Randomized Controlled Trial Multicenter Study
Setipiprant, a selective CRTH2 antagonist, reduces allergen-induced airway responses in allergic asthmatics.
CRTH2 is a G-protein-coupled receptor on T helper2 cells that mediates pro-inflammatory effects of prostaglandin D2 in allergic responses. ⋯ Setipiprant at multiple oral doses was well tolerated and reduced both the allergen-induced LAR and the associated AHR in allergic asthmatics. Our findings confirm that CRTH2 may be a promising target for the treatment of allergic disorders.
