Direct-Acting Antivirals Remain Cost-Effective Treatments for Chronic Hepatitis C in Australia Despite Changes to the Treated Population and the Availability of Retreatment: The Glecaprevir/Pibrentasvir (Maviret) Example.

Introduction: The first direct-acting antiviral (DAA) therapies for chronic hepatitis C virus (HCV) infection were reimbursed via Australia's Pharmaceutical Benefits Scheme (PBS) in March 2016. This was based on the recommendation from the Pharmaceutical Benefits Advisory Committee (PBAC) that the regimens would be acceptably cost-effective at an incremental cost-effectiveness ratio (ICER) no greater than $15,000/quality-adjusted life-year (QALY). Since the initial PBS listings for DAA therapies and subsequent listings of newer DAA treatments such as glecaprevir/pibrentasvir (Maviret), the demographics and some of the disease characteristics of currently treated patients have markedly changed.
