Intervention Details:

    Drug: imatinib mesylate

    Patients will receive treatment with imatinib mesylate at a dose of 600 mg by mouth once a day for 12 months. The study dose can be split but the dose of 600 mg must be given within a 12 hour period.
    Other Name: Gleevec

    Genetic: gene expression analysis

    Multidrug resistance genes: These studies will include: MDR1, MRP1, LRP, and BCRP. Bone marrow blocks or cut slides will be sent to Duke on the diagnostic AML samples. DNA will be eluted from the samples so that the above genes can be analyzed. Required samples include: 10 slides of cytospins from the initial newly diagnosed sample for immunohistochemistry. Additionally, paraffin blocks (3 thick sections and 2 thin sections) are needed. These assays will be performed by Dr. Francis Ali-Osman and Dr. Arati Rao at Duke University Medical Center.

    Samples will be sent to the following address:

    Dr. David Rizzieri 2400 Pratt Street Duke North Pavilion, Suite 100 Duke University Medical Center Durham, NC 27710 Phone number: (919) 668-1040

    Other Name: MRD

    Genetic: mutation analysis

    FLT3 mutation analysis (on bone marrow aspirate or peripheral blood): These analyses will be performed by pathology at the time of diagnosis, at the participating institution. Samples will be analyzed for the FLT3 ITD and/or D835 mutation by PCR.
    Other Name: FLT3

    Genetic: polymerase chain reaction

    4.4 AF1q gene analysis (on bone marrow aspirate): Diagnostic frozen samples will be analyzed in the lab of Dr. William Tse, if the participating site has these samples available from an existing tissue repository. Samples will be frozen in liquid nitrogen and shipped to Dr. Tse’s lab in dry ice. Once samples arrive at Dr. Tse’s lab, they will be stored in liquid nitrogen until analysis. Samples will be thawed and examined for viability using trypan blue staining. The pure blast population will be sorted out (500,000 to 1 million cells are needed). Total RNA will be isolated from marrow mononuclear cells using standard TriZol method and quantitative real-time PCR will be performed as according to (17).

    The address for Dr. Tse’s lab is:

    William Tse, M.D. 2nd Floor, PO Box 9162 Hematology/Oncology West Virginia University Mary Babb Randolph Cancer Center Morgantown, West Virginia 26506 Phone: 304-293-4980

    Other Name: AF1Q gene analysis

    Other: flow cytometry

    4.1 C-kit MFI on AML samples will be calculated by using a CD45/ orthogonal light scatter gate to isolate blasts. The MFI will be calculated as the c-kit mean channel number (MCN) of the blasts/ MCN auto fluorescence (See Examples, Figures 1 and 2 in Appendix 2). These calculations will be done centrally at the Cleveland Clinic by Dr. Eric Hsi in pathology. In cases where flow cytometry is done at the participating institution, these samples will be collected and analyzed per their local procedures. Flow cytometry and flow scatter gram results will be sent to Cleveland Clinic for review before the patient begins treatment.
    Other Name: C-kit MFI, CD117

    Procedure: biopsy

    Diagnostic bone marrow biopsy/aspirate must be done within 3 weeks of registration documenting complete remission
    Other Name: bone marrow biopsy/aspirate

Detailed Description:



  • To determine whether adding imatinib mesylate as maintenance therapy improves progression-free survival in patients with c-kit positive acute myeloid leukemia (AML) compared with historical controls.


  • To assess the feasibility of administering imatinib mesylate as maintenance therapy after the completion of induction and consolidation therapy in these patients.
  • To evaluate potential mechanisms of relapse/resistance in c-kit positive AML by examining multidrug resistance gene expression and AF1q gene expression and to determine whether these levels correlate with c-kit expression.

OUTLINE: This is a multicenter study.

Patients receive oral imatinib mesylate once daily for up to 12 months.

Bone marrow and peripheral blood are collected at baseline. Laboratory endpoints are evaluated by flow cytometry; mutation and gene analysis by PCR.
