Enanta announced results from AbbVie’s pivotal Phase 3 TURQUOISE-II study of the investigational three direct-acting (3D) antiviral regimen for genotype 1 (GT1) chronic hepatitis C virus (HCV) infection with compensated liver cirrhosis. The investigational regimen consists of a fixed-dose combination of boosted protease inhibitor ABT-450/ritonavir, NS5A inhibitor ABT-267, and non-nucleoside polymerase inhibitor ABT-333 with or without ribavirin.
TURQUOISE-II is a global, multi-center, randomized, open-label study evaluating the efficacy and safety of 12 weeks or 24 weeks of treatment with AbbVie’s three direct-acting antiviral regimen with ribavirin (RBV) in adult patients. Patients in the study were either new to therapy or treatment-experienced.
