Efficacy of Lapaquistat Acetate in Subjects With Hypercholesterolemia
23 maj 2012 uppdaterad av: Takeda
A Double-blind, Randomized Study to Evaluate the Efficacy and Safety of Lapaquistat Acetate 100 mg in the Morning vs Lapaquistat Acetate 100 mg in the Evening vs Lapaquistat Acetate 50 mg Twice Daily vs Placebo in Subjects With Hypercholesterolemia
The purpose of this study is to determine the role of time of dosing on the lipid-lowering effects of lapaquistat acetate, once daily (QD) or twice daily (BID), in subjects with hypercholesterolemia.

Detaljerad beskrivning
Dyslipidemias are a group of metabolic disorders produced by raised concentrations of lipoproteins, especially low-density lipoprotein cholesterol the lipoprotein that transports endogenous cholesterol from the liver to the peripheral tissues. Increased cholesterol and triglyceride levels lead to an increased risk of arteriosclerosis, the underlying cause of heart attack, strokes and peripheral vascular disease. Despite changes in lifestyle and the availability of potent lipid-lowering agents, cardiovascular disease continues to be the major cause of death in Western Europe and North America.
Lapaquistat acetate is being developed by Takeda for the treatment of hypercholesterolemia.
