What are the Good Participatory Practice (GPP) Guidelines?
The Good Participatory Practice (GPP) Guidelines were developed by AVAC and UNAIDS. They provide trial funders, sponsors, and implementers with systematic guidance on how to effectively engage with all stakeholders in the design and conduct of biomedical HIV prevention trials. The guidelines are available in multiple languages. AVAC has also developed  an array of supplementary GPP tools tools.
