eBook: Single-Use Technologies: Accelerating Bioprocess Design with Key Insights from the Experts

Companies turn more and more to single-use technologies (SUTs) to mitigate production challenges — and with good reason. SUTs clearly decrease conventional costs while increasing process integrity. Yet as the writers in this compilation suggest, SUTs are now making possible new, exciting ways to configure, operate, and evaluate biomanufacturing. In this compilation, BioProcess International gathers key insights from biopharmaceutical industry experts at Sartorius Stedim Biotech to explore how SUTs can realize high-quality yet cost-effective end-to-end bioprocessing. The studies herein identify…

eBook: Automation: The Value of Plug-and-Play Automation in Single-Use Technology

The biopharmaceutical industry’s movement away from large-scale, fixed-tank facilities to flexible facilities featuring single-use technologies (SUTs) has demonstrated the value of modular equipment and agile process design. SUTs have proven to be clear advantages to end users because those technologies enable quick facility build and changeover times. But linking SUT equipment with equally flexible automative technology has been difficult. Herein a group of automation experts from the BioPhorum Operations Group (BPOG) elaborate “plug-and-play” principles and introduce a supervisory control system…

From Supplying Components to Providing Total Solutions: Overviewing Supplier Side Capabilities

Only a thin line now separates biopharmaceutical manufacturers and suppliers because the latter are increasingly becoming the process knowledge owners in the biopharmaceutical industry. As a result, suppliers are racing to become the most efficient “total solutions” provider. In the 1990s, leading players in the industry such as Pall, Millipore, and Sartorius all supplied membrane filters for upstream and, to some extent, downstream processes with their crossflow and final filtration offerings. Pharmacia (which became GE Healthcare) was the major force…

Bioprinting Capabilities and Futures

Bioprinting has advanced rapidly through engineering step changes in the use of three-dimensional (3D) printing. With these developments, living cells can be positioned layer by layer to produce functional tissue structures. Key attributes of this emerging technology are its high scalability and modularity, which enable automated and repeatable manufacture of a wide variety of tissues. These high-throughput biofabrication capabilities equip companies with tools to develop 3D-printed tissues for broad applications, from in vitro drug testing models to therapeutic tissue implants,…

The First Quantitative Industry Assessment of Single-Use System (SUS) Reliability: Raising the Bar for BPSA’s Value to Industry

Over the past 24 months, the leadership of the Bio-Process Systems Alliance (BPSA) has initiated a pilot program to demonstrate the joint feasibility of collecting and sharing pertinent industry business data. We began with “quality-complaint data” centered on the premise that product complaints are tightly associated with product-quality defects in single-use systems (SUSs). This approach can be viewed as “risk assessment 101.” BPSA’s Representation of the Single-Use Industry BPSA is an industry organization primarily comprising drug manufacturers, single-use system suppliers,…

Adenovirus Downstream Process Intensification: Implementation of a Membrane Adsorber

Historically, companies developing vaccines have used attenuated pathogens, inactivated infectious agents, or antigenic constituents purified from pathogenic sources. In the past 20 years, technological advances such as recombination and viral vectors, have enabled development of vaccines against diseases with previously no available treatments (1). Viral vectors have become one of the most rapidly evolving and promising fields in vaccinology and regenerative medicine. In addition to preventing infectious disease, they have a broad range of potential applications, including treatment of hereditary…

The Critical Role of Media in Intensified Upstream Processes

As the need for novel therapeutics increases, so does pressure on the biopharmaceutical industry to improve productivity, accelerate development, increase, and reduce costs — all while ensuring drug product quality. Upstream intensification strategies such as perfusion culture can address those challenges and achieve higher protein titers that can translate into higher throughput, improved flexibility, and compressed timelines. Successful implementation of perfusion culture or the transition to perfusion from fed-batch culture requires a different and strategic approach to media selection, not…

Forward Thinking — Evolving the Cell and Gene Therapy Industry: Modern CAR T-Cell Process Addresses Future Demand

It is an exciting time to be involved in the cell and gene therapy industry. We have come to a tipping point where we have shown that the science works. Now we need to industrialize and standardize it, so we can get these life-saving therapies to more patients. As an industry, we can learn from all the experience in the biologics space. With monoclonal antibodies (MAbs), we have transitioned from a manual process to a more standardized and automated set-up.…

Production of Transient Lentiviral Vectors in HEK 293T Cells: Cultivation on Fibra-Cel Disks in a Single-Use, Packed-Bed, Stirred-Tank Bioreactor

Although demand for lentiviral vectors (LVs) for cell and gene therapy is increasing, the standard two-dimensional culture systems used to produce LVs present significant disadvantages. Current bottlenecks in LV production are caused mainly by such disadvantages. Switching to use of bioreactors can eliminate those problems because bioreactors offer the benefits of process automation, tight regulation of production conditions, and reduced labor input. The study reported herein was carried out by the group of David Parsons at the University of Adelaide.…

Single-Use Tubing Systems: Confidence Through Validation

Single-use systems (SUSs) are becoming increasingly common in bioprocessing operations because of their low capital requirements and validation costs. As this trend continues to develop, pharmaceutical manufacturers are asking SUS manufacturers to provide assurance that their products comply with current good manufacturing practices (CGMPs) and do not alter drug products by exceeding established operating ranges. Certification of product cleanliness has become common for manufacturers of final packaging components such as vials and stoppers, but rarely are tubing products certified to…
