U.S. FDA Files New Drug Application Under Priority Review for Migalastat for Treatment of Fabry Disease

CRANBURY, N.J., Feb. 12, 2018 (GLOBE NEWSWIRE) -- Amicus Therapeutics (Nasdaq:FOLD) today announced that the U.S. Food and Drug Administration (FDA) has accepted the New Drug Application (NDA) for filing under priority review for the oral precision medicine migalastat HCl (“migalastat”) for the treatment of patients 16 years and older with Fabry disease who have amenable mutations. The Prescription Drug User Fee Act (PDUFA) goal date for the FDA decision is August 13, 2018.

Migalastat previously received both Orphan Drug Designation and Fast Track designation from the U.S. FDA. The FDA’s Priority Review status accelerates the review time from 10 months to a goal of six months from the day of acceptance of filing and is given to drugs that may offer major advances in treatment or may provide a treatment where no adequate therapy exists.

John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics, Inc., stated, “The FDA’s acceptance of our first Amicus NDA submission under priority review is an important step toward a potential oral precision medicine option for the Fabry disease community in the U.S. With more than a decade of experience in treating patients with migalastat globally, our team at Amicus has collaborated with leading Fabry disease experts and patient organization leaders to assemble a robust NDA that emphasizes the breadth of our clinical data and experience delivering migalastat to patients. We look forward to continuing to work collaboratively with FDA to bring this oral precision medicine to patients who may be able to benefit.”

The NDA submission for migalastat is based on clinical data from completed studies, including reduction in disease-causing substrate (GL-3), as well as the totality of data from two Phase 3 pivotal studies in treatment-naïve (Study 011, or FACETS) and enzyme replacement therapy (ERT) switch patients (Study 012, or ATTRACT).

An estimated 3,000 people in the U.S. are currently diagnosed with Fabry disease, more than any other country. Fabry disease is a progressive, inherited lysosomal storage disorder caused by deficiency of an enzyme called alpha-galactosidase A (alpha-Gal A), which is the result of mutations in the GLA gene. The disease causes accumulation of specific lipids, primarily GL-3, in tissues including the heart, kidneys, central nervous system, and skin. This abnormal accumulation can lead to debilitating consequences including pain, kidney failure, heart disease, and stroke.

The European Commission (EC) granted full approval for migalastat, under the trade name Galafold™, as a first line therapy for long-term treatment of adults and adolescents aged 16 years and older with a confirmed diagnosis of Fabry disease (alpha-Gal A deficiency) and who have an amenable mutation. The EC approval was based on clinical data from two Phase 3 pivotal studies (FACETS and ATTRACT), as well as ongoing long-term extension studies.

Outside the EU, migalastat is approved in Switzerland, Israel, Australia, South Korea, and Canada, with regulatory submissions under review in the U.S., Japan, and Taiwan.

About Migalastat and Amenable Mutations

Migalastat is a first-in-class chaperone therapy approved in the European Union as a monotherapy for Fabry disease in patients with amenable mutations. Migalastat works by stabilizing the body’s own dysfunctional enzyme, so it can clear the accumulation of disease substrate in patients who have amenable mutations. A proprietary in vitro assay (Galafold Amenability Assay) has been used to classify more than 1,000 known GLA mutations as “amenable” or “not amenable” to treatment with migalastat. The EU label includes 348 GLA mutations that have been identified and determined to be amenable based on the Galafold Amenability Assay, which represent between 35% and 50% of the currently diagnosed Fabry population.

Healthcare providers in the EU may access the website www.Galafoldamenabilitytable.com to quickly and accurately identify which mutations are categorized as “amenable” or “not amenable” to migalastat. Amicus expects to submit additional updates to the EU label as additional GLA mutations are identified and tested in the Galafold Amenability Assay.

About Fabry Disease

Fabry disease is an inherited lysosomal storage disorder caused by deficiency of an enzyme called alpha-galactosidase A (alpha-Gal A), which is the result of mutations in the GLA gene. 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. Progressive accumulation of GL-3 is believed to lead to the morbidity and mortality of Fabry disease, including pain, kidney failure, heart disease, and stroke. The symptoms can be severe, differ from patient to patient, and begin at an early age. All Fabry disease is progressive and may lead to organ damage regardless of the time of symptom onset.
