ORLANDO, FL--(Marketwire - November 13, 2011) - The ISAR group, world leading cardiology researchers based in Munich, Germany, today simultaneously presented and published results of the 1,721-patient randomized, double-blind, active-controlled, multicenter ISAR-REACT-4 clinical trial in patients with evidence of evolving infarction (heart attack) undergoing percutaneous coronary interventions (PCI). The Medicines Company announced that the late breaking results were presented at the American Heart Association Scientific Sessions 2011 here today and published in The New England Journal of Medicine.
The study's purpose was to determine whether the combination of unfractionated heparin and abciximab (ReoPro®) is more effective than bivalirudin (Angiox® in Europe, Angiomax® in the United States) in preventing thrombotic and bleeding complications in patients suffering from a heart attack known as non-ST segment elevation myocardial infarctions (NSTEMI) and undergoing PCI.
Principal Investigator Adnan Kastrati, MD of Deutsches Herzzentrum Muenchen presented the results of ISAR-REACT-4, which tested how many patients in each group within 30 days of treatment died, had another major heart attack, required another procedure to unblock the same artery or suffered major bleeding.
- 95 patients (11 percent) taking bivalirudin had at least one of those outcomes compared to 94 (10.9 percent) of those taking abciximab and heparin.
- 22 patients (2.6 percent) on bivalirudin experienced major bleeding compared to 40 patients (4.7 percent) taking abciximab and heparin.
In 2006, the ISAR group reported results of the ISAR-REACT-2 trial that included NSTEMI patients undergoing PCI. In that trial, abciximab plus unfractionated heparin was associated with a significant reduction of ischemic events versus unfractionated heparin in patients with elevated troponin, a cardiac marker of infarction.
Dr. Kastrati stated, "Based on the ISAR-REACT-4 results, a bivalirudin-based strategy should be the standard of care in these high risk patients."
Efthymios Deliargyris, MD, Global Medical Director for The Medicines Company, commented, "The ISAR group has a history of independently minded trials that have driven changes in guidelines and practice across Europe and around the world. We expect that the results from this large trial in PCI patients with evidence of evolving infarction will once again impact the pharmacologic management of these patients."
About Angiomax® (bivalirudin) for Injection
Angiomax is a direct thrombin inhibitor with a naturally reversible mechanism of action and a 25 minute half-life.
In the United States, Angiomax with provisional GPI is indicated in patients undergoing angioplasty, also called PCI, and in patients with, or at risk of, heparin-induced thrombocytopenia and thrombosis syndrome (HIT/HITTS) undergoing PCI. In addition, Angiomax is indicated for use as an anticoagulant in patients with UA undergoing percutaneous transluminal coronary angioplasty (PTCA). Angiomax is intended for use with aspirin. Angiomax is not approved for use in ACS patients not undergoing PCI or PTCA. The most common adverse events for Angiomax in clinical trials comparing Angiomax and heparin were back pain, pain, nausea, headache and hypotension. The incidence of these adverse events was comparable in both the Angiomax and heparin groups in these trials. An unexplained fall in blood pressure or hematocrit, or any unexplained symptom, should lead to serious consideration of a hemorrhagic event and cessation of Angiomax administration. Angiomax is contraindicated in patients with active major bleeding or hypersensitivity to Angiomax or its components. Please see full prescribing information available at http://www.angiomax.com.
In Europe, Angiox currently is indicated as an anticoagulant for adult patients undergoing PCI, including patients with STEMI undergoing primary PCI. Angiox is also indicated for the treatment of adult patients with unstable angina/non-ST segment elevation MI planned for urgent or early intervention.
