About Epeleuton
Epeleuton is 15-hydroxy eicosapentaenoic acid (15(S)-HEPE) ethyl ester, a novel synthetic fatty acid oral drug product. Epeleuton has been shown to have a unique mechanism of action for the treatment of SCD, targeting factors affecting severity, course of disease, and vaso-occlusive crisis risk.
Afimmune is developing Epeleuton for SCD due to its novel disease-modifying effects and first-in-class opportunity. Epeleuton has received orphan drug designation for the treatment of SCD from the FDA and the EMA, in addition to rare pediatric disease and fast track designations from the FDA.
About Sickle Cell Disease
SCD is a group of inherited, progressive blood disorders carried by the β allele of the hemoglobin gene with an expected 30-year reduced life expectancy. The disease is characterized by abnormal polymerization of hemoglobin during oxygenation which results in the sickling of red blood cells. The disease is rare, with an estimated prevalence of only ~100,000 people affected in the US and ~52,000 people in Europe.
About Afimmune
Afimmune, headquartered in Dublin, Ireland, is a clinical stage drug discovery and development company working on new medicines to improve the quality of life for people with rare diseases.
