US health advisers on Thursday urged regulators to approve Truvada, made by Gilead Sciences, as the first preventive pill against HIV/AIDS instead of just a treatment for infected people. The favorable vote came after clinical trials showed Truvada could lower the risk of HIV in gay men by 44 to 73 percent, and was hailed by some AIDS advocates as a potent new tool against human immunodeficiency virus. However, many concerns were raised during a marathon 11-hour panel meeting in which about three dozen health care providers warned that the pill could boost risky behaviors and possibly lead to a drug-resistant strain of HIV. The Food and Drug Administration is not bound by the recommendations of its expert panel, but usually follows the advice. A final decision by the FDA is expected by June 15. Mitchell Warren, executive director of HIV prevention group AVAC, said after the vote that pre-exposure prophylaxis (PrEP), or the method of taking a drug ahead of potential exposure to HIV, “while not a panacea, will be an essential additional part to the world’s success in ending AIDS.”
