Cambridge Healthtech Institute’s 5th Annual

Advances in Purification & Recovery

Intensifying and Optimizing Downstream Process

August 14-15, 2019

 

New and emerging molecules coming down the pipeline brings a new set of challenges to the downstream team. Downstream scientists are thus increasingly looking to process intensification and optimization methods, automation, mechanistic modeling and high throughput processes to meet the challenges of higher upstream titers and complex molecules while improving products and reducing cost.

CHI’s 5th Annual Advances in Purification & Recovery invites scientists to share their pursuit of new materials such as nanomembranes, or new technologies including process intensification, high throughput purification and enhanced chromatography approaches. 

 

Final Agenda

TUESDAY, AUGUST 13

6:00-8:30 Recommended Dinner Short Course*

SC6: Integrated Continuous Biomanufacturing – An Implementation Approach

Instructor:

Robert Dream, Managing Director, HDR Company Ltd.

The importance and value of continuous processing’s economic and sustainability advantages due to the modular nature of continuous processes means that the industry is able to adapt more rapidly to changing market demands. Factors other than scientific ones, are the barriers to change from batch to continuous production. The (bio)pharmaceutical industry has reached a stage that requires a change in the production paradigm. Continuous manufacturing is as productive and has a much smaller footprint of the manufacturing plant, avoiding multiple non-value added unit operations. This course will cover strategies to transition from batch to continuous, areas to implement continuous manufacturing (from upstream to fill-finish), step-wise approach to implementation, new technologies and impact of big data, and more.

8:15 KEYNOTE PRESENTATION: Challenges and Innovations in Downstream Processing of Gene Therapy Products

Juan Hernandez Bort, PhD, Head, Gene Therapy Technologies, Takeda

In the areas of gene and cell therapy more than 450 substances are currently in clinical trials and the number of approved products is expected to grow rapidly over the next years. Those products are very complex and require innovative approaches to meet safety requirements, clinical and market demands and cost of goods targets. Smart combinations of traditional downstream approaches and novel technologies are needed to develop scalable and robust purification processes for cell and gene therapy products.

Proportion and complexity of non-mAb bio-therapeutics among approved biologics is increasing. From the bioprocessing perspective, this fact translates into challenges and specific needs that ought to be addressed for those molecules to be safely and economically manufactured. This presentation will address those challenges and provide examples of already existing technical solutions that simplify downstream processes for non-platformable protein therapeutics. Specific emphasis will be given to the primary and secondary purifications steps using affinity chromatography.

NEW MATERIALS AND NOVEL TECHNOLOGIES

1:45 Chairperson’s Remarks

Ronald Bates, PhD, Director, MS&T, Bristol-Myers Squibb

1:50 Perforated Nanomembrances for Separation of Proteins

Alois Jungbauer, PhD, Professor, Biotechnology, University of Natural Resources and Life Sciences, Vienna and Austrian Centre of Industrial Biotechnology

Ultrathin perforated nanomembranes with a thickness below 100 nm can be freely suspended on the cm scale, exhibit high mechanical strength, low surface energies and a sharp permeability cutoff at a hydrodynamic diameter of 10 nm suitable for protein separations. They preserve their robustness in organic solvents and show resistance to high pH values which is ideal for implementation in biotechnological applications. Examples are shown as to how such membranes could be used for downstream processing.

2:20 New Strategies for Magnetic Nanoparticles in Industrial Biotechnology

Sonja Berensmeier, PhD, Professor, Bioseparation Engineering, Technical University of Munich

Magnetic particles are playing an increasingly important role in the field of biotechnology. They have particularly become popular in the field of molecular biology or drug-delivery, where their easy handling has a significant advantage for the user. We show that biocompatible magnetic nanoparticles can also serve as resin for downstream processing. In addition to simple processing even on larger scales, they can be obtained cost-effectively by iron salts and have very large specific surfaces areas.

