Safety and Efficacy Study of MGuard Stent After a Heart Attack (MASTER)

May 28, 2013 updated by: InspireMD

MASTER: MGUARD for Acute ST Elevation Reperfusion

The goal of this study is to demonstrate the superiority of the MGuard™ stent over commercially-approved bare-metal (BMS) /drug-eluting stents (DES) in achieving better myocardial reperfusion in primary angioplasty for the treatment of acute ST-elevation myocardial infarction (STEMI).

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years and older (Adult, Older Adult)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: MGuard
MGuard stent will be deployed
Device: MGuard
MGuard™ stent comprises a balloon-expandable, thin-strut stainless steel (316L) bare metal stent platform (strut width 100 µm) with mesh sleeve fibers of polyethyleneterephtalate (fiber width of 20 µm) attached to its outer surface. These fibers act like a net (aperture size 150 x 180 µm) preventing distal embolization of the plaque debris/thrombus placed between the vessel wall and the stent.
Active Comparator: BMS or DES
A regular bare metal stent or drug-eluting stent will be deployed
Device: Control BMS or DES
Control BMS or DES

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
Time Frame
The incidence of complete ST segment resolution (defined as ≥70% ST 1. The incidence of complete ST segment resolution
Time Frame: 60 to 90 minutes after the last angiogram
60 to 90 minutes after the last angiogram

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.
Outcome Measure
Measure Description
Time Frame
The incidence of Thrombolysis In Myocardial Infarction (TIMI) 3 flow at the end of the procedure.
Time Frame: 60-90 minutes after last angiogram
The incidence of TIMI 3 flow at the end of the procedure.
60-90 minutes after last angiogram
Major Adverse Cardiac Events (MACE)at discharge, 30 days, 6 months and 12 months post-procedure
Time Frame: discharge, 30 days, 6 and 12 months post-procedure
Major Adverse Cardiac Events (MACE): defined as cardiac death, reinfarction (Q wave and non-Q wave), or repeat ischemia-driven target lesion revascularization (TLR) by percutaneous or surgical methods at hospital discharge, 30 days, 6 months and 1 year post-procedure.
discharge, 30 days, 6 and 12 months post-procedure

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
