Cơ Chế Tác Dụng :
CHIR-258 is an orally active small molecule that exhibits potent inhibitory activity against multiple RTKs involved in tumor growth and angiogenesis. Preclinical data show that CHIR-258 works to inhibit multiple kinases associated with different cancers, including acute myeloid leukemia (AML) and multiple myeloma. Chiron currently has three ongoing Phase I clinical trials for CHIR-258.
Unlike many kinase inhibitors that only target vascular endothelial growth factor (VEGF), CHIR-258 inhibits receptors in the fibroblast growth factor (FGF ) pathway, as well as VEGF and platelet-derived growth factor (PDGF). FGF receptor tyrosine kinase inhibition is potentially of therapeutic significance to a group of myeloma patients whose cancer cells express high levels of surface FGF receptors.
Chỉ Định :
Investigated for use/treatment in multiple myeloma and solid tumors.
