Cell and Gene Therapies Get a Reality Check: A Conversation with Anthony Davies of Dark Horse Consulting Group

As founder of cell and gene therapy (CGT) specialist firm Dark Horse Consulting Group in California, Anthony Davies speaks from a quarter century of experience including former positions at Onyx Pharmaceuticals, Syrrx, ZymeQuest, Serologicals, Geron Corporation, Capricor, and 4D Molecular Therapeutics — and he currently serves on the board of directors for TrakCel and the scientific advisory boards for Akron Biotech and BioLife Solutions. In his plenary address at the Phacilitate 2020 Leaders World conference (part of Advanced Therapies Week…

Quality By Design for Advanced Therapies: An Informed Route to Enhanced Late-Stage Clinical Success and Empowered Process Flexibility

As advanced therapies, including regenerative medicines, progress toward commercialization and market approval, early warnings from key opinion leaders (1, 2) regarding the importance of better understanding quality target product profiles (QTPPs) and critical quality attributes (CQAs) of such products have resounded ever louder (see the “Terminology” box for definitions). Costly late-stage delays, redirections, and even abandonment of clinical programs can be linked to quality issues associated with inadequate understanding of process and product. Therefore, a review of the benefits of…

Transforming Personalized Medicine into Off-the-Shelf Cell Therapies

Initial progress in cell and gene therapy has seen 12 advanced therapeutic medicinal products (ATMPs) become available on the market in 2019 for a range of conditions, from monogenic diseases to cancer. Despite such progress, development of clinically and commercially successful cell therapies presents manufacturability challenges and questions about bypassing patients’ immune systems. The availability of rapid sequencing and next-generation bioinformatics has made it possible to understand the mechanisms of disease better and accelerate development of therapeutic responses. The same…

Sharing Viral Vector Expertise: A Conversation with Yposkesi’s Chief Executive Officer

As a full-service contract development and manufacturing organization (CDMO) specializing in gene therapy development, Yposkesi produces recombinant adenoassociated virus (AAV) and lentivirus (LV) vectors using adherent-based and suspension-adapted cell expression platforms. Alain Lamproye joined the company as chief executive officer (CEO) in January 2017, having served previously as president of the biopharmaceutical business unit of Novasep (2012–2017) and as CEO of Henogen, its subsidiary dedicated to gene therapy. He has held managerial positions in pharmaceutical operations at Merck Serono (including…

Ask the Expert: Key Considerations for Cryogenic Preservation and T-Cell Viability

Cryopreservation provides critical protection for cell therapies by minimizing genetic changes. But cooling too slowly or quickly risks diminishing cell viability upon thaw. On 11 March 2020, Peter Kilbride (senior research scientist) and Julie Meneghel (cryobiologist), both of Cytiva (formerly GE Healthcare Life Sciences), discussed the importance of controlled-rate cryopreservation. Illustrating how mammalian cells change when frozen, Kilbride and Meneghel offered concrete cryopreservation strategies and identified temperatures at which it is safe to stop controlled cooling and transfer drug product…

Industrialize Your Viral Vector Production in Adherent and Suspension Cell Cultures: Know the Pros and Cons

This educational podcast, “The Evolution of Culture Systems for Viral Vector Production: Advantages, Challenges and Cost Considerations,” recently published by Cell and Gene Therapy Insights, discusses in detail the pros and cons of viral vector production in adherent and suspension cell culture. This special report illustrates how Pall Biotech’s iCELLis 500+ bioreactors and Allegro STR bioreactors can bolster adherent and suspension culture, respectively, for viral vector production. Fill out the form below to read the complete report and learn more now.…

Bioprocessing 4.0 Accelerates Biological Research and Development Using Computer-Aided Biology

Computer-aided biology describes a growing ecosystem of tools that augment human capabilities in the laboratory. In this report we give two case study examples of how computer-aided biology has transformed industrial gene therapy bioprocessing. Read on to discover how Synthace’s Antha cloud-based software platform has enabled industrial collaborators Oxford Biomedica and the Cell and Gene Therapy Catapult to harness the power of Bioprocessing 4.0 by: incorporating new process analytical technologies (PAT), such as Raman Spectroscopy, into their unit operations automating…

Discussions at Phacilitate 2020 on Business, Manufacturing, and Future Trends

Presenters in the three main program tracks at the Phacilitate Leaders World conference in Miami, FL, this past January represented sponsor-developers of cell/gene-therapy (CGT) products, contract service providers, and technology suppliers to the industry. Topics include process and product development strategies for advanced therapies, regulatory and inspector expectations, automation and closed-system processing, the choice between in-house and outsourced manufacturing, quality assurance and control, analytical methods, viral vectors, and artificial intelligence and Industry 4.0. At the end of each session, presenters…

The Technology of Tomorrow — Today

Sponsored by BioProcess International and its sister publication BioProcess Insider, the “Tech of Tomorrow Zone” at Phacilitate 2020 played host to a number of companies showcasing platforms and ideas that they believe can revolutionize cell and gene therapy (CGT) manufacturing. Some common themes arose in this diverse zone, highlighting technologies from stem-cell supply solutions to viral-vector filling. Participating companies are aware of the complexities involved in producing regenerative medicines, and each proposed solution was intended to reduce the burden on…

Scalable Manufacturing of Lentiviral Gene Therapies

Lysosomal storage diseases are caused by mutated genes that express defective lysosomal proteins, such as essential enzymes. For example, cystinosis is a metabolic disease caused by a defective gene that encodes cystinosin, an exporter protein (Figure 1). Avrobio develops gene therapies to treat lysosomal storage diseases. On 8 October 2019, the company announced that its first patient had been dosed in the AVR-RD-04 investigational gene therapy program, which involves genetic modification of the patient’s own hematopoietic stem cells to treat cystinosis.…
