Brief Summary:
The primary objective of this study is to evaluate the safety of tolvaptan in pediatric subjects with autosomal recessive polycystic kidney disease (ARPKD)
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Autosomal Recessive Polycystic Kidney (ARPKD) | Drug: Tolvaptan Suspension Drug: Tolvaptan Tablets | Phase 3 |
This study is a multinational, multicenter, open-label, non-randomized trial. The study consist of three periods: Screening Period, Treatment period and Follow-up period.
Tolvaptan has been demonstrated to delay the decline of kidney function in adults with rapidly progressing ADPKD (CKD stages 1 to 4), a closely related indication to ARPKD, as measured by estimated glomerular filtration rate (eGFR) and Total Kidney Volume (TKV).
Participants in this study will be assigned to tolvaptan and followed for 18 months over the course of the study.
The overall trial duration is expected to be approximately 3.5 years.

Experimental: Tolvaptan Suspension
Tolvaptan suspension will be administered orally or via feeding/nasogastric tube at doses of 0.15 mg/kg once daily in the AM, 0.30 mg/kg once daily in the AM, 0.5 mg/kg once daily in the AM, 0.75 mg/kg split dose (0.5 mg/kg AM and 0.25 mg/kg 8 hours later), and 1 mg/kg split dose (0.67 mg/kg AM and 0.33 mg/kg 8 hours later) based on age. Treatment duration is 18 months.

Secondary Outcome Measures :
- Annual rate of change of eGFR (by Schwartz formula) from baseline to post-treatment after 18 months of treatment [ Time Frame: From Enrollment to 18 months ]
- Change from baseline of eGFR (by Schwartz formula) while on treatment at Months 1, 6, 12, and 18 [ Time Frame: 1 month, 6 months, 12 months, and 18 months ]
- The percentage of subjects that will receive renal replacement therapy (RRT) by 18 months. [ Time Frame: From Enrollment to 18 months ]
- The amount of time between enrollment and 18 months that a subject requires renal replacement therapy (RRT). [ Time Frame: From enrollment to 18 months ]
