Used in the treatment of advanced solid tumors, particularly in clinical studies for non-small cell lung cancer and thyroid cancer. It functions as a selective inhibitor of vascular endothelial growth factor receptors (VEGFR), platelet-derived growth factor receptor (PDGFR), and Kit, which are involved in tumor angiogenesis and growth. By blocking these receptors, it helps suppress the formation of new blood vessels that support tumor progression. Investigated in combination with other anticancer agents to enhance therapeutic efficacy.
