Comparison of Two Financial Incentives to Encourage the Use of Adalimumab Biosimilars: Results of a French Experiment Close to Clinicians

In 2018, the French government introduced two mutually exclusive financial incentives to increase etanercept and insulin glargine biosimilar use. The general case redirects 20% of the price difference between the reference product and its biosimilars to hospitals for every biosimilar dispensed in community pharmacies from hospital prescriptions. The experimental case redirects 30% to prescribing clinical units after hospital selection. Adalimumab was added to these incentives in 2019, after its first biosimilar was launched.
