AZD-1981, developed by AstraZeneca, is a potent (binding IC50 of 4nM), fully reversible, functionally non-competitive antagonist of human CRTh2. It blocks agonist-induced human eosinophil CD11b expression, shape change (including in whole blood), and chemotaxis as well as an basophil shape change and Th2-cell chemotaxis at IC50's of 8.5-50nM. Potency is similar across species as is plasma protein binding (~97%). AZD-1981 is a weak (10s of μM) inhibitor in vitro of CYP2C9, OATP1B1 and UGT1A1 as well as an inducer of CYP3A4. AZD-1981 was well tolerated and no safety concerns were identified.There was no beneficial clinical effect of AZD-1981, at a dose of 1000 mg twice daily for 4 weeks, in patients with moderate to severe COPD. AZD-1981 has being discontinued for asthma and chronic obstructive pulmonary disease. AstraZeneca is collaborating with Johns Hopkins University for the development of AZD-1981 in the treatment of chronic idiopathic urticaria. It is in phase II clinicals studies for the treatment of Urticaria.
