Carrington Laboratories, Inc. And Brookwood Pharmaceuticals, Inc. Expand GelSite(R) Drug Delivery Technology Development

IRVING, Texas, July 20 /PRNewswire-FirstCall/ -- Carrington Laboratories, Inc. (Nasdaq: CARN - News) announced today that its subsidiary, DelSite Biotechnologies, Inc., formed a joint development initiative with Brookwood Pharmaceuticals, Inc. The goal of this effort is to carry out an expanded evaluation of GelSite®, a DelSite patented drug-delivery technology, as a matrix for injectable applications and for selected classes of drugs.

GelSite® is a naturally derived, biocompatible, resorbable biopolymer that can be used to deliver biopharmaceuticals. This technology has the potential to protect and deliver peptides and proteins effectively while reducing the frequency of drug administration. Fewer injections will improve patient compliance, safety and efficacy. Injectable, controlled-release applications for peptides and proteins are in the multibillion-dollar drug delivery market.

"The team at DelSite has been making great strides with the GelSite® technology, particularly in the vaccine area. We are excited to be collaborating with them -- combining our teams of polymer and drug delivery experts -- to broadly evaluate parenteral applications," said Dr. Arthur J. Tipton, President and CEO.

Under this new expanded joint development initiative, the evaluation of GelSite® technology will be managed by a team of experts from Brookwood Pharmaceuticals and DelSite. "Brookwood Pharmaceuticals is internationally recognized for its pioneering contributions in the drug delivery field, particularly for the development of long-acting parenteral formulations, including injectable microparticles and injectable solid implants," said Dr. Carlton E. Turner, president and CEO of Carrington.

Dr. Thomas R. Tice, Executive Vice President and CSO, added, "I have been interested in this technology for some time. We have previously worked in specified areas with DelSite, but now with this broader collaboration, I think our teams will likely develop a range of interesting applications."
