METHOD OF USING A RET FUSION GENE AS A BIOMARKER TO SELECT NON SMALL CELL LUNG CANCER (NSCLC) AND THYROID CANCER PATIENTS FOR A CANCER TREATMENT

摘要

The present invention relates to a RET fusion gene such as a CCDC6-RET fusion gene as a biomarker to monitor the activity of the compound 3-Z-[1-(4-(N-((4-methyl-piperazin-1-yl)-methylcarbonyl)-N-methyl-amino)-anilino)-1-phenyl-methylene]-6-methoxycarbonyl-2-indolinone or a pharmaceutically acceptable salt thereof, and especially its monoethanesulphonate salt form, when used alone or optionally in combination with further pharmaceutically active ingredients and/or further treatments. The present invention also relates to specific uses of said specific compound in the treatment of cancers.
