NCIt definition : An agonistic humanized 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, revdofilimab selectively
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). 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.;
