Truvada Approved to Reduce the Risk of Sexually Transmitted HIV in People Who Are Not Infected With the Virus

From U.S. Food and Drug Administration

July 16, 2012

On July 16, 2012, the Food and Drug Administration approved Truvada (a fixed dose combination of emtricitabine/tenofovir disoproxil fumarate) to reduce the risk of HIV infection in uninfected individuals who are at high risk of HIV infection and who may engage in sexual activity with HIV-infected partners.Truvada is to be used for pre-exposure prophylaxis (PrEP) in combination with safer sex practices to prevent sexually-acquired HIV infection in adults at high risk. Truvada is the first drug approved for this indication.

Truvada for PrEP is meant to be used as part of a comprehensive HIV prevention plan that includes risk reduction counseling consistent and correct condom use, regular HIV testing, and screening for and treatment of other sexually-transmitted infections. Truvada is not a substitute for safer sex practices

FDA previously approved Truvada (August, 2004) to be used in combination with other antiretroviral agents for the treatment of HIV-infected adults and children 12 years or older.

As part of PrEP, HIV-uninfected individuals who are at high risk will need to take Truvada daily to lower their chances of becoming infected with HIV should they be exposed to the virus. Again, PrEP indication means Truvada is approved for use as part of a comprehensive HIV prevention strategy that includes other prevention methods, such as safe sex practices, risk reduction counseling, and regular HIV testing.

As a part of this action, FDA is strengthening Truvada’s Boxed Warning to alert health care professionals and uninfected individuals that Truvada for PrEP must only be used by individuals who are confirmed to be HIV-negative prior to prescribing the drug and at least every three months during use to reduce the risk of development of resistant HIV-1 variants. The drug is contraindicated for PrEP in individuals with unknown or positive HIV status.

Truvada for PrEP is being approved with a Risk Evaluation and Mitigation Strategy (REMS). The central component of this REMS is a prescriber training and education program to assist prescribers in counseling and managing individuals who are taking or considering Truvada for PrEP. The training and education program will not restrict distribution of Truvada but will provide information about the important elements of a comprehensive HIV prevention strategy, the importance of adhering to the recommended daily dosing regimen, the serious risks of taking Truvada for PrEP if already infected with the virus or becoming infected with HIV while taking Truvada for the PrEP indication.

“The REMS for Truvada for the PrEP indication is aimed at educating health care professionals and uninfected individuals to help ensure its safe use for this indication without placing an unnecessary burden on health care professionals and patients who use Truvada for treating HIV infection.

Truvada’s safety and efficacy for PrEP were demonstrated in two large, randomized, double-blind, placebo-controlled clinical trials. The iPrEx trial evaluated Truvada in 2,499 HIV-negative men or transgender women who have sex with men and with evidence of high risk behavior for HIV infection, such as inconsistent or no condom use during sex with a partner of positive or unknown HIV status, a high number of sex partners, and exchange of sex for commodities. Results showed Truvada was effective in reducing the risk of HIV infection by 42 percent compared with placebo in this population. Efficacy was strongly correlated with drug adherence in this trial.
