Raleigh, NC, June 8, 1999-- CLOSURE Medical Corporation (Nasdaq: CLSR), a medical tissue cohesive products company, today announced its filing of a 510(k) with the FDA, seeking marketing clearance for its SOOTHE-N-SEAL™ canker sore relief. The filing is based in part on the findings of a sponsored 155-patient multi-center clinical study conducted at Brigham & Women's Hospital, the School of Dentistry at UNC-Chapel Hill, and the Forsyth Dental Center.

In the multi-center study, SOOTHE-N-SEAL™ canker sore relief was found to provide immediate and long-lasting pain relief. In addition, SOOTHE-N-SEAL™ canker sore relief provided a protective barrier that reduced the pain associated with the irritation of eating and drinking.

"Based upon primary market research we believe that there are about 40 million households within the U.S. in which one or more members have suffered from oral ulcers within the past 6 months," said Mr. Robert V. Toni, President and CEO of CLOSURE Medical Corporation. "SOOTHE-N-SEAL™ canker sore relief may provide immediate and long-lasting pain relief from the discomfort associated with these oral ulcers."

CLOSURE Medical Corporation is currently seeking a well-positioned OTC consumer marketing partner for SOOTHE-N-SEAL™ canker sore relief. SOOTHE-N-SEAL™ canker sore relief is the first step in developing what CLOSURE Medical Corporation believes to be a significant platform of OTC consumer products.

CLOSURE Medical Corporation, headquartered in Raleigh, North Carolina, develops, manufactures and commercializes medical tissue cohesive products based on its proprietary cyanoacrylate technology.
