Spots Global Cancer Trial Database for Combination Chemotherapy Followed by Peripheral Stem Cell Transplantation in Treating Patients With Chronic Myelogenous Leukemia

Study Description

Brief Summary: RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Phase I/II trial to study the effectiveness of combination chemotherapy followed by peripheral stem cell transplantation in treating patients with chronic myelogenous leukemia.

Detailed Description: OBJECTIVES: I. Determine whether intensive idarubicin and cytarabine leads to adequate harvest of Philadelphia chromosome-negative peripheral blood stem cells (PBSC) in patients with chronic myelogenous leukemia in chronic phase. II. Determine the toxicity of this intensive regimen in these patients. III. Determine the graft-versus-leukemia effect induced in these patients by cyclosporine and interferon gamma post-PBSC transplantation. IV. Determine the transformation-free and overall survival in patients treated with a high-dose conditioning regimen comprising busulfan and cyclophosphamide followed by PBSC transplantation plus immunotherapy. OUTLINE: Patients receive idarubicin IV and cytarabine IV over 2 hours on days 1-3. When blood counts recover, Philadelphia chromosome negative peripheral blood stem cells (PBSC) are harvested. Filgrastim (G-CSF) is administered subcutaneously (SC) beginning 24 hours after completion of cytarabine infusion and continuing until blood counts have recovered for 3 consecutive days after harvest of PBSC. Patients with more than 5% blasts in marrow or any peripheral blasts, interferon resistance, interferon intolerance with poor prognosis, and clonal evolution proceed to conditioning followed by PBSC transplantation. Patients receive conditioning comprising oral busulfan every 6 hrs on days -8 to -5 and cyclophosphamide IV over 2 hours on days -4 and -3. PBSC are reinfused on day 0. Patients receive graft versus leukemia induction comprising cyclosporine IV over 4 hours every 12 hours on days 0-28 and interferon gamma SC beginning on day 7 and continuing every other day through day 28. Patients are followed every 3 months for 1 year and then annually for 5 years. PROJECTED ACCRUAL: A total of 15-43 patients will be accrued for this study within 4-8 years.
