ASTRAL-4 Study: SOF/VEL in patients with decompensated liver disease • Summary • Treatment with SOF/VEL for 12 or 24 weeks or SOF/VEL + RBV for 12 weeks resulted in high SVR12 rates in HCV patients with decompensated cirrhosis caused by HCV of all genotypes • SOF/VEL + RBV resulted in the highest overall SVR12 rates, with the lowest rates of virologic failure in HCV genotype 3 patients • Treatment was associated with improved MELD and CPT scores largely due to decreased bilirubin and improvement in synthetic function (albumin) • SOF/VEL for 12 or 24 weeks or SOF/VEL + RBV for 12 weeks was safe and well tolerated, with adverse events consistent with clinical sequelae of advanced liver disease and RBV toxicity • Limitations • Study not powered to detect significant differences among the 3 treatment groups • Only patients with moderate hepatic decompensation were enrolled • The numbers of patients with HCV genotype 2, 4, or 6 were small • Limited number of black patients Curry MP.
