Preliminary Results of the LIFE Study Presented at VIVA 2015

Improved Patient Outcomes and Compelling Economic Data with the Ovation® Platform and a Fast-Track EndoVascular Aortic Repair (EVAR) Protocol

SANTA ROSA, Calif., Nov. 3, 2015 (GLOBE NEWSWIRE) -- TriVascular Technologies, Inc. (NASDAQ:TRIV), manufacturer of the Ovation Abdominal Stent Graft platform, announced today the presentation of the midterm results of the multicenter Least Invasive Fast-Track EVAR (LIFE) study, during the late breaking clinical trials session at the VIVA 2015 meeting. The results were presented by Zvonimir Krajcer, MD, FACC, Co-Director, Peripheral Vascular Disease Service at Texas Heart Institute in Houston, Texas, who is one of the LIFE Study co-national principal investigators along with Venkatesh G. Ramaiah, MD, FACS, Director of Research at the Arizona Heart Institute and Medical Director of the Arizona Heart Hospital in Phoenix, Arizona.

The LIFE study was initiated to determine the clinical utility and cost effectiveness of the ultra-low profile (14F OD) Ovation Abdominal Stent Graft platform when used under least invasive conditions. The study is a prospective, multicenter registry for the treatment of patients with AAA using a fast-track protocol, consisting of appropriate patient selection, bilateral percutaneous access, avoidance of general anesthesia and intensive care unit admission, and next-day discharge. Patients are enrolled and treated with EVAR if the investigator determines that the patient can meet the fast-track protocol based on medical history and aortoiliac anatomy. Following enrollment, patients remain in the study regardless of whether all components of the fast-track program are completed. Patient outcomes and resource utilization are recorded through hospital discharge and at the 30-day follow-up visit.

The primary endpoint of the study is the proportion of subjects that experience a major adverse event (MAE) within 30 days of the initial procedure. No events have been adjudicated to be an MAE and there have not been any device related serious adverse events reported to date. Secondary endpoints include treatment success, vascular access complications, technical success, hospital stay, quality of life, groin pain, as well as freedom from rupture, conversion, Type I and III endoleaks and migration. The preliminary data from the LIFE Study demonstrate improvement in procedure time and length of stay as compared to a nationwide benchmark of hospitals performing EVAR. Additional economic cost variables to be collected include costs related to anesthesia, access method, and 30-day EVAR re-intervention.

"Preliminary results of the LIFE study are encouraging and demonstrate improved patient outcomes and compelling economic data when utilizing the Ovation platform and a fast-track EVAR protocol," commented Dr. Krajcer. "Dr. Ramaiah and I are excited to partner with TriVascular on this important registry. The results of the LIFE study will significantly contribute to the existing literature and add momentum to the inevitable transition toward a fast-track, next-day discharge EVAR protocol."

A total of 250 subjects will be enrolled in the LIFE study at up to 40 sites in the United States. To date, over 170 patients have been enrolled.

"We are focused on developing products and providing clinical evidence to help expand EVAR access to more patients and improve EVAR outcomes for all patients," said Christopher G. Chavez, Chairman, CEO and President of TriVascular. "We are excited to have reached this major clinical milestone for the LIFE Study and are grateful to all of the study investigators who put their trust in our technology when caring for their patients."

The four-year results of the global Ovation Pivotal Trial were also presented at the late breaking clinical trials session at VIVA 2015 by Manish Mehta, MD, MPH. More information on these data and the Ovation platform can be found on
