BriaCell ASCO 2026 Final Phase 2 Bria-IMT Survival Data (May 21): Cell-Immunotherapy + Checkpoint Inhibitor in Heavily Pretreated Metastatic Breast Cancer
BriaCell released final randomized Phase 2 Bria-IMT survival and quality-of-life data at ASCO 2026 alongside biomarker analyses from the ongoing Phase 3 study. Bria-IMT — a whole-cell allogeneic peptide-and-cell immunotherapy combined with checkpoint inhibitor — has been studied in heavily pretreated metastatic breast cancer patients who have failed antibody-drug conjugate, checkpoint, and CDK4/6 inhibitor therapy. The Phase 2 data set covers 12- and 24-month survival, treatment tolerability, and circulating-tumor-cell biomarker work. The Phase 3 program added Penn Medicine's Abramson Cancer Center as a site on May 13, joining Smilow Cancer Hospital at Yale New Haven and the Los Angeles Cancer Network. The six-abstract BriaCell package at ASCO 2026 — three poster presentations and three publication-only abstracts — establishes the company as the largest peptide-immunotherapy presence at this year's meeting.
