Injection drug use accounts for transmission of a high proportion of Hepatitis C Virus (HCV) infections. The purpose of this trial is to investigate the effectiveness of pegylated interferon in treating injection drug users (IDUs) with acute HCV.

Enrollment: 21
Study Start Date: April 2003
Study Completion Date: June 2007
Primary Completion Date: December 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: PegInterferon
Arm 1: 24 weeks of weekly injections of peginterferon Arm 2: control (no treatment)
Drug: Pegylated Interferon
Weekly injections of pegIntereferon

Detailed Description:

IDUs are at high risk for developing HCV. Pegylated interferon is a man-made form of interferon, a chemical naturally produced by the body that works to fight viruses. Interferon helps to stop HCV from replicating, and helps the immune system to kill HCV. The purpose of this trial is to determine the effectiveness of pegylated interferon in IDUs with HCV.

This trial will last 24 weeks. Participants will be randomly assigned to one of two groups. Group 1 will receive pegylated interferon while group 2 will receive an active control. Injection with either pegylated interferon or control will occur weekly. During each injection visit, participants will be asked about adverse events, including common side effects to interferon such as injection site reactions, headache, myalgias, arthralgias, insomnia, and hair loss. At Weeks 2, 4, and then every 4 weeks thereafter, participants will complete depression self-reports. Laboratory assessments will occur at Week 2, and then on a monthly basis for the remainder of the study. Follow-up assessments will occur every 4 weeks after Week 24.
