Key Factors Driving the Growth of the Pompe Disease Market 

• Rising Disease Awareness and Diagnosis: Greater awareness of Pompe disease among healthcare professionals and patients is supporting earlier identification of the condition. Advances in newborn screening and diagnostic testing are also helping detect previously underdiagnosed cases.
• Increasing Adoption of Enzyme Replacement Therapy: ERT remains a key treatment approach for Pompe disease, particularly for improving survival and disease management. Continued use of approved therapies is supporting market demand, while treatment optimization is expanding the addressable patient population.
• Growing Newborn Screening Programs: Expansion of newborn screening initiatives is enabling earlier detection of infantile-onset Pompe disease before severe symptoms develop. Earlier diagnosis can facilitate prompt treatment initiation and improve clinical management.
• Expansion of Genetic and Molecular Diagnostics: Advances in genetic testing are making it easier to confirm GAA gene mutations and distinguish Pompe disease from other neuromuscular disorders. Improved diagnostic capabilities are enabling earlier, more accurate patient identification.
• Increasing Clinical Research and Pipeline Activity: Growing investment in Pompe disease research is driving the development of novel therapeutic candidates including MZE001 (S-606001; Shionogi and Maze Therapeutics), AT845 (Astellas Pharma), AB-1009 [AskBio (Bayer)], DNL952 (Denali Therapeutics), ABX1100 (Aro Biotherapeutics), GC301 (GeneCradle), and others. Clinical trials targeting both infantile- and late-onset disease are strengthening the future market pipeline.

Aparna Thakur, Project Manager of Forecasting & Analytics at DelveInsight, said MZE001 could be used as a monotherapy or as an add-on to enzyme replacement therapy, the current standard of care, to improve treatment for patients with Pompe disease.

Pompe Disease Market Analysis

• Treatment for Pompe disease is disease-specific, symptomatic, and supportive, and requires a coordinated, multidisciplinary approach involving specialists experienced in managing neuromuscular disorders. 
• Enzyme Replacement Therapy (ERT) remains the mainstay of treatment and involves administering a synthetic form of the deficient Acid Alpha-glucosidase (GAA) enzyme to compensate for the enzyme deficiency.
• Approved therapies for Pompe disease include POMBILITI + OPFOLDA (Amicus Therapeutics), NEXVIAZYME (Sanofi), and LUMIZYME/MYOZYME (Sanofi).
• For many years after its approval, LUMIZYME/MYOZYME remained the standard of care for patients with Pompe disease. 
• While the treatment has been lifesaving, many patients receiving LUMIZYME/MYOZYME infusions continue to experience disease progression and require higher doses, highlighting the persistent unmet need in Pompe disease management. 
• The second-generation ERT, NEXVIAZYME, was developed to achieve greater uptake into target cells, thereby enhancing the therapeutic response. 
• Since its licensure, patients have increasingly transitioned from LUMIZYME/MYOZYME to NEXVIAZYME to improve clinical outcomes and help prevent further disease decline.
• The Pompe disease pipeline includes several potential therapies in development. Companies such as Shionogi and Maze Therapeutics (MZE001 [S-606001]), Astellas Pharma (AT845), Aro Biotherapeutics (ABX1100), and AskBio/Bayer (AB-1009) are actively pursuing research and development programs for Pompe disease.

Pompe Disease Competitive Landscape

Some of the Pompe disease medications under development include MZE001 (S-606001; Shionogi and Maze Therapeutics), AT845 (Astellas Pharma), AB-1009 [AskBio (Bayer)], DNL952 (Denali Therapeutics), ABX1100 (Aro Biotherapeutics), GC301 (GeneCradle), and others.

Shionogi and Maze Therapeutics' MZE001 is an oral glycogen synthase (GYS1) inhibitor being developed to treat Pompe disease by reducing the accumulation of disease-causing glycogen. The U.S. FDA has granted MZE001 Rare Pediatric Disease Designation (RPDD).

Astellas Pharma's AT845 is an investigational AAV-based gene replacement therapy designed to deliver a functional copy of the GAA gene directly to muscle cells in adults with late-onset Pompe disease (LOPD). The company has also entered into an exclusive licensing and development agreement for IdeXork (Xork), a potential next-generation immunoglobulin G (IgG) protease. Astellas will develop Xork for use in combination with AT845 as a treatment for adults with LOPD.

Genecradle Therapeutics' GC301 is an investigational Pompe disease therapy that uses an AAV vector to deliver a GAA gene expression cassette. Administered as a single intravenous injection, GC301 is designed to systemically compensate for GAA enzyme deficiency and target key affected tissues, including the liver, heart, skeletal muscle, and central nervous system. A single dose is intended to support long-term GAA enzyme expression, with the potential to improve motor function and quality of life while addressing the underlying cause of Pompe disease.

The anticipated launch of these emerging therapies are poised to transform the Pompe disease market landscape in the coming years. As these cutting-edge therapies continue to mature and gain regulatory approval, they are expected to reshape the Pompe disease market landscape, offering new standards of care and unlocking opportunities for medical innovation and economic growth.
