VANCOUVER, May 29 /CNW/ - Ondine Biopharma Corporation (TSX: OBP; AIM: OBP), a medical technology company, today announced that it will be presenting clinical and scientific data on Periowave(TM) at a symposium being hosted by the Company on Thursday May 29, 2008 at the Morris J. Wosk Centre for Dialogue in Vancouver, B.C. Dr. Nicolas Loebel, the Company's Chief Technology Officer, will be presenting data on Photodisinfection, Periowave(TM) and results from the Canadian Multi-Centre Trial, a summary of which was initially released on May 7th 2008. Dr. Veronique Benhamou, DDS, Cert. Perio, a Periodontist and Director, Division of Periodontics, and Associate Professor at McGill University, Montreal Quebec, will be presenting case studies and discussing her clinical experiences with Periowave(TM) over the last two years.

In the Multi-Centre Trial, Periowave(TM) treatment resulted in significantly increased clinical attachment level (CAL, p=0.003) and reduced pocket depth (PD, p=0.01) when compared to Scaling & Root Planing (SRP) alone. In addition, 53% more diseased sites demonstrated full resolution of clinical symptoms and converted to a healthy state (Clinical Attachment Level (less than or equal to)3mm, p=0.0004) than was found using SRP alone. These results demonstrate that Periowave(TM) photodisinfection therapy can provide significant clinical benefits in patients with chronic adult periodontitis.

"We are proud to present the details of the Canadian Multi-Centre trial to clinicians and industry participants at this upcoming symposium," stated Carolyn Cross, President and CEO of Ondine Biopharma. "The multi-centre study represents the largest registered clinical trial of photodisinfection ever conducted, and we are pleased with the validation of these outcomes from the in-field experiences of clinicians such as Dr. Benhamou. These results provide further evidence that Periowave(TM) is an effective treatment modality for chronic periodontitis, a disease affecting over half of the adult population."

About The Canadian Multi-Center Trial

The Canadian Multi-Center Trial was a prospective, randomized, examiner-blinded study that included 121 patients and 4,500 defect treatment sites. Fifty-eight patients were included in the Periowave(TM) treatment arm and sixty-three patients were included in the control arm. The study was conducted at the University of Western Ontario, the University of Alberta, the University of Saskatchewan, and at a large private periodontal clinic in Toronto.
