BriaCell Reports 11-Month Complete Resolution of Lung Metastasis in Metastatic Breast Cancer Patient
PHILADELPHIA and VANCOUVER, British Columbia, Jan. 13, 2026 (GLOBE NEWSWIRE) -- BriaCell Therapeutics Corp. (Nasdaq: BCTX, BCTXW, BCTXZ) (TSX: BCT), a clinical-stage biotechnology firm, has reported a significant milestone in its Bria-OTS program. The personalized immunotherapy has achieved the sustained complete resolution of a lung metastasis in a patient suffering from metastatic breast cancer (MBC). This breakthrough provides hope for patients with limited treatment options.
Details of the Clinical Study
The patient, a 78-year-old woman diagnosed with advanced metastatic breast cancer and multiple prior treatment failures, was enrolled in the Bria-OTS Phase 1/2a clinical study. After receiving four doses of Bria-OTS monotherapy, she achieved a complete (100%) resolution of a lung metastasis. This complete response was confirmed over time:
- Initial observation at 2 months
- Confirmed at 4 months
- Verified at 6 months
- Persisted through to 11 months
The patient has undergone 17 cycles of Bria-OTS and completed 12 months in the study, now continuing in survival follow-up.
Study Advancement and Future Plans
The Phase 1 portion focusing on dose escalation is now complete, and the study progresses into Phase 2a. This phase will explore the effects of combining Bria-OTS with an immune checkpoint inhibitor. Dr. Neal S. Chawla, Director at the Sarcoma Oncology Center and Principal Investigator of the Bria-OTS study, remarked on the significance of the observed clinical response: “The sustained clinical response in this late-stage MBC patient, who previously progressed through multiple treatments, is remarkable.”
Dr. William V. Williams, BriaCell’s President and CEO, added, “These clinical findings reinforce our confidence in the therapeutic potential and safety of the Bria-OTS platform.” The company remains dedicated to advancing their therapeutic approach aimed at improving outcomes for patients facing metastatic breast cancer.
