Biophysical Methods


Biophysical analytical methods are now playing an increasingly important role in the discovery and development of next-generation biotherapeutics, and these tools are applied for developability evaluation, structural characterization, understanding aggregation, and as important inputs at different stages of R&D. New informatics and instruments are increasingly allowing these methods to be used in a quantitative, rather than qualitative way – and biophysical studies now play a key role in regulatory filings. The PEGS Biophysical Methods conference brings together an international audience of protein scientists and analytical specialists to explore the latest technologies and methods for problem-solving in this dynamic field.

8:50 Discovery Developability Workflow to Utilize Machine Learning Algorithms for Biologics Optimization

Marc Bailly, PhD, Associate Principal Scientist, Merck

The current race to develop better drugs faster has led biopharmaceutical companies into optimizing all drug discovery and development processes. As part of this effort, machine learning algorithms are being developed to identify correlations between amino acid sequences and physicochemical properties observed during drug development. Here, we describe our ongoing efforts aiming at benchmarking such machine learning algorithms to facilitate our drug discovery process.

9:20 Modeling and Experimental Investigation of Avidity-Driven Bispecific Antibody-Antigen Binding Interactions

John Rhoden, PhD, Director, Preclinical Development, Fusion Pharmaceuticals

Multivalent binding of antibodies and bispecifics to cell surface targets can be strongly modulated by leveraging avidity to affect target antigen binding. Avidity-driven target engagement can be exploited to improve properties, such as drug potency and target-cell or tissue selectivity. We demonstrate examples utilizing mathematical modeling as a powerful tool to make mechanistically driven predictions and guide experiments to optimize multivalent proteins, guide dosing, and select desirable targets.

9:50 KEYNOTE PRESENTATION: Machine Learning Applications for Analysis of Process-Induced Protein Aggregates

Theodore Randolph, PhD, Professor, Chemical and Biological Engineering, University of Colorado

Protein aggregates can be produced in almost any processing step and should be carefully monitored and controlled. Recent advances in flow imaging microscopy provide rich data sets of images of particles produced within protein formulations. Machine learning techniques can be exploited to analyze large collections of flow microscope images of aggregates in order to detect process upsets and perform root-cause analyses of process-induced aggregate populations.

11:05 Machine Learning for Sub-Visible Particle Classification

Björn Boll, PhD, Head, Particle Lab and Higher Order Structure Protein Analytics, Physical Chemical Analytics, Novartis Pharma AG, Switzerland

Sub-visible particles, inherently present in all protein drugs, are considered an important safety-related quality attribute of biopharmaceuticals due to their potential immunogenicity. Flow image microscopy techniques allows counting and also discrimination between potentially harmful protein aggregates and harmless pharmaceutical components, e.g. silicone oil. This talk will present a novel application of image analysis via nonparametric Bayesian density estimator to identify silicone oil particles, and a comparison to current benchmarks.

11:35 High-Throughput Investigation of Protein Energy Landscapes in Non-Antibody Scaffolds **

Gabriel Rocklin, PhD, Assistant Professor, Pharmacology, Northwestern University

An ideal therapeutic scaffold should possess both high folding stability and minimal conformational fluctuations, but to date it has not been possible to measure conformational fluctuations on a large scale. We developed a multiplexed hydrogen-deuterium exchange mass spectrometry-based approach for measuring stability and conformational fluctuations for thousands of designed protein scaffolds in parallel. These data should reveal the structural determinants of conformational fluctuations and enable the design of optimized scaffolds.

12:05 pm Automating Protein A through Tryptic Digest LC-MS/MS for Looking at Post-Translational Modifications on mAbs and Multi-Specifics

Stephen D'Eri, Scientist, Sanofi

Rapid technological growth in analytical instrumentation and data processing has enabled researchers to develop powerful new methods for use in the biopharmaceutical industry. Unfortunately, sample preparation methods have progressed at a much slower rate, leading to a bottleneck in high-throughput analytics. By incorporating automation into our sample preparation and data analysis methods, we address the bottleneck issue while supporting harmonization of workflows across multiple sites.

2:30 Emerging Applications for Rapid Surface Plasmon Resonance (SPR) Analysis

Diana Pippig, PhD, Senior Scientist and Team Lead, Functional Characterization, Roche, Germany

While therapeutic antibody and protein formats gain in complexity, it is key to warrant fast- and high-quality target interaction analysis. Cutting-edge SPR analysis allows in-depth characterization and selection of distinct binding modes already in early lead identification. Further, we constantly improve SPR-based QC assay setups and data evaluation in support of process development with a focus on structure-function relationship and physiological context of the compounds.

3:00 Utilizing High-Throughput Differential Scanning Fluorimetry (DSF) to Inform Protein Engineering Decisions

Andrew Urick, PhD, Senior Scientist, AbbVie

As the initial stages of biologics discovery become geared toward generating large numbers of small quantities of material, there is increasing need for sensitive and high-throughput structural assays. Thermostability is an important property for therapeutic proteins, particularly for new biologics formats of increasing complexity. We will describe our implementation of differential scanning fluorimetry to interrogate thermostability in both our protein production and protein engineering workflows.

8:35 Membrane Mimetic FACS to Facilitate Antibody Screening

Christy Thomson, PhD, Senior Scientist, Research, Amgen

The ability to identify and characterize therapeutic antibodies targeting multi-pass membrane proteins is hampered by the often difficult expression and purification of membrane proteins in their native conformation. We examined the utility of novel methods for membrane protein stabilization, including SMALPs, nanodiscs, and amphipols, to isolate a model multi-pass membrane protein. Following successful incorporation into the membrane mimetics, we evaluated their utility in FACS to facilitate lead identification.

NEW APPLICATIONS FOR MASS SPECTROMETRY

11:05 Gas-Phase Structural Biology: New Tools for the Rapid Assessment of Protein Sequence, Structure and Stability

Daniel Vallejo, Researcher, Chemistry, University of Michigan

The next generation of medicines depends upon our ability to quickly assess the structures and stabilities of protein and protein complexes, as well as protein-based biotherapeutics. Such endeavors are nearly insurmountable with current tools without exhaustive orthogonal experimentation. In this presentation, we will discuss recently developed ion mobility-mass spectrometry tools aimed at bridging this gap in basic technology to characterize novel biotherapeutics and their generic analogs (biosimilars).

11:35 From Screening to Mechanism: Using Mass Spectrometry for Small Molecule Drug Discovery

Benjamin Walters, PhD, Scientist, Biochemistry and Cellular Pharmacology, Genentech

Finding chemical matter that can achieve specificity and adequate target occupancy for therapeutic effect drives early discovery research. Drugs that can covalently attach to their targets, in addition to high affinity binding, are an attractive strategy towards this end. This talk discusses recent case studies benefiting from MS approaches to profile covalent fragment libraries, drive SAR, and explore mechanism with hydrogen exchange.

John Kelly, PhD, Senior Research Officer, Mass Spectrometry, National Research Council Canada

NRC has developed nanobodies that act as carriers to shuttle therapeutic payloads across the blood-brain barrier. The antibodies bind to IGF1R on the surface of brain endothelial cells and trigger transcytosis. HDX-MS, integrated with NMR and imaging based structural techniques, is being deployed to better understand the mechanisms by which these antibodies bind to IGF1R and how this differs from interactions with its endogenous ligand, IGF-1.
