ARA-290 (Cibinetide)
ARA-290, also known as Cibinetide, is an 11-amino-acid synthetic peptide derived from the helix B region of human erythropoietin (EPO). Unlike EPO itself, ARA-290 does not affect red blood cell production — it selectively engages the innate repair receptor (IRR), a heteromeric complex of the EPO receptor and CD131. Preclinical and Phase 2 clinical research has explored its effects on neuropathic pain, tissue repair, and inflammatory signaling without the hematopoietic side effects of EPO.
