Summary

Cibinetide (ARA 290) is a 11-amino acid peptide derived from the three-dimensional structure of erythropoietin that mimics the tissue-protective but not the hematopoietic actions of EPO. It has been investigated primarily for painful small fiber neuropathy, sarcoidosis-associated neuropathy, and other conditions involving neuroinflammation, ischemia-reperfusion injury, and organ protection. It does not stimulate red blood cell production.

Mechanism of Action

Selectively activates the tissue-protective heterodimeric receptor complex (composed of the EPO receptor and the beta common receptor, βcR/CD131) without activating the classical homodimeric EPOR responsible for erythropoiesis. This triggers cytoprotective, anti-inflammatory, and anti-apoptotic signaling pathways (JAK2, STAT3, PI3K/Akt, NF-κB modulation) in non-hematopoietic tissues including neurons, endothelium, and kidney.
