Ziltivekimab to reduce coronary plaque after a heart attack

Effects of Ziltivekimab Versus Placebo on Coronary Atherosclerosis in Patients With Acute Myocardial Infarction. A Serial, Multivessel, Intravascular Ultrasound, Near-infrared Spectroscopy and Optical Coherence Tomography Imaging Study

Phase 3 Interventional ECRI bv · NCT07276282

This study will test whether the anti-inflammatory drug ziltivekimab can reduce plaque buildup and improve plaque composition in people who recently had a heart attack and were treated with PCI.

What this trial studies

This Phase 3, randomized trial gives people who recently had an acute myocardial infarction either ziltivekimab or placebo on top of standard care and uses advanced intracoronary imaging to look directly at plaque burden and composition. Imaging methods such as intravascular ultrasound (IVUS), near-infrared spectroscopy (NIRS), and optical coherence tomography (OCT) are used to measure changes in treated and non-culprit coronary segments. Participants must have had PCI for the culprit lesion and at least two other native coronary segments suitable for imaging immediately after the qualifying procedure. The study aims to link changes in plaque biology with IL-6 pathway inhibition over the study period to see if reducing inflammation favors plaque stabilization.

Who should consider this trial

Good fit: Adults aged 18 or older who have had an acute myocardial infarction treated with PCI and who have at least two native coronary segments suitable for intracoronary imaging are ideal candidates.

Not a fit: Patients with left-main or three-vessel disease, prior coronary bypass surgery, very calcified or tortuous arteries that prevent imaging, or unstable clinical status are unlikely to be eligible or to benefit from this protocol.

Why it matters

Potential benefit: If successful, ziltivekimab could reduce arterial plaque burden and stabilize plaques, which may lower the risk of recurrent heart attacks.

How similar studies have performed: Anti-inflammatory approaches such as IL-1β inhibition and colchicine have reduced cardiovascular events in prior trials, while direct IL-6 blockade is less established clinically though early-phase studies show strong reductions in inflammatory markers.

Eligibility criteria

Key Inclusion Criteria:

* Informed consent obtained before any study-related activities.
* Age 18 years or above at the time of providing informed consent.
* Acute myocardial infarction, with at least one coronary segment (culprit lesion) treated with PCI.
* At least two major native coronary arteries each meeting angiographic criteria for intracoronary imaging immediately following the qualifying PCI procedure.

Key Exclusion Criteria:

* Known or suspected hypersensitivity to study intervention(s) or related products.

* Estimated life expectancy less than 2 years
* Received a live or attenuated-live vaccine product within 4 weeks of study intervention administration or expected to receive a live or attenuated-live vaccine product during the treatment period.
* Major cardiac surgical within the past 60 days or any major surgical procedure planned at the time of randomisation or as treatment for the current AMI (CABG).
