"We are honored to announce FDA clearance of the first IND for our next generation personalized immunotherapy, Bria-BRES+," stated Dr. William V. Williams, BriaCell’s President & CEO. "The unique design of Bria-BRES+ offers the potential for a favorable safety profile and meaningful therapeutic benefit in metastatic breast cancer. We look forward to advancing Bria-BRES+ into the clinic as we seek to bring new hope to these patients who have few to no effective treatment options."
As reported in BriaCell’s recent AACR (Free AACR Whitepaper) preclinical poster presentation, Bria-BRES+ demonstrated activation of both adaptive and innate immunity including activation of naïve (resting) T-cells, dendritic cells and natural killer (NK) cells. BriaCell believes this multipronged immune activation may enhance clinical efficacy and help prevent immune escape in patients with metastatic breast cancer.
BriaCell’s Bria-BRES+ builds on its Bria-OTS breast cancer clinical program, where the first patient dosed experienced the sustained complete resolution of a lung metastasis. This 78-year-old woman with advanced metastatic breast cancer and multiple prior treatment failures achieved complete (100%) resolution of a lung metastasis following four doses of Bria-OTS single agent therapy. The complete response of the lesion, initially observed at 2 months, was subsequently confirmed at 4 months, 6 months, and at 11 months. The patient received 17 cycles of Bria-OTS, completed 12 months of the study, and remains in survival follow-up.
