Brief Summary:
This is a single arm phase II study of brigatinib alone for patients with brain metastases from anaplastic lymphoma kinase (ALK) positive non-small cell lung cancer (NSCLC), who have either not been treated previously with a tyrosine kinase inhibitor (TKI) targeting ALK or who have had prior exposure to crizotinib.

Condition or disease Intervention/treatment Phase
Brain Metastases Lung Cancer Drug: Brigatinib Phase 2

Detailed Description:
In this single-arm phase II trial, patients with brain metastases from ALK+ NSCLC will be treated with brigatinib alone without upfront brain irradiation. Patients will have close monitoring with clinical follow up visits and brain magnetic resonance imaging (MRI) surveillance, which will maximize safety and allow for early treatment if disease progression is observed. If brigatinib alone can demonstrate high rates of CNS disease control, these data could support a strategy of upfront brigatinib alone for carefully selected patients with brain metastases from ALK+ NSCLC.

Arm Intervention/treatment
Experimental: Patients with ALK+ NSCLC and brain metastases
Including patients with brain metastases from ALK (anaplastic lymphoma kinase) positive NSCLC (non-small cell lung cancer), who are either neurologically asymptomatic or who have only mild neurologic symptoms (RTOG [Radiation therapy Oncology Group] acute neurologic morbidity score 0-2) from their brain metastases, who are TKI (tyrosine kinase inhibitor) naïve or who have had prior exposure to crizotinib, but who are naïve to brigatinib and other ALK TKIs including alectinib, lorlatinib, and ceritinib.
Drug: Brigatinib
At day 1, all patients will be started on brigatinib 90 mg daily for 7 days, before escalating to 180 mg daily thereafter as tolerated.

Primary Outcome Measures :

  3. Time Until Progression With Brigatinib Alone (Part 3) [ Time Frame: up to 24 months ]
    Time until any distant brain PD (i.e., new brain lesions that were not present at the time of enrollment) by RANO-BM criteria and rates at follow up intervals

  4. Time Until Progression With Brigatinib Alone (Part 4) [ Time Frame: up to 24 months ]
    Time until progression at any site using RANO-BM for intracranial disease and RECIST for extracranial disease and rates at follow up intervals

  9. Longitudinal Changes in Quality of Life With Brigatinib Alone [ Time Frame: up to 24 months ]
    Quality of life will be assessed using standardized QOL metrics (EORTC QLQ C30/BN 20)

Other Outcome Measures:
  1. Analysis of Blood at Baseline and at Progression to Correlate With Clinical Outcomes [ Time Frame: up to 24 months ]
    Evaluation of cfDNA at baseline and progression to correlate with clinical outcomes, including incidence of disease recurrence per RANO-BM and RECIST 1.1, survival status by percentage of patients alive at 2 years, and patient rating of quality of life per EORTC QLQ-BN20 and EORTC QLQ-C30 questionnaires.

  2. Characterization of Corticosteroid Administration Before and After Brigatinib Initiation [ Time Frame: up to 24 months ]
    Quantification of the agent and dosage of corticosteroids at each study assessment

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Provision to sign and date the consent form.
  2. Stated willingness to comply with all study procedures and be available for the duration of the study.
  3. Ability to take and retain oral medications.
  4. Age ≥18 years.
  5. Patients with ALK+ lung cancer with evidence of ≥1 previously untreated brain metastases on brain MRI. Prior therapy (radiation or surgery) for brain metastases is allowed. However, patients must have ≥1 previously untreated at the time of enrollment.
  6. Patients may be ALK TKI naïve OR have had prior crizotinib therapy.
  7. Patients may be included if they are asymptomatic from their brain metastases (RTOG/EORTC grade 0) or if they have mild symptoms from their brain metastases not to exceed RTOG/ EORTC grade 1 or 2 (Grade 1: Fully functional status (i.e. able to work) with minor neurological findings, no medication needed; Grade 2: Neurological findings present sufficient to require home care / nursing assistance may be required / medications including steroids/anti-seizure agents may be required) (Cox, James D., et al "Toxicity criteria of the radiation therapy oncology group (RTOG) and the European organization for research and treatment of cancer (EORTC)." International Journal of Radiation Oncology• Biology• Physics 31.5 (1995): 1341-1346).
  8. Neurologically symptomatic patients must not require immediate surgical or radiation therapy for their symptoms, as decided by an investigator.
  9. Have an Eastern Cooperative Oncology Group (ECOG) performance status ≤2.
  10. Have adequate organ function, as determined by

    • ALT/AST ≤2.5 × upper limit of normal (ULN); ≤5 × ULN is acceptable if liver metastases are present
    • Total serum bilirubin ≤1.5 × ULN (<3.0×ULN for patients with Gilbert syndrome)
