Summary
This study assesses whether adding ezetimibe 10 mg/d to ongoing treatment with atorvastatin 10 mg/d is more effective than switching the subject to treatment with rosuvastatin 10 mg/d or doubling the dose of atorvastatin to 20 mg/d is more effective in achieving goal LDL-cholesterol of <2.5 mmol/L. Treatment phase is 6 weeks.

least 80% of daily doses for the 4 weeks preceding Visit 1;

- LDL-C concentration greater than or equal to 2.5 mmol/L to less than or equal to 160
mg/dL (less than or equal to 4.1 mmol/L) based on blood specimens taken at Visit 1,
using the Friedewald calculation as described in the Protocol,Section 8.8. (The lipid
profiles at Visit 3 (baseline) and all subsequent visits were kept "blinded" until
data analysis);

blood specimens taken at Visit 1;

- Documented atherosclerotic disease, CHD, or diabetes mellitus;

- Liver transaminases (ALT, AST) less than 50% above the upper limit of normal, with no
active liver disease, and CPK less than 50% above the upper limit of normal as tested
in blood specimens taken at Visit 1;

- Clinical laboratory tests (CBC, blood chemistries, urinalysis) taken at Visit 1 must
have been within normal limits or clinically acceptable to the Investigator;

- Had been previously prescribed a cholesterol lowering diet and exercise program at
least 4 weeks prior to Visit 1 and had been advised to continue the same diet and
exercise program during the study;

- Reported a stable weight history for at least 4 weeks prior to randomization at Visit
3 (baseline visit);

- Women receiving hormonal therapy, including hormone replacement, any estrogen
antagonist/agonist, or oral contraceptives, must have been maintained on a stable dose
and regimen for at least 8 weeks and willing to continue the same regimen for the
duration of the study;

- Women of childbearing potential (included women who were less than 1 year
postmenopausal and women who became sexually active) must have been using an
acceptable method of birth control (for example, hormonal contraceptive, medically
prescribed IUD, condom in combination with spermicide) or been surgically sterilized
(for example, hysterectomy or tubal ligation).

- Free of any clinically significant diseases other than hyperlipidemia, CHD, or
diabetes mellitus that would interfere with study evaluations;

- Understood and were able to adhere to the dosing and visit schedules, and demonstrated
their willingness to participate in the study and comply with its procedures by
signing a written informed consent.

Exclusion Criteria:

- Consumption greater than 14 alcoholic drinks per week. (A drink is: a can of beer [1/2
pint or 250 ml], glass of wine, or single measure of spirits);

- Any condition or situation which, in the opinion of the Investigator, might have posed
a risk to the subject or interfered with participation in the study;
