AbbVie’s subsidiary to acquire United Therapeutics’ Rare Pediatric Disease Priority Review Voucher

United Therapeutics Corporation (NASDAQ: UTHR) announced today that it has entered into an agreement to sell its Rare Pediatric Disease Priority Review Voucher (PPRV) to a subsidiary of AbbVie Inc. (NYSE: ABBV). United Therapeutics received the PPRV when Unituxin™ was approved by the U.S. Food and Drug Administration (FDA) for the treatment of neuroblastoma, a rare pediatric disease.

Upon closing of the transaction, United Therapeutics will receive $350 million in cash in exchange for the PPRV. The voucher was awarded by the FDA under a provision that encourages development of new drugs and biologics for the prevention and treatment of rare pediatric diseases.

"We are very pleased to monetize our PPRV, and hope that this transaction will encourage others to join us in focusing development efforts on rare pediatric diseases," said Roger Jeffs, Ph.D., United Therapeutics' President and Co-CEO.

The transaction is subject to customary closing conditions and clearance under the Hart-Scott-Rodino Antitrust Improvements Act.
