This phase II trial studies how well osimertinib with or without bevacizumab works in treating patients with EGFR positive non-small cell lung cancer that has spread to the brain. Osimertinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as bevacizumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving osimertinib with or without bevacizumab may work better in treating patients with non-small cell lung cancer.

Description: The two study arms will be compared for PFS with Kaplan-Meier estimates and log-rank tests. The Rothman confidence interval (CI), and the simultaneous confidence bands will be reported. In addition, the possible risk factors will be compared for survival with log-rank test. For multivariate analysis, the proportional hazards Cox model will be applied to investigate potential prognostic factors, such as age and stage of disease of the PFS data. The adjusted p-values of the hazard ratios and the adjusted 95% confidence interval will be reported.
