The Changing Landscape of Single Use in Bioprocessing: An Interview with Stefan Schlack and Jean-Marc Cappia

by

Single use in bioprocessing has changed significantly in recent years. To find out how a leading supplier to the biopharmaceutical industry is redefining its technology to align with new market challenges, science writer, Sue Pearson, had the opportunity to interview Stefan Schlack, Head of Bioprocess Marketing, and Jean-Marc Cappia, Head of Segment Marketing Vaccines, both at Sartorius Stedim Biotech (SSB) in Goettingen, Germany. Redefining Single Use Pearson: Sartorius Stedim Biotech is a recognized leader in single-use technology, and you’ve recently…

Development and Biomanufacturing Strategies for Next-Generation Antibody-Drug Conjugates

by and

The development and manufacture of antibody-drug conjugates (ADCs) requires a series of complex steps. ADC manufacturers must comply with guidelines for both the small-molecule linker-drug and the monoclonal antibody (MAb). The authors describe their company’s development of its lead ADC product. They review process decisions, including the issues that factored into their selection of single-use systems, manufacturing challenges (differences between ADCs and MAbs), and testing methodologies for extractables and leachables. Synthon began as a small-molecule generics company in 1991. During…

Development of a Standardized Extractables Approach for Single-Use Components: General Considerations and Practical Aspects — A Manufacturer’s Perspective

by , , , , , and

The subject of extractables for single-use bioprocess contact materials has been a subject of heated debate since roughly the summer of 2012, when the first ISPE paper was published issuing a call to action to develop a standardized extractables protocol for the industry (1). As a supplier that pioneered the science of extractables (2‒11) and has published extractables data for our products for over 20 years, Sartorius Stedim Biotech (SSB) took the opportunity to look back, take stock, rationalize, and…

Bridging Polymer Science to Biotechnology Applications: A Single-Use Technology Conference Report

by , and

Single-use (SU) technology is used more every year throughout the biotechnology industry. As applications now span from cell banking to drug product, that in turn is raising interest in the interaction of extractables with proteins and cells. The second “Single-Use Technologies†conference organized through Engineering Conference International (ECI) was subtitled “Bridging Polymer Science to Biotechnology Applications†and delved into the science of plastics in bioprocessing applications. On 7–10 May 2017 at the Hotel dos Templários in Tomar, Portugal, people from…

eBook: Scalable Cell-Based Immunotherapy Manufacture: A Comparison of Single-Use Agitated and Static Expansion Technologies

by , and

Early clinical results indicate that personalized autologous immunotherapies could revolutionize cancer treatment (1). However, challenges lie in the realization of cost-driven, scalable cell therapy (CT) manufacturing strategies (2) for generating sufficient therapies to treat a populace, thereby limiting their translation to public health (3). Primary challenges involve complex needle-to-needle logistics, complexities in closed processing, and high variability in starting cell materials that define the autologous nature of such therapies. Despite barriers in industrial-scale manufacture, public health management already has engaged…

Accelerated Development, Manufacturing and Monitoring of Viral Vectors

by

The goals of process intensification are to enhance production while shortening timelines, lessening contamination and environmental risks to products and operators, and reducing operating footprints. Previous publications from Sartorius Stedim Biotech (SSB) have highlighted key elements of such activities. In this report, the authors extend the scope of this discussion to tools and technologies that enable intensification of viral vector manufacturing processes. The first article summarizes presentations from a 2018 seminar for viral vaccine manufacturers. Three guest presentations highlighted the…

Thinking Outside the Bag: Single-Use Technology Can Drive Innovation at the Benchtop Scale

by

Cristy Botens, product manager in bioprocessing, Distek Innovation is important, Botens began, and the focus should be on patients. Every innovation means that medicine gets to patients faster or has fewer side-effects. Recent pharmaceutical innovations include the first new Lupus treatment approved in 50 years, a gene therapy cure for inherited blindness, gene therapies for rare diseases, new chimeric antigen receptors on T cells (CAR-T) clinical trials (over 180 trials now), personalized cell therapy, and a vaccine that prevents cervical…

Capacity Strategies: The Strategies Behind Choosing Between Large-Scale and Single-Use Investments

by

Moderator Dan Stanton, with Weichang Zhou, Jenifer Wheat, Roger Lias, and Jim Vogel Single-use technologies (SUTs) are now prevalent within bioprocessing, but does this spell the end of industry’s historic reliance on stainless steel and fixed facilities? This roundtable was formed to discuss the wealth of investment in single-use (SU) equipment and flexible manufacturing solutions by contract development and manufacturing organizations (CDMOs) over the past few years, pitting that against what looks like a resurgence in fixed-cost stainless steel plants…

Oxygen Mass Transfer Correlation for a Rocking-Motion Bioreactor System

by , and

Disposable bioreactor systems are technologies commonly used in bioprocessing. They provide cost-effective contamination control and allow more flexible facility layouts than do stainless steel alternatives. One of the most popular types of single-use bioreactors uses a rocking platform in place of a traditional shaft and agitator assembly to aerate and mix cell culture material within a presterilized, single-use plastic bag (1). The system studied here is the ReadyToProcess WAVE 25 bioreactor (GE Healthcare Life Sciences). In contrast to conventional stirred…
