Here we report the design of a prospective, non-randomized multi-centered Phase II clinical study evaluating the effects of the Fluoropyrimidine-carbamate Capecitabine (Xeloda ®) and the monoclonal anti-HER2 antibody Trastuzumab (Herceptin®) in patients with non-resectable, HER2 overexpressing pancreatic cancer. This evidence concerns the gene ERBB2 and pancreatic neoplasm.
