Enzyme Replacement Therapy Market Dynamics:

Drivers:

• Market Growth is Driven by the Rising Prevalence of Rare Lysosomal Storage Disorders (LSDs)

This ERT is mainly used for lysosomal storage disorders, which are a rare but severe genetic disease caused by enzyme deficiency in a number of metabolic pathways. The growing incidence of acquired conditions, including Gaucher, Fabry, and Pompe, is also partly due to more screening, which means more diagnoses. Many healthcare systems are now able to diagnose patients at an earlier age and with a higher throughput with genetic testing, along with the increased use of newborn screening programs. With the growing number of patients, there was an increased need for effective treatment methods, such as ERT, leading enzyme replacement therapy market growth.

For instance, according to NIH, Lysosomal Storage Disorders (LSDs) are much common, with the combined incidence ranging from/5000 to 1/8000 births depending on the source. The prevalence of these disorders is largely affected by both ethnicity and geographic region.

• Market Growth is Being Propelled by Government Policies that are Supportive of AS and Orphan Drug Incentives

Various incentives are offered by governments or regulatory entities such as the FDA and EMA to stimulate the discovery and development of effective treatments for rare diseases, including enzyme replacement therapies. The aid consists of an orphan drug designation, which grants tax credits, lowered regulatory fees, and a specified period of market exclusivity. These policies promote research and development of ERTs by pharmaceutical and biotech companies, expediting the entry of new therapies, and expanding the market for these companies.

For instance, Denali Therapeutics announced that the FDA granted Breakthrough Therapy Designation for DNL310 (tividenofusp alfa) for Hunter syndrome in January 2025, representing a significant example of regulatory support of new ERTs. Likewise, GC Biopharma’s GC1130A fast-track designation for Sanfilippo syndrome type A was also awarded in July 2024.

Restraints:

• High Cost of Treatment is One of the Major Restraints i'n the Enzyme Replacement Therapy (ERT) Market

ERT drugs are biologics, a type of drug requiring intricate, complex and resource resource-heavy manufacturing processes. This often results in per-patient annual treatment costs of hundreds of thousands and, in some clinical scenarios, more than a million dollars, depending on the disorder and dosing frequency. These costs represent a huge economic burden for healthcare systems, insurers, and patients in many regions globally, including almost all patients from countries without extensive health insurance coverage or where access to healthcare is predominantly out of pocket. Thus, the cost and availability of ERT pose significant challenges, especially in LMIC, where governmental reimbursement policies may not cover the high price of these therapies. Such a cost prohibition not only restricts uptake but also raises concerns over the sustainability of treatment in the long term and fairness in access to care.
