"The approval of Galafold represents a significant step forward for the Canadian Fabry community," stated John F. Crowley, Chairman and Chief Executive Officer of Amicus Therapeutics, Inc. "We look forward to launching Galafold in Canada to further advance our mission of expanding global access to Galafold for people living with Fabry disease who have amenable mutations."
Health Canada approved Galafold based on clinical data from two Phase 3 pivotal studies in both treatment naïve (Study 011 , or FACETS) and enzyme replacement therapy (ERT) switch patients (Study 012 , or ATTRACT), as well as an ongoing long-term extension study and overall body of evidence. Fabry is a rare genetic disease and potentially life-threatening condition caused by the accumulation of disease substrate (globotriaosylceramide, GL-3) in the lysosome due to a dysfunctional or deficient enzyme. Galafold works by stabilizing the body's own dysfunctional enzyme, so it can clear the accumulation of disease substrate in patients who have amenable mutations. An amenable mutation is one that is responsive to therapy with Galafold based on a proprietary in vitro assay (Galafold Amenability Assay).
"Following more than a decade of experience treating Fabry patients with Galafold in the clinical setting, I am pleased that Fabry patients in Canada who have amenable mutations will soon have access to this important and differentiated medicine," said Dr. Daniel Bichet, Full Professor and Section Head, Renal Function & Transport Physiology, University of Montreal, and Principal Investigator for Canada in the Galafold clinical studies. "Galafold has a unique mechanism of action that is rooted in the underlying genetics of Fabry disease. With approximately 270 mutations identified as amenable to this chaperone therapy in Canada, there are many patients who could potentially benefit from this new treatment option."
Julia Alton, Executive Director of the Canadian Fabry Association, stated, "Following Health Canada's approval of Galafold, we are delighted that the Fabry community in Canada will soon have access to the first new Fabry treatment option in nearly fifteen years. Amicus has partnered with the Fabry community for more than a decade to incorporate the needs of patients and physicians into the Galafold development process and we look forward to the differentiated treatment choice that Galafold will offer to Fabry patients in Canada who have amenable mutations."
About Galafold™ and Amenable Mutations
Galafold™ (migalastat) is a first-in-class chaperone therapy approved in Canada as a monotherapy for Fabry disease in patients with amenable mutations. Galafold 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) was used to classify more than 800 known GLA mutations as "amenable" or "not amenable" to treatment with Galafold. The Canadian label includes 270 GLA mutations that have been identified and determined to be amenable in Canada based on the Galafold Amenability Assay.
Healthcare providers in Canada may access the website www.Galafoldamenabilitytable.com  to quickly and accurately identify which mutations are categorized as "amenable" or "not amenable" to Galafold. Amicus expects to submit additional updates to the Canadian label as additional GLA mutations are identified and tested in the Galafold Amenability Assay.
Important Canadian Safety Information
Treatment with Galafold should be initiated and supervised by specialists experienced in the diagnosis and treatment of Fabry disease. Galafold is not recommended for use in patients with a non-amenable mutation.
For further important safety information for Galafold, including the indications, method of administration, special warnings, drug interactions and adverse drug reactions, please see the Canadian Prescribing Information for Galafold available from the Health Canada website here .
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.
