Interleukin-2 (IL-2), Pegylated Interferon (PEG-IFN Alfa-2b), and Ribavirin (RBV) Treatment in Patients With Hepatitis C and HIV Coinfection
A Pilot Study of Low Dose Interleukin-2 (IL-2) With the Addition of Pegylated Interferon (PEG-IFN Alfa-2b) and Ribavirin (RBV) for the Treatment of Hepatitis C Infection in Subjects With HIV Coinfection
This study will test the safety and effectiveness of a new treatment for hepatitis C (HCV) in patients who also have HIV.
The usual treatment for HCV in people who are not HIV-infected is interferon-alfa (IFN) with ribavirin (RBV), an approved treatment by the Food and Drug Administration (FDA). This study will use a new, longer acting form of IFN called PEG-IFN alfa-2b. PEG-IFN alfa-2b is approved by the FDA for use in treating HCV but has not yet been approved for use with RBV. This study also will use IL-2, which is a substance that the body naturally produces. People with HIV infection usually do not make enough IL-2. IL-2 is being tested in this study to see if it will "boost" the immune system's response to HCV. The FDA has approved IL-2 for the treatment of some cancers.

Detailed Description
HCV infection is an increasingly important clinical problem in patients infected with HIV. In HIV-uninfected patients with acute HCV infection, the presence of vigorous T-cell proliferative responses to HCV proteins is associated with normalization of serum transaminase levels and viral clearance. Furthermore, early results suggest IL-2 may improve transaminase levels in HCV/HIV patients. These observations provide the rationale for an immune-based therapeutic approach to HCV/HIV coinfection. This study explores the use of initial immunostimulatory therapy with IL-2 followed by the addition of antiviral therapy with PEG-IFN alfa-2b and RBV, as a possible synergistic approach to treatment.
Patients receive IL-2 for 12 weeks followed by the addition of PEG-IFN alfa-2b and RBV at the Week 12 visit. Patients remain on IL-2, PEG-IFN alfa-2b, and RBV for an additional 48 weeks. At Week 60, all study treatment is permanently discontinued and patients continue to be evaluated through Week 84. Toxicity or intolerance is evaluated. Data is collected on biochemical and virologic responses.

- Have a chronic HCV infection at least 6 months before study entry.
- Can document chronic hepatitis within 24 months before study entry.
- Agree not to become pregnant (females) or make someone pregnant (males), or donate sperm, or participate in any other fertilization procedures while on the study drugs and for 6 months afterwards. Agree to use reliable forms of birth control during the same time period.
- Have a negative pregnancy test within 30 days of study entry.
Exclusion Criteria
Patients will not be eligible for this study if they:
