Quizartinib or Placebo Plus Chemotherapy in Newly Diagnosed Patients With FLT3-ITD Negative AML

Prior treatment

• Diagnosis of acute promyelocytic leukemia (APL), French-American-British classification M3 or WHO classification of APL with translocation, t(15;17)(q22;q12), or BCR-ABL positive leukemia (ie, chronic myelogenous leukemia in blast crisis); participants who undergo diagnostic workup for APL and treatment with all-trans retinoic acid (ATRA), but who are found not to have APL, are eligible (treatment with ATRA must be discontinued before starting induction chemotherapy).
• Diagnosis of AML secondary to prior chemotherapy or radiotherapy.
• Prior treatment for AML, except for the following allowances prior to Day 1 of chemotherapy:
  • Leukapheresis;
  • Treatment for hyperleukocytosis with hydroxyurea;
  • Cranial radiotherapy for central nervous system (CNS) leukostasis;
  • Prophylactic intrathecal chemotherapy

Other illness

• Diagnosis of AML with known antecedent myelodysplastic syndrome (MDS) or a myeloproliferative neoplasm (MPN) or MDS/MPNs including chronic myelomonocytic leukemia (CMML), atypical chronic myeloid leukemia (aCML), juvenile myelomonocytic leukemia (JMML) and others.

Other

• Participants with newly diagnosed AML with FLT3-ITD mutations (FLT3-ITD \[+\]) present at ≥5% VAF (or ≥0.05 SR) based on a validated FLT3 mutation assay.

• Must be competent and able to comprehend, sign, and date an Ethics Committee (EC)- or Institutional Review Board (IRB)-approved ICF before performance of any trial-specific procedures or tests.
• ≥18 years or the minimum legal adult age (whichever is greater) and ≤70 years (at Screening).
