Approved therapies like Zolgensma (Novartis), Luxturna (Roche), and Zynteglo (Bluebird Bio) have validated gene therapy’s clinical efficacy and commercial viability, encouraging investment and accelerating research into broader applications.
As of 2025, over 1,000 gene therapy clinical trials are underway globally, spanning indications from oncology and cardiovascular disease to rare genetic disorders. The momentum is supported by technological strides in viral vector engineering, CRISPR/Cas9 gene editing, non-viral delivery systems, and synthetic biology. Governments and regulatory agencies, particularly the FDA and EMA, are actively fostering innovation with fast-track, orphan drug, and breakthrough therapy designations. With a growing pipeline, supportive policies, and expanding infrastructure, the global gene therapy market is poised to redefine 21st-century medicine.

One of the most influential growth drivers in the gene therapy market is the increasing recognition and diagnosis of rare and genetic disorders globally. According to estimates by the Global Genes Project, more than 400 million people worldwide are living with rare diseases, many of which have genetic origins and lack effective treatments. Traditional therapeutic options often involve lifelong management, repeated interventions, and high healthcare costs.
Gene therapy offers a single-intervention cure or long-term remission for such conditions. For instance, Zolgensma, approved by the FDA in 2019, treats SMA Type 1 with a single intravenous infusion and has been shown to transform fatal prognosis into near-normal development. The success of such therapies has catalyzed research into similar monogenic diseases such as Sickle Cell Disease (SCD), Beta-Thalassemia, and Hemophilia A & B. As next-generation sequencing (NGS) makes genetic screening more accessible, early identification of eligible patients will drive demand for targeted gene therapies.
Despite the remarkable clinical potential, the high cost of gene therapy presents a formidable barrier to market adoption and accessibility. Approved therapies like Zolgensma (~$2.1 million) and Zynteglo (~$2.8 million) represent some of the most expensive treatments globally. While these therapies often replace a lifetime of medical interventions, the upfront cost is prohibitive for many healthcare systems and insurers.
This economic challenge is further amplified in low- and middle-income countries, where reimbursement frameworks and healthcare infrastructure are underdeveloped. The complexity of manufacturing, storage, and logistics—particularly with autologous therapies—contributes to elevated prices. Payers are exploring value-based contracts, milestone payments, and outcomes-based reimbursement models, but wide-scale consensus remains elusive. Without scalable pricing and access strategies, the reach of gene therapy may remain limited to high-income settings in the short term.
A transformative opportunity lies in applying gene therapy beyond rare and monogenic diseases into more common and chronic conditions. Current research is exploring gene silencing, gene replacement, and genome editing to treat prevalent disorders such as heart failure, type 2 diabetes, macular degeneration, and Alzheimer’s disease. These expansions promise to multiply the addressable patient base significantly and offer new business models for scalability.
For example, REGENXBIO is developing RGX-314 for wet age-related macular degeneration (wAMD), a common cause of blindness in the elderly. Unlike current treatments requiring monthly intravitreal injections, RGX-314 offers a one-time dose. Similarly, companies like Verve Therapeutics are working on in vivo gene editing therapies for cardiovascular diseases, targeting PCSK9 and ANGPTL3 genes. These new indications, if successful, will not only diversify the gene therapy portfolio but also establish its role in mainstream chronic care.
AAV (Adeno-Associated Virus) vectors dominate the market, owing to their relative safety, low immunogenicity, and ability to achieve long-term gene expression. AAVs are commonly used in therapies targeting the eye, muscle, and central nervous system, as demonstrated by Luxturna, Zolgensma, and several ongoing programs. AAVs can be tailored for tissue-specific delivery and have a well-understood safety profile, making them a preferred choice for systemic and localized gene delivery.
Non-viral plasmid vectors are the fastest-growing segment, particularly due to their scalability, lower cost, and reduced immune response compared to viral vectors. With improvements in delivery technologies such as electroporation, nanoparticles, and lipid-based vectors, non-viral approaches are gaining attention for larger genes or repeat-dosing applications. Companies like Poseida Therapeutics and GenScript ProBio are pioneering this area, supported by increasing demand for safer, more affordable platforms.
Spinal Muscular Atrophy (SMA) dominates the indication segment, largely due to the blockbuster success of Zolgensma, the first FDA-approved gene therapy for SMA. SMA Type 1, one of the most severe forms of the disease, previously led to death or lifelong ventilation in early childhood. Zolgensma has reversed this prognosis with a single intravenous dose. Its efficacy and media attention have galvanized interest and investment in other neuromuscular gene therapy programs.
Beta-Thalassemia and Sickle Cell Disease (SCD) are the fastest-growing indications, with therapies like Zynteglo and exagamglogene autotemcel (exa-cel) from CRISPR Therapeutics/Vertex paving the way. These conditions affect millions globally, particularly in regions like South Asia, the Middle East, and Sub-Saharan Africa. The potential to reduce or eliminate transfusion dependency or painful vaso-occlusive crises makes gene therapy highly desirable. Clinical trials continue to show encouraging results, and broader approvals are expected in 2025–2026.
Intravenous administration dominates the route of delivery, especially for systemic diseases like SMA, SCD, and beta-thalassemia. Intravenous infusion allows for widespread gene distribution throughout the body and is the standard method for autologous cell therapies like CAR-T and gene-modified stem cell therapies. Its well-established clinical use and manageable infusion protocols have made it the go-to approach for many approved and pipeline therapies.
Localized routes (ocular, intrathecal, intramuscular) are the fastest growing, particularly as researchers aim to target specific tissues while minimizing systemic exposure. Intrathecal delivery, for example, is preferred in neurological disorders to bypass the blood-brain barrier, as seen in investigational gene therapies for ALS and Parkinson’s disease. Ocular delivery is common in retinal diseases, where direct injection into the retina maximizes vector efficacy while reducing systemic risk. As targeted delivery technologies evolve, localized routes are expected to grow rapidly.
