Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Pharmacokinetics (PK) of gilteritinib in plasma: area under the concentration-time curve from the time of dosing to 72 hours (AUC72)	AUC72 will be recorded from the PK plasma samples collected.	Up to Day 9
Pharmacokinetics (PK) of gilteritinib in plasma: area under the concentration-time curve from the time of dosing extrapolated to time infinity (AUCinf)	AUCinf will be recorded from the PK plasma samples collected.	Up to Day 9
Pharmacokinetics (PK) of gilteritinib in plasma: area under the concentration-time curve from the time of dosing to the last measurable concentration (AUClast)	AUClast will be recorded from the PK plasma samples collected.	Up to Day 9
Pharmacokinetics (PK) of gilteritinib in plasma: maximum concentration (Cmax)	Cmax will be recorded from the PK plasma samples collected.	Up to Day 9

Secondary Outcomes

Measure	Description	Time Frame
Safety and tolerability assessed by nature, frequency, and severity of Adverse Events (AEs)	Adverse Events (AEs) will be coded using medical dictionary for regulatory activities (MedDRA). An AE is any untoward medical occurrence in a participant administered an investigational product (IP) and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of IP whether or not considered related to the IP.

Eligibility Criteria

Inclusion Criteria:

Subject has a body mass index range of 18.5 to 32.0 kg/m2, inclusive and weighs at least 50 kg at screening.
Female subject is not pregnant and the following condition applies:
- Subject is not a woman of childbearing potential.
Male subject with female partner(s) of childbearing potential (including breastfeeding partner[s]) must agree to use contraception throughout the treatment period and for 120 days after study treatment administration.
Male subject must not donate sperm during the treatment period and for 120 days after study treatment administration.
Male subject with pregnant partner(s) must agree to remain abstinent or use a condom for the duration of the pregnancy throughout the study period and for 120 days after study treatment administration.
Subject agrees not to participate in another interventional study while participating in the present study.

Exclusion Criteria:

Subject has received any investigational therapy within 28 days or 5 half-lives, whichever is longer, prior to screening.
Subject has any condition which makes the subject unsuitable for study participation.
Female subject who has been pregnant within 6 months prior to screening assessment or breastfeeding within 3 months prior to screening.
Subject has a known or suspected hypersensitivity to gilteritinib, or any components of the formulations used.
Subject has had previous exposure with gilteritinib.
Subject has any of the liver function tests (alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase and total bilirubin) ≥ 1.5 × upper limit of normal on day -1. In such a case, the assessment may be repeated once.
Subject has any clinically significant history of allergic conditions (including drug allergies, asthma, eczema, or anaphylactic reactions, but excluding untreated, asymptomatic, seasonal allergies) prior to study treatment administration.
Subject has any history or evidence of any clinically significant cardiovascular, gastrointestinal, endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, neurologic, dermatologic, psychiatric, renal and/or other major disease or malignancy.
Subject has/had febrile illness or symptomatic, viral, bacterial (including upper respiratory infection), or fungal (noncutaneous) infection within 1 week prior to day -1.
Subject has any clinically significant abnormality following the investigator's review of the physical examination, electrocardiogram (ECG) and protocol-defined clinical laboratory tests at screening or on day -1.
Subject has a mean pulse < 45 or > 90 bpm; mean systolic blood pressure > 140 mmHg; mean diastolic blood pressure > 90 mmHg (measurements taken in triplicate after subject has been resting in the supine position for at least 5 minutes; pulse will be measured automatically) on day -1. If the mean blood pressure exceeds the limits above, 1 additional triplicate may be taken.
Subject has a mean corrected QT interval using Fridericia's formula (QTcF) interval of > 430 msec (for male subjects) and > 450 msec (for female subjects) on day -1. If the mean QTcF exceeds the limits above, 1 additional triplicate ECG may be taken.
Subject has a history of unexplained syncope, cardiac arrest, unexplained cardiac arrhythmias or torsades de pointes, structural heart disease or a family history of long QT syndrome.
Subject has used any prescribed or nonprescribed drugs (including vitamins and natural and herbal remedies, e.g., St. John's Wort) in the 2 weeks prior to study treatment administration, except for occasional use of paracetamol (up to 2 g/day), topical dermatological products, including corticosteroid products and hormone replacement therapy (HRT).
Subject has smoked, used tobacco-containing products and nicotine or nicotine-containing products (e.g., electronic vapes) within 6 months prior to screening.
Subject has a history of consuming > 14 units for male subjects or 7 units for female subjects of alcoholic beverages per week within 6 months prior to screening or has a history of alcoholism or drug/chemical/substance abuse within 2 years prior to screening (note: 1 unit = 12 ounces of beer, 4 ounces of wine, 1 ounce of spirits/hard liquor) or the subject tests positive for alcohol at screening or on day -1.

Subject has a positive serology test for hepatitis A virus antibodies (immunoglobulin M), hepatitis B core, hepatitis B surface antigen, hepatitis C virus antibodies or antibodies to human immunodeficiency virus type 1 and/or type 2 at screening.
Subject is an employee of Astellas, the study-related contract research organizations or the clinical unit.
