FILSUVEZ® CONFIRMED AS GLOBAL BRAND NAME FOR AP101

Amryt, a global, commercial-stage biopharmaceutical company dedicated to commercializing and developing novel therapeutics to treat patients suffering from serious and life-threatening rare diseases, today announces that the global brand name for its lead development product AP101 will be FILSUVEZ®.

Amryt announced on 23 April 2020 that the Company has completed recruitment into its Global Phase 3 clinical study (“EASE”) in Epidermolysis Bullosa (“EB”) and anticipates top line data read out in late Q3 / early Q4 2020.

Establishing the brand name for AP101 is another important step forward in ensuring readiness for the global launch of FILSUVEZ®.

About EB

EB is a rare and distressing genetic skin disorder affecting young children and adults for which there is currently no approved treatment. FILSUVEZ® has been granted Rare Pediatric Disease Designation and has also received a Fast Track Designation from the U.S. Food and Drug Administration (“FDA”). The European and US market opportunity for EB is estimated by the Company to be in excess of $1 billion.

About FILSUVEZ®

FILSUVEZ® is a potential treatment for EB, a rare, chronic and distressing genetic skin disorder that causes the skin layers and internal body linings to separate, affecting infants, children and adults, for which there is currently no approved treatment. It is estimated that the incidence of EB is approximately 1 in 20,000, which implies that there are as many as 30,000 affected individuals in the US and over 500,000 worldwide.

In March 2017, Amryt commenced EASE, a Phase 3 prospective double-blind randomised placebo controlled efficacy and safety study of FILSUVEZ® in patients with dystrophic and junctional EB.  EASE is the largest ever global Phase 3 study conducted in patients with EB, operating across 55 sites in 27 countries globally. In January 2019, Amryt reported the outcome of an unblinded interim efficacy analysis, at which point an Independent Data Monitoring Committee recommended continuing the trial.

In July 2018, FILSUVEZ® was granted Rare Pediatric Disease Designation by the FDA. This means that if a New Drug Application (“NDA”) for FILSUVEZ® is approved, the Company expects to be eligible to receive a Rare Pediatric Disease Priority Review Voucher that can be used, sold or transferred.

FILSUVEZ® was granted Fast Track Designation by the FDA in September 2019. The Fast Track programme is designed to accelerate the development and review of products such as FILSUVEZ®, which are intended to treat serious diseases and for which there is an unmet medical need.  Fast Track Designation enables more frequent communication with the FDA. Amryt has received FDA agreement that FILSUVEZ® can be submitted for a rolling review NDA which is planned in the coming months and will request a priority review in the US.  Amryt also intends to pursue an accelerated assessment in the EU.

FILSUVEZ® has been granted Orphan Drug status for the treatment of EB in the EU and the US. Should FILSUVEZ® be granted approval, it should be entitled to Orphan Drug exclusivity for the treatment of EB, extending seven years in the US and ten years in the EU from the date of approval in the respective jurisdictions.

Dr Joe Wiley, CEO of Amryt Pharma, commented: ”Establishing FILSUVEZ® as the global  brand name for AP101 is another important step in our launch readiness planning for FILSUVEZ®. This alongside our recent completion of recruitment into the EASE study represents further progress as we endeavour to develop a therapy for patients with EB, a rare and distressing genetic skin disorder affecting young children and adults for which there is currently no approved treatment.”

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.

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 (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.

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.

Amryt’s lead development candidate, FILSUVEZ® 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 granted Rare Pediatric Disease Designation and has also received a Fast Track Designation from the FDA. The European and US market opportunity for EB is estimated by the Company to be in excess of $1 billion.

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