S0106 Cytarabine and Daunorubicin w/ or w/o Gemtuzumab Followed By HD Cytarabine and Either Gemtuzumab or Nothing in de Novo AML

Official Title:

A Phase III Study of the Addition of Gemtuzumab Ozogamicin (Mylotarg®) During Induction Therapy Versus Standard Induction With Daunomycin and Cytosine Arabinoside Followed by Consolidation and Subsequent Randomization to Post-Consolidation Therapy With Gemtuzumab Ozogamicin (Mylotarg®) or No Additional Therapy For Patients Under Age 61 With Previously Untreated De Novo Acute Myeloid Leukemia (AML)

Summary

RATIONALE: Drugs used in chemotherapy, such as cytarabine and daunorubicin, work in different ways to stop cancer cells from dividing so they stop growing and die. 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. Combining chemotherapy with gemtuzumab ozogamicin may kill more cancer cells. It is not yet known whether induction therapy using cytarabine and daunorubicin is more effective with or without gemtuzumab ozogamicin or whether postconsolidation therapy using gemtuzumab ozogamicin is more effective than no additional therapy in treating de novo (first occurrence) acute myeloid leukemia.

PURPOSE: This randomized phase III trial is comparing two different regimens of chemotherapy and monoclonal antibody therapy to see how well they work in treating patients with previously untreated de novo acute myeloid leukemia.
