Gilead announces results from Phase 3 trial evaluating sofosbuvir

Gilead Sciences announced that detailed results from four Phase 3 clinical trials evaluating sofosbuvir, the company's investigational once-daily nucleotide NS5B inhibitor for the treatment of chronic hepatitis C virus, or HCV infection, will be presented this week in oral sessions at the 48th Annual Meeting of the European Association for the Study of the Liver in Amsterdam, The Netherlands. In addition, detailed results from the four clinical studies have also been published online in two papers, ahead of print, in The New England Journal of Medicine. In the four trials, sofosbuvir was administered to nearly 1,000 patients with chronic HCV infection as part of an all-oral 12-week or 16-week treatment regimen in combination with ribavirin (RBV) in genotypes 2 and 3, or with RBV and pegylated interferon for 12 weeks in genotypes 1, 4, 5 and 6. Overall SVR12 rates (sustained viral response 12 weeks after completing therapy) from 50%-90% were observed.
