In this research study, the investigators are using the study drug called Capmatinib. Capmatinib is a specific blocker of the cMET protein. This protein acts as a trigger to start a series of events in your cells in what is known as the C-Met pathway. Patients with MET exon 14 skipping have activation of the MET pathway. By blocking MET, Capmatinib may slow or stop the growth and/or survival of cancer cells. Capmatinib is not yet FDA approved for the treatment of people with this type of cancer. It is not known if capmatinib will be effective in people who have previously had other drugs that block the cMET pathway. This study will help us understand how capmatinib works in the body and what capmatinib does to cancer. Any potential harmful effects of capmatinib will also be studied.
