Manufacturing a Recombinant Retrovirus: Downstream Purification Process Development through GMP Implementation

This webcast features: Mark Fitchmun, President and CEO, Somatek, Inc. Purification of enveloped viruses and virus-like particles presents several challenges due to their large size and complexity. In this webinar, a case study will be presented and will detail the importance of resin screening, endonuclease treatment, process development, and the scale-up purification of a retrovirus-like particle intended for use in human subjects. The resulting current good manufacturing practice (CGMP) compatible process required approximately four hours to purify 240 L of…

Crude Sample Analysis in Process Development: Time and Cost Savings

by BPI Contributor

This overview highlights a few examples from drug discovery and process development where the Octet® system demonstrated a significant reduction in the analysis time over ELISA and HPLC by eliminating the need for purification, while still achieving high accuracy and precision. The total assay times were dramatically reduced with fewer assay steps and less labor time involved. The easy and versatile, fully integrated Octet® assay has additional advantages over other label-free technologies like SPR, where sample washing steps are required.…

Bursting the bubble: COVID-19 and the gene therapy skills base

by Tony Hitchcock - Technical Director, Cobra Biologics

Despite various global lockdowns during the ongoing COVID-19 pandemic, the development of gene therapy products is on a significant upward curve with record fundraising in 2020. However, manufacturing is an increasing bottleneck in realizing the full potential of many DNA and viral vector facilities, and COVID vaccine production will have undoubtedly exposed this shortfall in production capacity. Such a deficit was and is being addressed on one level by significant investment in production facilities, and secondly by the development of…

Increase Efficiency in Your Manufacturing With the Right Buffer Management Strategy

by BPI Contributor

This webcast features: Jenny Dunker, Global Product Manager, and Alex Troken, Global Product Manager, Cytiva Buffer preparation is still a highly manual activity in the biopharmaceutical industry that often requires a lot of resources due to the large number and overall volume of buffers and process liquids used in a typical bioprocess workflow. Most companies are still relying on the traditional ways of preparing buffers, but there are more modern, alternative buffer preparation methods that can bring significant savings and…

Formulation and Characterization Strategies for Gene Therapies

by BPI Contributor

This webcast features: Sarathi Vijay Boddapati, PhD, Associate Director, Formulation and Drug Product Development, Catalent Cell and Gene Therapy Formulation studies for gene therapy products are currently limited in scope and revolve around gathering stability data at frozen storage conditions. A systematic approach towards understanding degradation mechanisms followed by buffer and excipient selection is required. Catalent Cell & Gene Therapy is working towards an approach for gathering product knowledge and establishing formulation selection criteria using traditional/routine techniques that are historically…

How to Improve the Capturing of Antibody Fragments

by Jonas Wege and Romain Dabre

Some of the latest promising biopharmaceutical drug substances are antibody fragments. Antibody fragments are either separate functional subunits of antibodies or recombinant molecules, which, just like antibodies, are composed of immunoglobulin domains. These drugs offer several therapeutic advantages over conventional monoclonal antibodies. Upstream processing for antibody fragments is easier than it is for standard antibodies. Recombinant-based antibody fragments can be modified to meet specific needs of affinity, avidity, valence, and action mode. They also can be produced in prokaryotic cells…

HCP Analysis using Mass Spectrometry: Strategies for Your Process Development Toolkit

by BPI Contributor

This webcast features: Dr. Christina Morris, Senior Scientist, BioPharmaSpec Expression systems of either mammalian, yeast, or bacterial origin are commonly used as host cells for the production of biopharmaceuticals. As a consequence of using these systems, endogenous host cell proteins (HCPs) will inevitably copurify or will be coexpressed and contaminate the product material. It is a regulatory requirement to identify and monitor process-related impurities such as HCPs, and a qualitative and quantitative assessment of the components in the final drug…

Understanding Viral Clearance During Anion Exchange Chromatography by Using a Novel Design of Experiment Approach

by BPI Contributor

This webcast features: Moira Lynch, Innovation Leader, Purification and Pharma Analytics, Thermo Fisher Scientific, and Zhijun (George) Tan, Associate Scientific Director, Bristol Myers Squibb Demonstrating viral clearance of a downstream process is a requirement for drug candidates such as monoclonal antibodies (mAbs) that proceed to phased clinical trials. Due to the specialized nature of viral clearance studies, these studies are often outsourced to dedicated companies, making this a costly process. This expense pushes these studies off until absolutely necessary and…

High-Quality and Cost-Effective Plasmid Platform
