Condition(s) targeted: Hypercholesterolemia; Atherosclerosis

Intervention: Ezetimibe + Simvastatin (Drug); Simvastatin (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Merck Sharp & Dohme Corp.

Summary

The purpose of this study is to evaluate whether coadministration of ezetimibe 10 mg/day with simvastatin 20 mg/day for 12 weeks will result in greater reduction of LDL-C, total cholesterol (TC), triglycerides (TG), non HDL-C, and apolipoprotein B (ApoB), and greater increase in HDL-C, compared with simvastatin 20 mg/day as monotherapy for 12 weeks in African-American subjects with primary hypercholesterolemia. This study is being performed to better define the efficacy of ezetimibe coadministered with simvastatin in this population.

Clinical Details

Official title: A Multicenter, Double-Blind, Randomized Study to Evaluate the Lipid-Altering Efficacy, Safety, and Tolerability of Ezetimibe Coadministered With Simvastatin Versus Simvastatin Monotherapy in African-American Subjects With Primary Hypercholesterolemia

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Percent change in LDL-C from baseline to endpoint.

Secondary outcome: Percent change from baseline to endpoint in TC, TG, HDL-C, non-HDL-C, and ApoB.

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Adult African-American or Black subjects with diagnosis of primary

hypercholesterolemia with plasma LDL-C >=145 mg/dL and <=250 mg/dL, and plasma TG <=350 mg/dL

must be maintained on a stable HRT or raloxifene regimen for at least 6 weeks and throughout the study

- Willingness to give written consent, participate and complete all study-related

procedures, and ability to follow a stable NCEP Step I (or stricter) diet regimen and keep a diet diary when required.

- Clinical laboratory tests (CBC, blood chemistries, and urinalysis) within normal

limits (except as noted below) or clinically acceptable.

- ALT (SGPT) and AST (SGOT) concentrations <=2 times the upper limit of normal (ULN)

and creatine phosphokinase <=2 times the ULN. Exclusion Criteria:
