Detailed Description
Therapeutic interventions aimed at counterbalancing the effect of vasopressin and/or normalizing intracellular levels of cAMP may be effective in delaying disease progression in autosomal dominant polycystic kidney disease (ADPKD).
The primary objectives of this study in subjects with ADPKD are:
- To characterize the safety and tolerability of lixivaptan following multiple doses in ADPKD subjects with relatively preserved kidney function (chronic kidney disease CKD1 and CKD2) and moderately impaired renal function (CKD3).
The secondary objectives of this study are:
- To characterize the PK profile of lixivaptan and its major metabolites following multiple doses of lixivaptan in ADPKD subjects with relatively preserved kidney function (CKD1 and CKD2) and moderately impaired renal function (CKD3).
- To characterize the pharmacodynamic effect of lixivaptan on urine output, urine osmolality, total kidney volume, serum vasopressin, and serum creatinine following multiple doses of lixivaptan in ADPKD subjects with relatively preserved kidney function (CKD1 and CKD2) and moderately impaired renal function (CKD3).

Time Frame |
---|---|---|
Volume of Distribution Over 24 Hours After Extravascular Dosing (VZ/F24H) of Lixivaptan in ADPKD Patients
Time Frame: Day 7 (am)
|
The pharmacokinetic parameter VZ/F24H for lixivaptan, calculated as CL/F24H divided by Day 7 PM λZ, will be summarized by cohort.
VZ/F24H was not specified in the statistical analysis plan and was calculated for the combined 24-hour period including AM and PM dosing intervals on Day 7.
This parameter replaces VZ/F initially planned for the Day 7 AM dose.
