  Purpose

This is a non-interventional study designed to evaluate the efficacy and safety of combination study drugs in the treatment of participants diagnosed with Chronic Hepatitis C (CHC). CHC participants with confirmed positive hepatitis-C virus (HCV) RNA in plasma, and who have not been previously treated with the Pegylated interferon (PegIntron) Pen, were enrolled into study.

Primary Outcome Measures:
  • Number of Genotype-1 Participants Who Experienced Serious Adverse Events (SAE) at Week-48 of Study Treatment [ Time Frame: Week-48 ] [ Designated as safety issue: Yes ]
    Collection of all safety reports (serious adverse events) from genotype-1 population at week-48 of treatment, from participants on pegylated interferon (PegIntron) pen plus ribavirin.

  • Number of Genotype-1 Participants Who Experienced Serious Adverse Events (SAE) at Week-24 Follow-up [ Time Frame: Week-24 follow-up ] [ Designated as safety issue: Yes ]
    Collection of all safety reports (serious adverse events) from genotype-1 population at week-24 non-treatment follow-up, from participants on pegylated interferon (PegIntron) pen plus ribavirin.

  • Number of Non-genotype-1 Participants Who Experienced Serious Adverse Events (SAE) at Week-24 of Study Treatment [ Time Frame: Week-24 ] [ Designated as safety issue: Yes ]
    Collection of all safety reports (serious adverse events) from Non-genotype-1 population at week-24 of study treatment, from participants on pegylated interferon (PegIntron) pen plus ribavirin.

  • Number of Non-genotype 1 Participants Who Experienced Serious Adverse Events (SAE) on Week-24 Follow-up [ Time Frame: Week-24 follow-up ] [ Designated as safety issue: Yes ]
    Collection of all safety reports (serious adverse events) from Non-genotype-1 population at week-24 non-treatment follow-up, from participants on pegylated interferon (PegIntron) pen plus ribavirin.


Secondary Outcome Measures:
  • Number of Non-genotype-1 Participants Who Have Achieved Sustained Virologic Response (SVR) at Week-24 of Study Treatment [ Time Frame: Week-24 ] [ Designated as safety issue: No ]
    Sustained virologic response (SVR) is the absence of detectable HCV RNA in serum after end of treatment.

  • Number of Non-genotype-1 Participants Who Have Achieved Sustained Virologic Response (SVR) at Week-24 Follow-up [ Time Frame: Week-24 follow-up ] [ Designated as safety issue: No ]
  • Number of Genotype-1 Participants Who Have Achieved Sustained Virologic Response (SVR) at Week-48 of Study Treatment [ Time Frame: Week-48 ] [ Designated as safety issue: No ]
  • Number of Genotype-1 Participants Who Have Achieved Sustained Virologic Response (SVR) at Week-24 Follow-up [ Time Frame: Week-24 follow-up ] [ Designated as safety issue: No ]
  • Participants' Overall Rating of Satisfaction and the Use of Training Materials for the Pegintron Pen, as Provided in a Study Questionnaire [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
    Participants will complete a single questionnaire during the first follow-up visit (Week 12). The questionnaire will measure the participant's satisfaction and the use of training materials for the PegIntron Pen during the course of study therapy, as measured by the participant using a 1- 5 score system provided in the questionnaire.


Biospecimen Retention:   Samples With DNA

Efficacy measurements for sustained viral response HCV RNA were collected at week 24 of study treatment and at week 24 of follow-up in Non-genotype-1 participants. Efficacy measurements for Genotype-1 participants for sustained viral response HCV RNA were collected at week 24 and at week 48 of study treatment, and at week 24 of follow-up.

Groups/Cohorts Assigned Interventions
Genotype 1 CHC Participants Drug: PegIntron Pen
Peginterferon alfa-2b, 1.5 microgram/kg each week, administered subcutaneously.
Other Name: pegylated interferon Pen
Drug: Ribavirin
Dose is based on body weight. Each tablet of ribavirin is 200mg, and given by oral administration. Participants with body weight of <65 kg were administered 800 mg of ribavirin daily, body weight of 65 kg-85 kg received 1000 mg daily, and participants with a body weight of >85 kg received 1200 mg of ribavirin daily.

Non-genotype 1 CHC participants Drug: PegIntron Pen
Peginterferon alfa-2b, 1.5 microgram/kg each week, administered subcutaneously.
Other Name: pegylated interferon Pen
Drug: Ribavirin
Dose is based on body weight. Each tablet of ribavirin is 200mg, and given by oral administration. Participants with body weight of <65 kg were administered 800 mg of ribavirin daily, body weight of 65 kg-85 kg received 1000 mg daily, and participants with a body weight of >85 kg received 1200 mg of ribavirin daily.

Detailed Description:

Participants with positive genotype-1 HCV RNA received 48 weeks of treatment of PegIntron Pen plus ribavirin and 24 weeks of follow-up. Participants who were non-genotype-1 HCV RNA positive received 24 weeks of treatment of PegIntron Pen plus ribavirin and 24 weeks of follow-up. Participants were asked to complete a questionnaire to measure the satisfaction and the use of training materials of PegIntron pen using a 1-5 score system provided in the questionnaire. The questionnaire was completed once at first follow-up visit. Efficacy measurements for sustained viral response HCV RNA was collected at week-24 of treatment and at week-24 of follow-up in positive Non-genotype-1 HCV RNA participants. Efficacy measurements for sustained viral response HCV RNA was collected at week-24 and at week-48 of treatment, and at week-24 of follow-up, for positive Genotype-1 HCV RNA participants.
