Bristol-Myers Squibb and Gilead Sciences Announce Licensing Agreement for Development and Commercialization of New Fixed-Dose Combination Pill for People Living with HIV
PRINCETON, N.J. & FOSTER CITY, Calif., Oct 26, 2011 (BUSINESS WIRE) -- Bristol-Myers Squibb Company /and Gilead Sciences, Inc. today announced a licensing agreement for Bristol-Myers Squibb to develop and commercialize a fixed-dose combination containing Bristol-Myers Squibb's protease inhibitor REYATAZ(R) (atazanavir sulfate) and Gilead's cobicistat, a pharmacoenhancing or "boosting" agent that increases blood levels of certain HIV medicines to potentially allow for one pill once daily dosing. Gilead is currently studying atazanavir and cobicistat in Phase 2 and 3 studies in HIV-1 treatment-naive patients.
REYATAZ is a prescription medicine used in combination with other medicines to treat people 6 years of age and older who are infected with the human immunodeficiency virus (HIV). REYATAZ should not be taken if patients are allergic to REYATAZ or to any of its ingredients.
Bristol-Myers Squibb will be responsible for the formulation, manufacturing, development, registration, distribution, and commercialization of the REYATAZ and cobicistat fixed-dose combination worldwide. Under the terms of the agreement, Bristol-Myers Squibb will pay Gilead an undisclosed royalty based on annual net sales of the product. Gilead retains sole rights for the manufacture, development and commercialization of cobicistat as a stand-alone product and for use in combination with other agents.
"This collaboration with Gilead builds on Bristol-Myers Squibb's longstanding commitment to develop medicines that have the potential to provide meaningful benefit to HIV patients, specifically aiming to enhance treatment options," said Elliott Sigal, M.D., Ph.D., Executive Vice President, Chief Scientific Officer & President, R&D, Bristol-Myers Squibb. "A REYATAZ and cobicistat fixed-dose combination has the potential not only to help simplify HIV therapy but also to address an unmet medical need in HIV for additional, innovative treatment options."
"Cobicistat provides us with the potential to co-formulate with a variety of commercially available HIV medicines that require boosting for optimal efficacy, such as the protease inhibitor atazanavir," said Norbert Bischofberger, Ph.D., Executive Vice President, Research and Development and Chief Scientific Officer, Gilead Sciences. "This agreement represents a shared commitment between Gilead and Bristol-Myers Squibb to develop multiple treatment options that can address individual patient needs."
Cobicistat is Gilead's proprietary potent mechanism-based inhibitor of cytochrome P450 3A (CYP3A), an enzyme that metabolizes drugs in the body. Cobicistat is an investigational product and has not yet been determined to be safe or efficacious in humans.
IMPORTANT INFORMATION About REYATAZ(R) (atazanavir sulfate)
INDICATION: REYATAZ(R) is a prescription medicine used in combination with other medicines to treat people 6 years of age and older who are infected with the human immunodeficiency virus (HIV). REYATAZ has been studied in a 48-week trial in patients who have taken anti-HIV medicines and a 96-week trial in patients who have never taken anti-HIV medicines.
REYATAZ does not cure HIV or lower your chance of passing HIV to others. People taking REYATAZ may still get opportunistic infections or other conditions that happen with HIV infection.
IMPORTANT SAFETY INFORMATION:
Do not take REYATAZ if you are allergic to REYATAZ or to any of its ingredients.
Do not take REYATAZ if you are taking the following medicines due to potential for serious, life-threatening side effects or death: Versed(R) (midazolam) when taken by mouth,Halcion(R) (triazolam), ergot medicines (dihydroergotamine, ergonovine, ergotamine, and methylergonovine such as Cafergot(R), Migranal(R), D.H.E. 45(R), ergotrate maleate, Methergine(R), and others), Propulsid(R) (cisapride), or Orap(R) (pimozide).

Bristol-Myers Squibb Forward Looking Statement
This press release contains "forward-looking statements" as that term is defined in the Private Securities Litigation Reform Act of 1995, regarding the research, development and commercialization of pharmaceutical products. Such forward-looking statements are based on current expectations and involve inherent risks and uncertainties, including factors that could delay, divert or change any of them, and could cause actual outcomes and results to differ materially from current expectations. No forward-looking statement can be guaranteed. Among other risks, there can be no guarantee that the compound described in this release will move from early stage development into full product development, that clinical trials of this compound will support a regulatory filing, or that the compound will receive regulatory approval or become a commercially successful product. Nor is there any guarantee that the transaction described in this release will receive the necessary regulatory approvals to close. Forward-looking statements in the press release should be evaluated together with the many uncertainties that affect Bristol-Myers Squibb's business, particularly those identified in the cautionary factors discussion in Bristol-Myers Squibb's Annual Report on Form 10-K for the year ended December 31, 2010, its Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K. Bristol-Myers Squibb undertakes no obligation to publicly update any forward-looking statement, whether as a result of new information, future events, or otherwise.
Gilead Sciences Forward Looking Statement
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 for cobicistat will be successful and the ability to formulate cobicistat with other agents, including atazanavir sulfate. In addition, safety and efficacy data from additional clinical trials may not warrant further development of cobicistat or the fixed-dose combination product, regulatory authorities may not approve cobicistat as a stand-alone product or in any combination product, and marketing approval, if granted, may have significant limitations on its use. As a result, cobicistat and the fixed-dose combination product may never be successfully commercialized. The parties may make a strategic decision to discontinue development of the fixed-dose combination product if, for example, Bristol-Myers Squibb is unable to successfully formulate the fixed-dose combination product or the market for the product fails to materialize as expected. These risks, uncertainties and other factors could cause actual results to differ materially from those referred to in the forward-looking statements. These and other risks are described in detail in Gilead's Quarterly Report on Form 10-Q for the quarter ended June 30, 2011, as filed with the U.S. Securities and Exchange Commission. All forward-looking statements are based on information currently available to Gilead, and Gilead assumes no obligation to update any such forward-looking statements.
