High Productivity Harvest: Novel strategy for intensifying harvest and displacing depth filtration in fed-batch cell culture
Dr. Kerstin Lange, Team Leader Process Technology, Alvotech
Alvotech developed an intensified fed-batch process using XCell™ ATF technology for the production of a complex fusion protein. The process uses the novel technique of High Productivity Harvest (HPH), which involves a traditional FB process and a clarification process using the XCell™ ATF system. Implementing the new process resulted in higher vcd and viability, improved product quality, and a reduction of cost of manufacture compared to the conventional fed-batch process.

Lunch and Networking
Continuous Protein A chromatography development and implementation using a next generation resin
Dr. Laura Jessica Cranston, DSP Development Specialist, Alvotech, Iceland
Growth of the biopharmaceutical environment is significant within the last couple of years from a drive to reduce production costs and time and whilst maintaining product quality. This has led to increased interest and research into intensifying batch processes or converting them to continuous – partially or completely. This presentation focuses on the development of a Continuous Capture and Viral Inactivation step for a mAb with the use of a next generation Protein A resin. Initial capture resin screenings found a favorite with the Purolite Praesto® Jetted A50. The results documented here highlight the use of this resin in early stage development with studies on binding, thermodynamic behavior of the media and stability. The identification of critical steps impacting product quality attributes and designing them robustly with the use of DOE, whilst allowing flexibility in other steps. The use of a good scale-down model in early stage development, along with constant communication with the manufacturing team, ensures a process which can be transferred smoothly in the future. All the highs, lows and learning curves of developing a continuous step from the beginning with no batch process to fall back on.
Laura did her undergraduate at the University of Glasgow and stayed on to complete her Ph.D. there with a focus on the purification of membrane proteins. She then left Academia behind to work for Alvotech in the Downstream Processing Development department in 2017. Laura is a senior scientist with a focus on initial DSP development and continuous bioprocessing.

SoloVPE® device – Variable pathlength Slope Spectroscopy®
Larry Russo, Director, Global Sales, Repligen
Traditional methodologies relying on fixed-pathlength UV spectroscopy can require several hours for careful sample handling, preparation, and volumetric/gravimetric dilutions to bring samples into the spectrophotometer’s linear range. With Slope Spectroscopy® and variable pathlength analysis, no sample preparation or dilution are required saving substantial time without changing any other aspect of the assay. Processes that involve dilution requirements represent the highest single source of error in traditional UV analysis. By eliminating dilution error, limited linear range, sample preparation and handling, the SoloVPE® Device is superior to traditional fixed pathlength UV technology.
Larry Russo is the Director of Global Sales, SoloVPE® involved with the worldwide implementation of the SoloVPE® variable pathlength UV technology over the last ~10 years. His role has included sales, application, service and development support activities for the solution. He has been with C Technologies, a Repligen Company, for over 15 years and has a MS in Engineering from Rutgers University.
