Summary
Brief summary
This multicenter, randomized, double-blind, parallel group study will evaluate the safety and
efficacy of the combination RO5024048 and ritonavir-boosted danoprevir with and without
Copegus (ribavirin) in patients with chronic hepatitis C genotype 1. In arm A and B,
interferon treatment-naïve patients will receive 1000 mg RO5024048 orally twice daily and 100
mg danoprevir with 100 mg ritonavir orally twice daily plus either Copegus (1000 mg or 1200
mg orally daily) or placebo for 12 weeks. Depending on viral response and treatment arm
patients will be re-randomized to continue assigned treatment for additional 12 weeks or stop
all treatment. The anticipated time on study treatment is up to 24 weeks plus a 24-week
follow-up.

As of 29. September 2011, Arm B patients (placebo-containing arm) will be offered, in
conjunction with the current treatment, Pegasys (peginterferon alfa-2a) 180 mcg
subcutaneously weekly plus Copegus 1000mg or 1200 mg orally daily for 24 weeks, with a
24-week follow-up.
