HIV Non Occupational Post-Exposure Prophylaxis (PEP)
A Phase IV Open-Label Evaluation of Safety, Tolerability and Patient Acceptance of Raltegravir (MK-0518) Combined With a Fixed-Dose Formulation of Tenofovir Following Potential Exposure to HIV-1
This study will evaluate how safe and tolerable a combination of taking three-drugs will be for the purpose of preventing HIV transmission after a high-risk sexual contact exposure in HIV uninfected adults.
This study will evaluate a three drug regimen in the form of two pills which will be taken for 28 days for the prevention of HIV infection. Two drugs are combined in an FDA-approved pill called TRUVADA, containing the HIV medications, tenofovir disoproxil fumarate 300mg and emtricitabine 200mg, taken as one pill once a day. The third drug is a new formulation, raltegravir 400mg pill taken twice a day.
