FOSTER CITY, Calif.--(BUSINESS WIRE)--Gilead Sciences, Inc. (Nasdaq: GILD) today announced that a Phase 2 clinical trial evaluating tenofovir alafenamide fumarate (TAF; formerly referred to as GS-7340), an investigational novel prodrug of tenofovir for the treatment of HIV-1 infection, met its primary objective. The ongoing study compares a once-daily single tablet regimen containing TAF 10 mg/elvitegravir 150 mg/cobicistat 150 mg/emtricitabine 200 mg with StribildTM (elvitegravir 150 mg/cobicistat 150 mg/emtricitabine 200 mg/tenofovir disoproxil fumarate 300 mg) among treatment-naïve adults. The TAF-based regimen achieved a similar virologic response to Stribild based on the proportion of patients with HIV RNA levels (viral load) of less than 50 copies/mL at 24 weeks of therapy (87 percent versus 90 percent, respectively).
