Clinical Trial Summary

Objectives:

Primary To compare the sustained virologic response (SVR) of PEGIntron plus ribavirin among patients receiving 48 weeks versus 72 weeks of therapy (defined as undetectable HCV RNA level 24 weeks after discontinuing therapy).

Secondary

- To evaluate the safety and tolerability PEG Intron in combination with ribavirin for treatment of Chronic Hepatitis C (CHC) infection in patients co-infected with Human Immunodeficiency Virus (HIV).

- To determine the early virologic response of patients receiving PEGIntron plus ribavirin at Treatment Week 24

Study Design:

All qualifying patients will enter the treatment phase and be dosed as follows:

Peginterferon a-2b 1.5mg/kg 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 and < 105 kg

- 1400 mg (600 mg a.m. and 800 mg p.m.) if body weight > 105 kg

At Treatment Week 24, all participants with detectable HCV-RNA will be discontinued from treatment and followed for a Post Treatment period of 24 weeks. Participants with undetectable HCV-RNA values at Treatment Week 24 will be randomized to either:

- Group A: an additional 24 weeks of previously assigned Peginterferon a-2b + Ribavirin therapy, for a total of 48 weeks of treatment.

- Group B: an additional 48 weeks of previously assigned Peginterferon a-2b + Ribavirin therapy, for a total of 72 weeks of treatment.

Study Population:

300 HIV infected adults with chronic hepatitis C infection who have not been treated previously with interferon therapy.

Dosage and Administration:

Peginterferon a-2b 1.5mg/kg 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 and < 105 kg

- 1400 mg (600 mg a.m. and 800 mg p.m.) if body weight > 105 kg

Efficacy Evaluations:

Laboratory analysis, liver biopsies, quality of life assessments, and changes in Peginterferona-2b 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
