FOSTER CITY, Calif.--(BUSINESS WIRE)--Gilead Sciences, Inc. (Nasdaq:GILD) today announced an expansion to its agreement with Janssen R&D Ireland for the development and commercialization of a new once-daily single tablet regimen containing Gilead’s tenofovir alafenamide (TAF) and emtricitabine, and Janssen’s rilpivirine. The original agreement was established in 2009 for the development and commercialization of Complera®, marketed as Eviplera® in the European Union, which combines tenofovir disoproxil fumarate, emtricitabine and rilpivirine in a once-daily tablet. Gilead will initiate Phase 3 studies of emtricitabine/rilpivirine/TAF in the coming months. Pending the product’s approval, Gilead will be responsible for the manufacturing, registration, distribution and commercialization of the regimen in most countries, while Janssen will distribute in approximately 17 markets.
TAF is a novel nucleotide reverse transcriptase inhibitor that has demonstrated high antiviral efficacy at a dose 10 times lower than Gilead’s Viread® (tenofovir disoproxil fumarate), as well as an improved renal and bone safety profile.
“We believe that TAF’s efficacy and safety advantages may make it a strong backbone of new fixed-dose combinations and single tablet regimens,” said Norbert Bischofberger, PhD, Executive Vice President, Research and Development and Chief Scientific Officer, Gilead Sciences. “Gilead is pleased to continue its collaboration with Janssen to bring improved treatment options to patients living with HIV.”
Gilead and Janssen also have amended a licensing agreement for the development and commercialization of a once-daily single tablet regimen for HIV containing Gilead’s TAF, emtricitabine and cobicistat, and Janssen’s darunavir. Under the amended agreement, Janssen will be responsible for further development of the regimen and, subject to regulatory approval, the manufacturing, registration, distribution and commercialization of the product worldwide.
Separate to the Janssen agreements, Gilead is advancing its own TAF-based single tablet regimen containing elvitegravir, cobicistat, emtricitabine and TAF. The company announced on November 6, 2014, it filed for regulatory approval in the United States.
TAF and TAF-based regimens are investigational products in the United States and have not yet been determined safe or efficacious in humans.

This press release includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that are subject to risks, uncertainties and other factors, including risks related to whether ongoing clinical trials of TAF-based combinations will be successful and Gilead’s ability to coformulate new single tablet regimens containing TAF, emtricitabine and rilpivirine, and TAF, emtricitabine, cobicistat and darunavir. In addition, Gilead and Janssen may make a strategic decision to discontinue development of the TAF combination products if, for example, the market for the products fails to materialize as expected. As a result, the agreements may terminate. Further, regulatory authorities may not approve TAF-based regimens, and marketing approvals, if granted, may have significant limitations on their use. As a result, TAF combination products may never be successfully commercialized.
