Summary

This study is to learn if the combination therapy of capmatinib and neritinib can help to control metastatic or locally advanced breast cancer. Researchers also want to find the highest tolerable dose of the combination therapy of capmatinib and neritinib that can be used in this study drug combinations. The safety of this drug combination and the CELsignia MP test methodology will also be studied.
