Brief Summary:

RATIONALE: Drugs used in chemotherapy, such as fludarabine, mitoxantrone, and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. Colony stimulating factors, such as G-CSF, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of combination chemotherapy. It is not yet known whether giving combination chemotherapy alone is more effective than combination chemotherapy together with G-CSF in treating patients with chronic lymphocytic leukemia.

PURPOSE: This randomized phase III trial is studying giving combination chemotherapy together with G-CSF to see how well it works compared to giving combination chemotherapy alone in treating patients with relapsed stage I, stage II, stage III, or stage IV chronic lymphocytic leukemia.


Condition or disease Intervention/treatment Phase
Chronic Lymphocytic Leukemia Biological: Filgrastim Drug: Fludarabine Drug: Cyclophosphamide Drug: Mitoxantrone Phase 3

Detailed Description:

OBJECTIVES:

Primary

  • Compare the rate of remission, severe infections, and side effects in patients with relapsed advanced chronic lymphocytic leukemia treated with fludarabine, mitoxantrone hydrochloride, and cyclophosphamide with vs without filgrastim.

Secondary

  • Compare the overall survival, progression-free survival, and quality of remission in these patients.

OUTLINE: This is a multicenter, randomized study. Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive fludarabine IV on days 1-3, mitoxantrone hydrochloride IV on day 1, and cyclophosphamide IV on days 1-3.
  • Arm II: Patients receive fludarabine, mitoxantrone hydrochloride, and cyclophosphamide as in arm I and filgrastim (G-CSF) beginning on day 6 and continuing until blood counts recover.

In both arms, treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 165 patients will be accrued for this study.
