A breakthrough strategy to reverse blood-brain barrier dysfunction

LYS241 monoclonal antibody: counteracting the neuroinflammatory and neurodegenerative processes implicated in the pathophysiology of neurological diseases by restoring the physiological function and integrity of the blood-brain barrier through the restoration of NMDA receptor function

Cytoprotection approach: counteracting neuroinflammation to tackle neurodegeneration

In the pathophysiology of several neurological diseases, hyperactivation of endothelial NMDA receptors by increased expression of endogenous tissue plasminogen activator (tPA) leads to tight junction phosphorylation and degradation, and ultimately blood-brain barrier dysfunction. This allows transmigration of inflammatory cells and toxic molecules into the brain parenchyma as well as activation of microglia, resulting in severe neuroinflammation, a primary cause of neuronal cell death and disease progression.

A unique mechanism of action: a CNS drug which does not need to cross the blood-brain barrier

Lys Therapeutics’ main drug-candidate, LYS241, is a first-in-class monoclonal antibody displaying a groundbreaking mechanism of action counteracting these mechanisms by specifically preventing inside blood vessels the binding of tPA on NMDA receptors, without blocking the physiological function of NMDAr.

By inhibiting this interaction, NMDAr can operate normally, haltering downstream deleterious cellular pathways. Tight junctions are reestablished, endothelial cells return to their healthy state and the blood-brain barrier function is restored, protecting the brain from further neuroinflammatory and subsequent neurodegenerative cascades.

Pipeline

“Glunozumab” maturation program: from a mouse to a fully humanized & optimized lead antibody.

a) Humanization and maturation: refining the parent mouse monoclonal antibody, glunomab, into a library of enhanced variants.
b) Lead clone selection: LYS241, a full-length, Fc silent, igG1 (drug substance).
c) Development of two drug products: the first is an intravenous (i.v.) formulation for acute/single use, and the second is a subcutaneous (s.c.) formulation for chronic/repeated use.
