The cost-effectiveness of daclatasvir-based regimens for the treatment of hepatitis C virus genotypes 1 and 4 in the UK

Abstract

Objective: This study aimed to determine the cost-effectiveness of daclatasvir in combination with other medicinal products for the treatment of patients with hepatitis C virus genotypes 1 and 4 and advanced liver disease in the UK.

Methods: A published and validated Markov model designed to simulate the natural history of chronic hepatitis C was used to compare daclatasvir with relevant treatment options for patients with hepatitis C virus genotypes 1 and 4 and a METAVIR score of F3-F4. Patients were defined according to their treatment status; that is, naive, experienced or interferon ineligible/intolerant. Data inputs for the analysis were derived from published sources, UK-specific where possible. A lifetime horizon was used, with costs and benefits discounted at 3.5%.

Results: Daclatasvir-based regimens are estimated to be cost-effective versus no treatment and established standard-of-care regimens, including telaprevir in combination with pegylated interferon-α+ribavirin (PR), boceprevir in combination with PR and PR alone (incremental cost-effectiveness ratio range: £3715-£15,408). The cost-effectiveness of daclatasvir-based regimens versus emerging regimens (sofosbuvir or simeprevir based) is less consistent, but was dominant or cost-effective (incremental cost-effectiveness ratio range: £1394-£28,393) in all except two scenarios.

Conclusion: Daclatasvir-based regimens are expected to be highly cost-effective for the majority patients with advanced disease versus relevant comparator regimens, including newer direct-acting antiviral regimens.
