How Our Immunotherapy Works
We introduce a teaching cell.
Our Bria-IMT® therapeutic cells help the immune system identify
What cancer looks like—safely and clearly.
The immune system wakes up.
Once activated, T-cells learn to seek out and respond
to breast cancer cells with greater accuracy.
Checkpoint inhibitors boost the effect.
When used together, the immune system can stay switched on,
more alert, and more effective.
The goal:
more meaningful time.
A treatment that is focused, intentional, and built to support quality of life every step of the way.

BriaCell’s Patented Immunotherapy
Bria-IMT™ (for MBC)
Bria-IMT™ BriaCell is a Phase 3 lead candidate. is a patented, off-the-shelf, cell-based, targeted immunotherapy that activates the patient’s immune system to specifically kill cancer cells without harming other cells.
Upon achieving impressive survival and clinical benefit results in a Phase 2 study, BriaCell is conducting a pivotal Phase 3 study in metastatic breast cancer, which, if successful, could lead to full approval of Bria-IMT™ in combination with an immune checkpoint inhibitor.
Clinical data includes unprecedented activity in heavily pre-treated MBC patients who have failed antibody-drug conjugate therapy and in patients with metastases to the central nervous system.
BriaCell Therapeutics Corp. (Nasdaq: BCTX, BCTXW; TSX: BCT) is a clinical stage immuno-oncology company that is developing an entirely new class of targeted cellular immunotherapies to transform cancer care

- Provides matched treatment to greater than 99% of patients
- A simple saliva test provides HLA-matched personalized off-the-shelf Bria-OTS™ immunotherapy
- HLA-matched off-the-shelf therapy is faster and less costly than other expensive and complex personalized immunotherapies
- BriaCell received a Small Business Innovation Research (SBIR) award from the National Cancer Institute
- Ongoing collaboration with the NCI
- The Bria-BRES™ Phase 1/2 study is open in breast cancer.
- Bucket trial with additional cancer indications planned
