入选标准

  • Inclusion criteria for trial entry and Randomisation 1 (induction chemotherapy randomisation):
  • - A diagnosis of AML/high risk myelodysplastic syndrome (MDS)/isolated myeloid sarcoma (either de novo or secondary)
  • - Age <18 years
  • - No prior chemotherapy or biological therapy for AML other than that permitted in the protocol
  • - Normal cardiac function (fractional shortening =28% or ejection fraction =55%)
  • - Fit for protocol chemotherapy
  • - Documented negative pregnancy test for female patients of childbearing potential
  • - Patient agrees to use effective contraception (patients of childbearing potential)
  • - Written informed consent from the patient and/or parent/legal guardian
  • Inclusion criteria for participation in the gemtuzumab ozogamicin dose finding study:
  • - Patients meets the inclusion criteria for trial entry
  • - Age =12 months for the major dose finding study
  • - Age = 12 weeks and <12 months for the minor dose finding study
  • - Karnofsky or Lansky performance score of =50
  • - Normal renal function defined as calculated creatinine clearance =90ml/min/1.73m2
  • - Normal hepatic function defined as total bilirubin =2.5 upper limit of normal (ULN) for age unless it is caused by leukaemic involvement or Gilbert’s syndrome or similar disorder
  • - ALT or AST =10 x ULN for age
  • - Written informed consent from the patient or parent/legal guardian
  • Inclusion criteria for participation in R3:
  • - Patient meets the inclusion criteria for trial entry
  • - Induction treatment as per MyeChild 01 protocol or treated with 2 courses of mitoxantrone & cytarabine off trial
  • - Minimal residual disease (MRD) response (performed in MyeChild 01 centralised laboratories, see national MyeChild 01 Laboratory Manual):
  • 1) Patients with good risk cytogenetics/molecular genetics and a MRD level <0.1% by flow after course 2, or a decrease in transcript levels of >3 logs after course 2 for those with an informative molecular marker but without an informative marker of sufficient sensitivity for flow MRD monitoring
  • 2) Patients with intermediate risk cytogenetics/molecular genetics with a MRD level <0.1% by flow after course 1 and course 2, or a decrease in transcript levels of >3 logs after course 1 and course 2 for those with an informative molecular marker, but without an informative marker of sufficient sensitivity for flow MRD monitoring
  • - Written informed consent from the patient and/or parent/legal guardian
  • Inclusion criteria for participation in R4:
  • - Patient meets the eligibility criteria for trial entry
  • - Induction treatment as per MyeChild 01 protocol or treated with 1 or 2 courses of mitoxantrone & cytarabine ± treatment intensification with FLA-Ida off trial
  • - Patient is in CR or CRi defined as <5% blasts confirmed by flow cytometry//molecular/FISH in a bone marrow aspirate taken within 6 weeks prior to randomisation to R4.
  • - Patient meets one of the following criteria and is a candidate for haemopoeitic stem cell transplant (HSCT) as per the protocol:
  • 1) High risk after course 1 (all patients with poor risk cytogenetics and patients with intermediate risk cytogenetics who fail to achieve CR/CRi)
  • 2) Intermediate risk cytogenetics with MRD >0.1% after course 1 and 2 measured by flow. If no flow MRD marker of sufficient sensitivity is identified, a molecular MRD marker with a sensitivity of >0.1% may be used
  • 3) Good risk cytogenetics with flow MRD >0.1% confirmed by a decrease in molecular MRD of <3 logs or rising transcript levels after co

  • - Relapsed or refractory AML
  • - Bone marrow failure syndromes
  • - Prior anthracycline exposure which would inhibit the delivery of study anthracyclines
  • - Concurrent treatment or administration of any other experimental drug or with any other biological therapy for AML
