Mixed Hyperlipidemia, Primary Hypercholesterolemia
Conditions
Brief summary
The purpose of this study is to evaluate the effect of SCH 900271 compared to placebo on the reduction of low-density lipoprotein cholesterol (LDL-C) from baseline to 8 weeks of treatment in participants with primary hypercholesterolemia (familial and nonfamilial) or mixed hyperlipidemia. The study will also evaluate the effect of SCH 900271 on non-high density lipoprotein cholesterol (non-HDL-C) and various other lipids and lipoproteins. The safety of SCH 900271 in this participant population will also be evaluated.
Interventions
oral tablets; SCH 900271 - 15 mg taken once daily for 8 weeks
oral tablets; SCH 900271 10 mg taken once daily for 8 weeks
oral tablets; placebo administered once daily during the 5-week single-blind placebo run-in and diet stabilization period and during the 8 week double-blind treatment period.
