HeartWare Announces Early Conclusion of Enrollment for U.S. Bridge-to-Transplant Clinical Trial
FRAMINGHAM, Mass. and SYDNEY, Feb 22, 2010 /PRNewswire via COMTEX/ -- HeartWare International, Inc. (Nasdaq: HTWR; ASX: HIN), a leading innovator of less invasive, miniaturized circulatory support technologies revolutionizing the treatment of advanced heart failure, today announced the conclusion of patient enrollment under its "ADVANCE" clinical trial.

HeartWare's ADVANCE clinical trial is an FDA approved IDE study designed to evaluate the HeartWare(R) Ventricular Assist System as a bridge to heart transplantation for patients with end-stage heart failure. The primary endpoint of the trial is survival at 180-days, defined as alive on the originally implanted device or transplanted or explanted for recovery. Secondary endpoints include adverse events such as bleeding and infection, as well as functional status, hospitalization, assessment of neuro-cognitive function and patient quality of life.

"We witnessed a growing enthusiasm from investigators during this study, and we are grateful for their continued support," said HeartWare President and CEO Doug Godshall. "We also had an unexpected acceleration to the completion of the enrollment phase of the trial. During routine discussion with the FDA, we were asked to change the definition of 'enrolled' in our IDE protocol to include patients who were consented to enter the trial, as opposed to those who were consented and met all inclusion and none of the exclusion criteria. With two additional implants scheduled, this modification will result in 30 U.S. clinical sites implanting a total of 140 patients, making ADVANCE the largest bridge-to-transplant pivotal trial to date."

The final implant in ADVANCE is scheduled to occur on February 25, 2010, which, if it goes forward as planned, would result in the final patient reaching the 180-day follow up by the end of August 2010. As a result, it is now anticipated that the submission to the FDA of the PMA will occur in early December rather than late December or early January as previously described.

With completion of the ADVANCE enrollment, HeartWare is seeking approval from the FDA to implant additional bridge-to-transplant patients under a Continued Access Protocol or "CAP" in any U.S. center that implanted a patient under the trial. While there is no guarantee that a CAP will be granted, the FDA has allowed CAPs following full enrollment in prior VAD trials, as it makes the technology available to patients and clinicians while also providing additional safety data for the FDA to evaluate.

Destination Therapy

To advance the clinical development of the HeartWare System, HeartWare has also submitted a protocol to the FDA for a Destination Therapy ("DT") trial in the U.S. The Company is presently actively engaged in discussions with the FDA regarding finalization of the DT protocol. The DT trial is expected to commence in the second quarter of 2010.

About End-Stage Heart Failure

Heart failure is one of the leading causes of death in the developed world. According to the American Heart Association, congestive heart failure (CHF) afflicts approximately 5 million people in the U.S. with approximately 550,000 new cases diagnosed each year. Despite new treatment strategies for patients with end-stage heart failure, the number of patients who die with this disease is of epidemic proportion. Cardiac transplantation is currently the most effective therapy for the treatment of advanced end-stage heart failure, however, its application is limited due to the lack of available donor organs.

Over the last decade, bridging to cardiac transplantation with implantable left ventricular assist devices (LVADs) has gained wider clinical acceptance and LVADs are used to extend life expectancy for patients with end-stage heart failure who might otherwise deteriorate while awaiting a donor heart.

About HeartWare International

HeartWare International develops and manufactures miniaturized implantable heart pumps, or ventricular assist devices, to treat Class IIIb and Class IV patients suffering from advanced heart failure. The HeartWare(R) Ventricular Assist System features the HVAD(TM) pump, a small full-output circulatory support device (up to 10L/min flow) designed to be implanted next to the heart, avoiding the abdominal surgery generally required to implant competing devices. HeartWare has received CE Marking for the HeartWare System in the European Union. The device is currently the subject of a United States clinical trial for a bridge-to-transplant indication.
