BioSyntech Receives Approval for Canadian BST-Cargel'R' Pivotal Clinical Trial

LAVAL, QUEBEC--(CCNMatthews - Nov. 16, 2005) - BioSyntech, Inc. ("BioSyntech" or "the Company") (TSX VENTURE:BSY) announced today that it has received approval from Health Canada, Therapeutic Products Directorate, Medical Devices Bureau, to begin its pivotal clinical trial for BST-CarGel®. The Company expects the data from this trial to support Canadian and European regulatory approval of BST-CarGel®, a medical device for cartilage repair designed to regenerate cartilage in a process called In Situ ChondroInduction (ICI). Subject enrolment and surgery will commence immediately and treatment will proceed according to surgical facility availability.

"Historically, treatment of cartilage damage has been a problematic area for orthopaedics due to a continued lack of technological breakthroughs. This has left many patients without viable options, and many of these patients may eventually require total knee replacement," said Mr. Claude LeDuc, President and CEO of BioSyntech. "We believe that BST-CarGel® is a potential solution to this growing need to repair cartilage damage and, to that end, have initiated a controlled and randomized clinical trial with a strong scientific design. Our trial data will not only support Canadian and European approval, but may be instrumental in gaining regulatory approval in the United States."

The BST-CarGel® trial will be a randomized, comparative study of the treatment of focal cartilage lesions located on the medial femoral condyle in 80 subjects from 18 to 50 years of age. Treatment with BST-CarGel® applied to a microfractured cartilage lesion varying from 4 to 10 cm2 will be compared to microfracture alone applied to similar lesions. Subjects will be randomized between the BST-CarGel® group and the microfracture group, and further stratified to their lesion type, either characterized as acute (i.e. traumatic) or chronic (i.e. degenerative). Following surgery, all subjects will follow the same 12 week physiotherapy regimen, which utilizes assisted passive motion and common strengthening exercises, and calls for a 6 week period of non-weightbearing.

The primary endpoint for this trial will be cartilage repair at 12 months, defined as a composite of the quantity and quality of the repair tissue measured through validated, advanced magnetic resonance imaging (MRI). Other major endpoints at 12 months include knee-related pain, stiffness and function, as well as overall quality of life assessed through subject-filled questionnaires.

For the MRI component of this trial, the Company has retained Rochester, NY-based VirtualScopics, LLC, the premier provider of innovative imaging solutions utilizing biomarkers for product development and clinical trials. VirtualScopics has extensive clinical experience in musculoskeletal radiology using patented analytical techniques which detect, measure and analyze specific biological structures from MR imaging. This expertise coincides well with this trial's cartilage repair objective. These scans, which include both screening of potential subjects as well as 12 month endpoint assessments, will be carried out at one pre-qualified MRI clinic at each site, followed by blinded data analysis at VirtualScopics.

As previously announced, critical study initiation steps, monitoring and reporting will be managed by Cato Research Ltd., a contract research organization (CRO) who will ensure that the protocol and the study conduct adhere to regulatory requirements to ensure that the outcomes are accepted by regulatory agencies.

Sites involved in this trial are located in Winnipeg, Halifax, Calgary, Montreal and Toronto. BioSyntech will add sites, if needed, according to enrolment rates.

About BST-CarGel®

BST-CarGel® is a promising new therapeutic approach for repair of localized cartilage lesions. Applied during minimally-invasive surgery, it acts in situ as a 3-dimensional scaffold and may guide the repair of the damaged cartilage.
