ARA-290, also known as Cibinetide, is an 11-amino-acid synthetic peptide modeled after a specific region of erythropoietin (EPO). It was designed to investigate the tissue-protective properties associated with EPO while avoiding its conventional effects on red blood cell production.
ARA-290 has been studied for its interaction with the proposed innate repair receptor (IRR), a signaling pathway associated with cellular protection, inflammatory regulation, and tissue responses to injury. Its unique research profile has generated interest in neurological research, small-fiber nerve function, and cellular recovery.

Where the interest is
– Nerve health research: Clinical studies have investigated ARA-290 in relation to small-fiber neuropathy, particularly nerve-related symptoms associated with sarcoidosis.
– Inflammatory signaling: Research focuses on its potential influence on inflammatory pathways and cellular responses to tissue stress.
– Tissue protection: Researchers are investigating its relationship with cellular survival, tissue integrity, and protective mechanisms involving the proposed innate repair receptor.
What to expect
ARA-290 is an investigational research peptide with some early human clinical research, including small Phase II studies. These studies have explored its potential effects on small-fiber neuropathy and related neurological measurements. However, the available evidence remains limited, and larger independent clinical trials are needed to establish its effectiveness and safety.
Peptide Evidence Registry+2
Although early findings have generated scientific interest, ARA-290 is not an approved medicine for routine clinical use. Its long-term safety, appropriate clinical applications, and effectiveness across different conditions remain insufficiently established. Research involving ARA-290 should not be interpreted as a guarantee of therapeutic benefits or as a replacement for approved medical care.
