Anaplastic Lymphoma Kinase Positive (ALK +) Anaplastic Large Cell Lymphoma, Inflammatory Myofibroblastic Tumors, Solid Tumors
About this trial
This is an interventional treatment trial for Anaplastic Lymphoma Kinase Positive (ALK +) Anaplastic Large Cell Lymphoma focused on measuring Drug Therapy
Eligibility Criteria
Inclusion Criteria:
- Participants must have confirmed cancer histologically or cytologically diagnosed at baseline
- Participants are required to provide prior results showing an activating ALK aberration in the tumor (bone marrow aspirate, peripheral blood samples, biopsy, etc) documented by fluorescence in situ hybridization (FISH), polymerase chain reaction (PCR) for the ALK-fusion transcript, next generation sequencing (NGS) or ALK immunohistochemistry (ALK immunohistochemistry can be used as a surrogate for FISH or NGS)
- Phase 1, participants must be relapsed/refractory or intolerant to standard therapies or without option of established systemic therapy
Phase 2, participants must have measurable and/or evaluable disease:
- Arm 1: IMT participants must not be suitable for curative surgical resection
- Arm 2: participants must have relapsed/refractory ALCL
- Performance Status: Karnofsky performance status ≥40% for participants >16 years of age or Lansky Play Scale ≥40% for participants ≤16 years of age
For participants receiving prior therapy:
- Participants must have recovered to Grade <2 NCI CTCAE v5.0 or to baseline, from any nonhematologic toxicities (except alopecia and peripheral neuropathy) due to previous therapy
- Participants who relapsed while receiving cytotoxic therapy: At least 14 days must have passed since the completion of the last dose of chemotherapy before the first dose of brigatinib can be given
- Participants with hematologic malignancy and prior hematopoietic stem cell transplant (HSCT): Participants who have experienced relapse after a HSCT are eligible, provided they have no evidence of acute or chronic graft-versus-host disease (GVHD), are not receiving GVHD prophylaxis or treatment, and are at least 45 days posttransplant at the time of enrollment
- Hematopoietic growth factors: Before the first dose of brigatinib, at least 7 days must have passed since completion of therapy with granulocyte colony-stimulating factor or other growth factors, and at least 14 days must have passed since completion of therapy with pegfilgrastim
Biologics and Targeted Therapies:
- Immunotherapy: Before the first dose of brigatinib, at least 30 days must have passed after the completion of any type of immunotherapy, (eg, monoclonal antibodies [anti-PD1/PDL1], tumor vaccines, chimeric antigen receptor [CAR] T cells, etc.)
- Other: before the first dose of brigatinib, at least 7 days must have passed since the last dose of a biologic agent. For agents that have known adverse events (AEs) occurring beyond 7 days after administration, this period must be extended beyond the time during which AEs are known to occur. The duration of this interval must be discussed with the sponsor's medical monitor/designee
- Immunosuppressive therapy: Before the first dose of brigatinib, at least 14 days must have passed after the completion of immunosuppressive therapy (including regimens following stem cell transplant)
- For symptomatic participants that urgently need relief (eg, airway obstruction), therapeutic doses of corticosteroids may be administered for a short course (up to 5 days)
- Radiotherapy (XRT): No washout period is necessary for radiation given to any extramedullary site other than the CNS and lungs; ≥6 weeks must have passed if participants received prior total body irradiation or craniospinal or cranial XRT; ≥28 days must have passed if participants received radiotherapy to the lung(s)
- Normal QT interval corrected per Fridericia method (QTcF) on screening electrocardiogram (ECG), defined as QTcF of ≤450 ms
- Have life expectancy of ≥3 months.
Exclusion Criteria:
- Participants receiving systemic treatment with strong or moderate cytochrome P450 3A (CYP3A) inhibitors or inducers within 14 days prior to the first dose of study drug
- Previous treatment with brigatinib or other ALK inhibitors (except for participants in Phase 1)
- Participants with completely resected stage-1 (ALCL and other lymphomas) disease
- Participants with disease limited to skin (ALCL and other lymphomas)
- Diagnosis of another concurrent primary malignancy
Clinically significant cardiovascular disease, including any of the following:
- Myocardial infarction or unstable angina within 6 months of study entry
- Uncontrolled hypertension defined as persistent elevation of systolic and/or diastolic blood pressures to ≥95th percentile based on age, sex, and height percentiles despite appropriate antihypertensive management
- Planned non-protocol chemotherapy, radiation therapy, another investigational agent, or immunotherapy while participant is on study treatment
- Uncontrolled seizure disorder. (Participants with seizure disorders that do not require antiepileptic drugs, or are well controlled with stable doses of antiepileptic drugs are eligible).
- Any illness that affects gastrointestinal absorption
- Ongoing or active systemic infection, active seropositive HIV, or known active hepatitis B or C infection.

Phase 1: Brigatinib
Ph 2:Brigatinib (Unresectable/Recurrent ALK+ IMT) Participants
Ph 2 :Brigatinib (Relapsed/Refractory ALK+ ALCL) Participants
Brigatinib tablet or age-appropriate formulation (AAF), orally once daily in 28-day Cycles with reference to adult dose of 90 mg in Week 1 and 180 mg starting in Week 2 based on participant's weight as dose level 1. Participants could receive dose level 2 based on safety and tolerability of dose level 1 in dose escalation phase (Ph).
Brigatinib recommended phase 2 dose (RP2D) determined during phase 1, tablet or AAF orally QD in participants with Unresectable/ Recurrent ALK+ IMT for up to 2 years in dose expansion phase.
Brigatinib RP2D determined during phase 1, tablet or AAF orally QD in participants with Relapsed/ Refractory ALK+ ALCL for up to 2 years in dose expansion phase.
