Abstract

An all-oral, pegylated interferon (pegIFN)-free and ribavirin (RBV)-free single-tablet of ledipasvir (LDV) and sofosbuvir (SOF) is now approved for the treatment of patients infected with hepatitis C virus (HCV) genotype 1.To estimate the health economic outcomes for LDV/SOF compared with current treatments in US patients infected with HCV genotype 1.A hybrid decision-tree and Markov state-transition model was developed. For a cohort of 10 000 patients, the model captured outcomes for several pairings of LDV/SOF with comparators, including long-term health outcomes, number need to treat, life-years gained, quality-adjusted life-years (QALYS) gained, incremental cost-effectiveness ratios and costs per sustained virologic response (SVR). Patients with different levels of treatment experience and different cirrhosis stages were included.LDV/SOF decreased the number of advanced liver disease cases by 0-93% compared with current regimens or no treatment in treatment-naïve patients. In treatment-experienced [pegIFN plus ribavirin (PR) or protease inhibitor (PI) + PR] patients, treatment with LDV/SOF decreased the incidence of advanced liver disease complications in most of the cases analysed, except SOF + SMV. For all patient sub-cohorts, LDV/SOF was associated with the lowest 1-year costs per SVR and, with regard to lifetime incremental costs per QALY gained, was either dominant or the most cost-effective treatment. Overall, treatment initiation at earlier stages of liver fibrosis resulted in improved health economic outcomes.LDV/SOF is associated with more favourable short- and long-term health economic outcomes compared with current therapies for patients across all levels of treatment experience and cirrhosis stages.
