Additional Information

directly inhibited LPS-induced IL-6 production from RPMI-8226 (IC50 = 100 pM) in vitro. In SCID-beige mice, LPS (3 μg/kg) induced IL-6 (7897 ± 827 pg/mL) and TNF-alpha (1922 ± 282 pg/mL) after 2 hours and these cytokines were inhibited by oral administration of ARRY-797 (30 mg/kg) by 91% and 95%, respectively. In MM xenograft models, ARRY-797 (30 mg/kg, BID, PO) inhibited RPMI 8226 tumor growth by 72% as a single agent and by 56% when LPS was administered to stimulate growth in vivo. In addition, ARRY-797 inhibited LPS-induced phosphorylation of p38 in RPMI-8226 xenografts. Together, these data support a role for p38 in IL-6-mediated growth of multiple myelomas. ARRY-797 is the first small molecule p38 inhibitor to demonstrate single agent activity in a MM xenograft model and it has been advanced into preclinical development.
