Ramy czasowe
Mean Change From Baseline in Hemoglobin (Hgb) on Day 29
Ramy czasowe: 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.

Ramy czasowe: 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

Ramy czasowe: 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
