NOVATO, Calif., Dec. 18, 2017 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (NASDAQ:RARE), a biopharmaceutical company
focused on the development of novel products for rare and ultra-rare diseases, today announced that it has entered into a
definitive agreement to sell its Rare Pediatric Disease Priority Review Voucher (PRV) to Novartis for $130,000,000.
Ultragenyx was awarded the voucher under a U.S. Food and Drug Administration (FDA) program intended to encourage the development of
treatments for rare pediatric diseases. The Company received the PRV in November when MEPSEVII™ (vestronidase alfa) was approved by
the U.S. FDA for the treatment of children and adults with Mucopolysaccharidosis VII (MPS VII, Sly syndrome).
“The sale of the PRV provides us with an important source of non-dilutive capital to help advance our pipeline of rare and
ultra-rare therapies, and accelerates the availability of these potential therapies to patients,” said Emil D. Kakkis, M.D., Ph.D.,
Chief Executive Officer and President of Ultragenyx.
Under the agreement, Ultragenyx will receive a lump sum payment of $130 million upon the closing of the transaction, which is
subject to customary closing conditions including antitrust review.
About the Rare Pediatric Disease Priority Review Voucher Program
This U.S. FDA program is intended to encourage development of new drug and biological products for prevention and treatment of
certain rare pediatric diseases. Under this program, a sponsor who receives an approval for a drug or biologic for a "rare
pediatric disease" may qualify for a PRV that can be redeemed to receive a priority review of a subsequent marketing application
for a different product. The sponsor receives the PRV upon approval of the rare pediatric disease product application and it can be
sold or transferred.
