GLASGOW, England--(BUSINESS WIRE)--Gilead Sciences (Nasdaq:GILD) today announced two-year (96-week) results from two pivotal Phase 3 studies (Studies 102 and 103) evaluating the company’s newest single tablet HIV regimen, StribildTM (elvitegravir 150 mg/cobicistat 150 mg/emtricitabine 200 mg/tenofovir disoproxil fumarate 300 mg), among treatment-naïve patients with HIV-1 infection.

These results were presented today in an oral session at the 11th International Congress on Drug Therapy in HIV Infection (HIV11) in Glasgow, United Kingdom.
