What is being measured
The primary outcome is the main question the study is designed to answer.
Nominal change in intermediate SVG lesion percent atheroma volume (PAV) from baseline to 78 weeks post randomization, as assessed by intravascular ultrasonography (IVUS).
To evaluate the effect of alirocumab on the change in burden of saphenous vein graft (SVG) atherosclerosis as measured by percent atheroma volume (PAV) in patients with intermediate SVG lesions who are undergoing clinically-indicated coronary angiography and are receiving optimal statin therapy.
Measured: 78 weeks
Secondary outcomes (3)
Nominal change in TAV and normalized TAV of an intermediate SVG lesion from baseline to 78 weeks
evaluate the effect of alirocumab on the change in total and normalized total atheroma volume (TAV) of an intermediate SVG lesion
Measured: 78 weeks
Angiographic failure of target SVG lesion from baseline to 78 weeks.
To evaluate the effect of alirocumab on the incidence of angiographic failure of an intermediate target SVG lesion.
Measured: 78 weeks
Incidence of target SVG failure and major adverse cardiac events.
To evaluate the effect of alirocumab on the incidence of target SVG failure (defined as the composite of death, myocardial infarction, and target lesion revascularization) and the incidence of major adverse cardiac events (MACE, defined as the composite of death, acute coronary syndrome, or coronary revascularization) during follow-up.
Measured: Randomization to 80 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Alirocumab 150 MG/ML subcutaneous injection in people with Saphenous Vein Graft Atherosclerosis, run by Minneapolis Heart Institute Foundation at 4 sites in United States.
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 5 inclusion and 7 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: stopped early, as of the sponsor's last update on 16 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
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 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?
The study was stopped early (reason given: Withdrawal of medication and funding support by Sponsor). Results are not available in the source record.
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?
Nominal change in intermediate SVG lesion percent atheroma volume (PAV) from baseline to 78 weeks post randomization, as assessed by intravascular ultrasonography (IVUS). (time frame: 78 weeks). 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 NCT03542110, which also lists 16 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 Sep 2021.
