Summary

This phase III trial compares the effect of bevacizumab and osimertinib combination vs. osimertinib alone for the treatment of non-small cell lung cancer that has spread outside of the lungs (stage IIIB-IV) and has a change (mutation) in a gene called EGFR. The EGFR protein is involved in cell signaling pathways that control cell division and survival. Sometimes, mutations in the EGFR gene cause EGFR proteins to be made in higher than normal amounts on some types of cancer cells. This causes cancer cells to divide more rapidly. Osimertinib may stop the growth of tumor cells by blocking EGFR that is needed for cell growth in this type of cancer. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. Giving osimertinib with bevacizumab may control cancer for longer and help patients live longer as compared to osimertinib alone.

Objectives

PRIMARY OBJECTIVE:
I. To evaluate progression-free survival (PFS) of osimertinib (AZD9291) and bevacizumab versus osimertinib (AZD9291) alone as first-line treatment for patients with metastatic EGFR-mutant lung cancers.

SECONDARY OBJECTIVES:
I. To evaluate overall survival (OS).
II. To evaluate best objective response rate and duration of objective response.
III. To evaluate time to central nervous system (CNS) progression and CNS PFS.
IV. To evaluate toxicity of the combination regimen.

CORRELATIVE OBJECTIVES:
I. To characterize mechanisms of resistance to osimertinib (AZD9291) and osimertinib (AZD9291) with bevacizumab first-line therapy through post-progression circulating tumor-derived deoxyribonucleic acid (ctDNA).
II. To assess for ctDNA clearance on study treatment and associate ctDNA clearance with clinical outcomes.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM A: Patients receive osimertinib orally (PO) once daily (QD) on days 1-21. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

ARM B: Patients receive osimertinib PO QD on days 1-21 and bevacizumab intravenously (IV) over 30-90 minutes on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Patients undergo echocardiography (ECHO), multigated acquisition scan (MUGA), computed tomography (CT) and may undergo magnetic resonance imaging (MRI) and blood sample collection on study.

After completion of study treatment, patients are followed up every 3 months for 10 years.

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments.
