Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Mean Change From Baseline in Hemoglobin (Hgb) on Day 29
Lasso di tempo: 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

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Mean Change From Baseline in Hematocrit on Day 29
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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).

Lasso di tempo: Up to 2 weeks post 28 days of treatment
An Adverse Event (AE) was defined as any untoward medical occurrence, signs, symptoms, disease, or laboratory or physiological observations occurring in a participant administered with drug, regardless of a causal relationship with that treatment or usage. This also included all suspected adverse medication reactions, reactions from medication overdose, abuse, withdrawal, sensitivity, toxicity, unrelated illnesses, including worsening a pre-existing condition, injury, or accidents.

Lasso di tempo: Up to 2 weeks post 28 days of treatment
Parameters assessed for laboratory values included hematology, chemistry, urinalysis, and coagulation. The investigator was responsible for reviewing laboratory results for clinically significant changes.
Up to 2 weeks post 28 days of treatment
Number of Participants With Clinically Significant Changes From Baseline in Vital Sign Values
Lasso di tempo: Up to 2 weeks post 28 days of treatment

Number of Participants With Clinically Abnormal 12-Lead Electrocardiogram (ECG) Findings
Lasso di tempo: 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
Lasso di tempo: 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).
Up to 2 weeks post 28 days of treatment
Mean Trough Concentrations of Vadadustat at Day 8, 15, 22 and 29
Lasso di tempo: 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
