Second Quarter Highlights

During its second quarter of 2013, the Company achieved the following:

·                  Continued clinical enrollment with the ReZolve2 scaffold, which is being implanted in up to 125 patients at locations in Australia, Brazil, Germany, New Zealand, Poland, and Slovenia and is designed to provide the data needed for the CE Marking application anticipated to be made in 2014;

·                  Continued implementation of plans to provide commercial-scale manufacturing at the Company’s facility in San Diego, California;

·                  Appointed the Managing Director International, who will plan the Company’s sales and marketing activities for commercialization in international markets;

·                  Continued development of additional scaffold sizes, which are designed to allow multiple product sizes to be available for sale following CE Marking;

·                  Continued 12-month follow-up on patients in the RESTORE clinical study who were implanted with the ReZolve scaffold between December 2011 and July 2012 and released 12-month data on a subset of the ReZolve patients at the Paris Course on Revascularization (“PCR”) in late May.

About REVA

REVA is a development stage medical device company incorporated in Delaware, USA, that is focused on the development and eventual commercialization of its proprietary bioresorbable stent products. The ReZolve® product family, which is in a clinical study phase, combines REVA’s proprietary stent design with a proprietary polymer that is metabolized and cleared from the body. REVA’s anticipated commercial product, the ReZolve2 scaffold, is designed to offer full x-ray visibility, clinically relevant sizing, and a controlled and safe resorption rate. In addition, by early encapsulation of the stent in the artery tissue coupled with the loss of scaffold structure over time, the ReZolve2 scaffold may reduce the incidence of late forming blood clots or otherwise reduce long-term disease progression, potential benefits of bioresorbable scaffolds that have yet to be proven. REVA will require clinical results and regulatory approval before it can begin selling the ReZolve2 scaffold.
