Applied BioMath (, the industry-leader in applying systems pharmacology and mechanistic modeling, simulation, and analysis to de-risk drug research and development, today announced their upcoming webinar, "Model-Based Approach to Design Bispecific Modalities in Early Discovery" occurs Tuesday, February 4, 2020 at 2p.m. ET / 11a.m. PT.

Understanding drug targets is critical to building an appropriate therapeutic that specifically binds to and elicits the magnitude and duration of response needed for an indication. In this webinar, Jennifer Fretland, PhD, Head of DMPK US, Sanofi, will present a tiered model-based approach used to determine the risk, feasibility, and developability of a bispecific antibody at the early stage to appropriately cover multiple antigen pairs. Once feasibility was assessed, further modeling was performed to determine ideal affinity ranges for each target in bispecific format at the site of action in order to help inform lead generation strategy. Sensitivity analysis was performed to understand each systems pharmacology parameter and its impact on predicted target coverage, which can help prioritize experiments and understand uncertainty earlier in the program. Ultimately, this approach guided teams for informed antibody design, prioritization of experiments, and triaging of challenging antigen pairs.

"A bispecific biologic binding two targets can lead to a variety of effects due to the possibility each antigen may exhibit similar or different kinetic-values. For example, impacting target mediated drug disposition, therapeutic index, and posology ultimately impacts not only developability, but also patients and clinical trials," said John Burke, PhD, Co-Founder, President and CEO, Applied BioMath. "Quantitatively integrating knowledge about the therapeutic with an understanding of its mechanism of action in the context of human disease mechanisms allows us to predict optimal drug properties and prioritize experiments. Doing this analysis before lead generation can help identify the risky projects, but just as importantly, identify and enhance the potential winners."

This webinar is ideal for scientists, protein engineers, and decision makers in R&D who want to learn more about how to leverage Quantitative Systems Pharmacology (QSP) approaches to provide quantitative guidance for their drug discovery and development.
