ARA 290 Peptide
Category: Erythropoietin-Derived Innate Repair Receptor Agonist Form: Lyophilized powder Intended Use: Laboratory research only — not for human or animal consumption
Overview
ARA-290, also known by its investigational name cibinetide, is an 11-amino-acid synthetic peptide engineered from the helix-B surface region of erythropoietin (EPO). It was designed to selectively activate the innate repair receptor (IRR) — a heteromeric complex of the EPO receptor and the beta-common receptor (CD131) — without engaging the classical homodimeric EPO receptor responsible for red blood cell production. This structural distinction is the peptide’s defining research feature: it allows investigation of EPO’s tissue-protective, anti-inflammatory, and anti-apoptotic signaling in isolation from its erythropoietic (blood cell-stimulating) activity. It is supplied here strictly as a raw research compound for qualified laboratory use.

Research Applications
ARA-290 has been referenced in published literature on innate repair receptor signaling, including:
- Small fiber neuropathy research — early-phase human studies in sarcoidosis-associated small fiber neuropathy have reported increased corneal nerve fiber density and reduced neuropathic pain measures
- Inflammatory signaling — preclinical work reports suppression of pro-inflammatory cytokines and inhibition of NF-κB signaling
- Tissue-protection models — published studies include preclinical work on cisplatin-induced kidney injury and cardiac inflammation in animal models
- Diabetic neuropathy and retinal research — additional preclinical interest exists in these areas, though data remains early-stage
ARA-290 previously held FDA orphan drug designation for sarcoidosis-associated small-fiber neuropathy under a now-discontinued development program; no New Drug Application was ever submitted, and there is no active IND. It has not completed clinical development and is not an approved therapy anywhere.
