Basal-like PDAC Treated With Gemcitabine, Erlotinib, and Nab-paclitaxel

Summary

This study explores the best dose of the combination treatment for subjects with advanced unresectable or metastatic basal-like subtype pancreatic adenocarcinoma. For that reason, the safety, efficacy, and tolerability, as well as preliminary estimates of anti-tumor effects of low-dose epidermal growth factor receptor EGFR inhibitors in combination with bi-weekly gemcitabine/nab-paclitaxel (GnP) will be examined in subjects with advanced basal-like pancreatic adenocarcinoma. The Purity Independent Subtyping of Tumors (PurIST) will determine the type of cancer either "basal type" or "classical". If cancer subtype-based first-line chemotherapy in combination with erlotinib will be safe and tolerable in subjects with advanced unresectable or metastatic pancreatic adenocarcinoma of the basal-like subtype as defined by PurIST, as well as provide a preliminary assessment of treatment response in basal-like subjects. This study will also follow a subset of subjects with classical subtypes that are treated per standard of care on oxaliplatin-based triplet chemotherapy.
