Sona Nanotech Announces Director Retirement

Sona Nanotech Inc. (CSE: SONA) (OTCQB: SNANF) (the "Company" or "Sona") announces further results from the triple negative breast cancer murine model portion of its current research study at Dalhousie University (the "Study") which confirms that the previously reported tumor volume reduction was due to activation of a tumor specific systemic immune response. These data relate to the follow-up biomarker analysis performed on the previously reported cohort of animals that showed a statistically significant synergistic effect in the shrinking of both treated and untreated tumors in animals bearing multiple tumors after treatment with the combination of Sona's targeted hyperthermia therapy ("THT") and interleukin-2 ("IL-2"), an immunotherapy agent widely used to treat human cancer patients.

Sona Nanotech Inc. (CSE: SONA) (OTCQB: SNANF) (the "Company" or "Sona") is pleased to announce further positive interim results from its study with The Giacomantonio Immuno-Oncology Research Group at Dalhousie University (the "Study"). The Company was provided with data from the Study that indicates the response in a pre-clinical triple negative breast cancer model treated with the combination of Sona's targeted hyperthermia therapy ("THT") and interleukin-2 ("IL-2"), a standard immunotherapy, is statistically significantly superior to results observed from treatment with either agent individually or the control group. This second phase of the Study has documented that, in a cohort of six animals, 66 of treated triple negative breast cancer, the most aggressive and therapy resistant form, mouse tumors bearing gold nanorods and IL-2 responded to the combination therapy, resulting in a flattening of the tumor growth curves, as shown in the below graph. The generation of hyperthermia involved exposing tumors previously injected intratumorally with Sona's gold nanorods and IL-2 to a single dose of near infrared light.

Sona Nanotech Inc. (CSE: SONA) (OTCQB: SNANF) (the "Company" or "Sona") announces that it has been approved for funding totaling approximately $40,000 to support the development of its intellectual property portfolio.

The Company is receiving advisory services and up to $24,894 in funding from the National Research Council of Canada Industrial Research Assistance Program ("NRC IRAP") IP Assist program to support the development of an intellectual property strategy for Sona's proprietary gold nanorods for novel targeted drug delivery concepts with a view to securing new patents.

Sona Nanotech Inc. (CSE: SONA) (OTCQB: SNANF) (the "Company" or "Sona") announces positive interim results from its study with The Giacomantonio Immuno-Oncology Research Group at Dalhousie University (the "Study"). An update received by the Company indicates that all tumors treated within the Study to date with a single Targeted Hyperthermia Therapy ("THT") treatment shrunk within the first 24 hours, with an average reduction in size of 80% compared to matched controls.

Study Principal Investigator, Dr. Carman Giacomantonio, comments, "Our initial assessment documented that in cohorts of seven animals, 7/7 of treated triple negative breast cancer mouse tumors bearing gold nanorods responded with an average reduction in tumor volume of 80% following a single treatment with near infrared light in comparison with untreated 'control' tumors. Interestingly, in all cases we observed responses (tumor shrinkage) in distant, untreated tumors supporting the hypothesis that our observations are consistent with systemic immunogenic responses. This observation will be a significant focus of our research going forward. While we are encouraged by these initial results, there is still significant work to be completed. The studies are designed to enable and identify statistical significance which will be achieved with the completion of the full Study."

Sona Nanotech Inc. (CSE: SONA), (OTCQB: SNANF) (the "Company" or "Sona") announces that it has submitted a provisional patent application with the United States Patent and Trademark Office (USPTO), for its proprietary photothermal light device, entitled, "ENDOSCOPE WITH EMR OPTICAL FIBER AND THERMAL SENSOR FOR PHOTOTHERMAL THERAPY".

A prototype of Sona's medical laser was engineered in conjunction with Minnetronix Medical to apply non-thermal, 860 nanometer wavelength high intensity infrared laser light. The device has been designed for use with Sona's patented/patent pending biocompatible gold nanorods which efficiently convert the non-thermal light energy into heat. The device has controls to regulate the intensity and duration of the light exposure and to permit a user to monitor and control the temperature generated in tissue. The device is currently being used for the Company's ongoing pre-clinical efficacy study of its Targeted Hyperthermia Therapy cancer treatment at Dalhousie University.
