Percentage of Participants With Composite CR (CRc)Up to end of treatment (median treatment duration was 69.5 days, minimum of 3 days and maximum of 1320 days)CRc was defined according to modified Cheson criteria (2003), using centrally evaluated myeloblast counts from bone marrow aspirate/biopsy assessments and centrally evaluated hematology results; if neither central bone marrow aspirate nor biopsy was available, myeloblast was imputed with locally evaluated bone marrow aspirate/biopsy assessments (derived response). Participants were classified as being in CRc when they had achieved either CR, complete remission with incomplete platelet recovery (CRp, defined as had achieved CR except for incomplete platelet recovery (\< 100 x 10\^9/L) or complete remission with incomplete hematologic recovery (CRi, defined as had fulfilled all the criteria for CR except for incomplete hematological recovery with residual neutropenia \< 1 x 10\^9/L with or without complete platelet recovery; RBC platelet transfusion independence not required). Exact 95% confidence interval was estimated using the binomial distribution.
Percentage of Participants With Partial Remission (PR)Up to end of treatment (median treatment duration was 69.5 days, minimum of 3 days and maximum of 1320 days)PR was defined according to modified Cheson criteria (2003), using centrally evaluated myeloblast counts from bone marrow aspirate/biopsy assessments and centrally evaluated hematology results; if neither central bone marrow aspirate nor biopsy was available, myeloblast was imputed with locally evaluated bone marrow aspirate/biopsy assessments (derived response). Participants were classified as being in PR when they had bone marrow regenerating normal hematopoietic cells with evidence of peripheral recovery with no (or only a few regenerating) circulating blasts and with a decrease of at least 50% in the percentage of blasts in the bone marrow aspirate with the total marrow blasts between 5% and 25%. A value of less or equal than 5% blasts was also considered a PR if Auer rods were present. There should be no evidence of extramedullary leukemia. Exact 95% confidence interval was estimated using the binomial distribution.
Percentage of Participants With Best ResponseUp to end of treatment (median treatment duration was 69.5 days, minimum of 3 days and maximum of 1320 days)Best response was defined according to modified Cheson criteria (2003), using centrally evaluated myeloblast counts from bone marrow aspirate/biopsy assessments and centrally evaluated hematology results; if neither central bone marrow aspirate nor biopsy was available, myeloblast was imputed with locally evaluated bone marrow aspirate/biopsy assessments (derived response). BR was defined as the best measured response for all visits (in the order of CR, CRp, CRi, and PR) post-treatment. Participants who achieved the best response of CR, CRp, CRi or PR were classified as responders. Participants who did not achieve at least PR were considered as non-responders. Exact 95% confidence interval was estimated using the binomial distribution.

Recruitment details

This dose-escalation/dose-expansion study was conducted in sites in the United States, France, Germany and Italy. The study had 7 dose-escalation cohorts with ≥3 participants enrolled at each dose level. Following escalation to the next dose cohort, additional participants were enrolled to the dose-expansion cohorts per protocol-specified criteria.

Pre-assignment details

Participants with acute myeloid leukemia (AML) who relapsed after or were refractory to induction or salvage treatment were selected for this study. Five participants were re-enrolled into the dose-expansion cohorts as they discontinued treatment for reasons other than toxicity or disease progression, as long as they met the eligibility criteria.

Number of Participants With Adverse Events (AEs)

Safety was assessed by AEs, which included abnormalities identified during a medical test (e.g. laboratory tests, vital signs, electrocardiogram, etc.) if the abnormality induced clinical signs or symptoms, needed active intervention, interruption or discontinuation of study medication or was clinically significant. A treatment-emergent AE (TEAE) was defined as an AE observed after starting administration of the study drug up to 30 days after last dose of study drug (for participants who underwent hematopoietic stem cell transplantation \[HSCT\]: defined as AEs observed after starting study drug until the last dose before on study HSCT plus 30 days, and AEs that began after resumption of gilteritinib and within 30 days after the last dose of gilteritinib). AEs were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.03 (1-Mild, 2-Moderate, 3-Severe, 4-LifeThreatening, 5-Death).

Time frame: From first dose of study drug up to 30 days after last dose of study drug (median treatment duration was 69.5 days, minimum of 3 days and maximum of 1320 days)

Population: The analysis population was the SAF.

Primary

Number of Participants With Dose Limiting Toxicities (DLTs)

To determine the maximum tolerated dose, safety was assessed by DLTs, defined as any grade ≥ 3 non-hematologic or extramedullary toxicity that occurred within 30 days starting with the first dose taken on day -2, and included the first treatment cycle in the dose escalation phase and in the first treatment cycle (28 days) in the dose expansion phase, that was considered to be possibly or probably related to study drug. Exceptions to this were the following: (1) Alopecia, anorexia or fatigue, (2) Grade 3 nausea and/or vomiting if not required tube feeding or total parenteral nutrition, or diarrhea if not required or prolonged hospitalization that was managed to grade ≤ 2 with standard antiemetic or antidiarrheal medications used at prescribed dose within 7 days of onset, (3) Grade 3 fever with neutropenia, with or without infection, (4) Grade 3 infection.

