Good Participatory Practice (GPP) Guidelines
Ethical and effective stakeholder engagement throughout clinical trials and research agendas for HIV prevention and beyond

The Good Participatory Guidelines (GPP) provide trial funders, sponsors and implementers with systematic guidance on how to effectively engage with all stakeholders in the design and conduct of clinical trials for biomedical HIV prevention.
GPP is a linchpin to the ethical conduct of clinical trials, global health equity and pandemic preparedness.
Overview
In 2004, Cambodia’s Prime Minister halted planned PrEP efficacy trials set to take place in Cambodia and Cameroon. Local, national, and international stakeholders had raised concerns, highlighting a disconnect with research teams and divergent perspectives on the ethics of the trials’ design. Although the proposed trials had been designed in accordance with international guidance on ethics and clinical research, there was no common document or guideline for conducting or evaluating stakeholder engagement. The ensuing controversies crystallized the need for a reference guide, inclusively created with all relevant stakeholders, on ethical and effective stakeholder engagement related to clinical trials for HIV prevention.
About This Project
In response, AVAC and UNAIDS convened a multidisciplinary international group including community advocates, research staff, and NGO representatives, who drafted the initial edition of GPP. This work drew from foundational documents covering ethical guidance and core principles on research ethics.
The draft guidelines were further refined through broad consultation involving a wide range of stakeholders. In 2007 the Joint United Nations Programme on HIV/AIDS (UNAIDS) and AVAC published the first edition of the Good Participatory Practice Guidelines for biomedical HIV prevention trials.
These guidelines have been adapted for tuberculosis (TB), COVID-19, and emerging pathogens, and they should be further adapted to other areas of clinical research aimed at global disease threats.
What is GPP?
The GPP guidelines were created to provide a consistent global standard for stakeholder engagement throughout the life-cycle of the research enterprise, from trial design to trial conduct to the dissemination of research results to, finally, access to proven intervention.
GPP Guidelines are written for research entities including trial sites, funders, and sponsors of research. External stakeholders, such as advocates, policy makers, and communities are encouraged to use the guidelines to hold research entities accountable, or implement components of the guidelines directly. This ‘external’ approach to GPP is a powerful way to hold research entities responsible for community-centered trials.
As a point of reference for how to engage stakeholders, GPP has given rise to a robust community of practice. It has created a process for deeper trust between research teams and other stakeholders and greater understanding about how trials will affect communities. This in turn improves trial design and conduct, and improves how trial results are understood, accepted and applied, regardless of the outcome.
GPP is a way to achieve the most community-centric results from a trial or research agenda – however, it is not a guarantee of successful trial results. GPP gives researchers a better sense of how communities will perceive trials and products and provides an opportunity to adapt and improve those perceptions. But GPP alone cannot induce participants to stay in a trial, adhere to a trial regimen, guarantee a product will be accepted, or eliminate the risk of controversy. GPP does provide a framework for navigating questions and controversy if they occurs.

GPP Guidelines Online Course
AVAC and partners offer a number of different GPP trainings.
The primary GPP Online Training Course provides community engagement coordinators and managers, advocates working with communities, and research implementers a foundational knowledge of the GPP guidelines, a deeper understanding of how to build sustainable relationships with community and broader stakeholders, and guides learners through a process of developing a GPP plan for their own context. Information coming soon!
Tools for GPP Implementation
These supplementary tools support researchers and other stakeholders to conduct in-person GPP trainings, implement the guidelines, and monitor conduct of GPP programs the GPP guidelines.
GPP Publications
The GPP guidelines have been the subject of several landmark peer reviewed articles, and featured in numerous articles and publications exploring the challenges and opportunities of implementing GPP throughout a research trial. Click here to explore more.
Impact
GPP and stakeholder engagement has shifted trial design and approaches – for the better
- The CAPRISA research center in South Africa has built a long-standing relationship with the community, independent of trials, including providing benefits such as support to local schools. This has resulted in increased trust by the community, who provides honest insight into how members perceive and participate in trials.
- Gilead, a drug company, amended the protocol of an efficacy trial for a next-generation PrEP product and created new advisory mechanisms after receiving feedback from concerned advocates about the trial’s design and lack of community engagement.
- The Microbicide Trials Network conducted wide stakeholder engagement for MTN 017, the first ever global rectal microbicide study. The network has stated that participation, adherence, and thus trial results benefited from trust built within communities and amongst national stakeholders through their GPP consultation processes.
- Adapted beyond HIV to four other disease and research areas
Adaptations of GPP to other disease areas
- In 2021, AVAC launched Essential Principles & Practices for GPP Compliance: Engaging stakeholders in biomedical research during the era of COVID-19, to help guide stakeholder engagement in COVID-19 research
- In 2017, Aeras adapted GPP to TB Vaccine research and published Good Participatory Practice Guidelines for TB Vaccine Research
- The World Health Organization published Good Participatory Practice Guidelines for Trials of Emerging Pathogens in 2016
- Critical Path to TB Drug Regimens adapted AVAC’s GPP to develop Good Participatory Practice guidelines for TB Drug Trials in 2012
- In 2012, Thai Treatment Action Group published Stakeholder Input and Recommendations for Good Participatory Practices in Biomedical HIV Prevention Trials in Thailand
US President Barack Obama’s Commission for the Study of Bioethical Issues referenced GPP as a key resource for ensuring ethical research in its 2011 report.
