How ARA-290 Works (Mechanisms of Action)
1. Activates the Innate Repair Receptor (IRR)
ARA-290 selectively activates the innate repair receptor, a protective signalling complex derived from erythropoietin biology that promotes tissue repair without stimulating red blood cell production.
This receptor is responsible for:
Cellular protection during inflammation
Tissue repair signalling
Immune modulation
2. Supports Small-Fiber Nerve Repair
ARA-290 has been studied in human clinical trials for small-fiber neuropathy, with outcomes including:
Improved corneal nerve fibre density
Reduced neuropathic pain symptoms
Improved nerve function biomarkers
Corneal nerve fibre density is a validated surrogate for small-fiber nerve health.
3. Modulates Inflammatory Cytokines
ARA-290 reduces harmful inflammation by regulating cytokine activity involved in chronic pain and nerve irritation, including:
TNF-α
IL-6
Other pro-inflammatory mediators
This allows inflammation to settle without suppressing the immune system.
4. Provides Tissue-Protective Signalling
ARA-290 enhances cell survival pathways in stressed tissues, protecting nerves and surrounding structures from inflammatory and metabolic damage.
5. Avoids Erythropoiesis & Hormonal Disruption
Unlike erythropoietin (EPO), ARA-290:
Does not increase red blood cell count
Does not alter blood viscosity
Does not affect haemoglobin levels
This significantly improves its safety profile.
What Is ARA-290 (Cibinetide)?
ARA-290 (also known as Cibinetide) is a synthetic peptide designed to activate the body’s innate repair receptor (IRR) — a protective signalling complex that triggers tissue repair, immune modulation, and anti-inflammatory responses without increasing red blood cell production like erythropoietin.
It is among the few peptides with human clinical trial evidence, particularly in treating small-fiber neuropathy in diseases such as sarcoidosis — with objective improvements in nerve fibre metrics and patient-reported neuropathic symptoms.
