RATIONALE: Drugs used in chemotherapy, such as fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Darbepoetin alfa may cause the body to make more red blood cells. It is not yet known whether fludarabine is more effective with or without darbepoetin alfa in treating chronic lymphocytic leukemia.

PURPOSE: This phase III trial is studying fludarabine to see how well it works when given together with or without darbepoetin alfa in treating older patients with chronic lymphocytic leukemia.

Condition Intervention Phase
Biological: darbepoetin alfa
Drug: fludarabine phosphate
Phase 3

Study Type: Interventional
Study Design: Masking: Open Label
Primary Purpose: Treatment

  • Anemia [ Designated as safety issue: No ]
  • Transfusion requirements [ Designated as safety issue: No ]
  • Quality of life [ Designated as safety issue: No ]
  • Duration and frequency of hospitalization [ Designated as safety issue: No ]
  • Event-free survival [ Designated as safety issue: No ]
  • Progression-free survival [ Designated as safety issue: No ]
  • Overall survival [ Designated as safety issue: No ]
  • Medical-economical impact [ Designated as safety issue: No ]

Estimated Enrollment: 348
Study Start Date: September 2004
Detailed Description:


  • Compare the efficacy of fludarabine with or without darbepoetin alfa in geriatric patients with chronic lymphocytic leukemia and relevant comorbidities.
  • Determine the effect of these regimens in reducing anemia, lowering the requirements of transfusion, and reducing the duration and frequency of hospitalization in these patients.
  • Determine the quality of life of patients treated with these regimens.
  • Determine event-free, progression-free, and overall survival of patients treated with these regimens.
  • Evaluate the medical-economical aspects of these regimens in these patients

OUTLINE: This is a multicenter study. Patients are stratified according to hemoglobin value (< 12 g/dL [stratum 1] vs > 12 g/dL [stratum 2]). Patients are assigned to 1 of 2 treatment strata.

  • Stratum 1: Patients receive fludarabine IV on days 1, 3, and 5. Treatment repeats every 28 days for up to 6 courses. Patients also receive darbepoetin alfa subcutaneously once weekly for up to 6 weeks.
  • Stratum 2: Patients receive fludarabine as in stratum 1. Quality of life is evaluated periodically.

PROJECTED ACCRUAL: A total of 348 patients will be accrued for this study.
