What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: From first dose up to end of cycle 1 (30 days)
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).
Measured: 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)

Secondary outcomes (51)
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.
Measured: During the first 2 cycles (56 days)
Percentage of Participants With CR During Treatment
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%.

Participants were classified as being in CRi when they 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 and platelet transfusion independence were not required. Exact 95% confidence interval was estimated using the binomial distribution.
Measured: Up to end of treatment (median treatment duration was 69.5 days, minimum of 3 days and maximum of 1320 days)
Percentage of Participants With Complete Remission With Partial Hematologic Recovery (CRh)
CRh 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 CRh when they could not be classified as being in CR and had bone marrow blasts < 5% and partial hematologic recovery ANC >= 0.5 x 10^9/L and platelets >= 50 x 10^9/L.

Percentage of Participants With Partial Remission (PR)
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.
Measured: Up to end of treatment (median treatment duration was 69.5 days, minimum of 3 days and maximum of 1320 days)
Percentage of Participants With Best Response

TTBCRCRh was evaluated for participants who achieved CR or CRh. For participants who achieve both CR and CRh, the first CR date was used. TTBCRCRh was calculated only for participants who were FLT3 mutation positive.
Measured: From first dose of study drug up to end of treatment (median treatment duration was 69.5 days, minimum of 3 days and maximum of 1320 days)
Time to CRc (TTCRc)
TTCRc was defined as the time from the first dose of study drug until the date of first CRc. TTCRc was evaluated for participants who achieved CRc.
Measured: From first dose of study drug up to end of treatment (median treatment duration was 69.5 days, minimum of 3 days and maximum of 1320 days)
Time to Response (TTR)
TTR was defined as the time from the first dose of study drug until the date of either first CRc or PR. TTR was evaluated for participants who achieved CRc or PR.
Measured: From first dose of study drug up to end of treatment (median treatment duration was 69.5 days, minimum of 3 days and maximum of 1320 days)
Time to Best Response (TTBR)
TTBR was defined as the time from the first dose of study drug until the first disease assessment date when participant achieved best response. TTBR was evaluated in participants who achieved best response of CR, CRp, CRi, or PR.
Measured: From first dose of study drug up to end of treatment (median treatment duration was 69.5 days, minimum of 3 days and maximum of 1320 days)
Overall Survival (OS)
The time from the date of first dose of study drug until the date of death from any cause. For a participant who was not known to have died by the end of study follow-up, OS was censored at the date of last contact. OS was calculated using Kaplan-Meier method and therefore data are estimated.
Measured: From first dose of study drug up to end of study (median time on study was 157.0 days, minimum of 5 days and maximum of 1320 days)
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.
Measured: From first dose of study drug up to end of study (median time on study was 157.0 days, minimum of 5 days and maximum of 1320 days)
Leukemia Free Survival (LFS)
LFS was defined as the time from the date of first CRc until the date of documented relapse or death for participants who achieved CRc. For a participant who was not known to have relapsed or died, LFS was censored on the date of last relapse-free disease assessment date. LFS was calculated using Kaplan-Meier method and therefore data are estimated.
Measured: From first dose of study drug up to end of study (median time on study was 157.0 days, minimum of 5 days and maximum of 1320 days)
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.
Measured: 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 Who Achieved Transfusion Maintenance
Participants who achieved transfusion maintenance were defined as the number of participants who were transfusion independent at baseline period and still maintained transfusion independent at post-baseline period divided by the total number of participants who were transfusion independent at baseline period.
Measured: 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

Primary outcome
Number of Participants With Dose Limiting Toxicities (DLTs)
Time frame: From first dose up to end of cycle 1 (30 days)
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.
Number of Participants With Adverse Events (AEs)
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)
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).

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 20 Feb 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Dose Limiting Toxicities (DLTs) (time frame: From first dose up to end of cycle 1 (30 days)). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02014558, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
