What this trial studies

This study evaluates the safety and effectiveness of the Fantom Encore sirolimus-eluting bioresorbable scaffold in patients with de-novo non-complex obstructive coronary lesions. It is a prospective, multicenter, non-randomized study that will include up to 50 participants experiencing stable angina or non-ST elevation acute coronary syndromes. Participants will undergo implantation of the scaffold, with device performance assessed through angiography and optical coherence tomography at the procedure and again at 13 months follow-up.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with stable or unstable angina or non-ST elevation acute myocardial infarction and specific coronary lesion characteristics.

Not a fit: Patients with heavily calcified lesions, severe tortuosity, or those requiring alternative treatment devices may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a safer and more effective treatment option for patients with coronary artery disease.

How similar studies have performed: Previous studies on bioresorbable scaffolds have shown promise, but this specific approach is still being evaluated for its efficacy.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* 18 years or older
* Stable angina, unstable angina or documented silent ischemia (invasive or non-invasive test) or non-ST segment elevation acute myocardial infarction.
* De-novo non-complex coronary obstructive lesions (\>50% stenosis as assessed by quantitative coronary analysis (QCA))
* The patient is willing and able to comply with the specified follow-up evaluations.
* Reference vessel diameter (RVD) ≥ 2.5 mm and ≤ 4.0 mm by QCA.
* During pre-dilatation, the pre-dilatation balloon is uniformly expanded to the full intended diameter.
* Target segment suitable for OCT imaging

Exclusion Criteria:

* Target vessel with a distal Thrombolysis In Myocardial Infarction (TIMI) flow 0 or 1.
* Target lesion located within 5.0 mm of vessel origin.
* Lesion type ACC/AHA C.
* Heavily calcified lesion
* Severe tortuosity
* Target lesion is located in or supplied by an arterial or venous bypass graft.
* Target lesion requires treatment with a device other than the pre-dilatation balloon prior to scaffold placement (including but not limited to directional coronary atherectomy, excimer laser, rotational atherectomy, etc.).
* Unsuccessful pre-dilatation, defined as a residual diameter stenosis ≥ 30%, assessed by QCA.
* Planned future revascularization of non-culprit lesions.
* Presence of another device (stent or scaffold) located within the same segment (5mm from the target lesion borders).
* Patient is currently participating in another study with an investigational device or an investigational drug and has not completed the entire follow-up period.
* Impaired renal function (eGFR \<30ml/min).
* Patient has a contraindication for the use of double antiplatelet therapy for at least 12 months.
* Pregnant or breastfeeding patients.
* Patient has a known allergy to contrast medium, sirolimus, Tyrosine-derived polycarbonate or other structurally related compounds.
* Patient is receiving chronic oral or intravenous immunosuppressive therapy or has known life-limiting immunosuppressive or autoimmune disease (diabetes mellitus is not an exclusion criteria).
* Patient has a co-morbidity, which reduces life expectancy to ≤ 24 months, or social-economic factors making compliance with the study requirements difficult.
