Clinical Benefit and Revenues of Drugs Affected by Rare Pediatric Disease Priority Review Vouchers, 2017-2023.

ABSTRACT

OBJECTIVE: To determine the clinical benefit of drugs that earned or redeemed rare pediatric disease priority review vouchers (PRVs) from 2017 through 2023, and the revenues generated by such drugs. STUDY DESIGN: In this cohort study, Federal Register documents, publicly available health technology agency (HTA) assessments, and financial filings were used to identify drugs that were issued or redeemed using a rare pediatric disease PRV from 2017 through 2023, and to assess their added therapeutic benefit and drug-specific global revenues. RESULTS: Among the 36 drugs whose approval resulted in issuance of a rare pediatric PRV, therapeutic benefit ratings were available for 17 (47%), with 9 (53%) rated as high by at least 1 organization. Mean annual global revenues were $363 million (year 1), $621 million (year 2), and $850 million (year 3). The median annual list price for drugs issued a voucher was $788,705. Vouchers were then redeemed for 15 different drugs; out of 13 drugs with therapeutic benefit ratings, 4 (31%) were high value. CONCLUSIONS: Drugs that treat rare pediatric diseases generate similar revenues compared with other brand drugs, and drugs with high therapeutic benefit tend to generate more revenue than those with low therapeutic benefit. Drugs that earned the rare pediatric disease PRV for their manufacturer generate significant revenues and the voucher may not be necessary to incentivize drug development in the rare pediatric disease space.
