What was measured

The Kaplan-Meier method will be used to calculate estimates of OS. Analysis of OS of Down syndrome patients will be performed separately. Monitoring for efficacy of GMTZ with respect to OS and EFS will utilize monitoring based on the Lan-DeMets criterion with α-spending function αt\^2 (truncated at 3 standard deviations) and 2.5% type I error.

Analysis population: Ineligible patients are excluded from analyses of Overall Survival and Event Free Survival.

Groups in this outcome

Arm A: Standard Arm - No GMTZ, AML Pts w/Out Down Syndrome

Patients receive intrathecal (IT) cytarabine (ARA-C) at diagnosis or on day 1 of treatment or twice a week for up to 6 doses. They also receive an infusion of ARA-C on days 1-10; a 6-hour infusion of daunorubicin hydrochloride on days 1, 3, and 5; and a 4-hr infusion of etoposide on days 1-5. After 3 weeks of rest, patients receive IT ARA-C on day 1. They also receive an infusion of ARA-C on days 1-8; a 6-hr infusion of daunorubicin on days 1, 3, and 5; and a 4-hr infusion of etoposide on days 1-5. After 3 weeks of rest, some patients receive IT ARA-C on day 1 and 1-hr infusions of ARA-C and etoposide on days 1-5. After 3 weeks of rest, some patients receive IT ARA-C on day 1; a 2-hr infusion of ARA-C on days 1-4; and a 1-hour infusion of mitoxantrone on days 3-6. After 3 weeks of rest, they receive a 3-hr infusion of ARA-C on days 1, 2, 8, and 9 and an injection of asparaginase on days 2 and 9.

Arm B: Experimental - With GMTZ, AML Pts w/Out Down Syndrome

Pts receive IT ARA-C at diagnosis or on day 1 of treatment or twice a week for up to six doses. They also receive an infusion of ARA-C on days 1-10; a 6-hr infusion of daunorubicin on days 1, 3, \& 5; a 4-hr infusion of etoposide on days 1-5; and a 2-hr infusion of GMTZ - gemtuzumab ozogamicin (Mylotarg) on day 6. After 3 wks of rest, patients receive IT ARA-C on day 1. They also receive an infusion of ARA-C on days 1-8; a 6-hr infusion of daunorubicin on days 1, 3, and 5; and a 4-hr infusion of etoposide on days 1-5. After 3 weeks of rest, some patients receive IT ARA-C on day 1 and 1-hr infusions of ARA-C and etoposide on days 1-5. After 3 wks of rest, some patients receive IT ARA-C on day 1; a 2-hr infusion of ARA-C on days 1-4; and a 1-hr infusion of mitoxantrone hydrochloride on days 3-6. They also receive a 2-hr infusion of gemtuzumab on day 7. After 3 weeks of rest, they receive a 3-hr infusion of ARA-C on days 1, 2, 8, and 9 and an injection of asparaginase on days 2 and 9.

Arm A: Standard Arm - No GMTZ, AML Patients With Down Syndrome

Patients receive intrathecal (IT) cytarabine (ARA-C) at diagnosis or on day 1 of treatment or twice a week for up to 6 doses. They also receive an infusion of ARA-C on days 1-10; a 6-hour infusion of daunorubicin hydrochloride on days 1, 3, and 5; and a 4-hr infusion of etoposide on days 1-5. After 3 weeks of rest, patients receive IT ARA-C on day 1. They also receive an infusion of ARA-C on days 1-8; a 6-hr infusion of daunorubicin on days 1, 3, and 5; and a 4-hr infusion of etoposide on days 1-5. After 3 weeks of rest, some patients receive IT ARA-C on day 1 and 1-hr infusions of ARA-C and etoposide on days 1-5. After 3 weeks of rest, some patients receive IT ARA-C on day 1; a 2-hr infusion of ARA-C on days 1-4; and a 1-hour infusion of mitoxantrone on days 3-6. After 3 weeks of rest, they receive a 3-hr infusion of ARA-C on days 1, 2, 8, and 9 and an injection of asparaginase on days 2 and 9.
