What was measured
LFS: time from the date of first CRc until the date of documented relapse or death for subjects who achieve CRc. For a subject who is not known to have relapsed or died, LFS is censored on the date of last relapse-free disease assessment date. CRc: achieved CR, CRp or CRi. Relapse: leukemic blasts in peripheral blood/ ≥ 25% blasts in bone marrow (BM) aspirate not due to any other cause/reappearance/new appearance of extramedullary leukemia. CR: BM regenerating normal hematopoietic cells, morphologic leukemia-free state, ANC ≥ 1 x 10\^9/L, platelet count ≥ 100 x 10\^9/L, normal marrow differential with \< 5% blasts, and RBC/platelet transfusion independent with no extramedullary leukemia. CRp: achieved CR except incomplete platelet recovery (\< 100 x 10\^9/L). CRi : criteria for CR fulfilled except incomplete hematological recovery with residual neutropenia \< 1 x 10\^9/L with /without complete platelet recovery..
Analysis population: The analysis population was the ITT, with participants with best response of CRc.
Groups in this outcome
Gilteritinib
Participants received 120 mg dose (3 tablets of 40 mg) orally once a day in continuous 28-day cycles, at least 2 hours after or 1 hour before food. Gilteritinib treatment continued until participants met one of the treatment discontinuation criteria. After the end of treatment period, participants were allowed to enter long-term follow up period for up to 3 years for collection of subsequent AML treatment, EuroQol Group-5 Dimension-5 Level Instrument (EQ-5D-5L), remission status and survival (cause of death and date of death). Participants continuing to derive clinical benefit from gilteritinib as assessed by the investigator were allowed to continue the study treatment until a discontinuation criterion was met or if they had completed more than 3 years of treatment.
Salvage Chemotherapy
Participants received chemotherapy in 28-day cycles. Participants on Low-Dose Cytarabine (LoDAC) received 20 mg of cytarabine twice daily by subcutaneous (SC) or intravenous (IV) injection for 10 days. Participants on azacitidine received 75 mg/m\^2 daily by SC or IV injection for 7 days. Participants on LoDAC or azacitidine treatment continued until they met discontinuation criteria. Participants on mitoxantrone, etoposide and intermediate-dose cytarabine (MEC) chemotherapy received mitoxantrone 8 mg/m\^2 daily by IV for 5 days, etoposide 100 mg/m\^2 daily by IV for 5 days and cytarabine 1000 mg/m\^2 daily by IV for 5 days (days 1-5). Participants on fludarabine, cytarabine and granulocyte colony-stimulating factor with idarubicin (FLAG-IDA) chemotherapy received granulocyte-colony stimulating factor (G-CSF) 300 μg/m\^2 daily by SC/IV for 5 days (days 1-5), fludarabine 30 mg/m\^2 daily by IV for 5 days (days 2-6), cytarabine 2000 mg/m\^2 daily by IV for 5 days (days 2-6) and idarubicin 10 mg/m\^2 daily by IV for 3 days (days 2-4). Participants receiving MEC or FLAG-IDA received 1 cycle of therapy and were assessed for response on or after day 15. After the end of treatment period, participants were allowed to enter the long-term follow-up period of up to 3 years for collection of subsequent AML treatment, EQ-5D-5L, remission status and survival (cause of death and date of death).

- Based on the Cox proportional hazards model. Assuming proportional hazards, an HR of \< 1 indicates a reduction in the hazard rate in favor of the gilteritinib arm.
- group Description
- The LFS was analyzed for participants who achieved remission using the stratified log-rank test with strata to control for response to first-line AML therapy and preselected salvage chemotherapy. Duration of LFS was based on Kaplan-Meier estimates.
