  Purpose

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of cladribine when given with bryostatin 1 in treating patients with relapsed chronic lymphocytic leukemia.

Study Start Date: May 1998
Detailed Description:

OBJECTIVES:

  • Determine the maximum tolerated dose of cladribine when administered after bryostatin 1 in patients with relapsed chronic lymphocytic leukemia.
  • Determine the qualitative and quantitative toxic effects of this regimen in these patients.

OUTLINE: This is a multicenter, dose-escalation study of cladribine.

Patients receive bryostatin 1 IV continuously on days 1-3 immediately followed by cladribine IV continuously on days 4-8. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity. Patients who achieve complete remission (CR) receive 2 additional courses past CR.

Cohorts of 3-6 patients receive escalating dose levels of cladribine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.

Patients are followed at 3 weeks.

PROJECTED ACCRUAL: A minimum of 15 patients will be accrued for this study.
