Positive Results of InspireMD's MASTER Trial to be Published on November 6 in Journal of American College of Cardiology
432-Patient Study of New MGuard™ Stent Met Primary Endpoint; Significantly Improved Likelihood of Heart Attack Survival
TEL AVIV, Israel, November 5, 2012 /PRNewswire/ --
InspireMD, Inc. ("InspireMD" or the "Company") (OTC: NSPR) announced today that the randomized 432-patient MASTER trial of its embolic protective MGuard stent will be published in the November 6, 2012 print edition of the peer-reviewed Journal of American College of Cardiology, Vol. 60, No. 19.
The online version of the paper, authored by Gregg W. Stone, MD and others, appeared a week ago Wednesday (October 24) at: http://content.onlinejacc.org/article.aspx?articleid=1377008, coinciding with Dr. Stone's presentation of the findings at the Late Breaking Clinical Trials session of the 24th Annual Transcathater Cardiovascular Therapeutics (TCT) scientific meeting in Miami, October 22-26.
The findings showed the novel MGuard EPS provided a statistically and clinically 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.
MGuard EPS is CE Mark approved. It is not approved for sale in the U.S. by the Food and Drug Administration (FDA) at this time. The Company plans to initiate a FDA approval study in 1Q 2013.
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 the control arm (57.8% vs. 44.7%, P=0.008), a relative improvement of 29 percent.
-- The MGuard EPS showed a significant improvement in coronary artery blood flow compared with the control, 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%).
Although the study's secondary endpoints were not powered for statistical significance, they showed positive trends.
-- 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, which is an angiographic measure of blood flow to the cardiac muscle (MBG2/3 83.9% vs. 84.7%, P=0.81).
The MASTER (MGuard for Acute ST Elevation Reperfusion) trial randomized 432 patients to MGuard EPS (217) and 216 to either bare metal stents (60%) or drug eluting stents (40%). Fifty centers in nine countries participated in the trial. Patients are being followed for one year.
Dr. Stone, the study's chairman, is the Director of the Cardiovascular Research and Education Center for Interventional Vascular Therapy at New York-Presbyterian Hospital/Columbia University Medical Center.
About Stenting and MGuard EPS
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.
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.
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.
About InspireMD, Inc.
InspireMD is a medical device company focusing on the development and commercialization of its proprietary stent system technology, MGuard™. InspireMD intends to pursue applications of this technology in coronary, carotid and peripheral artery procedures. InspireMD's common stock is quoted on the OTC under the ticker symbol NSPR.
About MGuard™ Embolic Protection Coronary Stent
MGuard™ EPS combines a coronary stent merged with an embolic protection specifically designed for acute MI patients. The embolic protection is comprised of an ultra-thin polymer micron net that is integrated with the stent. The MGuard EPS is designed to provide outstanding and lifelong embolic protection, without affecting deliverability. MGuard EPS is CE Mark approved. MGuard™ is not approved for sale in the U.S. by the U.S. Food and Drug Administration at this time.
