BriaCell’s Phase 3 study now has 69 active clinical sites across 15 states, including Mayo Clinic, DHR Health Oncology Institute, Hematology Oncology Associates of Fredericksburg, Los Angeles Cancer Network, Manhattan Hematology/Oncology Associates, New York Cancer & Blood Specialists, Northwestern University, Smilow Cancer Hospital at Yale New Haven, Sylvester Comprehensive Cancer Center, Texas Oncology-Baylor Charles A. Sammons Cancer Center, and University of Arizona.

"We are very excited to be working with renowned clinical experts at a leading cancer center like Mayo Clinic, who also participated in BriaCell’s Phase 2 study," stated Dr. Giuseppe Del Priore, BriaCell’s Chief Medical Officer. "We strongly believe that our novel immunotherapy has the potential to transform cancer care for patients and their families."

BriaCell’s pivotal Phase 3 clinical study is evaluating BriaCell’s lead clinical candidate, Bria-IMT, plus immune check point inhibitor (CPI) versus physician’s choice in advanced metastatic breast cancer (Bria-ABC).

Interim data will be analyzed once 144 patient events (deaths) occur, comparing the overall survival (OS) in patients treated with the Bria-IMT combination regimen versus those treated with physician’s choice as the primary endpoint. BriaCell recently (ASCO 2025) announced positive Phase 2 survival data in a similar MBC patient population treated with the same Bria-IMT combination regimen . The Bria-IMT combination regimen has received FDA Fast Track designation.
