About the series
Process Analytical Technology (PAT) is intended to support innovation and efficiency in biological therapeutics development, manufacturing, and quality assurance. Conventional biologic manufacturing is generally accomplished using batch processing with laboratory testing conducted on collected samples to evaluate quality, reducing overall efficiency of a process. In-line or near-line measurements of product purity are particularly important to improve efficiencies, reduce risk and improve product quality. The application of variable pathlength (VP) UV spectroscopy allows for concentration measurements in an extended dynamic range. Join us to learn from the experts that have successfully implemented variable pathlength technology into their PAT strategies.

Application of Variable Pathlength Technology for Rapid Determination of Dynamic Binding Capacity
Rashmi Bhangale, Ph.D.
Downstream Process Development Scientist
KBI Biopharma
An ever-increasing demand for biomolecule-based therapies is driving biopharmaceutical companies to accelerate process development activities to remain competitive in today’s industry. Within the downstream process development space, affinity chromatography is widely used for primary capture of monoclonal antibodies, Fc fusion proteins, etc. Optimization of this step requires determination of dynamic binding capacity (DBC) for target protein molecule and can be a lengthy process using traditional methods. KBI Biopharma has applied the use of variable pathlength technology for rapid generation of breakthrough curves and determination of DBC for capture resin selection. FlowVPE, a variable pathlength UV detector from C Technologies, is integrated with the chromatographic system for real time generation of breakthrough curves, reducing the time and cost associated with the development of the primary capture step. This technology helps accelerate the overall process development timeline. Case studies are included.
About the speaker
Rashmi received her Ph.D. in Chemical Engineering from the Institute of Chemical Technology in Mumbai, India. Her research work focused on understanding the mechanisms involved in chromatographic separations for a priori prediction of purification performance. Rashmi joined the Downstream Process Development team at KBI Biopharma in North Carolina in 2018. She is involved in the development and transfer of purification processes for a variety of molecules including monoclonal antibodies, Fc fusions, and enzymes.

CTech FlowVPE System in combination with MALS for Real Time Molecular Weight (RT-MW) Applications
Andres Martinez
Post-doctoral Scientist, Downstream Processing & Real-time Monitoring
Antibody fragmentation and aggregation result in the formation of product-related impurities with the potential of immunogenicity, loss of biological activity and failure of internal and external regulatory standards. Conventional analytics rely on off-line HPLC, usually done well after the analyzed unit operation has ended and no process corrections can take place. Multi Angle Light Scattering (MALS) can provide the real time molecular weight (Mw) of a pure solute or the average Mw of a solute matrix if the total concentration of the species is also available in real time. Analytical experiments with low protein concentration can use conventional fixed path length UV sensors, however these become saturated at the higher concentrations of manufacturing processes. The FlowVPE System enables the real time measurement of protein content in a wide concentration range, which can be coupled to MALS for RT-MW measurements. Besides a more agile process development, RT-MW can enable adaptive processing decisions and inform on product deviations.

Evaluating the new CTech FlowVPX System for UF/DF-Protein Concentration
Jay West
Principal Scientist
Bristol Myers Squibb
An evaluation of a beta version of the FlowVPX and Viper software was performed to determine it’s potential as an inline instrument for product concentration measurement during UF/DF operation, particularly high concentration UF/DF processes that are required for subcutaneous injection formulations (>150 g/L). The FlowVPX has significant potential for GMP and commercial biologics manufacturing unlike the first generation FlowVPE, which was designed as a lab scale instrument. Extensive testing was done using small and pilot scale UF/DF operations with several biologic drugs molecules from the portfolio. The FlowVPX instrument demonstrated very good comparability with other A280 based protein concentration measurements for all molecules tested (six). From a technical standpoint the FlowVPX is a GMP ready instrument, and further testing for instrument robustness and software development is ongoing at present to potentially use the instrument in the GMP space within the near future.
About the speaker
Jay West is Principal Scientist at Bristol Myers Squibb in the Process Development Analytics group in Devens, MA. He obtained his BS in Chemistry from Rensselaer, MS in Chemistry from University at Albany, PhD in Biochemistry from Boston College, and performed postdoctoral research at Northeastern University. He has 10 years pharmaceutical industry experience, working at Regeneron Pharmaceuticals in clinical manufacturing before starting a PhD, and joining BMS in 2014 as an analytical scientist. His focus the past four years has been on Process Analytical Technology, focusing on applications for downstream biologics process development.

Drug Product/Protein Concentration using the CTech FlowVPE System
Raf De Dier
Associate Director for Innovation
in the Clinical Supply Chain
Janssen Pharmaceuticals
Protein concentration is one of the critical quality attributes of fill-finished drug products, as it ultimately defines the dosage a patient receives. Process analytical tools are key in monitoring this attribute and are used to control the manufacturing process accordingly. This presentation will give an overview of the journey from initial laboratory feasibility tests of the FlowVPE technology to implementation into an aseptic GMP facility for in-process control testing of biologics. In addition, the talk will highlight how the online technology sheds new light on the manufacturing process and increases product understanding. Building on the availability of real-time continuous protein concentration data, next steps in the development and implementation of a future automated human-free process execution will be shared.
About the speaker
Raf De Dier holds a Master’s degree in Chemical Engineering and obtained his PhD at the University of Leuven in Belgium and ETH Zürich in Switzerland. He joined Janssen R&D in 2016, where he was responsible for the process development and tech transfer support for liquid and lyophilized drug products in the parenteral fill-finish pilot plant. As part of the Manufacturing Science & Technology group, he lead various cross-functional PAT and process improvement projects. Currently, as the Associate Director Advanced Technology, he drives the proof-of-concept evaluation and implementation of new scientific initiatives across the clinical drug substance and drug product manufacturing sites of Janssen R&D.
