Statin Therapy in Patients with Early Stage ADPKD

This study plans to learn if pravastatin is helpful in slowing down the progression of kidney disease in adults with 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 using 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.
