Purpose:

RATIONALE: Monoclonal antibodies such as gemtuzumab ozogamicin can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Cyclosporine may increase the effectiveness of gemtuzumab ozogamicin by making cancer cells more sensitive to the drug. Combining gemtuzumab ozogamicin with cyclosporine may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving gemtuzumab ozogamicin together with cyclosporine works in treating older patients with relapsed acute myeloid leukemia.


Study summary:

OBJECTIVES: Primary - Determine the efficacy of gemtuzumab ozogamicin and cyclosporine, in terms of the complete remission rate, in older patients with relapsed acute myeloid leukemia. - Determine the toxicity and pharmacokinetics of this regimen in these patients. Secondary - Correlate clinical response with laboratory studies of drug susceptibility in patients treated with this regimen. OUTLINE: Patients receive cyclosporine IV continuously over 72 hours on days 1-3 and 15-17. Eight hours after initiation of each cyclosporine infusion, patients receive gemtuzumab ozogamicin IV over 2 hours on days 1 and 15. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients are followed for survival. PROJECTED ACCRUAL: A total of 25-50 patients will be accrued for this study within 3 years.
