Clinical trial: Brigatinib in Treating Patients With ALK and ROS1 Gene Alterations and Locally Advanced or Metastatic Solid Cancers

Summary: This phase II trial studies how well brigatinib works in treating patients with ALK and ROS1 gene alterations and solid cancers that have spread to nearby tissue and lymph nodes or other places in the body. Brigatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed description: PRIMARY OBJECTIVES:
  I. To evaluate the overall response rate (ORR) of brigatinib in patients with advanced solid tumors harboring genomic alterations in ALK (excluding lung) and ROS1 (all solid tumors).
  SECONDARY OBJECTIVES:
  I. To assess the safety and tolerability of brigatinib in patients with advanced solid tumors harboring genomic alterations in ALK (excluding lung) and ROS1 (all solid tumors).
  II. To assess progression free survival (PFS) and overall survival (OS) in patients with advanced ALK or ROS1 mutated solid tumors treated with brigatinib.
  III. To assess sensitivity and durability of response to brigatinib in different solid tumor types.
  IV. To assess the role of intertumoral and intratumoral heterogeneity in the development of resistance to brigatinib.
  V. To identify candidate genomic (including circulating tumor deoxyribonucleic acid [DNA]) and proteomic biomarkers of tumor sensitivity and resistance to brigatinib using high-throughput approaches (exome, transcriptome, reverse phase protein array [RPPA]).
  TERTIARY OBJECTIVES:
  I. Correlation of brigatinib exposure with efficacy and safety. II. Correlation of tumor and plasma biomarkers with brigatinib efficacy and safety.
  OUTLINE:
  Patients receive brigatinib orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
  After completion of study treatment, patients are followed up every 3 months for 52 weeks.

Eligibility: Inclusion Criteria:
  -  Patients with histologically or cytologically confirmed diagnosis of locally advanced or metastatic solid tumors
  -  Patients must have activating genomic alterations in ALK or ROS1 (mutations, fusions or amplifications) by any validated Clinical Laboratory Improvement Act (CLIA)-certified molecular testing (fluorescence in situ hybridization [FISH], polymerase chain reaction [PCR] or next-generation sequencing [NGS] data are acceptable); CLIA validated results from other institutions and commercial diagnostic labs (e.g. Foundation Medicine) are also acceptable
  -  Patients with progressive disease on any previous therapy including crizotinib and other ALK tyrosine kinase inhibitors (TKIs), chemotherapy or immunotherapy

  -  Patients with tumor suitable for biopsy (as assessed by trained specialists in interventional radiology) and medically fit to undergo a biopsy or surgical procedure will have mandatory pre-treatment tumor biopsy or sampling; however, if patients do not have a tumor suitable for biopsy but have another tissue (preferably progressive metastatic site) available for molecular evaluation this will be acceptable
  -  Patients with solid tumors must have at least 1 measurable lesion per Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1; Note: previously irradiated lesions may not be used for target lesions; unless there is unambiguous radiological progression after radiotherapy; brain lesions may not be used as target lesions if they were: 1) previously treated with whole brain radiation therapy (WBRT) within 3 months, or 2) previously treated by stereotactic radiosurgery (SRS) or surgical resection

  -  Total bilirubin =< 1.5 x upper limit of normal (ULN), unless due to Gilbert?s syndrome (< 5 if metastatic involvement of the liver)
  -  Serum lipase =< 1.5 x ULN
  -  Serum amylase =< 1.5 x ULN
  -  Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/ alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional ULN
  -  Left ventricular ejection fraction (LVEF) >= 50% by echocardiogram or multi-gated acquisition (MUGA)
  -  Normal QT interval on screening electrocardiogram (ECG), defined as QT interval corrected of =< 450 ms in males or =< 470 ms in females
  -  Serum creatinine =< 1.5 mg/dL OR calculated creatinine clearance (Cockroft-Gault formula) >= 60 mL/min OR 24-hour urine creatinine clearance >= 60 mL/min
  -  Ability to understand and the willingness to sign a written informed consent document
  Exclusion Criteria:
