NCIt definition : An agonistic recombinant monoclonal antibody that recognizes the co-stimulatory receptor
OX40 (CD134; tumor necrosis factor receptor superfamily member 4; TNFRSF4), with potential
immunostimulatory activity. Upon administration, anti-OX40 agonist monoclonal antibody
BAT6026 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.;
