Abiomed Announces Results of Impella(R) 2.5 FDA PROTECT I Safety Trial for High-Risk PCI Cases

Abiomed, Inc. (NASDAQ: ABMD) formally announced the results of its Impella® 2.5 PROTECT I safety trial for the first time at the Cardiovascular Research Foundation's (CRF) annual Transcatheter Cardiovascular Therapeutics (TCT) Scientific Symposium and main sessions.

PROTECT I is the first prospective multi-center, FDA-approved trial for prophylactic, or preventative, use of a device during high-risk percutaneous coronary intervention (PCI) procedures. The 20 patient pilot study with the Impella 2.5 met all primary and secondary endpoints and showed very low adverse event rates in a very sick patient population. The results demonstrated no incidents of: aortic valve damage, aortic or mitral dysfunction, sepsis, stroke, thromboembolic events, vascular complications, insertion-site infection, device malfunction, device-related bleeding, limb ischemia, or clinical issues with hemolysis.

"We are pleased to release the successful results of the safety trial at TCT and are excited to begin the pivotal study with an expanded patient population including high-risk PCI with triple vessel disease for patients at up to 150 centers," said Michael R. Minogue, Chairman, CEO and President of Abiomed. "Experience with the Impella 2.5 in the safety trial and in multiple studies in Europe under CE-Mark provides significant evidence of the clinical benefit to patients, and we continue to work with the FDA to bring this breakthrough technology to the U.S."

"In the PROTECT I pilot trial, Impella delivered supreme protection and support. It enabled success in procedures that would have been otherwise impossible," said Dr. J.P.S. Henriques, Cardiologist at the Academic Medical Center in Amsterdam.

Dr. Laura Mauri of Brigham & Women's Hospital also presented new data from the completed PROTECT I trial: "Feasibility Trial Investigating the Use of the Impella 2.5 System in Patients Undergoing High-Risk PCI." An independent Core Lab analysis completed at Duke University determined no damage to the septum, heart chambers, or mitral/aortic valves. At a 30-day follow-up, patients enrolled in the PROTECT I trial showed an improvement of their heart function demonstrated by an absolute increase of 7% in their left ventricular ejection fraction, equating to a 27% relative increase.

"We have been impressed by the ease-of-use and high safety profile of the Impella 2.5 technology during the PROTECT I pilot trial," said Dr. William O'Neill, National Principal Investigator for the pilot and pivotal studies of the Impella 2.5, and Professor and Executive Dean for Clinical Affairs, Division of Cardiology at the Leonard M. Miller School of Medicine at the University of Miami. "With an aging population, Impella will have a significant role in the treatment of high-risk patients, so we are excited to further demonstrate its effectiveness in the recently approved pivotal trial."

Participants from world class centers and investigators for the Impella 2.5 safety trial included: Dr. William O'Neill, Principal Investigator, University of Miami; Dr. Magnus Ohman, Independent Medical Monitor, Duke University; Dr. Simon R. Dixon, William Beaumont Hospital, MI; Dr. Frederic Resnic and Dr. Laura Mauri, Brigham & Women's Hospital, MA; Dr. Igor Palacios, Mass General Hospital, MA; Dr. Andrew Civitello, Texas Heart Institute, TX; Dr. J.P.S. Henriques, Academic Medical Center, Amsterdam, NL; Dr. Paul Teirstein, Scripps Clinic, CA;, NY; and Dr. Michael Collins, New York-Presbyterian Hospital.

Also announced for the first time at TCT was Abiomed's new percutaneous right side catheter that can deliver greater than 4 liters of flow. This product will provide key support to the failing right ventricle and will be introduced first in Europe. More information will be provided in the future.
