Inclusion criteria:

Aged ≥18 years of age at the time of signing informed consent.

Hgb <11.0 g/dL
Serum ferritin ≥50 μg/L at screening
Transferrin saturation ≤35%
AST and ALT <2× upper limit of normal (ULN) at screening
Total and direct bilirubin <ULN at screening
If female, then EITHER postmenopausal, defined as at least 12 months of natural, spontaneous amenorrhea and serum follicle-stimulating hormone >40 mIU/mL at screening, or at least 6 weeks following surgical menopause (bilateral oophorectomy or hysterectomy); OR agreeable to use of highly effective contraception (listed below) on Day 1 (or earlier) for at least 8 weeks after the last dose of study drug:

- Tubal ligation or single male partner with vasectomy in conjunction with a barrier method (eg, condom [male or female] or diaphragm)
If male with female sexual partner(s) of childbearing potential, agrees to use one of the following acceptable methods of contraception during the study and for at least 8 weeks after the last study drug dose:
- Stable hormonal contraceptive (≥3 months; female partner) in conjunction with a barrier method (eg, condom or diaphragm [female partner])

Exclusion Criteria:

Treatment within 2 days prior to screening with oral iron or iron-containing supplements. Participants may be considered for the study if they undergo a 2-day washout period prior to signing the informed consent form (ICF) and screening for oral iron or iron-containing supplements. Between screening and 2 days prior to baseline visit, participants may continue oral iron or iron-containing supplements at the discretion of the Investigator, but any study-related lab draws will require a 48-hour washout from oral iron
Treatment within 30 days prior to screening with one of the following anemia treatments: blood transfusion, ESAs, or IV iron. Participants may be considered for the study if they undergo a 30-day washout period prior to signing the ICF and screening for erythropoietin-stimulating agents or IV iron

Hospitalization for a CV, renal, or cardiorenal condition within 30 days prior to screening
Positive direct antiglobulin test with reactive eluate at screening or active hemolytic anemia. This test can be performed prior to other screening procedures after the participant is consented for the prescreening testing
History of hereditary hemochromatosis
History of hemoglobinopathy or intrinsic red blood cell defect associated with anemia
History of total splenectomy
Hematopoietic stem cell or solid organ transplant within the past 10 years
Medical history of anemia from B12 or folate deficiency, infection, or bleeding in the 3 months prior to screening
Stroke, myocardial infarction, deep venous thrombosis, pulmonary or arterial embolism within 6 months prior to screening
If female, pregnant or breastfeeding
Any major surgery within 8 weeks before screening or incomplete recovery from any previous surgery
History of malignancy within the last 3 years. The following history/concurrent conditions are allowed: basal or squamous cell carcinoma skin cancer, carcinoma in situ of the cervix, carcinoma in situ of the breast, histologic finding of prostate cancer (T1a or T1b using the tumor, nodes, metastasis [TNM] clinical staging system). A history of completed treatment (medical or surgical) of Stage 1-2 cancers may be permitted with prior Sponsor agreement
