Evaluating Safety and Efficacy In Hepatitis C Patients After PegIntron Pen Treatment (Study P04896)

May 20, 2024 updated by: Merck Sharp & Dohme LLC

Non-Interventional Study Evaluating The Safety and Efficacy In Patients Receiving New PegIntron Pen for Hepatitis C

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.

Conditions

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.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Genotype 1 CHC Participants
Peginterferon alfa-2b, 1.5 microgram/kg each week, administered subcutaneously.
Other Names:
  • pegylated interferon Pen
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.
Other Names:
  • Ribasphere, Vilona, Copegus, Rebetol, Virazole
Non-genotype 1 CHC participants
Peginterferon alfa-2b, 1.5 microgram/kg each week, administered subcutaneously.
Other Names:
  • pegylated interferon Pen
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.
