rAAV has broad application prospects in the field of gene therapy

AAV (Adeno-Associated Virus) is a virus known in the scientific community to infect humans without causing disease. More than 80% of the population carries AAV. Recombinant adeno-associated virus (rAAV) is a genetically engineered vector. The part of its genome that encodes the viral protein is completely deleted and replaced by a therapeutic gene or gene editing tool. Different serotypes show different tropism and immune response profiles, which are suitable for different applications. By adopting suitable AAV serotypes and vector design, precise targeted therapy of different tissues and organs can be achieved. For example, AAV8 preferentially targets the liver, while AAV1 AAV6 and AAV9 have shown the potential to mediate gene transfer in the heart and skeletal muscle, and AAV9 and AAVrh.10 have been proven to be able to cross the blood-brain barrier (BBB) ​​when injected intravenously. rAAV vector is regarded as one of the most promising gene therapy vectors due to its superior safety, long-term stable expression of therapeutic genes, can target most tissues and organs, supports local and systemic injections, etc., and is regarded as one of the most promising gene therapy vectors worldwide. It is widely used in basic scientific research and clinical research.


AAV process and large-scale production challenges urgently need to break through

In 2017, Spark’s AAV gene therapy Luxturna for retinal diseases caused by RPE65 gene defects was approved by the FDA to be listed in advance with a price of 850,000 US dollars. In 2019, Novartis’ AAV gene therapy Zolgensma for spinal muscular atrophy (SMA) was approved by the FDA for the treatment of SMA patients under 2 years of age. As the world’s only one-time SMA approved for marketing, Zolgensma is priced at US$2.125 million and is currently the most expensive drug in the world. The cost of gene therapy on the market is so high because the viral vector technology and large-scale GMP production are extremely difficult, the process is complicated, the production capacity is short, the production cycle is extremely long, and the experienced talents worldwide for large-scale GMP production of AAV is lack, which leads to the monopoly of AAV vector production by gene therapy industry giants. The GMP-level AAV vector production capacity is basically in excess of queuing appointments abroad. The challenges of AAV process and mass production in the next ten years are in urgent need of breakthrough.


PackGene: a one-stop overall solution from vector construction to GMP production

Based on the above-mentioned challenges and opportunities, PackGene utilizes long-term technical experience accumulation and advanced technological innovation advantages, and is committed to solving the problems faced by the gene therapy industry in order to continuously meet the needs of gene therapy for GMP-grade AAV vector technology and scale, effectively integrate talents and facility resources, improve process development and large-scale production efficiency. In October 2020, PackGene officially announced that its industry-leading “disposable technology” cGMP AAV production base of 1500 m2 was put into full production.

The base is in the Ledy Innovative Science and Technology Park, Science City, Guangzhou Economic and Technological Development Zone, China. It is also an industrial base dedicated to the large-scale GMP production of AAV vectors. It is equipped with world-leading large-scale production facilities and systems. It will meet the urgently need of customers in cooperation for high-quality clinical-grade AAV samples, which will be used in IND declarations, Phase I-II clinical and IIT trials. The completion and full production of the base is an important milestone for PackGene to make good progress in gene therapy CDMO platform construction, GMP team building and clinical-level AAV project implementation.


PackGene GMP production base: the use of disposable technology

The AAV vector’s independent factory officially completed this time by PackGene adopts a large number of leading “Single-use Technology” in accordance with the requirements of GMP construction specifications, with a total construction area of 1500 m2. According to the concept of quality by design (QbD), the clean environment is in accordance with the C+A design standard, and physical isolation is used to strictly separate the different functional workshops. The GMP production area is only used for the GMP production of AAV vectors, effectively avoiding the limitations which shared with CDMO platforms previously.

The GMP base will be equipped with the world’s leading iCellis500 adherence production system (up to 500m2 adherence area) and Xcellerex XDR MO suspension production system. The downstream is equipped with ÄKTA purification system and its chromatography purification process. Various process routes have been established and realized the optimization of the GMP platform process. At present, the output can currently achieve a single batch of 1E+16-17GC or vg AAV production. The three batches of AAV production for the GMP application for IND declaration can be shortened to 1-2 months.

The production and quality control of gene therapy products implemented in the GMP workshop of PackGene are all AAV vectors, and the layout design is optimized according to the optimized process route of PackGene, which greatly improves the space utilization rate and greatly reduces the cost of cleaning and verification and avoids cross-contamination of gene therapy products in the large-scale production process, to meet the requirements of IND or IIT production or registration of gene therapy products.

In addition, PackGene has also explored core process technology routes that can greatly increase single-batch output and reduce input costs, gaining more valuable speed advantages for customers, and helping to speed up the registration of gene therapy products and the production of clinical-level samples.

The GMP AAV production base of PackGene’s full-scale production is equipped with complete hardware and software facilities and GMP management system to ensure the sterility, purity and safety of AAV-based gene therapy products in the production process, and comply with GMP standards. Achieve the reproducibility, reliability and scalability of the production process.
