                  Gilead 
                    Sciences Refiles New Drug Application with the FDA for Single-Tablet 
                    Regimen of Truvada and TMC278
 
 
                
                  Foster 
                    City, Calif. -- February 10, 2011 -- Gilead Sciences, Inc. 
                    (Nasdaq:GILD) announced today that it has refiled a New Drug 
                    Application (NDA) with the U.S. Food and Drug Administration 
                    (FDA) for the single-tablet regimen of Truvada (emtricitabine 
                    and tenofovir disoproxil fumarate) and Tibotec Pharmaceuticals' 
                    investigational non-nucleoside reverse transcriptase inhibitor 
                    TMC278 (rilpivirine hydrochloride) for HIV-1 infection in 
                    adults. 
                
                  Gilead previously submitted an NDA for the single-tablet regimen 
                    of Truvada/TMC278 on November 23, 2010. The company announced 
                    on January 25, 2011 that it had received a "refuse to 
                    file" notification from the FDA regarding that submission. 
                    Specifically, the FDA requested additional information on 
                    the analytical methodology and qualification data used to 
                    establish acceptable levels of recently identified degradants 
                    related to emtricitabine; this information has been included 
                    in the refiling.
 
                
                  The FDA has up to 60 days to conduct a preliminary review 
                    to assess whether the NDA is sufficiently complete to permit 
                    a substantive review. The FDA will establish a target action 
                    date for the NDA, under the Prescription Drug User Fee Act 
                    (PDUFA), if the application is formally filed.
