NCIt definition : An agonistic recombinant humanized immunoglobulin G1 (IgG1) monoclonal antibody that
recognizes the co-stimulatory receptor OX40 (CD134; tumor necrosis factor receptor
superfamily member 4; TNFRSF4), with potential immunostimulatory activity. Upon administration,
cenzestotug selectively targets, binds to and activates OX40. This may induce the
proliferation of memory and effector T-lymphocytes and inhibit 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.;
