NCT ID NCT07286578

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 guide heart stent placement is better than the current standard (IVUS ultrasound) for people with hardened, calcified coronary arteries. About 700 adults with evidence of reduced blood flow to the heart will be randomly assigned to one of the two imaging methods. The goal is to see if CT guidance leads to better stent expansion and similar or fewer heart problems over time.

What this could mean

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

Active substance
CT-guided percutaneous coronary intervention (stent placement) compared to IVUS-guided percutaneous coronary intervention
What this could lead to
If successful, CT guidance could make heart stent procedures faster and more effective for patients with calcified arteries, potentially reducing complications.
What could go wrong
This is a mid-stage trial with 700 participants, so results may not apply to all patients. CT guidance might not improve outcomes or could have unforeseen risks.

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.

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

Inclusion Criteria: * The subject must be at least 18 years of age and younger than 85 years old * Subject must have evidence of myocardial ischemia (e.g., stable angina, silent ischemia (ischemia in the absence of chest pain or other anginal equivalents), unstable angina, or acute myocardial infarction) suitable for PCI. Patients with a clinical indication for revascularization presenting with stable coronary artery disease or stabilized acute coronary syndrome defined as follows unstable angina (Braunwald class IB, IC, IIB, IIC, IIIB, IIIC), patients with NSTEMI without high-risk features such as recurrence of chest pain, ST-segment depression\>1mm in ≥6 leads plus STsegment elevation in aVR, life-threatening arrhythmias, mechanical complications of MI, resuscitated cardiac arrest, GRACE risk score\>140. * All target vessels must have reference vessel diameter (visually assessed by CCTA) ≥ 2.5 mm * Subject must provide written informed consent before any study-related procedure Exclusion Criteria: * STEMI as the clinical presentation. * Uncontrolled or recurrent ventricular tachycardia. * Hemodynamic instability. * Hemodialysis or peritoneal dialysis. * Left main coronary artery stenosis \> 50% * Atrial fibrillation, flutter, or arrhythmias during CT acquisition. * Previous PCI in the target vessel or CABG. * BMI ≥ 40 kg/m2 * Insufficient CT quality assessed by the Core lab. * Comorbidity with life expectancy ≤ 2 years. * Planned major cardiac or non-cardiac surgery within 24 months after the index procedure Note: Major surgery is any invasive operative procedure in which an extensive resection is performed, e.g., a body cavity is entered, organs are removed, or normal anatomy is altered. Note: Minor surgery is an operation on the superficial structures of the body or a manipulative procedure that does not involve a serious risk. Planned minor surgery is not excluded. * The subject has received a solid organ transplant that is functioning or is active on a waiting list for any solid organ transplants with expected transplantation within 24 months. * The subject receives immunosuppressant therapy or has known immunosuppressive or severe autoimmune disease that requires chronic immunosuppressive therapy (e.g., human immunodeficiency virus, systemic lupus erythematosus, etc.). Note: corticosteroids are not included as immunosuppressant therapy. * The subject has previously received or is scheduled to receive radiotherapy to a coronary artery (vascular brachytherapy) or the chest/mediastinum. * Subject has a platelet count \<100,000 cells/mm3 or \>700,000 cells/mm3. * The subject has a documented or suspected hepatic disorder as defined as cirrhosis or Child-Pugh ≥ Class B. * The subject has a history of bleeding diathesis or coagulopathy or has had a significant gastro-intestinal or significant urinary bleed within the past six months. The subject has had a cerebrovascular accident or transient ischemic neurological attack (TIA) within the past six months, or any prior intracranial bleed, or any permanent neurologic defect, or any known intracranial pathology (e.g., aneurysm, arteriovenous malformation, etc. The subject has a life expectancy \<2 years for any non-cardiac cause. * Subject is currently participating in another investigational drug or device clinical study. * Pregnant or nursing subjects and those who plan pregnancy in the period up to 2 years following index procedure. Female subjects of child-bearing potential must have a negative pregnancy test done within 7 days prior to the index procedure per site standard test. * Presence of other anatomic or comorbid conditions, or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow-up requirements, or impact the scientific soundness of the clinical investigation results. * Unable to provide written informed consent (IC).
