerability, such as poverty, gender, age, ethnicity, sexuality, health,
p.000031: employment, education, and legal conditions in potential partic- ipating communities. Findings from this analysis
p.000031: should inform the design of research protocols, which should be sensitive to emerging information on incidental risks
p.000031: of social harm throughout the course of a trial. Research protocols might also include ongoing independent monitoring
p.000031: of a trial in relation to its impact on the vulnerabilities of communities participating in the study (see Guidance
p.000031: Point 17).
p.000031: The particular aspects of a social context that create conditions for exploi- tation or increased vulnerability should
p.000031: be described in the research protocol, as should the safeguards and measures that will be taken to prevent and overcome
p.000031: them. In some potential research populations (countries or communities), conditions affecting potential vulnerability

p.000055: the process by which it is conducted and not solely on the structure and content of the informed consent document. The
p.000055: informed consent process should be designed and monitored to empower participants to allow them to make appropriate
p.000055: decisions about continuing or withdrawing from the study. Special attention should be given to ensure that individuals
p.000055: are aware of their right to withdraw from a trial without any penalty, and that they are actually free to do so.
p.000055: Similarly, there are many ways in which risk-reduction interventions (coun- selling and access to means of HIV

p.000065: People who inject drugs suffer several layers of vulnerability (see Guidance Point 8). Criminalization of their drug

p.000065: care professionals and policy-makers; personal mental health issues, preceding or resulting from their drug use;
p.000065: poverty; racism, if they are members of certain racially-defined groups; and marginalization. Gender adds an additional
p.000065: layer of vulnerability for people who inject drugs who are women, men who have sex with men, or people who are
p.000065: transgender or intersex. They may experi- ence increased vulnerability to unprotected sex and unsafe injections,
p.000065: exploitation, discrimination, lack of sensitivity to their specific needs, and under-resourcing of services to meet
p.000065: their needs.
p.000065:
p.000065: Prior to commencing a trial, researchers and sponsors should conduct formative research to gain understanding of
p.000065: particular contextual challenges and vulnerabilities that people who inject drugs face and to begin building
p.000065: trust with people who inject drugs and their networks. The research protocol should describe the vulnerabilities
p.000065: identified, as well as steps that have been or will be taken to create a safe enabling environment for trial
p.000065: participants. HIV prevention trials should not be conducted where there are insurmountable barriers to ensure safety,
p.000065: protection, and confidentiality of trial participants (see Guidance Point 18). For this reason, and because adherence
p.000065: to the principle of autonomy cannot be guaranteed, HIV prevention trials should not be conducted in compulsory drug

p.000066: right to confidentiality and privacy is not breached (see Guidance Point 18). Recruitment within voluntary drug
p.000066: treatment centres, especially by service providers upon whom people who inject drugs are dependent for on-going
p.000066: care, may pose special problems regarding voluntariness of trial participation. Generally, potential trial
p.000066: participants should not be recruited by their service providers. Where respondent-driven recruitment and other
p.000066: snowball-type recruitment techniques are used, confidenti- ality should be emphasized to recruiters. Research teams
p.000066: should be trained to identify when a potential participant is unable to make a voluntary, informed decision about trial

p.000066: and voluntariness, access to risk reduction measures while incarcerated, access to a physician, and post-release

p.000050:
p.000050: Participants in both the control arm and the intervention arm should receive all established effective HIV risk
p.000050: reduction measures. The use of a placebo control arm is ethically acceptable in a biomedical HIV prevention trial
p.000050: only when there is no HIV prevention modality of the type being studied that has been scientifically validated in
p.000050: comparable populations or approved by relevant authorities.
p.000050:
p.000050: Aside from male circumcision, a biomedical HIV prevention inter- vention with proven efficacy in preventing HIV
p.000050: acquisition or HIV- related disease does not currently exist. Therefore, until an effica- cious intervention is
p.000050: developed, the use of a placebo control arm could be ethically acceptable in appropriately designed protocols,
p.000050: such as three-arm trials. For example, there may be compelling scien- tific reasons which justify the use of a placebo
p.000050: rather than a known effective biomedical HIV intervention in the following instances:
p.000050: An effective HIV vaccine exists but it is not known to be effective against the virus that is prevalent in the research
p.000050: population.
p.000050: The biological conditions that prevailed during the initial trial demonstrating efficacy of a biomedical HIV prevention
p.000050: product are so different from the conditions in the proposed research population that the results of the initial trial
p.000050: are not generalizable and cannot be directly applied to the research population under consideration.
p.000050: A microbicide shown to be effective for vaginal intercourse may not be effective for rectal intercourse.
p.000050: Effectiveness of an intervention in one population may not be reproduced in the context of another population if the
p.000050: success of the intervention is strongly related to behaviour or behavioural modification and conditions of product
p.000050: utilisation. For example, a partially effective, coitally dependent microbicide evaluated among women in stable
p.000050: partnerships may not be generalizable to women with multiple casual partners.

p.000052: consent is given. Informed consent is a process, not just a piece of paper to be read and signed. The information
p.000052: should be presented in appropriate forms and languages, including written information sheets. In addition, there
p.000052: should be oral communication of information, especially for participants who may be illiterate, and standardized tests
p.000052: for assessment of comprehension, where necessary.
p.000052:
p.000052: In addition to the standard content of informed consent prior to participation in a biomedical HIV preventive
p.000052: intervention trial, each prospective participant must be informed, using appropriate language and technique, of the
p.000052: following specific details:
p.000052:
p.000052: the reasons they have been chosen as prospective participants, including whether they are at higher risk of HIV
p.000052: exposure;
p.000052: that the biomedical HIV prevention product is experimental and it is not known that it will prevent HIV infection or
p.000052: disease, and

p.000053: prevention product through random assignment;
p.000053: that they will receive counselling concerning how to reduce their risk of HIV exposure and access to risk-reduction
p.000053: means (in particular, male and female condoms, clean injecting equipment, and where relevant, male
p.000053: circumcision); and that, in spite of these risk-reduction efforts, some of the partici- pants may become
p.000053: infected, particularly in the case of phase III trials where large numbers of participants at higher risk of HIV
p.000053: exposure are participating;
p.000053: the specific risks for physical harm, as well as for psychological and social harm (see Guidance Point 11), the types
p.000053: of treatment and compensation that are available for harm, and the services to which they may be referred should harm
p.000053: occur;
p.000053: the nature and duration of care and treatment that is available, and how it can be accessed, if they become infected
