A Study of Combination Treatment With an HCV Polymerase Inhibitor (RO5024048) and an HCV Protease Inhibitor (RO5190591) in Genotype 1 Chronic Hepatitis C Patients - Full Text View

Sponsored by:	Hoffmann-La Roche
Information provided by:	Hoffmann-La Roche
ClinicalTrials.gov Identifier:	NCT00801255

Purpose

This 4 cohort study will evaluate the efficacy and safety of combination treatment with an HCV polymerase inhibitor(RO5024048)and an HCV protease inhibitor(RO5190591) in patients with chronic hepatitis C, genotype 1. Cohorts A and B are designed to evaluate doses of 500mg po bid RO5024048 and 100mg po q8h RO5190591, alone or in combination, for up to 7 or 14 days. if supported by safety data from the first 2 cohorts, cohorts C and D are designed to evaluate combination treatment with up to 1000mg po bid RO5024048 and up to 200mg q8h RO5190591 for 14 days. The anticipated time on study treatment is <3 months, and the target sample size is <100 individuals.
