Conditions: Leukemia
Keywords: relapsed refractory acute myeloid AML CML blast crisis
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 38
Healthy volunteers: no

Brief summary:
The purpose of the study is to find out what effects (good and bad) Gleevec® (Imatinib mesylate) combined with chemotherapy has on participants and their acute myeloid leukemia.

Detailed description:
In relapsed or resistant acute myeloid leukemia (a type of blood cancer where immature blood cells are increased, blocking normal blood cell production), different types of chemotherapy are used for treatment. Patients responded to all the chemotherapies in similar ways, but most of the responses did not last long if further stem cell transplantation was not done. Gleevec is believed to work by interfering with the abnormal protein by blocking it from telling the body to keep making more white blood cells that are abnormal.

The CLAG regimen is the standard chemotherapy used for relapsed AML (Acute Myeloid Leukemia). This study will add Gleevec® to the regimen for a period of 14 days. Gleevec® is approved by the Food and Drug Administration (FDA) for the treatment of chronic myeloid leukemia (CML) and some types of acute lymphoblastic leukemia (ALL). Its use in combination with CLAG regimen is considered experimental for the treatment of Acute Myeloid Leukemia/CML blast crisis.

Arms:
arm 1: Combined chemotherapy treatment (CLAG regimen) with Gleevec® (imatinib mesylate).

Interventions: intervention 1: CLAG Regimen intervention 2: Gleevec®
Intervention descriptions: intervention 1: The CLAG regimen consisted of: Cladribine, 5 mg/m\^2 administered via 2 hour IV daily for 5 consecutive days starting on day 2; Cytarabine, 2 mg/m\^2 administered through a 4 hour IV starting 2 hours after the ignition of Cladribine for 5 days starting on day 2; granulocyte colony-stimulating factor (G-CSF): 300 mcg subcutaneous (SC) for 6 days starting 12-24 hours (Day 1) before the first dose of Cladribine. intervention 2: Imatinib mesylate 400 mg orally twice daily was administered on day 2 to day 15. Re-induction was allowed if participant had partial response (PR).
