SAN RAFAEL, Calif., Nov. 24, 2015 (GLOBE NEWSWIRE) -- BioMarin Pharmaceutical Inc. (Nasdaq:BMRN) announced today that the Peripheral and Central Nervous System Drugs Advisory Committee of the U.S. Food and Drug Administration (FDA) met to discuss the data submitted to support the New Drug Application (NDA) for Kyndrisa^TM (drisapersen) for the treatment of Duchenne muscular dystrophy (Duchenne) amenable to exon 51 skipping.  The committee reviewed the Kyndrisa data package, which includes three randomized, placebo controlled trials with more than 300 patients and more than 500 patient years of exposure.  The committee discussed the overall strengths and weaknesses of the application but was not asked to vote on a recommendation for approval of Kyndrisa. 

"I'd like to thank the patients, families and physicians who participated in Kyndrisa clinical trials and in today's panel discussion," said Jean-Jacques Bienaimé, chairman and chief executive officer of BioMarin.  "We look forward to continuing our efforts to bring Kyndrisa to the Duchenne community.  After today's meeting, our next step is to continue working with the FDA as they complete their regulatory review." 

"The Committee's discussion today is part of the FDA's evaluation of Kyndrisa and the potential for a treatment option for the Duchenne community in the United States," said Debra Miller, co-founder and CEO of CureDuchenne. "We have long supported the research and development of Kyndrisa and eagerly anticipate the FDA's decision, which could make our hopes for therapy a reality."

In addition to discussing the overall strengths and weaknesses of the data supporting the efficacy of drisapersen and the acceptability of its safety profile, the FDA's advisory committee was asked to discuss the following issues and vote on the associated questions.

The Committee's feedback will be considered by the FDA in its review of the NDA for Kyndrisa. The FDA is not bound by the Committee's guidance, but takes its advice into consideration when reviewing investigational medicines.

The FDA has set a target action date of December 27, 2015, under the Prescription Drug User Fee Act (PDUFA). An application for marketing approval of Kyndrisa is also pending in the European Union.

About Duchenne Muscular Dystrophy

Changes in the dystrophin gene (mutations) that lead to the near absence of dystrophin protein result in the most severe form of dystrophin deficient muscular dystrophy, Duchenne muscular dystrophy, also known as just Duchenne. Dystrophin protein plays an important structural role in the performance of muscles. Without dystrophin, boys living with Duchenne experience progressive muscle weakness, causing serious medical complications including serious heart or respiratory-related complications, resulting in death in early adulthood.

Primarily affecting boys, Duchenne affects approximately 1 in every 3,500-5,000 male children, making it the most common fatal genetic disorder diagnosed in childhood.

There is currently no FDA approved therapy designed specifically to treat Duchenne.

About Kyndrisa and Exon Skipping

Kyndrisa is an antisense oligonucleotide that induces exon skipping to provide a molecular patch for dystrophin transcripts produced by certain mutated dystrophin genes. Exons are the parts of a gene that contain the instructions for generating a protein. In applicable cases, skipping an exon near the mutation allows for the production of a truncated but functional dystrophin protein.

Kyndrisa is the first and only investigational medicine designed specifically for the treatment of Duchenne that has received orphan drug, breakthrough drug, fast track and priority review status by the FDA.  The Kyndrisa clinical development program is the largest ever submitted to the FDA for the condition and includes more than 300 Duchenne patients and multiple randomized placebo-controlled studies.
