Designing the Next Generation of HIV Prevention Efficacy Trials: Synopsis of a 2018 Symposium

A one-day symposium was held in Seattle, Washington on November 5, 2018, including a broad array of stakeholders in the HIV prevention community. The topic of discussion was the challenge of designing future HIV prevention efficacy trials, given the multiplicity and speed of changes in the field in recent years, the development and rollout of effective prevention tools, and the resultant complexity in designing trials to evaluate new HIV prevention products. The goal was to identify potential statistical trial design approaches worthy of further investigation, as well as gaps in understanding and logical next steps. We overview the themes that emerged from the presentations, panels, and floor discussions, and outline initial next steps in further exploring design options.
