This Phase 3 clinical study is designed to evaluate the safety, tolerability, and efficacy of two dose levels of Infergen (interferon alfacon-1, CIFN) plus Ribavirin administered daily for 48 weeks and no treatment in patients chronically infected with hepatitis C who are nonresponders to previous pegylated interferon alfa plus ribavirin therapy and participated during at least 24 weeks of no treatment in IRHC-001.
At the time of randomization into IRHC-001, the no treatment arm patients will be concurrently randomized in a 1:1 ration to receive Interferon Alfacon-1 (9 or 15 µg) + Ribavirin (both administered daily) or no treatment for up to 48 weeks. Patients will not be eligible for consideration to receive treatment in IRHC-002 until they have completed a minimum of 24 weeks of participation in IRHC-001.
The protocol and informed consent form that will be used must be approved by the Investigator's Institutional Review Board (IRB)/Independent Ethics Committee (IEC) before the study is initiated.

- Evaluate sustained virologic response (SVR) rate of daily Infergen at two dose levels plus ribavirin and no treatment in chronically HCV-infected patients who are nonresponders to previous pegylated interferon alfa plus ribavirin therapy. [ Time Frame: 72 weeks ]
- Evaluate safety & tolerability of therapy detailed in primary objective, and proportion of patients with (a) undetectable plasma HCV RNA levels at weeks 24 & 48 (b) abnormal baseline serum ALT levels that are normal at week 24, week 48 and weeks 48 & 72. [ Time Frame: 72 weeks ]
