Healthy, Renal Insufficiency
Conditions
Brief summary
This multiple ascending dose (MAD) study in healthy subjects and subjects with mild to moderate renal impairment will evaluate the safety, tolerability and pharmacokinetics of KBP-5074. Safety/tolerability data and Pharmacokinetics (PK)/Pharmacodynamics (PD) (plasma aldosterone, serum potassium, UACR and Blood Pressure) relationships will be explored to support the selection of dosing regimens of KBP-5074 that are suitable for the Phase II/III study.
Detailed description
This study consists of two parts: Part 1 is an open-label, multiple ascending dose (MAD) study to evaluate the safety, tolerability and pharmacokinetics of KBP-5074 in healthy subjects. The safety and tolerability will be assessed at each dose level before progressing to the next higher dose. Part 2 is an open label, randomized, parallel study to assess the safety and tolerability, the effect of renal dysfunction on the pharmacokinetics of KBP-5074, as well as the PK/PD relationship in subjects with mild to moderate renal impairment.
