PHILADELPHIA and VANCOUVER, British Columbia, May 30, 2024 (GLOBE NEWSWIRE) -- BriaCell Therapeutics Corp. (NASDAQ: BCTX, BCTXW) (TSX: BCT) (“BriaCell” or the “Company”), a clinical-stage biotechnology company that develops novel immunotherapies to transform cancer care, announces initiation of a first-in-human, Phase 1/2 study evaluating safety and efficacy of Bria-OTS™, BriaCell’s personalized off-the-shelf next generation immunotherapy, as monotherapy and in combination with PD-1 inhibitor tislelizumab, in advanced metastatic breast cancer.

“Advancing Bria-OTS™ as our second novel immunotherapy candidate into the clinic is a significant milestone for BriaCell. We believe personalization through our Bria-OTS™ immunotherapy platform will produce more potent and long-lasting responses than previously observed, with potential synergistic effects with the immune check point inhibitor,” stated Dr. William V. Williams, BriaCell’s President & CEO. “We are grateful to our scientific and clinical teams for the successful completion of the Institutional Review Board (IRB), Clinical Trial Site Agreement (CTA), and obtaining FDA authorization for the Investigational New Drug (IND) filings, as well as to our investors and collaborators for their support in bringing Bria-OTS™ one step closer to cancer patients.”

Giuseppe Del Priore, MD, MPH, BriaCell’s Chief Medical Officer stated, “The off-the-shelf nature of our treatment will allow the patients to be treated rapidly – which can be life changing for advanced metastatic breast cancer patients. Additionally, we expect the preferred safety profile of our personalized immunotherapy, Bria-OTS™, to improve the quality of life and add months and even years to the lives of these heavily pretreated patients, a distinctive combination of benefits in late-stage cancer care.”
