ListOutcomeTime frameDescription
PrimaryMean Change From Baseline in Measured Glomerular Filtration Rate (mGFR) After 3 Weeks of Tolvaptan Treatment and at 3 Weeks Post Treatment.After 3 weeks of treatment and 3 weeks post treatment
Renal function measurements were performed using the constant infusion method with 125I-iothalamate and 131I-hippuran. A priming solution containing 20 mL infusion solution (0.04 MBq of 125I-iothalamate and 0.03 MBq of 131I-hippuran) was given at 08:00 hours, followed by a constant infusion of 6 to 12 mL/h, with the lowest infusion rates in subjects with impaired renal function, based on previously known serum creatinine concentrations. Plasma concentrations of both tracers were allowed to stabilize during a 1.5-hour equilibration, which was followed by two 2-hour periods (09:30 to 11:30 hours and 11:30 to 13:30 hours) for simultaneous clearances of 125I-iothalamate and 131I-hippuran. Blood was drawn at 1, 2, 3, 4, and 5 hours post consumption of water/tolvaptan (08:30 hours). The mGFR was corrected for voiding errors.
PrimaryMean Change From Baseline in Effective Renal Plasma Flow (ERPF) After 3 Weeks of Tolvaptan Treatment and at 3 Weeks Post Treatment.After 3 weeks of treatment and 3 weeks post treatment
Renal function measurements were performed using the constant infusion method with 125I-iothalamate and 131I-hippuran.

Blood was drawn at 1, 2, 3, 4, and 5 hours post consumption of water/tolvaptan (08:30 hours).
PrimaryMean Change From Baseline in Filtration Fraction (GFR/ERFP) After 3 Weeks of Tolvaptan Treatment and at 3 Weeks Post Treatment.After 3 weeks of treatment and 3 weeks post treatment
Renal function measurements were performed using the constant infusion method with 125I-iothalamate and 131I-hippuran. A priming solution containing 20 mL infusion solution (0.04 MBq of 125I-iothalamate and 0.03 MBq of 131I-hippuran) was given at 08:00 hours, followed by a constant infusion of 6 to 12 mL/h, with the lowest infusion rates in subjects with impaired renal function, based on previously known serum creatinine concentrations.

Blood was drawn at 1, 2, 3, 4, and 5 hours post consumption of water/tolvaptan (08:30 hours).
SecondaryMean Change From Baseline in Free Water Clearance After 3 Weeks of Tolvaptan Treatment and at 3 Weeks Post TreatmentAfter 3 weeks of treatment and 3 weeks post treatment
Renal function measurements were performed using the constant infusion method with 125I-iothalamate and 131I-hippuran. A priming solution containing 20 mL infusion solution (0.04 MBq of 125I-iothalamate and 0.03 MBq of 131I-hippuran) was given at 08:00 hours, followed by a constant infusion of 6 to 12 mL/h, with the lowest infusion rates in subjects with impaired renal function, based on previously known serum creatinine concentrations.

Blood was drawn at 1, 2, 3, 4, and 5 hours post consumption of water/tolvaptan (08:30 hours).

Blood sampling for determination of tolvaptan concentrations took place at the Baseline, Final Treatment, and the Post Treatment or Early Termination visits. At the Final Treatment visit (Day 21 \[+/- 1 day)\]), blood samples were collected prior to the start of infusion of study treatment and at 1, 2, 3, 4, and 5 hours postdose. At the Baseline (Day 0), and Post Treatment visit (3 weeks \[+/-3 days\] after last dose), a blood sample was collected prior to the start of infusion of study treatment.
SecondaryTime to Peak Plasma Concentration (Tmax) After 3 Weeks of Tolvaptan Treatment.Day 0: 0 hour, Day 21: (0, 1, 2, 3, 4 and 5 hours postdose), 3 Weeks after last dose: 0 hour
Blood sampling for determination of tolvaptan concentrations took place at the Baseline, Final Treatment, and the Post Treatment or Early Termination visits. At the Final Treatment visit (Day 21 \[+/- 1 day)\]), blood samples were collected prior to the start of infusion of study treatment and at 1, 2, 3, 4, and 5 hours postdose. At the Baseline (Day 0), and Post Treatment visit (3 weeks \[+/-3 days\] after last dose), a blood sample was collected prior to the start of infusion of study treatment.
SecondaryArea Under the Concentration-time Curve From 0 to 5 Hours (AUC0-5) After 3 Weeks of Tolvaptan Treatment.Day 0: 0 hour, Day 21: (0, 1, 2, 3, 4 and 5 hours postdose), 3 Weeks after last dose: 0 hour

At the Final Treatment visit (Day 21 \[+/- 1 day)\]), blood samples were collected prior to the start of infusion of study treatment and at 1, 2, 3, 4, and 5 hours postdose. At the Baseline (Day 0), and Post Treatment visit (3 weeks \[+/-3 days\] after last dose), a blood sample was collected prior to the start of infusion of study treatment.
SecondaryPercentage Change From Baseline in Total Kidney Volume (TKV) After 3 Weeks of Tolvaptan Treatment and at 3 Weeks Post Treatment.After 3 weeks of treatment and 3 weeks post treatmentTKV was measured using magnetic resonance imaging.
SecondaryMean Change From Baseline in 24 Hour Urine Volume After 3 Weeks Tolvaptan Treatment and at 3 Weeks Post Treatment.24 hours
A 24-hour split urine sample (approximate times: 0700 to 1700 hours, 1700 hours to bedtime, and bedtime to 0700 hours) was collected beginning the day before the Baseline, Final Treatment, and Post Treatment visits and ending at admission to the renal function ward. Individual voids in a collection interval were pooled and the total volume determined.
SecondaryMean Change From Baseline in 2 Hour Urine Volume After 3 Weeks Tolvaptan Treatment and at 3 Weeks Post Treatment.2 hours
The volume of urine from each 2-hour urine collection in the renal function tests at Baseline, Final Treatment, and Post Treatment was recorded. Individual voids in a collection interval were pooled before determination of total volume.
