Final Results to be Presented in the Fall
Foster City, CA -- June 30, 1998
Gilead Sciences, Inc. (Nasdaq: GILD) announced today the preliminary results of four Phase II/III clinical trials to test the efficacy and safety of GS 4104, the first oral neuraminidase inhibitor for influenza A and B, developed jointly by Gilead and F. Hoffmann-La Roche. GS 4104 was evaluated in international Phase II/III field trials, which enrolled over 2,900 people, during the 1997-1998 Northern Hemisphere flu season.
Preliminary data show that the trials appear to have met clinical expectations for the treatment and prevention of influenza. Early results indicate statistically significant differences between active and placebo arms for all primary endpoints, which included time to resolution of clinical symptoms in each of two treatment studies and the incidence of laboratory confirmed clinical influenza in two combined prophylaxis studies. The drug was well tolerated by the patients enrolled in these studies.
Based upon these encouraging results, Roche and Gilead are continuing the development program to support registration filings, anticipated in 1999. Final data are currently being analyzed. The companies plan to submit the complete results of the trials for presentation at the Interscience Conference on Antimicrobial Agents and Chemotherapy (September 24 - 26, San Diego), and the Infectious Diseases Society of America Conference (November 11 - 14, Denver).
