Researchers will discontinue one arm of the VOICE study testing oral tenofovir (Viread) pills after an interim analysis by an independent monitoring board showed that the trial would be unlikely to show that the drug works better than placebo for pre-exposure prophylaxis (PrEP) to prevent HIV infection. Other study arms testing the tenofovir/emtricitabine combination pill (Truvada) and a tenofovir vaginal gel will continue. No safety concerns were identified.

Among the major studies presented, Robert Grant from the Gladstone Institute of the University of California at San Francisco described final data from the iPrEx trial, which showed that pre-exposure prophylaxis (PrEP) using tenofovir/emtricitabine (Truvada) reduced new HIV infections by 42% overall, and by more than 90% among people who demonstrated good adherence.
