Primary Outcome Measures:
  • This study is designed to test the therapeutic effect of combining Bryostatin 1 with the known maximum tolerated dose of all-trans retinoic acid in patients with either MDS or AML.

Secondary Outcome Measures:
  • This study will also determine the ability of Bryostatin 1 in combination with ATRA in humans to induce differentiation of human leukemic cells and to cause changes in the levels of protein kinase C isoenzymes in these cells.

Estimated Enrollment: 40
Study Start Date: May 1997
Study Completion Date: August 2000
Primary Completion Date: August 2000 (Final data collection date for primary outcome measure)
Detailed Description:

All patients receive all-trans retinoic acid at a dose of 150 mg/m2/day and patients are randomized to one of two schedules of Bryostatin 1.

Arm 1: Bryostatin 1 is administered at a dose of 60 mcg/m2 as a 30 minute intravenous (IV) infusion on days 8 and 22.

Arm 2: Bryostatin 1 is administered at a dose of 40 mcg/m2 as a 72 hour IV infusion starting on days 8 and 22.

Patients are assessed for response on day +50 with a bone marrow examination and patients with either a clinical response or stable disease receive further therapy.

Bryostatin 1 pharmacokinetic samples are to be drawn on days 1, 8 and 50 of each cycle.
