Subjects will be randomized to receive either tolvaptan or placebo for 13.5 months. Subjects may be randomly switched back and forth between treatments (to establish tolerance) at different times for defined intervals and are eligible for open enrollment after the end of the study. Men and women aged 18 to 55 years with an estimated glomerular filtration rate (eGFR) between 25 and 65 mL\/min\/1.73 m\u003Csup\u003E2\u003C\/sup\u003E or aged 55 to \u0026lt; 66 years with an eGFR between 25 and 44 mL\/min\/ 1.73 m\u003Csup\u003E2\u003C\/sup\u003E are eligible for the enrollment. Diagnosis of ADPKD is performed with the modified Pei-Ravine criteria including age and number of renal cysts in patients both with and without a family history. Patients with hepatic impairment or liver function abnormalities other than those associated with ADPKD, advanced diabetes, or other significant renal issues (kidney cancer, surgery, or injury) are not eligible to participate.\u003C\/p\u003E\n         \u003Cp id=\u0022p-5\u0022\u003EThe primary purpose is to compare the efficacy of tolvaptan with placebo in reducing the change in eGFR from pretreatment (baseline) to post-treatment follow-up. Secondary objectives are to compare tolvaptan to placebo in reducing the decline of annualized eGFR slope, overall and hepatic safety (monthly monitoring of liver abnormalities), and the incidence of ADPKD complications. It is expected that outcomes will support the previous TEMPO findings that tolvaptan is successful in slowing cyst growth and deterioration of kidney function in ADPKD patients in stages 1 to 3. One caution noted was the higher levels of transaminase (\u0026gt;3 times the upper level of normal) in the TEMPO trial. Close monitoring of transaminase will be performed in the current study.
