Combination Chemotherapy in Treating Patients With Relapsed or Refractory Acute Lymphocytic Leukemia
Recruitment status was Active, not recruiting
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells.
PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have relapsed or refractory acute lymphocytic leukemia.
Drug: daunorubicin hydrochloride
Drug: leucovorin calcium
|Study Design:||Primary Purpose: Treatment|
|Official Title:||TREATMENT OF ADULT PATIENTS WITH RELAPSING ACUTE LYMPHOCYTIC LEUKEMIA, A MULTICENTER TRIAL|
|Study Start Date:||January 1993|
OBJECTIVES: I. Determine the toxic effects and feasibility of high-dose cytarabine and idarubicin in patients with refractory or relapsed acute lymphocytic leukemia (ALL) after a complete remission (CR) of less than 18 months. II. Determine the response of patients with ALL in first relapse after a CR of 18 months or more treated with a 2-phase re-induction regimen comprising prednisolone, vindesine, daunorubicin, asparaginase, intrathecal (IT) cytarabine, IT dexamethasone, and IT methotrexate followed by prednisolone, ifosfamide, high-dose methotrexate, leucovorin calcium, etoposide, and cytarabine (with a dose-escalation study of etoposide and cytarabine). III. Compare the effectiveness of these 2 regimens administered to these patients with the regimen administered to historic controls (protocol GER-ALL-REZ- 01/88).
OUTLINE: This is a dose-escalation, multicenter study. Patients are stratified by center, duration of complete remission (CR) (less than 18 months vs 18 months or more), and refractory disease (yes vs no). Patients with refractory or relapsed disease after a CR of less than 18 months are treated on Regimen A. Patients in first relapse after a CR of 18 months or more are treated on Regimen B. Regimen A: Patients receive idarubicin IV over 30 minutes followed by cytarabine IV over 3 hours on days 1-3 and filgrastim (G-CSF) subcutaneously (SC) daily beginning on day 5 and continuing until blood counts recover. Regimen B (2-phase reinduction): Patients receive oral prednisolone on days 1-21; vindesine IV and daunorubicin IV on days 1, 8, and 15; asparaginase IV on days 7, 8, 14, and 15; and methotrexate intrathecally (IT), cytarabine IT, and dexamethasone IT on days 1 and 8. When blood counts recover, patients receive oral prednisolone and ifosfamide IV over 1 hour on days 1-4; high-dose methotrexate IV continuously on day 1 followed by standard leucovorin calcium rescue; etoposide IV over 1 hour followed at least 8 hours later by cytarabine IV over 3 hours on days 3 and 4; and G-CSF SC beginning on day 6 and continuing until blood counts recover. Cohorts of 6 patients or more receive escalating doses of etoposide and cytarabine until the maximum tolerated dose is determined.
PROJECTED ACCRUAL: Approximately 60 patients (30 per regimen) will be accrued for this study within 2 years.
