METBEIGE biomarker study

Intervention name : Cabozantinib Malate
INN of the intervention : Cabozantinib
Dosage And administration of the intervention : Cabozantinib (administered in the main study): 40 mg or 60 mg, once daily at bedtime, oral, in a 28 day-course.
Control intervention name : -
INN of the control intervention : -
Dosage And administration of the control intervention : -
Primary outcome(s): pharmacogenomics
Analyses will be performed of the following parameters using formalin-fixed and paraffin-embedded (FFPE) specimens and freshly frozen specimens prepared from tumor tissue collected for the METBEIGE study (before protocol treatment, before the start of the second cycle, and after discontinuation of protocol treatment) and blood specimens collected at the same time.
The results obtained from the analyses will be integrated with clinical data obtained in the METBEIGE study to identify biomarkers of the effectiveness of the protocol treatment.
1)Analysis of cancer-related genetic abnormalities
