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

Stage IV Lung Cancer AJCC v8 Clinical Trial

Official title: A Phase 2 Study of Atezolizumab and Cobimetinib in PD-1/PD-L1 Inhibitor Resistant or Refractory Non-Small Cell Lung Cancer

Status Active, not recruiting

Clinical Trial Summary

This phase II trial studies how well atezolizumab and cobimetinib work in treating patients with non-small cell lung cancer that has spread from where it first started (primary site) 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 is used in patients whose cancer has a mutated (changed) form of a gene called BRAF. It is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells. Giving atezolizumab and cobimetinib may work better in treating patients with non-small cell lung cancer.

Clinical Trial Description

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 day 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. Patients also undergo a computed tomography (CT) scan, magnetic resonance imaging (MRI), biopsy, and collection of blood throughout the trial.

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