P1: The New Frontier of Personalized Medicine: Regulatory Expectations and Microbiological Challenges
EU Moderator: Kerstin Wilken, PhD, PMP,
Director, Programs and Education, PDA Europe
US Moderator: Kim Sobien, Principal Sterility Assurance Engineer, PETNET Solutions | A Siemens Company

Imagine using your own body’s cells to cure cancer – the idea has recently been made tangible and has been shown to be successful with new discoveries in the field of immuno-oncology. CAR T (Chimeric Antigen Receptor T-Cell) therapy is a novel cellular therapy that supercharges a patient’s own immune system T-cells and programs them to attack designated cancer cells in the body. Significant challenges with facility design, room classification, manufacturing, testing, and regulatory approval have been brought forth as several of these personalized “living drug” therapies have achieved commercialization. This opening plenary session will explore CAR T product manufacturing challenges from an industry perspective and discuss regulatory challenges for commercialization as well as the use of non-compendial microbiology methods.

A1: The Trouble with Sterility
Moderator: Edward Tidswell, PhD, Executive Director, Microbiology QA, Merck & Co., Inc.    

Sterility is an absolute and binary concept – we categorize therapeutics either sterile or non-sterile. Yet the modality of imparting sterility, sterile manufacturing, and the method of proving sterility remain challenging and possibly one of the greatest potential risks to patient safety. Regulatory expectations, compliance observations, and the cadre of contemporary microbiological tools all used to assure sterility will be discussed to provide a picture of how to avoid trouble with sterility.

Moderator: Irving Ford, Head of CAR-T QC Laboratories, Celgene

The challenges raised by new products, test methods, and manufacturing processes present great opportunities for innovative approaches in microbiology. The introduction of these new elements is changing the way that we think of microbiology, and forcing the industry and regulators to look at new approaches for process control and product release. This session will explore a novel process, test method, and product to provide unique insights into how the future is quickly becoming the present.

A2: Microbial Control
Moderator: Amy McDaniel, PhD, Microbiologist, CDER, FDA

The external environment to a manufacturing process presents a significant source of microorganisms. The potential for microbial ingress from the external environment poses a great challenge for microbial control. This session will focus on controlling a process “from the outside in,” through case studies on equipment contributions and use of EM data to protect a process prior to microbial ingress. The goal of the knowledge sharing will be to incorporate elements into your own microbial control strategies and to improve programs for the future.

B2: Small Mold: Big Problem! Case Studies on Mold in a Manufacturing Facility
Moderator: Ebony Arrington, MS, Pfizer Global Supply, Production Operations, Central Support Manager, Pfizer Biotech

In the wide diversity of the microbial world, mold represents a relatively small portion of the possible overall contaminants. However, the presence of mold within a pharmaceutical manufacturing facility creates the need for heightened awareness and response commensurate with the risk that it poses to the process and ultimately the patient. In this session, two case studies will be presented related to the presence of mold either in the environment or in the process of a pharmaceutical manufacturing facility. The impact and response to the situations will be explored to provide insight into the prevention of future recurrence.

Moderator: Julie Barlasov-Brown, MBA, Associate Director Sterile and Microbiology QA, Merck & Co., Inc. 
Hosted by the Microbiology/Environmental Monitoring Interest Group

This session will focus on electronic notebooks (ELN), data integrity, and capturing data in the microbiology laboratory. As we move into the future, expectations on data capture and integrity are becoming more of a question. The discussion will focus on how the industry can prepare to meet these expectations as well as what can be done at the laboratory level to provide excellent product quality.

Tessa Patton will provide a presentation on the implementation of ELN at Eurofins Lancaster Laboratories followed by roundtable discussion about current practices and lessons learned.

Our two speakers are well-known on both continents for their long experience in pharmaceutical microbiology, investigations and troubleshooting, and their passion for alternative micro methods. Dr. Michael Miller will present an overview of the more recent revision to regulations and guidances to define strategies for short-shelf lives medicines such as cell and gene therapy products. Jeanne Moldenhauer will give a focus on the infamous Burkhoderia cepacia complex and novel methods for eradication of this contamination as well as preventative measures.

A3: Environmental Monitoring
Moderator: Christine Sherman, Director, Global Microbiology and Aseptic Network, Takeda

In order to assure control of manufacturing facilities, environmental monitoring (EM) programs are critical to evaluate the effectiveness of disinfection programs, operator’s aseptic practices, and the engineering controls in place which provide appropriate conditions for manufacture. These programs generate large amounts of data which can make it difficult to determine the best focus of valuable resources. This session will highlight a case study which provides guidance and tools to evaluate personnel gowning data to assess trends and risks. The second case study evaluated the impact of facility changes on sterility assurance and how to determine the most efficient and effective EM performance qualification after modification of the facility.

A4: Risk Identification, Assessment, and Mitigation
Moderator: Yeissa M. Chabrier-Roselló, PhD, Microbiology Reviewer, CDER, FDA

A microbiological risk assessment is the scientifically-based process to estimate the likelihood of exposure to a microbial hazard and the resulting impact from this exposure. While the overall tools for quality risk management have been well described (ICH Q9), the practical applications for microbiology continue to present opportunities. This session will present three unique case studies on microbiological risk identification, assessment, and mitigation. It will include real-life perspectives on reactive microbiological risk assessment reports, improvements in aseptic processing to prevent microbial contamination, and manufacturing situations where the shelf life of the product influences the need to build risk reduction into the overall manufacturing processing. This session will emphasize the importance of design with a risk in mind for manufacturing operations upstream and downstream of the final drug product.

Questions and Answers/Discussion

B4: Predictably Irrational Microbiology
Moderator: MaryEllen E. Usarzewicz, MS, Parenteral Manufacturing Support Lead, Analytical & Bioanalytical Operations, Microbiology, Bristol-Myers Squibb

Despite best efforts at performing testing in a consistent, predictable fashion, the nature of microbiology is such that the living organisms sometimes do not provide rational results. Predictability also includes the repetitive nature of performing an action in the same way, even if the action (or test) does not seem rational. This session will focus on the predictably irrational nature of microbiology (from the perspective of both testing and results), including case studies on disinfectant efficacy evaluation and recovery of an anaerobic microorganisms from an aerobic aseptic process simulation.
