MedKoo CAT#: 203186

CAS#: 781613-23-8

Description: Tesevatinib, also known as XL647, EXEL-7647 and KD-019, is a n orally bioavailable small-molecule receptor tyrosine kinase (RTK) inhibitor with potential antineoplastic activity. XL647 binds to and inhibits several tyrosine receptor kinases that play major roles in tumor cell proliferation and tumor vascularization, including epidermal growth factor receptor (EGFR; ERBB1), epidermal growth factor receptor 2 (HER2; ERBB2), vascular endothelial growth factor receptor (VEGFR), and ephrin B4 (EphB4). This may result in the inhibition of tumor growth and angiogenesis, and tumor regression.

Additional Information

Phase II study of XL647: Forty-one patients were enrolled; 33 were evaluable for efficacy. One partial response was observed (response rate 3% and 90% confidence interval, 0% to 14%). Of patients whose tumors harbored T790M, 67% (8/12) had progression of disease as best response compared with 14% (3/21) of those without this mutation. Plasma samples from 40 patients were available for mutation testing, 14 (35%) of which were found to have EGFR mutations. CONCLUSIONS:  The 3% response rate observed did not meet the prespecified threshold to recommend further study of XL647 in patients who develop acquired resistance to erlotinib or gefitinib. Patients with T790M had a significantly worse progression-free survival.   (source: J Thorac Oncol. 2012 Jan;7(1):219-26.)
