Amicus Therapeutics Receives Positive CHMP Opinion for Opfolda® (miglustat) for Late-Onset Pompe Disease
European Commission Approval of Opfolda and Commercial Launch of Pombiliti®+ Opfolda®Anticipated in 3Q 2023
Upon Approval, Pombiliti + Opfolda will be the First Two-Component Therapy in the European Union for the Treatment of Adults Living with Late-Onset Pompe Disease
PHILADELPHIA, April 26, 2023 (GLOBE NEWSWIRE) -- Amicus Therapeutics (Nasdaq: FOLD) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion recommending marketing authorization of miglustat, the enzyme stabilizer component of AT-GAA. A decision for miglustat from the European Commission (EC) is expected in the third quarter of 2023, after which the two-component therapy will be fully approved, and the Company will begin the country-by-country reimbursement and launch process. Miglustat will be commercialized under the brand name Opfolda. The biologic component of the two-component therapy, Pombiliti (cipaglucosidase alfa), was approved by the European Commission in March 2023.
Upon approval, Pombiliti + Opfolda will be the first two-component therapy available in the European Union (EU) for the treatment of adults living with late-onset Pompe disease (LOPD). The indication for Opfolda is an enzyme stabilizer of cipaglucosidase alfa long-term enzyme replacement therapy in adults with late-onset Pompe disease (acid α glucosidase [GAA] deficiency).
“With today’s positive CHMP opinion of Opfolda, we are now one step away from bringing this much-needed new treatment to adults living in Europe with late-onset Pompe disease. This was the realization of the hard work and efforts of so many individuals dedicated to the mission of improving the lives of people living with Pompe disease,” said John F. Crowley, Executive Chairman of Amicus Therapeutics, Inc.
"I am immensely proud of our team that has worked tirelessly over the past decade to develop this innovative therapy. We are grateful for the commitment and support from the Pompe community who have helped advance this therapy, especially the patients, families, and physicians who participated in our clinical studies. Based on the strength of the label and our launch readiness, once fully approved we believe there is significant opportunity to bring Pombiliti and Opfolda as the first two-component therapy for adult LOPD patients in Europe, and to establish this novel treatment combination as a potential new standard of care in Pompe disease,” said Bradley Campbell, President and Chief Executive Officer of Amicus Therapeutics, Inc.
“This significant milestone moves Pombiliti and Opfolda closer to the LOPD community, where there is a high medical need for novel treatment options,” said Prof. Benedikt Schoser, Professor of Neurology at Ludwig-Maximillians-University of Munich LMU Department of Neurology. “In clinical studies, Pombiliti and Opfolda has exhibited clinically meaningful and positive changes in the key manifestations of this challenging disease. The CHMP positive opinion and recommended indication reflect this robust body of evidence and gives me further hope for the potential of this innovative therapy for people living with LOPD.”
The CHMP based its positive opinion on clinical data from the Phase 3 PROPEL pivotal study, the only randomized, controlled trial in LOPD to include patients in the high unmet need ERT-experienced population, in addition to ERT-naïve patients.
About Pombiliti® + Opfolda®
Pombiliti + Opfolda, also known as AT-GAA, is an investigational two-component therapy that consists of cipaglucosidase alfa, a bis-M6P-enriched rhGAA that facilitates high-affinity uptake through the M6P receptor while retaining its capacity for processing into the most active form of the enzyme, and the oral enzyme stabilizer, miglustat, that’s designed to minimize loss of enzyme activity in the blood. In clinical studies, AT-GAA was associated with demonstrated improvements in both musculoskeletal and respiratory measures.
About Pompe Disease
Pompe disease is an inherited lysosomal disorder caused by deficiency of the enzyme acid alpha-glucosidase (GAA). Reduced or absent levels of GAA lead to accumulation of glycogen in cells, which is believed to result in the clinical manifestations of Pompe disease. Pompe disease ranges from a rapidly fatal infantile form with significant impacts to heart function, to a more slowly progressive, late-onset form primarily affecting skeletal muscle and progressive respiratory involvement. Late-onset Pompe disease can be severe and debilitating, including progressive muscle weakness throughout the body, particularly the skeletal muscles and muscles controlling breathing, that worsens over time.

Important Safety Information
Pombiliti (cipaglucosidase alfa) Important Safety Information
Posology and Method of Administration: Pombiliti must be used in combination with miglustat 65 mg hard capsules. The recommended dose of Pombiliti is 20 mg/kg of body weight every other week. The Pombiliti infusion should start 1 hour after taking miglustat capsules. Paediatric population: The safety and efficacy of Pombiliti in combination with miglustat therapy in paediatric patients less than 18 years old have not yet been established. No data are available. Contraindications: Life-threatening hypersensitivity to the active substance, or to any of the excipients. Contraindication to miglustat. Anaphylaxis and infusion-associated reactions (IARs): Serious anaphylaxis and IARs have occurred in some patients during infusion and following infusion with Pombiliti. Premedication with oral antihistamine, antipyretics, and/or corticosteroids may be administered to assist with signs and symptoms related to IARs experienced with prior enzyme replacement therapy (ERT) treatment. Reduction of the infusion rate, temporary interruption of the infusion, symptomatic treatment with oral antihistamine, or antipyretics, and appropriate resuscitation measures should be considered to manage serious IARs. If anaphylaxis or severe allergic reactions occur, infusion should be immediately paused, and appropriate medical treatment should be initiated. The current medical standards for emergency treatment of anaphylactic reactions are to be observed and cardiopulmonary resuscitation equipment should be readily available. The risks and benefits of re-administering Pombiliti following anaphylaxis or severe allergic reaction should be carefully considered, and appropriate resuscitation measures made available. Risk of acute cardiorespiratory failure in susceptible patients: Patients with acute underlying respiratory illness or compromised cardiac and/or respiratory function may be at risk of serious exacerbation of their cardiac or respiratory compromise during infusions. Appropriate medical support and monitoring measures should be readily available during Pombiliti infusion. Immune complex-related reactions: Immune complex-related reactions have been reported with other ERTs in patients who had high IgG antibody titres, including severe cutaneous reactions and nephrotic syndrome. If immune complex-related reactions occur, discontinuation of the administration of Pombiliti should be considered and appropriate medical treatment should be initiated. The risks and benefits of re-administering Pombiliti following an immune complex-related reaction should be reconsidered for each individual patient. Contraception in females: Reliable contraceptive measures must be used by women of childbearing potential during treatment with Pombiliti in combination with miglustat, and for 4 weeks after discontinuing treatment. Pregnancy: Pombiliti in combination with miglustat therapy is not recommended during pregnancy. Breast feeding: It is not known if Pombiliti and miglustat are secreted in human breast milk. A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from Pombiliti in combination with miglustat therapy taking into account the benefit of breast-feeding for the child and the benefit of therapy for the woman. Summary of the safety profile: The most commonly reported adverse reactions only attributable to Pombiliti were chills (4.0%), dizziness (2.6%), flushing (2.0%), somnolence (2.0%), chest discomfort (1.3%), cough, (1.3%), infusion site swelling (1.3%), and pain (1.3%). Reported serious adverse reactions only attributable to Pombiliti were urticaria (2.0%), anaphylaxis (1.3%), pyrexia (0.7%), presyncope (0.7%), dyspnoea (0.7%), pharyngeal oedema (0.7%), wheezing (0.7%), and hypotension (0.7%).
