Discovery of [5-Amino-1-(2-methyl-3<i>H</i>-benzimidazol-5-yl)pyrazol-4-yl]-(1<i>H</i>-indol-2-yl)methanone (CH5183284/Debio 1347), An Orally Available and Selective Fibroblast Growth Factor Receptor (FGFR) Inhibitor
The fibroblastgrowthfactorreceptor (FGFR) family of receptor tyrosine kinases regulates multiple biological processes, such as cell proliferation, migration, apoptosis, and differentiation. Various genetic alterations that drive activation of the receptors and the pathway are associated with tumor growth and survival; therefore, the FGFR family represents an attractive therapeutic target for treating

The present inventors successfully identified novel gatekeeper mutations for FGFR. Further, they discovered that mutant FGFR having the mutations demonstrate resistance to known FGFR inhibitors such as AZD4547, and at the same time demonstrate sensitivity to specific compounds. Mutant polypeptides having the mutations may be used as biomarkers in cancer treatment by FGFR inhibitors to prevent the development of side effects in therapy by conventional FGFR inhibitors, and to control the therapeutic mode for receiving the best therapeutic effect, thus making individualized treatment possible.

The FGFR-encoding gene was studied extensively with regard to its expression, hyperamplification, mutation, translocation, or such in various cancer cells. As a result, novel fusion polypeptides in which the FGFR3 polypeptide is fused with a different polypeptide were identified and isolated from several types of bladder cancer-derived cells and lung cancer cells. The use of a fusion polypeptide of the present invention as a biomarker in FGFR inhibitor-based cancer therapy enables one to avoid side effects in cancer therapy and control the therapeutic condition to produce the best therapeutic effect, thereby enabling individualized medicine.
