Targeted Treatment for Advanced Non-Small Cell Lung Cancer That Has a MET Exon 14 Skipping Gene Change (An Expanded Lung-MAP Treatment Trial)

Inclusion Criteria: * Participants must have been assigned to S1900K by the Southwest Oncology Group (SWOG) Statistics and Data Management Center (SDMC). Assignment to S1900K is determined by the LUNGMAP protocol * Participants must have documentation of stage IV or recurrent NSCLC with a MET exon 14 skipping mutation determined by tissue-based or blood-based (circulating tumor DNA \[ctDNA\]) next generation sequencing (NGS) assay done within a laboratory with Clinical Laboratory Improvement Act (CLIA), International Organization for Standardization (ISO)/ International Electrotechnical Commission (IEC), College of American Pathologists (CAP), or similar certification. Documentation must either be: * NGS test results from tissue submitted for LUNGMAP screening, or * Submitted documentation in the LUNGMAP Rave Electronic Data Capture System of a MET exon 14 skipping mutation from a previously completed tissue or blood-based NGS test * Participants must have measurable disease documented by CT or MRI. The CT from a combined positron emission tomography (PET)/CT may be used to document measurable disease ONLY if it is of diagnostic quality, otherwise, it may be used to document non-measurable disease only. Measurable disease must be assessed within 28 days prior to sub-study randomization. Pleural effusions, ascites and laboratory parameters are not acceptable as the only evidence of disease. Non-measurable disease must be assessed within 42 days prior to sub-study randomi…
