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, and increasing biosimilar products. 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 comparability and biosimilarity analysis.

CHI’s 3rd Annual Analytical Characterization of Biotherapeutics conference explores approaches to comparability and biosimilarity assessments; highlights tools and techniques for characterization of ADCs, fusion proteins and bispecific antibodies; discusses strategies for detection of product- and process-related impurities and presents a regulatory perspective on potency assays.

BIOSIMILARITY AND COMPARABILITY ASSESSMENT

08:30 Chairperson’s Remarks

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


08:35 KEYNOTE PRESENTATION:
High Throughput Assays for the Quantification of the Potency and Comparability of Biosimilars and Innovator Products

MIchael_ToveyMichael Tovey, Ph.D., INSERM Director, Research, Laboratory of Biotechnology & Applied Pharmacology, Ecole Normale Supérieure de Cachan

Successful development of biosimilars is dependent upon direct comparisons of the relative potency and comparability of innovator molecules and biosimilars. A validated standardized high throughput 384 assay platform will be described that is applicable to most biopharmaceuticals and that allows direct comparison of drug potency and comparability of innovator molecules and biosimilars in the same assay. Case studies will be presented for products ranging from Neupogen to Remicade and Enbrel.


09:20 Characterization of Filgrastim Using Intact and Top-Down MS

Urs_LewandrowskiUrs Lewandrowski, Ph.D., Lab Head, Analytical Characterization, Sandoz

The detailed analytical comparison of Zarxio and the reference product Neupogen provided the foundation for FDA’s approval of Sandoz’s Zarxio as the first biosimilar in the United States. Intact and top-down MS are becoming highly attractive techniques for detailed protein characterization. Using a benchtop Exactive MS, modifications in filgrastim were detected with high sensitivity on the intact level followed by site assignment using all-ion fragmentation mode. Examples of successful top-down MS experiments will be demonstrated.

10:50 Coffee Break in the Exhibit Hall with Poster Viewing

11:30 Overcoming Formulation and Analytical Challenges for Developing Biosimilar Products

Jun Liu, Ph.D., Senior Director, Analytical and Pharmaceutical Science, Coherus Bioscience

Due to the complex nature of biopharmaceuticals, analysis and control of the similarity of biosimilar products to innovators products remains key challenges. Furthermore, critical IP on formulation and process provided additional challenges to introduce biosimilar products into major US and EU markets. 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_DerenneAllison 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 Assessing an Interaction Parameter for Bioformulation Stability in One Measurement, using TDA Concentration Gradients

Trikeriotis_MarkosMarkos Trikeriotis, Ph.D., Applications Development Scientist, Malvern Instruments Ltd.

The self-association characteristics of molecules in dilute solutions can provide an assessment of stability at an early stage. The diffusion interaction parameter (kD) is a measure of the propensity for self-association, but the determination of this parameter using existing methodologies requires several measurements over a concentration series. Here, we show how Taylor Dispersion Analysis can be used to generate a concentration gradient from which the kD can be extracted in a single, low volume measurement.

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.

TOOLS AND TECHNIQUES FOR PRODUCT CHARACTERISATION

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_BeardsleyRichard 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_FengPing 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_AbdicheYasmina 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.

16:15 Investigating the Interaction between FcRn and IgG Variants by Hydrogen/Deuterium Exchange Mass Spectrometry

Maximiliane Hilger, Ph.D., Senior Scientist, Mass Spectrometry, Large Molecule Research, Pharma Research and Early Development, Roche Innovation Center Munich

The recycling of IgGs by FcRn regulates antibody plasma levels and half-life. Here we study the IgG1–FcRn interaction by HDX-MS to gain deeper molecular understanding that will ultimately allow us to optimize antibody pharmacokinetics, efficacy and safety. Interestingly, our data demonstrate a conformational interplay between the Fab and Fc regions of the antibodies upon FcRn binding and suggest the presence of direct FcRn interaction sites in the Fab region.

16:45 Using Viscosity-Derived Parameters and Thermal Analysis to Evaluate the Solution Properties of Bispecific Dual Variable Domain Immunoglobulins

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

The Fab regions of dual variable domain immunoglobulins (DVD-Ig) consist of outer and inner complementarity determining regions (CDR) that confer bivalent antigen specificity.
