All-oral, IFN-free, 12-week regimens of ABT-450/r + ombitasvir resulted in:

– High SVR12 rates in treatment-naïve HCV GT4-infected patients• 90.9% with ABT-450/r + ombitasvir• 100% with ABT-450/r + ombitasvir + RBV

– An SVR4 rate of 100% in treatment-experienced patients receiving ABT-450/r + ombitasvir + RBV

2-week regimens of ABT-450/r + ombitasvir +/-RBV were generally well-tolerated, with no study
