BriaCell ASCO 2026 Follow-On Press Release (May 22): Final Phase 2 Bria-IMT Median Overall Survival 16.6 Months in Heavily Pretreated Metastatic Breast Cancer With Phase 3 Formulation
BriaCell's formal post-ASCO 2026 press release Friday morning specified the headline number from yesterday's abstract release. Final Phase 2 median overall survival with Bria-IMT plus checkpoint inhibitor reached 16.6 months in heavily pretreated metastatic breast cancer patients using the Phase 3 formulation — a substantial improvement over historical post-ADC, post-CPI, post-CDK4/6-failure populations where median OS typically runs 8-10 months. The release also specified positive quality-of-life data from the ongoing Phase 3 study and biomarker analyses confirming the predictors of anti-cancer response observed in Phase 2 carry forward into the Phase 3 cohort. The three poster presentations plus three publication-only abstracts at ASCO 2026 (May 29-June 2) will detail 12- and 24-month survival, treatment tolerability, and circulating-tumor-cell biomarker work. The 16.6-month median OS sets the bar BriaCell needs to clear or beat in the ongoing Phase 3 to support its accelerated approval ambitions.
