Dose-finding Study of New Tolvaptan Formulation in Subjects With ADPKD

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)

Outcome Measures
Primary Outcomes (3)
Maximum (Peak) Plasma Concentration of the Drug [Cmax] and Minimum (Trough) Plasma Concentration of the Drug [Cmin] After Tolvaptan Treatment on 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.
Day 7
Time to Maximum (Peak) Plasma Concentration (Tmax) After Tolvaptan Treatment on 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.
Day 7
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.
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.
Day 7
Secondary Outcomes (14)
Number of Participants With Urine Osmolality < 300 mOsm/kg at 23.5 Hours Postdose.
23.5 hours post-dose
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
Change From Baseline in Urine Osmolality at Day 7.
0-4, 4-8, 8-12, 12-16, 16-24 Hours at Day 7

Eligibility Criteria
You may qualify if:
- Subjects (male or female) who are surgically sterile (ie, have undergone hysterectomy) or using contraception or agree to remain abstinent
- Subjects between the ages of 18 and 50, inclusive
- Subjects with a body mass index between 19 to 35 kg/m2 (inclusive)
- Subjects with a diagnosis of ADPKD by modified Ravine criteria
- Subjects must be in good health as determined by medical history, physical examination, ECG, serum/urine biochemistry, hematology, and serology tests
- Subjects with the ability to provide written, informed consent prior to initiation of any trial-related procedures, and ability, in the opinion of the principle investigator, to comply with all requirements of the trial
- Subjects who expect to be able to complete all dosing periods and assessments within 42 (+2) days after dosing on Day 1
You may not qualify if:
- Subjects using diuretics within 14 days prior to check in on Day -1
- Subjects with incontinence, overactive bladder, or urinary retention (eg, benign prostatic hyperplasia)
- Subjects (male or female) with nocturia/urgency (outside of the 2 to 4 times awakening per night expected for ADPKD patients) at screening
- Subjects with liver disease, liver function abnormalities or serology other than that expected for ADPKD with cystic liver disease at baseline
- Subjects with clinically significant abnormality in past medical history, or at the Screening physical examination, that in the investigator's or sponsor's opinion may place the volunteer at risk or interfere with outcome variables including absorption, distribution, metabolism, and excretion of drug.

- Subjects who have taken an investigational drug within 30 days preceding trial entry
- Subjects with any history of significant bleeding or hemorrhagic tendencies
- Subjects with a history of difficulty in donating blood
- Subjects who have donated blood or plasma within 30 days prior to dosing
- Subjects who have consumed alcohol and/or food or beverages containing methylxanthines, grapefruit, grapefruit juice, Seville oranges, or Seville orange juice within 72 hours prior to Day 1 dosing
- Subjects taking CYP3A4 inhibitors, with the exception of amiodarone, taken within 30 days of dosing (eg, amprenavir, atorvastatin, aprepitant, chloramphenicol \[not eye drops\], cimetidine, clarithromycin, clotrimazole \[if used orally\], danazol, delavirdine, diltiazem, erythromycin, fluconazole, fluvoxamine, indinavir, isoniazid, itraconazole, josamycin, ketoconazole, nelfinavir, nefazadone, quinupristin/dalfopristin, ritonavir, saquinavir, troleandomycin, verapamil)
