anti-TWEAK monoclonal antibody RO5458640

A humanized monoclonal antibody directed against the apoptotic ligand TNF-like weak inducer of apoptosis (TWEAK) with potential antineoplastic activity. Anti-TWEAK monoclonal antibody RO5458640 binds to TWEAK and prevents the binding of TWEAK to its receptor, FGF-inducible molecule 14 (Fn14), thereby blocking the TWEAK/Fn14 signaling. This may prevent tumor cell proliferation, invasion, migration and angiogenesis. TWEAK has pleiotropic effects, mediating proinflammatory and pro-angiogenic activity as well as stimulation of invasion, migration, and survival mediated via its receptor Fn14; Fn14 is expressed at relatively low levels in normal tissues, but is elevated in tumor cells and locally in injured and diseased tissues. Check for active clinical trials using this agent. (NCI Thesaurus)
