PrimaryMaximum (Peak) Plasma Concentration of the Drug [Cmax] and Minimum (Trough) Plasma Concentration of the Drug [Cmin] After Tolvaptan Treatment on Day 7.Day 7
Blood samples (6 mL) for determination of tolvaptan PK parameters were collected on Day 1 predose, and on Days 7, 14 and 21 at predose, and 1, 2, 4, 6, 8, 9, 10, 12, 16, and 24 hours postdose. If a sample was not drawn at the designated time, a window of ± 3 minutes for each blood draw was acceptable. Maximum and minimum plasma concentration of the drug was calculated.
PrimaryTime to Maximum (Peak) Plasma Concentration (Tmax) After Tolvaptan Treatment on Day 7.Day 7
Blood samples (6 mL) for determination of tolvaptan PK parameters were collected on Day 1 predose, and on Days 7, 14 and 21 at predose, and 1, 2, 4, 6, 8, 9, 10, 12, 16, and 24 hours postdose. If a sample was not drawn at the designated time, a window of ± 3 minutes for each blood draw was acceptable. Time to maximum plasma concentration was calculated.
Primary
Area Under the Concentration-time Curve During the Dosing Interval at Steady State and Area Under the Concentration-time Curve From Time 0 to 24 Hours Postdose (AUCT & AUC0-24h) After Tolvaptan Treatment on Day 7.
Day 7
Blood samples (6 mL) for determination of tolvaptan PK parameters were collected on Day 1 predose, and on Days 7, 14 and 21 at predose, and 1, 2, 4, 6, 8, 9, 10, 12, 16, and 24 hours postdose. If a sample was not drawn at the designated time, a window of ± 3 minutes for each blood draw was acceptable. Hence, both AUCT and AUC0-24h values were calculated.
SecondaryNumber of Participants With Urine Osmolality < 300 mOsm/kg at 23.5 Hours Postdose.23.5 hours post-dose
For determination of duration of urine osmolality \<300 mOsm/kg, the value was the end time of the last collection interval in which urine osmolality was \<300 mOsm/kg. Day 8 in the table below was defined as Day 8 of Period 1, Day 15 of Period 2, and Day 22 of period 3.
SecondaryChange From Baseline in Urine Osmolality Area Under the Concentration-time Curve From Time 0 to 24 Hours Postdose (AUC0-24h) at Day 7.Day 7
The AUC0-24h for urine osmolality was determined by multiplying the concentration by the collection interval duration for each collection interval and summing all the intervals in the 24-hour period. If the urine volume for an interval is zero, the duration of that interval will be added to the next collection interval. Day 7 was defined as Day 7 of Period 1, Day 14 of Period 2 and Day 21 of Period 3.
SecondaryChange From Baseline in Urine Osmolality at Day 7.0-4, 4-8, 8-12, 12-16, 16-24 Hours at Day 7To determine the tolerability and nighttime urinary suppression of osmolality. The urine osmolality was summarized by collection interval (0 to 4, 4 to 8, 8 to 12, 12 to 16, and 16 to 24 hours)
SecondaryChange From Baseline in Urine Volume at 24 Hours at Day 7.Day 7Urine volume was collected by 0 to 24-hour interval at Day 7. Day 7 was defined as Day 7 of Period 1, Day 14 of Period 2 and Day 21 of Period 3.
SecondaryChange From Baseline in Urine Volume by Interval at Day 7.0-4, 4-8, 8-12, 12-16, 16-24 Hours at Day 7Urine volume collected was by interval (0-4, 4-8, 8-12, 12-16, 16-24 hours). Day 7 was defined as Day 7 of Period 1, Day 14 of Period 2 and Day 21 of Period 3.
SecondaryDuration of Urine Osmolality Less Than 300 mOsm/kg at Baseline and Day 7.Baseline and Day 7
Duration of urine osmolality remains below 300 mOsm/kg was the sum of the durations (nominal times) of all intervals where the urine concentration was \< 300 mOsm/kg. Day 7 was defined as Day 7 of Period 1, Day 14 of Period 2, and Day 21 of Period 3.
