ARA-290 (a.ka. Cibinetide) is a synthetic peptide developed by Araim Pharmaceuticals that consists of 11 amino acids and is entirely derived from the helix beta domain of erythropoietin (EPO).

And in case you don’t know the role of EPO in your body:

“Erythropoietin (EPO) is a glycoprotein hormone, naturally produced by the peritubular cells of the kidney, that stimulates red blood cell production. EPO production also occurs in the spleen, liver, bone marrow, lung, and brain in small quantities.”

If you look up what ARA-290 is most commonly used for, you’ll notice the disease state known as “sarcoidosis”
