An Open-label Randomized Multicenter Phase III Clinical Study Comparing Safety and Efficacy of Algeron (Cepeginterferon Alfa-2b) and and PegIntron (Peginterferon Alfa-2b) in Combination With Ribavirin as Combined Treatment of Chronic Hepatitis C in Human Immunodeficiency Virus-1 Infected Patients

NCT ID: NCT02103439

Last Updated: 2018-08-09

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE3
• Total Enrollment: 140 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2013-06-06

Brief Summary

The purpose of the study is to demonstrate the noninferiority of Algeron in combination with ribavirin compared to PegIntron in combination with ribavirin in treatment of chronic hepatitis C in Human Immunodeficiency Virus-1 infected patients

Detailed Description

The course of treatment in both groups shall be 12 weeks, and efficacy analysis, i.e. rate of rapid (after the 4th week) and early (after the 12th week) virologic response will be based on polymerase chain reaction data. For patients with treatment failure after the 12th week the antiviral therapy shall be discontinued. All patients who require further anti-viral treatment will receive a combination treatment with Algeron / PegIntron and ribavirin for another 36 weeks. Sustained virologic response will be assessed 24 weeks after last dose of study treatment.
