Primary Outcome Measures:
  • Medication Regimen Completion Rates [ Time Frame: 28 days ]
    Pill counts performed at 14 and 28 days

  • Number of HIV-1 Infected Participants [ Time Frame: 90 days ]
    Of participants that were evaluable at 3 months post initiation of treatment, how many became HIV-1 infected


Enrollment: 100
Study Start Date: February 2008
Study Completion Date: August 2010
Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Group 1
TRUVADA + raltegravir
Drug: TRUVADA + raltegravir
TRUVADA (tenofovir disoproxil fumarate (DF) 300mg + emtricitabine 200mg) + RALTEGRAVIR 400mg
Other Names:
  • tenofovir DF
  • emtricitabine

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.
