NIH-Funded Study Finds Daily Dose of Antiretroviral Drug Reduces Risk of HIV

Today, the New England Journal of Medicine published research findings from the iPrEx study funded by the National Institutes of Health (NIH) and the Bill and Melinda Gates Foundation testing the efficacy of pre-exposure prophylaxis (PrEP). The study is a major step forward in our ability to prevent new HIV infections. The study found that a daily dose of an oral antiretroviral drug taken by HIV-negative gay and bisexual men and transgender women reduced the risk of acquiring HIV infection by 43.8 percent. The data showed even higher levels of protection from infection, up to 73 percent, among those participants who adhered most closely to the daily drug regimen.
