A Randomized Trial of Modified-Release Versus Immediate-Release Tolvaptan in ADPKD.

ABSTRACT:

Introduction

Tolvaptan, for treatment of autosomal dominant polycystic kidney disease (ADPKD), is provided as immediate-release (IR) tablets administered twice daily in split-dose regimens to suppress urine osmolality to <300 mOsm/kg. A modified-release (MR) formulation was developed for once-daily (QD) dosing to increase compliance and mitigate urinary symptom burden. This phase 2, dose-ranging study (NCT01210560) compared pharmacokinetics, pharmacodynamics, and tolerability of several MR regimens with IR in patients with ADPKD.

Methods

This was a multicenter, parallel-arm, randomized, crossover, double-blind, placebo-controlled trial. Each of 2 study arms had 12 subjects and 3 crossover periods. Dose regimens were administered for 7 days; placebo-masked QD versus split-dos
