About this study

Official title: A Phase 1 Study of Crizotinib in Combination With Conventional Chemotherapy for Relapsed or Refractory Solid Tumors or Anaplastic Large Cell Lymphoma

This phase I trial studies the side effects and the best dose of crizotinib when given together with combination chemotherapy in treating younger patients with solid tumors or anaplastic large cell lymphoma that has returned or does not respond to treatment. Crizotinib may stop the growth of tumor or cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cyclophosphamide, topotecan hydrochloride, dexrazoxane hydrochloride, doxorubicin hydrochloride, and vincristine sulfate, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving crizotinib together with combination chemotherapy may be a better treatment for patients with solid tumors or anaplastic large cell lymphoma.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To estimate the recommended phase 2 dose (RP2D) or maximum tolerated dose (MTD) of crizotinib administered orally twice daily in combination with topotecan (topotecan hydrochloride) and cyclophosphamide in children with refractory/relapsed solid tumors or anaplastic large cell lymphoma (ALCL).

II. To define and describe the toxicities of crizotinib in combination with topotecan and cyclophosphamide administered on this schedule.

III. To estimate the recommended phase 2 dose (RP2D) or maximum tolerated dose (MTD) of crizotinib administered orally twice daily in combination with vincristine (vincristine sulfate) and doxorubicin (doxorubicin hydrochloride)/dexrazoxane (dexrazoxane hydrochloride) in children with refractory/relapsed solid tumors or ALCL.

IV. To define and describe the toxicities of crizotinib in combination with vincristine and doxorubicin/dexrazoxane administered on this schedule.

  1. To characterize the pharmacokinetics of crizotinib in children with relapsed/refractory cancer when combined with either topotecan and cyclophosphamide or vincristine and doxorubicin/dexrazoxane.

SECONDARY OBJECTIVES:

  1. To preliminarily define the antitumor activity of crizotinib in combination with either topotecan and cyclophosphamide or vincristine and doxorubicin/dexrazoxane within the confines of a Phase 1 study.

II. To preliminarily examine the relationship between anaplastic lymphoma kinase (ALK) status in patients with neuroblastoma or ALCL and response to crizotinib in combination with either topotecan and cyclophosphamide or vincristine and doxorubicin/dexrazoxane.

III. To preliminarily examine the relationship between minimal residual disease (MRD) status and clinical response to crizotinib in combination with either topotecan and cyclophosphamide or vincristine and doxorubicin/dexrazoxane in patients with ALCL.

IV. To use a questionnaire to gather preliminary information on the palatability of the oral solution formulation of crizotinib.

  1. To examine ALK and MET proto-oncogene (c-Met) expression, copy number and mutations status in archival tumor tissue from solid tumor and ALCL patients.

VI. To use a questionnaire to gather information on the acceptability of the crizotinib capsule formulation.

OUTLINE: This is a dose-escalation study of crizotinib. Patients are assigned to Part A or Part B based on the treating physician's choice and availability of a reservation. After closure of Part A and Part B, patients are assigned to Part C.

PART A (CLOSED TO ACCRUAL 10/3/14): Patients receive crizotinib (oral solution) orally (PO) twice daily (BID) on days 1-21, cyclophosphamide intravenously (IV) once daily (QD) on days 1-5, and topotecan hydrochloride IV QD on days 1-5. Treatment repeats every 21 days for up to 35 courses in the absence of disease progression or unacceptable toxicity.

PART B (CLOSED TO ACCRUAL 10/3/14): Patients receive crizotinib (oral solution) PO BID as in Part A. Patients also receive vincristine sulfate IV on day 1, dexrazoxane hydrochloride IV on day 1, and doxorubicin hydrochloride IV over 15 minutes on day 1. Treatment repeats every 21 days for up to 35 courses in the absence of disease progression or unacceptable toxicity.

PART C: Patients receive crizotinib (capsule formulation) PO BID, cyclophosphamide IV QD, and topotecan hydrochloride IV QD as in Part A. Treatment repeats every 21 days for up to 35 courses in the absence of disease progression or unacceptable toxicity.

PART D: Patients receive crizotinib (microsphere formulation) PO BID, cyclophosphamide IV QD, and topotecan hydrochloride IV QD as in Part A. Treatment repeats every 21 days for up to 35 courses in the absence of disease progression or unacceptable toxicity.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Crizotinib, Cyclophosphamide and Dexrazoxane Hydrochloride in people with Childhood Solid Neoplasm and Recurrent Childhood Anaplastic Large Cell Lymphoma, run by Children's Oncology Group at 23 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 40 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 23 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

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 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.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Jan 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum Tolerated Dose (MTD) of Crizotinib (time frame: Up to 21 days). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01606878, which also lists 2 linked publications.

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 Jan 2024.
