13:45 Engineering Vector Components and Host Cells for Next-Generation Bioproducts

James_David_CDavid James, PhD, Professor, Bioprocess Engineering, Chemical and Biological Engineering, University of Sheffield

Engineering complex cellular performance characteristics is an unpredictable challenge made more difficult by the variability of CHO cell lines, protein products, and production processes. There is no one-size-fits-all solution. As a new paradigm for cell line development we are developing a hyper-variable design space for mammalian cell factory engineering that utilises directed and synthetic variation of chemical, genetic, and cellular input components as a core strategy to optimize cell functional performance beyond natural limits.

14:45 Precise Genome Engineering of Hybridomas for Antibody Expression and Screening

Parola_CristinaCristina Parola, PhD, Postdoctoral Research Scientist, Biologics Research, Sanofi

By taking advantage of precision genome editing with CRISPR-Cas9, we have developed a novel mammalian cell platform for the expression of full-length antibodies in hybridoma cells. The Plug-and-(Dis)play (PnP) workflow included the initial generation of a reporter, antibody-negative cell line; in the subsequent reprogramming step, a novel specificity is introduced by means of a synthetic antibody. Finally, we optimized HDR efficiency to render the system amenable to the expression and screening of B cell repertoires: this feature allowed the de novo discovery of antibodies from immune libraries.

16:20 Bispecific, Soluble TCR as the Next Therapeutic Platform

Bahija Jallal, PhD, CEO and Director of the Board, ImmunocoreBahija Jallal, PhD, CEO and Director of the Board, Immunocore

Of the two adaptive immunity recognition motifs, only antibodies have been brought to patients. However, antibody therapeutics only recognize 10% of human proteome (surface-expressed). The other motif, T cell receptor (TCR), has potential to unlock 90% of the human proteome, but requires converting a low-affinity, specificity membrane receptor into a soluble therapeutic. IMCgp100, a soluble, TCR bispecific-targeting melanoma, is the most advanced soluble TCR therapeutic in development.

17:20 Attacking Cancer Cell Surfaceomes with Recombinant Antibodies

James A. Wells, PhD, Professor, Departments of Pharmaceutical Chemistry and Cellular & Molecular Pharmacology, University of California,
	San FranciscoJames A. Wells, PhD, Professor, Departments of Pharmaceutical Chemistry and Cellular & Molecular Pharmacology, University of California, San Francisco

The cell surface proteome (surfaceome) is the primary hub for cells to communicate with the outside world. Oncogenes are known to cause huge changes in cells and we find this translates to significant remodeling of the surfaceome. We generate recombinant antibodies to detect and then attack these cells by toxifying the antibodies or recruiting immune cells to kill. I’ll discuss the technologies for surface protein analysis, an industrialized platform for rapid antibody generation using phage display, and using these tool reagents for target validation.

08:35 Integrating Cell-Free Expression, Purification, and Bioconjugation

Casteleijn_Marco_(Marinus)Marco G. Casteleijn, PhD, Senior Researcher, Industrial Biotechnology, VTT Technical Research Institute of Finland

We aim to develop new tools for cell-free protein synthesis. For example, to integrate protein expression, purification, and bioconjugation in small volumes coupled with cell-free protein synthesis. We compared light triggered release with traditional affinity chromatography. Moreover, we explored transferring a moiety from a captured peptide to the target protein without further purification steps and used time gated Raman spectroscopy to evaluate protein quality.

09:05 Development of a High-Yield Cell-Free Synthesis Platform from Pichia Pastoris

Polizzi_KarenKaren Polizzi, PhD, Reader in Biotechnology, Department of Chemical Engineering, Imperial College London

Pichia pastoris (syn Komagataella spp.) is a methylotrophic yeast used in recombinant protein manufacture because of its high volumetric productivity. We have developed a CFPS platform using P. pastoris via optimisation of reaction conditions and vector design and overexpression of global regulators of ribosome synthesis to increase overall yields. The result is a system that is suitable for prototyping vectors before strain development or manufacturing of proteins directly.

11:15 Synthetic Platform for in vitro Glycoengineering of Proteins by a Cell-Free, Compartmentalized Multi-Enzyme Cascade

Rexer_ThomasThomas Rexer, PhD, Team Lead, Synthetic Glycobiotechnology, Bioprocess Engineering, Max Planck Institute for Dynamics of Complex Technical Systems Magdeburg

N-linked glycans attached to proteins are involved in a wide range of processes such as biological recognition, protein stability, immunogenicity, and antigenicity. Therefore, the glycosylation of proteins is an important parameter to be considered in the optimisation of animal cell culture-derived drugs including monoclonal antibodies. The presented cell-free system is an integral part of a synthetic platform for in vitro glycoengineering of proteins by model-supported, cost-efficient and scalable biocatalytic processes being established by our group.

