Theralase Discovers Cannabinoid Increases Efficacy of Patented Anti-Cancer Technology in Destruction of Brain Cancer

Toronto, Ontario (FSCwire) - Theralase Technologies Inc. (“Theralase®” or the “Company”) (TSXV: TLT) (OTCQX: TLTFF), a clinical stage pharmaceutical company dedicated to the research and development of light activated Photo Dynamic Compounds (“PDCs”) and their associated drug formulations to safely and effectively destroy various cancers, announced the filing of a US patent application detailing the discovery of a significant increase in the destruction of cancer cells, when Theralase’s patented anti-cancer technology is combined with cannabinoids.


In preclinical experiments, Theralase scientific researchers combined a specific cannabinoid with their patented anti-cancer Photo Dynamic Therapy (“PDT”) technology to produce an unexpected synergistic effect in the destruction of rat glioma brain cancer cells (“RG2”).


In the study, RG2 brain cancer cells were preconditioned, in-vitro, with a specific cannabinoid and then subjected to Theralase’s anti-cancer technology. The researchers discovered that the efficacy of this combined treatment increased 250%, compared to treatment with Theralase’s anti-cancer technology or the specific cannabinoid alone. 


Mark Roufaiel, Ph.D., research scientist at Theralase stated, “The latest data demonstrates that the use of a selected and non-toxic cannabinoid is able to increase the killing effect of Theralase’s anti-cancer PDT in a synergistic manner, leading to an effect greater than the sum of their individual effects. These results strongly suggest that a specific cannabinoid could be used to increase tumour destruction and improve therapeutic outcomes.”


Arkady Mandel, M.D., Ph.D., D.Sc., Interim Chief Executive Officer and Chief Scientific Officer at Theralase stated that, “The anti-inflammatory and anti-proliferative properties of cannabinoids may provide additional benefits to our patented anti-cancer technology.  Our scientific research team undertook experiments to combine PDT and a cannabinoid to assess if there were any perceived benefits. In order to observe the effects of the specific cannabinoid, the PDT drug and light doses were reduced and hence the efficacy of the anti-cancer technology at these levels. Lo and behold, we discovered that the combination of these two technologies produced a greater than anticipated synergistic effect.”


Dr. Mandel went on to say, “We had expected the pairing of the two technologies to produce an additive effect, that is, the efficacy of one technology would “add” to the efficacy of the other technology, as in a one plus one equals two scenario. Instead, we were pleasantly surprised to discover that these two technologies, when used in combination, produced a much higher kill rate than expected, delivering results where one plus one now equals three and one half.”


The graph below depicts the preclinical results obtained:


1) Control - no treatment, no effect

2) Theralase® PDT alone (10%)

3) Specific cannabinoid alone (10%)

4) Hypothetical expected additive effect of the specific cannabinoid + PDT (20%)

5) Actual observed synergistic effect of the specific cannabinoid, when combined with Theralase’s PDT (35%)

Dr. Mandel stated, “I am very pleased with these preclinical results and if we are able to translate this technology successfully to humans, it strongly suggests that specific cannabinoids could be used to increase the efficacy of Theralase’s anti-cancer PDT technology in the destruction of deadly cancers, such as Glioblastoma Multiforme (“GBM”) brain cancer. The initial results reported are the first of a set of experiments planned by our scientific research team in the field of combining cannabinoids with Theralase’s PDT technology and also our anti-cancer vaccine, RuVaCare, in the destruction of human cancers. We believe this research will provide a strong foundation for a “first-in-man” clinical study, where the Company’s patented anti-cancer technology and / or anti-cancer vaccine will be combined with cannabinoid(s) in the treatment of cancer.


Dr. Mandel concluded by saying that, “This latest preclinical research lays the groundwork for the Company to actively seek strategic partnerships in the co-development of this combined technology for the treatment of specific human cancers, such as GBM. The Company plans to explore these avenues in the immediate future, with the hopes of securing a joint venture with a company interested in the development of this combination technology, such as a Canadian cannabis producer.”
