|Brief Title ICMJE||Addition of Ezetimibe (Ezetrol®) to Ongoing Therapy With Rosuvastatin (Crestor®) in HIV Positive Patients Not Reaching Cholesterol Targets|
|Official Title ICMJE||A Prospective, Randomized Study to Determine the Effect of Ezetimibe in Addition to Rosuvastatin on Lipids in Participants With the Hypercholesterolemia Associated With HIV Antiretroviral Therapy|
This study involves comparing the effectiveness of treatments in HIV positive patients who may be predisposed to heart attack or stroke. The investigators will evaluate the effectiveness of two drugs, often prescribed by doctors to these patients, at lowering cholesterol and thereby making the patient less them less vulnerable to suffering a heart attack or stroke. The investigators believe that the addition of a second drug, from a different class of cholesterol lowering medications, will improve the outcome of the patients by lowering cholesterol.
This study seeks to determine whether HIV positive patients who have suboptimal lipids and/or are not reaching specified lipid targets will benefit from the addition of a second lipid lowering drug (ezetimibe) to existing lipid lowering therapy with a statin (specifically rosuvastatin) versus increasing the dose of the ongoing statin in terms of improvements in serum lipid parameters namely total cholesterol, LDL, HDL, triglycerides and apolipoprotein B100 (apoB), apolipoprotein A1 (apoA1), apoB/apoA1 ratio.
The target population will be HIV+ patients with hypercholesterolemia due to highly active antiretroviral therapy, the study will have a randomized, parallel design. Sample size will be 50 patients already taking 10 mg of rosuvastatin who are not reaching lipid targets to receive either an increased dose of rosuvastatin (20mg) or to receive 10mg ezetimibe in addition to their ongoing rosuvastatin therapy. There will be 25 patients randomized to each group.
At baseline serum samples will be obtained and tested for serum triglycerides, total cholesterol, HDL, total cholesterol:HDL ratio, apoB, apoA1, apoB/apoA1 ratio, liver transaminases (AST and ALT), CK, thyroid stimulating hormone, creatinine and fasting blood glucose.
After 12 weeks of therapy serum samples will once again be obtained and tested for serum triglycerides, total cholesterol, HDL, total cholesterol:HDL ratio, apolipoprotein B100, liver transaminases (AST and ALT), CK, thyroid stimulating hormone, creatinine and fasting blood glucose.
The primary hypothesis is that the combination of rosuvastatin and ezetimibe will lower serum apolipoprotein B100/apolipoprotein A1 ratio more so than an increased dose of rosuvastatin alone, in participants with mixed dyslipidemia associated with HIV therapy.
Secondarily we believe the combination of rosuvastatin and ezetimibe will lower the concentrations of serum cholesterol, LDL-cholesterol, triglycerides, apolipoprotein B100 and C-reactive protein more so than an increased dose of rosuvastatin alone, and that there will be no increase in side effects when administered to participants with mixed dyslipidemia associated with HIV therapy.
