Summary
This National Cancer Institute (NCI)-NRG ALK Protocol phase II trial studies how well a combination of different biomarker/ALK inhibitors work in treating patients with stage IV ALK positive non-squamous non-small cell lung cancer. Lorlatinib, ceritinib, alectinib, brigatinib, ensartinib, and crizotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as pemetrexed, cisplatin, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether a combination of biomarker/ALK inhibitors or chemotherapy may work better in treating patients with ALK positive non-squamous non-small cell lung cancer.
