bintrafusp alfa
A bifunctional fusion protein composed of avelumab, an anti-programmed death ligand 1 (PD-L1) human monoclonal antibody, bound to the soluble extracellular domain of human transforming growth factor beta (TGFbeta) receptor type II (TGFbetaRII), with potential antineoplastic and immune checkpoint modulating activities. Upon administration, the TGFbetaRII moiety of bintrafusp alfa binds to and neutralizes TGFbeta while the avelumab moiety simultaneously binds to PD-L1. This prevents TGFbeta- and PD-L1-mediated signaling, and increases natural killer (NK) cell and cytotoxic T-lymphocyte (CTL) activities. This inhibits tumor cell proliferation in susceptible tumor cells. TGFbeta and PD-L1 are both upregulated in certain types of cancers; their overexpression is associated with increased evasion of immune surveillance and contributes to poor prognosis. Check for active clinical trials using this agent. (NCI Thesaurus)
