Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
This 6-arm study will assess the efficacy and safety of RO5024048 (R7128) in combination with
the approved doses of Pegasys (180micrograms sc weekly) + Copegus (1000/1200mg po daily)
(SOC), versus SOC in treatment-naive patients with chronic hepatitis C, genotype 1 and 4. The
first 3 groups will receive 1) RO5024048 500mg bid + Pegasys + Copegus for 12 weeks, followed
by SOC for 12 weeks; 2)RO5024048 1000mg bid + Pegasys + Copegus for 8 weeks, followed by SOC
for 16 weeks; 3) RO5024048 1000mg bid + Pegasys + Copegus for 12 weeks, followed by SOC for
12 weeks. After 24 weeks, patients in these 3 groups who have achieved rapid viral response
will stop treatment, and those who have not will receive SOC for a further 24 weeks. Group 4
will receive RO5024048 1000mg bid + Pegasys + Copegus for 12 weeks, followed by SOC for 36
weeks, and group 5 will receive SOC for 48 weeks. Group 6 provides retreatment on an
open-label basis for patients of Group 5 who failed treatment. Patients will receive
RO5024048 1000mg bid + Pegasys + Copegus for 24 weeks, followed by SOC for 24 weeks. The
anticipated time on study treatment is 6-12 months.
