Que mesure l'étude ?

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Mean Change From Baseline in Hemoglobin (Hgb) on Day 29
Délai: Baseline; Day 29
Blood samples were collected to assess Hgb. Baseline Hgb was defined as the average of the 2 samples obtained prior to dosing (Pre-Baseline and Baseline). A positive change from baseline indicates that hemoglobin concentration increased.
Baseline; Day 29

Mesure des résultats
Description de la mesure
Délai
Mean Change From Baseline in Hematocrit on Day 29
Délai: Baseline; Day 29
Blood samples were collected to assess hematocrit. A positive change from baseline indicates hematocrit concentration increased.
Baseline; Day 29
Mean Change From Baseline in Total Red Blood Cell (RBC) Count on Day 29
Délai: Baseline; Day 29
Blood samples were collected to assess RBC count. Baseline RBC count was defined as the average of the 2 samples obtained prior to dosing (Pre-Baseline and Baseline). A positive change from baseline indicates RBC count increased.
Baseline; Day 29
Mean Change From Baseline in Absolute Reticulocyte Count on Day 29
Délai: Baseline; Day 29
Blood samples were collected to assess reticulocyte count. Baseline absolute reticulocyte count was defined as the average of the 3 reticulocyte counts obtained prior to dosing (Screening, Pre- Baseline, and Baseline). A positive change from baseline indicates absolute reticulocyte count increased.
Baseline; Day 29
Mean Change From Baseline in Reticulocyte Hemoglobin (Hgb) Content on Day 29
Délai: Baseline; Day 29
Blood samples were collected to assess reticulocyte Hgb. Baseline Hgb was defined as the average of the 2 samples obtained prior to dosing (Pre-Baseline and Baseline). A positive change from baseline indicates reticulocyte Hgb content increased.
Baseline; Day 29
Number of Participants With Absolute Change From Baseline in Hemoglobin (Hgb) at Day 29
Délai: Day 29
Blood samples were collected to assess Hgb. Baseline Hgb was defined as the average of the 2 samples obtained prior to dosing (Pre-Baseline and Baseline).
Day 29
Number of Participants With the Percentage Change From Baseline in Hemoglobin (Hgb) at Day 29
Délai: Day 29
Blood samples were collected to assess Hgb. Baseline Hgb was defined as the average of the 2 samples obtained prior to dosing (Pre-Baseline and Baseline).
Day 29
Number of Participants With Percentage Change From Baseline in Hematocrit at Day 29
Délai: Day 29
Blood samples were collected to assess hematocrit.
Day 29
Number of Participants With Percentage Change From Baseline in Red Blood Cell (RBC) Count at Day 29
Délai: Day 29
Blood samples were collected to assess RBC count. Baseline RBC count was defined as the average of the 2 samples obtained prior to dosing (Pre-Baseline and Baseline).
Day 29
Number of Participants With Change From Baseline in Absolute Reticulocyte Count at Day 29
Délai: Day 29
Blood samples were collected to assess reticulocyte count. Baseline absolute reticulocyte count was defined as the average of the 3 reticulocyte counts obtained prior to dosing (Screening, Pre- Baseline, and Baseline).

Up to 2 weeks post 28 days of treatment
Number of Participants With Clinically Significant Changes From Baseline in Vital Sign Values

Number of Participants With Clinically Abnormal 12-Lead Electrocardiogram (ECG) Findings
Délai: Up to 2 weeks post 28 days of treatment
A standard 12-lead ECG was performed following dosing in a supine position for approximately 10 minutes. ECGs were taken prior to blood draws when possible. The investigator was responsible for reviewing laboratory results for clinical significance.
Up to 2 weeks post 28 days of treatment
Mean Change From Baseline in PR Interval, QT Interval, QRS Interval, and QT Corrected (QTc) Interval
Délai: Up to 2 weeks post 28 days of treatment
A standard 12-lead ECG was performed following dosing in a supine position for approximately 10 minutes. ECGs were taken prior to blood draws when possible. The parameters evaluated from the participant ECG trace included PR interval, QT interval, QRS interval, and QTc (corrected).

Mean Trough Concentrations of Vadadustat at Day 8, 15, 22 and 29
Délai: Pre-dose at Day 8, 15, 22 and 29
Serum samples were collected from the participants at the defined time points. Trough concentration was defined as the concentration of drug in the blood immediately before the next dose is administered. Trough concentration was calculated using the validated liquid chromatography-mass spectrometry (LC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) method
Pre-dose at Day 8, 15, 22 and 29
