Background and Aims: Daclatasvir plus asunaprevir dual oral therapy (DCV+ASV) has demonstrated potent antiviral activity in HCV genotype 1b infection. This phase 3 study (AI447028) evaluated DCV+ASV in a broad range of patients, including those with cirrhosis.
Results: Overall, patients were 49% male, 68% white, and 71% IL28B non-CC; 30% had cirrhosis. SVR12 rates among DCV+ASV-treated patients were 90%, 82%, and 82% in the naive, null/partial, and ineligible/intolerant groups (Table 1). No differences in SVR12 rates were observed based on age, gender, race, or IL28B genotype; SVR12 rates were similar across all groups in non-cirrhotic (85%; n=437) and cirrhotic (84%; n=206) patients. Serious AEs occurred in 6% and AEs leading to discontinuation (reversible elevated ALT/AST most common) in 2%, with no deaths. Grade 3/4 laboratory abnormalities were uncommon, including low incidences of ALT elevations (first 12 weeks) with DCV+ASV or placebo in naive patients (2% for both).
Conclusions: DCV+ASV provided high SVR12 rates of 90% (treatment-naïve) and >80% (null/partial and ineligible/intolerant), including in cirrhotics, and was generally well tolerated in patients with HCV genotype 1b infections.
