NCIt definition : An agonistic, hexabody-based monoclonal antibody that recognizes the co-stimulatory
receptor OX40 (CD134; tumor necrosis factor receptor superfamily member 4; TNFRSF4),
with potential immunostimulatory and antineoplastic activities. Upon administration,
anti-OX40 agonist monoclonal antibody GEN1055 selectively targets and binds to OX40,
thereby forming a hexamer and inducing OX40 clustering. This activates OX40 and induces
the proliferation of memory and effector T-lymphocytes and inhibits the function of
T-regulatory cells (Tregs) in the tumor microenvironment (TME). This enhances anti-tumor
immune responses and prevents Tregs-mediated immune suppression. OX40, a cell surface
glycoprotein and member of the tumor necrosis factor receptor superfamily (TNFRSF),
is expressed on T-lymphocytes and plays an essential role in T-cell activation and
differentiation.;
