Bryostatin 1 in Treating Patients With Relapsed Non-Hodgkin's Lymphoma or Chronic Lymphocytic Leukemia

• Status: Completed
• Trial end date: 2001-11-01
• Target enrollment: 0
• Participant gender: All

Summary

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.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Barbara Ann Karmanos Cancer Institute
• Collaborator: National Cancer Institute (NCI)
• Treatments: Bryostatin 1; Vincristine
