Trial Summary

What is the purpose of this trial?

The objective of this study is to evaluate the efficacy and safety of oral cabozantinib at a 60 mg dose compared with a 140 mg dose in subjects with progressive, metastatic MTC. It will test if the lower dose results in similar progression free survival (PFS) and overall response rate (ORR) with fewer adverse events compared to the PFS, ORR and adverse events found in previous clinical trials of 140 mg.
