Arsenic Trioxide and Imatinib Mesylate in Treating Patients With Chronic Myelogenous Leukemia

2014-08-27 03:55:33 | BioPortfolio

Summary

RATIONALE: Drugs used in chemotherapy use 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 cancer cell growth. Combining chemotherapy with imatinib mesylate may kill more cancer cells.

PURPOSE: Phase I/II trial to study the effectiveness of combining arsenic trioxide with imatinib mesylate in treating patients who have chronic phase chronic myelogenous leukemia.

Description

OBJECTIVES:

- Determine the safety and tolerability of arsenic trioxide and imatinib mesylate in patients with resistant chronic phase chronic myelogenous leukemia.

- Determine potential dose-limiting toxic effects in patients treated with this regimen.

- Determine the pharmacokinetics of this regimen in these patients.

OUTLINE: This is a multicenter study.

Patients receive oral imatinib mesylate once daily and arsenic trioxide IV over 1-2 hours on days 1-5 of week 1 and then twice weekly. Treatment continues for 1 year in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 18-24 patients (at least 6 patients for phase I and at least 12 patients for phase II) will be accrued for this study .

Medical and Biotech [MESH] Definitions

A tyrosine kinase inhibitor and ANTINEOPLASTIC AGENT that inhibits the BCR-ABL kinase created by chromosome rearrangements in CHRONIC MYELOID LEUKEMIA and ACUTE LYMPHOBLASTIC LEUKEMIA, as well as PDG-derived tyrosine kinases that are overexpressed in gastrointestinal stromal tumors.

A pyrimidine and thiazole derived ANTINEOPLASTIC AGENT and PROTEIN KINASE INHIBITOR of BCR-ABL KINASE. It is used in the treatment of patients with CHRONIC MYELOID LEUKEMIA who are resistant or intolerant to IMATINIB.

A shiny gray element with atomic symbol As, atomic number 33, and atomic weight 75. It occurs throughout the universe, mostly in the form of metallic arsenides. Most forms are toxic. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), arsenic and certain arsenic compounds have been listed as known carcinogens. (From Merck Index, 11th ed)
