Chronic Kidney Disease
About this trial
This is an interventional basic science trial for Chronic Kidney Disease focused on measuring Dialysis, CKD
Eligibility Criteria
Inclusion Criteria:
- Serum concentration of erythropoietin (EPO): <50 mIU/mL at screening test 1, 2, or 3
- Transferrin saturation ≥ 20% or ferritin ≥ 100 ng/mL at screening test 1
Subjects meeting any of the following criteria
- Subjects who has not used erythropoiesis-stimulating agent (ESA) ≥ eight weeks from screening test 1
- Subjects who has used ESA, other than epoetin beta pegol, ≥ four weeks from screening test 1 and has met all of the following criteria A) to C).
A)The total ESA dosage for each week could be changed within a range of 50%, compared to the total ESA dosage for one week before screening test 1, for four weeks before screening test 1 B)Acceptable to discontinue ESA the day following screening test 1 to Follow-up 2 C)The fluctuating range of Hb concentration between screening tests 1 and 2 is within ±0.5 g/dL per week (the same criteria applied between screening test 2 and 3)
- Subjects who receive an explanation about the study before participating in the study and can understand the contents and are willing and able to provide written consent.
<Criteria for ND subjects>
- CKD subjects who never received dialysis and do not need to receive dialysis during the study period.
- Subjects with an Hb concentration at screening test 1 (ESA present at screening test 2) ≥ 10.0 g/dL to < 13.0 g/dL.
- Subjects with an eGFR at screening test 1 ≥ 15 mL/min/1.73m^2 to < 45 mL/min/1.73m^2.
<Criteria for HD subjects>
- Subjects who received hemodialysis (including diafiltration) three times per week ≥ 12 weeks from acquisition consent.
- Subjects with an Hb concentration at screening test 1 (ESA present at screening test 2) ≥ 10.0 g/dL to < 12.0 g/dL.
Exclusion Criteria:
