KEYNOTE PRESENTATION

13:35 Development of High-Throughput Selection and Screening Methods

Jonas SchaeferJonas V. Schaefer, Ph.D., Head, High-Throughput Laboratory, Department of Biochemistry, University of Zurich

With the help of technology developments, a robust pipeline could be established that already generated valuable DARP in binders (Designed Ankyrin Repeat Proteins, an alternative scaffold), not just covering a variety of different targets but also meeting the high quality criteria important for most scientific projects: monomeric binders that specifically recognize different, non-overlapping epitopes at their targets with high affinities and which can be expressed at high levels in bacterial systems.

14:05 Development of High-Throughput mAb Developability Screening Assays through Detection of Self- and Cross-Interaction

Yingda XuYingda Xu, Associate Director Protein Analytics Adimab

Self- and cross-interaction of an antibody usually leads to developability issues, such as low expression, poor solubility, high viscosity, aggregation and fast serum clearance. Development of high-throughput assays targeting detection of antibody self- and cross-interaction allows elimination of problematic candidates early in the discovery process, minimizing downstream risks.

Genalyte14:35 Detection of Anti Drug Antibodies to a Therapeutic Using a Photonic Ring Immunoassay

Batchelor_AlexAlex Batchelor, General Manager, Europe, Sales and Marketing, Genalyte, Inc.

Recent data demonstrates the exceptional growth in biologic therapeutics across all phases of development. Often, patients taking infused or injected therapeutics can develop antibodies against the drug (ADAs). These ADAs can cause a decrease in efficacy, increased clearance rate, or adverse events. Genalyte has developed an assay capable of detecting and isotyping ADAs with sensitivity and drug tolerance levels exceeding regulatory guidelines. The assay demonstrated concordance with orthogonal technologies while yielding multiplex isotyping profiles, including IgG4.

16:15 Analytical Characterisation of the RNA-Polymerase II inhibitor Amanitin and Amanitin-Based ADCs

Andreas PahlAndreas Pahl, Ph.D., CSO, Heidelberg Pharma

New generations of payloads enter the area of ADC therapeutics including Heidelberg Pharma’s amanitin, a highly effective inhibitor of the eukaryotic RNA Polymerase II. Due to its hydrophilic nature the physicochemical properties differ from well-known tubulin inhibitor based ADCs. This presentation will summarize the current status of Amanitin based ADCs and appropriate methods for their analytical characterisation.

16:45 Characterisation and Comparability Studies for Antibody-Drug Conjugates

Gayathri RatnaswamyGayathri Ratnaswamy, Ph.D., Director, Analytical and Formulation Development, Agensys, Inc.

This presentation will focus on the characterisation of ADCs derived from IgG1 and IgG2 isotypes (derived from hybridoma or CHO cell lines) when conjugated to cytotoxic drugs at the inter-chain disulfides. The results show that the mAb isotypes influence drug loading profiles and this in turn leads to differences in the structure, physico-chemical properties and stability of the resulting conjugates.

9:05 Functional Assay Strategies for Bispecific Antibodies and Fusion Proteins

Joerg MoellekenJoerg Moelleken, Ph.D., Senior Scientist, Large Molecule Research, Roche Pharmaceutical Research & Early Development, Roche Innovation Center Penzberg

The increasing complexity of novel biotherapeutics comprising of Bispecific antibodies and fusion proteins raise new challenges for functional characterisation as compared to standard antibodies. Besides addressing new technical aspects like multi-specificity, and poly-valency, additional biological viewpoints like exclusive or simultaneous target binding need to be considered now. This presentation shows points to consider relevant from lead identification until lead characterisation.

10:35 Coffee Break

11:00 Multi-Parametric Optimisation and Characterisation of Antibody Binding Domains for Chronic Dosing

Orla CunninghamOrla Cunningham, Ph.D., Associate Director, Global Biotherapeutic Technologies, Pfizer

Our aim was to generate a tetravalent bispecific molecule targeting two inflammatory mediators for synergistic immune modulation. Phage displayed mutagenesis libraries were aggressively selected and screened using tailored approaches to identify truly potent AND manufacturable scFv-based bispecifics suitable for subcutaneous administration. Subsequent structural analysis revealed how a very restricted number of CDR-based mutations effectively modulated significant changes in potency and stability.

