Safety,Tolerability and Pharmacokinetics of Multiple Ascending Doses of VCH 916 in Subjects With Chronic Hep C Infection

Phase 1
Completed
Conditions
HCV Infection
Interventions
Drug: Placebo
Registration Number
NCT00623649
Lead Sponsor
Vertex Pharmaceuticals Incorporated
Brief Summary

The purpose of this study is to determine whether a 3-day course of therapy with orally administered VCH-916 given at different dosages can effectively reduce the amount of circulating virus (i.e., viral load) in patients with early-stage chronic hepatitis C-infection. This study will also evaluate the safety and tolerability of treatment with VCH-916. Blood samples will also be taken to measure the levels of VCH-916 present in plasma at various time points during the treatment period.
