"We are very pleased to report that patient enrollment is on track for expected completion by mid-2025. We anticipate the interim data analysis of the ongoing pivotal Phase 3 study will confirm the effectiveness of the Bria-IMT combination regimen in patients with metastatic breast cancer who failed approved therapies," stated Dr. William V. Williams, BriaCell’s President and CEO.
"Despite multiple approved drugs, breast cancer remains the second-leading cause of cancer death in American women," stated Giuseppe Del Priore, MD, MPH, BriaCell’s Chief Medical Officer. "We are determined to make our novel immunotherapy available to breast cancer patients whose medical needs remain unmet."
35 clinical sites (18 main and 17 satellite) are active and enrolling patients in BriaCell’s pivotal Phase 3 study in metastatic breast cancer. Additional sites are in various stages of start-up.
Interim data will be analyzed once 144 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. Positive results of the pivotal Phase 3 study could result in full approval and marketing authorization for Bria-IMT in MBC patients. Secondary analyses include comparison of the Bria-IMT combination regimen vs Bria-IMT monotherapy. BriaCell recently announced impressive Phase 2 survival data in a similar MBC patient population. The Bria-IMT combination regimen has received FDA Fast Track designation.
