Rationale and Design of a Clinical Trial Investigating Tolvaptan Safety and Efficacy in Autosomal Dominant Polycystic Kidney Disease.

ABSTRACT:

Background

In TEMPO 3:4, the vasopressin V2-receptor antagonist tolvaptan slowed kidney growth and function decline in autosomal dominant polycystic kidney disease (ADPKD) patients with relatively preserved kidney function.

Methods

Prospective, phase 3b, multi-center, randomized-withdrawal, placebo-controlled, double-blind trial of tolvaptan in ADPKD patients with late stage 2 to early stage 4 chronic kidney disease (CKD). The primary endpoint was estimated glomerular filtration rate (eGFR) change from pre-treatment baseline to post-treatment follow-up. Secondary endpoints included annualized eGFR slope, incidence of ADPKD complications, and overall and hepatic safety profiles. Participants were 18-55 year-old ADPKD patients with baseline eGFR ≥25 and ≤65 mL/min/1.73 m2 or 5
