The hepatitis C virus (HCV) NS5A replication complex inhibitor daclatasvir (Daklinza(®)) is indicated for use in combination with sofosbuvir, with or without ribavirin, in a pangenotypic all-oral regimen. In patients with chronic HCV genotype 1 or 3 infection without cirrhosis, a 12-week regimen of daclatasvir plus sofosbuvir achieved high sustained virological response rates 12 weeks’ post-treatment (SVR12), regardless of prior treatment experience, according to the results of the AI444040 and ALLY-3 trials. In the ALLY-3+ trial, high SVR12 rates were achieved with a 12- or 16-week regimen of daclatasvir plus sofosbuvir and ribavirin in patients with chronic HCV genotype 3 infection and advanced fibrosis or compensated cirrhosis. A daclatasvir plus sofosbuvir-based regimen demonstrated efficacy in patients with chronic HCV genotype 1, 3 or 4 infection and advanced cirrhosis or post-transplant recurrence in the ALLY-1 trial, and in patients co-infected with HCV genotype 1, 3 or 4 and HIV-1 in the ALLY-2 trial. Results of clinical trials were supported by real-world data from early-access programmes that included high numbers of patients who would have been excluded from phase 3 trials because of advanced disease and/or concomitant medical conditions. Daclatasvir plus sofosbuvir with or without ribavirin was generally well tolerated. In conclusion, an all-oral regimen comprising daclatasvir plus sofosbuvir with or without ribavirin is an important option for use in treatment-naive or treatment-experienced patients with chronic HCV genotype 1, 3 or 4 infection, including in patients with advanced liver disease, post-transplant recurrence and HIV-1 co-infection.
