NEWARK, Del., March 22, 2023 /PRNewswire/ -- Biosion USA, Inc. (Biosion), a global R&D biotechnology company, today announced the upcoming presentations of non-clinical data from its oncology pipeline, including BSI-507: anti-PD1ⅹanti-PVRIG bispecific antibody and BSI-508: anti-PD1ⅹanti-CD47 bispecific antibody, at the American Association for Cancer Research (AACR) Annual Meeting to be held from April 14 to 19, 2023.

BSI-507, a First-in-Class Bispecific Antibody Targeting PD1 and PVRIG for Cancer Immunotherapy

BSI-507, a first-in-class anti-PD1ⅹanti-PVRIG bispecific antibody, discovered through Biosion's H³ antibody discovery platform, is able to block both PD-1 and PVRIG pathways to enhance reversal of T cell inhibition. BSI-507 demonstrates favorable biophysical and functional characteristics, supporting the initiation of development activities including manufacturing and IND-enabling studies.
