Competition From Biosimilars Drives Price Reductions For Biologics In The French Single-Payer Health System

France has a single-payer health insurance system that has the authority to impose pharmaceutical price reductions but relies on decentralized market negotiations between hospitals and manufacturers to establish prices for injected and infused biologics. Hospitals rely on biosimilars-less expensive but therapeutically equivalent variants of biologic medications-to stimulate competition. Price reductions negotiated by hospitals subsequently are adopted by the health insurance system, driving hospitals to negotiate a new round of discounts. This article measures 2004-20 trends in prices, price reductions, utilization, and market shares for three prominent biologics-Remicade, Enbrel, and Humira-and their eleven competing biosimilars. Biosimilar launches are associated with a sequence of price reductions for the reference biologic, for other biologics that treat similar conditions, and for all related biosimilars. The French experience provides lessons for the US in its efforts to use competition from biosimilars to drive price reductions and savings from biologics.
