5-Fluorouracil, Oxaliplatin And Dasatinib (Folfox-D) For Previously Untreated Metastatic Pancreatic Adenocarcinoma.

TPS517Background: Systemic chemotherapy for pancreatic adenocarcinoma improves survival and cancer related symptoms. Most targeted agents combined with gemcitabine have consistently failed to demonstrate clinical benefits. Src is overexpressed in pancreatic cancer and promotes an aggressive cancer phenotype. Dasatinib (D) is an oral multi-tyrosine kinase inhibitor (TKI) affecting tumor proliferation through inhibition of Src, Bcr-Abl, CKit and other pathways. Inhibition of Src is associated with biologic modifications favorably modifying the pancreatic cancer phenotype and has synergy with restoring inherent chemosensitivity. Src inhibition can also increase oxaliplatin activity and modulate Tcell responses. The addition of D to the well-established backbone of FOLFOX represents a multifaceted line of scientific investigation. Methods: This is a multicenter phase II trial to determine activity and toxicity of FOLFOX + D in previously untreated metastatic pancreatic adenocarcinoma. Eligible pts must have a...
