Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The present clinical investigation is designed as a prospective, multicentre, international, randomized, open label, 2-arm parallel group, trial in patients undergoing Percutaneous Coronary Intervention (PCI) comparing Xlimus DES versus Synergy DES with respect to optical coherence tomography (OCT) derived measures at 6-month Follow Up (FU) and clinical events at 12 months after procedure. A total of 180 patients will be recruited and randomized in the two groups in a 2:1 ratio. After index procedure, patients will be followed up by angiographic follow-up at 6 months and clinical follow-up at 12 months.The primary endpoint will be independently evaluated by the Core-Lab which will be blinded as to group assignment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  7. Non-cardiac co-morbid conditions with life expectancy <1 year or that may result in protocol non-compliance (per site investigator's medical judgment);
  8. Patients who are actively participating in another drug or device investigational study, which have not completed the primary endpoint follow-up period;
  9. Previously documented left ventricular ejection fraction (LVEF) <30%;

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
In-stent neointimal volume
Time Frame: 6-month follow-up
In-stent neointimal volume at 6-month follow-up, measured with OCT, as assessed by the Core-Lab. Neointimal volume will be calculated in all analyzed cross-sections and volumetric measurements and in stent neointimal volume will be compared in the two groups.
6-month follow-up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Time Frame: 12-months follow-up
any MI that, irrespective of the time after the index procedure, is related to documented acute ischemia in the territory of the implanted stent without angiographic confirmation of stent thrombosis and in the absence of any other obvious cause. Type of acute MI is classified according to the Joint ESC/ACCF/AHA/ WHF Joint Task Force for the Universal Definition of Myocardial Infarction
