CELL LINE DEVELOPMENT FOR BACULOVIRUS

4:45 Engineering the Baculovirus Genome for Better Protein Production from Insect Cells

Dominic-EspositoDominic Esposito, Ph.D., Director, Protein Expression Laboratory, Frederick National Lab for Cancer Research

Protein production from insect cells using the baculovirus expression system has proven very useful for the generation of high-quality heterologous proteins when other systems have failed. However, insect cell protein production differs from mammalian expression due to differences in post-translational modification pathways. In order to overcome some of these differences, genome engineering of the baculovirus can be used to “humanize” insect cell protein production. We describe methods for facile modification of the baculovirus genome to both add new pathways for post-translation modification of proteins and also to enhance the stability of baculovirus constructs for protein production.

5:15 Optimizing Insect Cell Lines for Production of Structurally Uniform Glycoproteins

Donald-JarvisDonald Jarvis, Ph.D., Professor, Molecular Biology, University of Wyoming

My presentation will cover previous, as well as more recent and ongoing efforts to produce insect cells with humanized glycoprotein processing pathways. Data will show recent efforts have yielded insect cell lines optimized for human-type protein glycosylation. Furthermore, data will show those cell lines can produce structurally homogenous glycoproteins.

CHO CLONE SELECTION & CELL LINE DEVELOPMENT

8:25 Chairperson’s Remarks

Alan Dickson, Ph.D., Professor and Director, Centre of Excellence in Biopharmaceuticals (COEBP), University of Manchester


8:30 FEATURED PRESENTATION:
An Inducible System for the Rapid Generation of CHO Pools and Stable Clones

Yves-DurocherYves Durocher, Ph.D., Research Officer, Human Health Therapeutics Portfolio, Biologics & Biomanufacturing Program, National Research Council Canada

Using the cumate-inducible promoter, we developed a CHO platform for the rapid generation of stable pools in less than 3 weeks post-transfection. The pools are stable over time and can be used to isolate stable CHO clones showing high productivities. We will provide examples of pools generated for the production of monoclonal antibodies, secreted and membrane proteins. This platform is a useful and cost-effective addition to the large-scale CHO transfection platform for the rapid production of recombinant proteins.

9:00 Screening of CHO Cell Clones by Mass Balance of Amino Acids

Wen-WangWen Wang, Ph.D., Postdoctoral Associate, Chemical Engineering, Massachusetts Institute of Technology (MIT)

Post-transfection clone screening is a crucial step in mammalian cell line development for production of therapeutic proteins. Ideally, the screening should be non-invasive, economical, and effective. We report a fundamentally new method for predicting mAb titer in a Chinese hamster ovary (CHO) cell culture system based on mass balance of two essential amino acids. This study provides an alternative way to screen high therapeutic protein producers in a low-cost manner.

9:30 Stable Glycoengineering of CHO Cells

Claus-KristensenClaus Kristensen, Ph.D., Associate Professor, Copenhagen Center for Glycomics (CCG), University of Copenhagen

Recent advances in precise gene editing technologies such as ZFNs, TALENs and CRISPR/Cas9 systems have enabled stable engineering of mammalian cells to produce well-defined N and O-glycans. In this lecture we will present state-of-the-art glycoengineering in CHO to produce more homogeneous glycans and options for novel designed glycan structures.

10:00 Coffee Break


SYSTEMS BIOLOGY & HIGH-THROUGHPUT TECHNIQUES FOR DEVELOPING CELL LINES

10:45 Developing Systems Biology Models Based on Whole-Genome Sequencing of CHO to Guide Cell Line Engineering

Nathan-LewisNathan Lewis, Ph.D., Assistant Professor, Systems Biology Research Group, University of California, San Diego

Our recent whole-genome sequencing efforts for CHO have enabled the construction of systems biology models of metabolism, protein secretion, and glycosylation. We now use these for detailed analysis of -omics data from CHO to deepen our understanding of differences between host cell lines and to guide our cell line engineering efforts. These efforts aim to enhance cell growth, tailor protein modifications, and improve protein secretion, in order to better control biotherapeutic critical quality attributes.

11:15 Utilizing High-Throughput Bioanalytics for Early Detection of Product Impurities

Christina Alves, Ph.D., Scientist, Cell Culture Development, Biogen Idec, Inc.

