Enzyme replacement therapy (ERT) involves replacing a missing or deficient enzyme in a patient’s body to treat a disease. It is usually given through intravenous or other parenteral routes. The enzymes for replacement are either purified human or animal or prepared through recombinant techniques. The enzymes can also be modified to enhance their properties, such as longer half-life, increased potency, resistance to degradation, and targeted action. ERT cannot correct the genetic defect but can maintain the enzyme concentration in the body.
ERT is used to treat rare genetic disorders such as alpha 1 anti-trypsin (A1AT) deficiency, Gaucher disease, adenosine deaminase deficiency, Fabry disease, Hunter syndrome, Pompe disease, etc. The rising prevalence of rare genetic disorders necessitates their treatment, increasing the demand for ERT. The growing research and development activities facilitate the development of potential enzymes for treating other disorders. The burgeoning biotechnology sector leads to advancements in current techniques for preparing enzymes. The advent of advanced technologies results in more efficient techniques and better outcomes.
Artificial intelligence (AI) and machine learning (ML) tools have become integral parts of the healthcare ecosystem, driving the latest innovation. In molecular biology and biotechnology, AI and ML have been defined as playing vital roles in various aspects, from discovery to clinical applications. AI and ML tools can be used to predict the structures of proteins and enzymes. They can also predict the functions and interactions and aid researchers in designing novel enzymes. Apart from determining the properties of enzymes, they assist in manipulating the enzymes to improve their potency and overall functions. They also aid in the creation of safer and more effective therapeutics for ERT. They can also predict the response of enzymes in patients before administration.
Advancements in Recombinant Technology
The latest advancements in recombinant technology are a major growth factor in the enzyme replacement therapy market. Recombinant DNA technology is a method used to combine DNA from different species or to create genes with new functions. It is used to develop enzymes for ERT. Recombinant technology produces enzymes that are derived from continuous human, animal, or plant cells. This technology enables researchers to modify enzymes by manipulating the genes producing those enzymes, improving their functions, enhancing potency, and minimizing systemic adverse reactions. The recent advancements in recombinant technology with technological advancements potentiate the demand for creating novel enzymes. Recombinant technology is a rapidly evolving field, with researchers all over the world creating novel methodologies and modified products for treating several rare disorders.
Alternative Methods
The major challenge of the enzyme replacement therapy market is the availability of alternative methods. Other treatment options for patients with enzyme deficiencies include substrate reduction therapy, gene therapy, and bone marrow-derived stem cell transplantation. The latest innovations in such novel and emerging therapies and their growing demand reduce the demand for ERT, hindering market growth.
Growing Research and Development
The future of the enzyme replacement therapy market is promising, driven by the latest innovations in therapies. The current research involves extended applications of the present and novel enzymes in various disorders other than rare genetic disorders. ERT is being studied to treat cancer, neurodegenerative diseases, joint problems, inflammation, and infections. Several researchers are also investigating to overcome potential challenges faced during conventional ERT. Enzymes are modified to improve their characteristics and their binding ability with various biomolecules. Moreover, novel drug delivery systems are currently being developed to provide more targeted action to patients. The growing demand for nanoparticles due to their ability to provide desired pharmacokinetic properties promotes their use in ERT. Other novel drug delivery systems for ERT include virosomes, liposomes, extracellular vesicles, and erythrocytes.
By product, the imiglucerase segment held a dominant presence in the enzyme replacement therapy market in 2024. Imiglucerase is an enzyme that is administered to patients with Type 1 Gaucher’s disease. It can be prescribed to adults and pediatric patients of more than 2 years. The rising prevalence of Gaucher’s disease promotes the segment’s growth. It has an excellent safety profile, hence making it a preferred choice for treating Gaucher’s disease.
By product, the agalsidase beta segment is anticipated to grow with the highest CAGR in the market during the studied years. Agalsidase beta is an enzyme used to treat Fabry disease. The rising prevalence of Fabry disease increases the demand for agalsidase beta. It has a long duration of action and a wide therapeutic index. Hence, its pharmacodynamic properties promote its usage, augmenting the segment’s growth. The increasing awareness about the disease and its treatment and advancements in diagnostics also boost the segment’s growth.
By therapeutic condition, the Gaucher disease segment led the global enzyme replacement therapy market in 2024. Gaucher’s disease is a rare genetic disorder that occurs due to the accumulation of glucocerebroside in cells and certain organs. The rising prevalence and the growing research and development activities fuel the segment’s growth. It is estimated that Gaucher’s disease results in 0.9 cases per 100,000 inhabitants globally. The segmental growth is also driven by improved diagnosis, timely initiation of treatment, and appropriate monitoring.

Mucopolysaccharidosis (MPS) is a group of rare inherited metabolic diseases with 7 subtypes. Patients suffering from MPS have various physical and neurological symptoms. The increasing prevalence of MPS and its complexity contribute to the segment’s growth.
By route of administration, the parenteral segment held the largest share of the enzyme replacement therapy market in 2024. Parenteral administration of enzymes helps to avoid the first-pass metabolism, resulting in 100% bioavailability of the enzyme. ERT is usually given through the intravenous route. Enzymes administered through this route provide a faster onset of action. Additionally, parenteral drug administration has better control over the dose and rate of medication, generating better pharmacodynamic and pharmacokinetic profiles. These advantages propel the segment’s growth.
