• Not expected to start hemodialysis during the study
• Correction group: Not being treated with ESAs for the recent 8 weeks prior to the screening period
• Conversion group: Being treated with ESAs for the recent 8 weeks prior to the screening period

• Fluctuation between the two Hb levels closest in time to the baseline visit during the screening period less than 1.5 g/dL
• Serum ferritin ≥ 100 ng/mL, or TSAT ≥20% during the screening period
• Folate and vitamin B12 ≥ lower limit of normal during the screening period

You may not qualify if:

• Ophthalmic examinations during the screening period correspond to either of the following criteria;
• No available fundal findings
• Findings indicating the presence of active fundal disease
• Severe heart failure (New York Heart Association Class IV)
• Cerebrovascular disorder or acute coronary syndrome (e.g. hospitalization due to unstable angina or myocardial infarction), requiring hospitalization due to urgent percutaneous intervention for coronary or heart failure within 12 weeks prior to the screening period
• New onset or recurrent event of deep vein thrombosis or pulmonary embolism within 12 weeks prior to the screening period
