Abstract
The challenge of designing future HIV prevention efficacy trials in a rapidly evolving HIV prevention landscape was explored through a series of virtual stakeholder's engagement meetings convened online between October 2020 and April 2021. A broad array of stakeholders from the HIV prevention research community reviewed current trial designs and lessons learned, explored issues specific to unique product classes, and concluded with specialist-focused examinations of statistical design concepts and the importance of community engagement in research. The aim was to reflect on current approaches and evaluate new trial design approaches for evaluating efficacy of a candidate prevention strategy in the context of an active-controlled trial, which does not include a placebo arm. In this report, we provide a summary of the discussion points that included gaps in understanding and logical next steps in the prevention research pathway. The technical challenges involved in the statistical design approaches are described in a companion article.
