7 ASTRAL-3 ASTRAL-3 study: SOF/VEL vs SOF + RBV in genotype 3  Summary –Rates of SVR 12 in every subgroup of patients with HCV genotype 3 were substantially higher among those who had received 12 weeks of SOF/VEL compared to 24 weeks of SOF + RBV, including patients with cirrhosis and previous treatment failure Overall SVR 12 of 95% with SOF/VEL for 12 weeks versus 80% with SOF + RBV for 24 weeks (p < 0.001) 91% SVR 12 rate in patients with cirrhosis Limitation : small number of black patients –However, the rate of SVR 12 was 88% among patients who had NS5A RAVs at baseline and 97% among those who did not, with the lowest rate (84%) observed among patients with the Y93H variant at baseline –SOF/VEL was well tolerated and, compared with SOF + RBV, lacked toxicities commonly associated with RBV –For patients with HCV genotype 3 infection, SOF/VEL for 12 weeks represents an improvement over standard treatment with 24 weeks of SOF + RBV, with a simple and highly effective regimen, together with shorter duration of treatment and fewer side effects, owing to the removal of RBV from the regimen Foster GR.
