Alternate Title

Chemotherapy and Biological Therapy With or Without Bone Marrow or Peripheral Stem Cell Transplant in Treating Patients With Chronic Myelogenous Leukemia

Basic Trial Information

Objectives

1. Compare survival in patients with chronic myelogenous leukemia in early chronic phase treated with allogeneic bone marrow transplantation vs drug treatment with or without autologous peripheral blood stem cell transplantation.
2. Compare survival of patients with late-phase disease treated with high-dose cytarabine vs low-dose cytarabine followed by autografting and interferon alfa maintenance.
3. Compare survival of patients not responding cytogenetically to treatment with continued interferon alfa vs hydroxyurea.
4. Determine frequency, time-point, and duration of hematological and cytogenetic remissions and of Philadelphia chromosome-negative and/or BCR-ABL-positive cells on the various treatments.
5. Correlate the quality of hematological and cytogenetic remissions with survival time in patients treated with these regimens.
6. Compare the course of the terminal phase in patients treated with these regimens.
7. Compare the toxic effects of these regimens in these patients.
8. Determine the effect of prognostic criteria and normal or subnormal WBC on chronic phase duration and survival time in patients treated with these regimens.
9. Compare the effect of early vs late high-dose therapy plus autografting on feasibility, toxicity, and survival times in these patients.

Outline

This is a randomized, multicenter study. Patients are stratified according to eligibility for transplantation (yes vs no).

All patients undergo cytoreduction comprising hydroxyurea (HU) IV daily.

Patients who are ineligible for or refuse transplantation are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive interferon alfa (IFN) subcutaneously (SC) daily. After 2 weeks of IFN therapy, patients also receive low-dose cytarabine (ARA-C) SC once daily for 10-15 days each month. Patients who do not achieve cytogenetic remission within 12 months continue to receive HU.

• Arm II: Patients receive IFN SC daily. After 2 weeks of IFN therapy, patients also receive low-dose ARA-C SC daily for 10-15 days each month. Patients who do not achieve cytogenetic remission within 12 months continue to receive IFN therapy SC daily.

Patients who are eligible for transplantation with a related donor undergo allogeneic bone marrow transplantation. Patients may receive HU or IFN prior to transplantation. Patients may also receive oral high-dose busulfan daily for 4 days with or without cyclophosphamide or cyclophosphamide with total body irradiation.

Patients who are eligible for transplantation but do not have a related donor undergo peripheral blood stem cell (PBSC) harvest and are randomized to 1 of 2 treatment arms.

• Arm III: Patients receive IFN and low-dose ARA-C as in arm I. Patients who accelerate on treatment may undergo autologous PBSC transplantation.

• Arm IV: Patients receive idarubicin IV, ARA-C IV over 2 hours, and etoposide IV on days 1-3. Patients then undergo leukapheresis. Beginning on day 8, patients receive filgrastim (G-CSF) SC daily until end of leukapheresis. Patients then receive oral high-dose busulfan daily for 4 consecutive days. The following day, patients undergo reinfusion of autologous PBSC. After blood count recovery, patients receive maintenance IFN 3 times weekly for 8 weeks and then daily.

Patients are followed every 3 months for 3 years and then every 6 months thereafter.
