Amryt Granted Orphan Drug Designation by the FDA for AP103

DUBLIN, Ireland, and Boston MA, December 23, 2020, Amryt (Nasdaq: AMYT, AIM: AMYT), a global, commercial-stage biopharmaceutical company dedicated to developing and commercializing novel therapeutics to treat patients suffering from serious and life-threatening rare diseases, is pleased to announce today that the U.S. Food and Drug Administration (“FDA”) has granted orphan drug designation for AP103 for the treatment of Dystrophic Epidermolysis Bullosa ("DEB"). AP103 is based on Amryt's gene-therapy platform technology and offers a potential treatment for patients with DEB, a subset of EB.
The FDA’s Office of Orphan Products Development (“OOPD”) grants orphan drug designation to support the development of medicines for rare diseases, that affect fewer than 200,000 people in the United States. Orphan drug designation may allow Amryt to be eligible for a seven-year period of U.S. Marketing exclusivity upon approval of AP103 and a waiver of the Prescription Drug User Fee Act (“PDUFA”) filing fees, subject to certain conditions.

AP103 is based on a new gene therapy delivery platform, in-licensed by Amryt in March 2018, that utilises a non-viral delivery vector, HPAE (Highly Branched Poly β-Amino Ester), designed to deliver the correct collagen VII gene into skin cells.

Joe Wiley, CEO of Amryt Pharma, commented: "Receiving an orphan drug designation from the FDA for our gene-therapy candidate, AP103, is a significant development for patients suffering from EB and provides additional momentum to our development pipeline. Unlike other gene therapies that rely on viral vectors, AP103 is based on a novel polymer-based topical delivery platform, which we believe offers potential advantages in the gene-therapy field and has potential to be used in other genetic skin conditions.”

About Amryt
Amryt is a biopharmaceutical company focused on developing and delivering innovative new treatments to help improve the lives of patients with rare and orphan diseases. Amryt comprises a strong and growing portfolio of commercial and development assets.

Amryt’s commercial business comprises two orphan disease products.

Amryt's lead development candidate, FILSUVEZ® (Oleogel-S10) is a potential treatment for the cutaneous manifestations of Epidermolysis Bullosa (“EB”), a rare and distressing genetic skin disorder affecting young children and adults for which there is currently no approved treatment. FILSUVEZ® has been selected as the brand name for the product. Amryt does not have regulatory approval for FILSUVEZ® to treat EB. In September and October 2020, Amryt reported positive results from its pivotal global Phase 3 trial in EB. The product has been granted Rare Pediatric Disease Designation and has also received a Fast Track Designation from the U.S. Food and Drug Administration.

Myalept® / Myalepta® (metreleptin) is approved in the US (under the trade name Myalept®) as an adjunct to diet as replacement therapy to treat the complications of leptin deficiency in patients with congenital or acquired generalized lipodystrophy (GL) and in the EU (under the trade name Myalepta®) for the treatment of leptin deficiency in patients with congenital or acquired GL in adults and children two years of age and above and familial or acquired partial lipodystrophy (PL) in adults and children 12 years of age and above for whom standard treatments have failed to achieve adequate metabolic control. Metreleptin is also approved for lipodystrophy in Japan. Generalised and partial lipodystrophy are rare disorders characterised by loss or lack of adipose tissue resulting in the deficiency of the hormone leptin, produced by fat cells and are associated with severe metabolic abnormalities including severe insulin resistance, diabetes, hypertriglyceridemia and fatty liver disease.

Juxtapid®/ Lojuxta® (lomitapide) is approved as an adjunct to a low-fat diet and other lipid-lowering medicinal products for adults with the rare cholesterol disorder, Homozygous Familial Hypercholesterolaemia ("HoFH") in the US, Canada, Columbia, Argentina and Japan (under the trade name Juxtapid®) and in the EU and Brazil (under the trade name Lojuxta®). HoFH is a rare genetic disorder which impairs the body's ability to remove low density lipoprotein ("LDL") cholesterol ("bad" cholesterol) from the blood, typically leading to abnormally high blood LDL cholesterol levels in the body from before birth - often ten times more than people without HoFH - and subsequent aggressive and premature cardiovascular disease.

In March 2018, Amryt in-licensed a pre-clinical gene-therapy platform technology, AP103, which offers a potential treatment for patients with Dystrophic Epidermolysis Bullosa, a subset of EB, and is also potentially relevant to other genetic disorders.
