Amryt Receives Complete Response Letter from the FDA for Oleogel-S10 NDA

DUBLIN, Ireland, and Boston, MA, February 28, 2022, Amryt (Nasdaq: AMYT), a global, commercial-stage biopharmaceutical company dedicated to acquiring, developing and commercializing novel treatments for rare diseases, today announced it has received a Complete Response Letter (CRL) from the US Food and Drug Administration (FDA) regarding its New Drug Application (NDA) for Oleogel-S10, for the treatment of the cutaneous manifestations of Dystrophic and Junctional Epidermolysis Bullosa (EB), a rare, genetic skin disease characterized by extremely fragile skin that blisters and tears from minor friction or trauma for which there are no approved treatment options.

The FDA communicated that it had completed its review of the application and has determined that the application cannot be approved in its present form. The FDA has asked Amryt to submit additional confirmatory evidence of effectiveness for Oleogel-S10 in EB. Amryt intends to discuss with the FDA the nature of the data required to address the Agency’s concerns.

Dr Joe Wiley, CEO of Amryt Pharma, commented: “We are extremely disappointed by this decision and we remain committed to our goal of bringing Oleogel-S10 to patients. EB is a devastating disease with no approved treatment options and the EB community is desperate for a therapy. The EASE study was the largest randomized clinical trial ever conducted in this disease and the first Phase 3 study to meet its primary endpoint. We are committed to working collaboratively with the FDA to identify the most expeditious pathway towards a potential approval for this important therapy.”

About Epidermolysis Bullosa
EB is a rare and devastating group of hereditary disorders of the skin, mucous membranes, and internal epithelial linings characterized by extreme skin fragility and blister development. Patients with severe forms of EB suffer from severe, chronic blistering, ulceration and scarring of the skin, mutilating scarring of the hands and feet, joint contractures, strictures of the esophagus and mucous membranes, a high risk of developing aggressive squamous cell carcinomas, infections and risk of premature death. The global market opportunity for EB is estimated by the Company to be in excess of $1.0 billion.

Amryt’s commercial business comprises three orphan disease products – metreleptin (Myalept®/ Myalepta®); oral octreotide (Mycapssa®); and lomitapide (Juxtapid®/ Lojuxta®).

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®) as an adjunct to diet 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. For additional information, please follow this link.

Mycapssa® (octreotide capsules) is approved in the US for long-term maintenance therapy in acromegaly patients who have responded to and tolerated treatment with octreotide or lanreotide. Mycapssa® is the first and only oral somatostatin analog approved by the FDA. Mycapssa® has also been submitted to the EMA and is not yet approved in Europe. For additional information, please follow this link.

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, Colombia, Argentina and Japan (under the trade name Juxtapid®) and in the EU, Israel, Saudi Arabia and Brazil (under the trade name Lojuxta®).

Amryt's lead development candidate, Oleogel-S10 is a potential treatment for the cutaneous manifestations of Junctional and Dystrophic 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 Oleogel-S10. The product does not currently have regulatory approval to treat EB.

Amryt’s pre-clinical gene therapy candidate, AP103, offers a potential treatment for patients with Dystrophic EB, and the polymer-based delivery platform has the potential to be developed for the treatment of other genetic disorders.

Amryt also intends to develop oral medications that are currently only available as injectable therapies through its Transient Permeability Enhancer (TPE^®) technology platform. For more information on Amryt, including products, please visit www.amrytpharma.com.
