Early Stage Analytical Considerations for Late Stage Biologics Success

This BPI Special Report will cover phase appropriate analytical strategies that will balance various drivers to meet overall development goals without sacrificing the requirements of a program. The goal is to provide important recommendations for analytical method development that can help the biopharmaceutical industry identify opportunities to improve lead time and reduce development costs while maintaining required quality standards. Fill out the form below to learn more about analytical method development now.   Arugadoss Devakumar, PhD, is director of analytical…

The Analytical Perspective: Turning Data Into Information Requires Teamwork

As head of bioanalytics at Sanofi, Claire Davies leads a team of >90 people involved in development, qualification, and transfer of methods to internal and external commercial quality control units; characterization, comparability, and developability of proteins and gene therapies; and analytical support for up- and downstream development, production, product release, and stability testing. She has served in a number of roles over 18 years with Sanofi, from chemistry, manufacturing, and controls (CMC) leadership of preclinical to commercial products (leading and…

Trends in COVID-19 Diagnostic Test Development

The ongoing coronavirus disease 2019 (COVID-19) outbreak caused by a novel coronavirus (SARS-CoV-2) is posing a great threat to global public health and economies. Accurate and rapid detection of the SARS-CoV-2 virus and diagnosis of infection status will play a critical role in understanding the disease, selecting appropriate treatments, controlling the spread, and developing informed back-to-work policies. Currently, a review of ongoing efforts in the development of COVID-19 diagnostic tests is lacking. For this review, we collected data on more…

Fluorescent Nanosensors: Real-Time Biochemical Measurement for Cell and Gene Therapies

Cell and gene therapies are destined to transform the methods by which global healthcare challenges are approached and overcome (1). The US Food and Drug Administration is reviewing and approving an increasing number of cell and gene therapy products (2), and biopharmaceutical developers are dedicating immense resources to realizing the enormous potential of these therapeutics. Therefore, technologies that facilitate their effective and efficient manufacture will accelerate cell and gene therapies’ transition from medicines of the future to medicines of the…

Soft Sensors for Bioprocess Monitoring

Achieving the high process efficiencies and optimization of Manufacturing 4.0 will require sophisticated software systems, mathematical modeling, and on-line process monitoring. Soft sensors are valuable tools that enable users to measure process parameters in real time. I spoke with Benjamin Bayer, data scientist at Novasign GmbH and doctoral candidate at the University of Natural Resources and Life Sciences in Vienna, Austria, about the potential of soft sensors for bioprocessing and important considerations for their use. Introduction How would you describe…

Are You Missing the Bigger Picture with Your AAV Analytics? Fast, Low-Volume Subvisible Particle Analysis for Characterizing Viral Vectors

Subvisible particle (SVP) analysis is a key indicator of stability and safety and is an essential parenteral drug quality metric. Yet assessment of SVPs is especially challenging in adenoassociated virus (AAV) vector formulations, in which limited precious sample is available. Traditional SVP methods consume large sample volumes, while dynamic light scattering (DLS), size-exclusion chromatography (SEC), and visual inspection can miss aggregates in the subvisible range entirely. This special report introduces backgrounded membrane imaging (BMI) technology as a solution for detection…

eBook: Development of Bioassays — A Report from the BEBPA’s First Virtual Meeting

Bioassay development is one of the most challenging aspects of biotherapeutic development. These tests are vital to providing an accurate picture of potency, stability, and biological activity. But bioassay development can be complex and expensive — and often test results can vary. Cell-based bioassays especially lack robustness. In March 2020, the Biopharmaceutical Emerging Best Practices Association (BEBPA) presented its annual bioassay conference in virtual format. Here, BPI’s senior technical editor reports on the conference’s discussions. Read on to learn more…

Building Orthogonality into Biosimilar Testing

Both the US Food and Drug Administration (FDA) and European Medicines Agency (EMA) have developed regulatory guidelines on biosimilars (1, 2). These comprehensive documents provide clear guidance on what the agencies expect from structural characterization studies. Using state-of- the-art instrumentation and techniques is expected, but the use of orthogonal techniques in structural comparability assessments is also required. The application of orthogonal analytical techniques will provide a firm structural foundation to claims of biosimilarity. Characterization methods verifying and supporting conclusions drawn…

A Future-Proof Solution for Bioprocess Applications: The New Eppendorf Flexible Bioreactor Control System Evolves with the Changing Needs of Modern Biotechnology

In the biopharmaceutical industry’s quality-by-design (QbD) era, optimizing tools for process monitoring and control has become a major focus of development and manufacturing. This increased attention brings challenges into upstream and production processes, cell-line development, process optimization, and scale-up. Suppliers of equipment and technologies also focus on helping their customers improve development timelines. With that increased attention to speed, they are offering tools such as the Eppendorf SciVario twin bioreactor control system to streamline development and maximize flexibility. BPI spoke…

Ask the Expert: Best Practices for Aseptic Sampling from Stainless-Steel Equipment

Turn-key single-use aseptic sampling devices (ASDs) have diminished bioprocess contamination risks significantly. But depending on testing, facility, and storage needs, some ASD container types are more effective than others are. Bobbi Allen (technology expert at Sartorius Stedim Biotech North America, SSB) focused her 8 January 2020 “Ask the Expert” presentation on “what, why, when, and where” operators must sample aseptically from stainless-steel tanks. Using data from in-house testing of aseptic sampling containers, Allen offered key considerations for sterility, process monitoring,…
