  • Ages 18 to 80 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • 80-120 patients will be recruited in this study. All patients must meet the following criteria and follow an NCEP or similar cholesterol-lowering dietary regimen throughout the study:
  • Men or women ≧18 and ≦80 years of age (Female patients receiving hormone therapy [including hormone replacement therapy, and estrogen antagonist/agonist, or oral contraceptives] and maintained on a stable dose and regimen for at least 8 weeks prior to visit 1 must be willing to continue the same regimen throughout the study. Females of childbearing potential must be using a medically acceptable method of birth control).
  • Willing to follow an NCEP Therapeutic Lifestyle Changes (TLC) or similar cholesterol-lowering diet for the duration of the study.
  • Patients with hypercholesterolemia who cannot achieve the optimal therapeutic goal with previous statin treatment (simvastatin 20 mg, atorvastatin 10 mg or pravastatin 20 mg alone for at least 12 weeks) will be enrolled into study. The treatment goal in primary prevention is LDL-C <160 mg/dL or LDL-C <130 mg/dL patient with ≧ 2 risk factors (risk factors: hypertension, male ≧ 45 years old, family of premature coronary artery disease [CAD], female ≧ 55 years old or menopause without hormone replace therapy, smoking); LDL-C ≤ 100 mg/dL in CAD patients (documented by coronary angiogram, positive treadmill test or thallium scan), or diabetes mellitus (DM) patients (Ante Cibum [AC][fasting plasma glucose] >126 mg/dL, Post Cibum [PC] [oral glucose tolerance test] > 200 mg/dL, World Health Organization criteria), ischemic stroke (neurological dysfunction with documented diagnosis with computed tomography [CT] or magnetic resonance imaging [MRI]), peripheral artery disease.
  • Triglyceride (TG) concentrations ≦ 400 mg/dL.
  • Liver transaminases (alanine aminotransferase [ALT] and aspartate aminotransferase [AST]) ≦ 2 x upper limit of normal (ULN) with no active liver disease and creatine kinase (CK) ≦ 2 x ULN at screen visit.

Who cannot join

  • The following conditions preclude patients from entry into this study:
  • Women who are pregnant or lactating.
  • History of mental instability, drug/alcohol abuse within the past 5 years, or major psychiatric illness not adequately controlled and stable on pharmacotherapy
  • Patients who have been treated with any other investigational drug within 3 months of visit 1.

  • Lipid-lowering agents including fish oils, Cholestin, bile-acid sequestrants, and niacin (<200 mg/day) taken within 6 weeks and fibrates taken within 8 weeks prior to enrollment.
  • Oral corticosteroids unless used as replacement therapy for pituitary/adrenal disease and treated with a stable regimen for at least 6 weeks prior to enrollment.
  • Treatment with psylium, other fiber-based laxatives, and/or over-the-counter (OTC) therapies known to affect serum lipid levels, phytosterol margarines, unless treated with a stable regimen for at least 6 weeks prior to enrollment, and patient agrees to remain on constant regimen for the duration of the study.
  • Patient is consuming > 250 ml of grapefruit juice per day.

About this study

Official title: A Multicenter, Randomized, Open-labeled, Parallel Group Comparison Study to Evaluate the Efficacy, Safety and Tolerability of Ezetimibe Added to Ongoing Statin Therapy Versus Doubling the Dose of Ongoing Statin in the Treatment of Hypercholesterolemia.

This is a randomized, open label, parallel group comparison study. Following a 1-week screening period, patients will be randomized to 1 of 2 treatment groups: ezetimibe added to ongoing statin treatment (ezetimibe plus simvastatin, atorvastatin or pravastatin at doses of 10/20, 10/10 or 10/20 mg), or doubling the dose of ongoing statin (simvastatin 40 mg, atorvastatin 20 mg, or pravastatin 40 mg). Study drug will be administered once daily in the evening for 8 weeks. Patients will be instructed to follow a National Cholesterol Education Program (NCEP) or similar cholesterol-lowering dietary regimen throughout the study.

Being tested
Ezetimibe + Statin (simvastatin, atorvastatin, or pravastatin), Double Statin (simvastatin, atorvastatin, or pravastatin)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ezetimibe + Statin (simvastatin, atorvastatin, or pravastatin) and Double Statin (simvastatin, atorvastatin, or pravastatin) in people with Hypercholesterolemia, run by Organon and Co.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Jun 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage Change in Low Density Lipoprotein-Cholesterol (LDL-C) From Baseline at Study Endpoint, After 8 Weeks of Treatment (time frame: Assessed at the end of 8 weeks of treatment (from baseline to endpoint)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00652327, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Feb 2022.
