A Study to Determine the Safety and Tolerability of AG-236 and How it is Absorbed, Broken Down, and Eliminated From the Body in Healthy Participants

Exclusion Criteria35

• Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, or psychiatric disorder, as determined by the investigator or designee.
• History of malignancy, with the exception of adequately treated non-melanomatous skin carcinoma.
• History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, as determined by the investigator or designee.
• History or presence of iron deficiency or iron deficiency anemia and/or currently receiving oral or parenteral iron supplementation as treatment for those conditions or deemed high risk of iron deficiency as determined by the investigator.
• Males: ferritin <30 nanogram per millilitres (ng/mL) and/or transferrin saturation (TSAT): ≤25%.
• Females: ferritin <30 ng/mL and/or TSAT: ≤20%.
• Fever (oral body temperature >38°C) or symptomatic viral or bacterial infection within 2 weeks prior to screening; evidence of intestinal infection (such as a participant-reported history of gastrointestinal symptoms \[eg, nausea, vomiting, diarrhea\] that are consistent, in the opinion of the investigator, with an acute viral or bacterial process) within 30 days prior to screening.
• Confirmed systolic blood pressure >140 or <90 millilitres of mercury (mmHg), diastolic blood pressure >90 or <50 mmHg, or pulse rate >100 or <40 beats per minute. If any parameter is out of range, measurements should be repeated twice. Participants will be excluded if the average of the 3 measurements are outside of the corresponding reference range.
• Clinically significant abnormality, as determined by the investigator, on ECG performed at screening or check-in or any of the following:
• QT interval corrected for heart rate using Fridericia's formula (QTcF) >450 milliseconds (ms) in males or >470 ms in females, confirmed by calculating the mean of the triplicate values obtained
• history of additional risk factors for torsades de pointes (eg, heart failure, hypokalemia, or family history of long QT syndrome).
• Clinical laboratory values that are outside the normal reference range and are considered clinically significant, as determined by the investigator.
• Clinical laboratory values for hemoglobin (Hb) for males <13.8 grams per decilitres g/dL and females <12.1 g/dL.
• Clinical laboratory values for aspartate aminotransferase (AST), alanine aminotransferase (ALT) and/or total bilirubin >1 × upper limit of normal (ULN).
• Participants will be excluded if a single repeat confirms the result.
• Positive hepatitis panel and/or positive human immunodeficiency virus test.
• Participants whose results are compatible with prior immunization may be included.
• Clinical laboratory value for partial thromboplastin time (PTT) >1 × ULN and/or International Normalized Ratio (INR) >1.2. Participants will be excluded if a single repeat confirms the result.
• Administration of any vaccine within 30 days prior to dosing.
• Use or intend to use during the study duration any prescription medications/products, including hormone replacement therapy, within 28 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 during the study duration any slow-release medications/products considered to still be active within 28 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 during the study duration any nonprescription medications/products including vitamins (including iron-containing multivitamins), minerals, biotin supplements, recreational drugs, or phytotherapeutic/herbal/plant-derived preparations within 28 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 IMP (new chemical entity) in the past 30 days or 5 half-lives of that drug (if known) prior to dosing, whichever is longer.
• Have previously completed or withdrawn from this study or any other study investigating AG-236 and have previously received AG-236.
• Alcohol consumption of >14 units per week for males and females. One unit of alcohol equals 12 ounces (oz) (360 mL) beer, 1½ oz (45 mL) liquor, or 5 oz (150 mL) wine.
• Positive urine drug screen at screening or positive alcohol test result or positive urine drug screen at check-in.
• History of alcoholism or drug/chemical abuse within 2 years prior to check-in.
• Use of tobacco- or nicotine-containing products within 3 months prior to check-in, or positive cotinine at screening or check-in.
• Have special dietary restrictions or inability to consume standard meals as required in the study.
• Receipt of blood products within 2 months prior to check in.
• Donation of blood from 3 months prior to screening, plasma from 2 weeks prior to screening, or platelets from 6 weeks prior to screening.
• Poor peripheral venous access.
• Participants who, in the opinion of the investigator or designee, should not participate in this study.
• Increased risk of thrombosis, as determined by the investigator or designee.
• Clinical laboratory value for homocysteine >1 × ULN.
