Summary –OBV/PTV/r FDC + DSV, without the use of RBV, given for 12 weeks achieved SVR 12 of 100% in genotype 1b infected patients with compensated cirrhosis, including treatment-experienced patients –Treatment was very well tolerated, with a low rate of serious adverse events, no premature discontinuations, and infrequent laboratory abnormalities that were not clinically relevant TURQUOISE-III TURQUOISE-III Study: ombitasvir/paritaprevir/ritonavir + dasabuvir for genotype 1b with cirrhosis Feld JJ.