Improvements in the throughput and efficiency of analytical techniques have enabled their use earlier on in the cell line development process. This in turn provides useful information on a large number of clones at a very early stage. In this case study we demonstrate how the use of these techniques allowed early detection of product impurities which in turn prevented delays in clinical timelines and the need for additional resources.

11:45 High-Throughput Product Quality Assays for Cell Line and Process Development

Shashi Prajapati, Ph.D., Senior Scientist, High-Throughput Analytical Group, Cell Culture Development, Biogen Idec, Inc.

Cell line and process development play a major role in producing therapeutic proteins with high productivity and appropriate product quality attributes. To support this development, analyses of large number of samples generated from thousands of clones and process optimization are critical. Analyzing large number of samples has been a bottleneck in biotech industries because conventional analytical assays are low-throughput. Here we present various high-throughput (HTP) analytical platforms to facilitate rapid and parallel analyses of product quantity and quality using 96-well plate formats. These platforms include HTP protein quantitation followed by HTP protein purification and product quality analyses. With these analytical capabilities, we can assess product quality in the early stage of clone screening, as well as expedite the cell line and process development.

INNOVATIVE TECHNOLOGIES & STRATEGIES

1:25 Chairperson’s Remarks

Pamela Pegman, Ph.D., Senior Principal Scientist, Cell Line Development, Pfizer, Inc.

1:30 Development of Synthetic Biology Tools to More Predictably Clone, Express and Select Active Biologics in Cell Line Development

Ian-FotheringhamIan Fotheringham, Ph.D., Managing Director, Ingenza Ltd.

In this talk, I will describe how Ingenza has developed and deployed various synthetic biology tools to enable us to more predictably clone, express and select active proteins during cell line development. I will use real-world examples of solving customer problems to illustrate the utility of our approach. These tools include protein engineering to address poor response kinetics during the control of gene expression, the development of synthetic “landing pads” to optimize the genomic operating environment, and the use of genome editing and RNA trafficking systems. 

2:00 Enabling Evaluation of Polysaccharide Size and Content for DOE Studies in Early Process Phases

Erwin Swennen, Ph.D., Manager, Cell Line and Process Analytics, Bacterial Drug Substance Development, Novartis Vaccines

This talk presents the development of an innovative RP-SE(GPC) analytical method to monitor both critical quality attributes of GBS capsular PS during all phases of the production process. This method enabled DOE studies also in early process phases with complex matrix, and contains a practical approach on how industrial R&D is trying to keep up with the constant increase in quality requirements by regulatory agencies (QbD, DoE in early phases). The method represents a new out-of-the-box application of technology.

2:30 Development of Human Cell Systems for Evaluating the Responses of Drugs Directed at Correcting the Function of Cellular Proteins

Dieter-GruenertDieter Gruenert, Ph.D., Professor, Otolaryngology-Head and Neck Surgery, University of California, San Francisco

Our lab has been a leader in the development of these cell systems that have been used in academic and industry settings nationally and internationally. We have developed human airway epithelial and iPS cell systems to evaluate and screen the responses to drugs aimed at correcting the function of proteins involved in airway diseases such as cystic fibrosis.

3:00 Networking Refreshment Break

3:15 GlycoExpress: A Toolbox for the High Yield Production of Glycooptimized Fully Human Biopharmaceuticals in Perfusion Bioreactors at Different Scales

Rainer Stahn, Ph.D., Head, Bioprocess Development, Glycotope GmbH

GlycoExpress cells producing mAb are cultivated with perfusion bioreactor systems applying different cell retention mechanisms such as centrifugation (centritech) or alternating tangential flow (ATF) filtration at different scales. Growth, product yield and product quality, especially glycosylation, are evaluated during the cultivation. Perfusions culture helps to keep cells in the optimal growing and production phase over the production process which leads to highly stable product quality allowing a flexible duration of the run in one batch size.

3:45 Setting Pre-Work Priorities and KPIs to Avoid the Most Significant Challenges during Tech Transfer

Jayant-AphaleJayant Aphale, Ph.D., MBA, Senior Vice President, Technical Operations, Sarepta Therapeutics

Communication is essential before, during, and after the tech transfer process. Pre-tech transfer activities are critical in ensuring success of the tech transfer process. You must have the appropriate skill sets and competencies in place with all of your upstream / downstream partners so that you have understood any constraints and agreed on the scope of the work and acceptable parameters months before tech transfer begins.
