Nonmyeloablative Preparative Regimen Using Mylotarg for Patients With High Risk Acute Myeloid Leukemia (AML), Acute Lymphocytic Leukemia (ALL), Chronic Myeloid Leukemia (CML) and Myelodysplastic Syndrome (MDS)

• Status: Terminated
• Trial end date: 2004-11-01
• Target enrollment: 0
• Participant gender: All

Summary

Primary Objective:

To determine the safety and maximum tolerated dose of CMA-676 as part of an intensive but nonmyeloablative preparative regimen in older or medically infirm patients undergoing mini-allogeneic peripheral blood stem cell transplantation

Secondary Objectives:

1. To evaluate response rates, engraftment kinetics and degree of chimerism achievable with this strategy.

2. To evaluate disease-free and overall survival and relapse rates.

3. To evaluate the need and ability to give multiple cycles of Mylotarg plus FA and mobilized DLI in patients not achieving complete remission.

• Phase: Phase 2/Phase 3

Criteria

Inclusion Criteria:

• Patients 12-75 years of age

• Patients are eligible if deemed ineligible for conventional high dose chemotherapy programs because of concurrent medical conditions. Patients with refractory AML are eligible provided ejection fraction >= 35%; FEV1, FVC, or DLCO >= 40%; GPT < 3 x normal, direct bilirubin < 2.

• Patients must have recovered from previous Grade III-IV toxicity due to prior antineoplastic therapy (except alopecia).

• Patients with AML with induction failure, relapse or 2nd remission

• Patients with MDS with IPI INT-2 or High-risk disease or CMML.

• Patients with CML in accelerated phase or blast crisis

• Patients with ALL with induction failure, relapse or 2nd remission

• Patients receiving prior BMT are eligible. If myeloablative chemoradiotherapy was used in the prior transplant patients must be >90 days from transplant. If non-myeloablative therapy was used patients must be >30 days post-transplant.

• Leukemia cells must express cell surface CD33 evaluated by flow cytometry in > 20% of leukemia cells.

• Patients must have an HLA identical related donor capable of donating G-CSF stimulated peripheral blood stem cells using apheresis techniques. If patient has a contraindication to PBSC collection bone marrow can be used.

• Patients must have a Zubrod PS <2, Cr <2.0, direct bilirubin <2, and transaminases SGPT <3x normal

• Patients must have an estimated life expectancy > 3 months

• Patient and donor must sign informed consent

Exclusion Criteria:
