Detailed Description

Tolvaptan has been demonstrated to delay the decline of kidney function in adults with rapidly progressing ADPKD (CKD stages 1 to 3), a closely related indication to ARPKD, as measured by estimated glomerular filtration rate (eGFR) and Total Kidney Volume (TKV). The trial will be the first trial of tolvaptan in a pediatric ARPKD population. Participants in this study will be assigned to tolvaptan for 24 months and closely monitored over the course of the study.
