DelSite Presents New Data on GelSite® Nasal Powder Delivery System at Controlled Release Society Meeting

GelSite® Polymer Has a Distinct Chemical and Biological Function Uniquely Suited to Meet the Challenges Faced in a Pandemic Flu

IRVING, Texas, July 26 // -- Carrington Laboratories, Inc. (NASDAQ:CARN) today announced that Dr. Paul Stroud, Director of Polymer Research and Development at DelSite Biotechnologies, Inc., Carrington's wholly-owned subsidiary, presented the latest findings on the GelSite® nasal powder delivery system for proteins and peptides at the 33rd Annual Meeting of the Controlled Release Society held in Vienna, Austria.

The delivery system's key component is the GelSite® polymer, which provides gelling and mucoadhesion properties allowing for prolonged nasal residence time and sustained release of potential peptide/protein therapeutics to the circulation and central nervous system. Data suggest that this delivery system can be formulated to allow for interactions between the polymer and peptides/proteins for enhanced stability, which adds an additional means of controlled release in developing formulations for optimal delivery of vaccines and therapeutics.

Carlton E. Turner, CEO of Carrington and DelSite, said, "Dr. Stroud's work on the GelSite® polymer nasal powder drug delivery platform represents a novel and efficient approach for nasal drug delivery. It is not only suitable for drugs for local actions, but also those with systemic effects. In addition, the platform can possibly provide rapid absorption and onset of pharmacological activity, avoidance of some liver metabolism, an easy and fast route of administration, and the possibility of an efficient pathway to deliver therapeutics across the brain barrier. These factors make this delivery platform rather fascinating."

Turner continued, "The GelSite polymer is also highly suited for injectable administration. The value of stabilization and controlled delivery of therapeutics was the driving force for the recent technology development agreement with Brookwood Pharmaceuticals for development of injectable applications using GelSite® polymer."
