FDA approves first pill to help prevent HIV

BY MATTHEW PERRONE, AP HEALTH WRITER

WASHINGTON -- The Food and Drug Administration on Monday approved the first drug shown to reduce the risk of HIV infection, a milestone in the 30-year battle against the virus that causes AIDS.

The agency approved Gilead Sciences' pill Truvada as a preventive measure for people who are at high risk of acquiring HIV through sexual activity, such as those who have HIV-infected partners.

Public health advocates say the approval could help slow the spread of HIV, which has held steady at about 50,000 new infections per year for the last 15 years. An estimated 1.2 million Americans have HIV, which develops into AIDS unless treated with antiviral drugs. With an estimated 240,000 HIV carriers unaware of their status, doctors and patients say new methods are needed to fight the spread of the virus.

Gilead Sciences Inc. has marketed Truvada since 2004 as a treatment for people who are already infected with the virus.

But starting in 2010, studies showed that the drug could actually prevent people from contracting HIV when used as a precautionary measure. A three-year study found that daily doses cut the risk of infection in healthy gay and bisexual men by 42 percent, when accompanied by condoms and counseling.
