SVR, sustained virologic response; TN, Treatment‐naïve; TE, Treatment‐experienced to an IFN‐containing regimen with or without RBV; VF, virologic failure.
Number of patients who experienced virologic failure. Excludes patients who did not achieve SVR due to non‐virologic reasons such as premature study drug discontinuation or missing SVR12 or SVR24 data.
Patients in study M12‐536 received OBV/PTV/r for 12 weeks, and all patients were treatment‐experienced to pegIFN/RBV and were non‐cirrhotic.
GIFT‐II treatment regimen included co‐formulated ombitasvir/paritaprevir/r (25/150/100 mg QD) + RBV for 12 or 16 weeks. Patients were treatment naïve or treatment‐experienced to an IFN containing regimen (IFN alpha, beta, or pegIFN) with or without RBV.
One GT2b‐infected treatment‐naïve patient achieved SVR12 but relapsed at PTW24.
