RALEIGH, NC (March 18, 2004) … CLOSURE Medical Corporation (Nasdaq:CLSR), a global leader in biomaterial-based medical devices, announced today that it has received approval from the U. S. Food and Drug Administration (FDA) to initiate a pivotal clinical study to support

U.S. Premarket Approval for its vascular sealant product, the Company’s first product to be used inside the body.  The approval was based on the positive results of a ten-patient pilot study that completed enrollment last December.


The randomized pivotal study will enroll 150 patients, with four- and twelve-week follow-up visits, at approximately 14 medical institutions in the United States and Europe.

Dr. Alan B. Lumsden of Baylor College of Medicine and the Methodist DeBakey Heart Center, The Methodist Hospital, Houston, Texas will act as the principal investigator of the study.  The study will assess the ability of CLOSURE’s vascular sealant to prevent leakage following reconstruction of vascular structures in patients receiving femoral-popliteal bypass or arteriovenous access grafting. 


Daniel A. Pelak, President and CEO, commented, “Attaining FDA approval to initiate the pivotal clinical study is a major milestone for the Company. We are encouraged by the positive results of our pilot study and plan to enroll the first patient in the pivotal study within the next few weeks.  We expect to complete the study by the end of 2004 and if all goes according to plan, we anticipate commencing commercialization of the product outside the U.S., upon receipt of European CE Mark approval, in 2005.” 


The vascular sealant is intended to be used in vascular procedures such as reconstructive grafts and dialysis-access procedures. The product is biodegradable and designed to seal the surfaces of veins, arteries and artificial grafts that can leak after suturing. The formulation is synthetic thereby eliminating the risk of infection transmission and immune response disorders associated with animal-derived or human blood-based products.  In addition, the vascular sealant is transparent, allowing physicians to determine that the seal at the surgical site is complete.
