Which Program Is Not Accelerated? Increasing Efficiencies in Process Development for Speed, Quality, and Safety

Gisela M. Ferreira, PhD, Director, AstraZeneca

Doing the right thing first time can be greatly informed by prior knowledge. Appropriate scientific assessments support the choice of the molecule that minimizes development effort. Process platforms allows for faster troubleshooting and produces related datasets, therefore increasing the predictive capability of process decisions. Taking smart risks, paralleling activities, appropriate prioritization, standardization and lean design of studies are all examples of tools to accelerate development. The talk will specifically discuss the reuse of columns during clinical production, as an example of a strategy that combines business and scientific arguments to support potential acceleration.

Implementation of N-1 Perfusion in Production of Biologics

Rok Brisar, PhD, Head of Tactical Manufacturing, Novartis

The production of recombinant proteins using mammalian cell culture has become an increasingly important process in the biopharmaceutical industry. The N-1 perfusion method has emerged as a promising approach for improving protein yields and reducing production costs. The aim of this discussion is to explore the advantages and disadvantages of this method compared to traditional batch and fed-batch processes. However, this technology also presents other challenges compared to traditional bioprocessing. Therefore, we will also examine other aspects such as facility design, equipment design, and process reproducibility.

11:00 am

Scaled-Down Models of N-1 Perfusion Enable Screening and Development of Intensified Upstream Fed-Batch Processes

Justin T. Huckaby, PhD, Process Development Scientist, Upstream Process Development, Shattuck Labs, Inc.

A high-seed density upstream fed-batch process was developed through the implementation of N-1 perfusion scale-down models in shake flasks and bench-scale bioreactors. A greater than 50% increase in harvest titer yields with comparable product quality was achieved as proof-of-concept for a bifunctional fusion protein using this intensified seed train process. By adding only a few additional days to the seed train duration, a significant gain in harvest titer can be achieved for increasing overall manufacturing throughput while also reducing the associated costs of goods

Optimisation of Commercial-Scale Intensified Cell Culture

Andrew Sinclair, MSc, CEng, FIChemE, FREng, President & Founder, BioPharm Services Ltd.

Scaling up a bioprocess for manufacturing is complex and the impact of cell culture parameters influence manufacturing modalities. BioSolve Process incorporating Multi-objective Bayesian Optimization is used to analyse the complex design space to help identify optimal solutions. This case study identifies optimal configurations in terms of Fed Batch, Perfusion, or Intensified Fed Batch. The outcomes of the optimisation studies identify those factors that maximise economic, and sustainable benefits.

Maximizing Yield of Perfusion Cell Culture Processes: Evaluation and Scale-Up of Continuous Bleed Recycling

Christoph Herwig, PhD, Founder, Lisalis GmbH, former Professor, Bioprocess Engineering, TU Wien

Bleed recycling is an innovative method to enhance yield in steady-state perfusion processes by concentrating process bleed, selectively removing biomass, and recycling the liquid fraction. This saves significant product otherwise wasted. Inclined gravity settling was compared to acoustic separation as bleed recycling technologies. With similar efficiency and no negative impact on cell viability, nutrient levels, or product quality, it emerged as the preferred technology due to its reduced complexity and scalability. A 3.5-fold bleed reduction with a 19% average harvest rate increase was achieved during a 42-day perfusion process, making it an attractive option to improve process sustainability and yield.

Evaluating Filter Chemistry as a Lever for Improving Perfusion Performance

Alexandria Triozzi, Engineer I, Biogen

Sieving efficiency decline caused by foulants in therapeutic biologics production using continuous manufacturing (CM) is a significant challenge. It is undesirable to pass large quantities of foulants through the filter as it may complicate the downstream purification process. Moreover, membrane fouling may lead to filter failure and eventually batch failure. Adding expensive media additives to improve sieving efficiency might affect cell culture performance, increase cost of goods and may not be as effective across clones or programs. Here, we evaluated three commercially available, commonly utilized membrane chemistries from multiple manufacturers and compared their sieving efficiency performance. 

3:10 pm

Evaluation of a Single-Use Small-Scale Continuous Centrifuge as a Scale-Down Model for Future Manufacturing Continuous Disc Centrifuge

Hirenkumar Panchal, Research Investigator, Incyte Corp.

Continuous centrifugation is commonly used as the initial clarifying stage in the recovery of biopharmaceuticals from cell culture. The benefit of a low shear environment and suitability for manufacturing scale makes the technology a great choice over other methods like depth filtration. However, lack of a proper scale-down model make the implementation of continuous centrifugation usually a try-and-error operation directly at large scale. In this study, with the intention to develop a proper scale down model, we side-by-side compared a single-use pilot-scale centrifuge to a bench-top centrifuge. Turbidity, lactate dehydrogenase (LDH), and host cell protein were all evaluated for comparison. Successful harvesting was accomplished with high yield, great filterability, and low additional cell lysis. The process will be scaled up to a stainless steel continuous centrifuge at manufacturing scale based on the outcomes of the pilot scale conditions.

Commercializing Gene Therapies - The Combined Power of Patient Advocacy and Cost-Effective Manufacturing

Rachel Salzman, DVM, Founder, The Stop ALD Foundation & Global Head, Corporate Strategy, Armatus Bio

There is only a very small handful of FDA-approved gene therapies. This presentation will examine the development of an FDA-approved gene therapy where patient advocacy played a critical role resulting in the first-ever clinical use of a lentiviral vector. Although manufacturing continues to represent a significant challenge throughout the entire R&D journey, there are opportunities for advocacy and manufacturing communities to seek alignment and combine their collective powers to achieve the common goal of increasing patient access to transformative medicines.

A Spiking-Augmentation Method to Improve the Prediction Performance of FTIR-Titer Model on New Molecules

Yuxiang Zhao, PhD, Scientist, Bristol Myers Squibb Co.

Intensified and continuous processes require fast and robust methods for in-line titer monitoring. FTIR and chemometric-based multivariate modeling are promising tools for real time titer monitoring. This presentation demonstrates an adaptive modeling strategy: the model was initially built using a calibration set of available CB samples and then updated by augmenting spiking samples of the new molecules to the calibration set to improve the model robustness.

Optimizing Continuous Chromatography through MPC and EKF: A Novel Approach to Address Resin Aging

Touraj Eslami, PhD, Automation Engineer, Downstream Processing, Institute of Bioprocess Science and Engineering, University of Natural Resources & Life Sciences

The aging of chromatography columns impacts process economics intensively, including productivity, resin utilization, and buffer consumption. Our online optimization approach employs a residence time gradient during the loading step to balance these demands. Using an extended Kalman filter and model predictive controller, the approach can forecast optimal conditions to maximize productivity and resin utilization. Results showed a savings of up to 43% in buffer consumption and increased productivity and resin utilization beyond the feasible range with classic chromatography.
