Comprehensive in vitro characterization revealed that targeting the membrane-proximal epitope Q179 of the B7-H3 molecule allowed for a 100-fold reduction of CD3 affinity in our lead compound CC-3 with preserved superior tumor cell killing, efficient T cell activation, proliferation and memory formation, whereas undesired cytokine release was reduced...The trial will consist of a dose escalation part with an accelerated and a standard titration phase to determine the maximum tolerated dose followed by a dose expansion part to define the recommended phase II dose and collect first signs of efficacy. Together, we report on the straight forward development of a novel optimized bsAb from bench to first clinical evaluation that holds promise to improve treatment of CRC patients.
