- 98 percent SVR12 achieved in additional analysis of patients without cirrhosis receiving double-blind placebo for 12 weeks, followed by open-label therapy with AbbVie's investigational treatment(1)

NORTH CHICAGO, Illinois, May 27, 2015 /PRNewswire/ -- AbbVie (NYSE: ABBV) presented new results from the Phase 3 GIFT-I study of its investigational, all-oral, interferon (IFN)- and ribavirin (RBV)-free, two direct-acting antiviral treatment with ombitasvir/paritaprevir/ritonavir at the Annual Meeting of the Japan Society of Hepatology in Kumamoto, Japan.¹ GIFT-I evaluated genotype 1b (GT1b) chronic hepatitis C virus (HCV) infected Japanese patients, with and without cirrhosis, who were either treatment-naïve or IFN (with or without RBV) treatment-experienced.¹ The primary endpoint was achieved, demonstrating 95 percent (n=106/112) SVR₁₂ in a sub-group of treatment-naïve, non-cirrhotic, adult GT1b HCV infected Japanese patients who were eligible for therapy with IFN and had a high viral load.¹ In study results related to the secondary endpoint, GT1b HCV patients with compensated cirrhosis achieved 91 percent (n=38/42) SVR₁₂.¹

In an additional intent-to-treat (ITT) analysis, SVR₁₂ was achieved in 98 percent (n=104/106) of the GT1b HCV infected patients without cirrhosis (Arm B) who were randomized to initially receive double-blind placebo for 12 weeks, followed by open-label treatment with ombitasvir/paritaprevir/ritonavir.¹ The ITT population included every patient that was randomized to placebo and received at least one dose of active, open-label study drug.