2:50 Functionalized Protein Nanoparticle Crosslinking for Enhanced Affinity Precipitation of Monoclonal Antibodies

Wilfred Chen, PhD, Gore Professor, Chemical and Biomolecular Engineering, University of Delaware

Affinity precipitation using environmentally responsive, Z-domain-elastin-like polypeptide (Z-ELP) fusion proteins has been shown to be a promising alternative. However, elevated temperature and salt concentrations necessary for precipitation resulted in decreased antibody monomer content and reduced purification capacity. To improve upon the existing technology, we have demonstrated the benefit of conjugating Z-ELP to a 25 nm diameter, self-assembled E2 protein nanocage (Z-ELP-E2), which significantly outperformed traditional Z-ELP-based methods.

LESSONS LEARNED AND ALTERNATIVE APPROACHES TO BIOPROCESS

8:25 Chairperson’s Remarks

Engin Ayturk, PhD, Director, CMC Process Engineering & Conjugation, Mersana Therapeutics

8:30 Learning Opportunities during Commercial Manufacturing

Ronald Bates, PhD, Director, MS&T, Bristol-Myers Squibb

A biotherapeutic product’s lifetime involves thousands of lots encompassing scales from microscale during high-through screening to laboratory and then pilot/early clinical and eventually commercial scale. The vast majority of these lots most likely will occur during commercial manufacturing.This presentation will explore, through case studies and thought-provoking situations, the numerous opportunities available to increase process knowledge after a product is commercialized.

9:00 KEYNOTE PRESENTATION II: The Search for Process Intensification and Simplification: Alternative Approaches versus Current Platform Processes for Monoclonal Antibodies

Robert Gronke, PhD, Senior Principal Scientist, ASO Process Development & Manufacturing, Biogen, Inc.

A platform process approach to production and purification of monoclonal antibodies has been developed and utilized across the Biopharmaceutical industry since the mid 1990s. How a company chooses to maintain vs. evolve their platform will depend on a number of factors. This talk will highlight how best to address changes to the mAb platform, focusing on process intensification and simplification.

ENHANCED CHROMATOGRAPHY AND HIGH THROUGHPUT PURIFICATION

10:45 Leveraging Displacement to Enhance Ion-Exchange Chromatography of Product-Related Variants

Abraham M. Lenhoff, PhD, Allan P. Colburn Professor, Chemical and Biomolecular Engineering, University of Delaware

The combination of protein A chromatography and subsequent polishing steps is routinely effective at removing impurities in mAb bioprocessing. However, for product-related species such as charge variants, the customary use of cation-exchange chromatography may not achieve the needed levels of performance. This presentation will discuss the use of self-displacement to enhance chromatographic performance, specifically for charge variants but also as a more powerful tool for impurity clearance more generally.

11:15 Higher Throughput Purification and Developability of Therapeutic Drug Candidates

Daniel Yoo, Scientist, Biologics, Amgen, Inc.

I will highlight how advances in our higher throughput purification platform, and integration of advanced analytics, have enhanced the speed and quality of challenging molecule production and assessment.

11:45 Enhancing Virus Filter Throughput for Hydrophobic Proteins

Lu Wang, PhD, Assoc Director, CMC Process Development, Teva Pharmaceuticals

Viral safety is one of the major aspects considered by the agency during IND and BLA applications. Downstream manufacturing process has to demonstrate sufficient virus clearance capability to fulfill the regulatory requirements. Virus reduction filtration (VRF) is considered as one of the robust and effective virus clearance steps used in the manufacture of biologics. However, for hydrophobic proteins, VRF process development can be challenging due to filter fouling, which results in low throughput. This presentation is a case study that compares the VRF performance based on protein hydrophobicity, and demonstrate a strategy to improve the viral filter throughput from 100 L/m2 to >600 L/m2 for a product to enable GMP manufacturing facility fit. The aspects considered during VRF development and the proposed mechanisms of improvement will be discussed.
