A Study to See if Tolvaptan is Safe in Infants and Children Who at Enrollment Are 28 Days to Less Than 18 Years Old With Autosomal Recessive Polycystic Kidney Disease (ARPKD)
A Phase 3b Multicenter Open-label Trial of the Safety, Tolerability, and Efficacy of Tolvaptan in Infants and Children 28 Days to Less Than 18 Years of Age With Autosomal Recessive Polycystic Kidney Disease (ARPKD)

Intervention / Treatment
Detailed Description
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.

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Male or female subjects between 28 days and less than 18 years of age, with clinical features that are consistent with a diagnosis of ARPKD.
- Ability for parent/legal guardian to provide written, informed consent prior to initiation of any trial-related procedures, and ability, in the opinion of the principal investigator, to comply with all the requirements of the trial. Ability to provide written informed assent from all subjects old enough per local laws to provide assent.
Exclusion Criteria:
- Premature birth (≤ 32 weeks gestational age) for infants 28 days to < 12 weeks of age.
- Anuria or RRT defined as intermittent or continuous hemodialysis, peritoneal dialysis, hemofiltration, hemodiafiltration or history of kidney transplantation.
- Evidence of syndromic conditions associated with renal cysts (other than ARPKD).
- Abnormal liver function tests including ALT and AST, > 1.2 × ULN (upper limit of normal).
- Has splenomegaly or portal hypertension (HTN).
- Parents with renal cystic disease.
- Receiving chronic diuretic that could not be adjusted after tolvaptan initiation.
- Cannot be monitored for fluid balance.
- Has or at risk of having sodium and potassium electrolyte imbalances, as determined by the investigator.
- Has or at risk of having significant hypovolemia as determined by investigator.
- Clinically significant anemia, as determined by investigator.
