OBJECTIVE: To examine whether the improvements in lipid profiles and low-density lipoprotein cholesterol (LDL-C) goal attainment found in the Ezetimibe Add-On to Statin for Effectiveness trial occurred equally in the black, Hispanic, and white patient populations enrolled in the study. PATIENTS AND METHODS: In this double-blind, placebo-controlled study, patients were recruited from 299 community-based practices across the United States (January to August 2003). Patients with, hypercholesterolemia and LDL-C levels exceeding National Cholesterol Education Program Adult Treatment Panel III goals were randomized (2:1) to receive either ezetimibe (10 mg/d) or placebo in addition to their ongoing statin therapy for 6 weeks. RESULTS: A total of 5802 patients were screened at baseline for theEzetimibe Add-On to Statin for Effectiveness study. Of these, 2772 were excluded, and the remaining 3030 eligible patients were randomized. Ezetimibe, compared with placebo, added to statin therapy significantly reduced LDL-C levels from statin-treated baseline by 23.0% (white patients), 23.0% (black patients), and 21.0% (Hispanic patients). This effect was consistent across race and ethnicity groups (P > .50 for treatment-by-race interactions). Ezetimibe added to statin therapy also statistically significantly (P < .001) increased the percentage of patients attaining their LDL-C goal for their National Cholesterol Education Program Adult Treatment Panel III risk category in black (63.0%), Hispanic (64.8%), and white (72.3%) patients compared withplacebo plus statin (32.9% black patients, 19.0% Hispanic patients, and 19.7% white patients). Ezetimibe treatment improved other lipid parameters across groups, including triglyceride, high-density lipoprotein cholesterol, non-high-density ilpoprotein cholesterol, and total cholesterol levels. Finally, the addition of ezetimibe reduced high-sensitivity C-reactive protein levels overall, and no significant interaction of treatment by race occurred (P = .83), Indicating a consistent effect across races. Ezetimibe was generally well tolerated, and no detectable differences occurred in the adverse event profile by race or ethnicity. CONCLUSION:Ezetimibe added to statin therapy is effective and well tolerated for improving the lipid profile and LDL-C goal attainment of patients regardless of race or ethnicity.
