IAS 2013: PrEP Shown Effective for Injection Drug Users [VIDEO]

Researchers at the 7th International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention (IAS 2013) this month in Kuala Lumpur provided further details from the Bangkok Tenofovir Study, which showed that tenofovir pre-exposure prophylaxis, or PrEP, reduced the risk of HIV infection among people who inject drugs.

As described last month in The Lancet, the trial found that daily tenofovir (Viread) reduced the risk of HIV infection among injection drug users by 49% overall and by more than 70% among participants who took tenofovir via directly observed therapy. But the study could not determine whether PrEP worked by preventing infections due to needle-sharing or sex.

Michael Martin from the U.S. Centers for Disease Control and Prevention presented further data on adherence and drug levels in the Bangkok trial. He summarized the findings at a press conference prior to his late-breaker presentation.
