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.
BSI-508, a Novel Bispecific Fusion Molecule Targeting PD1 and CD47 for Cancer Immunotherapy
BSI-508 is a novel anti-PD1ⅹanti-CD47 bispecific fusion molecule combining both T-cell activation and macrophage mediated phagocytosis together for superior tumor killing. BSI-508 was discovered through Biosion's H³ antibody discovery platform. BSI-508 demonstrates favorable biophysical and functional characteristics, supporting the initiation of development activities including manufacturing and IND-enabling studies.
Biosion is a global, clinical-stage biotechnology company committed to developing antibody-based therapies to improve patient outcomes for the treatment of immune and oncologic diseases. Established in 2017, Biosion has built a pipeline of innovative biologics through its internally derived proprietary technologies including the H³ antibody discovery platform, SynTracer® high-throughput endocytosis platform, and Flexibody™ bispecific platform. Biosion's lead asset, BSI-045B (anti-TSLP mAb), is currently in phase-II for severe asthma and phase-I for atopic dermatitis. Biosion and partners have plans to progress the immune-oncology and antibody drug conjugate-based portfolio into clinical trials for oncology indications over the next year. Biosion has operations in the US, Australia, and China. To learn more about Biosion, please go to www.biosion.com
