Gilead Outlines R&D Priorities for 2009
"Gilead's R&D program is more extensive today than at any time in our 21-year history," said Norbert Bischofberger, PhD, Executive Vice President, Research and Development and Chief Scientific Officer, Gilead Sciences. "As we enter 2009, we have multiple product candidates in our development pipeline including several programs in or about to enter Phase III and Phase II studies. Our efforts are highly targeted to a select range of therapeutic areas, where we believe we are strongly positioned to advance candidates with the potential to be best-in-class treatments."
Highlights of Gilead's R&D program for 2009 include:
Advancing a New Single Tablet Regimen for HIV
Gilead is developing elvitegravir, an investigational integrase inhibitor for use in HIV-infected, treatment-experienced patients; GS 9350, a novel pharmacoenhancer (or "booster"); and a "four-in-one" fixed-dose regimen (FDR) for HIV-infected, treatment-naive patients that combines elvitegravir, GS 9350, tenofovir disoproxil fumarate and emtricitabine. Currently, the only available complete single tablet regimen is Atripla(R) (efavirenz 600 mg/emtricitabine 200 mg/tenofovir disoproxil fumarate 300 mg), which is jointly marketed in the United States, Canada and Europe by Gilead and Bristol-Myers Squibb Company and distributed by Merck & Co., Inc. in 94 resource-limited countries. Atripla is the most-prescribed HIV treatment regimen in the United States. Gilead's once-daily formulation of Truvada also contains emtricitabine (200 mg) and tenofovir disoproxil fumarate (300 mg) and must be taken with at least one other antiretroviral.
Advancing Therapy for Liver Disease
GS 9450, Gilead's lead product candidate for serious liver disease, is a novel, once-daily caspase inhibitor for inflammatory and fibrotic conditions including HCV and nonalcoholic steatohepatitis (NASH). NASH is a disease characterized by liver inflammation caused by a buildup of fat in the liver. The condition has been linked to obesity, high cholesterol and diabetes, and the National Center of Infectious Diseases predicts that by 2025 more than 25 million Americans may be affected.
Expanding Presence in the Cardiovascular Arena
The company's lead investigational candidate in the field of cardiovascular medicine is darusentan, an oral endothelin receptor antagonist (ERA), for resistant hypertension. Resistant hypertension affects approximately 2-3 million Americans who fail to reach target blood pressure despite taking optimal doses of a three-drug anti-hypertension regimen that includes a diuretic.
Defining Priorities for Respiratory Pipeline
Gilead continues to focus on development efforts for aztreonam lysine for inhalation and ambrisentan for IPF, while also exploring the potential of GS 9310/11 for cystic fibrosis (CF) and GS 9411 for the treatment of pulmonary disease.
The medications discussed in this press release are investigational therapies 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 the risks related to our ability to initiate a Phase II trial of our FDR for HIV infection in treatment-naive HIV patients, a Phase IIb trial of GS 9450 for fibrotic conditions, a Phase II trial of cicletanine for PAH, a Phase III study evaluating ambrisentan for IPF, each in the timelines currently anticipated; our ability to enroll patients in our clinical trials as planned; our ability to conclude clinical trials and obtain data in the timelines currently anticipated; the possibility of unfavorable results of the clinical trials, the need to modify or delay our clinical trials or to perform additional trials and the risk of failing to obtain FDA and other regulatory body approvals. As a result, our product candidates, including GS 9350, GS 9450, GS 9190, darusentan, cicletanine, ambrisentan, aztreonam lysine for inhalation, GS 9310/11 and GS 9411 may never be successfully commercialized. Further, we may make a strategic decision to discontinue development of any of our product candidates, if, for example, we believe commercialization will be difficult relative to other opportunities in our pipeline. These risks, uncertainties and other factors could cause actual results to differ materially from those referred to in the forward-looking statements. The reader is cautioned not to rely on these forward-looking statements. These and other risks are described in detail in Gilead's Annual Report on Form 10-K for the year ended December 31, 2007 and its Quarterly Report on Form 10-Q for the first, second and third quarters of 2008, 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.
