ListOutcomeTime frameDescription
PrimaryPhase A: Change From Baseline in Spot Urine Osmolality (Pre-morning Dose)Baseline, and Week 1 of Phase A
Urine osmolality is a measure of urine concentration, measured by osmometer, which evaluates the freezing point depression of a solution and supplies results as milliosmoles per kilogram of water. Spot urine osmolality was determined for urine samples collected immediately prior to morning dosing for Day 1 (Baseline), and Week 1 for all participants. Sample was taken after the first morning's void and was provided as a mid-stream, clean catch sample. All participants were fasting.
PrimaryPhase A: Change From Baseline in Specific Gravity (Pre-morning Dose)Baseline, and Week 1 of Phase A
Urine specific gravity is a measure of the concentration of solutes in the urine and provides information on the kidney's ability to concentrate urine. Spot urine sample for determination of specific gravity was collected immediately prior to morning dosing for Day 1 (Baseline), and Week 1 for all participants. Sample was taken after the first morning's void and was provided as a mid-stream, clean catch sample. All participants were fasting.
SecondaryPhase A: Percent Change From Phase A Baseline in Height-Adjusted Total Kidney Volume (htTKV) as Measured by Magnetic Resonance Imaging (MRI)Baseline, and Month 12 of Phase AhtTKV is used in participants with autosomal dominant polycystic kidney disease to predict the onset of renal insufficiency.
SecondaryPhase A and B: Mean 24-hour Fluid Balance Prior to Week 1Prior to Week 1 in Phase A and BParticipants were instructed to record all fluid taken and all urine output for the 24-hour period.
SecondaryPhase A: Change From Baseline in Renal Function (Estimated Glomerular Filtration Rate [eGFR] by Schwartz Formula) at Each Clinic Visit in Phase APhase A Baseline, Months 1, 6, and 12
Renal function was assessed by estimated eGFR calculated by the Schwartz formula (eGFR = 0.413 × height \[cm\] /serum creatinine mg/dL), expressed as mean change in eGFR at the specified time points. The units for the data reported are milliliter per minute per 1.73 meter square (mL/min/1.73 m\^2). The baseline was the evaluation done at Week 1 in Phase A for this outcome measure.
SecondaryPhase B: Change From Phase B Baseline in Renal Function (eGFR by Schwartz Formula) at Each Clinic Visit in Phase BPhase B Baseline, Week 1, Months 1, 6, 12, 18, and 24Renal function was assessed by estimated eGFR calculated by the Schwartz formula (eGFR = 0.413 × height \[cm\] /serum creatinine mg/dL), expressed as mean change in eGFR at the specified time points.
SecondaryPhase B: Percent Change From Phase B Baseline in htTKV as Measured by MRI at Month 12 and Month 24Phase B Baseline, Months 12 and 24htTKV is used in participants with autosomal dominant polycystic kidney disease to predict the onset of renal insufficiency.
SecondaryPhase A: 24-hour Urine Volume24 hours post dose after Month 1 on study medication in Phase AUrine volume refers to the quantity of urine produced per unit of time.
SecondaryPhase A: 24-hour Fluid Intake24 hours post dose after Month 1 on study medication in Phase ADaily fluid intake (total water) is defined as the amount of water consumed from foods, plain drinking water, and other beverages.
SecondaryPhase A: 24-hour Fluid Balance24 hours post dose after Month 1 on study medication in Phase AFluid balance is a term used to describe the balance of the input and output of fluids in the body to allow metabolic processes to function correctly.
