ARA-290 (Cibinetide)

Cibinetide, ARA290, ARA 290, Helix B surface peptide

11-amino-acid peptide derived from erythropoietin that activates the innate repair receptor for tissue protection without stimulating red blood cell production. Holds FDA orphan status for sarcoidosis and islet-transplant survival; completed a Phase 2 trial in diabetic macular edema, with preclinical work in neuropathy, Alzheimer’s, and drug-induced kidney injury.

Research score 70/100. Reference only, not a dose.

Approval
Phase 2 Clinical Trial (Completed). Granted orphan drug designation for sarcoidosis and pancreatic islet transplantation.
Evidence
Phase 2 clinical trial for Diabetic Macular Edema completed. Extensive preclinical research shows neuroprotection, organ protection (e.g., against cisplatin-induced nephrotoxicity, 2022), and potential to ameliorate frailty in mouse models.

Mechanism

Binds the innate repair receptor (a CD131/EPOR-beta complex), triggering JAK2/STAT3 and PI3K/Akt signaling that protects nerve tissue from apoptosis, curbs inflammation, and supports nerve regeneration and pain reduction.

Safety file

Generally well tolerated in trials, with mild, transient side effects.

  • Injection site reactions
  • Mild headache
  • Temporary dizziness
