Hepatitis C Antiviral Long-Term Treatment Against Cirrhosis Trial

Acronym: HALT-C Trial NIDDK Contact: Edward Doo Principal Investigator(s): Not Available

Description:

This prospective, randomized, controlled clinical trial studied long-term therapy with peginterferon in patients with chronic hepatitis C. Patient enrollment began in 2000 and was completed in 2003 at 10 clinical centers, which were supported by a data coordinating center, virological testing center, and central sample repository. Patients with chronic hepatitis C and advanced fibrosis or cirrhosis on liver biopsy who failed to respond to a previous course of interferon alfa were enrolled in this study. Patients were initially treated with a 24-week course of peginterferon alfa-2a and ribavirin. Patients who remained hepatitis C virus RNA positive were then randomized to receive maintenance, low-dose peginterferon or to be followed on no treatment. Liver biopsies were done before enrollment and after 2 and 4 years of treatment or follow-up. The endpoints were development of cirrhosis, hepatic decompensation, hepatocellular carcinoma, death, or liver transplantation. 1050 patients were randomized and followed through the 4 year randomized phase of the trial and as long as 4 years off treatment.  Serum samples collected at multiple time points, DNA and liver tissue are available for scientific investigation.
