Preventing Neuronal Damage After Concussion

How our technology works

Mechanism of Action – Our scientists have identified a potentially critical mechanism of neuronal damage and death resulting from concussion. The activation of the protease, calpain-2, is closely associated with cell damage and death following a concussion.

Protease Inhibitors – We have also discovered an inhibitor of this neurodegenerative process. Our proprietary calpain-2 inhibitor provides significant protection when administered after a concussion in animal models.

Blood-Based Biomarkers – Importantly, we have identified a blood-based biomarker that directly correlates with cell death and drug target engagement. N-terminal fragment of brain spectrum (“SNTF”) is generated by calpain activation following a concussion and leaks into the blood.
