E.2 Objective of the trial |
E.2.1 | Main objective of the trial |

|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
*Diagnosis of anemia of chronic kidney disease (CKD) *Diagnosis of non-dialysis-dependent (NDD) CKD with an estimated glomerular filtration rate of greater than (>) 10 and less than (<) 60 milliliters/minute/1.73 meters^2 (mL/min/1.73 m^2) or diagnosis of dialysis dependent (DD) CKD *Mean screening hemoglobin (Hb) <10.0 grams/deciliters (g/dL) *Transferrin Saturation ≥ 20% |
|
E.4 | Principal exclusion criteria |
*Anemia due to a cause other than CKD *Active bleeding or recent clinically significant blood loss *History of sickle cell disease, myelodysplastic syndromes, bone marrow fibrosis, hematologic malignancy, myeloma, hemolytic anemia, thalassemia, or pure red cell aplasia *Red Blood Cells transfusion within 4 weeks *Serum albumin level less than 2.5 g/dL *Uncontrolled hypertension *Active malignancy or treatment for malignancy within the past 2 years prior to Screening *Evidence of iron overload or diagnosis of hemochromatosis *Known hypersensitivity to vadadustat or any excipients in vadadustat tablet |

|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Efficacy timepoints : Weeks 21 to 28 inclusive |
|
E.5.2 | Secondary end point(s) |
Efficacy endpoints : *Time to achieve Hb ≥10.0 g/dL *Proportion of subjects with mean Hb values within the target (≥10.0 to <12.0 g/dL) during the Primary Evaluation Period (Weeks 21 to 28) *Proportion of subjects with mean Hb values within the target (≥10.0 to <12.0 g/dL) during the Extension Period (Weeks 29 to 52) Safety and Tolerability endpoints: *Frequency and severity of AEs, SAEs, and discontinuation from the study due to AEs *Clinically significant changes from Baseline on vital signs, body weight, height, clinical laboratory tests (hematology, serum chemistry, iron indices), and ECG *Adrenal function assessed by adrenocorticotropic hormone (ACTH) stimulation testing and/or morning (AM) cortisol levels PK/PD endpoints: *Determination of plasma concentrations of vadadustat and metabolites for estimation of PK parameters. A population PK (POPPK) model may be constructed and, if so, reported separately. *Changes in serum EPO, reticulocyte count, and Hb as indices of HIF activity Exploratory endpoints: *Mean change from Baseline to Primary Evaluation Period and End of Treatment (EOT) Visit or Early Termination (ET) Visit in Pediatric Quality of Life Inventory™ (PedsQL) 4.0 Generic Core scores for all subjects and/or parent/legal guardian and for PedsQL 3.0 endstage renal disease (ESRD) Module scores in dialysis subjects and/or parent/legal guardian *Change in biomarkers hepcidin and vascular endothelial growth factor (VEGF) |
