What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants That Experienced One or More Components of the Composite Clinical Endpoint of MCE (Major Cardiovascular Events)
Composite endpoint of MCE consists of cardiovascular death, AVR (aortic valve replacement) surgery, CHF(congestive heart failure) as a result of progression of aortic stenosis, nonfatal MI (myocardial infarction), CABG (coronary artery bypass) surgery, PCI (percutaneous coronary intervention), hospitalized unstable angina, and nonhemorrhagic stroke
Measured: Entire follow-up (median = 4.35 years)
Secondary outcomes (3)
Number of Participants That Experienced One or More Components of the Composite Clinical Endpoint of AVE (Aortic Valve Events)
Composite endpoint of AVE (aortic valve events) consists of AVR surgery, CHF (as a result of progression of AS), or cardiovascular death
Measured: Entire follow-up (median = 4.35 years)
Number of Participants That Experienced One or More Components of the Composite Clinical Endpoint of ICE (Ischemic Cardiovascular Events)
Composite endpoint of ICE (ischemic cardiovascular events) consists of cardiovascular death, nonfatal MI, CABG, PCI, hospitalized unstable angina, and nonhemorrhagic stroke
Measured: Entire follow-up (median = 4.35 years)
Change From Baseline in Peak Transaortic Jet Velocity
Mean change from baseline in peak transaortic jet velocity
Measured: Baseline to End of follow-up (median = 4.35 years) or pre-aortic valve replacement

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing ezetimibe (+) simvastatin in people with Aortic Stenosis, 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 1 inclusion and 1 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 16 May 2024. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 27 May 2009). 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?
Number of Participants That Experienced One or More Components of the Composite Clinical Endpoint of MCE (Major Cardiovascular Events) (time frame: Entire follow-up (median = 4.35 years)). 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 NCT00092677, which also lists 35 linked publications.
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 16 May 2024.
