Who may be able to join
- Patients must be 1 and < 26 years of age at the time of enrollment, and able to swallow brigatinib tablets at the time of enrollment, with a minimum weight of 10 kg. Note: for phase 1 only patients ≤18 years old will be eligible, A liquid formulation for children with a weight lower than 10 kg or for those that cannot swallow tablets is in development.
- Patients must have a confirmed diagnosis of cancer histologically at baseline. In patients where a repeat biopsy at relapse (or moment of refractory disease) is considered not feasible by the treating physician, archived material from diagnosis needs to be available for central review.

About this study
Official title: A Phase I/II Study of Brigatinib in Pediatric and Young Adult Patients With ALK+ Anaplastic Large Cell Lymphoma, Inflammatory Myofibroblastic Tumors or Other Solid Tumors
This is an open-label, phase I-II dose-escalation and expansion study designed to define the recommended dose of brigatinib as monotherapy in pediatric and young adult patients with ALK+ ALCL, IMT or other solid tumors and to evaluate the pharmacokinetics (PK), (long-term) safety, and efficacy of brigatinib in these children.

This is an open-label, phase I-II dose-escalation and expansion study designed to define the recommended dose of brigatinib as monotherapy in pediatric and young adult patients with ALK+ ALCL, IMT or other solid tumors and to evaluate the pharmacokinetics (PK), (long-term) safety, and efficacy of brigatinib in these children.
Phase 1 part will be a dose escalation part using a rolling-6 design, aiming to accrue a minimum of 6 and a maximum of 18 evaluable patients in two dose-levels (and minus 1), at least 2/3 of included patients will be ≤18 years.
Phase 2 will be the tumor cohort expansion part of the study to further evaluate the safety, tolerability, and clinical activity/efficacy of brigatinib as monotherapy in two tumor-specific cohorts:
- Cohort B1: ALK+ IMT Planned sample size for Phase 2 is 12 patients with IMT. Patients who are included in the monotherapy Phase 1 IMT dose-escalation portion of the study will be included in the expansion cohort analysis if they receive the RP2D, and will count towards the total sample size of 12 patients.
- Cohort B2: ALK+ ALCL Planned sample size for Phase 2 is 22 patients with ALCL. Patients who are included in the monotherapy Phase 1 ALCL dose-escalation portion of the study will be included in the expansion cohort analysis if they receive the RP2D, and will count towards the total sample size of 22 patients.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Maaike Boonstra (+31642055985, m.boonstra@prinsesmaximacentrum.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Phase 1: assess the MTD/RP2D regimen (time frame: 2 years). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Dec 2025.
