Overview

What is Ara 290?

Ara 290 (Cibinetide) is an engineered 11-amino acid peptide derived from erythropoietin that activates the Innate Repair Receptor (IRR) to provide tissue-protective effects without stimulating red blood cell production. It has completed multiple Phase 2 clinical trials and holds FDA Orphan Drug status for several indications.

Key Benefits

Proven tissue protection, nerve regeneration (23% increase in corneal nerve fibers), anti-inflammatory effects, excellent safety profile in clinical trials, no erythropoietic effects.

Mechanism of Action

Activates Innate Repair Receptor (IRR) through EPOR/β-common receptor complex, triggering tissue-protective signaling without erythropoietic effects.

Timing: Morning administration may optimize circadian alignment with tissue repair. Short half-life but triggers long-lasting cellular effects.

Peptide Interactions

How to Reconstitute

Important: Always use bacteriostatic water (BAC). Sterile technique is essential.

1

Allow vial to reach room temp

2

Clean vial top with alcohol

3

Slowly inject 1 mL sterile water

4

Gently swirl to dissolve

5

Solution may be slightly cloudy - normal

6

Use immediately or refrigerate up to 24 hours
