Clinical Trial Summary

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.

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.

Intervention

Drug:
• PegIntron Pen
Peginterferon alfa-2b, 1.5 microgram/kg each week, administered subcutaneously.
• 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.

Week-48
Primary	Number of Genotype-1 Participants Who Experienced Serious Adverse Events (SAE) at Week-24 Follow-up	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.	Week-24 follow-up
Primary	Number of Non-genotype-1 Participants Who Experienced Serious Adverse Events (SAE) at Week-24 of Study Treatment	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.	Week-24
Primary	Number of Non-genotype 1 Participants Who Experienced Serious Adverse Events (SAE) on Week-24 Follow-up	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.	Week-24 follow-up
Secondary	Number of Non-genotype-1 Participants Who Have Achieved Sustained Virologic Response (SVR) at Week-24 of Study Treatment	Sustained virologic response (SVR) is the absence of detectable HCV RNA in serum after end of treatment.	Week-24
Secondary	Number of Non-genotype-1 Participants Who Have Achieved Sustained Virologic Response (SVR) at Week-24 Follow-up		Week-24 follow-up
