Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

SCV-07 (γ-D-glutamyl-L-tryptophan) is a new immunomodulatory compound that has been developed and patented both for composition and immunomodulatory use and is a synthetic dipeptide. The efficacy of SCV 07 in treating chronic hepatitis C virus (HCV) infection is expected to arise from the drug's ability to stimulate the T-helper 1 (Th1) type immune response and to block signal transducers and activator of transcription 3 (STAT3) mediated signaling. The purpose of this study is to determine if SCV-07 alone and/or SCV-07 in combination with ribavirin is safe and potentially effective for the treatment of genotype 1 compensated chronic hepatitis C in subjects who have relapsed after a response to a previous treatment course of at least 44 weeks with pegylated interferon and ribavirin. All subjects will receive 4 weeks of SCV-07 (Lead-in Phase), followed by 4 weeks of treatment with SCV-07 in combination with ribavirin (Combination Treatment).

Cohort 1: SCV-07 0.1 mg/kg. Cohort 2: 1.0 mg/kg per day administered SC

Group Type EXPERIMENTAL

SCV-07

Intervention Type DRUG

SCV-07 dosage will remain the same throughout the study for each cohort. Monotherapy Lead-in Phase Treatment (SCV-07) for 4 weeks. Combination Treatment (SCV-07 and ribavirin) for 4 weeks, following "Lead-in Phase". Re-treatment with peg INF and RBV will be offered in the "Follow-up" to patients who in the opinion of the investigator may benefit from treatment. All patients will have a total of 3 follow-up visits for safety assessments. Women of childbearing potential will be followed up monthly for approximately up to 6 months after the "end of treatment" visit. If pregnancy occurs within the follow-up period, it needs to be followed through 8 weeks after the end of pregnancy.
