Demographics

Ages ≤ 39

Prior therapy

Must have received: 4-drug induction regimen with intrathecal chemotherapy — induction

patients must have completed a 4-drug induction regimen with intrathecal chemotherapy (modified aBFM regimen or equivalent) as per the institutional standard of care

Cannot have received: any other prior therapy for acute leukemia

Exception: emergency therapy (corticosteroids or hydroxyurea) for blast cell crisis, superior vena cava syndrome, or renal failure due to leukemic infiltration of the kidneys; leukapheresis or exchange transfusion to reduce WBC

No additional prior therapy for acute leukemia except emergency therapy (corticosteroids or hydroxyurea) for blast cell crisis, superior vena cava syndrome, or renal failure due to leukemic infiltration of the kidneys. When indicated, leukapheresis or exchange transfusion is recommended to reduce the white blood cell count (WBC).
