LED Medical Diagnostics Inc.’s Patented VELscope® Vx Device Involved in Phase III Oral Cancer Study

BURNABY, British Columbia – June 10, 2013 – LED Medical Diagnostics Inc. (“LED Medical”, “the Company”), a developer of tissue fluorescence visualization technologies for the medical industry, is pleased to announce that its patented VELscope® Vx oral examination device is currently involved in a Phase III study sponsored by the University of British Columbia in collaboration with the Terry Fox Research Institute and the British Columbia Cancer Agency.

The study, entitled ‘Efficacy of Optically-guided Surgery in the Management of Early-staged Oral Cancer’, postulates the hypothesis that fluorescence visualization (“FV”) guided surgery will increase recurrencefree survival in oral cancer patients. Known internationally as a leading team in the application of tissue fluorescence technology, the University of British Columbia, in collaboration with the Terry Fox Research Institute, has shown that direct fluorescence visualization tools can effectively “identify clinically visible or occult premalignant and malignant lesions that are associated with lesions at risk with high-grade histology and high-risk molecular change. In a recent small scaled retrospective study, we have shown that FV helped surgeons in the operating room to determine the extent of the high-risk FV field surrounding the cancer and resulted in remarkably lower 2-year recurrence rates (0% for FV-guided vs. 25% for those without FV-guided approach). There is a need to design a larger scale prospective, randomized controlled (Phase III) trial to gather strong evidence in proving the surgery approach using this adjunctive tool.”

The study is utilizing LED Medical’s VELscope® Vx Enhanced Oral Assessment System, which centers on a hand-held scope that allows for direct visualization of tissue fluorescence in the oral cavity. “We have begun a longitudinal study to explore the effect of FV to define the surgical margin on the outcome of oral surgery.” The study is currently ongoing.

“We continue to make great strides in the dental vertical for oral health assessment with the VELscope® Vx scope and there are now more than 13,000 dentists in 23 countries using it as part of their standard patient care,” states founder and CEO, Peter Whitehead. “This particular study is unique in that it explores in a multi-centre design not only the efficacy of using the VELscope® Vx for lesion excision but also the resultant effect on long-term recurrence rates. VELscope® technology is the first tissue fluorescence technology to receive FDA and Health Canada clearance to assist surgeons in determining the appropriate surgical margin for the successful excision of oral cancer and pre-cancer. We are confident the study will further support its importance for this application.”
