Chemotherapy Plus Sargramostim in Treating Patients With Refractory Myeloid Cancer
Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Colony-stimulating factors such as sargramostim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. Phase I trial to study the effectiveness of bryostatin 1 combined with sargramostim in treating patients who have refractory myeloid cancer

|Official Title:||Dose Finding Study of Bryostatin-1 and GM-CSF in Refractory Myeloid Malignancies|
- MTD defined as the dose at which the CRM estimates that 30% of patients will experience dose-limiting toxicity (DLT) assessed using CTC version 2.0 [ Time Frame: 56 days ] [ Designated as safety issue: Yes ]
|Study Start Date:||March 2001|
|Primary Completion Date:||January 2010 (Final data collection date for primary outcome measure)|
Experimental: Treatment (bryostatin 1 and sargramostim)
Patients receive bryostatin 1 IV continuously and GM-CSF subcutaneously once daily on days 1-21. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity. Patients with disease stabilization or improvement may continue treatment for up to 12 courses.

I. To determine the maximally tolerated dose of continuous intravenous infusion bryostatin-1 when given in combination with GM-CSF.
II. To describe and quantify the frequency of toxicity of the combination of continuous intravenous infusion bryostatin-1 and subcutaneously administered GM-CSF.
I. To describe the impact of the combination of bryostatin-1 and GM-CSF on the differentiation and cell cycle distribution of myeloid cells in vivo.
II. To describe the impact of the combination of bryostatin-1 and GM-CSF on T lymphocyte populations.
III. To assess the pharmacokinetics of continuous infusion bryostatin-1.
OUTLINE: This is a dose-escalation study of bryostatin 1.
Patients receive bryostatin 1 IV continuously and sargramostim (GM-CSF) subcutaneously once daily on days 1-21. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity. Patients with disease stabilization or improvement may continue treatment for up to 12 courses.
Cohorts of 2 patients receive escalating doses of bryostatin 1 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 30% of patients experience dose-limiting toxicity.
PROJECTED ACCRUAL: A maximum of 45 patients will be accrued for this study within 12-18 months.
