Positive Aggrastat Results Featured in the Journal of the American College of Cardiology

Protocol for New Aggrastat Study in American Heart Journal


WINNIPEG, Manitoba - (July 11, 2007) Medicure Inc. (TSX:MPH; Amex:MCU), a cardiovascular focused, biopharmaceutical company, today announced that the two-year, follow-up results from the STRATEGY (Single High-Dose Bolus Tirofiban and Sirolimus-Eluting Stent Versus Abciximab and Bare Metal Stent In Acute Myocardial Infarction) study were published in the July edition of the Journal of the American College of Cardiology (JACC).


The article, titled, "Two-Year Clinical Follow-Up After Sirolimus-Eluting Versus Bare-Metal Stent Implantation Assisted by Systematic Glycoprotein IIb/IIIa Inhibitor Infusion in Patients With Myocardial Infarction", outlines the potential benefit of AGGRASTATR (tirofiban hydrochloride) plus sirolimus-eluting stent (SES) versus ReoproR (abciximab) plus bare-metal stent (BMS) in the prevention of the cumulative incidence of death, myocardial infarction (MI), or target vessel revascularization (TVR) in acute myocardial infarction patients after two years.


At two years, the cumulative incidence of death, MI, or TVR was lower in the AGGRASTATR-SES group compared with the ReoproR-BMS group (24.2% vs. 38.6%, p@038). This statistically significant outcome at two years is similar to the previously reported eight month results that were published in The Journal of the American Medical Association (May 2005).


The positive results from STRATEGY were the impetus for an ongoing larger factorial design study titled MULTI-STRATEGY (Multicentre Evaluation of Single High-Dose Bolus Tirofiban Versus Abciximab and Sirolimus-Eluting Stent Versus Base Metal Stent in Acute Myocardial Infarction). The MULTI-STRATEGY protocol was published in the July edition of the American Heart Journal.


This 600-patient study will further assess AGGRASTATR-SES versus ReoproR-BMS in the prevention of the cumulative incidence of death, MI, and TVR in acute myocardial infarction patients. The results from MULTI-STRATEGY are anticipated to be presented at a prominent scientific symposium in early 2008.


"These papers highlight the ongoing interest in evaluating new investigational uses of AGGRASTATR in the treatment of high risk cardiovascular disease patients," stated Medicure's President and CEO, Albert D. Friesen, PhD. "We believe AGGRASTATR has significant untapped potential, and look forward to the presentation of new data from studies such as MULTI-STRATEGY in the coming year."


Medicure acquired the exclusive U.S. rights to AGGRASTATR, in August 2006.


Important Information About AGGRASTATR AGGRASTATR was approved by the Food and Drug Administration on May 14, 1998.

AGGRASTATR, in combination with heparin, is indicated for the treatment of acute coronary syndrome, including patients who are to be medically managed and those undergoing percutaneous transluminal coronary angioplasty (PTCA) or atherectomy. In this setting AGGRASTATR has been shown to decrease the rate of a combined endpoint of death, new myocardial infarction or refractory ischemia/repeat cardiac procedure. AGGRASTATR has been studied in a setting that included aspirin and heparin.

AGGRASTATR is contraindicated in patients with known hypersensitivity to any component of the product; active internal bleeding or a history of bleeding diathesis within the previous 30 days; or a history of intracranial hemorrhage, intracranial neoplasm, arteriovenous malformation, or aneurysm. Other contraindications to AGGRASTATR include: a history of thrombocytopenia following prior exposure to AGGRASTATR; history of stroke within 30 days or any history of hemorrhagic stroke; major surgical procedure or severe physical trauma within the previous month; history, symptoms, or findings suggestive of aortic dissection. AGGRASTATR is also contraindicated in patients with: severe hypertension (systolic blood pressure greater than 180 mmHg and/or diastolic blood pressure greater than 110 mmHg); concomitant use of another parenteral GP IIb/IIIa inhibitor; or acute pericarditis.

Bleeding is the most common complication encountered during therapy with AGGRASTATR. Administration of AGGRASTATR is associated with an increase in bleeding events classified as both major and minor bleeding events, by criteria developed by the Thrombolysis in Myocardial Infarction Study group (TIMI). Most major bleeding associated with AGGRASTATR occurs at the arterial access site for cardiac catheterization. Fatal bleedings have been reported. AGGRASTATR should be used with caution in patients with platelet count less than 150,000/mm3, in patients with hemorrhagic retinopathy and in patients in chronic hemodialysis. Because AGGRASTATR inhibits platelet aggregation, caution should be employed when it is used with other drugs that affect hemostasis. The safety of AGGRASTATR when used in combination with thrombolytic agents has not been established. During therapy with AGGRASTATR, patients should be monitored for potential bleeding. When bleeding cannot be controlled with pressure, infusion of AGGRASTATR and heparin should be discontinued.
