Cambridge Healthtech Institute’s 3rd Annual
Analytical Characterisation of Biotherapeutics

Harnessing Technologies and Proven Strategies to Improve Analytics

2 - 3 November 2016 | EPIC SANA Lisboa Hotel | Lisboa PORTUGAL

Analytics play an important role throughout a product’s lifecycle, from candidate lead selection, to preparation for IND and characterizing for lot release. This is even more important with today’s diverse and complex molecules. The ability to characterize these structures, from sequence to higher structure order, is critical to the understanding of the molecules, its function and behavior, as well as its impact on design and further development. Assessment of the critical quality attributes, developability and aggregation propensity, sequence variants, post-translational modifications and higher-order structure hence become a critical component of analytical development.

CHI’s 3rd Annual Analytical Characterization of Biotherapeutics conference arms scientists with the tools that can speed up innovation, and invites scientists with creative strategies and novel techniques to share their ideas, experiences and solutions to support the development of exciting new biotherapeutics.

In this presentation, we will discuss these challenges on pharmaceutical and analytical development. A case study example will be provided to discuss the strategy to overcome these challenges.

12:00 FTIR Spectroscopy as a Multi-Parameter Analytical Tool for Stability Studies and Batch Consistency Testing of Therapeutic Proteins

Allison Derenne, Ph.D., Researcher, Science-Chemistry, Université libre de Bruxelles

Harnessing the strengths of infrared spectroscopy and recent improvements in chemometric methods, new analytical methods have been developed to study the stability and verify batch-to-batch consistency of therapeutic proteins. The presentation will demonstrate the feasibility, through one quick and direct measurement, to simultaneously obtain information concerning four key characteristics of therapeutic proteins: (i) structural integrity, (ii) quantification of post-translational modifications, (iii) overall protein concentration and (iv) quantification of key excipients.

12:30 Combining Analytical Technologies for the Analysis of Protein Structure and Stability

Stacy Kenyon, Ph.D., Scientist, BioScience Development Initiative, Malvern Instruments Ltd.

The combination of dynamic light scattering (DLS) and Raman spectroscopy increases understanding of protein aggregation and unfolding pathways, and can be applied to high concentration proteins in formulation. Presented here is a case study on the use of combined DLS and Raman spectroscopy to assess the effects of formulation changes on the thermal stability of an innovator product in its original formulation and a biosimilar product in an adjusted formulation, providing information about aggregation pathways.

13:00 Luncheon Presentation: In silico Approaches for Early Assessment of Immunogenicity

Speaker to be Announced
Unexpected adverse events are reasons of drug development failures that contribute to the attrition rate in the pharmaceutical industry. A possible cause specifically associated to Biotherapeutics (peptides/proteins) is immunogenicity: the ability of some biotherapeutics to trigger immune responses that conduct to the generation of antibodies specifically directed against the drug. This immune response can possibly reduce the treatment efficacy and provoke adverse effects. Predicting immunogenicity is proving difficult because of the complexity of the underlying biological processes. We present here an informatics application based on modeling and simulation approaches that can help pharmaceutical R&D to prioritize promising drugs with respect to the immunogenicity risk.

14:00 Chairperson’s Remarks

Peter M. Ihnat, Ph.D., Principal Research Scientist, Drug Product Development Pre-Formulation, AbbVie Bioresearch Center

14:05 Analytical Characterization of Conjugation-Related Events in the Manufacture of ADCs

Richard Beardsley, Ph.D., Technical Development Senior Scientist, Protein Analytical Chemistry, Genentech, Inc.

The manufacture of cysteine-linked antibody-drug conjugates (ADCs) involves the partial reduction of inter-chain disulfide bonds, and subsequent conjugation of the reduced cysteine residues to a maleimide-containing drug-linker. This presentation will focus on the LC-MS characterization of the products of the conjugation reaction, with an emphasis on how various conjugation process parameters may impact reaction specificity.

14:35 Product Characterization and Control Strategy

Ping Feng, MSc., Director, Analytical Sciences and Operation, Teva Pharmaceuticals

Product characterization should be planned based on knowledge of protein sequence and manufacturing process impact. The level of characterization should be phase-appropriate for an adequate balance between risk and benefit. A well-designed characterization study can be very valuable to support commercial specification with reduced release testing or more robust range of a criterion allowed. Two case studies will be presented: antibody glycan analysis and product variant characterization of a HAS fusion protein.

15:05 Advances in Epitope Characterization Using Label-Free Biosensors

Yasmina Abdiche, Ph.D., Research Fellow, Oncology Research Unit, Pfizer-Rinat

This talk will describe methods used to explore the epitope diversity observed across panels of monoclonal antibodies generated by different I and in vivo platforms, including chicken immunizations. High throughput epitope binning experiments on label-free biosensors were used to merge large panels of antibodies and compare their epitope outputs. Data will be presented for both, wild-type and transgenic chickens, highlighting the therapeutic potential of chicken-derived antibodies.
