Sona Presents Additional Preclinical Data Demonstrating Repeated Ability Of Its Cancer Therapy To Inhibit Tumor Growth In Colorectal Cancer Model
Halifax, Nova Scotia – (Newsfile Corp. – March 19, 2025) – Sona Nanotech Inc. (CSE: SONA) (OTCQB: SNANF) (the “Company”, “Sona”) is pleased to provide updated data confirming efficacy of its Targeted Hyperthermia Therapy (“THT”) cancer treatment in an immunotherapy resistant cancer. In this follow-up data to the previously released preliminary study (see press release dated December 11, 2024), again using an industry-standard, immunotherapy resistant, CT-26 colon cancer model, Sona’s THT cancer treatment was 100% effective in activating a strong, effective immune system response. In these experiments, animals treated with a PD-1 checkpoint inhibitor, a standard of care immunotherapy, experienced no benefit with tumors growing similarly to tumors in the control group of untreated animals. However, in a new, second cohort of eight animals first treated with Sona’s THT and then treated with a PD-1 inhibitor, 100% of animals responded demonstrating near complete arrest in tumor growth in the majority of animals as highlighted by the dashed green line in Figure 1, below.
