Luzzatto and colleagues1 give three recommendations for pricing orphan drugs. We will focus on the first recommendation (European price negotiation) and on the first part of the second (cost-based pricing).Negotiations at the European level are not indispensable for the public buyers to get enough market power. Even for orphan drugs, the market size of most European national insurers allows them to exert buyer market power. Most importantly, it could be inappropriate to get a single European price: differential pricing applied in the EU could increase access in all countries and provide stronger incentives for research and development.2Proposing that pricing should be based on the cost of research and development, production, and profit, could be misleading for research and development incentives and is in contrast with aligning price with the value of the drug for patient life and quality of life. The regulation of public monopolies has long shown that a cost plus reimbursement system rewards and incentivises inefficient investments; price regulation exclusively based on research and development costs (global and joint) could result in an incentive to overinvest on research and development (Averch Johnson effect).3, 4Moreover, under maximum cost per quality-adjusted life-year thresholds, prices should be the result of decentralised negotiation and market power of industry and buyer, and depend on two references: research and development and production costs, and society’s maximum willingness to pay.5The price paid for any drug is a signal to the market regarding research and development of new drugs. This signal is crucial, particularly when it comes to drugs mostly authorised with considerable uncertainty regarding their efficacy and safety.We declare no competing interests.
