CCX025 is a potent inhibitor of T-cell migration. Increasing concentrations of CCX025 inhibit the chemotaxis of Molt-4 T-cells which constitutively express human CCR9, to human CCL25 in an in vitro migration assay. CCX025 was potent when the assay was run in buffer (a) or in 100% human serum (b). CCX025 inhibits the in vitro chemotaxis of primary mouse thymocytes to murine CCL25 (c). In an in vivo T-cell trafficking model in mice, CCX025 inhibited the recruitment of CD8+ T-cells to the small intestine of OT-1 mice given an oral challenge of ovalbumin (d)
