Lung Cancer Clinical Trial

Atezolizumab and Cobimetinib in Treating Patients With Metastatic, Recurrent, or Refractory Non-small Cell Lung Cancer

Summary

This phase II trial studies how well atezolizumab and cobimetinib work in treating patients with non-small cell lung cancer that has spread to other places in the body (metastatic), has come back (recurrent), or does not respond to treatment (refractory). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cobimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving atezolizumab and cobimetinib may work better in treating patients with non-small cell lung cancer.

PRIMARY OBJECTIVE:

I. To evaluate durable overall response rate with atezolizumab plus cobimetinib in patients with metastatic non-small cell lung cancer (NSCLC) resistant or refractory to prior PD-1 or PD-L1 therapy.

SECONDARY OBJECTIVES:

I. To evaluate the overall response rate of atezolizumab plus cobimetinib in patients with metastatic NSCLC resistant or refractory to prior PD-1 or PD-L1 therapy.

II. To evaluate the progression-free survival (PFS) of atezolizumab plus cobimetinib in patients with metastatic NSCLC resistant or refractory to prior PD-1 or PD-L1 therapy.

III. To evaluate the overall survival (OS) of atezolizumab plus cobimetinib in patients with metastatic NSCLC resistant or refractory to prior PD-1 or PD-L1 therapy.

IV. To evaluate the duration of response (DOR) of atezolizumab plus cobimetinib in patients with metastatic NSCLC resistant or refractory to prior PD-1 or PD-L1 therapy.

V. To evaluate the grade 3 and 4 toxicity rate in patients with metastatic NSCLC resistant or refractory to prior PD-1 or PD-L1 therapy when treated with atezolizumab plus cobimetinib.

EXPLORATORY OBJECTIVES:

I. To evaluate the consequences of treatment with atezolizumab plus cobimetinib on the tumor microenvironment in patients with metastatic NSCLC resistant or refractory to prior PD-1 or PD-L1 therapy.

II. To correlate genomic characteristics including tumor mutation burden to response to therapy with atezolizumab plus cobimetinib in patients with metastatic NSCLC resistant or refractory to prior PD-1 or PD-L1 therapy.

OUTLINE:

Patients receive atezolizumab intravenously (IV) over 30-60 minutes on days 1, and cobimetinib orally (PO) once daily (QD) on days 1-21. Cycles repeat every 28 days in the absence of disease progression or unaccepted toxicity.

After completion of study treatment, patients are followed up for 90 days.
