You may qualify if…

Male and female participants 18 to 55 years of age (inclusive), with a body mass index (BMI) of 18 kg/m\^2 to 32 kg/m\^2 (inclusive) and with a minimum body weight of 45 kg at Screening.
In females, documented surgical sterilization, postmenopausal status for at least 1 year (follicle stimulating hormone [FSH] > 40 million international (mIU)/mL serum at Screening), or agreement to use an approved form of contraception
In males, agreement to avoid sperm donation for 6 months days after the dose of quizartinib
Participants must agree to refrain from donation of blood from 56 days prior to Screening, plasma from 2 weeks prior to Screening, and platelets from 6 weeks prior to Screening.
Liver function test results must be below the upper limit of normal. Hemoglobin levels must be ≥ 11.5 g/dL for female participants and ≥ 12.5 g/dL for male participants.
All participants must be willing to refrain from consuming grapefruit/grapefruit juice, Seville oranges, and pomegranates/pomegranate juice 10 days before the dose of the study drug is given on Day 1 until end-of-study.

You may not qualify if…

Any serious and/or unstable pre-existing medical, psychiatric disorder, or other conditions (including lab abnormality) that could interfere with participant's safety, obtaining informed consent or compliance to the study procedures.
Laboratory results (serum chemistry, hematology, and urinalysis) outside the normal range, if considered clinically significant by the investigator. Estimated glomerular filtration rate (eGFR) < 90 mL/min at screening.
Women who are pregnant or breastfeeding
Use of any drugs or substances known to be inhibitors or inducers of CYP3A4/5 within 28 days from the first dose or 5 half-lives, if known, of the drugs or substances, whichever is greater, prior to quizartinib administration and during the study.
Receipt of any prescribed or over-the-counter (OTC) systemic, herbal (including St John's wort), or topical medication within 14 days of quizartinib administration, or any expectation of requiring use of such medication while participating in the study is prohibited.
Presence or history of clinically severe adverse reaction to any drug
History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs (with the exception of appendectomy, hernia repair, and/or cholecystectomy)
A positive drugs of abuse screen from a urine ethanol test (unless the drug is medically prescribed by a licensed health care provider) or alcohol breath test at Screening or at Check-in on Day -1 or a participant who will not agree to smoke ≤10 cigarettes or equivalent per day from Screening up to Enrollment, and is unable to be restricted to ≤5 cigarettes per day and for 6 hours post dose during their period of residence in the clinical unit
Concomitant use of medications known to affect the elimination of serum creatinine (e.g., trimethoprim or cimetidine) and inhibitors of renal tubular secretion (eg, probenecid) within 14 days or 5 half-lives, if known, of the drugs, whichever is greater, prior to quizartinib administration
History or presence of an abnormal electrocardiogram (ECG), which, in the investigator's opinion, is clinically significant and/or a QT interval corrected for heart rate using Fridericia's formula >450 milliseconds (ms) at Screening.
Use of drugs with a risk of QT interval prolongation or torsade de pointes within 14 days of Day -1 (or 5 drug half-lives, if 5 drug half-lives are expected to exceed 14 days)
Consumption of alcohol- and caffeine-containing beverages within 72 hours prior to check-in and during confinement
Positive serology for hepatitis B surface antigen (HBsAg) and hepatitis C virus [HCV] (healthy participants), hepatitis A virus (HAV) immunoglobulin M, or anti-human immunodeficiency virus (HIV) Type 1 and Type 2 (all subjects)
Current enrollment in or have not yet completed at least 30 days or 5 elimination half-lives, whichever is longer, since receiving an investigational device or product, or receipt of other investigational agents within 30 days of quizartinib
