Multi-Center, Randomized, Open-Label Study of G/P +/- RBV for NS5A + SOF Previously Treated GT1 HCV Subjects
February 17, 2020 updated by: University of Florida
A Phase 3b, Multi-Center, Randomized, Open-Label, Pragmatic Study of Glecaprevir/Pibrentasvir (G/P) +/- Ribavirin for GT1 Subjects With Chronic Hepatitis C Previously Treated With an NS5A Inhibitor + Sofosbuvir Therapy
The study will enroll well-compensated cirrhotic as well as non-cirrhotic subjects treatment experienced with an NS5a Inhibitor + sofosbuvir and will include patients who did not complete the prescribed duration due to adverse event or any reason other than for non/poor compliance.
Subjects will be randomized to 12 or 16 weeks of treatment.

Detailed Description
The primary purpose of this study is to compare the efficacy and safety of glecaprevir and pibrentasvir (G/P) for 12 weeks to G/P for 16 weeks in non-cirrhotic NS5A (non-structural protein 5a)-inhibitor plus sofosbuvir ± RBV (Ribavirin) treatment-experienced adults with HCV genotype 1 (GT1) infection, and to compare the efficacy and safety of G/P with RBV for 12 weeks to G/P without RBV for 16 weeks in NS5A-inhibitor plus sofosbuvir (SOF) ± RBV treatment-experienced adults with compensated cirrhosis and GT1 infection.
