In an replace of a part 2 examine, investigators reported that Bria-IMT mixed with an immune checkpoint inhibitor confirmed improved total survival in closely pretreated sufferers with metastatic breast most cancers, in accordance with a information launch from BriaCell.
“We’re thrilled to see our Bria-IMT routine outperform established benchmarks like Trodelvy in TNBC and HR+ MBC sufferers,” Dr. William V. Williams, BriaCell’s president and CEO, mentioned within the information launch. “BriaCell’s sufferers had failed a median of six prior therapies, underscoring the potential scientific impression of our novel immunotherapy. We stay up for validating these findings in our ongoing pivotal part 3 examine with total survival as its major endpoint.”
For triple-negative breast most cancers, the median total survival was 13.9 months with BriaCell’s remedy, in contrast with 11.8 months for the antibody-drug conjugate Trodelvy (sacituzumab govitecan-hziy) and 6.9 months for single-agent chemotherapy. BriaCell’s prior median survival, reported on the 2025 ASCO Annual Assembly in June 2025, was 11.4 months.
Amongst sufferers with hormone receptor-positive breast most cancers, the median total survival with BriaCell’s remedy was 17.3 months in contrast with 14.4 months for Trodelvy and 11.2 months for single-agent chemotherapy.
In sufferers with triple-negative breast most cancers, remedy with Bria-IMT plus a checkpoint inhibitor utilizing the part 3 formulation resulted in a 78% survival price at six months and 56% at 12 months. For comparability, six- and 12-month survival charges had been 80% and 49% with Trodelvy, and 56% and 22% with single-agent chemotherapy.
Amongst sufferers with hormone receptor-positive breast most cancers, the Bria-IMT mixture confirmed six- and 12-month survival charges of 90% and 61%, respectively. Survival with Trodelvy was 83% at six months and 61% at 12 months, whereas single-agent chemotherapy resulted in 76% and 47% survival on the identical time factors.
The part 2 Bria-IMT examine enrolled 54 sufferers with closely pretreated metastatic breast most cancers, who had acquired a median of 6 prior therapies, to guage the Bria-IMT routine mixed with a checkpoint inhibitor. Amongst them, 37 sufferers had been handled with the identical formulation now being utilized in BriaCell’s ongoing pivotal part 3 trial in metastatic breast most cancers. As of the latest replace, no sufferers have discontinued because of unwanted effects associated to Bria-IMT.
Sustained Full Decision of Temporal Lobe Mind Metastasis
Moreover, a affected person with breast most cancers who’s enrolled on BriaCell’s part 2 examine of Bria-IMT plus checkpoint inhibitor has sustained an entire decision of a mind metastasis and continued tumor shrinkage behind the attention for greater than 18 months, in accordance with an extra information launch from BriaCell.
The metastatic tumor had initially brought about proptosis, or eye bulging. This affected person, who had beforehand acquired a number of remedies for metastatic breast most cancers, confirmed these responses as early as 8 and 11 months into remedy. Now, greater than 18 months later, there may be nonetheless no signal of the mind tumor returning, and the orbital lesion continues to shrink.
“These encouraging outcomes proceed to counsel that our novel Bria-IMT routine might present sturdy immunotherapeutic profit in late-stage breast most cancers sufferers with mind metastases who’ve exhausted different choices,” Williams mentioned within the information launch. “The long-term response noticed on this affected person reinforces the potential of Bria-IMT to enhance outcomes whereas sustaining a good tolerability profile.”
The affected person had failed eight prior remedy regimens, together with an antibody-drug conjugate, earlier than beginning Bria-IMT plus checkpoint inhibition. She has now accomplished 29 remedy cycles and remained on the examine for greater than 21 months. Imaging at 8, 11 and now 20 months confirmed no detectable illness in the proper temporal lobe and continued response within the orbital lesion. Her tumor markers have additionally stayed markedly decrease than baseline, supporting the sustained radiologic response.
