NTRX-07
A potent and selective CB2 agonist
Immune cells, including microglia within the central nervous system, express CB2 receptors. When activated these receptors can modulate immune cell migration and cytokine release decreasing pro-inflammatory responses. For this reason, CB2 receptors have become the subject of considerable research as a potential therapeutic target to treat a host of neuro-inflammatory disorders.
NTRX-07 is an ideal therapeutic candidate with high affinity for the CB2 receptor while avoiding the adverse psychotropic effects that accompany CB1 receptor-based therapies. Furthermore, it penetrates the blood-brain barrier providing for high expression levels in the CNS.
Multiple pre-clinical studies have demonstrated that NTRX-07 promotes neuronal survival through decreasing pro-inflammatory microglial activity.
NTRX-07 has been shown to decrease neuroinflammation, improve A-beta clearance and improve memory loss observed in Alzheimer disease rodent models.
Pre-clinical efficacy has also been established in multiple neuropathic pain models, including chemotherapy-induced peripheral neuropathy (CIPN), nerve ligation, and complex regional pain syndrome (CRPS) induced by ischemic injury.
NTRX-07 has passed all basic ADMET testing as well as genotoxicity and in-vitro cardiac safety; no in vivo toxicology or psychomimetic effects have been observed. Preclinical safety studies at high doses have shown a good safety profile.
The FDA has issued an IND for NTRX-07 and a Phase I safety study in normal volunteers has been completed. The drug was well tolerated at expected therapeutic doses and no serious adverse event were identified.
