This study will evaluate the safety and effectiveness of combination therapy with peginterferon alfa-2b and ribavirin for treating hepatitis C virus (HCV) infection in HIV-infected patients. In studies of patients with hepatitis C alone, interferon alfa-2b plus ribavirin treatment eradicated the HCV in almost half the patients. Peginterferon alfa-2b is a compound that results from attaching a polyethylene glycol molecule to interferon alfa-2b. This compound stays in the blood longer than unmodified interferon alfa-2b, causing a higher blood concentration and thus maintaining activity against the hepatitis C virus.
HIV-infected patients 21 years of age and older with chronic hepatitis C infection and a viral load greater than 2000 copies/mL may be eligible for this 2 1/2-year study. Candidates will be screened with blood and urine tests and possibly a liver biopsy, if a recent one is not available. The liver biopsy is done to determine the severity of liver disease. For this test, patients are admitted to the NIH Clinical Center for 1 to 2 days. A sedative is injected into an arm vein, the skin in the area over the biopsy site is numbed with a local anesthetic, and a needle is inserted rapidly into and out of the liver to obtain a small tissue sample. The patient remains in the hospital overnight for monitoring. A chest X-ray, electrocardiogram (EKG) and liver ultrasound are also done. Within 4 weeks of the screening tests, candidates who appear eligible for the study will have a physical examination, medical history and repeat blood tests. Women who can become pregnant will have serial pregnancy tests throughout the study.
Patients who meet the study criteria and decide to participate will begin treatment with weekly injections under the skin of peginterferon alfa-2b and take ribavirin pills twice a day by mouth. In addition, patients will continue to take all other medications prescribed by their doctor. Clinic visits will be scheduled as follows:
- Days 1, 3, 5, 7, 10 and 21 - Blood will be drawn for safety tests and to measure blood levels of HIV and HCV.
- Weeks 2, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 52, 56 and 64 - Blood and urine tests will be done to determine the side effects of treatment and its effect on the HCV infection.
- Week 48 or end of treatment - Treatment will stop after 48 weeks. At this time, or earlier for those who do not complete the 48 weeks, patients will return to the clinic for a routine test.

|Official Title:||A Non-Randomized, Open Label, Study to Assess Hepatitis C Viral Kinetics in Predicting the Clinical Response in Patients With Hepatitis C Infection Coinfected With HIV-1 Treated With Peginterferon Alpha-2b and Ribavirin|
|Study Start Date :||June 2001|
|Actual Primary Completion Date :||April 2009|
|Actual Study Completion Date :||April 2009|
Weekly Injection of peginterferon alfa-2b and weight based ribavirin (1-1.2g/day) for 48 weeks
Drug: Peginterferon alfa-2b
Weekly injections for 48 weeks of a dose of 1.5mcg/Kg per week subcutaneously
Weight based Ribavirin dosing 1-1.2grams/day in divided (twice daily) doses for a total duration of 48 weeks.
- Participants With Viral Decline at Day 3 & 28 With Predictors of Post Treatment Response [ Time Frame: Day 3 and Day 28 ]
HCV viral kinetics were used to predict rates of sustained virology response (SVR) in HIV/HCV connected subjects.
Measure was determined by analyzing the population of participants with virologic decline of more than 1.0 log at day 3 combined with viral load of less than 5.0 log IU/ml at day 28 to predict sustained virology response
