February 17, 2024 updated by: Julio Ivan Farjat Pasos, Instituto Nacional de Cardiologia Ignacio Chavez

Randomized Trial Investigating Clinical Outcomes of Two Sirolimus-Eluting Stents in Diabetes Mellitus

Randomized, controlled, blind, single-center and non-inferiority clinical trial to compare the target lesion failure (TLF) at 12 months in patients with diabetes mellitus who underwent percutaneous coronary intervention with an Orsiro stent vs. Abluminus stent.

Study Overview

Detailed Description

Worldwide, and especially in Mexico, there is a high incidence of diabetes mellitus (DM), which in turn, confers a higher cardiovascular risk in this population. Diabetic patients undergoing PCI have worse outcomes than non-diabetics regardless of the degree of complexity of their coronary anatomy. Although the 30-day in-hospital outcomes have been similar between diabetic and non-diabetic patients, DM has been invariably associated with greater stent failure with target vessel revascularization (TVR), major adverse cardiovascular event (MACE), and mortality in the long-term follow-up, even with the use of drug-eluting stents. In relation to the above, two of the sirolimus-eluting stents (SES): the Abluminus and the Orsiro, have been considered as promising options in patients with DM. The Abluminus stent has been designed for diabetic patients in order to reduce cardiovascular events. Said stent consists of a cobalt-chromium platform covered with a layer of biodegradable polymer and mounted on a balloon, both sirolimus-releasing. The Rate of target lesion failure (TLF) reported to date in diabetic patients is 3.8%. On the other hand, the Orsiro stent, a cobalt-chromium platform with ultrathin struts, has had favorable results in different clinical settings and patients with different characteristics]; specifically in a subgroup analysis in DM, a TLF rate of 3.5% was reported

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Abluminus Sirolimus Eluting Stent System (ASES)
The Abluminus sirolimus eluting stent manufactured by Envision and distributed by Concept Medical.

The procedure will be conducted in accordance with the CE mark instructions for use for the ASES.

The need or not for postdilation in any segment of the stent will be at the discretion of the operator, seeking its adequate expansion and apposition. To consider PCI to be successful, residual stenosis must be less than or equal to 30% by angiography at the end of the procedure, including the absence of coronary dissection that compromises distal flow or a hemodynamically significant pressure gradient across the lesion.

Experimental: Orsiro Sirolimus Eluting Coronary Stent System (OSES)
The Orsiro sirolimus eluting stent manufactured by Biotronik.

The procedure will be conducted in accordance with the CE mark instructions for use for the OSES.

The need or not for postdilation in any segment of the stent will be at the discretion of the operator, seeking its adequate expansion and apposition. To consider PCI to be successful, residual stenosis must be less than or equal to 30% by angiography at the end of the procedure, including the absence of coronary dissection that compromises distal flow or a hemodynamically significant pressure gradient across the lesion.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Cardiovascular Death
Time Frame: 12 months

Cardiovascular death is defined as death resulting from cardiovascular causes. The following categories may be collected:

  • Death resulting from heart failure
  • Death caused by stroke
  • Death caused by cardiovascular procedures
  • Death resulting from cardiovascular hemorrhage
  • Death resulting from other cardiovascular cause

    • Any MI not clearly attributable to a non-target vessel will be considered as target-vessel MI.
    • Percutaneous coronary intervention (PCI) related MI is termed type 4a MI.
    • Coronary artery bypass grafting (CABG) related MI is termed type 5 MI. Revascularization is clinically driven if the target lesion diameter stenosis is > 50% by quantitative coronary angiography (QCA) and the subject has clinical or functional ischemia which cannot be explained by another native coronary or bypass graft lesion.
12 months
Myocardial Infarction (MI)

(according to the 4th international definition of myocardial infarction) detection of an increase or decrease in cardiac troponin values with at least 1 of the values above the upper reference limit of the 99th percentile and at least 1 of the following conditions :

  • Symptoms of acute myocardial ischemia.
  • New ischemic changes in the electrocardiogram.
  • Appearance of pathological Q waves.
  • Imaging evidence of loss of viable myocardium or new regional abnormalities in myocardial wall mobility following a pattern compatible with ischemic etiology.
  • Identification of a coronary thrombus by angiography with intracoronary imaging or by autopsy

    • Any MI that cannot be clearly attributed to a vessel other than the revascularized one will be considered as MI related to the treated vessel.
12 months
Target Lesion Revascularization (TLR)
Time Frame: 12 months
Revascularization is clinically driven if the target lesion diameter stenosis is > 50% by quantitative coronary angiography (QCA) and the subject has clinical or functional ischemia which cannot be explained by another native coronary or bypass graft lesion.
12 months

Time Frame: 12 months
TVR is a repeat percutaneous intervention of the target lesion or bypass surgery of the target vessel performed for restenosis or other complication of the target lesion.
12 months
Target vessel failure (TVF)
Time Frame: 12 months
To compare the rate of target vessel failure (composed of cardiovascular death, myocardial infarction related to the treated vessel or ischemia driven target vessel revascularization)

Time Frame: 12 months

Compare death from any cause between the two groups.

The following categories will be collected:

  • Malignancy.
  • Pulmonary causes.
  • Infection.
  • Gastrointestinal causes.
  • Accident / trauma.
  • Caused by failure of another non-cardiovascular organ.
