FOSTER CITY, Calif.--(BUSINESS WIRE)--Gilead Sciences, Inc. (Nasdaq:GILD) announced Phase II clinical trial results today showing that its investigational fixed-dose single-tablet “Quad” regimen of elvitegravir, GS 9350 (cobicistat) and Truvada® (emtricitabine and tenofovir disoproxil fumarate) for the treatment of HIV infection exhibited antiretroviral activity comparable to that of Atripla® (efavirenz 600 mg/ emtricitabine 200 mg/ tenofovir disoproxil fumarate 300 mg). At 24 weeks, the proportion of patients who achieved HIV RNA (viral load) less than 50 copies/mL was 90 percent in the Quad arm and 83 percent in the Atripla arm (using an analysis where missing equals failure, intent-to-treat population). Discontinuation rates due to adverse events were comparable in both arms of the study. These data will be presented today at the 17th Conference on Retroviruses and Opportunistic Infections (CROI) in San Francisco (Abstract #58LB).
