Brief Summary

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.

Detailed Description

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.

Conditions

Anaplastic Large Cell Lymphoma, ALK-Positive; Inflammatory Myofibroblastic Tumor; Other Solid Tumor

Study Design

• Allocation Method: NON_RANDOMIZED
• Intervention Model: SEQUENTIAL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Phase 1

Phase 1:

• To estimate the MTD/RP2D regimen of brigatinib monotherapy when administered in pediatric and AYA patients with ALK+ ALCL or ALK+ solid tumors.
• To characterize the PK of brigatinib administered as monotherapy in pediatric and AYA patients with ALK+ ALCL or ALK+ solid tumors.

Note that:

• If the MTD is not reached at the highest proposed test dose, no further dose-escalation will be performed.
• Pediatric PK data, compared to exposure in adults, and cumulative toxicity, will be taken into consideration to determine the RP2D regimen.

Eligibility Criteria

Inclusion Criteria

1. 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.

2. 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.

3. Patients are required to provide prior results showing an activating ALK aberration in the tumor per local laboratory results, and material needs to be available for central laboratory confirmation of ALK status. For ALK+ ALCL, detection of ALK with immunohistochemistry (IHC) is sufficient for inclusion, all others require molecular evidence of a ALK fusion gene or mutation by FISH, PCR or NGS. ALK detection will be confirmed centrally with FISH.

4. For Phase 1:

• Patients with ALCL must be relapsed/refractory or intolerant to standard therapies. Refractory disease for ALCL is defined as:

o no response to ALCL99/other standard of care chemotherapy (SD or PD of measurable lesions), and/or

o MRD-positivity by qualitative PCR for NPM-ALK prophase after one block ALCL99/other standard of care chemotherapy (before the second course of chemotherapy).

• Patients with relapsed/refractory (R/R) IMT must not be suitable for curative surgical resection without causing mutilation. Newly diagnosed patients with unresectable ALK+ IMT, or when surgery would imply severe mutilation may also be included, as well as metastatic disease.
• Patients with other solid tumors (excluding IMT) must have relapsed or refractory disease.

5. For Phase 2, patients must have measurable and/or evaluable disease:

• Patients with ALCL must be relapsed/refractory. Refractory disease for ALCL is defined as:

• no response to ALCL99/other standard of care chemotherapy (SD or PD of measurable lesions), and/or
• MRD-positivity by qualitative PCR for NPM-ALK prophase after one block ALCL99/other standard of care chemotherapy (before the second course of chemotherapy).
• Patients with R/R IMT Relapsed/refractory ALK+ IMT, or newly diagnosed, including advanced and metastatic, ALK+ IMT which cannot be surgically resected without causing mutilation

6. Performance Status: Karnofsky performance status ≥40% for patients >16 years of age or Lansky Play Scale ≥40% for patients ≤16 years of age.

7. Patients must not be receiving other investigational medications (defined as medicinal products not yet approved for any indications, including alternative/herbal therapies) within 30 days of first dose of study drug or while on study.

8. For patients receiving prior therapy:

• Patients 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.
• Patients 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.
• Patients who have experienced relapse after a prior 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.

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.

o 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).