11:45 Cell-Free Based Approach for Rapid Screening of Antibody Fragment Libraries

Moradi_Shayli_VShayli Varasteh Moradi, PhD, Research Associate, Science and Engineering School, Queensland University of Technology

Cell-free protein expression system (CFPS) allows the robust production of recombinant proteins in a multiplexed format. We developed a rapid method for antibody fragment libraries screening based on eukaryotic Leishmania tarentolae (LTE) system in combination with AlphaLISA technology to study protein-protein interaction. The presented technique provides a powerful tool for rapid protein binders’ selection with high sensitivity and throughput.

14:20 KEYNOTE PRESENTATION: Unique Engineering Targets for Antibody Production Cell Lines: Selection, Cloning, Glycan Modifications, and Chromatin Readers

Volker Sandig, PhD, CSO, ProBioGen AGVolker Sandig, PhD, CSO, ProBioGen AG

Omics approaches are often applied to determine holistic strategies to improve key cell line attributes: yield, stability, robustness, and product quality. Instead, we have selected important junctions in known pathways to enhance cell line performance. We will show how transgene cassettes embedded into transposons can be directed to most active genomic loci taking benefit of natural chromatin reader domains, discuss the impact for bispecific antibodies, and look into pathway deflection to set specific glycan features.

14:50 Development of a Pre-Glycoengineered CHO-K1 Host Cell Line for the Expression of Antibodies with Enhanced Fc Mediated Effector Function

Popp_OliverOliver Popp, Dr. rer. nat., Principle Scientist, pRED, Large Molecule Research, Roche Diagnostics GmbH, Roche Innovation Center Munich

Here, we present the development of a glycoengineered CHO-K1 host cell line, stably expressing β1,4-N-Acetylglucoseaminyltransferase III and α-mannosidase II, for the expression of a-fucosylated antibodies with enhanced Fc-mediated effector function.

15:20 Expanding the CHO Cell Line Development Toolbox to Enable Fast-Track Development of Innovative Biotherapeutics

Schmieder_ValerieValerie Schmieder, PhD, Postdoctoral Researcher, Cell Line Development, Bioprocess Development Biologicals, Boehringer Ingelheim Pharma GmbH & Co. KG

The increasing demand for novel biotherapeutics is driving the generation and implementation of innovative as well as disruptive tools for cell line development (CLD) in CHO. Additionally, more and more complex molecules, such as multi-specific antibodies, are further challenging the production of therapeutic proteins from CHO. Here, we present our recent achievements in the use of state-of-the-art technologies to overcome current and future challenges in CLD.

17:00 Combining a CRISPR Library with Phenotypic Enrichment to Identify Gene Engineering Targets in CHO Cells

Keogh_NiamhNiamh Keogh, Research Scientist, Niall Barron Laboratory, Chemical and Bioprocess Engineering Department, National Institute for Bioprocessing Research & Training

CRISPR Technology has the ability to fundamentally change the capabilities of genetic engineering. My work focuses on using CRISPR/CAS 9 to generate individual knock outs of genes as well as using a CRISPR Library approach to create genome-wide loss of gene function studies with the overall aim of discovering potentially beneficial gene targets for CHO cell line engineering.

17:30 Study of the Impact of Proximal Chromosomal Environment Alterations Using a Targeted Integration CHO Host Cell Line

Mark Trautwein, Dr. rer. nat., Senior Scientist, Biologics Research, Bayer AG

Both the chromosomal environment of the integration site as well as the genetic elements of a transgene expression cassette contribute to the degree of high and stable transgene expression. We have used a targeted integration host cell line to study the impact of different alterations in proximal chromosomal environment as well as in different genetic elements of the transgene construct. This approach facilitates optimization of product-specific expression configurations.

18:00 Rethinking Gene Expression Using the Synthetic C3P3 Transcription System

Jais_PhilippePhilippe H. Jais, MD, PhD, President and CSO, Eukarÿs SAS

Eukarÿs has developed the first ever artificial expression system by synthetic biology that is named C3P3 (cytoplasmic chimeric capping prone-phage polymerase). This enzymatic system, currently in its 3rd generation, synthesizes in vivo high amounts of mature messenger RNA and, consequently, protein of interest in mammalian cells. Besides its uses for therapeutics, the C3P3 system is used as a potent tool for the bioproduction of viruses and proteins.
