About rare pediatric disease designation and priority review vouchers (PRVs) 

The rare pediatric disease PRV program aims to incentivize drug development for rare pediatric diseases. 

Under this voucher program, a sponsor who receives an approval for a drug or biological product for a rare pediatric disease may qualify for a voucher that can be redeemed to receive priority review for a different product. The sponsor may also transfer or sell the voucher to another sponsor. 

FDA awards rare pediatric disease PRVs to sponsors of rare pediatric disease products that are approved and meet certain criteria. Prior to submitting a marketing application for its drug, a sponsor that plans to request a rare pediatric disease PRV may request rare pediatric disease designation.  

See FDA’s Draft Guidance on Rare Pediatric Disease Priority Review Vouchers.

2026 update: Rare Pediatric Disease PRV program sunset

As of February 3, 2026, enactment of the Consolidated Appropriations Act, 2026, the rare pediatric disease PRV program will sunset after September 30, 2029. FDA may not award any PRVs under this program after September 30, 2029.

Please note that the current sunset provisions in the law do not provide a separate date by which the drug that is the subject of the rare pediatric disease product application must be designated as a drug for a rare pediatric disease.
