Research overview

DoseGear research brief

Ara 290 is an engineered 11-amino acid peptide activating the Innate Repair Receptor (IRR) to provide tissue-protective effects without red blood cell stimulation. Has FDA Orphan Drug status.

Mechanism of action

Activates IRR through EPOR/β-common receptor complex, triggering tissue-protective signaling without erythropoietic effects.

Compound background

Development & research timeline

Study windows describe what researchers measured, not when an individual should expect a result.

Origin & development

Engineered EPO-derived helix-B-surface peptide, also called cibinetide.

What it is researched for

Small-fiber neuropathy, tissue protection, and diabetic-complication research through proposed innate-repair-receptor signaling.

Research observation window

Human neuropathy studies used 28 days; a diabetic macular-edema pilot used 12 weeks. Some metabolic observations persisted four weeks after treatment.

Reference data

Lyophilized vial injectable protocols

Not personalized dosing instructions
