Reported at TCT 2012: InspireMD MGuard Stent Meets Primary Endpoint of MASTER Trial, Significantly Improving Prospects of Heart Attack Survival MGuard™ Embolic Protection Stent (EPS) Shows a Significant 29 Percent Improvement in Complete ST Resolution Compared to Bare Metal or Drug Eluting Stents
MIAMI, October 24, 2012 /PRNewswire/ --
InspireMD, Inc. (OTC: NSPR) ("InspireMD" or the "Company"), announced its proprietary MGuard™ Embolic Protection Stent (EPS) was shown to be significantly superior when compared to standard bare metal and drug eluting stents in achieving complete ST resolution and restoring normal blood flow in a major study of 432 randomized patients undergoing emergency coronary intervention for potentially fatal heart attacks.
The data was reported at the Late Breaking Trials Session at the 24th Annual Transcatheter Cardiovascular Therapeutics (TCT) scientific meeting in Miami, FL today by Gregg W. Stone M.D., the study's chairman and the Director of the Cardiovascular Research and Education Center for Interventional Vascular Therapy at New York-Presbyterian Hospital/Columbia University Medical Center.
The findings show the novel MGuard EPS provides a significant acute advantage and, as a result, may hold the potential to lower the incidence of adverse sequela and prolong survival of heart attack victims.
The study met its primary endpoint (proportion of patients with ST segment resolution of≥ 70%, measured at 60 to 90 minutes post procedure), showing the MGuard EPS was significantly superior to the control arm of bare metal and drug eluting stents in the treatment of heart attack patients.
● Significantly more patients treated with the MGuard EPS achieved complete ST resolution (a measure of blood flow restoration to the heart muscle) compared to control arm (57.8% vs. 44.7%, P=0.008), a relative improvement of 29 percent.
● When compared to control, the MGuard EPS showed a significant improvement in coronary artery blood flow, including: (1) superior rates of restoring normal blood flow (TIMI-3 flow) (91.7% vs. 82.9%, P=0.006, a relative improvement of 10.6%); and (2) significantly less incomplete blood flow (TIMI-0/1 flow) post PCI (1.8% vs. 5.6%, P=0.01, a relative improvement of 67.9%).
● The trial showed a trend toward lower mortality (0% vs. 1.9%, P=0.06) at 30 days and smaller infarct size as measured by post procedure cardiac MRI (17.1gr vs. 22.3gr, p=0.27) in the MGuard EPS arm versus control.
● There was no difference between the groups in the secondary endpoint of myocardial blush grade (MBG), which is an angiographic measure of blood flow to the cardiac muscle (MBG2/3 83.9% vs. 84.7%, P=0.81).
"I was impressed with the performance of the MGuard Embolic Protection Stent in the MASTER trial," said Dr. Stone. "Compared to standard stents, the MGuard is the first stent in a randomized trial shown to restore complete ST-segment resolution in a higher proportion of patients, a key predictor of myocardial salvage and long-term survival in STEMI (ST segment elevation myocardial infarction) patients."
The MGuard EPS is integrated with a precisely engineered micro net mesh that prevents the unstable arterial plaque and thrombus (clots) that caused the heart attack blockage from breaking off.
Results Published In Journal of American Cardiology
The MASTER (MGuard for Acute ST Elevation Reperfusion) trial randomized 432 patients to MGuard EPS (217) and to either bare metal or drug eluting stents (216). Fifty centers in nine countries participated in the trial. Patients are being followed for one year.
Details of the MASTER trial were published online today in the Journal of American College of Cardiology (JACC).
The authors concluded that "among patients with acute STEMI undergoing emergent PCI enrolled in the present multicenter, randomized, controlled trial, the MGuard EPS micro net covered stent compared to standard metallic stents resulted in superior rates of epicardial coronary flow and complete STR, with trends present toward reduced microvascular obstruction, infarct size and mortality."
About Stenting And MGuard EPS
Stenting is a routine procedure for heart attack patients. It opens up the clogged artery that caused the attack.
Standard stents weren't engineered for heart attack patients. They were designed for treating stable angina patients whose occlusion is different from that of an occlusion in a heart attack patient.
In acute heart attack patients the plaque or thrombus is unstable and often breaks up as the stent is implanted causing downstream blockages (some of which can be fatal) in a significant portion of heart attack patients.
InspireMD's solution is the MGuard EPS, a metal stent that's secured inside a proprietary knitted net made of micro polymer fibers, each thinner than a human hair.
The Micronet™ is designed to hold plaque or thrombus in place against the blocked artery's wall, preventing debris from entering the blood stream.
While offering superior performance relative to standard stents in STEMI patients, the MGuard EPS requires no change in current physician practice - an important factor in promoting acceptance and general use in time-critical emergency settings.
MGuard™ EPS is CE Mark approved.
