title: Comparative effects on lipid levels of combination therapy with a statin and extended-release niacin or ezetimibe versus a statin alone (the COMPELL study).
abstract: International guidelines recommend lower target cholesterol levels and treatment of low high-density lipoprotein cholesterol (HDL-C) and elevated triglycerides for patients at moderately high to high coronary heart disease (CHD) risk. Combination therapy is often required to achieve multiple lipid treatment goals, and > or =50% reduction in low-density lipoprotein cholesterol (LDL-C) is needed in some patients to achieve aggressive LDL-C targets. In this context, we evaluated comparative effects on lipid levels of combination therapy at low to moderate doses with a statin plus extended-release niacin (niacin ER), a statin plus ezetimibe, and a highly potent statin alone. This was an open-label, multicenter, 12-week study in 292 patients (50% women) who qualified for drug therapy based on number of CHD risk factors. Patients were randomized to four parallel arms, titrated from low to moderate or high doses: atorvastatin/niacin ER, rosuvastatin/niacin ER, simvastatin/ezetimibe, or rosuvastatin alone. Baseline mean values were, for LDL-C 197 mg/dL (5.1 mmol/L), HDL-C 49 mg/dL (1.3 mmol/L), triglycerides 168 mg/dL (1.9 mmol/L). There were no significant differences among treatment groups in the change from baseline in LDL-C at pre-specified timepoints during treatment. All groups lowered LDL-C by approximately 50% or more (range -49 to -57%), achieving mean levels of 82-98 mg/dL (2.1-2.5 mmol/L). Changes in non-HDL-C (range -46 to -55%) mirrored those for LDL-C and did not differ among treatment groups. Statin/niacin ER combination regimens also increased HDL-C and large HDL (HDL2) and lowered triglycerides and lipoprotein (a) significantly more than other regimens. No drug-related myopathy or hepatotoxicity was observed. In this study, low to moderate dose combination therapy with a statin and niacin ER provided broad control of lipids and lipoproteins independently associated with CHD.
