significant changes in CD4+ cell count
(n = 207)

Results
Pts well matched at baseline: population primarily white (93% to 100%); of pts with GT1 HCV
infection, 76% to 84% had GT1a HCV; IL28B non-CC varied between arms (21% to 50%)
All pts who failed treatment relapsed; among GT1 HCV relapses, 30% developed NS5A RAVs at
failure (most in 4-wk treatment group)
Higher baseline HCV RNA (> 2 million IU/mL) and presence of cirrhosis resulted in lower SVR12
rates for pts with GT3 HCV

ALLY-1: SOF + DCV + RBV in Cirrhotic or
Posttransplant HCV-Infected Pts
Multicenter, open-label phase III trial
Enrolled advanced cirrhosis (n = 60) or post–liver transplant (n = 53) pts
– 95% and 96% of pts were white, 40% and 42% were treatment naive, 75% and
77% were infected with GT1 HCV
Treatment
– All pts: 12 wks of daclatasvir 60 mg QD + sofosbuvir 400 mg QD + RBV
– Initial RBV dose 600 mg/day, adjusted to 1000 mg/day based on hemoglobin levels and
creatinine clearance
– Pts with advanced cirrhosis who interrupted treatment due to liver transplantation
could receive 12 additional wks of therapy immediately after transplantation
– Individuals relapsing following 12 wks of daclatasvir + sofosbuvir + RBV offered
re-treatment with the same regimen for 24 wks

ALLY-1: Key Results
In subgroup analysis of pts in the advanced cirrhosis group, those who were
Child-Pugh class C (n = 16) or had albumin < 2.8 g/dL (n = 18) had SVR12 rates of 56%
10/10 pts who relapsed in the advanced cirrhosis group had NS5A RAVs at virologic
failure; 4 of 10 pts had NS5A RAVs at baseline
3/3 pts who relapsed in the posttransplantation group had NS5A RAVs at virologic
failure; none had NS5A RAVs at baseline

arms)
Almost all pts received ART (atazanavir/ritonavir, darunavir/ritonavir, lopinavir/ritonavir, efavirenz,
nevirapine, rilpivirine, raltegravir, dolutegravir, or NRTIs only)

ALLY-2: Key Results
No significant differences in SVR12 rates by HCV genotype, HCV disease characteristics, CD4+ cell
count, or ART use in either 8-wk or 12-wk arms
Ongoing control of HIV disease maintained without need for ART modification
28 of 32 pts with NS5A RAVs achieved SVR12
– Among 4 pts with NS5A RAVS who did not achieve SVR12, 3 were in 8-wk arm
– Emergent NS5A Q30 RAVs detected in 3 of 13 pts with virologic failure
