A Study of RO5024048 in Combination With Pegasys and Copegus in Treatment-Naive Patients With Chronic Hepatitis C, Genotype 1 or 4

November 1, 2016 updated by: Hoffmann-La Roche

A Randomized, Double-blind, Multicenter, Dose and Duration Finding Study to Evaluate the Sustained Virologic Response of the HCV Polymerase Inhibitor Prodrug (RO5024048) in Combination With Pegasys® and Ribavirin® (SOC) Versus SOC in Treatment-Naïve Patients With HCV Genotype 1 or 4 Infection

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.

Conditions

Conditions

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Sustained virologic response: Percentage of patients with undetectable Hepatitis C RNA level
Time Frame: 24 weeks after end of treatment
24 weeks after end of treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Virologic response: Percentage of patients with undetectable Hepatitis C RNA level
Time Frame: 60 Weeks
60 Weeks
Virologic response: Percentage of patients with undetectable Hepatitis C RNA level

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
