Daprodustat Hepatic Impairment Study

Daprodustat (GSK1278863), is a small molecule currently in development for the treatment of anemia of chronic kidney disease (CKD). Results of the earlier studies shows that liver is involved in the clearance of Daprodustat and hence, hepatic impairment can affect Daprodustat levels in the body. This single dose study will assess the effect of liver impairment on the pharmacokinetics (PK) and pharmacodynamics (PD) of daprodustat. The study will be conducted in two parts, Part 1 will include subjects with moderate hepatic impairment and matched healthy control subjects whereas Part 2 will include subjects will either mild or severe hepatic impairment and matched healthy control subjects. Approximately 8 subjects will be included in each of the group and all subjects will receive 6 milligram (mg) of daprodustat as a single oral dose in the fasted state. Total duration of participation in the study for a subject will be up to 7 weeks.

    Time frame: Baseline (Screening) and up to Day 16

    Blood samples were collected for analysis of following parameters. PCI ranges were <30g/L (albumin), <2 or >2.75 mmol/L (calcium), <3 or >9mmol/L (glucose), >=2 times ULN U/L (ALT), >=2 times ULN U/L (alkaline phosphatase), >=2 times ULN U/L (AST), >=1.5 times ULN µmol/L (bilirubin), <3 or >5.5 mmol/L (potassium), and <130 or >150 mmol/L (sodium). Participants were counted in worst case category that their value changes to (low, within range or no change or high), unless there is no change in their category. Participants whose laboratory value category was unchanged (e.g., High to High), or whose value became within range, were recorded in To within Range or No Change category. Participants were counted twice if the participant has values that changed To Low and To High, so the percentages may not add to 100%. Baseline is defined as latest non-missing scheduled pre-dose assessment.

  13. Part 1: Number of Participants With Abnormal Urinalysis Findings

    Time frame: Up to Day 16

    Urine samples were collected at indicated time points for the analysis of urine parameters including specific gravity and Potential of hydrogen (pH) of urine, presence of glucose, protein, blood, ketones, bilirubin, urobilinogen, nitrite, and leukocyte esterase in urine.

  14. Part 2: Number of Participants With Abnormal Urinalysis Findings

    Time frame: Up to Day 16

    Urine samples were collected at indicated time points for the analysis of urine parameters including specific gravity and Potential of hydrogen (pH) of urine, presence of glucose, protein, blood, ketones, bilirubin, urobilinogen, nitrite, and leukocyte esterase in urine.
