DCV, SOF, and RBV combination effective/tolerated in HCV with advanced cirrhosis, post-transplant recurrence

April 25, 2015, Vienna , Austria: Phase 3 results presented today at The International Liver Congress™ 2015 show that a combination of daclatasvir (DCV), sofosbuvir (SOF) and ribavirin (RBV) for 12 weeks was effective and well tolerated amongst patients with hepatitis C virus (HCV) infection with advanced cirrhosis and post-transplant recurrence. Sustained virologic response rates at 12 weeks (SVR12) were >90% in patients with Child-Pugh class A or B cirrhosis but lower in Child-Pugh class C. SVR12 was achieved by 94% of liver transplant recipients with HCV recurrence.

ALLY-1 is an open-label study, including treatment-naive or -experienced adults with HCV infection of any genotype.

The most common adverse events (AEs) were headache, fatigue, anaemia, diarrhoea and nausea. There were no treatment-related serious AEs. One post-transplant patient discontinued all therapy after 31 days due to headache but achieved SVR12.

Introduction: The pangenotypic combination of daclatasvir (DCV) and sofosbuvir (SOF) achieves high rates of SVR in patients with chronic HCV infection. DCV+SOF has favorable safety and drug interaction profiles and a high resistance barrier. These attributes support the ALLY-1 study of DCV+SOF with ribavirin (RBV) in patients with advanced cirrhosis or post-liver transplant HCV recurrence, who have a high unmet therapeutic need.

Material and Methods: This open-label study enrolled treatment-naive or experienced adults with HCV infection of any genotype (GT) in 2 cohorts: (1) advanced cirrhosis, (2) post-liver transplant recurrence. Patients received 12 weeks of treatment with once-daily DCV 60mg + once-daily SOF 400mg and RBV (initially 600mg/d, adjusted for hemoglobin and creatinine clearance). In the cirrhosis cohort, patients transplanted during treatment could receive 12 weeks of extended treatment immediately posttransplant, regardless of treatment duration before transplant. The primary endpoint was HCV RNA 90% in patients with Child-Pugh class A or B cirrhosis but lower in Child-Pugh class C. SVR12 was achieved by 94% of liver transplant recipients with HCV.
