evolocumab in advanced chronic kidney disease trial

Conditions: Chronic Kidney Diseases; High Cholesterol

Summary: 110 individuals with stage 4-5 chronic kidney disease (ckd) will be randomized to 1-year of blinded evolocumab or placebo. subjects will undergo evaluation of circulating lipids at baseline and end of study. a substudy including 50 subjects will assess myocardial rest and stress positron emission tomography (pet) at baseline and at 1-year.

the purpose of this study is to evaluate the effect of evolocumab (repatha®)-a food and drug administration (fda)-approved biological drug that has been shown to reduce ldl cholesterol (bad cholesterol) early data show that the beneftis of evolocumab may be increased as kidney function declines. this trial is therefore designed to provide additional evidence regarding the safety and cholesterol-lowering effects of evolocumab compared with placebo, a pill that has no therapeutic effect, in advanced ckd patients.
