Summary

Objectives: Primary To evaluate the safety, tolerability, and efficacy of Peginterferon a-2a plus Ribavirin for the treatment of chronic hepatitis C (CHC) infection in persons co-infected with human immunodeficiency virus (HIV) who have failed to achieve a sustained virologic response following previous interferon therapy. Secondary - To evaluate the virological response to Peginterferon a-2a plus Ribavirin at weeks 12 and 24 as compared to baseline values. - To evaluate the sustained virological response Peginterferon a-2a plus Ribavirin at post-treatment weeks 4, 12, and 24 as compared to baseline. - To evaluate the histological effects of long-term Peginterferon a-2a therapy through comparison of liver biopsy results following 96 weeks of Peginterferon a-2a therapy to baseline values. - To evaluate the safety and tolerability of long-term Peginterferon a-2a therapy in patients who have previously failed to achieve a sustained virologic response following interferon therapy. - To investigate the effects of long-term Peginterferon a-2a therapy on clinical outcomes of HIV disease. Study Design: All qualifying patients will enter the treatment phase and be dosed as follows: Peginterferon a-2a 180mg by subcutaneous route once weekly plus Ribavirin: - 800 mg (400 mg bid) if body weight < 65 kg - 1000 mg (400 mg a.m. and 600 mg p.m.) if body weight > 65 kg and < 85 kg - 1200 mg (600 mg bid) if body weight > 85 kg Patients with undetectable levels of HCV-RNA at Treatment Week 24 will continue on previously assigned Peginterferon a-2a plus Ribavirin combo-therapy for an additional 24 weeks. Patients with detectable levels of HCV-RNA will be randomized to Peginterferon a-2a mono-therapy or no treatment for 72 weeks. - Group A: Peginterferon a-2a 90mg mono-therapy for 72 weeks. - Group B: No CHC therapy for 72 weeks All patients entering the study are required to have a baseline liver biopsy (within 18 months of study entry). Patients entering the 72-week randomized arm of the trial will have a post-study liver biopsy upon completion of the trial. Study Population: 100 HIV infected adults with chronic hepatitis C infection who have failed to achieve a sustained virologic response following previous interferon therapy. Dosage and Administration: Combo-therapy: Peginterferon a-2a 180mg by subcutaneous route once weekly plus Ribavirin: - 800 mg (400 mg bid) if body weight < 65 kg - 1000 mg (400 mg a.m. and 600 mg p.m.) if body weight > 65 kg and < 85 kg - 1200 mg (600 mg bid) if body weight > 85 kg Mono-therapy: Peginterferon a-2a 90mg in 1mL solution administered subcutaneously once weekly. Efficacy Evaluations: Laboratory analysis, liver biopsies, quality of life assessments, and changes in Peginterferona-2a and Ribavirin dosages will be obtained. Safety Evaluations: - Assessment of laboratory evaluations - vital signs - incidence and severity of adverse experiences - dose adjustments - premature withdrawal for safety reasons - progression of disease as measured by HCV viral load - AIDS defining events
