What ARA 290 is
ARA 290 (cibinetide) mimics a surface helix of erythropoietin that is responsible for tissue-protective signalling. It is designed to bind the innate repair receptor, a complex of the EPO receptor and the common beta receptor, without stimulating red blood cell production.
It has been studied in small clinical trials for nerve damage and in preclinical models of inflammation and tissue injury. Published human data remain limited and have come from early-phase studies.
What the research literature studies
- Innate repair receptor binding and signalling in cell models
- Inflammation and tissue-injury models in rodents
- Structure-activity work on erythropoietin-derived helix peptides
Evidence rating: 3/5
Early human trials. Small early-phase human trials and preclinical models. Not approved. See our methodology for how levels are assigned.
- Human trials have been small and early-phase, so effect sizes are uncertain.
- Stability in circulation is short for an unmodified 11-residue peptide.
Regulatory status
ARA 290 has not been approved by any regulator, including the MHRA, EMA and FDA. Research material must not be used in people or animals.

ARA 290 FAQ
Is ARA 290 the same as erythropoietin?
No. It is a short peptide designed to reproduce only the tissue-protective part of the hormone, not its effect on red blood cell production.
Is cibinetide the same as ARA 290?
Yes. Cibinetide is the international nonproprietary name for ARA 290.
Where can I buy ARA 290 for research?
Nordapep does not currently list ARA 290. You can ask Nordapep about availability, or compare related compounds that are in stock.
Is ARA 290 approved?
ARA 290 has not been approved by any regulator, including the MHRA, EMA and FDA. Research material must not be used in people or animals.
