BriaCell Treatment Shows Significant Efficacy in Cancer Patients
- Significant Clinical Efficacy: The Bria-IMT treatment achieved complete resolution of right temporal lobe metastasis in a 66-year-old female patient, who survived 27 months post-enrollment, demonstrating the therapy's potential in heavily pre-treated patients.
- Evidence of Immune Activation: CD8 ImmunoPET imaging revealed a significant increase in CD8+ T cells in the cervical lymph nodes post-Bria-IMT treatment, indicating immune system activation that may contribute to long-term survival.
- Study Scale and Results: Among 54 heavily pre-treated metastatic breast cancer patients, 37 received the Bria-IMT regimen, with no reported treatment discontinuations related to Bria-IMT to date, indicating good safety and tolerability of the therapy.
- Future Research Prospects: The ongoing Phase 3 clinical trial (NCT06072612) by BriaCell will further validate the efficacy of Bria-IMT, potentially bringing new hope to cancer treatment.
