From method development to qualification to validation and transfer, it is a continuous yet inter-dependent process from early research to development to QC and release. Depending on which stage of product development you are in, your method may or may
not need to be robust, qualified or validated. The objective is to prove that methods selected are fit for their intended purpose.
With an expanded portfolio of newer formats and non-mAbs in the pipelines, knowledge, experience and advanced techniques are critical to establish efficient, accurate and fit-for-purpose analytical methods that can be later qualified, validated and transferred
to release testing, thereby improving efficiency and reducing cost, time and resources.
Final Agenda
MONDAY, MARCH 12, 2018
7:30 am Registration & Morning Coffee
8:30 Chairperson’s Opening Remarks
Mark T. Fisher, PhD, Professor, Biochemistry and Molecular Biology, University of Kansas Medical Center
8:40 Regulatory Address: Regulatory Perspectives on Analytical Method Validation and Transfer for Biopharmaceutical Products
Ramesh Potla, PhD, Product Quality Team Leader, CDER, FDA
A risk-based approach should be used to determine the totality of evidence needed to demonstrate a successful method transfer. This presentation will focus on our current expectations about the validation and any subsequent site transfer of validated
analytical methods for biotechnology products. Case studies will be presented with the goal of sharing lessons learned during the regulatory review of non-compendial analytical method validation and transfer for licensed therapeutic proteins.
9:20 MAM Method Development and Qualification
Richard Rogers, PhD, Scientist 4, Just Biotherapeutics
We have developed and implemented a mass spectrometry based multi-attribute method (MAM) that monitors known CQAs but also can identify new CQAs on the biotherapeutics. This method has been successfully used in the process development lab. Our goal
is to leverage the MAM for release of biotherapeutics from the quality lab. Method qualification and specification limits for the MAM will be discussed in this presentation.
9:50 The Next Frontier in Subvisible Particle Analysis: New Tools and Potential Opportunities
Danny K. Chou, PharmD, PhD, President, Compassion Biosolution, LLC
In the past decade, we have witnessed the arrival of a large number of analytical technologies that are useful for characterizing sub-visible particles in protein therapeutics. Even with the diverse tools that are available today, there are still
important gaps that have not been filled but yet have a significant role in our ability to fully analyze particles for either product characterization or development purpose. The goal of this presentation is to highlight some of these gaps and
share the potential opportunities that may be captured by new tools that are on the horizon.
10:20 Networking Coffee Break
10:45 Chairperson’s Opening Remarks
Kevin Zen, PhD, Senior Director, Analytical and Formulation Development, AnaptysBio
10:50 Analytical Method Replacement Strategies and Case Studies for Late-Stage Development
and Approved Products
Stephan O. Krause, PhD, Director, QA Technology, Clinical/Commercial Biologics Operations, AstraZeneca
11:20 Developing and Qualifying a Flow Cytometry Assay for Release Testing
Sindhuja Rao, PhD, Senior Scientist, Biotherapeutics & Pharmaceutical Sciences, Analytical R&D,
Pfizer, Inc.
A cellular drug product requires accurate quantification of the level of expression of pertinent cell surface proteins on a per-cell basis. This can be accomplished by flow cytometry, but qualifying a cytometry-based release test is challenging due
to the inherent variability of acquisition and the subjective analysis of the data, as well as software and hardware capabilities. Working through these components led to key learnings for future cellular identity assays.
11:50 Development and Implementation of High-Throughput Assays to Support Process Development
Greg Cantin, PhD, Scientist III, Manufacturing Sciences, Five Prime Therapeutics, Inc.
The development and implementation of high(er)-throughput methods to support process development will be discussed. The two main goals for these activities are: 1) increasing the speed of sample throughput, and 2) achieving acceptable method performance.
Examples of activities that resulted in significant increases in sample throughput will be presented. Additionally, method performance outcomes will be presented for multiple higher-throughput methods that have been implemented.

DART(R) molecules are bispecific antibody-based proteins developed for a variety of indications including immuno-oncology, and are designed to simultaneously bind to two targets. These versatile molecules have the potential for improved efficacy and safety profile through enhanced selectivity and recruitment of specialized effector cells. This presentation will discuss method development and qualification approaches using this novel class of molecules and other antibody molecules as case studies.

8:40 Development and Qualification of an Activity Assay Using a Physiologically Relevant Substrate
Kannappan Veeraragavan, PhD, Head, Method Development Separation Science, Analytical Development, Shire
Mucopolysaccharidosis II (Hunter syndrome) is an X-linked lysosomal storage disease cause by lack of a specific enzyme called iduronate-2-sulfatase (I2S). The in vitro activity of I2S is measured by using
a physiologically relevant substrate (PRS). An assay was developed and qualified to measure the specific activity of I2S which is being manufactured by recombinant technology.
9:10 Development and Qualification of a Novel Cell-Based Assay for Therapeutic mAb against Viral Infection
Dengyun Sun, PhD, Senior Scientist, Biologics Analytical Sciences, Merck
& Co.
We have explored several cell-based assay platforms in support of therapeutic mAb development against viral infection. The advantages and disadvantages of the methods were compared to meet different project needs. In this study, we chose
a luciferase based method and further optimized the assay using Design of Experiment (DOE). The new assay is under qualification in terms of accuracy, linearity, intermediate precision, specification and robustness.
