Active comparator: 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; 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.

Experimental: 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.

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.

Active comparator: 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.
