About this study
Official title: Performance of the XLIMUS Sirolimus-eluting Coronary Stent In Very Complex Lesions
Stent delivery failure occurs in 4% of all percutaneous coronary interventions (PCI) and >90% of these failures are due to vessel tortuosity and/or calcification. The XLIMUS eluting coronary stent (CARDIONOVUM GmbH, Bonn, Germany) is a new type of endovascular prostheses characterised by better mechanical properties than traditional DES. This is a prospective, non-randomized, single-center pilot study, aiming to evaluate the performance of the XLIMUS DES in severely complex coronary lesions in real-world clinical practice.
Read the detailed description
All consecutive patients who will undergo elective PCI in native coronary arteries at the Clinica Mediterranea (Naples, Italy) will be considered for eligility. Study participants wiil require to have symptomatic ischemic heart disease attributable to critical (that is, >70% visual estimate) stenotic lesions of native coronary arteries. Inclusion criteria in this pilot study are 1) chronic total occlusion (CTO), 2) severe target vessel calcification, and 3) severe target vessel tortuosity. CTO is defined as the presence of TIMI 0 flow within the occluded segment and angiographic or clinical evidence or high likelihood of an occlusion duration of ≥3 months. Calcification is defined severe when larger than 3x vessel diameter, and comprising the vessel wall totally in two perpendicular views. Tortuosity is defined severe when it satisfies the following criteria: one or more bends of 90° or more, or three or more bends of 45-90° proximal to the diseased segment.
200 patients will be enrolled into the study. Stents will be implanted according to current clinical practice. Techniques attempted for facilitating stent delivery in such a complex lesions are: maximize guide catheter support, optimize predilatation of the stenosis, use of a stiffer guidewire. Specific tricks include: a) buddy-wire; anchoring balloon; GuideLiner catheter. In case of severe calcification, rotational atherectomy will be electively performed with the Rotablator® system (Boston Scientific Corporation, Natick, MA, U.S.A.). Following stent implantation, postdilatation will be performed in all instances with a non-compliant balloon. All patients will receive aspirin 325 mg and clopidogrel (75 mg daily) before stent deployment, with a loading dose (600 mg of clopidogrel) given to patients not pretreated. All patients will receive 70 IU/Kg intra-arterial bolus of unfractionated heparin in order to achieve and activated clotting time >250 seconds. Glycoprotein IIb/IIIa inhibitors will be administered according to operator preference. Estimated glomerular filtration rate (eGFR) will be calculated by applying the Levey Modification of Diet in Renal Disease (MDRD) formula. Chronic kidney disease was defined as a eGFR <60 ml/min/1.73 m2 .
XLIMUS eluting-stent is made of cobalt chromium L 605 and the stent is available in a 6-, 8-, or 10-cell structure design (closed cell architecture). The struts thickness is 73µm. The 6-cell design is for stenting of coronary artery diameter of 2.25mm-2.50mm, 8-cell structure is used for stenting of 2.75-3.50 mm artery diameters, and the 10-cell is for larger artery diameter lesions (up to 5mm). The XLIMUS has an innovative hydrophilic-coated shaft and an extra-low tip profile (crossing profile = 0.90 mm) to access the most tortuous lesions. The highly biocompatible polylactid acid (PLLA) drug containing release matrix degrades smoothly and provides an optimal release kinetic profile. Within 30 days, about 70% of the anti-proliferative drug is distributed into the surrounding arterial tissue of the stent struts, ensuring a highly effective inhibition of smooth muscle cell migration and proliferation. Pharmacokinetic study result confirm sustained anti-proliferative drug efficacy up to 120 days.
The primary objective of the study is the assessment of the clinical performance of the XLILMUS DES, using the following criteria 1) device success, defined as the ability to insert the stent into the target lesion and the attainment of <20% residual stenosis (by visual estimate), 2) lesion success, defined as attainment of <20% residual stenosis of the target lesion using any percutaneous method, and 3) procedural success, defined as lesion success without any in-hospital and MACE.

What is being measured
The primary outcome is the main question the study is designed to answer.
Stent Performance
The primary objective of the study was the assessment of the clinical performance of the XLIMUS DES, using the following criteria 1) device success, defined as the ability to insert the stent into the target lesion and the attainment of <20% residual stenosis (by visual estimate), 2) lesion success, defined as attainment of <20% residual stenosis of the target lesion using any percutaneous method, and 3) procedural success, defined as lesion success without any in-hospital Man 30-day MACE
Measured: up to 1 month
Secondary outcomes (1)
Inhospital, 30-day and 1-year MACE
Major adverse cardiac events included death of any cause, nonfatal myocardial infarction, and repeated revascularization by PCI or surgery occurring within 30-day and 1-year. Myocardial infarction was defined as the presence of pathological and new Q waves on an ECG or as an increase in creatine kinase-myocardial band level to >3 times the upper limit of normal (ULN). Periprocedural myocardial infarction was defined as an increase of troponin I ≥5 times ULN. Target lesion revascularization was defined as a clinically-driven repeat percutaneous coronary angioplasty or coronary artery bypass surgery. Stent thrombosis was defined according to the Academic Research Consortium definitions
Measured: 1 year

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing XLimus in people with Coronary Atherosclerosis Due to Calcified Coronary Lesion and Chronic Total Occlusion of Coronary Artery, run by Clinica Mediterranea at 1 site in Italy.
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 3 inclusion and 1 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: finished, as of the sponsor's last update on 10 May 2016. 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 Italy. 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Stent Performance (time frame: up to 1 month). 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 NCT02360020, which also lists 13 linked publications.
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 10 May 2016; AzTrials last refreshed its copy on 26 Oct 2026.
