Criteria
Inclusion Criteria:

- Receiving dialysis for ESRD for ≥3 months. Incident dialysis participants (under
Amendment 1 and 2) receiving dialysis for ESRD for ≥ 2 weeks but ≤ 4 months at the
time of randomization

- Participants must be on ESA for ≥ 8 weeks prior to screening; incident dialysis
participants must be on ESA for ≥ 4 weeks prior to screening.

- Mean of the 3 most recent central lab Hb values during the Screening Period must be ≥
9.0 g/dL and ≤ 12.0 g/dL (for incident dialysis participants, mean of the 2 most
recent Hb values must be ≥ 8.5 g/dL and ≤ 12.0 g/dL); with an absolute difference of ≤
1.3 g/dL between the highest and the lowest value. Samples are obtained at least 4
days apart (2 days under Amendment 2) and the last Hb value must be within 10 days
prior to the randomization visit

- Participants with ferritin level ≥ 100 nanograms (ng)/milliliter (mL) (<100 ng/mL
under Amendment 2) or transferrin saturation (TSAT) ≥ 20% (<20% under Amendment 2) at
screening may qualify upon receiving iron supplement (per local standard of care)

- Participants with a serum folate and Vitamin B12 ≥ lower limit of normal (LLN) (< LLN
under Amendment 2) at screening may qualify upon receiving supplement (per local
standard of care)

- Participant's alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are
≤3x the upper limit of normal (ULN), and total bilirubin (TBL) is ≤1.5x ULN at
screening

- Participant's body weight is 45 kilograms (kg) to 160 kg.

Exclusion Criteria:

- Participant has received an red blood cell (RBC) transfusion within 8 weeks (4 weeks
under Amendment 2) prior to randomization

- Participant has known history of myelodysplastic syndrome or multiple myeloma

other known causes for anemia other than chronic kidney disease.

- Participant has known hemosiderosis, hemochromatosis, coagulation disorder,or
hypercoagulable condition

- Participant has known chronic inflammatory disease that could cause anemia

- Participant has anticipated surgery that is expected to cause blood loss

- Participant has known gastrointestinal bleeding

hepatitis,chronic auto-immune liver disease,cirrhosis, or fibrosis of the liver)

- Participant with New York Heart Association (NYHA) Class III or IV congestive heart
failure

event (for example, deep vein thrombosis or pulmonary embolism) within 12 weeks prior
to participating in the study

- Participant has uncontrolled high blood pressure within 2 weeks prior to participating
in the study

- Participant has a history of malignancy, except for the following: cancers determined
to be cured or in remission for ≥2 years, curatively resected basal cell or squamous
cell skin cancers, cervical cancer in situ, or resected colonic polyps.)

- Participant is positive for human immunodeficiency virus (HIV), Hepatitis B surface
antigen, or anti-hepatitis C virus antibody

- Participant with prior organ transplant who experience rejection within 6 months or on
high doses of immunosuppressive therapy

- Participant has any of the following known untreated conditions; proliferative
diabetic retinopathy, diabetic macular edema, macular degeneration or retinal vein
occlusion.
