Who can join

Age: 18 and older, up to 64. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Females must not be pregnant or lactating.
• Females of childbearing potential must agree to use contraception.
• Body mass index between 18.0 and 32.0 kilogram per meter square (kg/m\^2), inclusive.
• In good health, as determined by no clinically significant findings from medical history, 12-lead electrocardiogram (ECG) and vital sign measurements, and clinical laboratory evaluations (congenital nonhemolytic hyperbilirubinemia [e.g., suspicion of Gilbert's syndrome based on total and direct bilirubin] is not acceptable) at screening and check-in, and from the physical examination at check-in, as assessed by the investigator or designee.
• Able to comprehend and willing to sign the informed consent form (ICF) and abide by the study restrictions.

You may not qualify if…

• Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, ophthalmological (acute angle closure glaucoma), or psychiatric disorder, as determined by the investigator or designee.
• History of significant hypersensitivity, intolerance, or allergy to any relevant drug compound, food, or other substance (ie, allergy to study intervention or excipients [microcrystalline cellulose, croscarmellose sodium, sodium stearyl fumarate, mannitol, magnesium stearate, and the Opadry Blue II film-coat [hypromellose, titanium dioxide, lactose monohydrate, triacetin, and FD\&C Blue #2]]).
• History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs (e.g., cholecystectomy). Uncomplicated appendectomy and hernia repair are allowed.
• Significant acute, new-onset illness (e.g., flu, gastroenteritis) within 2 weeks prior to dosing.
• Confirmed systolic blood pressure >150 or <90 millimeters of mercury (mmHg), diastolic blood pressure >100 or <50 mmHg, or pulse rate >100 or <40 beats per minute (bpm). If any parameter falls outside of the specified range at screening or check-in, 2 repeat measurements will be performed and the participant will be excluded only if the mean of the parameter based on the 3 replicates falls outside of the specified range.
• Clinically significant cardiac history or presence of ECG findings, including any of the following:
• Heart rate <40 bpm or >100 bpm
• Risk factors for torsades de pointes (e.g., heart failure, cardiomyopathy, or family history of long QT syndrome)
• Sick sinus syndrome, second- or third-degree atrioventricular block myocardial infarction, pulmonary congestion, cardiac arrhythmia, prolonged QT interval, or conduction abnormalities
• QT interval corrected for heart rate using Fridericia's formula (QTcF) >450 millisecond (msec) (healthy male participants) or >470 msec (healthy female participants); if QTcF is >450 msec (males) or >470 msec (females), 2 repeat measurements will be performed and the participant will be excluded only if the mean QTcF based on the 3 replicate ECGs is >450 msec (males) or >470 msec (females).
• QRS duration >110 msec, confirmed by manual overread; if value is >110 msec, 2 repeat measurements will be performed and the participant will be excluded only if the mean QRS duration based on the 3 replicate ECGs is >110 msec.
• PR interval <120 or >220 msec, confirmed by manual overread; if value is <120 or >220 msec, 2 repeat measurements will be performed and the participant will be excluded only if the mean PR interval based on the 3 replicate ECGs is <120 or >220 msec.
• Repeated syncope or vasovagal episodes.
• Hypertension, angina, bradycardia (if assessed as clinically significant by the investigator) or severe peripheral arterial circulatory disorders
• History of autonomic dysfunction.
• Positive hepatitis panel and/or positive human immunodeficiency virus test.
• Administration of any vaccine within 30 days prior to dosing.
• Use or intend to use any medications/products known to alter drug absorption, metabolism, or elimination processes, including St. John's wort, within 30 days prior to dosing, considered to potentially impact participant safety or the objectives of the study, as determined by the investigator or designee.
• Use or intend to use any prescription medications/products, other than non-hormonal contraceptives, within 14 days prior to dosing, considered to potentially impact participant safety or the objectives of the study, as determined by the investigator or designee.
• Use or intend to use any slow-release medications/products considered to still be active within 14 days prior to dosing, considered to potentially impact participant safety or the objectives of the study, as determined by the investigator or designee.
• Use or intend to use any nonprescription medications/products including vitamins, minerals, high-dose biotin supplements and other supplements, and phytotherapeutic/herbal/plant-derived preparations within 7 days prior to dosing, considered to potentially impact participant safety or the objectives of the study, as determined by the investigator or designee.
• Participation in a clinical study involving administration of an investigational medicinal product (new chemical entity) in the past 30 days or 5 half-lives of that drug (if known) prior to dosing, whichever is longer.
• Has previously completed or withdrawn from this study or any other study investigating mitapivat and has previously received mitapivat.
• Alcohol consumption of >21 units per week for males and >14 units for females. One unit of alcohol equals 12-ounce (oz) (360 mL) beer, 1½ oz (45 mL) liquor, or 5 oz (150 mL) wine.
• Positive urine drug screen at screening; positive alcohol test result or positive urine drug screen at check-in.
