Condition(s) targeted: Hepatitis C, Chronic; Liver Cirrhosis

Intervention: Peginterferon alfa-2b (Biological); Ribavirin (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Merck Sharp & Dohme Corp.

Summary

The objective is to evaluate the efficacy and safety of combination therapy with peginterferon alfa-2b 1. 0 µg/kg/week subcutaneous (SC) + ribavirin administered for 48 weeks in participants with chronic hepatitis C and type C compensated liver cirrhosis. Participants who are hepatitis C virus ribonucleic acid (HCV-RNA) positive after 24 weeks of treatment will be discontinued from therapy.

Exclusion Criteria:

interferon (including polyethylene glycol-modified interferon) and ribavirin

hepatic carcinoma; decompensated liver cirrhosis with any the following diseases: ascites, jaundice, variceal hemorrhage, esophageal or gastric varices requiring treatment, hepatic encephalopathy, and idiopathic bacterial peritonitis; depression or schizophrenia requiring treatment, or suicidal attempt or suicidal ideation; epileptic seizures requiring treatment; angina, cardiac failure, myocardial infarction, or life-threatening arrhythmia; autoimmune disease (Hashimoto's disease, Crohn's disease, ulcerative colitis, chronic rheumatoid arthritis, idiopathic thrombocytopenic purpura, systemic erythematosus, autoimmune hemolytic anemia, scleroderma, etc.); hepatic carcinoma

- Participants with a history of hypersensitivity to interferon preparations,

biological products such as vaccine, or nucleoside analogs, and those with specific reaction to pegylated interferon alfa-2b in the prick test conducted before the initiation of treatment

out by serum human chorionic gonadotropin (HCG) test conducted during the screening period. Male participants with partners who are pregnant.
