ARA-290
Also known as: Cibinetide
ARA-290 (Cibinetide) is a synthetic 11-amino-acid peptide derived from the helix-B surface of erythropoietin (EPO), developed by Araim Pharmaceuticals. It selectively activates the innate repair receptor (IRR) for anti-inflammatory, tissue-protective, and neuroprotective signaling without stimulating erythropoiesis. ARA-290 is not FDA-approved; it has received FDA Fast Track and Orphan Drug designations for sarcoidosis-associated small fiber neuropathy and remains in clinical development as of April 2026.

Prices observed from public storefronts (last 24h), normalized to $/mg. "Evidence" is Merit's 0–100 Merit Score, derived only from observable verification evidence (methodology on /about); "Purity" is the latest independent COA. Some buy links are affiliate links — Merit may earn a commission at no extra cost to you, and where a vendor offers one, the code shown gets you a discount at their checkout. Affiliate status never affects price data, ranking, or the Merit Score (full policy on /disclosure). Research use only.
