Description: Setipiprant, also known as ACT-129968 and KYTH-105, is a potent and selective CRTH2 antagonist. Setipiprant at multiple oral doses was well tolerated and reduced both the allergen-induced LAR and the associated AHR in allergic asthmatics. Setipiprant may be a promising target for the treatment of allergic disorders.
