About

This early phase I trial studies the side effects and how well local consolidative therapy (LCT) and brigatinib works in treating patients with non-small cell lung cancer that is stage IV or has come back (recurrent). Giving LCT, such as surgery and/or radiation, after initial treatment may kill any remaining tumor cells. Brigatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving LCT and brigatinib may work better in treating patients with non-small cell lung cancer.

Full description

PRIMARY OBJECTIVES:

I. To assess the safety, tolerability, and feasibility of brigatinib with local consolidative therapy (LCT) in tyrosine kinase inhibitor-naive ALK-rearranged advanced (non-small cell lung cancer) NSCLC.

SECONDARY OBJECTIVES:

I. To determine progression-free survival (PFS) using modified Response Evaluation Criteria in Solid Tumors (RECIST 1.1) in advanced ALK+ NSCLC patients treated with local consolidative therapy (LCT) after achieving stable disease or partial response with first-line brigatinib treatment.

II. To determine overall survival (OS).

III. To assess time to progression (TTP) of non-LCT lesions.

EXPLORATORY OBJECTIVES:

I. To assess time to appearance of new metastatic lesion(s).

II. To determine the utility of pre-treatment, pre-LCT, and post-LCT circulating free tumor deoxyribonucleic acid (DNA) (cfDNA) as a potential prognostic and predictive biomarkers.

II. To evaluate potential impact of LCT on mechanisms of ALK resistance with molecular analysis of post-progression biopsies.

OUTLINE:

Patients receive brigatinib orally (PO) once daily (QD) on days 1-28. Treatment repeats every 28 days for up to 2 courses in the absence of disease progression or unacceptable toxicity. Patients then undergo LCT for up to 3 weeks in the absence of disease progression or unacceptable toxicity. Within 7 days after completion of LCT, patients receive brigatinib PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and every 3 months for up to 2 years.

Enrollment: 35 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

   2. Are surgically sterile, OR
   3. If they are of childbearing potential, agree to use a highly effective method of contraception from the time of signing the informed consent through 4 months after the last dose of study drug, or agree to completely abstain from heterosexual intercourse
