A Study of the Safety of Individualized Combination Therapy With Copegus (Ribavirin) and Pegasys (Peginterferon Alfa-2a) in Patients With Chronic Hepatitis C (MASTER)

November 1, 2016 updated by: Hoffmann-La Roche

Open-label, Multicenter, Non-Comparative Prospective Study to Assess the Safety of Individualized Combination Therapy With Ribavirin And Peginterferon Alfa-2a (40 kD) in Patients With Chronic Hepatitis C (CHC) (MASTER Study)

This open-label, non-comparative study will assess the safety and tolerability of individualized combination therapy with Copegus (ribavirin) and Pegasys (peginterferon alfa-2a) in patients with chronic hepatitis C. Patients with hepatitis C virus (HCV) genotype 1 (Group A) will receive Copegus 1'000 mg or 1'200 mg daily orally for 24-72 weeks. For patients with genotype 2 or 3 HCV (Group B) the Copegus dose will be 800 mg daily for 16-48 weeks. Patients who had previously received standard or pegylated interferons but were non-responders or with relapse (Group C) will receive Copegus 1'000 mg or 1'200 mg daily for up to 72 weeks. Concomitant therapy with Pegasys 180 mcg subcutaneously weekly will be given to all patients. Anticipated time on study treatment is up to 72 weeks with a 24-week follow-up.
