Gene Therapy Global Market is Projected to Grow at a CAGR of ~19% by 2028

The approach has become increasingly important across inherited disorders, hematological conditions, neurological diseases, ophthalmological disorders, and certain cancers. Depending on the therapeutic strategy, genetic material may be delivered directly into the patient’s body or cells may be modified outside the body before being administered back to the patient.

Viral vectors remain an important delivery technology, while non-viral approaches are also being investigated to improve safety, scalability, and targeting. Gene-editing technologies such as CRISPR/Cas9 have further expanded the possibilities for precise modification of disease-associated genes.

Despite its therapeutic promise, gene therapy development remains complex. High manufacturing costs, delivery challenges, durability of treatment effects, potential safety concerns, and ethical considerations can influence development and commercialization. Continued research and regulatory experience are expected to play an important role in addressing these challenges.

Gene Therapy Market Insights and Regional Growth

Gene Therapy Market Dynamics and Growth Drivers

The increasing prevalence and diagnosis of genetic and rare diseases represents a major factor supporting the expansion of the gene therapy market. Conditions such as hemophilia, spinal muscular atrophy, inherited retinal disorders, and other genetic diseases have created significant demand for therapies capable of addressing underlying disease mechanisms.

The approval and commercialization of gene therapies for conditions such as hemophilia B have demonstrated the potential of genetic medicines to provide long-term therapeutic benefits. At the same time, continued innovation in vector technology and gene-editing platforms is encouraging developers to explore broader therapeutic applications.

The expanding clinical pipeline is another important contributor to market growth. Investigational programs are increasingly targeting neurological, ophthalmological, musculoskeletal, hematological, and autoimmune diseases, broadening the potential addressable population for gene therapy.
