A Study of Mericitabine in Combination With Telaprevir and Pegasys/Copegus in Patients With Chronic Hepatitis C
A PHASE II, RANDOMIZED, DOUBLE-BLIND, MULTICENTER, PARALLEL GROUP STUDY TO EVALUATE THE SUSTAINED VIROLOGIC RESPONSE OF THE HCV POLYMERASE INHIBITOR PRODRUG RO5024048 IN COMBINATION WITH TELAPREVIR AND PEGASYS®/COPEGUS® IN PATIENTS WITH CHRONIC HEPATITIS C GENOTYPE 1 VIRUS INFECTION WHO WERE PRIOR NULL RESPONDERS TO TREATMENT WITH PEGYLATED INTERFERON/RIBAVIRIN

This randomized, double-blind, multi-center, parallel-group study will evaluate the sustained virologic response and the safety of mericitabine (RO5024048) in combination with telaprevir and Pegasys/Copegus in patients with chronic hepatitis C infection. The anticipated time on study treatment is up to 48 weeks.
