WINNIPEG, MANITOBA--(Marketwire - Oct. 2, 2012) - Medicure Inc. ("Medicure" or the "Company") (MPH.V)(MCUJ), is pleased to announce its intention to file a supplemental new drug application (sNDA) for the high dose bolus (HDB) dosing regimen of AGGRASTAT(R) (tirofiban HCl). The Company also announces that the United States Food and Drug Administration (FDA) has granted the Company's request for a waiver of the US $979,400 application fee for the planned sNDA.
The planned sNDA submission is to request the addition of the AGGRASTAT HDB regimen (an initial bolus of 25 mcg/kg and then continued at 0.15 mcg/kg/min) to the approved prescribing information for AGGRASTAT. The rationale for the AGGRASTAT HDB regimen is to attain therapeutic platelet inhibition more rapidly than the currently approved dosing regimen (an initial rate of 0.4 mcg/kg/min for 30 minutes and then continued at 0.1 mcg/kg/min).
Bolus dosing is the most common approach to administering a glycoprotein IIb/IIIa inhibitor (GPI)(1). Since AGGRASTAT is the only GPI that does not have an FDA approved bolus dosing regimen, the addition of the HDB regimen would better position the product to compete in the contemporary market.
In communication with the Company, the FDA's Division of Cardiovascular and Renal Drug Products has indicated its willingness to review and evaluate this label change request based substantially on published studies involving the AGGRASTAT HDB regimen. The efficacy and safety of the HDB regimen has been evaluated in more than 20 clinical studies involving over 7,000 patients and is currently recommended by the ACCF/AHA treatment guidelines (2), (3), (i).
In September 2010 the AGGRASTAT HDB regimen was approved in the European Union. AGGRASTAT is the most used GPI outside of the United States(1). The Company's subsidiary, Medicure International, Inc. (Barbados) holds the rights to AGGRASTAT in the United States and its territories.
The Company anticipates filing the sNDA before the end of calendar 2012, which will result in a Prescription Drug User Fee Act (PDUFA) action date for the AGGRASATAT HDB sNDA in the second half of 2013. Under PDUFA, the FDA aims to complete its review within ten months from the receipt of an sNDA submission.
The United States Federal Food, Drug and Cosmetic Act (the Act) stipulates that sponsors requesting a label change for a prescription drug must pay a user fee prior to consideration of the sNDA. As of October 2012, the amount of the user fee for the sNDA submission is US $979,400. The Company applied for and was successful in receiving a waiver of this application fee under the barrier-to-innovation provision of the Act, therefore it is not required to pay any user fee for applications submitted within the next 12 months.
AGGRASTAT (tirofiban HCl), in combination with heparin, is indicated for the treatment of acute coronary syndrome, including patients who are to be managed medically and those undergoing PTCA or atherectomy. In this setting, AGGRASTAT has been shown to decrease the rate of a combined endpoint of death, new myocardial infarction or refractory ischemia/repeat cardiac procedure. AGGRASTAT has been studied in a setting that included aspirin and heparin.
Bleeding is the most common complication encountered during therapy with AGGRASTAT. Administration of AGGRASTAT 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 AGGRASTAT occurs at the arterial access site for cardiac catheterization. Fatal bleedings have been reported. AGGRASTAT should be used with caution in patients with platelet count less than 150,000/mm3, in patients with hemorrhagic retinopathy, and in chronic hemodialysis patients. Because AGGRASTAT inhibits platelet aggregation, caution should be employed when it is used with other drugs that affect hemostasis. The safety of AGGRASTAT when used in combination with thrombolytic agents has not been established. During therapy with AGGRASTAT, patients should be monitored for potential bleeding. When bleeding cannot be controlled with pressure, infusion of AGGRASTAT and heparin should be discontinued.
AGGRASTAT is a parenteral non-peptide, reversible GP IIb/IIIa receptor antagonist that is marketed in the United States by Medicure Pharma, Inc. Please see the AGGRASTAT Prescribing Information for approved indications, dosage regimens and safety related information.
The AGGRASTAT HDB dosing regimen discussed in this press release has not been approved by the FDA.
