Study Description

Brief Summary

To establish pharmacokinetics (PK), pharmacodynamics (PD), and adverse event (AE) profile of tolvaptan administered as the modified-release (MR) formulation in ADPKD subjects. The goals of this trial are two-fold:

  1. To directly compare the immediate release (IR) and MR formulations

  2. To determine the dose range and dose regimen for MR (dose finding)

Phase 2

Detailed Description

Group 1 will have 12 subjects enrolled in a 3-period, randomized, crossover to compare multiple doses of a 90-30 mg split-dose of the tolvaptan IR formulation, a 120 mg once daily (QD) dose of the tolvaptan MR formulation, and, in an incomplete block randomization, multiple doses of either 20 mg QD, 60 mg QD, or 20 mg twice daily (BID) tolvaptan MR formulation. All dose regimens will be administered for 7 days. Placebo doses will be administered in order to mask QD vs BID treatments.

Group 2 will have 12 subjects enrolled in a 3-period, randomized, crossover to compare multiple oral doses of the tolvaptan MR formulation administered for 7 days as 20 mg QD, 60 mg QD, and 20 mg BID. Placebo capsules will be administered in order to mask QD vs BID treatments.

Subjects will have in-clinic assessments on 12 days to obtain 24-hour PK and PD data. Subjects will visit the clinic from the afternoon of Day -1 through the morning of Day 1. They will return at the end of each dosing period for a similar inpatient period (ie, from the afternoon of Day 6 through the morning of Day 8, from the afternoon of Day 13 through the morning of Day 15, from the afternoon of Day 20 through the morning of Day 22). Except for the first dose of each period and the doses taken in the clinic on the last day of each regimen and the afternoon of Days 6, 13 and 20, all other doses will be taken by the subject as an outpatient.

    Primary Outcome Measures

    1. Maximum (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.

    2. Time 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.

    3. 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.

    Secondary Outcome Measures

    1. Number 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.

    2. Change 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.

    3. Change From Baseline in Urine Osmolality at Day 7. [0-4, 4-8, 8-12, 12-16, 16-24 Hours at Day 7]

      To 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)

    4. Change From Baseline in Urine Volume at 24 Hours at Day 7. [Day 7]

      Urine 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.

    5. Change From Baseline in Urine Volume by Interval at Day 7. [0-4, 4-8, 8-12, 12-16, 16-24 Hours at Day 7]

      Urine 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.

    6. Duration 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.

    7. Change 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.

    8. Change 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.

    9. Change 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.

    10. Number 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.

    11. Change 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.

    12. Number 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.

    13. Change 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.

    14. Ranking 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?".

    9. Secondary Outcome
    Title Duration of Urine Osmolality Less Than 300 mOsm/kg at Baseline and Day 7.
    Description 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.
    Time Frame Baseline and Day 7

    Outcome Measure Data

    Analysis Population Description
    The duration that urine osmolality remained < 300 mOsm/kg was not calculated. Instead was calculated as the sum where urine osmolality was < 300 mOsm/kg in the 24-hour postdose period. The change was made because low doses of the MR formulation frequently do not produce suppression of urine osmolality in the 0- to 4-hour period.

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.