11:30 Comprehensive Optimisation of a Single-Chain Variable Domain Antibody Fragment as a Targeting Module for a Cytotoxic Nanoparticle

Kathy ZhangKathy Zhang, M.D., MSc, Scientist, Antibody Technology Team, Merrimack Pharmaceuticals

Antibody-targeted nanoparticles increase the therapeutic index of cytotoxic anti-cancer therapies by directing them to tumour cells. We present a case study of iterative engineering of a single chain variable fragment for use as a targeting arm of a liposome-based cytotoxic nanoparticle. Our studies demonstrate that a comprehensive engineering strategy may be required to develop a scFv with optimal characteristics for nanoparticle targeting.

12:00 Developing Quality Product Attributes Using Cell Line Selection Strategies and High-Throughput Analytics

Silke HansenSilke Hansen, Ph.D., Large Molecule Research, Roche Pharmaceutical Research & Early Development, Roche Innovation Center Penzberg

Bispecific antibodies and complex antibody fusion proteins consisting of up to four different polypeptide chains in a single CHO cell line at high quality has been shown to be possible. Diligent cell line selection strategies, supported by high-throughput analytical methods, were keys to the success of identifying cell clones with well characterised cell properties, a stable product profile giving rise to the production of clinical grade API.

BIOVIA12:30 Advances in Antibody Characterization and Collaborative Workflows

Anne Goupil, Principal Field Applications Scientist, Pre-Sales, BIOVIA (formerly Accelrys)

Antibody discovery is driven by complex time consuming experimental processes involving numerous teams. Evolving technologies enable researchers to make more informed decisions early in the process. Here we suggest collaborative and comprehensive capabilities in antibody characterization and development: capabilities to analyze annotate, predict 3-dimensional structures, mutation energies for stability and binding affinity, electrostatics properties, aggregation propensity, developability and more. Collaborative environments for registration, workflow and sharing will be discussed.

CHARACTERISING FOR COMPARABILITY

14:00 Chairperson’s Remarks

HansMartinMuellerHans-Martin Mueller, Ph.D., Director, Bioprocess Development, Merck & Co.





14:05 Comparability for Process Changes throughout Product Lifecycle

Alain BernardAlain Bernard, Ph.D., Vice President, Technical Operations GPS, UCB Pharma

This presentation will describe strategies to implement major process changes during clinical development or after launch of a product on the market. A common denominator to all strategies is to set as an absolute key objective the improvement of product quality. We will illustrate how, a cell line change, or major changes in cell culture media or purification steps can be safely implemented with positive impacts for the patients.

14:35 Analytical and Quality Considerations to Support Product Characterisation Comparability

DaotianFuDaotian Fu, Ph.D., Executive Vice President, Livzon Mabpharm

With wide implementation of QbD in the biotech industry and recent advances in analytical technologies, strategies of analytical characterisation and product comparability continues to evolve. In this presentation, we will discuss implications of QbD applications in process development, and how it may be best used to support process characterisation and product comparability.

15:05 Forced Degradation: A Modern Analytical Tool for Demonstrating Comparability and Similarity

HansMartinMuellerHans-Martin Mueller, Ph.D., Director, Bioprocess Development, Biologics and Vaccines, Merck MSD

Just recently, forced degradation studies became a “super trend” in industry. As an analytical tool, forced degradation studies were applied very successfully to demonstrate comparability of novel biologics and biosimilars. Today, the inclusion of forced degradation studies is just an expectation of regulatory agencies like the FDA when it comes to filing of comparability studies for biologics.

15:35 Product Stability Profiling for Bioprocess Development

Christine P. ChanChristine P. Chan, Ph.D., Principal Scientist/Technical Lead, Global Manufacturing Science & Technology, Genzyme – a SANOFI company

Development of complex glycoproteins requires an array of analytical techniques to adequately understand and control product quality and stability during the bioproduction process as well as storage through the end of shelf-life. This presentation will discuss strategies in product testing and review case studies on characterisation of different proteins in support of process development.
