NEW YORK (Dec. 27, 2007) — As reported recently in the journal Hepatology, WIN-R, a multicenter study of over 5,000 patients with hepatitis C virus (HCV) showed treatment with weight-based REBETOL® (ribavirin, USP) (RBV) in combination with pegylated interferon (PEG-IFN) alfa-2b achieved significantly higher rates of sustained virologic response (SVR) and lower relapse rates compared to combination therapy using a flat dose of RBV 800 mg/day. Superior response was found particularly in patients with the most difficult-to-treat form of the disease, genotype 1 HCV. Efficacy was consistent across all weight groups.
