Information source: Schering-Plough
Information obtained from ClinicalTrials.gov on June 20, 2008
Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Hypercholesterolemia; Atherosclerosis; Coronary Artery Disease

Intervention: Rosuvastatin (Drug); Ezetimibe + Atorvastatin (Drug); Double Atorvastatin (Drug)

Phase: Phase 4

Status: Terminated

Sponsored by: Schering-Plough

Official(s) and/or principal investigator(s):
Bernhard Paulweber, MD, Principal Investigator, Affiliation: General Hospital, Salzburg

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.

Clinical Details

Official title: An Open-Label, Randomized, Parallel-Group, Multicenter Study to Compare the Efficacy and Safety of "Switching" to Rosuvastatin 10 mg Daily Versus Atorvastatin 10 mg Daily With Ezetimibe 10 mg Daily Versus Doubling the Dose of Atorvastatin to 20 mg Daily in Subjects With Hypercholesterolemia and Atherosclerotic or Coronary Vascular Disease or Diabetes Mellitus Who Have Not Achieved Study Target LDL-C Goal While Dosing With Atorvastatin 10 mg Daily

Study design: Treatment, Randomized, Open Label, Active Control, Parallel Assignment, Safety/Efficacy Study

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

Secondary outcome:

Percent changes from baseline to the end of treatment in the concentrations of total cholesterol (TC), non-HDL-C, apo B, triglycerides (TG), HDL-C, LDL-C/HDL-C ratio, and TC/HDL-C ratio.

Adverse events, laboratory test results, vital signs.

Eligibility

Minimum age: 18 Years. Maximum age: 75 Years. Gender(s): Both.

Criteria:

Inclusion Criteria:

- 18 years to 75 years of age;

- Stabilized on atorvastatin 10 mg daily and by subject reported history had taken at

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);

- Triglyceride concentration of less than 350 mg/dL (less than 3. 99 mmol/L) based on

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;

- Body mass index (BMI) >= 35 Kg/m^2 at Visit 2 (Screening);

- Women who were pregnant or nursing;

- Failure to observe the designated washout periods for any of the prohibited

medications
