Cambridge Healthtech Institute's Second Annual

Bioprocess Analytics

( 生物制程的分析法 )

Data Measurement, Monitoring and Modeling Allow Informed Control of Bioprocesses

2018年1月11日 - 12日


The biopharmaceutical industry is meeting increasing demands and costs for biotherapeutics through process optimization. Advanced instrumentation with sampling techniques, new sensor technologies and analyzers have emerged to monitor both upstream and downstream processes. These analytical tools, however, result in large, complex datasets with multivariate interactions. The inherently complex nature of these datasets makes extraction of meaningful and relevant information a difficult task.

Cambridge Healthtech Institute's Second Annual Bioprocess Analytics conference addresses statistical analysis strategies including multivariate data analysis (MVDA), quality by design (QbD), process analytical technology (PAT) and multi-attribute method (MAM), allowing for optimized and informed control of bioprocessing.

Final Agenda


7:45 am Registration and Morning Coffee

Process to Product

8:15 Chairperson's Opening Remarks

Gyun Min Lee, Ph.D., Professor, Biological Sciences, KAIST


8:20 Advances in Protein Purification

John Kawooya, Ph.D., Director, Biologics Optimization, Amgen

9:00 Speed to IND: Alignment and Acceleration of Critical Early Phase Activities

Kyle_ZingaroKyle Zingaro, Ph.D., Development Scientist II, Early Stage Development, Alexion Pharmaceuticals

Speed to IND is the current battle cry across early phase biologics development. Although this faster-is-better approach comes with some risk, new technologies and alignment of workflows can afford both faster and better decisions during this crucial phase of new product development. This is especially true across the Discovery and Process Development handoff including the interface of discovery, preclinical, process, formulation, and analytical teams. Here we present new data and approaches to improve that handoff and detail the impact on timelines and quality of molecules and cell lines in early phase development.

9:30 High-Throughput Cell Line Screening Specific for Perfusion Processes

Jean-Marc Bielser, MSc, Research Scientist, Biopharma Technology and Innovation, EMD Serono

EMD Serono is following the global trend of continuous manufacturing. To support perfusion cell culture development, small-scale semi-continuous screening methods were developed. These methods were applied on a set of different clones and compared to real continuous conditions (lab-scale bioreactors). Growth and productivity performance were compared and helped to define a ranking strategy for screening application, specific to perfusion.

11:00 Glycosylation Flux Analysis of Immunoglobulin G Production Using Chinese Hamster Ovary Cell Culture

Rudiyanto_GunawanRudiyanto Gunawan, Ph.D., Assistant Professor, Institute for Chemical and Bioengineering, ETH Zurich

In this work, we developed Glycosylation Flux Analysis (GFA) for analyzing the flux distribution in glycosylation network of monoclonal antibodies. The application of GFA to Immunoglobulin G (IgG) production using Chinese Hamster Ovary cell cultivations revealed (global) cell metabolic and (local) enzyme-specific alterations in the glycosylation network. The GFA pointed to galactosylation as the key regulator and thus a potential target for controlling IgG glycoform distribution in this system.

11:15 Proteomic Analysis of Host Cell Protein Dynamics in the Culture Supernatants of Therapeutic Protein-Producing CHO Cells

Gyun_Min_LeeGyun Min Lee, Ph.D., Professor, Biological Sciences, KAIST

Host cell proteins (HCPs) accumulate extracellularly during the cultures of recombinant CHO (rCHO) cells, potentially impairing product quality. HCPs accumulated extracellularly in batch and fed-batch cultures of rCHO cell lines were identified and quantified by mass spectrometry. This dataset of HCPs provides insights into determining the appropriate target proteins to be removed during both the cultures and purification steps for ensuring good therapeutic protein quality.

11:30 Using SUREscan™ to Survey Genetic Changes in Stable CHO Cell Lines

Pierre-Alain_GirodPierre-Alain Girod, CSO, Selexis

CHO cells are the most frequently applied host-cell system for industrial protein therapeutic manufacturing. Rapid generation of high-producing clones that don't lose expression capability over time has been a major industry focus. Using SUREscan™ with next-generation sequencing (NGS), we can quickly analyze whole genomes of any cell line, improving traceability of Research Cell Banks (RCBs). In contrast to other CHO published data, we will show that SUREtechnology Platform™ generates RCBs with chromosomally stable lineages.

Statistical Methods for Process Analysis

2:00 Chairperson's Remarks

Mary Ann Brown, Executive Director, Conferences, Cambridge Healthtech Institute

2:05 Novel Hybrid Modeling Approaches for QbD: Getting More from the Combination of Fundamental Knowledge and Statistical Methods

Moritz_von_StoschMoritz von Stosch, Ph.D., Senior Manager, Fermentation, Technical R&D, GSK Vaccines

The combination of fundamental knowledge with statistical methods is referred to as hybrid modeling. These models have been shown to 1) provide better extrapolation properties, 2) have lower data requirements, and 3) are more efficient to develop than models based on a single knowledge source. This talk introduces novel hybrid methods that work more coherently with small datasets and estimate their own prediction quality, such being optimal for the development of the process design space in the context of QbD.

2:35 Phase-Appropriate Analytics

SiowFong_WeeSiowFong Wee, Ph.D., Director, Formulation, Analytical & Bioassay, Aptevo Therapeutics

It can be a struggle to decide how much analytics is considered sufficient for product quality evaluation and characterization to support a project that is in the early development stage. Phase-appropriate analytics to support 'clone-to-clinic' will be presented in this talk.

