Eligibility Criteria
Inclusion
- Participants are eligible to be included in the study only if all of the following criteria apply:
- Male participants and female participants who are not of childbearing potential who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, blood pressure, pulse rate and standard 12 lead ECG.
Exclusion
- Participants are excluded from the study if any of the following criteria apply:
- Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing).
- Any of the following conditions: History of iron storage diseases such as hemochromatosis. History of iron utilization disorder such as sideroblastic anemia. Diagnosis of hemolytic anemia or hemoglobinopathy (eg thalassemia). Diagnosis of iron deficiency anemia within 3 months prior to screening. Recent blood donation (within 60 days prior to first dose).
- History of intravenous iron therapy, erythropoiesis stimulating agent therapy (eg erythropoietin) and/or oral iron containing concomitant medications or nutritional supplements exceeding recommended dietary allowances for iron in adults (adult men age 19-50 years: 8 mg, adult women 19-50 years: 18 mg, adults \>50 years: 8 mg on weekly average in the 4 weeks prior to randomization).
- Screening supine BP ≥140 mm Hg (systolic) or ≥90 mm Hg (diastolic) for participants \<60 years; and ≥150/90 mm/Hg for participants ≥60 years old, following at least 5 minutes of supine rest. If systolic BP is ≥ 140 or 150 mm Hg (based on age) or diastolic ≥90 mm Hg, the BP should be repeated 2 more times and the average of the 3 BP values should be used to determine the participant's eligibility.
- An eGFR \<90 mL/min/1.73m², as determined by the CKD-EPI equation using Screat calculated using the recommended formulas
- Standard 12-lead ECG that demonstrates clinically relevant abnormalities that may affect participant safety or interpretation of study results (eg, QTcF \>450 ms, complete LBBB, signs of an acute or indeterminate- age myocardial infarction, ST-T interval changes suggestive of myocardial ischemia, second- or third- degree AV block, or serious bradyarrhythmias or tachyarrhythmias). If QTcF exceeds 450 ms, or QRS exceeds 120 ms, the ECG should be repeated twice and the average of the 3 QTcF or QRS values used to determine the participant's eligibility. Computer-interpreted ECGs should be overread by a physician experienced in reading ECGs before excluding a participant.
- Participants with ANY of the following abnormalities in clinical laboratory tests at screening and prior to dosing in each period, as assessed by the study-specific laboratory and confirmed by a single repeat test, if deemed necessary: ALT, AST, Bilirubin ≥1.05 x ULN. Participants with an elevated total bilirubin consistent with Gilberts Disease may have a direct bilirubin measured and would be eligible for this study provided the direct bilirubin level is ≤ ULN. Hb \<LLN. Serum ferritin \< lower limit of the reference range or \> upper limit of the reference range for the respective gender and (if applicable) menopausal status. High sensitivity CRP ≥ 3x upper limit of the reference range, if suspected by the investigator to be indicative of inflammation. Albuminuria as defined by urine albumin/creatinine ratio \> 30 mg/g. Proteinuria as defined by urine protein/creatinine ratio \>200 mg/g. Presence of ≥1+ blood on urine dipstick or red blood cells on urine microscopy. A single repeat assessment for urine dipstick is allowed and, if negative, prior dipstick result will not be exclusionary.
