FDA Receives Paragraph IV Notice Letter for KUVAN(R) (sapropterin dihydrochloride) Tablets

SAN RAFAEL, Calif., Sept. 24, 2014 (GLOBE NEWSWIRE) -- BioMarin Pharmaceutical Inc. (Nasdaq:BMRN) today announced that a Paragraph IV Certification Notice Letter was submitted to the US Food and Drug Administration (FDA) in connection with an Abbreviated New Drug Application (ANDA) to the FDA for approval to market a generic version of KUVAN® (sapropterin dihydrochloride) Tablets, although it has not yet received notice of the certification.

BioMarin has 8 patents listed in the FDA Orange Book with expiration dates between 2024 and 2026. BioMarin will evaluate the Paragraph IV certification when it receives the Notice Letter and intends to vigorously enforce its intellectual property rights. By statute, if BioMarin initiates a patent infringement lawsuit against the party submitting the letter within 45 days of receiving the notice letter, then the FDA would be automatically precluded from approving the ANDA for 30 months, or until a district court decision finding the patents invalid or not infringed, whichever occurs earlier. Once the lawsuit is filed, the 30 month stay period will begin as of the date BioMarin was notified of the filing.

"We believe that our patents related to KUVAN are valid and enforceable and intend to assert our rights vigorously." said Jean-Jacques Bienaimé, BioMarin's CEO. "We have thoroughly prepared for this possibility and intend to file suit within the necessary time frame."
