Arsenic Trioxide and Imatinib Mesylate in Treating Patients With Accelerated Phase or Blastic Phase Chronic Myelogenous Leukemia or Philadelphia Chromosome-Positive Acute Lymphoblastic Leukemia
A Phase 1/2 study testing arsenic trioxide and imatinib mesylate in people with Leukemia, run by Memorial Sloan Kettering Cancer Center at 1 site in United States.
Trial summary
RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide, work in different ways to stop cancer cells from dividing so they stop growing or die. Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Read more about this study

About this study
Official title: A Phase I/II Study to Determine Safety and Efficacy of Arsenic Trioxide (Trisneox™) in Combination With Imatinib (STI571, Gleevec™) in Patients With Chronic Myelogenous Leukemia in Accelerated or Blastic Phase Disease or Ph+ Acute Lymphoblastic Leukemia
RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide, work in different ways to stop cancer cells from dividing so they stop growing or die. Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Combining arsenic trioxide with imatinib mesylate may kill more cancer cells.
PURPOSE: This phase I/II trial is studying the side effects and best dose of arsenic trioxide when given with imatinib mesylate and to see how well they work in treating patients with accelerated phase or blastic phase chronic myelogenous leukemia or Philadelphia chromosome-positive acute lymphoblastic leukemia.
Read the detailed description
OBJECTIVES:
Primary
- Determine the maximum tolererated dose of arsenic trioxide when administered with imatinib mesylate in patients with accelerated or blastic phase chronic myelogenous leukemia or Philadelphia chromosome-positive acute lymphoblastic leukemia.
- Determine the rate of complete morphologic remission in the bone marrow of patients treated with this regimen.
OUTLINE: This is a phase I dose-escalation study of arsenic trioxide followed by a phase II study.
- Phase I:
- Induction therapy: Patients receive oral imatinib mesylate once daily on days 1-35 (weeks 1-5) and arsenic trioxide IV over 1-4 hours on days 1-5, 8-12, 15-19, and 22-26 (weeks 1-4).
Patients undergo bone marrow evaluation on week 5. Patients achieving a morphologic remission proceed to consolidation therapy. Patients not achieving morphologic remission receive a second course of imatinib mesylate as above on weeks 6-10 and arsenic trioxide as above on weeks 6-9. Patients are re-evaluated on week 10. Patients achieving morphologic remission proceed to consolidation therapy. Patients not achieving a morphologic remission are removed from study.
- Consolidation therapy: Patients receive oral imatinib mesylate as in induction therapy on approximately weeks 6-11 (or weeks 11-16*) and arsenic trioxide IV over 1-4 hours on days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, and 26 (approximately weeks 6-9 OR weeks 11-14*).
Patients who remain in morphologic remission receive a second course of imatinib mesylate as in induction therapy on approximately weeks 12-17 (or weeks 17-22*) and arsenic trioxide as above (in consolidation therapy) on approximately weeks 12-15 (or weeks 17-20*).
NOTE: *For patients who receive a second course of induction therapy
Cohorts of 6 patients receive escalating doses of arsenic trioxide until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.
- Phase II: Patients receive arsenic trioxide at the MTD and imatinib mesylate as in phase I.
Treatment in both phases continues in the absence of unacceptable toxicity or disease progression.
After completion of consolidation therapy, patients may continue imatinib mesylate off study at the discretion of the physician. Patients who become candidates for stem cell transplantation at any time during the study are removed from study.
PROJECTED ACCRUAL: A total of 6-43 patients (6-12 for phase I and 37 [including 6 patients from phase I] for phase II) will be accrued for this study within 2 years.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing arsenic trioxide and imatinib mesylate in people with Leukemia, run by Memorial Sloan Kettering Cancer Center at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. 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 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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.
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 Jun 2013; AzTrials last refreshed its copy on 7 Nov 2026.
