Merck Says Zepatier Tops Sovaldi Combo
Merck says that the C-EDGE comparative Phase 3 study of Zepatier (elbasvir and grazoprevir) versus a regimen of Gilead’s Sovaldi (sofosbuvir) plus peginterferon and ribavirin showed Zepatier superiority in treatment-experienced patients with chronic hepatitis C genotype 1 or 4 infection. FDA approved the drug 1/28 based in part on prior studies from the Phase 3 program.
The company describes Zepatier as a fixed-dose combination product containing elbasvir, a hepatitis C virus NS5A inhibitor, and grazoprevir, a hepatitis C virus NS3/4A protease inhibitor. It is indicated with or without ribavirin for treating chronic hepatitis C virus genotype 1 or 4 infection in adults.
