ARA-290

InvestigationalModerate Research

Also known as: Cibinetide · Innate Repair Receptor Agonist

A non-erythropoietic EPO-derived peptide that activates the innate repair receptor, providing tissue-protective and anti-inflammatory effects without blood thickening.

Overview

ARA-290 (Cibinetide) is an 11-amino acid peptide derived from the tissue-protective domain of erythropoietin (EPO) that selectively activates the innate repair receptor (IRR). Unlike EPO itself, ARA-290 does not stimulate red blood cell production or cause blood thickening. The innate repair receptor is expressed on a wide variety of tissues and is upregulated during injury and inflammation. When activated by ARA-290, it triggers anti-inflammatory, anti-apoptotic, and tissue-repair signaling cascades.

Clinical trials have demonstrated ARA-290's efficacy in treating small fiber neuropathy, sarcoidosis-related neuropathy, and chronic pain conditions.

Mechanism of Action

Binds to the innate repair receptor (IRR), a heterodimer of EPO-R and beta-cR. Activates JAK2/STAT5, PI3K/Akt, and NF-kB modulation pathways. Reduces pro-inflammatory cytokine production, inhibits apoptosis in stressed cells, promotes angiogenesis, and stimulates tissue repair.

Key Benefits

Neuroprotection and nerve repair
Anti-inflammatory effects
Improved small fiber neuropathy symptoms
Tissue repair and wound healing
