You may be eligible if
More than or equal to 40 years of age, at the time of signing the informed consent
Stable Hgb 8.5 to 11.5 grams per deciliter (g/dL) inclusive.
Dialysis frequency: On hemodialysis (HD, hemofiltration or hemodiafiltration) three-to five-times weekly for at least 4 weeks prior to screening.
A single pool Kt/Vurea \>=1.2 based on a historical value obtained within 3 months prior to screening in order to ensure the adequacy of dialysis. If Kt/Vurea is not available, then an average of the last 2 values of urea reduction ratio should be at least 65 percent (%).
Treated with an ESA (epoetins or their biosimilars, darbepoetin, or methoxy polyethylene glycol \[PEG\]-epoetin beta) for at least 4 weeks prior to screening.
Participants may be on stable (\<=50% change in overall dose and compliance of 80% of prescribed doses in the 4 weeks prior to and including the screening period) maintenance oral or intravenous (IV; \<=100 mg/week) iron supplementation. If participants are on oral or IV iron, then doses must be stable for the 4 weeks prior to Washout.
Weight: Mid-week weight change between dialysis treatments \<5% as assessed post-dialysis at the Screening and Washout visits.
On at least 1 antihypertensive medication (excluding diuretics) and on that same medication and the same dose for at least 1 week prior to Washout.
Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the consent form and the protocol.
Willing and able to wear ABPM device for at least 25 hours on two separate sessions.
You may not be if
Planned change from HD to peritoneal dialysis within the study time period, or on home dialysis.
Planned for kidney transplant within the 16 weeks following the Screening visit.
An epoetin alfa dose of \>=360 U/kg/week IV or \>=250 U/kg/week subcutaneous (SC), or darbepoetin dose of \>=1.8 micrograms (μg)/kg/week IV or SC, or methoxy PEG-epoetin beta dose of \>=2.2 μg/kg/week within the 8 weeks prior to screening through Week -4.
Planned or recorded administration of Mircera (methoxy PEG-epoetin beta) within the 4 weeks prior to the Washout.
Occurrence of myocardial infarction or acute coronary syndrome within 3 months prior to Washout.
Stroke or transient ischemic attack within 3 months prior to Washout.
Chronic Class 4 heart failure, as defined by the New York Heart Association functional classification system diagnosed prior to Washout.
QT interval corrected for heart rate using Bazett's formula (QTcB) \>500 milliseconds (msec), or QTcB \>530 msec in participants with Bundle Branch Block. There is no QTc exclusion for participants with a predominantly paced rhythm.
Resting post dialysis SBP \>160 millimeters of mercury (mmHg); or DBP \>100 mmHg at screening or uncontrolled hypertension as determined by the investigator.
Presence of atrial fibrillation.
Active chronic inflammatory disease that could impact erythropoiesis (e.g., scleroderma, systemic lupus erythematosus, rheumatoid arthritis, celiac disease) diagnosed prior to Washout.
History of bone marrow aplasia or pure red cell aplasia.
Other causes of anemia including Pernicious anemia, thalassemia major, sickle cell disease or myelodysplastic syndrome.
Alanine transaminase (ALT) \>2 times upper limit of normal (ULN) (screening only) or Bilirubin \>1.5 times ULN (screening only) or Current unstable liver or biliary disease per investigator assessment, generally defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices, persistent jaundice, or cirrhosis.
Major surgery (excluding vascular access surgery) within the 3 months prior to Washout or planned during the study.
Blood transfusion within the 8 weeks prior to Washout or an anticipated need for blood transfusion during the study.
Evidence of actively bleeding gastric, duodenal, or esophageal ulcer disease or clinically significant gastrointestinal bleeding within the 8 weeks prior to Washout.
Clinical evidence of acute infection or history of infection requiring IV antibiotic therapy within the 8 weeks prior to Washout.
History of malignancy within the two years prior to screening through Day 1 or currently receiving treatment for cancer, or has a known complex kidney cyst (e.g., Bosniak Category IIF, III or IV) \>=3 centimeters.
Participants with an upper arm diameter which cannot be measured by oscillometer/ sphygmomanometer cuff or for whom BP cannot be measured in the opposite arm of current vascular access.
History of severe allergic or anaphylactic reactions or hypersensitivity to excipients in the investigational product.
Use of any prescription or non-prescription drugs or dietary supplements that are prohibited from screening until Washout.
The participant has participated in a clinical trial and has received an experimental investigational product within the 30 days prior to Day 1 or within 5 half lives of the investigational product prior to screening, whichever is longer.
Any other condition, clinical or laboratory abnormality, or examination finding that the investigator considers would put the participant at unacceptable risk, which may affect study compliance or prevent understanding of the aims or investigational procedures or possible consequences of the study.
A female participant is pregnant (as confirmed by a positive serum human chorionic gonadotrophin test for females of reproductive potential only), participant is breastfeeding, or participant is of reproductive potential and does not agree to follow one of the pre-specified contraceptive options
Vitamin B12 at or below the lower limit of the reference range (may rescreen in a minimum of 8 weeks, following treatment).
