Medicure Announces Early Completion of Enrollment for iSPASM, a Phase 1/2a Exploratory Clinical Trial of AGGRASTAT® (tirofiban hydrochloride) Injection vs. Placebo for Induced Suppression of Platelets Activity in Aneurysmal Subarachnoid Hemorrhage Management

WINNIPEG, MB, Jan. 27, 2021 /PRNewswire/ - Medicure Inc. ("Medicure" or the "Company") (TSXV: MPH) (OTC: MCUJF), a cardiovascular pharmaceutical company, is pleased to announce the early completion of iSPASM, a randomized, double-blind, single-center, Phase 1/2a trial aimed at assessing the safety of long-term (7-day) use of AGGRASTAT^® (tirofiban hydrochloride) injection (an intravenous GP IIb/IIIa inhibitor) vs. placebo in patients with aneurysmal subarachnoid hemorrhage (aSAH) (NCT03691727). The primary endpoint in the 30 patient study was hemorrhagic changes evident on head CT and/or MRI assessed by the rates of symptomatic and asymptomatic bleeding.

"Medicure is gratified and encouraged by the results of the trial led Dr. David Hasan, MD, Professor of Neurosurgery at University of Iowa Hospitals and Clinics, and the trial's principal investigator. His work is an important step in the exploration of the use of parenteral IV antiplatelet therapy in the management of aSAH in stroke patients.", said Albert D. Friesen, PhD, CEO of Medicure and Chair of its Board of Directors. Dr. Hasan expects to release top-line data and present the results at an upcoming conference with a manuscript to follow.

Dr. Hasan states, "The results of iSPASM are very promising. The trial is the first of its kind as it showed in a well-designed, randomized controlled trial that using continuous IV infusion of AGGRASTAT^® appears to be safe in patients with ruptured intracranial aneurysms (stroke). Results from this study pave the way for a Phase 2 trial which will be focused on efficacy. A positive outcome will be groundbreaking in the management of these patients. Interventionalists who treat patients with this condition using stents or flow diverters could use AGGRASTAT^® as the choice of antiplatelet therapy to prevent clotting and further ischemic stroke. We are very grateful for the sponsorship and partnership with Medicure for making this trial happen to benefit our patients."

iSPASM was funded by an unrestricted educational grant from Medicure. This study does not imply efficacy of AGGRASTAT^® in patients with aSAH. Please note that the use of AGGRASTAT^® in neurointerventions has not been approved by the FDA. As of this time, neither AGGRASTAT^® nor any of the GP IIb/IIIa inhibitors are indicated for the use in stroke patients. AGGRASTAT^® is approved for use in NSTE-ACS patients. Refer to Important Safety Information below and the U.S. Prescribing Information for complete product information.

Important Safety Information for AGGRASTAT^® (tirofiban hydrochloride)

Indications and Usage
AGGRASTAT^® is indicated to reduce the rate of thrombotic cardiovascular events (combined endpoint of death, myocardial infarction, or refractory ischemia/repeat cardiac procedure) in patients with non-ST elevation acute coronary syndrome (NSTE-ACS).

Dosage and Administration
Administer intravenously 25 mcg/kg within 5 minutes and then 0.15 mcg/kg/min for up to 18 hours. In patients with creatinine clearance ≤60 mL/min, give 25 mcg/kg within 5 minutes and then 0.075 mcg/kg/min.

Contraindications
Known hypersensitivity to any component of AGGRASTAT^®, history of thrombocytopenia with prior exposure to AGGRASTAT^®, active internal bleeding, or history of bleeding diathesis, major surgical procedure or severe physical trauma within previous month.

Warnings and Precautions 
AGGRASTAT^® can cause serious bleeding. Most bleeding associated with AGGRASTAT^® occurs at the arterial access site for cardiac catheterization. Minimize the use of traumatic or potentially traumatic procedures such as arterial and venous punctures, intramuscular injections, nasotracheal intubation, etc. Concomitant use of fibrinolytics, anticoagulants and antiplatelet drugs increases the risk of bleeding. If bleeding cannot be controlled, discontinue AGGRASTAT^®.
