Cambridge Healthtech Institute ’s Inaugural

Gene Therapy CMC and Manufacturing

20-21 March 2019


The vector-based gene therapy industry has undergone rapid advances over the last twelve months and shows no sign of slowing down. The clinical results are beyond encouraging. However, the pressure is now on CMC, analytical, process development and manufacturing department to produce these therapies at scale.  

The Gene Therapy CMC and Bioproduction conference examines the practical challenges facing the production, characterization and quality control of vector-based gene therapies, with dedicated sessions on AAV and lentivirus-based platforms as well as oncolytic viruses, CRISPR and other gene editing therapies. Topics include new and emerging analytical strategies, upcoming regulations and the latest manufacturing strategies for large- and small-scale production.

14:15 Viral Vector Manufacturing and Control: Regulatory Considerations and Challenges

Matthias_RennerMatthias Renner, PhD, Scientist, Federal Institute for Vaccines and Biomedicines, Paul Ehrlich Institute

In respect to manufacturing and quality control, viral vectors are considered to be one of the most complex medicinal products. Regulatory aspects considering the fundamental steps in manufacturing and control of these medicinal products will be presented, and the regulatory framework for these products which are classified in the EU as advanced therapy medicinal products and are regulated centrally by the European Commission and the European Medicines Agency will be given.

14:45 Understanding the Effect of Post-Translational Modifications of AAV Capsid Proteins and their Impact on AAV Infectivity

Liu_LinLin Liu, PhD, Principal Scientist, Bioanalytics Characterization, Biologics Development, Sanofi

Viral capsid proteins play an important role in cellular targeting and trafficking as part of the viral infection cycle, and thus any changes in the viral capsid protein sequence or post-translational modifications (PTMs) might impact viral targeting and infectivity. We evaluated the role of AAV capsid protein PTMs on AAV transduction potential by generating AAV2 and AAV5 capsid mutants and performing a stress study. 

15:15 Analysis of Purity and Packaging of Gene Therapy Vectors and VLPs to Support Process Development Decisions

Vanessa Carvalho, Senior Scientist, Electron Microscopy Services, Vironova

Challenges with scale up of gene therapy processes include surprises in purity profiles. Robust analytical solutions are required to avoid late surprises. Transmission electron microscopy (TEM) provide unmatched insights in characterization of viral gene vectors. MiniTEM automatically provides: comparative metrics on purity profiles of viral particle samples; automatically differentiates intact viral particles from process related impurities; correlation between potency and viral particle morphology.


15:45 Refreshment Break in the Exhibit Hall with Poster Viewing

16:25 Analytical Approaches to Characterize AAV Gene Therapy Products

Christine_LeBecChristine Le Bec, PhD, Head, CMC Analytical, Technology Development, Genethon

In recent years, AAV vectors have been increasingly evaluated in various gene therapy clinical trials. To sustain this, reliable, fast, robust, GMP compliant analytical methods and characterization protocols are needed. Specific analytical assays were performed to assess vector productivity, vector purity, potency and safety. I will present different methods to quantify host cell DNA and host cell protein to support the process development and characterize preclinical and clinical lots.

16:55 Looking at the AAV Particles from Inside and Outside Using Novel Analytical Tools

Eduard_AyusoEduard Ayuso, DVM, PhD, Team Leader, Innovative Vectorology; Scientific Director Translational Vector Core (CPV), Translational Gene Therapy for Genetic Disorders, Inserm, University of Nantes

Our laboratory has been deeply involved in the harmonization of adeno-associated viral vector (AAV) characterization through the international reference standard efforts and has developed novel protocols for accurate titration of these vectors. Moreover, recent analytical tools based on next generation sequencing technologies, allowed us to identify and quantify residual DNA species in vectors produced in mammalian and insect cells. More recently, we have detected the presence of miRNA in the final product (i.e. after purification) of AAV vectors. Our examples show that it is crucial to push vector analytics forward to drive innovation in manufacturing processes and vector design.

17:25 The Removal of Virus Related Impurities in Pilot and Manufacturing Scale by Large Scale Ultracentrifugation

Kraus_BarbaraBarbara Kraus, PhD, Director, Gene Therapy Process Development, Takeda

The Gene Therapy Center Austria (GTCA) is a CDMO with extensive late stage development & commercialization expertise, including Phase III and commercial manufacturing capabilities. Our AAV platform is available for internal programs as well as for external partners. This presentation will reveal how efficient and robust the large scale ultracentrifugation removes virus related impurities and thus mainly contributes to high quality gene therapy products for patients with rare diseases.

11:15 Process Development Challenges in Gene Therapy Moving from Early Clinical to Late Phase/Commercial

Tarik_SenussiTarik Senussi, Head, Process Development, Gyroscope Therapeutics

Material to supply initial clinical studies is often delivered via early stage contract manufacturing organisations to clinical phase appropriate regulatory standards. This inevitably requires subsequent modification and transfer to a facility that can support late stage and commercial manufacture as the product progresses through development. This talk will cover the opportunities and challenges associated with this transition, considering robustness, yield and comparability.

11:45 Vector Design and Production Scale-Up of AAV- Based Gene Therapies for Inflammatory Disease

Janneke_MeulenbergJanneke Meulenberg, PhD, MBA, COO, Arthrogen

Arthrogen is developing local gene therapy for inflammatory diseases, using viral mediated gene transfer. Arthrogen’s first product that has been tested in clinical trials, is an AAV5 based vector expressing interferon beta from an inflammation inducible promoter. This vector was produced using classical plasmid transfection in adherent cells. Arthrogen is currently evaluating different scalable systems for future AAV production runs. The pros and cons of these systems and the consequences for product characterization and quality control will be discussed.

12:15 Lentiviral Vector Manufacturing - Problem or Not?

Hanna_LeschHanna Lesch, PhD, Director, Gene Therapy Unit, Kuopio Center for Gene and Cell Therapy

There are very few lentivirus success stories. Partially that has been explained because of the manufacturing issues. Is it still today a problem or are there solutions available? The talk will cover the main challenges, case study of process development and scale-up of lentivirus manufacturing into iCELLis500 and will dive into the future visions and possibilities.

13:50 Bioprocessing Strategies for Gene Therapies

Mercedes-SeguraMercedes Segura, PhD, Director, Next Generation Platforms and Technologies, bluebird bio

Current viral vector manufacturing processes are inefficient and scale-limited, which ultimately results in insufficient manufacturing capacity and high cost. In particular, lentiviral vectors are produced at low yields for short periods of time and are unstable under standard processing conditions. The challenges and opportunities with lentiviral vector production platforms will be discussed.

14:20 Lentipro Stable Producer Cells for the Development of Scalable Lentiviral Vector Manufacturing

Ana_Sofia_CoroadinhaAna Sofia Coroadinha, PhD, Lab Head, Health & Pharma Division, Animal Cell Technology Unit Cell Line Development and Molecular Biotechnology Lab, IBET

This work discusses the challenges in lentiviral vector manufacture and scale-up as well the strategies and novel technologies to be adopted to enable effective upstream processes. At upstream, many of the challenges are related to the vector cytotoxicity, restricting the bioreaction to short-term productions. Thus, one of our strategies is to reduce vector cytotoxicity which enabled to establish lentiviral vector producer cell lines constitutively producing infective virus over 1 week.
