Brief summary

This phase I trial is studying the side effects and best dose of bryostatin-1 when given together with vincristine in treating patients with chronic lymphocytic leukemia, non-Hodgkin's lymphoma, or multiple myeloma. 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

Detailed description

PRIMARY OBJECTIVES: I. To determine the maximum tolerated dose of bryostatin 1 as a 24 hour infusion and vincristine when administered sequentially. II. To determine the effect of this combination on programmed cell death (apoptosis). III. To determine the immunomodulatory effect of bryostatin 1. IV. To observe patients for clinical antitumor response after giving combination bryostatin 1 and vincristine. OUTLINE: This is a dose-escalation study of bryostatin 1. Patients receive bryostatin 1 IV over 24 hours followed immediately by vincristine IV. Treatment repeats every 2 weeks in the absence of disease progression or unacceptable toxicity. Patients completing 6 courses of therapy may receive subsequent courses every 3 weeks and then every 4 weeks after 24 months of treatment. Patients may return to a 2- or 3-week treatment course at the discretion of the principal investigator. Cohorts of 3 patients receive escalating doses of bryostatin 1 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 1 of 3 patients experience dose-limiting toxicity. Patients are followed every 3 months.
