Description
Sources: http://adisinsight.springer.com/drugs/800020855
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/17575237

Tesevatinib (EXEL-7647 or XL647) was optimized as an inhibitor of a spectrum of growth-promoting and angiogenic receptor tyrosine kinases (RTKs) to simultaneously block tumor growth and vascularization. In particular, Tesevatinib potently inhibits the EGF/ErbB2, VEGF, and ephrin RTK families. The drug is being developed by Kadmon Corporation under licence from Symphony Evolution (Symphony Capital Partners). Kadmon is developing tesevatinib for the treatment of autosomal polycystic kidney disease and solid cancers.

Sample Use Guides

In Vivo Use Guide

Two dosing schedules were evaluated; in the "intermittent 5 & 9 dosing" cohort, Tesevatinib (XL647) 350 mg for 5 days every 14 days was given; and in the "daily dosing" cohort, XL647 300 mg daily for 28 days was administered. XL647 administered on an intermittent or daily-dosing schedule demonstrated antitumor activity in patients with non-small-cell lung cancer.

Route of Administration: Oral

In Vitro Use Guide

In A431 cells, which express WT EGFR, Tesevatinib reduced cell viability with IC50 values of 13 nmol/L, with 95% confidence intervals of 10 to 15.
