Theralase Technologies Inc. (TSX-V: TLT) announced the successful results of preclinical studies (in-vitro and in-vivo) demonstrating significant destruction of various brain and colon cancer cell lines. The new proprietary Theralase treatment sharply delayed the tumour progression, when attacked by the Theralase patented light activated Photo Dynamic Compounds (PDCs), signifying a new and broadly promising approach to cancer treatment. When treated with the Theralase PDCs, cancerous mice survived cancer-free for more than 100 days post-treatment, a highly significant milestone.

The scientific data supporting this breakthrough was presented and well received recently at the 9th International Symposium of Photodynamic Therapy and Photodiagnosis in Clinical Practice held in Brixen, Italy. The Theralase presentation was made by Dr. Lothar Lilge, Senior Scientist, Ontario Cancer Institute / Princess Margaret Cancer Centre, University Health Network (UHN) and confirms the significance of the successful research conducted by Theralase in collaboration with UHN scientists, validating this scientific work on the international stage.

Dr. Lothar Lilge stated that, "These preclinical results demonstrate that the Theralase Photo Dynamic Compounds appear to be highly effective (100% cancer cell kill) when used to destroy various cancer cell lines in-vitro; specifically, brain glioma (U-87 and F-98) and in-vivo; specifically, colon cancer (CT-26WT), in the treatment of subcutaneous cancer tumours in Balb/c mice. Mice enrolled in the study, presented with subcutaneous cancerous lesions of approximately 6 mm in size prior to treatment, which is standard for these preclinical models. The statistically significant improvement in survival times make these results even more encouraging, as a number of mice are still alive today living cancer free, 100 days post treatment. Moreover, we believe that tested PDCs may have potential for Type I (oxygen independent) PDT effect; hence, their clinical use would represent a significant gain in cancer therapy."
