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

21. november 2018 oppdatert av: Hoffmann-La Roche

Multi-Center, Non-Interventional Study, on the Efficacy of Dual and Triple Therapies Based on Pegylated Interferon Alfa-2a for the Treatment of Chronic Hepatitis C Patients

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.

  • Receiving either dual therapy (Pegasys plus ribavirin) or triple therapy (Pegasys plus ribavirin plus telaprevir/boceprevir)
  • No contra-indications to Pegasys and ribavirin therapy or to treatment regimen containing protease inhibitor (telaprevir or boceprevir) as detailed in local Prescribing Information
  • Quantitative serum HCV RNA by PCR test before initiation of treatment

Exclusion Criteria:

  • Hepatitis A/B co-infection

Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Percentage of Participants With Sustained Viral Response (SVR) at Week 24
Tidsramme: Week 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.

Tiltaksbeskrivelse
Tidsramme
Comparison of SVR at Week 24
Tidsramme: Week 24
SVR at Week 24 is compared by treatment group, type of infection, prior treatments and genotype.
Week 24
Number of Participants With SVR at Week 24 According to the Demographic Characteristics
Tidsramme: Week 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.
Week 24
Percentage of Participants With Rapid Virologic Response (RVR) at Week 4

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'.
Week 4 and 12 for telaprevir group; Week 8 and 24 for boceprevir group
Percentage of Participants With Complete Early Virologic Response (cEVR)

Week 24
Percentage of Participants With Virologic Relapse
Tidsramme: Week 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.
Week 72
Treatment Duration
Tidsramme: Week 48
The average amount of time a treatment was prescribed to participants.

Percentage of Participants With Adverse Events (AEs)
Tidsramme: 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.

Percentage of Participants Who Had SVR at Week 24 With Dose Modifications
Tidsramme: Week 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.
