6. Ability to swallow a tablet [Must also meet Health Authority/Ethics Committee age restrictions on tablet use (if applicable)].
7. Ability to commit to remain fully abstinent (periodic abstinence [eg, calendar, ovulation, symptothermal, post-ovulation methods] or withdrawal are not acceptable methods of contraception) or use two approved methods of birth control during the trial and for 30 days following the last dose of IMP for sexually active females of childbearing potential. Are the trial subjects under 18? yes Number of subjects for this age range: 100 F.1.2 Adults (18-64 years) no F.1.2.1 Number of subjects for this age range 0 F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range 0

2. Liver function tests including AST, ALT = 1.5 × ULN.
3. Nocturnal enuresis.
4. Need for chronic diuretic use.
5. Subjects with advanced diabetes (eg, glycosylated hemoglobin [HgbA1c] > 7.5, and/or glycosuria by dipstick, significant proteinuria, retinopathy), evidence of additional significant renal disease(s) (ie, currently active glomerular nephritides), renal cancer, single kidney, or recent (within 6 months of screening) renal surgery or acute kidney injury.
6. Subjects who have known clinically significant allergic reactions to chemicals with structure similar to tolvaptan (ie benzazepines): benzazepril, conivaptan, fenoldopam mesylate or mirtazapine.
7. Subjects having disorders in thirst recognition or inability to access fluids.
8. Subjects who have bladder dysfunction and/or difficulty voiding.
9. Subjects with critical electrolyte imbalances, as determined by the investigator.
10. Subjects with or at risk of significant hypovolemia, as determined by investigator.
11. Subjects with a history of substance abuse (within the last 6 months).
12. Subjects 12 years of age and older having contraindications to, or interference with MRI assessments (eg, ferro-magnetic prostheses, aneurysm clips, severe claustrophobia).
13. Subjects taking a vasopressin agonist (eg, desmopressin).
14. Subjects with a history of persistent noncompliance with antihypertensive or other important medical therapy.
15. Subjects taking medications or having concomitant illnesses likely to confound endpoint assessments, including taking approved (ie, marketed) therapies for the purpose of affecting PKD cysts such as tolvaptan, vasopressin antagonists, anti-sense RNA therapies, rapamycin, sirolimus, everolimus, or somatostatin analogs (ie, octreotide, sandostatin).
16. Has any medical condition that, in the opinion of the investigator, could interfere with evaluation of the trial objectives or safety of the subjects.
17. Is deemed unsuitable for trial participation in the opinion of the investigator.
18. Subjects who received any investigational agent in a clinical trial within 30 days prior to screening.
19. Subjects who have a known lactose intolerance
20. Subjects who have had cyst reduction surgery within 6 weeks of the screening visit

Primary Outcome(s)
|
Main Objective: To assess the long term safety of treatment with tolvaptan in a pediatric and adolescent ADPKD population.
|
Secondary Objective: To assess the pharmacodynamics (PD), pharmacokinetics (PK), and efficacy of tolvaptan in children and adolescent subjects with ADPKD.
|
Timepoint(s) of evaluation of this end point: After 1 week of daily dosing in Phase A.
|
Primary end point(s): The co-primary endpoints are the change from baseline in spot urine osmolality (premorning dose) and specific gravity (premorning dose) after 1 week of daily dosing in Phase A.
|
Secondary Outcome(s)
|
Timepoint(s) of evaluation of this end point: At the end of Phase A (at 12 months) and at various timepoints during phase B.
|
Secondary end point(s): The key secondary endpoint is the percent change from Phase A baseline in height-adjusted (htTKV) as measured by MRI at 12 months.
Other secondary endpoints:
- 24-hour fluid balance prior to Week 1.
- Change from baseline in renal function (eGFR by Schwartz formula) at each clinic visit (Week 1, Month 1, Month 6, and Month 12 in Phase A).
- Change from baseline in renal function (eGFR by Schwartz formula) at each clinic visit (Week 1, Month 1, Month 6, Month 12, Month18, and Month 24 in Phase B).
- Percent change in htTKV as measured by MRI from Phase B baseline to Phase B Month 12.
- Percent change in htTKV as measured by MRI from Phase B baseline to Phase B Month 24.
- Pharmacodynamic (PD) endpoints of urine volume (including 24-hour fluid volume), fluid intake and fluid balance, sodium, creatinine, and free water clearance during dense PK sampling (after at least 1 Month on IMP).
- Proportions of each Tanner Stage by gender and age compared to normative populations at baseline, 6 months, and 12 months during the placebo-controlled phase (Phase A), and every 6 months during the open-label extension phase (Phase B).
- Description of changes from baseline percentiles for height and weight by gender and age at baseline, 6 months, and 12 months during the placebo-controlled phase (Phase A), and every 6 months during the open-label extension phase (Phase B).
- Safety variables (changes from baseline in creatinine, vital signs, laboratory values including liver function tests [LFTs], rate of aquaretic AEs) in placebo and tolvaptan.
