Migalastat

Migalastat is a member of piperidines.|Fabry disease is a rare, progressive genetic disorder characterized by a defective GLA gene that causes a deficiency in the enzyme alpha-Galactosidase A (alpha-Gal A). This enzyme is responsible for breaking down glycosphingolipid substrate that, when deficient in patients with Fabry disease, builds up in the blood vessels, the kidneys, the nerves, the heart, and other organs. In the U.S., it is estimated that more than 3,000 people are living with Fabry disease, and an estimated more than 50 percent of these diagnosed patients are currently untreated. Migalastat (approved and sold under Amicus Therapeutics' brand name Galafold) is subsequently an oral pharmacological chaperone of alpha-Gal A for the treatment of Fabry disease in adults who have amenable GLA variants. In these patients, migalastat works by stabilizing the body’s own dysfunctional alpha-Gal A enzyme so that it can clear the accumulation of glycosphingolipid disease substrate. Globally, it is estimated that approximately 35 to 50 percent of Fabry patients may have amenable GLA variants that are treatable with migalastat. Given the rarity of Fabry disease and the proportion of Fabry disease patients that could benefit from migalastat therapy, Amicus Therapeutics' brand name Galafold was approved using the Accelerated Approval pathway, under which the FDA may approve drugs for serious conditions where there is an unmet medical need and where a drug is shown to have certain effects that are reasonably likely to predict a clinical benefit to patients. A further study is required to verify and describe the clinical benefits of Galafold, and the sponsor will be conducting a confirmatory clinical trial of Galafold in adults with Fabry disease. Additionally, Galafold was alzo granted Priority Review designation, under which the FDA’s goal is to take action on an application within six months of application filing where the agency determines that the drug, if approved, would provide a significant improvement in treating, diagnosing or preventing a serious condition over available therapies. Galafold also received Orphan Drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases. As of August 2018, migalastat under Amicus Therapeutics' brand name Galafold is currently approved in Australia, Canada, European Union, Israel, Japan, South Korea, Switzerland, and the United States.|Migalastat is pharmacologic chaperone of alpha-galactosidase the intrahepatic enzyme that is deficient in Fabry disease. Clinical experience with migalastat is limited, but it not been linked to serum enzyme elevations during therapy or to instances of clinically apparent acute liver injury.
