This phase Ib trial finds the best dose and side effects of ensartinib and its effects when given with carboplatin, pemetrexed and bevacizumab for in treating patients with ALK-positive non-small cell lung cancer that is stage IIIC or IV, or has come back (recurrent). Ensartinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as carboplatin and pemetrexed, 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. Bevacizumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Giving ensartinib, carboplatin, pemetrexed and bevacizumab may help to control the disease.



I. To determine the safety of ensartinib in combination with carboplatin, pemetrexed and bevacizumab in patients with ALK-rearranged advanced non-small cell lung cancer (NSCLC).

II. Determine the recommended phase 2 dose (RP2D) of ensartinib in combination with carboplatin, pemetrexed and bevacizumab.


I. To determine an objective response rate (ORR) in patients with ALK-rearranged advanced NSCLC treated with ensartinib in combination with carboplatin, pemetrexed and bevacizumab using modified Response Evaluation Criteria in Solid Tumors (RECIST 1.1).

II. To determine progression-free survival (PFS). III. To determine overall survival.


I. To determine biomarkers associated with response and resistance to the study combination.

OUTLINE: This is a dose de-escalation study of ensartinib and fixed-dose carboplatin, pemetrexed, and bevacizumab followed by a dose-expansion study.

INDUCTION THERAPY: Patients receive ensartinib orally (PO) once daily (QD) on days 1-21, carboplatin intravenously (IV) over 15-60 minutes on day 1, pemetrexed IV over 10 minutes on day 1 and bevacizumab IV over 30-90 minutes on day 1. Treatment repeats every 21 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity.

MAINTENANCE THERAPY: Patients receive ensartinib PO QD on days 1-21 and bevacizumab IV over 30-90 minutes on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 30 days.
