Osimertinib With or Without Bevacizumab in Treating Patients With EGFR Positive Non-small Cell Lung Cancer and Brain Metastases
Does targeted therapy with or without immunotherapy work better in treating patients with non-small cell lung cancer?
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.
A Phase II Trial of AZD9291 (Osimertinib) With or Without Bevacizumab in Patients With EGFR Mutation Positive NSCLC and Brain Metastases
- To determine the progression-free survival with AZD9291 (osimertinib) plus bevacizumab compared to AZD9291 (osimertinib) alone.
- To assess the safety and tolerability of the combination of AZD9291 (osimertinib) and bevacizumab.
II. To evaluate the time to progression in the central nervous system (CNS) with AZD9291 (osimertinib) plus bevacizumab versus single-agent osimertinib.
III. To determine the overall response rate and the intracranial response rate to the combination versus single agent.
IV. To assess the overall survival in patients receiving AZD9291 (osimertinib) plus bevacizumab compared to AZD9291 (osimertinib) alone.
- To investigate mechanisms of sensitivity and resistance to combination AZD9291 (osimertinib) plus bevacizumab versus AZD9291 (osimertinib) by molecularly characterizing tumor samples including T790M status.
II. To assess whether circulating tumor deoxyribonucleic acid (DNA) in plasma can be used as an indicator of sensitivity and resistance to treatment.
III. To determine whether an angiogenic signature using a multiplex panel array is associated with benefit from the combination of AZD9291 (osimertinib) plus bevacizumab.
IV. To investigate angiogenesis, immune and signaling pathway markers in tumor samples to determine biomarkers predictive of benefit from combination therapy.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive osimertinib orally (PO) once daily (QD) on days 1-21 and bevacizumab intravenously (IV) over 30-90 minutes on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive osimertinib PO QD on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for a minimum of 4 weeks.

- Patients are not required to have measurable systemic (i.e. non-CNS) disease; if present, measurable systemic disease must be able to be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as >= 20 mm (>= 2 cm) with conventional techniques or as >= 10 mm (>= 1 cm) with spiral computed tomography (CT) scan, MRI, or calipers by clinical exam