3:05 Sponsored Presentation (Opportunity Available)

Cell Line Development

4:15 Stable CHO Pool Expression on Steroids (Using Transposon-Mediated Gene Integration)

Gavin_BarnardGavin Barnard, Ph.D., Group Leader, Biotechnology Discovery Research, Eli Lilly and Company

We describe the development and application of a transposon-mediated gene integration system (TMI) to create stable CHO pools. We demonstrate the superiority of TMI relative to random gene integration (RI), the current method of choice used by the biopharmaceutical industry. CHO pools yielding mAb titers as high as 7.6 g/L were generated using TMI. This represents a 3- to 10-fold increase relative to RI for a panel of molecules.

4:45 The Stability of CHO Genome: Essential for Cell Line Characterization or Not?

Noriko_YamanoNoriko Yamano, Ph.D., Senior Scientist, Manufacturing Technology Association of Biologics; Guest Academic Staff, Graduate School of Engineering, Osaka University

The chromosomes in CHO cells frequently cause genomic variations, due to genetic instability. Distribution and stability of chromosomes were examined in CHO-DG44 cells, and two cell lines expressing different numbers of chromosomes were isolated from the original CHO-DG44 cell line to investigate the effect of aneuploid cells on recombinant protein production. In addition, gene expression profiles between cells with disparate chromosome numbers have been compared by mRNA-seq analysis.

5:15 Automated Protein Production with the ExpiCHO Expression System

Joseph_DuqueJoseph Duque, Senior Scientist, Merck Research Laboratories

Combining the ExpiCHO protein expression system with automation enables a high throughput protein production platform that can be utilized to generate a variety of proteins in a short amount of time. Here we discuss the automated systems implemented to minimize the manual steps involved in the protein production process as well as the process development findings in the efforts to try to maximize protein expression from the ExpiCHO system.

Product Characterization and Analytics

9:00 Chairperson's Remarks

Moritz von Stosch, Ph.D., Senior Manager, Fermentation, Technical R&D, GSK Vaccines

9:05 Characterization of mAbs Using Charge Variant Analysis Coupled to High Resolution Native Mass Spectrometry

Jonathan_BonesJonathan Bones, Ph.D., Principal Investigator, Characterisation and Comparability Laboratory, National Institute for Bioprocessing Research and Training

Charge variant analysis (CVA) of biopharmaceuticals is required under ICH Q6B. Issues arise when a new peak is identified in the CVA profile. Here, the development of high resolution charge variant analysis coupled directly to native high resolution mass spectrometry is described that facilitates the intact mass analysis of minor charge variants with high mass accuracy. Application to the characterization of mAbs and other recombinant proteins is described under normal conditions and during forced degradation studies.

9:35 Utilizing High-Throughput Lab Automation and Analytics, Advanced Data Management and Multivariate Statistical Analysis to Define the Formulation Design Space for Biotherapeutics

Michael_SiedlerMichael Siedler, Ph.D., Head, NBE High-Throughput and Advanced Formulation Sciences, Drug Product Development, AbbVie Deutschland GmbH & Co. KG

We discuss adaption and miniaturization of standard analytical methods to be used for 96 and 384 well plates, transition to a data-centric strategy, and implementation of advanced data management to effectively integrate and analyze screening data (including metadata). We also discuss multivariate parameter analysis and statistical modeling to calculate the formulation design space, hence assuring safety and efficacy of new products.

10:05 The Use of Method Performance Monitoring as a Component of a Comprehensive Product Control Strategy

Juma_BridgewaterJuma Bridgewater, Ph.D., Senior Scientist, Analytical Sciences and Technology, Bristol-Myers Squibb

A pharmaceutical product control strategy is designed to ensure that final product quality is representative of product shown to be safe and efficacious. This is not just controlled by testing to specifications but is the result of a comprehensive system of process controls such as raw materials, intermediates and process parameters and analytical testing. High-quality assays must be used for each of these controls and there is a thorough assessment of method performance and robustness when methods are implemented and control limits are defined. However just as for process performance, method performance can vary over time. The use of real-time method performance monitoring supports a comprehensive product control system by providing an assessment of the quality of the data being generated to assess process performance and product quality. This additional dimension to product control can be critical for the early identification of issues that may mask assay failures or yield false positive results that may otherwise go undetected. The collection of this data over time also supports more effective assay and process troubleshooting and the redefinition of assay controls to improve assay robustness.

Higher-Throughput Systems

11:15 High-Throughput Automations and Optimizations for Improved Binder Generation and Validation

Jonas Schaefer, Ph.D., Head, High-Throughput Binder Selection Facility, Biochemistry, University of Zurich

While recombinant binder selection pipelines by now work in rather high-throughput, the screening of suitable affinity reagents and especially the validation of their essential features for the final applications is still laborious and time-intensive. To optimize the efficiency of these processes, we have improved already existing and developed novel methods to efficiently test candidates for their suitability, e.g., regarding their specificity.

11:45 High-Throughput Characterization of Hydrolytic Enzymes in Low Volume and Closed Systems

Nigel F. Reuel, Ph.D., Assistant Professor, Chemical and Biological Engineering, Iowa State University

Hydrolytic enzymes play a significant role in biologic and synthetic processes. The ability to better characterize these enzymes would enable shorter development times and better products. This talk will detail two recent developments for hydrolytic enzyme characterization: 1) a carbon nanotube-based optical sensor that allows for quantitative measurement in <20ul volumes and 2) a resonant antenna sensor that passively transmits its response in the 1-100MHz range, enabling detection within closed, opaque systems.
