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: Phase I/II trial to study the effectiveness of bryostatin 1 in treating patients who have relapsed non-Hodgkin's lymphoma or chronic lymphocytic leukemia.

Condition Treatment or Intervention Phase
recurrent diffuse small lymphocytic/marginal zone lymphoma
recurrent adult diffuse small cleaved cell lymphoma
recurrent adult lymphoblastic lymphoma
recurrent grade III follicular large cell lymphoma
recurrent adult immunoblastic large cell lymphoma
recurrent adult diffuse small noncleaved cell/Burkitt's lymphoma
recurrent adult diffuse mixed cell lymphoma
recurrent mantle cell lymphoma
refractory chronic lymphocytic leukemia

Official Title: Phase II Study of Bryostatin 1 in Relapsed non-Hodgkin's Lymphoma and Chronic Lymphocytic Leukemia with Addition of Vincristine for Disease Progression

Further Study Details: 

Study start: December 1996

OBJECTIVES: I. Assess the efficacy of bryostatin 1 administered as a 72-hour infusion in patients with relapsed non-Hodgkin's lymphoma and chronic lymphocytic leukemia.

II. Gain information regarding the toxicity and tolerability of escalated vincristine doses given after each bryostatin 1 infusion in cohorts of patients who fail to respond to bryostatin alone.

III. Determine the qualitative and quantitative toxic effects of bryostatin 1 in these patients.

IV. Determine the duration of response and survival following treatment with bryostatin 1.

PROTOCOL OUTLINE: All patients receive bryostatin 1 by 72-hour continuous infusion every 2 weeks until disease progression or until 2 courses beyond documentation of complete remission. Response is assessed after every 4 courses.

Patients with disease progression who continue to meet the eligibility criteria receive vincristine within 2 hours after completion of each bryostatin 1 infusion. Groups of 3-6 patients receive escalated doses of vincristine until the maximum tolerated dose with bryostatin 1 is determined. Courses repeat every 2 weeks, as above; no individual dose escalation is allowed.

No concurrent steroids are permitted.

Patients are followed for survival.

PROJECTED ACCRUAL: A total of 25 evaluable patients with low-grade NHL or CLL will be entered over approximately 20 months if there are 2-4 responses in the first 15 patients. A total of 20 evaluable patients with intermediate- or high-grade NHL will be entered over approximately 2 years if there are 1 or 2 responses in the first 10 patients.


Ages Eligible for Study:  18 Years and above
