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 open-label rollover phase to receive cobicistat and attend visits every 12 weeks until it becomes commercially available, or until Gilead Sciences elects to terminate development of cobicistat.

|Official Title:||A Phase 3b, Open-Label, Single Arm Study to Evaluate the Safety and Efficacy of Cobicistat-boosted Darunavir Plus Two Fully Active Nucleoside Reverse Transcriptase Inhibitors in HIV-1 Infected, Antiretroviral Treatment-Naïve and -Experienced Adults With No Darunavir Resistance-associated Mutations|
|Study Start Date :||September 2011|
|Actual Primary Completion Date :||August 2012|
|Actual Study Completion Date :||October 2015|
Experimental: COBI-boosted DRV
Participants will receive DRV+COBI+2 investigator-selected NRTIs for 48 weeks, and may continue their regimen in the open-label rollover phase.
150 mg tablet administered orally with food once daily
800 mg (2 x 400 mg tablets) administered orally with food once daily
Participants will receive 2 nucleoside analogue reverse transcriptase inhibitors (NRTIs) selected by the investigator after resistance testing at screening and administered according to prescribing information. NRTIs may include emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF), zidovudine+FTC/TDF, abacavir (ABC)+TDF, ABC+FTC/TDF, ABC+lamivudine (3TC), or didanosine (DDI)+FTC.
