This phase I trial studies the side effects and best dose of brigatinib and binimetinib in treating patients with stage IIIB-IV non-small cell lung cancer and a type of gene mutation called a rearrangement in the ALK or ROS1 genes. Brigatinib and binimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
PRIMARY OBJECTIVES: I. To determine the safety and tolerability of brigatinib in combination with binimetinib in stage IIIB or IV anaplastic lymphoma kinase (ALK) or ROS1 rearranged non-small cell lung cancer (NSCLC) and the recommended phase 2 dose. SECONDARY OBJECTIVES: I. To determine preliminary efficacy of brigatinib in combination with binimetinib in any line of treatment. II. To characterize the pharmacokinetic parameters of brigatinib in combination with binimetinib. EXPLORATORY OBJECTIVES: I. To assess circulating tumor deoxyribonucleic acid (DNA) (ctDNA) utility in evaluating treatment response. II. To evaluate the blockade of downstream signaling indicating response or resistance to treatment of immunohistochemistry (IHC) for phosphatidylinositol 3-kinase (PI3K)/Protein kinase B (AKT)/Mitogen-activated protein kinase (MAPK) pathway activity evaluation. OUTLINE: This a dose-escalation study. Patients receive brigatinib orally (PO) once daily (QD) and binimetinib PO twice daily (BID) 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 for 30 days and then every 6 months for 12 months.

Recommended Phase 2 Dose
Evaluating the number and frequency of adverse events as determined by the National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI-CTCAE) version (v)5.0 by investigator's assessment will be used to determine the recommended phase 2 dose for future studies.
Time frame: Up to 12 months
Number of Participants with Dose Limiting Toxicities
A dose limiting toxicity (DLT) is generally defined as a grade 3 or higher, treatment-related adverse event that is attributable to the study treatment during the first 28 days of therapy (Cycle 1). The dose limiting toxicity will be based on the tolerability observed during cycle 1 of treatment/observation. Adverse events will be assessed by the investigators using NCI-CTCAE v5.0.
Time frame: Up to 28 days
Number of Total Treatment-Emergent Adverse Events (AEs)
Treatment Emergent AEs will be defined by the NCI CTCAE v5.0 as AEs newly occuring after the patient has begun study treatment.
Time frame: From treatment initiation through study completion, an average of 1 year
Number of Treatment-Emergent Adverse Events by Grade
Severity grade will be defined by the NCI CTCAE v5.0.
Time frame: From treatment initiation through study completion, an average of 1 year
Number of Grade 3 or Greater Treatment-Emergent Adverse Events by CTCAE v5.0
Severity grade will be defined by the NCI CTCAE v5.0.
Time frame: From treatment initiation through study completion, an average of 1 year
Number of Serious Treatment-Emergent Adverse Events by CTCAE v5.0
Severity grade will be defined by the NCI CTCAE v5.0.
Time frame: From treatment initiation through study completion, an average of 1 year
Number of Treatment-Emergent Adverse Events with an Outcome of Death by CTCAE v5.0
Severity grade will be defined by the NCI CTCAE v5.0.
Time frame: From treatment initiation through study completion, an average of 1 year
Number of Treatment-Emergent Adverse Events Leading to Discontinuation of Study Treatment
Severity grade will be defined by the NCI CTCAE v5.0.
Time frame: From treatment initiation through study completion, an average of 1 year
Number of Treatment-Emergent Adverse Events Resulting in Interruption, Reduction, or Delay of study treatment
Severity grade will be defined by the NCI CTCAE v5.0.
Time frame: From treatment initiation through study completion, an average of 1 year
Objective Response Rate (ORR) Assessed by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
RECIST v1.1 will be used to determine the overall response rate defined as participants with a complete response (CR) or a partial response (PR). Point estimate and 95% exact binomial confidence interval (CI) will be obtained for ORR.
Time frame: From treatment initiation through study completion, an average of 1 year
Median Depth of Response Assessed by RECIST v1.1
Will be defined as maximal reduction in tumor size based on Response Evaluation Criteria in Solid Tumors (RECIST) measurement. Median and inter-quartile range will be used to describe the depth of response (the maximal reduction in tumor size based on RECIST measurement).
Time frame: From treatment initiation through study completion, an average of 1 year
Area Under the Plasma Concentration versus Time Curve (AUC) of Brigatinib
Plasma concentration assessment (pharmacokinetic data) of brigatinib during coadministration with binimetinib will be determined by assay at various timepoints. The assay will be done by Takeda / their designated vendor.
Time frame: At pre-dose, 0.5, 1, 2, 4, 6, 8 and 24 hours post-dose on days 1 and 15 of cycle 1
Median Progression Free Survival (PFS)
PFS is measured as the time from start of treatment to time of disease progression at 6 months. Kaplan-Meier method will be used to describe the describe the median PFS with 95% CI.
Time frame: Up to 6 months
Median Overall Survival (OS)
Overall Survival is measures as the time from start of treatment to time of death, or lost to follow-up. Kaplan-Meier method will be used to describe the describe the median OS at 12 months with 95% CI.
Time frame: Up to 12 months
