Assignee: THE GENERAL HOSPITAL CORPORATION (Boston, MA)
Application Number:13/806,929
Patent Claims:1. A method of treating a cancer tumor in a subject in need thereof, comprising: administering an anti-tumor therapy to the subject; and administering a therapeutically effective amount of a CXCR4 inhibitor to the subject within 5 days of administering the anti-tumor therapy; measuring the level of CXCL12 expression in the subject; comparing the level of CXCL12 expression in the subject to a reference level; and administering the CXCR4 inhibitor to the subject until CXCL12 expression is within 10% of the reference level.

7. The method of claim 1, wherein the antitumor therapy comprises administering a VEGF inhibitor.

8. The method of claim 7, wherein the VEGF inhibitor is selected from the group consisting of: ABT-869: AEE-788; AG-13736; AG-028262; Angiostatin; bevacizumab; AVE-8062; AZD-2171; sorafenib; BMS-387032; CEP-7055; CHIR-258; GFKI; CP-547632; CP-564959; E-7080; 786034; GW-654652; IMC-1 C11; KRN-951; PKC-412; PTK-787; SU11248; SU-5416; SU-6668; AVE-0005; thalidomide; XL-647; XL-999; ZD-6474; ZK-304709; Pazopanib; CDP791; Enzastaurin; BIBF 1120; BAY 573952; BAY 734506; XL 184; IMC-1121B; CEP 701; SU 014813; SU 10944; SU 12662; OSI-930; BMS 582664; ZD-6126; Imatinib; STI-571; CGP-57148; RAD-001; BMS-354825; Volociximab; CCI-779; 17-AAG; DMXAA; CI-1040; CI-1033; (5-[5-fluoro-2-oxo-1,2-dihydroindol(3Z)-ylidenemethyl]-2,4-dimethyl-1H-py- rrole-3-carboxylic acid [2-diethylaminoethyl]amide); 4TBPPAPC; AMG 706; and PTK/ZK.
