NCIt definition : An agonistic, recombinant, humanized, hexavalent immunoglobulin G (IgG) antibody targeting
the co-stimulatory receptor OX40 (CD134; tumor necrosis factor receptor superfamily
member 4; TNFRSF4), with potential immunostimulatory and antineoplastic activities.
Upon administration, anti-OX40 hexavalent agonist antibody INBRX-106 selectively binds
to six OX40 receptors per molecule, thereby clustering and activating OX40. This induces
the proliferation of memory and effector T-lymphocytes and results in a T-cell-mediated
immune response against tumor cells, which leads to tumor cell lysis. OX40, a cell
surface glycoprotein and member of the tumor necrosis factor receptor superfamily
(TNFRSF), is expressed on T-lymphocytes and provides a co-stimulatory signal that
promotes both the proliferation and survival of activated T-cells. Utilizing a hexavalent
OX40 antibody may improve receptor clustering and downstream signaling over tetravalent
or bivalent OX40 antibodies.;
