Randomized, Multi-Center, Phase IV, Comparative Study to Assess the Efficacy and Safety of Combined Peg-Interferon Alpha-2a (40 kD) With Ribavirin Combined Therapy for 48 or 72 Weeks of Treatment and 24 Weeks of Follow-Up in Patients With Chronic Hepatitis C, Genotype 1, Co-Infected With Human Immunodeficiency Virus

This randomized, multi-center, Phase IV, comparative study will assess the efficacy and safety of combined peg-interferon alpha-2a (Peg-IFN-Alpha-2A) and ribavirin therapy for 48 or 72 weeks of treatment and 24 weeks of follow-up in participants with Genotype 1 chronic hepatitis C (CHC), co-infected with human immunodeficiency virus type 1 (HIV-1).
