Safety and Effectiveness of Quizartinib in Children and Young Adults With Acute Myeloid Leukemia (AML), a Cancer of the Blood

Why are we doing this research?

Quizartinib is an experimental drug. It is not approved for regular use. It can only be used in medical research.
Children or young adults with a certain kind of blood cancer (FLT3-ITD AML) might be able to join this study if it has come back after remission or is not responding to treatment.

ADVL1822-AC220AU202 A PHASE 1/2, MULTI-CENTER, DOSE-ESCALATING STUDY TO EVALUATE THE SAFETY, PHARMACOKINETICS, PHARMACODYNAMICS, AND EFFICACY OF QUIZARTINIB ADMINISTERED IN COMBINATION WITH RE-INDUCTION CHEMOTHERAPY, AND AS A SINGLE-AGENT MAINTENANCE THERAPY, IN PEDIATRIC RELAPSED/REFRACTORY AML SUBJECTS AGED 1 MONTH TO < 18 YEARS (AND YOUNG ADULTS AGED UP TO 21 YEARS) WITH FLT3-ITD MUTATIONS

Who can participate?

Key Inclusion Criteria:

  • Has diagnosis of AML according to the World Health Organization (WHO) 2008 classification with >5% blasts in bone marrow, with or without extramedullary disease
  • Is in first relapse or refractory to first-line high-dose chemotherapy with no more than 1 attempt (1 to 2 cycles of induction chemotherapy) at remission induction - prior HSCT is permitted
  • Has presence of the FLT3-ITD activating mutation in bone marrow or peripheral blood as defined in the protocol
  • Is between 1 month and 21 years of age at the time the Informed Consent/Assent form is signed
  • Has protocol-defined adequate performance status score
  • Has fully recovered from the acute clinically significant toxicity effects of all prior chemotherapy, immunotherapy, or radiotherapy, per protocol guidelines
  • Has protocol-defined adequate renal, hepatic and cardiac functions
  • If of reproductive potential, is permanently sterile or agrees to use highly effective birth control upon enrollment, during the period of therapy, and for 6 months following the last dose of study drug or cytarabine, whichever is later
  • If female of child-bearing potential, tests negative for pregnancy and agrees not to breast feed
  • Participant/legal representative is capable of understanding the investigational nature of the study, potential risks, and benefits, and the patient (and/or legal representative) signs a written assent/informed consent
  • Meets protocol-specified guidelines before inclusion in the continuation therapy phase

Key Exclusion Criteria:

  • Has been diagnosed with isolated central nervous system relapse, certain kinds of leukemia, or with myeloid proliferations related to Down syndrome
  • Has uncontrolled or pre-defined significant cardiovascular disease as detailed in the protocol
  • Has systemic fungal, bacterial, viral or other infection that is exhibiting ongoing signs/symptoms related to the infection without improvement despite appropriate antibiotics or other treatment. The patient must be off vasopressors and have negative blood cultures for at least 48 hours prior to the start of systematic protocol therapy.

  • Has history of hypersensitivity to any of the study medications or their excipients
  • Is receiving or is anticipated to receive concomitant chemotherapy, radiation, or immunotherapy other than as specified in the protocol
  • Has any significant concurrent disease, illness, psychiatric disorder or social issue that would compromise subject safety or compliance, interfere with consent/assent, study participation, follow up, or interpretation of study results
  • Is currently participating in another investigative interventional procedure (observational or long-term interventional follow-up is allowed)
