Clinical Trial Summary

This study plans to learn if pravastatin is helpful in slowing down the progression of kidney disease in adults with autosomal dominant polycystic kidney disease (ADPKD). Pravastatin has been approved by the Food and Drug Administration (FDA) for adults for treatment of hyperlipidemia (high cholesterol levels). The investigators are using pravastatin in this study as an investigational drug for treatment of ADPKD.

Description:

This is a randomized, double-blind, placebo-controlled trial designed to assess the efficacy and benefits of pravastatin therapy in adults with ADPKD by evaluating 1) kidney volume as measured by kidney magnetic resonance imaging (MRI); 2) renal blood flow as measured by kidney magnetic resonance angiography (MRA); 3) kidney function as assessed by Glofil-125; 4) plasma and urine protein markers that will allow a better understanding of how pravastatin works in ADPKD; and 5) blood vessel stiffness as measured by carotid-femoral pulse wave velocity. These parameters will be measured at baseline and after 2 years of pravastatin or placebo treatment in 150 patients with ADPKD.
