History of Changes
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.

|Official Title:||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|
Further study details as provided by National Institute of Allergy and Infectious Diseases (NIAID):
|Study Completion Date:||March 2005|
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.
|Ages Eligible for Study:||18 Years to 65 Years|

- Have a detectable HCV viral load within 30 days before study entry.
- 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.
- Have IgM antibody to hepatitis A within 30 days before study entry.
- Are coinfected with HBV within 30 days before study entry.
- Have had a liver biopsy showing liver disease (unless due to HCV) within 2 years before study entry.
- Have disease associated with the immune system such as Crohn's disease, ulcerative colitis, active rheumatoid arthritis, lupus, idiopathic thrombocytopenic purpura, autoimmune hemolytic anemia, cryoglobulinemia with clinical manifestations including leukocytoclastic vasculitis, scleroderma, and severe psoriasis.
- Have severe cirrhosis of the liver.
- Have significant heart problems.
- Have a thyroid problem which has not been treated.
- Have a history of severe mental problems.
- Have taken the following within 6 weeks before study entry: rifampin, rifabutin, pyrazinamide, isoniazid, G-CSF (filgrastim), GM-CSF (sargramostim), or ganciclovir.
- Have taken any of the following within 6 months before study entry: interleukins, interferons, therapeutic HIV vaccine, thalidomide, pentoxifylline, dinitrochlorobenzene (DNCB), thymosin alpha, thymopentin inosiplex, polyribonucleoside, ditiocarb sodium, hydroxyurea, systemic corticosteroids, azathioprine, 6-mercaptopurine, cyclosporin A, or any investigational drug.
- Have taken interferon or ribavirin any time before study entry.
- Have a disease affecting the red blood cells.
- Have retinopathy (disease of the eye).
- Have a chronic liver disease other than HCV.
- Are pregnant or breast-feeding.
- Are allergic to IL-2, PEG-IFN alfa-2b, or RBV or other components of the study products.
- Are presently using illegal drugs.
- Have had more than 1 alcoholic drink per day during the previous 30 days before study entry, or more than 4 drinks per day during the previous 6 months.
- Have been treated for a serious infection or other serious medical illness within 14 days before study entry.
- Have uncontrolled seizures.
- Have serious breathing and lung problems.
- Have had a major organ transplantation.
- Have history of a severe medical problem that would make the patient unsuitable for the study.
- Have had treatment for cancer or treatment affecting the immune system within 24 weeks
