Raleigh, NC, March 28, 2000 -- CLOSURE Medical Corporation (Nasdaq: CLSR), a medical tissue adhesive products company, today announced that it is initiating a clinical study for LIQUIDERM™ Liquid Healing Bandage for the treatment of minor cuts and abrasions. Results from the clinical study will be used in an anticipated 510(k) submission to the FDA.

LIQUIDERM™ Liquid Healing Bandage would compete in the over-the-counter adhesive bandage category, which exceeds $800 million in worldwide sales.

"The start of the definitive clinical trial for LIQUIDERM™ Liquid Healing Bandage represents a major step in the development of a transformational innovation for Closure Medical", said Robert V. Toni, President and CEO. "We believe our unique adhesive technology could fulfill needs not being met by any adhesive bandage currently on the market."

Preliminary animal studies have shown that LIQUIDERM™ Liquid Healing Bandage creates a moist wound-healing environment and provides a barrier to infection for minor cuts and abrasions. "A moist wound healing environment promotes improved healing of minor cuts and abrasions," said Dr. William Eaglstein, professor and chairman of the Department of Dermatology and Cutaneous Surgery at the University of Miami School of Medicine.

Mr. Toni continued, "LIQUIDERM™ Liquid Healing Bandage is unlike existing adhesive bandages. It creates a long lasting healing environment that requires only one application. It conforms exactly to any wound size providing superior protection from dirt and germs. Additionally, the flexible film stays on bending and moving parts of the body even in water."

The 160 patient multi-center study will be conducted at the University of Miami under the direction of Dr. Eaglstein, the Orlando Regional Healthcare System by Dr. Philip Giordano, the Palm Beach Research Center under Dr. Barry Miskin, and the Skin Study Center by Dr. James Leyden.
