Cambridge Healthtech Institute’s 5th Annual
Process Characterization and Control
A Best Practices Forum for the Translation of Process Understanding into Control Strategies for Maintaining Quality Throughout the Product Lifecycle
August 15-16, 2019
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 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: Process Control as an Enabling Technology for Continuous Vaccine Production
Richard D. Braatz,
PhD, Professor, Chemical Engineering, Massachusetts Institute of Technology
Continuous manufacturing has the potential to significantly improve efficiency, boost production, and reduce the cost of vaccine manufacturing. The presence of defective interfering particles has been shown to result in large periodic variations in virus
titers, limiting overall production rates. This talk describes the design of process control systems that simultaneously remove process oscillations and increase the overall production rate.
2:45 NEW: Biopharm Product’s Structure-Function Relationship (SFR), Rationale for Accelerating Analytical Development and Process Characterization
Wasfi AlAzzam, PhD, CSO, TechnoPharmaSphere (TPS)
SFR aims to measure structural attributes impact on product’s activity and safety profiles, this practice stands true for most pharmaceutics. SFR from in vitro and in vivoprovides in-depth understanding of product’s QA and determine CQA, which help accelerate analytical methods development, acceptance criteria, and product’s specs. SFR results are used to accelerate process characterization, process control strategy, and establishing QBD principles for manufacturing process. SFR is keystone for justifying analytical development acceleration and process characterization & control.
3:15 Process Characterization Planning & Execution for an Effective Product Lifecycle Management
Naveen Pathak, Director,
Pharmaceutical Science, Takeda
Process Characterization is a time and resource-intensive activity to enable process understanding as described in ICH Q8. The presentation will discuss strategies and efficient execution of characterization studies related to determination of control
strategy, successful completion of technology transfer, and lifecycle management. A system for knowledge management of the acquired process understanding over the product lifecycle will be highlighted.
3:45 Featured Poster Presentation: Development of a Rapid Peptide Mapping Method, Using Scaled Down Gradient, to Support Biologics Development
Nandu Madayiputhiya, PhD, Senior Scientist, Celgene
Peptide mapping is extensively used to monitor attributes however, LCMS based peptide mapping is typically a complex, time consuming process and this precludes rapid turnaround time expected for supporting process development. Here we present a simlpe
way for scaling down peptide map gradient for rapid analysis by simply changing the time.100 minute gradient was scaled down to 25 and 12.5 min without compromising the senstivity and accuracy of PTM quantification.

4:15 Process Characterization for Cell and Gene Therapies; Contrast with Protein Therapeutics
Bou-Assaf, PhD, Scientist, Protein & Gene Therapy Biophysical Characterization, Biogen
Gene therapy products comprise a capsid of proteins and a nucleic acid packaged inside. Given the complex structural assembly, advanced analytical tools are indispensable for process characterization. We describe how several analytical tools traditionally
employed for protein therapeutics can be applied as is or adapted to gene therapy products. In addition, we describe challenges uniquely associated with gene therapy products and how they were overcome with new methods and instrumentation.
4:45 Application of High Throughput Chromatography for mAb Downstream Process Characterization
Rowicki, Biologics Process Research and Development, Merck Research Laboratories
High throughput process development (HTPD) approaches are becoming the preferred development approach over traditional lab scale column studies. Key advantages of HTPD include enhanced process understanding and decreases in time and material requirements.
This approach has been utilized to effectively identify operating parameters that significantly impact product attributes and accelerate commercial process development and characterization. A case study describes the strategies, successes, and challenges
of implementing these tools into process characterization.

8:35 Phase Appropriate Approach to Analytical Comparability for Innovator Biotherapeutics: How Much is Enough?
Sonia Taktak, PhD,
Principal Scientist, BioTherapeutics Pharmaceutical Sciences, Pfizer, Inc.
As drug candidates move though development, manufacturing process improvements and formulation changes can impact product quality attributes. The goal of a comparability exercise is to ensure that these changes have no adverse impact on the quality, safety
and efficacy of the drug. In this presentation, we will review key components of a successful analytical comparability strategy based on product-specific considerations, phase of development (early, late) and nature of the change(s).
9:05 Update on BioPhorum’s Roadmap for Inline Monitoring and Real-Time Release
PhD, Associate Director, Bristol-Myers Squibb
Real time monitoring and in-time release of product attributes create a demand to move testing of CPP and CQA from off-line analysis to the manufacturing shop floor (in-line, on-line or at-line monitoring) for reducing speed, cost and maximizing quality
of product. The presentation will focus on the advance in implementation of BioPhorum’s ILM-RTR roadmap strategy related to Business case development and URS completion for a prioritized list of desired CQA’s and CPP, due to be published
as part of a White Paper in 2019.
