ARA-290, also known by the generic name cibinetide, is a synthetic peptide made of 11 amino acids. It is based on a small part of erythropoietin (EPO), the hormone that signals the body to make red blood cells.
Unlike EPO, ARA-290 was designed so that it does not stimulate red blood cell production. Instead, it was built to act on a different receptor complex involved in tissue protection and inflammation.
Cibinetide has been studied in clinical trials for small fiber neuropathy, a type of nerve damage, in people with sarcoidosis.
Current status: Investigational – not FDA-approved.
Investigational means ARA-290 has been tested in clinical research but has not been approved by the FDA. It is not available as a prescription medicine in the United States.
