Omburtamab is a humanized monoclonal antibody targeting B7-H3 (CD276). Omburtamab selectively binds to B7-H3 highly expressed on the surface of tumor cells and activates anti-tumor immune responses mediated by T cells and natural killer (NK) cells. Omburtamab can promote the specific infiltration of CAR-T cells into tumors, enhance the killing function of NK cells through the CD16 signaling pathway, and regulate tumor cell glucose metabolism (such as inhibiting the Warburg effect). Omburtamab has the potential to inhibit solid tumors such as non-small cell lung cancer (NSCLC).
