Brief Summary

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

The purpose of this study is to assess the safety, tolerability and effectiveness of ANA598 when administered with pegylated interferon and ribavirin (Standard of Care \[SOC\]) compared to placebo + SOC.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The safety, tolerability and antiviral activity of ANA598, administered orally at 200 mg BID or 400 mg BID for 12 weeks in combination with pegylated interferon and ribavirin (SOC) will be compared to placebo + SOC. Treatment-naïve patients with genotype 1 infection will be eligible for enrollment. Patients randomized to ANA598 will receive a loading dose of 800 mg q 12 hours administered on the first day of dosing. Patients with undetectable HCV RNA at week 4 and week 12 will be randomized to receive either an additional 12 or 36 weeks of SOC alone.

Ninety patients will be randomized into 2 cohorts. The forty-five patients in each cohort will be randomized as 30 active: 15 placebo.
