NCIt definition : An agonistic humanized monoclonal antibody against the receptor, OX40 (CD134), with
potential immunostimulatory and antineoplastic activities. Upon intravenous administration,
vonlerolizumab selectively binds to and activates OX40, by mimicking the action of
endogenous OX40 ligand (OX40L). OX40 activation induces proliferation of effector
T-lymphocytes and inhibits the activity of regulatory T-cells. In the presence of
tumor-associated antigens (TAAs), this may promote an immune response against the
TAA-expressing tumor cells. OX40, a cell surface glycoprotein and member of the tumor
necrosis factor (TNF) receptor superfamily, is expressed on T-lymphocytes and provides
a co-stimulatory signal for the proliferation and survival of activated T-cells.;
