Tonix Pharmaceuticals Holding Corp. licensed exclusive worldwide rights to TNX-4900, a small-molecule candidate for chronic neuropathic pain, from Rutgers University. TNX-4900 is a highly selective Sigma-1 receptor antagonist with nanomolar affinity (Ki = 7.5 nM) and more than hundred-fold selectivity over Sigma-2, intended as a non-opioid approach to treating neuropathic pain.
In preclinical models of diabetic and chemotherapy-induced neuropathic pain, TNX-4900 produced significant and durable reductions in pain behaviors after both acute and chronic dosing, without evidence of tolerance or motor impairment. The compound shows high blood-brain barrier penetration and oral bioavailability of approximately 28%. Tonix plans additional pharmacokinetic, formulation and safety studies to potentially support an Investigational New Drug application with the U.S. Food and Drug Administration.
