In select cases presenting with conversion of MRD from negative to positive, treatment with GO may be allowed where no alternative treatments are feasible.


  • Confirmed diagnosis of relapsed or refractory APL with persisting or rising leukemic burden (either by morphology, cytogenetic analysis or by molecular techniques), and no other comparable or satisfactory alternative therapy available.
  • Documentation that malignant cells express CD33

4) Age >=3 months
