NIAID Study Suggests Pre-Exposure Prophylaxis Reduces the Risk of HIV Infection Among MSM
“A daily dose of an oral antiretroviral drug, currently approved to treat HIV infection, reduced the risk of acquiring HIV infection by 43.8 percent among men who have sex with men. The findings, a major advance in HIV prevention research, come from a large international clinical trial published online Nov. 23 by the New England Journal of Medicine. The study, titled 'Chemoprophylaxis for HIV Prevention in Men,' found even higher rates of effectiveness, up to 72.8 percent, among those participants who adhered most closely to the daily drug regimen.
“‘We now have strong evidence that pre-exposure prophylaxis with an antiretroviral drug, a strategy widely referred to as PrEP, can reduce the risk of HIV acquisition among men who have sex with men, a segment of the population disproportionately affected by HIV/AIDS,’ says Anthony S. Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. ‘Additional research is needed, but certainly this is an important finding that provides the basis for further investigating, developing and employing this prevention strategy, which has the potential to make a significant impact in the fight against HIV/AIDS.’ …
“The study participants were randomly assigned to receive either a daily antiretroviral tablet containing combination emtricitabine (FTC 200 milligrams) and tenofovir (TDF 300 milligrams), known by the brand name Truvada, or a placebo pill. … In addition, all participants were routinely counseled about safe sex practices and provided condoms and treatment for other sexually transmitted infections. …
“Investigators will conduct a follow-on study in which all HIV-negative iPrEx participants will be offered the combination drug for 18 months. That study, which will begin in 2011, is designed to provide additional information about the drug’s long-term effectiveness and safety as well as participant risk behavior and pill-taking practices.”
