Study to access whether AMG 145, in people with dyslipidemia, who cannot tolerate an effective dose of a statin, causes any side effects and to confirm that treatment with AMG 145 will lower LDL-cholesterol and increase HDL-cholesterol. To do this, AMG 145 will be compared with ezetimibe which is a cholesterol-lowering medication used to help patients manage cholesterol levels.
