BriaCell Therapeutics Corp announced updated Phase 2 survival data for its lead immunotherapy candidate, Bria-IMT, in combination with an immune check point inhibitor (CPI).
AI Summary
BriaCell Therapeutics Corp. recently announced promising updated Phase 2 survival data for its lead immunotherapy candidate, Bria-IMT, when used in combination with an immune checkpoint inhibitor. The study showed that in patients with triple-negative breast cancer, the median overall survival reached 13.9 months, outperforming the 11.8 months reported with the approved antibody-drug conjugate Trodelvy and significantly exceeding the 6.9 months achieved with single-agent chemotherapy.
In addition, for hormone receptor–positive metastatic breast cancer patients, the median overall survival was 17.3 months compared to 14.4 months with Trodelvy and 11.2 months with other chemotherapy treatments. Importantly, the regimen was well tolerated, with no treatment-related discontinuations reported. These encouraging findings come from a study involving heavily pretreated patients and support further evaluation in BriaCell’s ongoing pivotal Phase 3 trial focused on overall survival.

Announcement
BriaCell Therapeutics Corp announced updated results from its ongoing Phase 2 study of Bria-IMT™ in combination with check point inhibitor in patients with advanced metastatic breast cancer (MBC).
AI Summary
BriaCell Therapeutics Corp announced updated, encouraging results from its ongoing Phase 2 study of Bria-IMT™ in combination with a checkpoint inhibitor for advanced metastatic breast cancer patients. In this study, a patient who had failed eight previous treatment regimens, including antibody-drug conjugate therapy, experienced a complete resolution of a temporal lobe brain metastasis. The patient’s orbital tumor has also continued to shrink and shows sustained improvement over more than 18 months of treatment.
Serial imaging at 8, 11, and 20 months confirmed no detectable brain tumor recurrence, while tumor marker levels remained significantly reduced. These findings indicate that the Bria-IMT regimen may offer long-lasting immunotherapeutic benefits for late-stage breast cancer patients with brain metastases who have exhausted other options, underscoring the potential of this novel approach to improve patient outcomes.

Announcement
BriaCell Therapeutics Corp is presenting clinical data from the pivotal Phase 3 study of its lead product candidate, Bria-IMT™, in metastatic breast cancer (BRIA-ABC; NCT06072612) supporting the use of specific biomarkers to predict patients' clinical response to Bria-IMT treatments.
AI Summary
BriaCell Therapeutics Corp. announced new clinical data from its pivotal Phase 3 study evaluating Bria-IMT™ for metastatic breast cancer (BRIA-ABC; NCT06072612). The data highlights the potential use of specific biomarkers to predict patient response to the Bria-IMT treatment. Researchers found that a positive delayed-type hypersensitivity (DTH) reaction and a favorable neutrophil-to-lymphocyte ratio (NLR) were linked to longer progression-free survival. In contrast, the presence of circulating tumor cells (CTCs) after treatment was associated with poorer outcomes, marking it as a negative prognostic indicator.
This promising biomarker research indicates that doctors may soon be able to identify patients who will benefit the most from Bria-IMT, potentially resulting in improved treatment responses and survival rates. The study’s findings support the continued evaluation of these biomarkers in the search for more personalized cancer therapies.

Announcement
BriaCell Therapeutics Corp announces new positive survival data in its Phase 2 study of Bria-IMT plus check point inhibitors (CPI), outperforming ADC drugs in hormone receptor positive (HR+) metastatic breast cancer (MBC) patients.
AI Summary
BriaCell Therapeutics Corp. has shared positive results from its Phase 2 study in metastatic breast cancer. In the study, 25 hormone receptor positive (HR+) patients treated with the Bria-IMT regimen plus checkpoint inhibitors achieved a median overall survival of 17.3 months.
