Programmable half-life and anti-tumour effects of bispecific T-cell engager-albumin fusions with tuned FcRn affinity
Mandrup et al. describe a panel of recombinant albumin fusions, engineered with different affinities to the human neonatal Fc receptor to program the half-life extension of a bispecific (EGFR/CD3) T-cell engager. They show that this approach generates target engagement, T-cell activation, tunable in...

| Summary: | Mandrup et al. describe a panel of recombinant albumin fusions, engineered with different affinities to the human neonatal Fc receptor to program the half-life extension of a bispecific (EGFR/CD3) T-cell engager. They show that this approach generates target engagement, T-cell activation, tunable in vivo half-life extension, cellular cytotoxicity dependent on the cell surface levels of EGFR and can inhibit growth of BRAF mutated EGFR-positive tumours in mice. |
