Official title Multicenter Open-label Randomized, Comparative Clinical Study to Evaluate Efficacy and Safety of Algeron (Cepeginterferon Alfa-2b, CJSC "BIOCAD", Russia) With Ribavirin Compared to PegIntron (Peginterferon Alfa-2b, Schering-Plough Labo N.V., Belgium) With Ribavirin in Treatment of Chronic Hepatitis C in Human Immunodeficiency Virus-1 Infected Patients
Principal investigator Gregory Moshkovich, M.D.
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.
