Primary Outcome Measures:
  • Efficacy as Assessed by the Number of Participants Who Were HIV Positive at 6 Months [ Time Frame: 6 months ]
    This measure assesses whether the combination of Truvada and Raltegravir prevents the acquisition of HIV at six months among HIV-negative people who have been exposed to HIV.

Secondary Outcome Measures:
  • Number of Participants Exhibiting Clinical or Laboratory Abnormalities Resulting From the 28-day Exposure to the Antiretroviral Drugs Being Explored in This Study [ Time Frame: 28 days ]
    Participants who experienced side effects categorized as grade 3 or higher by the Division of AIDS table for grading the severity of adult and pediatric adverse events were tested for clinical or laboratory abnormalities.

  • Safety and Tolerability as Assessed by the Number of Participants Who Completed the 28-day Course of the Antiretroviral Drugs Being Explored in This Study [ Time Frame: 28 days ]

Enrollment: 103
Study Start Date: May 2011
Study Completion Date: August 2015
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Truvada and Raltegravir
Single arm
Drug: Truvada
Tenofovir 200mg/emtricitabine 300mg once a day
Other Name: Tenofovir 200mg/emtricitabine 300mg
Drug: Raltegravir
Raltegravir 400mg twice a day
Other Name: Isentress

Detailed Description:

Non-Occupational Post-Exposure Prophylaxis (nPEP) after sexual exposure to HIV is recommended by the Centers for Disease Control (CDC). Although no efficacy data exist for Post-Exposure Prophylaxis (PEP) after sexual exposure, PEP has been shown to reduce HIV transmission in other exposure situations such as occupational exposures and mother-to-child transmission. The role in nPEP of the newer agents approved for the treatment of HIV infection remains unknown. The anti-HIV drug raltegravir works early in the life cycle of the virus, before it integrates with human DNA. It has few side effects and drug interactions what makes it an ideal drug for an nPEP regimen.

We aim to asses the safety and tolerability of the combination of truvada and raltegravir for nPEP.
