NCIt definition : An orally bioavailable monoclonal antibody against CXC Chemokine Receptor 4 (CXCR4)
with potential antineoplastic activity. Ulocuplumab binds to the chemokine receptor
CXCR4, preventing the binding of stromal derived factor-1 (SDF-1) to the CXCR4 receptor
and subsequent receptor activation, which may result in decreased tumor cell proliferation
and migration. CXCR4, a chemokine receptor belonging to the G protein-coupled receptor
family, plays an important role in chemotaxis and angiogenesis and is upregulated
in several tumor cell types.;