Time frame: From first dose up to end of cycle 1 (30 days)

Population: The analysis population was the SAF. Only evaluable participants (defined as participants who received at least 80% of the intended dose during cycle 1 \[received at least 23 daily doses in escalation phase or 22 daily doses in expansion phase during cycle 1\] or participants who developed DLT within cycle 1) were included.

Event Free Survival (EFS)

EFS was defined as the time from the date of first dose of study drug until the date of documented relapse, treatment failure or death from any cause, whichever occurred first. For a participant with none of these events, EFS was censored at the date of last relapse-free disease assessment. A participant without post-treatment disease assessment was censored at randomization date. Treatment failure included those participants who discontinued the treatment due to progressive disease or lack of efficacy without a previous response of CR, CRp, CRi or PR. Treatment failure date referred to the start of new anti-leukemia therapy or the last treatment evaluation date when new anti-leukemia therapy date was not available. For participants who were censored, last relapse-free disease assessment date referred to the participant's last disease assessment date. EFS was calculated using Kaplan-Meier method and therefore data are estimated.

Percentage of Participants Who Achieved Transfusion Conversion

Participants who achieved transfusion conversion were defined as the number of participants who were transfusion dependent at baseline period but became transfusion independent at post-baseline period divided by the total number of participants who were transfusion dependent at baseline period. Participants were considered baseline transfusion dependent if there were RBC or platelet transfusions within the baseline period. Participants were considered post-baseline transfusion independent if they were on treatment \>=84 days, and if there was one consecutive 56 days without any RBC or platelet transfusion within post-baseline period. If participants were on treatment \>28 days but \<84 days, and there was no RBC or platelet transfusion within post-baseline period, or on treatment \<=28 days, post-baseline transfusion status was not evaluable. Exact 95% confidence interval was estimated using the binomial distribution.

Time frame: Baseline (28 days prior to first dose until 28 days after the first dose) and postbaseline (from 29 days after first dose date until last dose date); median treatment duration was 69.5 days, minimum of 3 days and maximum of 1320 days

Percentage of Participants With Best Response

Best response was defined according to modified Cheson criteria (2003), using centrally evaluated myeloblast counts from bone marrow aspirate/biopsy assessments and centrally evaluated hematology results; if neither central bone marrow aspirate nor biopsy was available, myeloblast was imputed with locally evaluated bone marrow aspirate/biopsy assessments (derived response). BR was defined as the best measured response for all visits (in the order of CR, CRp, CRi, and PR) post-treatment. Participants who achieved the best response of CR, CRp, CRi or PR were classified as responders. Participants who did not achieve at least PR were considered as non-responders. Exact 95% confidence interval was estimated using the binomial distribution.

Percentage of Participants With Complete Remission and Complete Remission With Partial Hematologic Recovery (CR/CRh)

Participants with CR/CRh were defined as participants who achieved either CR or CRh. Participants with CR had bone marrow regenerating normal hematopoietic cells, achieved a morphologic leukemia-free state, had an ANC \> 1 x 10\^9/L, platelet count ≥ 100 x 10\^9/L, and normal marrow differential with \< 5% blasts, had been RBC and platelet transfusion independent (defined as 1 week without RBC transfusion and 1 week without platelet transfusion). Also, there had been no presence of Auer rods, no evidence of extramedullary leukemia, and blast counts in peripheral blood had been ≤ 2%. Participants with CRh could not be classified as being in CR and had bone marrow blasts \< 5%, partial hematologic recovery ANC \>= 0.5 x 10\^9/L and platelets \>= 50 x 10\^9/L. There should not be evidence of extramedullary leukemia. Exact 95% confidence interval was estimated using the binomial distribution. CR/CRh was calculated only for participants who were FLT3 mutation positive.

Percentage of Participants With Complete Remission (CR) During the First 2 Cycles

CR was defined according to modified Cheson criteria (2003), using centrally evaluated myeloblast counts from bone marrow aspirate/biopsy assessments and centrally evaluated hematology results; if neither central bone marrow aspirate nor biopsy was available, myeloblast was imputed with locally evaluated bone marrow aspirate/biopsy assessments (derived response). Participants were classified as being in CR when they had bone marrow regenerating normal hematopoietic cells, achieved a morphologic leukemia-free state, had an absolute neutrophil count (ANC) \> 1 x 10\^9/L, platelet count ≥ 100 x 10\^9/L, normal marrow differential with \< 5% blasts, had been red blood cell (RBC) and platelet transfusion independent (defined as 1 week without RBC transfusion and 1 week without platelet transfusion), had no presence of Auer rods and no evidence of extramedullary leukemia, and blast counts in peripheral blood had been ≤ 2%. Exact 95% confidence interval was estimated using binomial distribution.

Time frame: During the first 2 cycles (56 days)

Population: Full analysis set (FAS) - consisted of all participants who were enrolled, took at least 1 dose of study drug and who had at least 1 posttreatment data point. Re-enrolled participants and participants from one site due to concerns with this site's GCP compliance were excluded. Participants were summarized under planned reporting groups in the FAS.
