NCT01440569
First received: September 22, 2011

  Purpose

This study is to evaluate the safety and tolerability of cobicistat-boosted darunavir plus two fully active nucleoside analogue reverse transcriptase inhibitors in HIV 1 infected, antiretroviral treatment-naive and treatment-experienced adults with no darunavir (DRV) resistance-associated mutations.

After the Week 48 Visit, participants will be given the option to participate in an extension period to receive cobicistat and attend visits every 12 weeks until it becomes commercially available, or until Gilead Sciences elects to terminate development of cobicistat.

Primary Outcome Measures:
  • Percentage of Participants With Onset of Any Treatment-emergent Grade 3 or 4 Adverse Event Between Baseline and Week 24 [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percentage of Participants Achieving HIV-1 RNA < 50 Copies/mL at Week 24 (Snapshot Analysis) [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
  • Percentage of Participants Achieving HIV-1 RNA < 50 Copies/mL at Week 48 (Snapshot Analysis) [ Time Frame: Week 48 ] [ Designated as safety issue: No ]
  • Change From Baseline in CD4+ Cell Count at Week 24 [ Time Frame: Baseline; Week 24 ] [ Designated as safety issue: No ]
  • Change From Baseline in CD4+ Cell Count at Week 48 [ Time Frame: Baseline; Week 48 ] [ Designated as safety issue: No ]
  • Percentage of Participants Experiencing Any Treatment-emergent Adverse Event and Any Treatment-emergent Adverse Event Leading to Discontinuation of Study Drug Through Week 24 [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: No ]
  • Percentage of Participants Experiencing Any Treatment-emergent Adverse Event and Any Treatment-emergent Adverse Event Leading to Discontinuation of Study Drug Through Week 48 [ Time Frame: Up to 48 weeks ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: COBI-boosted DRV
Participants will receive DRV+COBI+2 investigator-selected NRTIs for 48 weeks, and may continue their regimen in the extension period.
Drug: COBI
Cobicistat (COBI) 150 mg tablet administered orally with food once daily
Other Names:
  • Tybost®
