Efficacy and Safety of HS-25 or in Combination With Atorvastatin in Chinese Adults With Primary Hypercholesterolemia

Study Overview
=================
Brief Summary
-----------------
To determine the efficacy of the HS-25 (10mg or 20mg) or in combination with Atorvastatin (10mg)in reducing low density lipoprotein-cholesterol (LDL-C) levels after a 12-week period of treatment in adults with primary hypercholesterolemia; To determine the safety of HS-25 (10mg or 20mg) or in combination with Atorvastatin (10mg)in subjects with LDL-C after a 40-week period of treament.

Detailed Description
-----------------
This is a 12-week, randomized, double-blind, double dummy, placebo-controlled study designed to assess the effects of the cholesterol absorption inhibitor HS-25 (10mg or 20mg) or in combination with Atorvastatin (10mg) on LDL-C levels in adults who have untreated LDL-C levels ranging from 3.36-4.88mmol/L(130-189 mg/dL)and fasting triglyceride levels < 350 mg/dL. Eligibility is restricted to 18-70 years old men or women who are using a highly effective birth control method or are not of childbearing potential;subjects with not treated by statins in six months before signature of the informed consent.Subjects with diabetes, a history of myocardial infarction or other clinical evidence of atherosclerotic vascular disease or treated are not eligible for participation in the study.
