Overview
Brief Summary
To establish a new treatment option for treatment-naïve participants with HIV-1, the efficacy and safety of doravirine will be determined relative to a protease inhibitor (PI). Participants will receive double-blind treatment during the 96-week Base Study. Eligible participants in either of the Base Study groups will continue to receive the doravirine-containing regimen open label for an additional 96 weeks in the Study Extension 1. Eligible participants who are deriving benefit will continue in Study Extension 2 to receive the doravirine-containing regimen open label until doravirine becomes locally available or for an additional 96 weeks, whichever comes first. The primary hypothesis is that doravirine 100 mg once a day (q.d.) is non-inferior to darunavir/ritonavir (800 mg/100 mg) q.d., each in combination with TRUVADA™ or EPZICOM™/KIVEXA™, as assessed by the proportion of participants with HIV-1 ribonucleic acid (RNA) <50 copies/mL at Week 48. If non-inferiority is established, then the superiority of doravirine 100 mg q.d. compared to darunavir/ ritonavir (800 mg/100 mg) q.d. will be assessed.
Detailed Description
Participants in Australia, Russia, and South Africa who are deriving benefit from MK-1439A are also eligible to continue receiving study drug during Study Extension 3, which will last for 2 years or until drug is available locally, whichever comes first.
