Study summary

The main aim of this trial is to demonstrate that Evolocumab plus routine lipid management is superior to routine lipid management alone in modifying plaque (non-calcified) volume as measured by Artificial Intelligence-enabled Quantitative Coronary Plaque Analysis (AI-QCPA) from Coronary Computed Tomography Angiography (CCTA).

Inclusion criteria

  • At screening, one of the two following conditions must be met: Evidence of established CAD as demonstrated by: Prior non-invasive imaging modality that demonstrates at least one major epicardial vessel with mild-to-moderate obstruction (Coronary Artery Disease Reporting and Data System (CAD-RADS) 1-3) OR Presence of an abnormal coronary artery calcium (CAC) score > 50 OR Positive stress test indicative of suspected CAD OR Presumed CAD as determined by presence of at least one of the following conditions: Known history of diabetes mellitus (DM; type 1 or 2) with at least one of the following: DM requiring insulin therapy OR DM disease onset ≥ 5 years ago OR DM with evidence of end-organ damage such as diabetic retinopathy, neuropathy, or nephropathy OR Known history of peripheral artery disease due to atherosclerosis or carotid artery atheroma.
  • Low-density Lipoprotein cholesterol (LDL-C) of at least 70 milligrams per deciliter (mg/dL).
  • Patients with Intermediate pre-test probability of obstructive coronary artery lesions.
  • Minimal total plaque volume (TPV) of 100 cubic millimeters (mm\^3) measured during baseline AI-QCPA.
  • Must be on stable lipid-lowering therapy for at least 6 weeks, with no planned changes and no plans to initiate Proprotein Convertase Subtilisin/Kexin type 9 ( PCSK9) inhibition.

Exclusion criteria

Exclusion Criteria:

  • Lifetime history of myocardial infarction (MI), ischemic stroke, or coronary revascularization.
  • Symptomatic coronary artery disease or stable chronic coronary artery disease that, in the opinion of the investigator, meets criteria for urgent or elective revascularization procedures (coronary artery bypass grafting or percutaneous coronary intervention).
  • Planned cardiac surgery, arterial revascularization, or planned major non-cardiac surgery during the study period.
  • to performing serial CCTA imaging such as: Severe renal insufficiency (estimated (eGFR) \< 30 milliliters per minute per 1.73 square meters (30 mL/min/1.73 m\^2) History of to iodinated contrast Body weight and/or body circumference that prevent safe and successful Computed Tomography (CT) imaging, in the opinion of the investigator; Other patient-related factors that may interfere with diagnostic quality of CCTA images including: Atrial fibrillation Heart rate >60-70 beats per minute; Tachycardia or significant arrhythmia that cannot be adequately controlled with medications to allow CCTA Irregular rhythm (including Premature Ventricular Contraction (PVCs)); Inability to sustain a breath hold for at least five seconds.
  • Prior history of PCSK9 inhibitor treatment within the past 12 months or known lifetime discontinuation of prior PCSK9 inhibitor due to adverse reaction, lack of tolerability, or lack of treatment response.
  • History or evidence of any other disorder, condition (including incidental CCTA findings), or disease that, in the opinion of the investigator, would pose a risk to participant safety.
  • CCTA showing any of the following: Total occlusion OR Lesion-specific FFRct value ≤ 0.80 OR Diameter stenosis of the left main coronary artery >50 % OR Diameter stenosis of all three major coronary arteries >50%.
  • CCTA not meeting established imaging criteria after two attempts during the baseline CCTA visit as assessed by the central imaging laboratory.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

References and documents

Individual participant data

Plan to share: Yes — De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request.

Supporting information: Study protocol, Statistical analysis plan, Informed consent form, Clinical study report

Time frame: Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.

Access criteria: Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors. If not approved, a Data Sharing Independent Review Panel will arbitrate and make the final decision. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jan 2027; primary completion for Apr 2029, 26 months later.

Of 193 phase 4 interventional studies under Coronary Artery Disease, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 19 and three quarters within 58. This study's planned 26 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 21, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
