Study Overview
Brief Summary
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.
PURPOSE: This phase I trial is studying the side effects and best dose of 12-O-tetradecanoylphorbol-13-acetate in treating patients with hematologic cancer or bone marrow disorder that has not responded to previous treatment.
Detailed Description
OBJECTIVES:
- Determine the maximum tolerated dose and dose limiting toxicity of 12-O-tetradecanoylphorbol-13-acetate (TPA) in patients with relapsed or refractory hematologic malignancies or bone marrow disorders.
- Determine the pharmacokinetics of TPA in these patients.
- Determine the effects of TPA on the cellular composition of blood and bone marrow in these patients.
OUTLINE: This is a dose-escalation study.
Patients receive 12-O-tetradecanoylphorbol-13-acetate (TPA) IV over 1 hour on days 1 and 8 followed by 2 weeks of rest. Courses repeat in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of TPA until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 1 of 6 patients experiences dose limiting toxicity.
