Participants must meet all the following criteria at screening (unless otherwise specified) to be eligible for enrollment in the study:
Aged ≥18 years at the time of signing informed consent.

Baseline endoscopy at screening with modified Mayo Score for UC and CDAI for Crohn's Disease to include mild disease as defined below:
a. CDAI of <220 and SES-CD of 0 to 6 (CD/IBD-unclassified) modified Mayo Score of <5 points and Mayo endoscopic subscore of 0 to 1 (UC/IBD-unclassified).

Have symptomatic anemia defined as:
Hgb ≤10 g/dL and symptomatic as assessed by Investigator (fatigue, shortness of breath at rest or on minimal exertion, palpitations, tachycardia, orthostatic hypotension or dizziness), or
Hgb >10 g/dL and a minimum score of 4 on the Numeric Rating Scale for Fatigue.

Total and direct bilirubin <ULN at screening.
Estimated glomerular filtration rate ≥30 mL/min/1.73 m2 by the Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) formula.

Stable hormonal contraceptive (≥3 months)
Intrauterine device in place for at least 3 months
Tubal ligation or single male partner with vasectomy
If a male with female sexual partner(s) of childbearing potential, agrees to use 1 of the following highly effective 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)
Intrauterine device in place for at least 3 months (female partner)

You may not qualify if…

Participants meeting any of the following criteria at screening are not eligible for study enrollment:
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 screening labs for oral iron or iron-containing supplements. Between screening and 2 days prior to Day 1 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 any of the following anemia treatments: blood transfusion, EPO-stimulating agent (ESA), or IV iron. Participants may be considered for the study if they undergo a 30-day washout period for ESAs or IV iron prior to screening labs.
Planned change in IBD directed therapy within 3 months of screening.
Moderate or severe IBD assessed during screening period. Defined as:
CD/IBD-unclassified: participants with a CDAI score ≥220 or SES-CD ≥7
UC/IBD-unclassified: modified Mayo Score of ≥6 or endoscopic subscore of 3
Fever, tachycardia, or anticipated need for surgery in the next 3 months
Hospitalization within 30 days prior to screening.
Positive direct antiglobulin test with reactive eluate at screening or medical history at screening of active hemolytic anemia.
Gross gastrointestinal blood loss (eg, visible rectal bleeding, hematochezia, melena) within 4 weeks prior to screening.
Active gastrointestinal bleeding requiring hospitalization, blood transfusion, or endoscopy hemostasis within 8 weeks prior to screening.
Current use of Janus kinase (JAK) inhibitor.
History of hereditary hemochromatosis.
History of Primary Sclerosis Cholangitis.
History of hemoglobinopathy or intrinsic RBC 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 Vitamin B12 or folate deficiency or infection in the 3 months prior to screening.
Stroke, myocardial infarction, deep venous thrombosis, pulmonary or arterial embolism within 6 months prior to screening.
Medical history of clinically significant thrombotic disorder.
If female, pregnant or breastfeeding.
Any major surgery within 8 weeks before screening or incomplete recovery from any previous surgery.
