Vidupiprant, also known as AMG 853, is an orally bioavailable and potent dual antagonist of the D-prostanoid and chemoattractant receptor-homologous molecule expressed on T helper 2 cells receptors. Vidupiprant inhibits PGD2-induced down modulation of CRTH2 on CD16- granulocytes in human whole blood as well as PGD2-induced cAMP response in platelets. It inhibits PGD2-induced airway constriction in vivo. Also inhibits BRD4 (Kd = 170 nM). AMG 853 as an add-on to inhaled corticosteroid therapy demonstrated no associated risks but was not effective at improving asthma symptoms or lung function in patients with inadequately controlled moderate-to-severe asthma. AMG 853 has been discontinued due to poor efficacy.

Sample Use Guides

In Vivo Use Guide

Adults with moderate-to-severe asthma were randomized to placebo; 5, 25, or 100 mg of oral Vidupiprant (AMG 853) twice daily; or 200 mg of AMG 853 once daily for 12 weeks.

Route of Administration: Oral

In Vitro Use Guide

Vidupiprant inhibited the full-length calpain-1 complex with a high potency (IC50 = 7.5 uM). Vidupiprant is a potent dual CRTH2 and prostaglandin D2 (PGD2) receptor antagonist (IC50 values are 8 and 35 nM, respectively in plasma).
