Background: The cost of interferon-free combination therapies remains high to provide widespread access to treatment, regardless of fibrosis stage.
Aim: To estimate the cost-effectiveness of simeprevir/daclatasvir (SMV/DCV) therapy in treatment-naïve chronic hepatitis C genotype-1b patients with moderate fibrosis.
Methods: A Markov model was developed to simulate the natural history of chronic hepatitis C progression. The model estimated lifetime healthcare costs and quality-adjusted life-years (QALY) for a cohort of patients from the Spanish National Healthcare System perspective. The cost-effectiveness threshold considered was €40,000/QALY. The treatment strategies analyzed were SMV/DCV, peginterferon/ribavirin/telaprevir, and peginterferon/ribavirin/boceprevir. A sensitivity analysis was carried out.
Results: The incremental cost-effectiveness ratios of the SMV/DCV strategy were €23,774/QALY and €28,524/QALY compared with that of telaprevir or boceprevir triple therapy, respectively, for genotype-1b patients with moderate fibrosis.
Conclusions: SMV/DCV combination compared with the standard of care previous to the arrival of second-generation direct-acting antivirals fell below generally accepted willingness-to-pay threshold. Results obtained should be supported by ongoing clinical trials.
