abstract = {T cell-based immunotherapy has significantly improved
treatment options for many malignancies. However, despite
these and other therapeutic improvements over the last
decades, gastrointestinal cancers, in particular pancreatic,
hepatic and gastric cancer, are still characterized by high
relapse rates and dismal prognosis, with an accordingly high
unmet medical need for novel treatment strategies. We here
report on the preclinical characterization of a novel
bispecific antibody in an IgG-based format termed CC-3 with
B7-H3xCD3 specificity. In many cancer entities including
pancreatic, hepatic and gastric cancers, B7-H3 (CD276) is
overexpressed on tumor cells and also on the tumor
vasculature, the latter allowing for improved access of
immune effector cells into the tumor site upon therapeutic
targeting. We demonstrate that CC-3 induces profound T cell
reactivity against various pancreatic, hepatic and gastric
cancer cell lines as revealed by analysis of activation,
degranulation and secretion of IL2, IFNγ as well as
perforin, resulting in potent target cell lysis. Moreover,
CC-3 induced efficient T cell proliferation and formation of
T cell memory subsets. Together, our results emphasize the
potential of CC-3, which is presently being GMP-produced to
enable clinical evaluation for treatment of pancreatic,
hepatic and gastric cancer.},
