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.

1:50 Perforated Nanomembrances for Separation of Proteins

Jungbauer_AloisAlois 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

Berensmeier_SonjaSonja 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

Chen_WilfredWilfred 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.

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

Lenhoff_AbrahamAbraham 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.

With the increasing challenges of identifying promising therapeutic biologics that produce significant and durable responses for unmet medical needs, the drug discovery landscape has evolved beyond monotherapies to multi-specific and multi-valent formats. However, many of these formats can be difficult to produce efficiently due to byproducts of expression such as aggregation, chain mispairing, disulfide crossed domains, and non-covalently paired species. These molecules require extensive screening efforts to identify the most promising candidates for development. To address this, we developed enhancements to our discovery processes that accelerate and improve screening, increase throughput with automation, and integrate high quality informatics to enable quality decision making.

11:45 Enhancing Virus Filter Throughput for Hydrophobic Proteins

Wang_LuLu 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.
