What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether using a CT scan to plan a heart stent procedure (PCI) makes it faster, safer, and more effective than the usual approach. About 200 adults with coronary artery disease will either get CT-guided planning or standard care. Researchers will compare procedure time, radiation exposure, and contrast dye use, and follow participants for one year.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Coronary computed tomography angiography (CCTA)-guided procedural planning
What this could lead to
If successful, this could make coronary stenting faster, safer, and more precise by using CT scans to plan the procedure beforehand.
What could go wrong
This is an early-stage feasibility study with only 200 participants, so results may not apply to all patients. The CT-based plan may not always match what the doctor sees during the procedure.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 200 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

May 2026

An estimate. Start dates often move.

Expected to finish

Dec 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged 18 to 80 years * Ability to provide written informed consent * Patients undergoing coronary computed tomography angiography (CCTA) for suspected coronary artery disease or for diagnostic work-up of stabilized acute coronary syndrome * Presence of at least one target coronary lesion meeting one of the following CCTA criteria: * Severe coronary diameter stenosis (70-99%) in one or more coronary arteries according to CAD-RADS 4A or 4B classification and at least one of the following: * CT-derived fractional flow reserve (CT-FFR) ≤0.80 * At least 2 high-risk plaque characteristics, including: * Low attenuation plaque density \<30 Hounsfield units * Positive remodeling index \>1.1 * Napkin-ring sign * Spotty calcification * Left main coronary artery stenosis ≥50% * Ostial or proximal left anterior descending artery, dominant left circumflex artery, or dominant right coronary artery stenosis ≥50% and at least one of the following: * CT-FFR ≤0.80 * At least 2 high-risk plaque characteristics, including: * Low attenuation plaque density \<30 Hounsfield units * Positive remodeling index \>1.1 * Napkin-ring sign * Spotty calcification * Planned clinically indicated invasive coronary angiography with operator decision to proceed with PCI Exclusion Criteria: * Contraindication to iodinated contrast media, including severe allergy or contrast-induced nephropathy * Poor-quality or non-diagnostic CCTA imaging * Target lesions involving in-stent restenosis * Chronic total occlusion target lesions * Operator decision to treat a vessel not identified as a target vessel by the CCTA core laboratory analysis * Pregnancy or breastfeeding * Patients referred for coronary artery bypass graft surgery after invasive coronary angiography * Participation in another investigational drug or drug-coated device study * Inability to provide informed consent
