On-X LTI to present its newest advance in heart valve technology

On-X Life Technologies to present its newest advance in heart valve technology at the Asian Society for Cardiovascular and Thoracic Surgery (ASCVTS) in Istanbul, Turkey

“We are excited about introducing the On-X^® Plus 1.5™ Aortic Heart Valve to this important surgical society. This valve represents a new paradigm by which clinicians can manage their patients on a reduced dose of warfarin.” – Clyde Baker, CEO, On-X Life Technologies, Inc.

AUSTIN, TX — April 2, 2014 — Privately held On-X^® Life Technologies, Inc. (On-X LTI) announced today that it will introduce the On-X^® Plus 1.5™ Aortic Heart Valve and present the results of the PROACT¹ clinical trial at a company-sponsored luncheon symposium during the upcoming annual scientific meeting of Asian Society for Cardiovascular and Thoracic Surgery (ASCVTS) in Istanbul as part of its international marketing campaign. On-X has been successfully selling mechanical valves in International markets since July 1998.

In January, On-X LTI received European regulatory approval for an expanded labeling claim, which now permits the company to market its breakthrough mechanical heart valve in Europe with a reduced requirement for the use of blood-thinning drugs such as warfarin. The On-X^® Plus 1.5™ Aortic Heart Valve is the only approved mechanical heart valve that allows patients to be managed at an INR (International Normalized Ratio) range between 1.5—2.0. An INR blood test measures the time it takes for patients’ blood to clot.

“We fully expect that our On-X Plus 1.5 Aortic Heart Valve will be rapidly and broadly embraced by heart surgeons throughout Europe and Asia, not only by our current customers but also by new surgeons who want the best mechanical valve for their patients. The On-X valve is the only mechanical valve with a clinically established 60% reduction in bleeding with no increase in thromboembolic events at the lower warfarin dosage in the PROACT clinical trial, an FDA-approved multicenter study with over 1,400 patient years and over 50,000 INR data points,” said Clyde Baker, President and CEO of On-X LTI.

“We have a long history of commitment to physicians and their patients who want the very best, safest mechanical valve available,” added Mr. Baker. “Because it has been shown to be safe to use the On-X mechanical valve with low levels of warfarin, patients and their surgeons now have a new valve alternative, and the initial response from clinicians has been overwhelmingly positive.”

About the On-X^® Prosthetic Heart Valve
The On-X heart valve is the result of a breakthrough in medical grade carbon technology: On-X pure pyrolytic carbon. In addition to providing a more thromboresistant surface, the comparatively high strength of pure On-X Carbon has enabled On-X LTI to make significant valve design changes that have resulted in a prosthesis that acts more like a natural valve in its treatment of blood. Clinical studies have documented that the On-X valve does not produce the turbulence and blood damage commonly produced by other mechanical heart valve prostheses and, therefore, significantly reduces the potential for life-threatening blood clots, which is the basis of the expanded labeling claim recently granted to On-X LTI in the European Union.
