Significant Growth Factors

• Accelerating Gene Therapy Approvals and Clinical Pipeline Expansion: The rapid increase in the development and regulatory approval of gene therapies has already produced unprecedented demand on AAV vector production and technologies. As of 2024, 12 AAV-based gene therapies have been approved by the FDA, such as Luxturna, which is used to treat inherited retinal disease, Zolgensma, which is used to treat spinal muscular atrophy and Hemogenix which uses hemophilia B, which has led to an investment in the field. As of 2024, more than 1,200 cell and gene therapy clinical trials were ongoing worldwide, with participants in the AAV-based programs constituting 280 clinical trials (23% of the entire pipeline), according to the Alliance for Regenerative Medicine. In the studies by the American Society of Gene and Cell Therapy, there was a 185% rise in gene therapy trials developing in 2016-2024, the AAV vectors were used in 68% of programs with the desirable safety measure and widespread tissue tropism alongside extended transgene outcome. The FDA has already assigned 78 AAV programs to its Regenerative Medicine Advanced Therapy label, which grants Regulatory assistance with faster track follow-up evaluation. Market analysts forecasted 15-20 more approvals of AAV genes therapies through 2030 with the potential to develop into more driveable good health conditions in millions of cases including Parkinson’s and Alzheimer disease, heart failure and others around the world. To serve every approved treatment, the therapy will need commercial-scale production of 1,000-5,000 doses of the treatment annually in the first year, increasing to 10,000-50,000 doses as the market penetration increases and the treatment indications are expanded. The commercial production need of Zolgensma alone, at a cost of 2.1 million per treatment would require a production capacity of 500-800 patients in the United States annually, which, at therapeutic doses of 2-3 x 1014 vg/kg, would require 1.5-2.4 x 1015 vector genomes annually.

• Rising Prevalence of Genetic and Rare Diseases: The diagnostics and awareness of genetic diseases are on the rise, creating a strong market need due to its unique ability of the AAV gene treatments to treat the underlying genetic defect rather than only controlling the symptoms. The National Organization for Rare Disorders estimates that there are 300 million victims of rare diseases worldwide and 80% of these diseases are genetic and half are experienced during childhood. There are about 7,000 known rare diseases, of which one out of five is approved in the form of FDA treatment and this presents massive unmet medical demand and commercial potential of gene therapy. There is 1 in 10,000 live births of spinal muscular atrophy, and when untreated, Type 1 SMA leads to death or permanent ventilation before the age of 2, which makes the one-time curative treatment offered by Zolgensma a breakthrough at the cost of 2.1 million dollars. Duchenne muscular dystrophy is a disease with an incidence of 1 per 3500-5000 male births, and 20000 new cases are diagnosed each year, and several AAV programs are in Phase 2/3 clinical trials to replace the dystrophin gene. Hemophilia A and B have an estimated worldwide prevalence of 400,000, and AAV-based gene therapy has proven to produce sustained levels of factor eliminating or significantly diminishing bleeding events and factor replacement therapy would cost the patient between USD 300,000-700,000/year. The prevalence of inherited retinal diseases is 1 in 2,000 and Luxturna being approved to treat RPE65-mediated retinal dystrophy opens the way to 15+ more AAV programs to treat blindness caused by different genetic mutations. Rarely occurring genetic diseases impose a cost burden of over 400 billion US dollars each year in the United States alone when the cost of medical care and lost productivity are considered, and gene therapies have the potential to be cost-effective due to the high initial price when it comes to getting rid of lifetime symptomatic treatment.

• Technological Advancements in Manufacturing and Purification: History AAV production has been improved radically by novel production platforms, scalable bioreactor technologies, and downstream purification technologies of AAVs to overcome past bottlenecks in production and allow production of AAVs on a commercial scale to meet increasing demand. Non-particle-based plasmid transfection techniques in adherent cell culture were effective in producing enough plasmid vectors to research scales, which could be 1012-1013 vg/batch, but were not sufficient to achieve all commercial manufacturing goals of 1016-1017 vg/batch. Suspension-adapted HEK293 cells allow growth to greater than 10 x 106 cells/mL in stirred-tank bioreactors, transfection efficiencies of up to 70-85%, and yields of up to 5-15 x 104 vg /cell (10-fold better than adherent systems). Baculovirus expression systems based on insect cells, either Sf9 or High Five cells, offer alternative production systems with a yield of 10^4-105 vg/cell and the simplified purification by the lack of helper virus contamination. Batch-to-batch transfection variability is eliminated by developing stable producer cell lines through various methods, such as CRISPR-mediated site-specific integration, allowing stable large-scale production, although genetic drift and declining productivity over passages are still problematic. New technologies such as downstream purification such as affinity chromatography with AAV-specific antibodies or designed peptides, ion exchange chromatography optimized to separate capsids, and ultracentrifugation with iodixanol gradients have enhanced full -emptycapsid ratios against 30-50%, which is essential to optimizing therapeutic use and reducing immunity to viruses. The improvements of the analytical methods such as droplet digital PCR to determine the genome titer concentration accurately, transmission electron microscopy to measure the capsid structure and mass spectrometry to identify the post-translational modifications ensure the consistency of the product and regulatory compliance.

