Gilead Files European Marketing Application for the Quad, a Once-Daily Single-Tablet Regimen for the Treatment of HIV Infection

FOSTER CITY, Calif.--(BUSINESS WIRE)--Dec. 20, 2011-- Gilead Sciences, Inc. (Nasdaq:GILD) announced today that the Marketing Authorisation Application (MAA) for the Quad single-tablet regimen of elvitegravir, cobicistat, emtricitabine and tenofovir disoproxil fumarate for the treatment of HIV-1 infection in adults, submitted on November 24, 2011, has been validated by the European Medicines Agency (EMA). Review of the MAA will be conducted under the centralized licensing procedure, which, when finalized, provides one marketing authorization in all 27 member states of the European Union (EU).

“Based on the safety and efficacy data from the Phase 3 pivotal studies, we believe the Quad single-tablet regimen has the potential to be a convenient treatment option for patients new to HIV therapy,” said Norbert Bischofberger, PhD, Executive Vice President, Research and Development and Chief Scientific Officer, Gilead Sciences. “We look forward to working with European regulatory authorities to bring this new single-tablet regimen to physicians and patients as quickly as possible.”

The MAA for the Quad is supported by results from two Phase 3 studies (Study 102 and Study 103). The MAA is also supported by clinical data for the individual components of the Quad and Chemistry, Manufacturing and Controls (CMC) information on the individual components of the Quad and the co-formulated single-tablet regimen. Gilead submitted a U.S. regulatory application for the Quad in October 2011.

Gilead's first single-tablet regimen, Atripla® (efavirenz 600 mg/emtricitabine 200 mg/tenofovir disoproxil fumarate 300 mg), was approved in the EU in 2007 and is marketed in partnership with Bristol-Myers Squibb and Merck & Co. The company’s second single-tablet regimen, Eviplera® (emtricitabine/rilpivirine/tenofovir disoproxil fumarate), which combines Gilead’s Truvada® (emtricitabine/tenofovir disoproxil fumarate) and Tibotec Pharmaceuticals’ rilpivirine, was approved in the EU in November 2011.

About the Quad

The Quad contains four Gilead compounds in a complete once-daily, single-tablet regimen: elvitegravir; cobicistat, a “boosting” agent that enables elvitegravir once-daily dosing; and Truvada.

About Elvitegravir

Elvitegravir is an integrase inhibitor. Unlike other classes of antiretroviral agents, integrase inhibitors interfere with HIV replication by blocking the ability of the virus to integrate into the genetic material of human cells. Elvitegravir was licensed by Gilead from Japan Tobacco Inc. (JT) in March 2005. Under the terms of Gilead’s agreement with JT, Gilead has exclusive rights to develop and commercialize elvitegravir in all countries of the world, excluding Japan, where JT retains rights.

About Cobicistat

Cobicistat is Gilead's proprietary potent mechanism-based inhibitor of cytochrome P450 3A (CYP3A), an enzyme that metabolizes drugs in the body.

The Quad, elvitegravir and cobicistat are investigational products and their safety and efficacy have not yet been established.
