Combination Drug Therapy for Patients With Hepatitis C

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Hepatitis C is a major cause of liver disease in the United States and leads to cirrhosis of the liver in approximately one-third of patients some of whom will ultimately suffer from liver failure or liver cancer. At present, the recommended therapy of hepatitis C is the combination of alpha interferon and ribavirin given for 6 to 12 months. Ribavirin is a antiviral drug that is given by mouth. Interferon is both an antiviral and an immune medication which must be given by injections (three times a week) and has many difficult side effects. The purpose of this study is to determine whether the combination of ribavirin and interferon improve the liver disease of hepatitis C and whether improvements can be maintained by continuing ribavirin therapy long-term. This study will take 100 to 120 patients suffering from hepatitis C and place them under combination drug therapy with alpha interferon and ribavirin. The course of drug therapy is scheduled to last 6 to 12 months. Patients will be selected after appropriate screening for hepatitis C virus and elevated liver enzymes are conducted and liver biopsy shows chronic hepatitis with some degree of injury and scarring. During the first 6 months of the study, subjects will be asked to return to the outpatient clinic for routine check-ups and blood tests every 2 to 4 weeks. Blood tests will include tests for hepatitis C virus. If the virus test becomes negative on treatment, the therapy will be considered successful and will be continued for a full 6 or 12 months (depending upon the strain of virus). If the virus test does not become negative during the first six months of treatment, subjects will be considered "non-responders" and will stop taking interferon but will continue on ribavirin alone or an identically appearing placebo tablet. These non-responsive subjects will continue this therapy for an additional 12 months. (A year-and-a-half total). Upon completion of the drug therapies, subjects will be requested to submit blood samples and undergo a liver biopsy to determine if the therapy was successful. Test results that reveal a loss of hepatitis C antibodies or normal levels of liver enzymes will be deemed successful. Patients that have successful laboratory test results will be considered for continuation of ribavirin therapy. Patients that received placebo for a year will be eligible to receive ribavirin long-term at the end of the study.
