Pompe Disease Treatment Market Size, Share, Growth, Trends, and Global Industry Analysis: By Treatment Type (Enzyme Replacement Therapy, Gene Therapy), By Age Group Type (Infantile-onset Pompe Disease, Late-Onset Pompe Disease), and  Region Forecast 2020-2031 

Pompe Disease Treatment Market size was valued at US$ 2.3 billion in 2024 and is expected to reach US$ 3.9 billion by 2031, growing at a significant CAGR of 8.0% from 2025-2031. Pompe illness is a genetic metabolic ailment that affects babies and is caused by mutations in the GAA gene, which produces the acid alpha-glucosidase enzyme, which reduces glycogen to a simple form. The lack or mutation of the GAA gene causes glycogen buildup, which causes heart problems, muscle weakness, and liver damage, which can lead to early death.

How will Maze Therapeutics deal benefit the Sanofi?

• May 1st, 2023, Sanofi made a deal with Maze for the MZE001 that treats Pompe patients.  As part of the agreement, Maze will receive US$150 Million in Upfront Cash and Equity Investment, as well as US$ 600 Million upon reaching various development, regulatory, and commercial milestones. This exclusive deal provides Sanofi with access to Maze's GYS1-targeting initiatives and intellectual property.
• Maze (MZE001) basically works on the glycogen synthase (GYS1) inhibitor which is responsible for the glycogen production. Inhibition of this enzyme will play a role in the glycogen production process. Based on the phase 1 clinical study, MZE001 480 mg BID x 10 days safely and substantially reduced acute glycogen synthesis and lowered total muscle glycogen in healthy adults. Combining the ERT + Glycogen Synthase Inhibitor will significantly improve the glycogen breakdown.
• Maze’s deal with Sanofi also gives the French pharmaceutical company exclusive rights to related GYS1-targeting programs and intellectual property. Maze could receive up to $600 million more if certain development, commercial and regulatory milestones are met.
• An interesting aspect of this collaboration is that it will give Sanofi an edge in the Pompe Disease space where it will face stiff competition from Amicus, a two-component therapy which recently received approval from the CHMP. By partnering with Maze, Sanofi is better positioned to gain ground in this Pompe Disease market.
