Real-World Assessment of Clinical Outcomes in Metastatic NSCLC Patients With MET Exon 14 Skipping Mutation and Brain Metastases Treated With Capmatinib

This was a retrospective, noninterventional cohort study of patients with a confirmed diagnosis of metastatic NSCLC with MET Exon 14 skipping mutation and brain metastases (BM) who received treatment with capmatinib in real-world practice settings. The study population consisted of patients with histologically confirmed stage IIIB, IIIC, or IV MET Exon 14 skipping mutated NSCLC with BM. The date of the initiation of therapy with capmatinib after the date of initial BM diagnosis at or after the initial advanced or metastatic NSCLC diagnosis defined the study index date. The 12-month period before the study index date defined the baseline period to assess baseline demographic and clinical characteristics. Study measures were assessed at the index and during the baseline and postindex date periods. The index date needed to occur between 1 May 2020 and the date of data abstraction, provided the selected patients meet the requirement of a minimum of 6 months follow-up time available after capmatinib initiation; the exceptions to this are those patients who died during this period.
