NCIt definition : A humanized monoclonal antibody against the extracellular domain of the human receptor
tyrosine kinase-like orphan receptor 1 (ROR1), with potential antineoplastic activity.
Upon administration, zilovertamab binds to ROR1 and blocks ROR1-mediated signaling.
This prevents tumor cell proliferation in cancer cells overexpressing ROR1. ROR1,
also known as neurotrophic tyrosine kinase, receptor-related 1 (NTRKR1), is normally
expressed during embryogenesis. It is overexpressed in certain leukemias and solid
tumors, but minimally expressed in healthy cells.;
