Initial Clinical Results for Fantom Scaffold

San Diego, California and Sydney, Australia (Friday, 22 May 2015, AEST) — REVA Medical, Inc. (ASX: RVA) (“REVA” or the “Company”) released initial clinical data on a subset of patients treated with the FantomTM sirolimus-eluting bioresorbable scaffold at the Paris Course on Revascularization (“EuroPCR”). Reporting on the results was Dr. Alexandre Abizaid, Director of Invasive Cardiology at the Institute Dante Pazzanese of Cardiology, in Sao Paulo, Brazil, and co-principle investigator for the Fantom clinical trial program. Dr. Abizaid presented during the Cardiovascular Innovations Pipeline session on Thursday, May 21, 2015, CEST.

The FANTOM I pilot clinical trial, which enrolled patients with the Fantom scaffold at two clinical sites in Brazil and Poland, was designed to provide early clinical data on the device. In these patients acute performance was demonstrated with 100% technical and procedural success and no reported Major Adverse Cardiac Events (“MACE”) to date, with no incidence of ischemic target lesion revascularization (“TLR”), myocardial infarction (“heart attack”), or stent thrombosis.

“We are pleased with the early clinical results we are seeing with the Fantom scaffold,” stated Jeff Anderson, REVA’s Senior Vice President of Clinical and Regulatory Affairs. “In the patients that have completed their four-month angiographic assessment we have observed that the scaffold is performing well and the treated vessels remain widely patent.”

REVA is currently enrolling patients in the FANTOM II trial, which is designed to provide the necessary data for a European CE Mark application of Fantom. Initial data from the FANTOM II trial, along with continued follow-up data from patients enrolled in the pilot clinical trial, is planned to be presented at the Transcatheter Cardiovascular Therapeutics (“TCT”) Conference this year, which will be held in October in San Francisco, California.

The presentation materials delivered at the conference are attached hereto. A copy of these materials are also being filed with the U.S. Securities and Exchange Commission and posted under the Investor Relations section of REVA’s website at www.revamedical.com.

About REVA

REVA is a development stage medical device company located in San Diego, California, USA, that is focused on the development, testing, and eventual commercialization of its proprietary bioresorbable stents, which are called “scaffolds” because of their temporary nature. The Company’s scaffolds are currently in clinical studies and have been developed as an alternative to metal stents, which are small tube-like devices permanently implanted into an artery to treat coronary artery disease. Scaffolds provide restoration of blood flow, support the artery through the healing process, then disappear (or “resorb”) from the body over a period of time. This resorption allows the return of natural movement and function of the artery, a result not attainable with permanent metal stents. The Company’s initial intended commercial product, the FantomTM scaffold, has been designed to offer an ideal balance of thinness and strength, and distinct ease-of-use features including complete scaffold visibility under x-ray, expansion with one continuous inflation, and no procedural time limitations. REVA will require successful clinical trial results and regulatory approval before it can commercialize Fantom or any other products.
