Amryt Provides Update on Regulatory Review Process for Oleogel-S1

FDA PDUFA goal date extended by three months to February 28, 2022

EMA CHMP opinion now expected in January 2022

DUBLIN, Ireland, and Boston MA, November 23, 2021, Amryt (Nasdaq: AMYT, AIM: AMYT), a global, commercial-stage biopharmaceutical company dedicated to acquiring, developing and commercializing novel treatments for rare diseases, today announces that the US Food and Drug Administration (“FDA”) has extended the review period for the New Drug Application (“NDA”) for Oleogel-S10 for the treatment of 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.

The FDA extended the Prescription Drug User Fee Act (“PDUFA”) goal date to allow time to review additional analyses of data previously submitted by Amryt. The submission of this additional information has been determined by the FDA to constitute a Major Amendment to the NDA, resulting in an extension of the PDUFA goal date by three months to February 28, 2022. This is a standard review extension period to allow the FDA additional time to review information already submitted by Amryt. At the same time, the FDA also issued a new Information Request regarding existing study data in order to continue the FDA’s evaluation of Amryt’s NDA.

In June 2021, Amryt received confirmation from the FDA that its NDA for Oleogel-S10 had been accepted and granted priority review. The PDUFA goal date extension has no impact on the priority review status of Oleogel-S10.

The European Medicines Agency (“EMA”) review process for Oleogel-S10 in EB is ongoing and Amryt is in the process of responding to the remaining Major Objections in the List of Outstanding Issues sent by the EMA. The Committee for Medicinal Products for Human Use (“CHMP”) opinion is now expected in January 2022.

Dr Joe Wiley, CEO of Amryt Pharma, commented: “We are well positioned to address these regulatory requests from our existing data within the time periods required and we look forward to our continued productive discussions as the regulatory agencies complete their review. If approved, we are confident in the potential for Oleogel-S10 to be an effective therapy for patients suffering from this terrible condition and are ready to launch what will be the first to market novel therapy in EB.”

Amryt’s previously issued revenue guidance for FY 2021 in the range of $220M - $225M which represents growth of 20% to 23% on FY 2020 is unaffected by the new regulatory timelines.

About Epidermolysis Bullosa

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.
