Brief Summary:
The purpose of this study is to determine whether the medication pravastatin will ameliorate renal and cardiovascular disease over a 3-year period in children and young adults with autosomal dominant polycystic kidney disease (ADPKD).

Condition or disease Intervention/treatment Phase
Polycystic Kidney, Autosomal Dominant Drug: pravastatin Drug: Placebo Phase 3

Detailed Description:

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease, affecting 1 in 400 to 1000 individuals and accounting for 4% of end-stage renal disease in the United States and 8-10% in Europe. The condition is characterized by progressive development of kidney cysts with kidney enlargement and associated loss of kidney function. High blood pressure and cardiovascular disease are common in patients with ADPKD. Although the condition is often thought to affect primarily adults, it is clear that the disease can be present in the fetus and young children.

This study was designed to determine if treatment with the medicine pravastatin can slow the progression of kidney and heart disease when initiated early in life in patients with ADPKD. The Investigators will assess differences between pravastatin and placebo study groups over the three-year study period with respect to: 1) total kidney volume as assessed by magnetic resonance imaging (MRI); 2) left ventricular mass index as assessed by MRI; 3) urinary albumin excretion; and 4) endothelial-dependent vasodilation as assessed by brachial ultrasound. A total of 110 subjects were enrolled in this research study. This study involved pediatric subjects because the Investigators believe that early intervention is critical if they are to decrease the morbidity and mortality associated with this condition. If pravastatin is shown to be effective in ameliorating progression of renal and cardiovascular disease in this study, routine management of people with this condition will be drastically altered.
