08:3010:00 | P2: Changing Dynamics in Science: Implementation by Pharmaceutical Industry and Future Adaptation
Moderator: Simleen Kaur, MSc, Biologist, Team Lead, CBER, U.S. FDA

Change is inevitable! Science is continually evolving and advancing. Humans and society have always been hesitant to change. Despite innovative advances in pharmaceutical microbiology, implementation of new technology and science has been slow. Specifically, advances in rapid microbiological testing methods have not been widely implemented by manufacturers, mainly due to the fear of finding unknowns and non-acceptance by regulators. Despite enhanced knowledge of novel technologies, and the concept of dynamic good manufacturing practices (GMPs for 21st Century), there is a constant struggle in adapting new innovations.

This presentation will provide an overview of role of pharmaceutical microbiology in ensuring quality of medicines with examples of changes in microbiological methods, their implementation by the industry to build quality in the product (quality by design, QbD) for achieving sustainable compliance.

Moderator: Christine Sherman, BA, Sterilization & Aseptic Processing Global Microbiology Management, Takeda

Microbiologists gain the most experience and knowledge when events do not go as planned. Still, wouldn’t it be nice to have an expert guide to help Microbiologists navigate the investigation process? Well that help is here! Kim Sobien was part of the team that created Technical Report (TR) #88 - Microbial Data Deviations in the Pharmaceutical Industry. Kim will provide an overview of this new TR and how it can be used to create thoughtful, scientific, and compliant investigations. The second presentation of this session describes how investigational sampling was able to determine root cause in a contamination event. Steven Wieczorek will present the use of Investigational testing to improve contamination control practices by identifying hard to clean surfaces of equipment. Lastly, this session includes Regulatory Expert, Renée Blosser, who will provide an U.S. FDA perspective on Microbiology investigations, root cause determination, and CAPA effectiveness.
