Improving titer, quality, and efficiency of AAV manufacturing and production by optimizing osmolality

4 Jul 2022

The use of viral vectors is now a common approach within Cell and Gene Therapy, but there are still difficulties when scaling up for bioprocessing. This study, presented by Advanced Instruments and undertaken by Cell and Gene Therapy Catapult, provides preliminary evidence for impact on overall yield, and quality of the adeno-associated virus 1 (AAV) due to a timed osmolality shift with and without a feeding step.

Sample ManagementSample management systems include sample storage devices such as freezers and plate storers, sample environment enclosures and sample organization, retrieval and sorter systems. Useful system features include high-throughput, automation, robotic arms, automated liquid handling and associated database systems. Accessories in sample management include barcode scanners, heat sealers and tubes.RegulatoryPharmaceutical regulations impact on all areas of drug development, manufacture and control and supply. Services are provided from the early stages of drug development and clinical trials through to dossier submission, approval and marketing. Regulatory also includes submission of analytical studies from the pharmaceutical product and safety. Scale-upScale-Up is generally defined as the process of transferring the results of the discovery phases of the drug discovery process, obtained on a laboratory scale, to the pilot plant and finally to production scale. Scale-Up uses reactors and pump systems as well as reagents, standards and buffers. Often Scale-Up is provided as a service by Contract Manufacturing Organizations (CMOs). Bioprocessing / FermentationBioprocessing is the use of biological materials to perform commercial, scientific or medical research processes. Biological materials used include cells, enzymes and organisms. Usually bioprocessing requires a batch or continuous bioreactor such as a fermentor or cell culture system. The advantages of using a reactor include high productivity, easy configuration, adjustable values and automation.OsmometryIn osmometry, the osmotic strength of a solution, colloid or compound is measured. Osmotic strength is a measurement of the total concentration (distinct from molarity) of dissolved material in solution. This technique is often used for the determination of average molecular weight.Cell TherapyCell therapy involves using living cells to treat diseases, often by replacing damaged cells or stimulating regeneration. Stem cell therapy and CAR-T cell therapy are examples of cutting-edge treatments in regenerative medicine and cancer immunotherapy.

The most well-known example of a biotherapeutic product, and the first to be approved for therapeutic use, was recombinant human insulin.Gene TherapyGene therapy is a technique that modifies or replaces genes within an individual's cells to treat or prevent diseases. This approach holds potential for curing genetic disorders, cancers, and certain viral infections. Advances in gene editing technologies like CRISPR are driving the growth of gene therapy.
