A Study Evaluating Slow Response/Non-Rapid Response in Patients With Chronic Hepatitis C, Genotype 1, 2, 3 & 4 Treated With Pegasys (Peginterferon Alfa-2a) and Copegus (Ribavirin)

December 20, 2017 updated by: Hoffmann-La Roche

A Multi-Center Study Evaluating the Rate of Genotype 1, 2, 3 & 4 Chronic Hepatitis C Patients With Slow Response / Non-rapid Viral Response to Anti-Viral Treatment of Pegasys (Peginterferon Alfa 2a) in Combination With Copegus (Ribavirin)

This multi-center study will evaluate the viral response in patients with chronic hepatitis C, genotype 1, 2, 3 & 4 on standard anti-viral treatment with Pegasys (peginterferon alfa-2a) and Copegus (ribavirin). Patients will receive weekly subcutaneous Pegasys plus daily oral Copegus for 24 weeks (genotype 2 & 3) or 48 weeks (genotype 1 & 4). Patients identified as slow responders/non-rapid virological responders will be eligible for an additional 24 weeks of treatment.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Percentage of Participants With Partial Early Virological Response (pEVR) to Study Treatment
Time Frame: Week 12
The rate of participants with pEVR to study treatment was defined as ≥ 2 log reduction in HCV-RNA level from baseline value to Week 12 of study treatment but with detectable HCV-RNA at Week 12.

Week 24
Percentage of Participants With Rapid Virologic Response (RVR) at Week 4
Time Frame: Week 4
The rate of participants with RVR was defined as negative HCV-RNA level at Week 4 of study treatment.
Week 4
Percentage of Participants Without a RVR (Non-RVR) at Week 4 of Standard Treatment
Time Frame: Week 4
The rate of participants without a RVR (non-RVR) was defined as detectible HCV-RNA level at Week 4 of standard treatment.
Week 4
Percentage of Participants With Non-RVR and Undetectable HCV-RNA at Week 24
Time Frame: Week 24
The rate of participants with non-RVR and undetectable HCV-RNA at Week 24 was defined as detectable HCV-RNA level at Week 4 of study treatment and undetectable HCV-RNA at Week 24 of study.
Week 24

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
Measure Description

Percentage of Participants With pEVR to Study Treatment at Week 12
Time Frame: Week 12
The rate of participants with pEVR to study treatment was defined as ≥ 2 log reduction in HCV-RNA level from baseline value to Week 12 of study treatment but with detectable HCV-RNA at Week 12.
Week 12
Percentge of Participants With a cEVR to Study Treatmen at Week 12 of Study Treatment
Time Frame: Week 12

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.