SecondaryChange From Baseline in Number of Urine Voids During Awake Periods.Days 1, 2, 3, 4, 5, 6 and 7
Average number of daily urine voids during awake periods for each dose group. Day 1 was defined as Day1 of Period 1, Day 8 of Period 2 adn Day 15 of Period 3; Day 7 was defined as Day 7 of Period 1, Day 14 of Period 2 and Day 21 of Period 3; Same rule applied to Day 2 and Day 6.
SecondaryChange From Baseline in Number of Urine Voids During Sleep Periods.Days 1, 2, 3, 4, 5, 6 and 7
Average number of daily urine voids during sleep periods for each dose group. Day 1 was defined as Day 1 of Period 1, Day 8 of Period 2, Day 15 of Period 3; Day 7 was defined as Day 7 of Period 1, Day 14 of Period 2 and Day 21 of Period 3; Same rule applied to Day 2 to 6.
SecondaryChange From Baseline in Symptom Burden by Autosomal Dominant Polycystic Kidney Disease (ADPKD) Nocturia Quality of Life Questionnaire at Day 6.Day 6
In ADPKD Nocturia Quality of Life Questionnaire, questions 1 to 11 (with possible scores ranging from 0 to 4 and higher scores indicating better quality of life) were pooled to provide a total score (maximum of 44 points). Response scores of Question 12 (with possible scores ranging from 1 to 10, with higher scores indicating more interference (worse quality of life) with everyday life due to urination at night) were pooled separately. Day 6 was defined as Day 6 of Period 1, Day 13 of Period 2 and Day 20 of Period 3.
SecondaryNumber of Participants Experiencing Urinary Urgency Based on Urinary Urgency Questionnaire (Question 1) at Baseline and Day 6.Baseline and Day 6
For the ADPKD Urinary Urgency Questionnaire, Question 1 (currently experiencing urgency?) was assigned 'Yes' or 'No' to measure current urine urgency status. Baseline was defined as last pre-dose evaluation; Day 6 was defined as Day 6 of Period 1, Day 13 of Period 2 and Day 20 of Period 3.
SecondaryChange From Baseline in Urinary Urgency Questionnaire (Questions 2 to 5 and Questions 7 to 14) at Day 6.Day 6
Question 2 to Question 6 were assigned scores of 0 to 4 with higher scores indicating worse cases in experience of urinary urgency. Scores for Question 2 to Question 5 were pooled, with a maximum possible score of 16. Question 6 was excluded from the analysis since it was only asked at screening. Question 7 to Question 14 were also assigned scores of 0 to 4 with higher scores indicating worse cases in impact of urinary urgency on life; scores for these questions were pooled, with a maximum possible score of 32. Baseline was defined as last pre-dose evaluation; Day 6 was defined as Day 6 of Period 1, Day 13 of Period 2 and Day 20 of Period 3.
SecondaryNumber of Participants Experiencing Urinary Frequency Based on Urinary Frequency Questionnaire (Question 1) at Baseline and Day 6.Baseline and Day 6
The ADPKD Urinary Frequency Questionnaire: Question 1 (currently experiencing frequency) was assigned 'Yes' or 'No' to measure current urine frequency status. Baseline was defined as last pre-dose evaluation; Day 6 was defined as Day 6 of Period 1, Day 13 of Period 2 and Day 20 of Period 3.
SecondaryChange From Baseline in Urinary Frequency Questionnaire (Question 2 and Questions 3 to 10) at Day 6.Day 6
Question 2 asked, "During the last 5 days, how much has urinary frequency bothered you?" In order to score the response, the written answers were assigned values from 0 to 4 as follows: 0) Not at all, 1) Somewhat, 2) Moderately, 3) Quite a bit, and 4) Constantly. Question 3 to Question 10 were assigned scores of 0 to 4 with higher scores indicating worse cases in impact of urinary frequency on life; scores for these questions were pooled, with a maximum possible score of 32. Baseline was defined as last pre-dose evaluation; Day 6 was defined as Day 6 of Period 1, Day 13 of Period 2 and Day 20 of Period 3.
SecondaryRanking of Treatment Tolerability.Day 22/Early Termination
Ranking of treatment tolerability was evaluated based on a questionnaire. At Day 22, participants were asked the following questions and their responses recorded on the eCRF: "Which treatment period did you find most tolerable?" and "Which treatment period did you find the least tolerable?".
