An Observational Study of Dual and Triple Therapies Based on Pegasys (Peginterferon Alfa-2a) in Patients With Chronic Hepatitis C

Completed
Conditions
Hepatitis C, Chronic
Registration Number
NCT01604291
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This multi-center, observational study will evaluate the efficacy and safety of dual and triple therapies based on Pegasys (peginterferon alfa-2a) in patients with chronic hepatitis C. Patients receiving treatment with either Pegasys plus ribavirin or Pegasys plus ribavirin plus telaprevir/boceprevir will be observed for the duration of their treatment and for up to 24 weeks of follow-up.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Viral Response (SVR) at Week 24Week 24

The overall SVR-24 rate was defined as percentage of participants with Hepatitis C Virus Ribonucleic Acid (HCV-RNA) levels \< 50 International Units per MilliLiter (IU/mL) (as measured by Polymerase Chain Reaction (PCR)) at 24 weeks post treatment completion.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Extended RVRWeek 4 and 12 for telaprevir group; Week 8 and 24 for boceprevir group

Extended RVR was defined as HCV-RNA \<50 IU/mL at weeks 4 and 12 for participants treated with telaprevir; or at weeks 8 \& 24 for participants treated with boceprevir.

The assessment was performed in participants who received triple therapy in treatment arms 'Peginterferon Alfa-2a + Ribavirin +Telaprevir' and 'Peginterferon Alfa-2a + Ribavirin + Boceprevir'.

Time to First Dose Modification of Peginterferon Alfa-2aWeek 48
Percentage of Participants With End of Treatment Response (EoT)Week 24

End-of-Treatment (EoT) response was defined as HCV-RNA \<50 IU/mL by the end of treatment.

Treatment DurationWeek 48

The average amount of time a treatment was prescribed to participants.

Time to First Dose Modification of RibavirinWeek 48
Percentage of Participants Who Had SVR at Week 24 With Dose ModificationsWeek 24

Participants with dose modifications who had achieved SVR at Week 24 were reported. Data was collected for all participants who had dose modification of Peginterferon alfa-2a, Ribavirin or Telaprevir/boceprevir in any of the treatment regimen during the study.

Comparison of SVR at Week 24Week 24

SVR at Week 24 is compared by treatment group, type of infection, prior treatments and genotype.

Percentage of Participants With Rapid Virologic Response (RVR) at Week 4Week 4

RVR was defined as HCV-RNA \<50 IU/mL by Week 4

Time to First Dose Modification of Telaprevir/BoceprevirWeek 48
Number of Participants With SVR at Week 24 According to the Demographic CharacteristicsWeek 24

The overall SVR-24 rate was defined as percentage of participants with Hepatitis C Virus Ribonucleic Acid (HCV-RNA) levels \< 50 International Units per MilliLiter (IU/mL) (as measured by Polymerase Chain Reaction (PCR)) at 24 weeks post treatment completion. Number of participants analysed signifies participants who were evaluated for outcome measure. Data for this outcome measure was not summarized for each arm. Hence, data is reported for all participants.

Percentage of Participants With Complete Early Virologic Response (cEVR)Week 12

Complete early virologic response (cEVR) was defined as HCV-RNA \<50 IU/mL by Week 12

Percentage of Participants With Virologic RelapseWeek 72

Virologic relapse was defined as detectable HCV-RNA during the treatment-free follow-up period in participants with HCV-RNA \<50 IU/mL at EoT.

Mean Value of Hemoglobin in Participants With Treatment-Induced AnemiaWeek 48
Percentage of Participants With Adverse Events (AEs)Week 48

Any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

Safety analysis included 2 additional participants in arm 'Peginterferon Alfa-2a + Ribavirin + Telaprevir'. The safety parameters were analyzed by the treatment actually received by the participants.
