Abstract
OBJECTIVE To investigate relationships between baseline factors and treatment-associated efficacy changes in type 2 diabetes. RESEARCH DESIGN AND METHODS Multivariable analyses of treatment response in 1,229 type 2 diabetic patients with hypercholesterolemia who received ezetimibe/simvastatin or atorvastatin in a randomized double-blind 6-week study. RESULTS Increasing age was related to improvements in all lipid assessments. Men had greater triglyceride and non-HDL cholesterol reductions than women, and black/Hispanic patients had less favorable lipid effects than other races/ethnicities. Increasing baseline LDL cholesterol was associated with improvements in most lipids; higher baseline non-HDL cholesterol with improved HDL cholesterol and triglycerides; higher baseline HDL cholesterol with greater non-HDL cholesterol and high-sensitivity C-reactive protein (hs-CRP) reductions; and higher baseline hs-CRP with smaller LDL cholesterol, non-HDL cholesterol, and apolipoprotein B reductions. Patients with high baseline non-HDL cholesterol or triglycerides less frequently attained LDL cholesterol targets. Obesity was inversely related to HDL cholesterol and hs-CRP changes, and higher baseline A1C to smaller apolipoprotein B reductions. Metabolic syndrome was not a significant predictor. CONCLUSIONS Treatment responses in type 2 diabetic patients were related to baseline factors, although treatment effects (ezetimibe/simvastatin being more effective than atorvastatin) remained consistent. The presence of predictive factors should be considered in planning lipid-altering therapy.

Abstract
This analysis of the Ezetimibe Add-on to Statin for Effectiveness (EASE) trial examined the effectiveness and safety of ezetimibe 10 mg added to ongoing statin therapy in patients with diabetes, metabolic syndrome without diabetes, or neither disorder who had low-density lipoprotein cholesterol (LDL-C) levels exceeding National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) goals. After six weeks of treatment, ezetimibe added to statin reduced LDL-C in patients with diabetes by 28%, metabolic syndrome by 24%, or neither by 26%, compared with a 3% reduction for placebo for each group. In each group, more patients receiving ezetimibe plus statin reached LDL-C goal (67-74%) compared with those receiving placebo plus statin (19-22%). Other parameters demonstrating greater improvement with ezetimibe included triglycerides, apolipoprotein (Apo)B/Apo A-I ratio, high-density lipoprotein cholesterol (HDL-C), and C-reactive protein. Ezetimibe plus statin was well tolerated in each group. Ezetimibe added to ongoing statin therapy offers a new treatment option that is consistently effective in improvement of lipid profiles and attainment of LDL-C goals in patients with without diabetes or metabolic syndrome.
