upinitatug
A proprietary humanized monoclonal antibody against human sodium-dependent phosphate transport protein 2B (SLC34A2; NaPi2b), with potential antineoplastic activity. Upon administration of upinitatug, the antibody targets and binds to NaPi2b expressed on tumor cells. Although the tumor cell killing effects of upinitatug are not established, this binding may induce an antibody-dependent cellular cytotoxicity (ADCC)-mediated immune response against NaPi2b-expressing tumor cells, and/or may inhibit NaPi2b-mediated sodium and phosphate ion cotransport activity and ion-dependent tumor cell signaling. NaPi2b, a tumor-associated antigen (TAA), is overexpressed on a variety of tumor cells. It plays a key role in the transport of inorganic phosphate (Pi) and the maintenance of phosphate homeostasis.
