Approves Pombiliti (cipaglucosidase alfa-atga) + Opfolda (miglustat)

 

PHILADELPHIA, Sept. 28, 2023 (GLOBE NEWSWIRE) -- Amicus Therapeutics (Nasdaq: FOLD) today announced that the U.S. Food and Drug Administration (FDA) has approved Pombiliti™ (cipaglucosidase alfa-atga) + Opfolda™ (miglustat) 65mg capsules. This two-component therapy is indicated for adults living with late-onset Pompe disease (LOPD) weighing ≥40 kg and who are not improving on their current enzyme replacement therapy (ERT).

Late-onset Pompe disease is a rare, debilitating, and life-threatening lysosomal disorder caused by a deficiency of the enzyme acid alpha-glucosidase (GAA). Reduced levels of GAA lead to the accumulation of the substrate glycogen in the lysosomes of muscle cells and glycogen buildup causes muscle damage. Disease severity ranges across a spectrum, with predominant manifestations such as skeletal muscle weakness and progressive respiratory involvement.1

Pombiliti + Opfolda is a unique two-component therapy. Pombiliti is a recombinant human GAA enzyme (rhGAA) naturally expressed with high levels of bis-M6P (Mannose 6-Phosphate), designed for increased uptake into muscle cells. Once in the cell, Pombiliti can be properly processed into its most active and mature form to break down glycogen. Opfolda is an enzyme stabilizer designed to stabilize the enzyme in the blood.

“Today’s FDA approval of Pombiliti and Opfolda is a testament to the power of science, medicine, and our passionate determination to improve the lives of people living with Pompe disease. This approval embodies our Amicus spirit, passion, and resilience and is a very meaningful step for the Pompe community. I am just so immensely proud of our team, and so very grateful to everyone who has worked to bring this medicine to this approval. Most especially to all of the people living with Pompe around the world,” said John F. Crowley, Executive Chairman of Amicus Therapeutics, Inc.

Bradley Campbell, President and Chief Executive Officer of Amicus Therapeutics, Inc., stated, “The FDA approval of Pombiliti and Opfolda is a major milestone for Amicus. We are grateful to the Pompe community, particularly the patients, caregivers, families, researchers, and physicians who have contributed to the development process through their commitment to our clinical studies. Today’s approval is also a testament to Team Amicus’ extraordinary dedication to patients and our ability to execute on our vision to bring new therapies to the rare disease community. Our highly experienced team is ready to launch this medicine in the U.S., and we look forward to rapidly bringing this new treatment regimen to all eligible adults living with late-onset Pompe disease who are not improving on their current ERT.”

The FDA approval was based on clinical data observed from the Phase 3 pivotal study (PROPEL), the only trial in LOPD to study ERT-experienced participants in a controlled setting.

“The Pompe community continues to face unmet need and limited treatment options. This two-component therapy is an important new treatment for those adults living with late-onset Pompe disease and not improving on current therapies. I am encouraged by the evidence generated over many years of clinical research studying this therapy for ERT-experienced patients living with late-onset Pompe disease,” said Tahseen Mozaffar, MD, Director of the Division of Neuromuscular Diseases in the Department of Neurology at the School of Medicine at UC Irvine and Director of the UC Irvine ALS and Neuromuscular Center, as well as an investigator for the PROPEL study.

“Today’s FDA approval is an extremely important step and acknowledges the potential of Pombiliti and Opfolda,” said Priya Kishnani, MD, Professor of Pediatrics and Chief of Medical Genetics at Duke University School of Medicine and an investigator for the PROPEL study. “I am grateful that eligible patients with late-onset Pompe disease in the U.S. will now have access to additional treatment options.”

“The FDA approval of Pombiliti and Opfolda represents a long-awaited day for people living with late-onset Pompe disease and advocating for additional therapeutic options,” said Tiffany House, President, Acid Maltase Deficiency Association. “Amicus’ long-standing commitment to the Pompe community and rare disease research has led to the development of an important therapy for the Pompe community because patients will now have options.”

Amicus Therapeutics will launch Pombiliti + Opfolda immediately in the U.S. The FDA previously granted Breakthrough Therapy designation for Pombiliti + Opfolda. Pombiliti + Opfolda has also been approved for the treatment of adults with LOPD in the European Union and the United Kingdom.

SAFETY INFORMATION

HYPERSENSITIVITY REACTIONS INCLUDING ANAPHYLAXIS: Appropriate medical support measures, including cardiopulmonary resuscitation equipment, should be readily available. If a severe hypersensitivity reaction occurs, POMBILITI should be discontinued immediately and appropriate medical treatment should be initiated. INFUSION-ASSOCIATED REACTIONS (IARs): If severe IARs occur, immediately discontinue POMBILITI and initiate appropriate medical treatment. RISK OF ACUTE CARDIORESPIRATORY FAILURE IN SUSCEPTIBLE PATIENTS: Patients susceptible to fluid volume overload, or those with acute underlying respiratory illness or compromised cardiac or respiratory function, may be at risk of serious exacerbation of their cardiac or respiratory status during POMBILITI infusion. See PI for complete Boxed Warning. CONTRADICATION: POMBILITI in combination with Opfolda is contraindicated in pregnancy. EMBRYO-FETAL TOXICITY: May cause embryo-fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception during treatment and for at least 60 days after the last dose. Adverse Reactions: Most common adverse reactions ≥ 5% are headache, diarrhea, fatigue, nausea, abdominal pain, and pyrexia.

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 deteriorating infantile form with significant impact 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 with progressive muscle weakness throughout the body that worsens over time, particularly skeletal muscles and muscles that control breathing.1

About Pombiliti + Opfolda

Pombiliti + Opfolda, is a two-component therapy that consists of cipaglucosidase alfa-atga, 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 reduce loss of enzyme activity in the blood.

INDICATIONS AND USAGE

POMBILITI in combination with OPFOLDA is indicated for the treatment of adult patients with late-onset Pompe disease (lysosomal acid alpha-glucosidase [GAA] deficiency) weighing ≥40 kg and who are not improving on their current enzyme replacement therapy (ERT).
