Clinical Trial Summary

The primary objective of this study is to evaluate the effect of tolvaptan on the need for renal replacement therapy in pediatric subjects with autosomal recessive polycystic kidney disease (ARPKD)


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.
