Dye Ingress Methods for Container–Closure Integrity Testing: An Industry Position Paper

The primary goal of container–closure integrity (CCI) is to maintain the sterility and product quality of parenteral biopharmaceuticals throughout their shelf life and use. Guidelines detailing the initial CCI qualification and validation requirements have been defined and can be found in the US Pharmacopeia chapter 1207 (USP<1207>) (1). The guidelines described in USP<1207> can be applied to any common CCI testing (CCIT) method to achieve a method suited for its intended use within a drug product lifecycle. CCI is not…

Worldwide Biopharmaceutical Manufacturing Capacity Analysis: Growth Continues Across the Board

While the growth in biopharmaceutical manufacturing capacity in developed, major market countries is continuing its slow and steady climb, developing regions often are seeing double that growth rate. Over the past eight years, as detailed in the “About the Data” box, our company’s index of the top 1,000 biomanufacturing facilities (1) has tracked and ranked bioprocessing facilities worldwide in terms of known or estimated bioprocessing capacity (cumulative onsite bioreactor volume) number of biological products manufactured at clinical scale commercial scale…

Big Biotech Data: Implementing Large-Scale Data Processing and Analysis for Bioprocessing

Managing large amounts of data presents biopharmaceutical companies of all sizes with the need to adopt more efficient ways to handle the ongoing influx of information. At KNect365’s September 2017 Cell and Gene Therapy conference in Boston, Lisa Graham (founder and chief executive officer of Alkemy Innovation, Inc. in Bend, OR) spoke about the need for data management, data analysis, and process monitoring systems to evolve. Although she was speaking at a cell therapy event, her points are applicable to…

Cell-Culture–Based Influenza Vaccine Manufacturing: Evaluation of Near-Infrared Spectroscopy for In-Line Determination of Virus Titers

Each year, over 20% of the human population is infected with the influenza virus, resulting in 250,000–500,000 related deaths globally and ~38,000 deaths in the United States alone. Of further concern is the potential for pandemic outbreaks, which pose a severe worldwide threat to public health (1, 2). Vaccination has proven to be a critical tool for controlling the spread of infectious diseases, as evidenced by the eradication of polio, smallpox, and diphtheria in most parts of the world. Influenza…

Virus Segregation During Purification Processes: Calculation of Critical Potential Carryover of Viruses

Before a pharmaceutical product is introduced into humans, either in a clinical trial or as a marketed product, virus safety must be evaluated carefully. Virus safety normally is ensured using a three step complementary approach: selecting and testing cell lines and/or raw materials for the absence of viruses, testing the product at appropriate steps of production, and assessing the capacity of a production process to clear infectious viruses (1). The latter (also referred to as viral clearance) is the subject herein. Spiking studies are conducted to evaluate the capacity of a purification…

A UF–DF Screening System for Bioprocess Development: Efficient and Cost-Effective Process Fit and Scale-Up to Manufacturing

Ultrafiltration and diafiltration (UF–DF) of therapeutic proteins are performed in either tangential or crossflow mode using membrane filters. UF–DF plays a critical role in both downstream and upstream processes for the biopharmaceutical industry (1). In upstream production processes, classical tangential-flow filtration (TFF) or alternating tangential-flow (ATF) systems are used in high–cell-density perfusion for protein expression by cell culture (2). TFF is used in downstream processing for UF–DF and concentration of therapeutic proteins. TFF unit operations are common in protein purification…

The Effect of Albumin on Viability in Stem Cell Therapy

Stem cell therapies are some of the most cutting-edge and sophisticated therapeutic developments. They offer an attractive alternative approach to more widely used treatments for conditions such as multiple sclerosis, metabolic diseases, cardiovascular disease, liver disease, and cancer. But developers still face challenges, some of which can be addressed by the use of recombinant human albumin. As a long-established ingredient of cell culture media, albumin is well recognized for its ability to facilitate growth of many cell types. The industry is expanding its use of high-quality, fully recombinant, current good manufacturing practice…

In-Line Turbidity Sensors for Monitoring Process Streams in Continuous Countercurrent Tangential Chromatography (CCTC)

A strong connection between turbidity and total suspended solids (TSS) has been linked in the past to measuring well defined particles in processes. Optical density probes have seen wide adoption in the biotechnology industry for monitoring cell growth within a bioreactor, whereas in-line turbidity sensors have been used to monitor filter performance. Turbidity measurements offer a rapid quantification of suspended solids but have not been used in the biotechnology industry for chromatographic resins. In this study, turbidity measured with equipment developed by PendoTECH was used with novel continuous chromatography technology developed by Chromatan…

Single-Use Bioreactors: Performance and Usability Considerations, Part 2

As the biopharmaceutical industry continues toward streamlined bioprocessing and intensified cell-culture biology, selection criteria of single-use bioreactors (S.U.B.s) and other bioprocessing technologies will become increasingly rigorous, emphasizing the importance of considering every aspect of technologies under evaluation. In part 1, we discussed performance for process control, including the maintenance of critical process parameters (CPPs), and highlighted bioreactor performance (e.g., mass transfer, power per volume, and temperature control) as a critical consideration during the selection of S.U.B.s (1). Part 2 focuses…

Designing Laboratories for Flexibility and Collaboration

The blockbuster business model may have paid off in the past, but tomorrow’s biopharmaceutical successes will depend more on rapid and diverse discovery than on any single breakthrough. In the race to get new therapies from research and development (R&D) into pharmacies, next-generation laboratory space could become a game-changer. Blockbuster drugs typically were made in industrial laboratories — and industrial-strength measures were required to reconfigure those spaces as new research priorities emerged over time. Facing changing patient needs and ongoing…