• Expanding CDMO Capacity and Strategic Partnerships: The growth in the rate of contract development and manufacturing companies focused on AAV production coupled with strategic alliances between the developers of gene therapy and manufacturing support agencies has led to increased progress in programs and spread infrastructure investment. In 2024, the global market of gene therapy CDMO is 3.8 billion USD, and AAV-based services constitute 58% of it as such companies as Catalent, WuXi AppTec, Oxford Biomedica, and FUJIFILM Diosynth open separate AAV production plants. In the 2020-2024 period, Catalent invested up to USD 450 million in AAV manufacturing infrastructure capacity of 50+ programs, both at the clinical and commercial scale, at the facilities in Maryland and Wisconsin. Oxford Biomedica has 750,000 square feet of GMP manufacturing capacity in the UK with 80+ AAV programs capacity at any time and has clients such as Novartis, Biogen, and Sarepta Therapeutics. The transformation of the industry to platform technologies and uniform procedures will allow CDMOs to offer the services to a wide range of clients at a reduced cost of production of per dose of a product of 500,000-1,000,000 USD at the early clinical stage to 50,000-150,000 at larger volumes. Strategic alliances give the developers of gene therapy access to specialized expertise, approved manufacturing platforms, and regulatory exposure without the capital-intensive facility development costs which require investments of up to USD 150-300 million and a time frame of 3-5 years. Three-quarters of the developers of gene therapies are small and mid-sized biotechnology firms that lack the internal capacity to manufacture their programs, and so, CDMO alliances are necessary to enable the progression of their programs to preclinical and commercialization.

What are the Major Advances Changing the AAV Vector Manufacturing Market Today

• Next-Generation AAV Capsid Engineering and Novel Serotypes: The recent techniques of capsid engineering have produced new synthetic AAV serotypes with higher tissue tropism, increased transduction efficiency and lower immunogenicity than natural serotypes, increasing therapeutic use and enhancing manufacturing performance. It has been applied in directed evolution to subject libraries of AAV capsids consisting of 107-109 variants of AAV capsid to repeated selection by target tissues, including neurons, cardiomyocytes, and hepatocytes. Rational design approaches are based on computational modeling and structural biology to alter the surface residues of the capsid, changing their receptor binding specificities, avoiding neutralizing antibodies targeting 40-60% of human populations against typical serotypes, and improving intracellular trafficking. AAV-PHP.eB, a directed evolutionary AAV showing central nervous system delivery but 40-fold greater brain transduction than AAV9 with intravenous injection in preclinical models, has the potential to deliver neurotransduction into the brain noninvasively in a systemic manner to treat neurological diseases previously incurable except by invasive intrathecal or intraparenchymal injection. Computational design of the ancient AAV capsid, Anc80, has a lower pre-existing immunity with neutralizing antibodies being detected in 15% of human serum as compared to 40-67% with AAV2, AAV8 and AAV9, and increases the number of patients who can be treated. The use of engineered capsids shows novel manufacturing benefits because they show better yields in production systems, and some of them produce vectors genome per cell up to 2-5-fold better than wild-type serotypes, directly reducing the cost of manufacturing and timelines. Capsid modification to proteasomal degradation resistance enhances the proportion of infectious particles delivered to the nucleus and leads to higher treatment efficacy and may halve or quarter the amount of required dosage in practice, saving manufacturing costs of USD 25,000-100,000 per patient at commercial scale.

