Periowave(TM) Gum Disease Therapy: Positive Results From Meta-analysis

    VANCOUVER, Sept. 10 /CNW/ - Ondine Biopharma Corporation (TSX: OBP; AIM:
OBP), a medical technology company, today announced results of a meta-analysis
(statistical review of pooled clinical trial data) of its Periowave(TM)
Photodynamic Disinfection System in the treatment of gum disease. The analysis
covered three trials enrolling a total of 126 patients at four clinical
centers over the past two years. Among other data, the meta-analysis found
that Periowave(TM) used in a re-treatment protocol (six weeks apart) produced
2.3 times more clinically relevant (2+ mm) pocket depth reductions than the
gold standard of scaling and root planing (SRP) alone (p(less than)0.0001).
    Studies included a trial at an independent clinic in Everett, WA where
clinically and statistically significant endpoints were achieved; a two-center
study conducted by Loma Linda University where clinically and statistically
significant endpoints were achieved and a study conducted by University of
British Columbia where it was found that the protocol allowed for too few
patients meeting inclusion criteria to be recruited. Patients who did meet
inclusion criteria were included in the meta-analysis. No treatment-related
adverse events were reported at any center. Endpoints included pocket depth,
clinical attachment level and bleeding on probing.
    The meta-analysis results supported prior findings, demonstrating that
Periowave(TM) was safe and effective in producing statistically and clinically
relevant improvements in periodontal pocket depth compared to scaling and root
planing. Periowave(TM) produced more than double the number of large (2+ mm)
pocket depth reductions than scaling and root planing alone (p(less
than)0.0001). The results were achieved across studies that incorporated
different ethnic groups, smoking status, treatment protocols and laser power
    "These positive meta-analysis results will be integrated into our FDA
submission," said Carolyn Cross, CEO and President of Ondine Biopharma.
"Periowave(TM) has now been successfully tested in standard recall patients,
patients with advanced disease, patients undergoing re-treatment protocols and
patients with recurrent disease. In addition, Periowave(TM) has already been
extensively deployed in the dental clinic following its approval in Canada and
the European Union, with several thousand patients treated to date.
Periowave(TM) has proven to be a safe and effective adjunct to SRP in many
patients, irrespective of demographics, smoking status or nature of the
