Brief Summary
The purpose of this 12-week study was to assess in subjects with chronic hepatitis C (treatment-naïve, genotype 1) receiving weight-based doses of ribavirin the early virologic response to the 480 ug dose level of Locteron™, dosed every 2 weeks, in comparison with 1.5 ug/kg PEG-Intron™ dosed weekly.
