Amicus Therapeutics Plans to Submit New Drug Application (NDA) for Migalastat for Fabry Disease Following Positive Pre-NDA Meeting With FDA

NDA Submission to Request Accelerated Approval (Subpart H) on Track for 4Q15

CRANBURY, N.J., Sept. 15, 2015 (GLOBE NEWSWIRE) -- Amicus Therapeutics (Nasdaq:FOLD), a biotechnology company at the forefront of therapies for rare and orphan diseases, today announced that a Pre-NDA meeting was held with the U.S. Food and Drug Administration (FDA) to discuss the oral small molecule pharmacological chaperone migalastat for the treatment of Fabry disease. The unique mechanism of action of migalastat represents a new personalized medicine option for Fabry patients who have amenable mutations.

Based on FDA feedback at the Pre-NDA meeting, reduction in disease substrate (kidney interstitial capillary GL-3) will serve as the primary endpoint, supported by the totality of data from completed clinical studies. Amicus remains on track to submit an NDA in the fourth quarter of 2015 under Accelerated Approval, which is only available to therapies for severe and life-threatening conditions that address significant unmet medical needs.1 Discussions with the FDA on the Phase 4 program required for a Subpart H approval have focused on a study of the effect of migalastat on gastrointestinal symptoms associated with Fabry disease. In addition to the NDA submission, Amicus intends to submit for review the protocol for the Phase 4 study confirming the positive effects of migalastat on gastrointestinal symptoms in these patients.

"Our collaborative Pre-NDA meeting represents a significant milestone for the Fabry community in the United States and is a great example of FDA and industry working together to advance innovative therapies for people living with debilitating genetic disorders," stated John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics. "The guidance provided by FDA during the Pre-NDA meeting further reinforces our confidence in the NDA package and post-marketing confirmatory study we are preparing for submission by the end of this year. In addition, our marketing submission for migalastat in Europe is already being reviewed under Accelerated Assessment and an Opinion is expected by year-end. With defined regulatory pathways for migalastat in both the U.S. and EU, we are rapidly executing our global strategy to bring this novel personalized medicine to as many people living with Fabry disease as quickly as possible."

About Fabry Disease

Fabry disease is an inherited lysosomal storage disorder caused by deficiency of an enzyme called alpha-galactosidase A (alpha-Gal A). The primary biological function of alpha-Gal A is to degrade specific lipids in lysosomes, including globotriaosylceramide (referred to here as GL-3 and also known as Gb3). Lipids that can be degraded by the action of alpha-Gal A are called "substrates" of the enzyme. Reduced or absent levels of alpha-Gal A activity lead to the accumulation of GL-3 in the affected tissues, including the central nervous system, heart, kidneys, and skin. This accumulation of GL-3 is believed to cause the various symptoms of Fabry disease, including pain, kidney failure, and increased risk of heart attack and stroke.
