PHILADELPHIA and VANCOUVER, British Columbia, Dec. 13, 2024 (GLOBE NEWSWIRE) -- BriaCell Therapeutics Corp. (Nasdaq: BCTX, BCTXW) (TSX: BCT) ("BriaCell" or the "Company"), a clinical-stage biotechnology company that develops novel immunotherapies to transform cancer care, highlights the infiltration of cancer fighting immune cells into tumors, using leading CD8 ImmunoPET imaging technology, in its poster presentation at the 2024 San Antonio Breast Cancer Symposium ® at Henry B. Gonzalez Convention Center, San Antonio, TX.
Today's poster shows influx of cancer fighting immune cells into tumors and lymphatic tissue leading to cancer cell destruction following treatment with the Bria-IMT™ plus CPI regimen. BriaCell employed this advanced imaging technology as a precision diagnostic tool to monitor patients' immune system responses in its phase 2 study, establishing the ability of the Bria-IMT™ regimen to induce tumor infiltration with CD8+ "killer" T cells. These results suggest a potential value of CD8 ImmunoPET in identifying pseudo progression in patients with clinical benefit vs tumor progression. CD8+ T cell infiltration also correlated with a marked reduction in tumor markers, indicating clinical benefit, in some patients.
"We are excited to successfully utilize innovative technology such as CD8 ImmunoPET imaging to gain insight into the mechanism of action and potential strength of the BriaCell immunotherapy program," stated Russ Kuker, MD, Associate Professor of Clinical Radiology at the University of Miami Miller School of Medicine and author of the P5-10-12 poster.
"By employing more accurate precision imaging techniques, we have been able to document the mechanism of action of the Bria-IMT™ regimen as we progress this therapy to revolutionize the way we treat cancer patients and improve patient outcomes," noted Giuseppe Del Priore, MD, MPH, BriaCell's Chief Medical Officer.
The details about the poster presentation are as follows:
Abstract Number: SESS-1069
Title: Bria-IMT CD8+ tumor infiltrating lymphocytes turn "Cold" tumor "Hot" in metastatic breast cancer
Time: Friday, December 13, 2024 12:00 PM - 2:00 PM CST
Presentation ID: P5-10-12
CD8 ImmunoPET imaging, an imaging analysis technology, is used to mark CD8+ T-cells (also known as cytotoxic "killer" T cells) that are important components of the immune system and key to cancer cell detection and destruction.
Bria-IMT™ plus CPI produced cancer-fighting CD8+ T cells infiltration into metastatic tumors and lymphoid tissue, leading to cancer destruction - turning "Cold" tumors and lymph nodes "Hot" on ImmunoPET imaging
Using metastatic site-specific CD8+ PET imaging technology, BriaCell reports the following in 6 patients treated {median # of prior treatments = 7; prior lines of treatment included antibody-drug conjugates (ADCs) and CPIs} with Bria-IMT™ plus CPI after 9 cycles (27weeks) of treatment:
In summary, advanced ImmunoPET imaging technology correlates with clinical benefit with the Bria-IMT™ combination regimen in metastatic breast cancer and suggests possible use in identifying immunotherapy responsive tumors. These findings support the continued use of the Bria-IMT™ combination regimen in BriaCell's ongoing pivotal Phase 3 study (listed on ClinicalTrials.gov as NCT06072612 ) in MBC.
