Study of Pre-surgery Gemcitabine + Hydroxychloroquine (GcHc) in Stage IIb or III Adenocarcinoma of the Pancreas

This is a phase I/II trial designed to assess the safety, tolerability and efficacy of neoadjuvant oral hydroxychloroquine (Plaquenil®) in combination with FDR gemcitabine in subjects with high risk IIb or III adenocarcinoma of the pancreas. Eligible subjects will be administered hydroxychloroquine orally once or twice daily (depending on dose) in combination with FDR gemcitabine (on days 1 and 15) for 31 days prior to surgical resection. Dose escalations of hydroxychloroquine will proceed using Storer's Up-and-Down algorithm D. Subjects will be monitored for side effects and tolerability of the drug. Pre- and post-treatment PET scans will be the primary means to assess response to therapy. Resected tumors will also be assessed for evidence of inhibition of autophagy as well as histopathologic response and margin negative resection and number of positive lymph nodes.
