Anemia, Renal Insufficiency, Chronic

- Subject with end-stage kidney disease (ESKD) on dialysis (including, hemodiafiltration, hemodialysis, and other modalities except for peritoneal dialysis) weekly or more than weekly
- Body weight > 40 and ≤ 160 kg at screening
- Male or female subject ≥ 20 years of age at screening
- At least one kidney
- Not treated with ESAs and/or HIF-PH inhibitors within 8 weeks prior to randomization. However, in case of the patient washed out from ESAs, when the mean Hb (at least 2 central laboratory measurements must be taken ≥ 2 days apart before dialysis) has decrease to ≥ 0.5 dL from the Hb level (central laboratory measurement, before dialysis) after the last ESA administration, AND the interval from the last ESA administration to the study drug assignment was over 1 week for epoetin-alpha, 2 weeks for darbepoetin alpha or 4 weeks for epoetin beta pegol
- Mean of the last 2 Hb level (central laboratory measurement, before dialysis) during the screening period must be ≥ 8.0 and < 10.0 g/dL (2 measurements must be taken ≥ 2 days apart and the difference between the 2 measurements must be < 1.2 g/dL) with the last screening Hb measurement within 14 days prior to study drug assignment
- Ferritin ≥ 50 ng/mL at screening

- New York Heart Association (NYHA) Class III or IV congestive heart failure
- History of cardio- (cerebro-) vascular events (e.g., unstable angina, myocardial infarction, stroke, pulmonary thromboembolism, and acute limb ischemia) within 6 months prior to randomization
- Sustained and poorly controlled arterial hypertension (defined as systolic BP≥ 180mmHg or diastolic BP ≥ 110mmHg) or hypotension (defined as systolic BP < 90mmHg) at randomization
- Proliferative choroidal or retinal disease, such as neovascular age-related macular degeneration or proliferative diabetic retinopathy requiring invasive treatment (e.g., intraocular injections or laser photocoagulation)
