This trial is a phase II, two cohort study of neoadjuvant capmatinib treatment (pre-surgery) which will be given for 8 weeks prior to a surgical resection and then followed by a three year adjuvant capmatinib treatment (post surgery). Following treatment, there will be a two year survival follow-up. The two molecularly defined cohorts will be enrolled in parallel. Approximately 38 evaluable participants will be enrolled in the study.~During treatment participants will visit their treating physician to assess overall health status which will include lab-work and other safety assessments. Survival follow-up will be every 6 months which can be conducted via a telephone visit for up to approximately 2 years after end of treatment.
The purpose of this study is to determine if neoadjuvant capmatinib can improve outcomes in participants with stages I-IIIA non-small cell lung cancer with MET exon 14 mutations and/or high MET amplification beyond those achieved with surgery, chemotherapy, and radiation.
