“According to a new report published by Introspective Market Research, titled, Enzyme Replacement Therapy Market by Therapy Type, Indication, and End User, The Global Enzyme Replacement Therapy Market Size Was Valued at USD 16.50 Billion in 2024 and is Projected to Reach USD 39.26 Billion by 2035, Growing at a CAGR of 8.2% from 2025–2035.”
The Enzyme Replacement Therapy (ERT) market focuses on biologic treatments designed to supplement or replace deficient enzymes in patients suffering from rare genetic and metabolic disorders. These therapies are primarily used in the treatment of lysosomal storage disorders such as Gaucher disease, Fabry disease, Pompe disease, and mucopolysaccharidoses. ERT offers a targeted therapeutic approach, addressing the underlying cause of disease rather than only managing symptoms, thereby improving patient outcomes and quality of life.
Advancements in biotechnology, recombinant DNA technology, and protein engineering have significantly enhanced the efficacy and safety of enzyme replacement therapies. Compared to conventional treatments, ERT provides disease-modifying benefits, slows disease progression, and reduces long-term complications. Continuous innovation has also led to improved formulations, dosing regimens, and delivery mechanisms.
The market is witnessing steady growth due to increased awareness of rare diseases, rising diagnosis rates, and expanding access to orphan drugs across developed and emerging economies. Supportive regulatory frameworks, incentives for orphan drug development, and growing investments in rare disease research continue to strengthen the global ERT market outlook.
