Brief Summary:
This trial will test the hypothesis that CF102 can safely and effectively suppress viral load in patients with chronic hepatitis C and high circulating levels of virus. The trial will monitor the safety of twice-daily oral dosing with CF102 over a 16-week period; will measure changes in viral load during therapy; and will measure blood concentrations of CF102 at various time points during dosing.

Condition or disease Intervention/treatment Phase
Chronic Hepatitis C Drug: CF 102 Drug: Placebo Phase 1 Phase 2

Detailed Description:

This is a Phase 1/2, randomized, double-blind, placebo-controlled, dose-escalation study of subjects with chronic hepatitis C genotype 1. Eligible subjects will be assigned in a 3:1 ratio (8 subjects in each cohort) to receive qd or bid treatment for 15 days with oral CF-102 or with placebo. Dose escalation will occur in 2 sequential cohorts.

The decision to continue dosing within a cohort (eg, Subcohort 1a to Subcohort 1b), or to escalate to a new dose level Cohort (eg, Subcohort 1b to Subcohort 2a) will be determined by a blinded independent review of safety data. This review will be conducted by a qualified Safety Review Committee comprising the medical monitor, the consulting toxicologist, and an independent expert clinician.

For the first 2 cohorts, subjects will return to the study center for follow-up assessments on Days 8, 15, and 22. Subjects dosed qd will receive a total of 15 doses of CF-102. Subjects dosed bid will receive a total of 29 doses. The 30th dose has been deleted to accommodate PK sampling on the morning of Day 16, 24 hours after the last dose of CF-102.

For the 3rd cohorts, subjects will return to the study center for follow-up assessments on weeks 2, 4, 8, 12, 16 and 18.
