A Phase 3 interventional study of PI and RTV in Acquired Immunodeficiency Syndrome and HIV Infections, sponsored by Gilead Sciences. Completed at 99 sites in 12 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2016-06-08.
Sponsored by Gilead Sciences · Phase 3, Interventional, and Treatment
This study will evaluate the non-inferiority of Stribild® (elvitegravir/cobicistat/ emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF)) single-tablet regimen (STR) relative to regimens consisting of a protease inhibitor (PI) boosted with ritonavir (RTV) plus Truvada® (FTC/TDF) fixed-dose combination in maintaining HIV-1 RNA \< 50 copies/mL at Week 48 in virologically suppressed, HIV-1 infected adults. This study will also evaluate the safety, tolerability, and efficacy of the two regimens through 96 weeks of treatment.
4,258 studies on the registry are indexed under HIV Infections; 240 are open to participants now.
This study's enrollment of 438 is above the median of 83 across 3,250 interventional studies indexed under HIV Infections.
