Study Details

Study Description

Brief Summary

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.

Condition or Disease Intervention/Treatment Phase
  • Drug: TRUVADA + raltegravir
Phase 4

Detailed Description

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.

    Study Results

    Participant Flow

    Recruitment Details Participants were recruited from Fenway Health. Patients at least 18 years of age, who contacted Fenway Health and presented within 72 hours after a potential sexual exposure to HIV-1 were asked to participate in this study.
    Pre-assignment Detail If study coordinator is notified more than 72 hours after exposure occurred, person will not be eligible for study participation; however they will be referred to an on call medical provider for Non Occupational Post-Exposure Prophylaxis evaluation.
