Business Editors

LAVAL, Quebec--(BUSINESS WIRE)--Sept. 25, 2000

BIOSYNTECH Inc. (OTCBB: BSYI) today announced it has successfully completed pre-clinical safety and evaluation studies of one of its lead products, BST-GEL(TM), an injectable, thermo-sensitive hydrogel for therapeutics delivery.

The studies showed BST-GEL(TM) to have no systemic toxic effects at dose levels up to 100 times greater than would be used in clinical therapy. The pre-clinical acute and sub-chronic repeat-dose subcutaneous animal toxicology trials were performed at ITR Laboratories Canada Inc., in full compliance with the Good Laboratory Practice (GLP) Regulations of the United States Food and Drug Administration.

"The successful completion of these pre-clinical studies is very encouraging," said Dr. Ajay Gupta, Vice-President of Business and Product Development. "BST-GEL(TM) is at the core of the development of a wide array of innovative biomedical products in many different therapeutic areas."

The BST-GEL(TM) was also found to localize as a deposit at the site of administration by injection, without causing any inflammatory response or other obvious indications of systemic effects, such as overt clinical signs, mortality, and loss of appetite or of body weight. The terminal investigations in the sub-chronic studies showed no significant changes in the organ weights and gross pathology findings were limited to localized deposits of BST-GEL(TM) at injection sites without evidence of encapsulation or other adverse biological response.

"We are very pleased with the safety profile emerging from these pre-clinical evaluations of BST-GEL(TM)," commented Marie-Claire Pilon, recently appointed CEO of BIOSYNTECH. "With these results, we will be moving forward aggressively, as planned, to the next phase of clinical assessment."
