A powerful driver of the gene therapy starting materials market is the exponential growth of gene therapy candidates in clinical pipelines across the globe. As of early 2025, over 2,000 gene therapy clinical trials are ongoing, targeting a range of therapeutic areas such as cancer, inherited disorders, and cardiovascular diseases. Each of these trials requires substantial quantities of clinical-grade viral vectors, plasmid DNA, and validated cell lines.
For instance, the growing number of AAV-based therapies in phase II/III trials has triggered a corresponding spike in demand for scalable vector manufacturing platforms. Similarly, lentivirus vectors remain the vector of choice for many CAR-T cell therapies. The complexity of these therapeutics and the need for consistency across preclinical, clinical, and commercial stages highlight the critical role of starting materials. The pipeline expansion is not only boosting demand but also encouraging innovation in vector design, cell line development, and GMP-compliant production processes.
Despite the bullish outlook, a significant restraint hampering the market is the limited global capacity for GMP-grade starting material manufacturing. Producing clinical and commercial-grade vectors, plasmids, and cell banks requires highly specialized facilities, rigorous quality controls, and skilled personnel. The sudden rise in demand particularly post-approval of high-profile gene therapies like Zolgensma and Luxturna has exposed capacity bottlenecks across the industry.
For example, many biopharmaceutical companies have faced delays in clinical trial timelines due to the unavailability of AAV or lentivirus materials. Even large CDMOs report order backlogs extending several months. This scarcity not only slows innovation but also inflates production costs, placing added pressure on developers. Until substantial investments are made in upstream infrastructure and talent development, supply chain disruptions may continue to constrain market growth.
A significant opportunity lies in the expansion of gene therapies beyond rare and orphan indications into common, chronic disease areas. Traditionally, gene therapies have targeted monogenic disorders with small patient populations, due to the high cost and complexity of development. However, advances in vector technology, targeted delivery, and regulatory streamlining are paving the way for gene therapies to treat more prevalent conditions like hemophilia, heart failure, and neurodegenerative diseases.
For example, companies like Verve Therapeutics are developing gene-editing therapies for cardiovascular disease, while Sangamo Therapeutics is advancing programs for Parkinson’s and Alzheimer’s. These broader indications will require significantly larger volumes of high-quality starting materials. Suppliers capable of scaling their production while maintaining regulatory compliance will be well-positioned to capture this growing market.
Viral vectors dominated the product landscape, accounting for the highest revenue share in 2024. Among viral vectors, adeno-associated viruses (AAVs) have gained immense popularity due to their low immunogenicity and effectiveness in targeting various tissue types. AAVs are particularly favored in gene therapies for the eye, liver, and central nervous system. Companies like Spark Therapeutics and Novartis have successfully commercialized AAV-based treatments, fueling demand for large-scale vector production.
Plasmid DNA is anticipated to be the fastest growing segment, driven by its essential role as a backbone for vector development and gene delivery. Plasmids are used not only in the manufacture of viral vectors but also in non-viral gene therapies and mRNA-based approaches. With increasing focus on DNA vaccines and transient gene expression systems, the need for optimized, antibiotic-free plasmids is rising. This trend is prompting companies to develop cell-free plasmid manufacturing platforms and synthetic biology solutions.
Clinical therapeutics led the development stage segment, as hundreds of gene therapy candidates progress through Phase I to Phase III clinical trials. The rigorous regulatory framework around clinical-grade materials means high-quality, GMP-compliant viral vectors, plasmids, and cell lines are indispensable at this stage. Companies often work closely with CDMOs to ensure timely and compliant supply of starting materials during these critical development phases.
Marketed therapeutics are projected to grow at the fastest rate, thanks to the increasing number of regulatory approvals for gene therapy products. As more therapies move from trials to commercial availability, the volume and consistency of required starting materials multiply significantly. Scalable manufacturing becomes vital to meet global demand, prompting suppliers to invest in larger bioreactor systems, automated purification protocols, and enhanced quality control infrastructure.
Oncology remained the dominant application, reflecting the substantial number of gene therapy candidates focused on cancer treatment, especially hematological malignancies. CAR-T therapies and oncolytic viral vectors are among the most prominent applications in this category. These require sophisticated lentiviral or retroviral vectors, specialized plasmids, and cell expansion systems all of which are classified under starting materials.
Genetic diseases represent the fastest growing segment, driven by advances in genome editing and vector targeting capabilities. Conditions such as spinal muscular atrophy (SMA), Duchenne muscular dystrophy, and cystic fibrosis are now being targeted with one-time gene therapies that offer potentially curative outcomes. These programs demand precise and safe starting materials for systemic or localized gene delivery, creating a rapidly growing niche for specialized suppliers.
Biopharmaceutical and pharmaceutical companies dominated the end-use segment, due to their role as primary developers of gene therapies. These organizations either produce starting materials in-house or collaborate with CDMOs to ensure a continuous supply of clinical and commercial-grade inputs. Strategic partnerships, joint ventures, and facility expansions are common in this space to secure material supply chains.
CROs and CMOs are expected to be the fastest growing end-users, as outsourcing becomes the norm in gene therapy development. Many emerging biotech firms prefer to contract out starting material production due to cost and expertise constraints. This trend is fostering the rise of end-to-end CDMO platforms offering plasmid production, vector design, cell line development, and fill-finish services under one roof.
North America remains the dominant market for gene therapy starting materials, largely due to its mature biotechnology ecosystem, robust funding landscape, and favorable regulatory environment. The U.S., in particular, leads in the number of clinical trials and FDA approvals for gene therapies. Companies like Thermo Fisher Scientific, Catalent, and Viralgen have established large-scale vector production and plasmid manufacturing facilities in this region, ensuring material availability and innovation.
Asia Pacific is the fastest growing region, fueled by rising investments in cell and gene therapy infrastructure in countries like China, Japan, and South Korea.
