Theralase Compound Highly Effective in Destroying Bladder Cancer Tumour Cells
Toronto, Ontario –November 12, 2012 -- Theralase Technologies Inc. (TSX-V: TLT) Photo Dynamic
Therapy (PDT) Division, announced today study results proving that its patented Photo Dynamic
Compounds (PDCs) were significantly more effective in destroying a human urinary bladder carcinoma
cell line than a FDA approved photosensitizer, aminolevulinic acid (ALA).
Dr. Arkady Mandel, Chief Scientific Officer of Theralase stated, “Commercialization of any new anti-
cancer medicine depends upon the safe and effective destruction of all cancerous tumours, while
upholding the patient’s quality of life. We are excited that our leading compound effectively destroyed
a human urinary bladder carcinoma cell line (HT-1376) when activated by our proprietary light system.
To validate our initial success, we evaluated the efficacy of the Theralase PDC in comparison with
aminolevulinic acid (ALA). The results indicated that the Theralase PDC was effectively destroying
bladder cancer cells at much lower concentrations than ALA (1/1000th of the dose).”
Dr. Lothar Lilge, Professor and Senior Scientist, Ontario Cancer Institute, Princess Margaret Cancer
Centre, University Health Network stated, “In my lab, the Theralase PDCs have shown remarkable
efficacy and robustness in the destruction of various cancer cell lines, such as: colon, brain, breast and
now bladder cancer. This research potentially offers a new opportunity for individualized cancer
therapy across various invasive tumours.”
Roger Dumoulin-White, President and CEO, Theralase Inc. stated, “Based upon our recent success, we
have now reconfirmed that bladder cancer is our lead cancer target for our lead PDC compound. Our
research confirms what we had already suspected; our PDC technology is lethal to human urinary
bladder carcinoma cells. Given that our technology can deliver effective results at significantly lower
doses than ALA, this would suggest a superior safety and cost effectiveness for our lead compound, as
compared to ALA. We are confident that as we complete our preclinical research and prepare for
human trials in 2013, we will demonstrate to the medical community that we possess a highly
effective, safe and efficient alternative treatment option to current bladder cancer patients.”
Bladder cancer is the fifth most common cancer in the North America; the fourth most common among
men and eighth most common in women. In the United States 73,000 new bladder cancer cases and
15,000 deaths are reported annually. With a recurrence rate of nearly 80%, bladder cancer is the most
expensive cancer to treat on a per patient basis. The high recurrence rate severely affects the quality of
life of patients and also the total cost of treatment, which in the United States exceeds $2.9 billion in
direct treatment related costs annually.
In other related news, Sun Pharmaceutical Industries (NSE: SUNPHARMA, BSE: 524715), with a market
value of $USD 13.3 billion, announced on November 8, 2012, that it signed a definitive agreement to
acquire Dusa Pharaceuticals Inc. (DUSA) for $8 per share for a total cash consideration of $USD 230
million. DUSA is a dermatology company focused on developing and marketing its FDA approved
Levulan photodynamic therapy platform (active ingredient of Levulan is ALA), for actinic keratosis of
the face or scalp (dry, scaly patches on the skin that can lead to skin cancer).
