Part of CHI's 8th Annual The Bioprocessing Summit

August 18-19, 2016 | Westin Boston Waterfront | Boston, Massachusetts


With the recent publication of process validation guidances from both US and European regulators, the demonstration of process understanding, identification of critical quality attributes and the implementation of well-validated control strategies must now become a routine part of biologics manufacturing operations. But significant ambiguities remain in the specific steps that must be taken in the production of legacy and new products, by companies of different scale and resources and for specific product formats. Process Characterization, Qualification and Control offers a forum for the sharing of strategies and best practices from a wide range of industry companies working to implement these complex new standards.

2:00 KEYNOTE PRESENTATION:
Line of Sight to the Process Control Strategy: A Plan for Commercial Success

Tim_SchofieldTimothy Schofield, ‪Senior Advisor, GlaxoSmithKline‬

The biopharmaceutical control strategy is a covenant between the manufacturer and the customer. Early consideration of manufacturing conditions and constraints, coupled with process and analytical knowledge, inform process and analytical development. The control strategy represents the translation of development experiences and supporting plans to ensure product quality and supply. This presentation highlights a proactive approach to development of a robust control strategy that meets the requirements of both patients and manufacturers.



PROCESS CHARACTERIZATION AND DESIGN SPACE

2:45 DOE Studies in Support of Early Stage Process Characterization

Paul_BigwarfePaul Bigwarfe, Ph.D., Director, Analytical Sciences, Industrial Operations and Product Supply, Regeneron Pharmaceuticals

A DOE is becoming an essential part of the method development life cycle to better understand the acceptable ranges for the method. However, for methods at preclinical and Phase I stages, resources may not exist to evaluate every parameter. A rational strategy has been designed to analyze the most critical parameters for release assays for each new molecule, saving a more comprehensive robustness study for later in development.

3:15 Efficient High-Throughput Biological Process Characterization

Mithell_TaiMitchell Tai, Ph.D., Scientist, Biologics Process Development, Bristol-Myers Squibb

Systems for high-throughput process characterization are poised to greatly improve development timelines. Here we combine the Sartorius ambr250 system with definitive screening design experiments to perform rapid process characterization for a microbial process for recombinant protein production. Main effects screening and process modeling can be generated within a single round of experimentation. The results demonstrate a quality-by-design (QbD) approach for both early-stage process development and late-stage process characterization.

3:45 Considerations for Material Qualification During Process Development

Doherty_StephenStephen Doherty, Ph.D., Department Head, Analytical Chemistry, Toxikon Corporation

This presentation will outline key considerations when selecting material and components for single use systems. Thought processes and evaluation strategies related to the selection of these materials and components will be discussed. This presentation will benefit scientists and engineers engaged in the development, production and implementation of single use systems in understanding in the selection of these materials.

4:00 Refreshment Break

4:15 Multi-Attribute LC/MS Methods for Process Characterization and Design Space Development

Kristin_KrukenbergKristin Krukenberg, Ph.D., Analytical Scientist, Process Development, Shire

Complex biologics provide a unique analytical challenge for characterizing and monitoring multiple CQAs. We developed an LC/MS based approach that provides more detailed information than six “standard” analytical methods reducing analytical testing time and allowing for more comprehensive and timely support of process characterization and development.

4:45 SPEAKER HAS CANCELLED.  DELEGATES MAY ATTEND SESSIONS IN ANY OF THE OTHER STREAMS AT THIS TIME. 

Analytical Considerations for QbD and PAT of Biotechnology/Biosimilar Process Development

Nadine_RitterNadine M. Ritter, Ph.D., President & Principal Advisor, Global Biotech Experts LLC

The value derived from QbD studies and PAT measurements is only as good as the analytical methods they employ. If analytical data are inaccurate or inconsistent due to method performance capabilities, the observations and conclusions could be erroneous. This presentation will highlight some of the most challenging analytical aspects of process characterization, illustrate examples of common mistakes made, and provide recommendations on how to minimize the analytical risks to process design and process control.
