Chemotherapy and Monoclonal Antibody Therapy in Treating Patients With Advanced Myeloid Cancer

Memorial Sloan Kettering Cancer Center32 enrolled

Overview

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining monoclonal antibody therapy with chemotherapy may kill more cancer cells. PURPOSE: Phase I/II trial to study the effectiveness of combining chemotherapy and monoclonal antibody therapy in treating patients who have advanced myeloid cancer.

OBJECTIVES: * Determine the maximum tolerated dose of bismuth Bi 213 monoclonal antibody M195 following cytarabine in patients with advanced myeloid malignancies. * Determine the antileukemic effects of this treatment in this patient population. * Determine the toxicity of this treatment in this patient population. * Determine the complete remission rate of patients treated with this treatment regimen. OUTLINE: This is a dose escalation study of bismuth Bi 213 monoclonal antibody M195 (Bi213 MOAB M195). Patients receive cytarabine IV continuously on days 1-5. Beginning between days 7 and 14, patients receive Bi213 MOAB M195 IV over 5 minutes up to 4 times daily over 1-4 days. Patient also receive filgrastim (G-CSF) subcutaneously daily beginning 24 hours after the final Bi213 MOAB M195 infusion and continuing until blood counts recover. Treatment continues in the absence of disease progression or unacceptable toxicity. Cohorts of 3 to 6 patients receive escalating doses of Bi213 MOAB M195 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, subsequent patients are treated at the MTD. Patients are followed twice weekly for 4 weeks and then monthly for 3 months.
