FOSTER CITY, Calif. Gilead Sciences has started a late-stage clinical trial of an investigational 4-in-1 treatment for HIV, the drug maker said.
Gilead announced the initiation of a phase 3 trial of its “Quad” HIV drug, a single-tablet treatment that combines elvitegravir, cobicistat, emtricitabine and tenofovir disoproxil fumarate. The study will compare the Quad regimen with the standard of care among adults with HIV-1 who have not taken antiretroviral treatments. The company is also investigating cobicistat as a standalone boosting agent for antiretroviral drugs.
“We are pleased to announce that the Quad phase 3 clinical program is underway,” Gilead EVP research and development and chief scientific officer Norbert Bischofberger said. “Efficacy and safety results from the phase 2 study suggest that the Quad may represent an important new option for patients with HIV.”
