issued by the U.S. FDA in 2013 for a New Drug Application for tolvaptan
in the treatment of adults with ADPKD.

About Tolvaptan
Tolvaptan is a selective vasopressin V2-receptor
antagonist. By selectively blocking vasopressin at the V2-receptor,
tolvaptan has been shown to decrease cyst-cell proliferation and fluid
secretion in subjects with ADPKD, ultimately reducing cyst development.ii
In a previous Phase 3 clinical trial, tolvaptan was associated with
reduced kidney growth and slowed decline of kidney function.i