• Scalable Suspension Cell Culture and Continuous Manufacturing: The shift of the planar to suspension culture cell systems and the explosion of continuous manufacturing techniques have changed the scalability, consistency and economic attractiveness of AAV production. Suspension-adapted HEK293 cells are cultured in stirred-tank bioreactors, with a 50 L volume used in clinical material production or a 500-2000 L volume in commercial production, which attain a cell density of 8-12 x 106 cells/mL and do not need the labor-intensive cell factory processes and operations that consume 500-2000 trays per batch. In suspension culture, transient transfection systems that are optimized yield transfection efficiency of 75-90% with polyethylenimine reagents or lipid-based reagents, transfection input of 1-3 ug plasmid DNA/ million cells and yield transfection outputs of 10 4-105 vg/ cell 48-72 hours post transfection. Manufacturers such as Sartorius, Thermo Fisher, and Cytiva also offer single-use bioreactor systems that are not only cleaning-validation-free but also have a lower risk of cross-contamination, as well as the ability to run multiple programs using the same facilities. The implementation of process analytical technology offers real time monitoring of critical quality parameters of dissolved oxygen, pH, glucose, lactate and cell viability, which allows the implementation of closed loop control to ensure optimal production conditions and enhance the yield consistency that was previously 60-75% to 85-95% with a 10% improvement in yield consistency to maintain optimum levels. The current in development continuous manufacturing uses perfusion culture where the cells are kept in the exponential growth stage for long durations, and harvested with a continuous stream of AAV-containing supernatant, this can improve productivity 3-5-fold over batch processes and also can allow the facility to have a smaller footprint than before, as long as 40-60. Economic modelling suggests that continuous manufacturing would decrease the cost of goods from between $75,000-125,000/treatment dose to a $25,000-45,000-dollar treatment dose, which is important to increase access to curative gene treatments.

• Advanced Purification Technologies and Process Intensification: New chromatography media, continuous processing and new modalities of purification have revolutionized AAV recovery, purity and manufacturing throughput as well as cost and timeline reduction. AAV x AAV x AVB Sepharose or POROS Capture Select AAVX affinity chromatography One-step affinity chromatography with AVB Sepharose or POROS Capture Select AAVX yields 85-95% AAV recovery, 1,000-10,000 fold purification of crude lysate, and a low level of empty capsid contamination as opposed to 40-60% recovery and purification of crude lysates in 18-24 hours, with traditional iodixan Multimodal chromatography Multimodal chromatography is a type of chromatographic technique that combines an electrostatic, hydrophobic, and hydrogen bonding interaction to achieve simultaneous removal of the host cell proteins, residual DNA and empty capsids, with full-to-empty ratios improving 50 to 85% and impurities falling below the detection limit of 10 ng/dose and 10 pg/dose, respectively. Size exclusion and ion exchange membrane-based purification has scalability capabilities with processing rates of 100-500 L per hour compared to 10-50 L per hour with packed columns and disposable formats eliminate cleaning validation and campaign changeover is less than 1 day instead of 5-7 days. The buffer exchange, concentration and formulation of closed single-uses can be realized using Tangential flow filtration systems to achieve final concentrations of 1-5 x 1013 vg/mL that are able to be intrathecally administered or administered into the eye via small injection volumes. Process intensification methods combine several unit operations in continuous cycles and content processing time shifts to 3-5 days as opposed to the previous 7-14 days and overall recovery improves to 40-60 as opposed to 20-30.

• Analytical Characterization and Quality Control Innovation: The new generation of analysis technologies with increased sensitivity, accuracy and throughput has revolutionized the characterisation of AAV products to provide detailed quality assessment to support regulatory submissions as well as guarantee batch-to-batch consistency. Droplet digital PCR measures the titer of vectors in genomes with coefficients of variation of less than 5% relative to quantitative PCR with coefficients of variation of up to 15-30%, offering greater accuracy needed when dose-ranging studies are needed and the commercial release of a predecessor technology, where a 10-20% error in titer would result in under- or over-dosing of the test object, which would negatively impact efficacy and safety. Multiwavelength analytical ultracentrifugation is an analysis technique that uses multiple wavelength light to measure full vectorsomes containing capsids, empty capsids with no DNA, and those that are partially filled and offers rich compositional profiles that predict therapeutic potency and immunogenicity profiles in an underlying model. Transmission electron microscopy coupled with automated image analysis analyses 500-1,000 particles per sample in hours (as opposed to days) for statistical measurements of capsid integrity and aggregation and for ratios of full to empty capsids to create manufacturing process optimization decisions. The mass spectrometry of liquid chromatography establishes the characteristics of the capsid proteins that detect post-translational modifications such as phosphorylation, oxidation, and deamidation that influence stability and uptake and immune recognition with sensitivity of detection of the key modifications at 0.1%. Next generation sequencing to validate the integrity of vector genetics (genome), integrase ITR (integrase short SSI) structure, and exclude viral replication-competent AAV sources that affect and interact with the host at detection limits of 1 in 10^6 virus particles, thereby covering protection against potential safety concerns. The high throughput potency assays based on automated microscopy or flow cytometry serve to quantify the transduction efficacy in cell types of interest and thus the data interlinking in vitro results and clinical efficacy; they also report a 3–5-day turnaround compared to traditional assays, which take 7-14 days.
