Biosion, Inc. (“Biosion”), a global R&D stage biotechnology company, announced today the upcoming presentations of non-clinical data from its oncology pipeline, including BSI-060T:  anti-siglec-15 antibody and BSI-082: anti-SIRP antibody, at the American Association for Cancer Research (AACR) Annual Meeting to be held from April 8 to 13, 2022.

BSI-060T,a High Affinity, Fully Human Anti-Siglec-15 Antibody as an Alternative Immune Checkpoint Blocker

BSI-060T is a fully human IgG1κ monoclonal antibody, discovered through Biosion’s H³ antibody discovery platform, is able to bind to Siglec-15 protein with high affinity and to potently neutralize Siglec-15-medicated inhibition of CD3-induced T-cell proliferation. BSI-060T exhibits best-in-class biophysical properties and functional characteristics, supporting the initiation of development activities for multiple indications including non-small lung cancer and breast cancer.
