OBJECTIVES: Conventional cost-effectiveness analysis (CEA) for the value-based pricing of new medicines largely ignores the implications of limited market exclusivity (ie, patent-protection periods plus any exclusivity granted by regulators). This paper explores the implications of this methodological shortcoming, which produces several pricing anomalies with potentially unintended effects on research and development (R&D) incentives.
METHODS: We illustrate these implications by comparing 4 stylized examples of increasing complexity, from short-term cures for acute conditions to long-term cures for rare, health-catastrophic conditions.
RESULTS: (1) Conventional-CEA will project a different result than an adjusted CEA that considers generic or biosimilar entry; (2) free and flexible pricing of long-term treatments (eg, statins for hypercholesterolemia) or repeated-dose cures (eg, insulin for type 1 diabetes) for chronic conditions will likely result in predictable price increases at the end of the exclusivity period that may be perceived as unjustified or unsupported; and (3) one-time administration "cures" (eg, gene therapy for spinal muscular atrophy) have the potential to allocate a large share of the social surplus to the manufacturer over the product lifetime, which may or may not be dynamically efficient per se, but may also inadvertently disadvantage the development of valuable long-term treatments or repeated-dose cures for chronic conditions.
CONCLUSIONS: We highlight the need for additional research on long-term solutions to these issues that would aim to promote dynamically efficient global R&D. More work is needed on the following: (1) relationships between social surplus allocation and the amount and composition of global R&D, as we may be as likely to be encouraging excessive R&D in some areas as to be undersupplying it in others; and (2) relating the size of the surplus reward to R&D cost and, thus, the return on investment.
