  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patients with NSTEMI undergoing subacute PCI in native vessels and to be treated with one or more drug eluting stents in coronary arteries due to a visually assessed significant culprit lesion with > 50% of coronary stenosis at the catheterization laboratory in Odense.

About this study

Official title: Coronary Artery Healing Process After BiOresorbable Scaffold iN PatiEnts With Non-ST-Segment Elevation Myocardial Infarction (NSTEMI)

To compare coronary healing after optical coherence tomography guided versus conventionally angiography guided percutaneous coronary intervention with the Magmaris bioresorbable scaffold.

Read the detailed description

BACKGROUND:

Bioresorbable scaffolds (BRS) represent a novel approach during percutaneous coronary intervention (PCI), which provides transient vessel support with drug-delivery capability without the long-term limitations (very late stent thrombosis) of the metallic drug-eluting stents. Patients with Non-ST-segment elevation myocardial infarction (NSTEMI) often feature thrombus-rich lesions with large necrotic core, which may be associated with delayed arterial healing and impaired stent-related outcomes. Besides clinical indication and underlying plaque morphology, sufficient and potent strut coverage depends on several additional factors (patient characteristics, stent type and procedural factors). Particularly, acute incomplete stent apposition is a strong procedural risk factor for later deficient neointimal coverage. Optical coherence tomography (OCT) is a high-resolution intravascular imaging modality, that enables in-vivo evaluation of the immediate stenting result, and the vascular healing pattern including strut coverage at follow-up.

AIM:

The objective of this study is to investigate if OCT-guided Magmaris BRS implantation in patients with NSTEMI can improve the coronary arterial healing at 6 months compared to routine angiographic guidance only. Further to investigate if the plaque composition/lipid content will influence on the vascular healing.

METHOD:

The study is designed as a prospective, randomized trial. After pre-dilation, patients will be randomly assigned to either: (1) OCT-guided PCI, or (2) angio-guided PCI with Magmaris BRS implantation. In the OCT-guided group, OCT will be used for vessel and BRS sizing. After Magmaris BRS implantation the result will be controlled with OCT and: 1) BRS under expansion and/or, 2) strut malapposition and/or, 3) edge dissection- and/or 4) residual stenosis at the distal and/or proximal reference segment(s) that may require further intervention. A final OCT will be performed in case of re-intervention.

In the angio-guided group an OCT will be performed only after angiography final and acceptable result.

A follow-up OCT will be performed after 6 months in all patients to assess the vascular healing and a vasomotor test will be performed in half of the patients. After 12 months the dynamic changes in vascular healing will be assessed in the first enrolled half of the patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Coronary artery healing score

    The primary endpoint is coronary artery healing score assessed by OCT Healing score is a weighted index that combines the following components: Uncovered scaffold struts, Uncovered "jailed" and acquired or persistent malapposed struts, Persistent mal apposition, Acquired mal apposition, Maximum neointimal growth and Accumulated extra stent lumen

    Measured: 6 months

Secondary outcomes (2)
  1. Coronary artery healing

    Secondary endpoints are all individual components of coronary artery healing score

    Measured: 6 and 12 months.

  2. Coronary artery healing

    Vasomotion at 6 months

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing OCT guided PCI and Angiography guided PCI in people with Myocardial Infarction and Coronary Artery Disease, run by Odense University Hospital at 1 site in Denmark.

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 1 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 2 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

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?

Coronary artery healing score (time frame: 6 months). 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 NCT03016624, which also lists 1 linked publication.

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 2 Mar 2021.
