CP-195543 is a selective and potent leukotriene B4 (LTB4) receptor antagonist developed by Pfizer. CP-195543 inhibited human and mouse neutrophil chemotaxis mediated by LTB4. In vivo, after oral administration, CP-195543 blocked LTB4-mediated neutrophil infiltration in guinea pig and murine skin. CP-195543 reduced the clinical symptoms and attendant weight loss in an IL-1-exacerbated murine model of collagen-induced arthritis. Combination of CP-195543 and celecoxib was investigated in phase 2 clinical trials against rheumatoid arthritis, but the drug failed to achieve superiority over placebo, and its development was discontinued.
