In this webinar, you will learn:
- The challenges of developing biologics capable of crossing the blood-brain barrier (BBB) and emerging strategies for engineering BBB-penetrant therapeutics.
- Why multispecifics are an ideal vehicle for delivery of BBB therapeutics.
- How multispecifics targeting the BBB can be designed, validated and optimized for efficient transcytosis and TNF-α targeting capabilities.
- Practical insights into characterizing multispecific antibody protein interactions, including binding orientation, avidity optimization, glycosylation considerations, and other biophysical challenges encountered during development.
- About the evolving landscape of BBB-targeting therapeutics and the future of multispecific delivery platforms.
Engineering Multispecifics for Blood-Brain Barrier Transport
The blood-brain barrier (BBB) remains one of the greatest obstacles in developing biologics for neurological diseases. While advances in antibody engineering have created new opportunities to target the central nervous system, designing molecules that efficiently traverse the BBB, while maintaining therapeutic activity without interfering with the receptor’s intrinsic function, requires careful optimization and comprehensive biophysical characterization.
This webinar will explore the development of NanoNewron’s lead multispecific nanobody therapeutic engineered to cross the BBB through transferrin receptor 1 (TfR1)-mediated transcytosis, highlighting the design, validation, and optimization strategies that guided its development.
Attendees will also gain insight into how SPR was used to narrow candidate molecules and inform the assembly of an optimized multispecific therapeutic for BBB transcytosis. The discussion will cover practical challenges encountered during biophysical characterization, and how they were overcome.
