Description

Summary

The goal of the study is to compare and evaluate safety and efficacy of tesevatinib 50mg versus placebo in patients with ADPKD.

Official Title

A Double-blind Randomized Parallel Group Study of the Efficacy and Safety of Tesevatinib in Subjects With Autosomal Dominant Polycystic Kidney Disease

Details

Safety and efficacy of 50mg tesevatinib in comparison to placebo in patients with autosomal dominant polycystic kidney disease (ADPKD) will be assessed.

The primary purpose of this study is focused on evaluating the change from baseline in height-adjusted total kidney volume (htTKV) as measured by magnetic resonance imaging (MRI) at Months 12, 18, and 24 in patients with ADPKD treated with tesevatinib or placebo.

If eligible for the study participation, subjects will be randomly assigned to either investigational treatment group or placebo group. Treatment group will receive 50mg tesevatinib once daily for 24 months and control group will receive the placebo once daily for 24 months.

Lead Scientist

  • Meyeon Park
    My research focuses on the early diagnosis of kidney hypoxia, injury, and disease and the influence of cardiovascular disease on kidney disease onset and progression. Clinically, I see patients with all manifestations of hypertension and kidney disease, with a special focus on patients with polycystic kidney disease.
