Bria-OTS+: A versatile therapeutic platform for inducing anti-cancer immunity
(AACR 2025)
- "Initial results with the SV-BR-1-GM (Bria-IMT) breast cancer cell line, expressing GM-CSF, have shown promise. Bria-OTS+ is an adaptable cancer immunotherapy platform with strong clinical potential. It expresses a broad range of cancer antigens, including Tumor-Associated Antigens and Post-Translational Modifications, to stimulate robust immune responses. The platform activates both adaptive and innate immunity, overcoming immune escape by engaging NK cells in cases of HLA deletion."

Identification of Antigenic Determinants in SV-BR-1 derived Cellular Breast Cancer Vaccines
(SABCS 2024)
- "This study identified a wide array of antigenic determinants in SV-BR-1 derived cellular breast cancer vaccines using MHC-associated peptide profiling and antigen/epitope mapping. The analysis revealed diverse peptides, including PTM and mutated variants, in MHC class I and II molecules. These findings highlight the potential of vaccines like Bria-IMT and Bria-OTS+ to elicit strong immune responses by presenting a broad range of tumor-specific antigens, paving the way for improved personalized cancer immunotherapy strategies."
