Detailed description

This is a Phase II trial of NEOADJUVANT FOLFIRINOX CHEMOTHERAPY WITH PEMBROLIZUMAB followed by SURGERY and Adjuvant PEMBROLIZUMAB for Patients with LOCALIZED, RESECTABLE Adenocarcinoma of the pancreas. Investigators hypothesize that appropriately timed neoadjuvant FOLFIRINOX with anti-PD-1 mAb (pembrolizumab) can be administered safely and feasibly, and that this combination will lead to improved clinical response associated with enhanced numbers of immune cells in surgically resected pancreatic tumors. Patients will receive 6 cycles of FOLFIRINOX with 2 cycles of PEMBROLIZUMAB before surgical resection. Following surgery patients will receive 5FU based chemotherapy for up to 6 cycles with 7 more cycles of PEMBROLIZUMAB. Patients will receive a total of 9 doses of Q6week cycles of PEMBROLIZUMAB. Toxicities will be continuously monitored using the method proposed by Ivanova et al. \[Ivanova, A., Qaqish, B.F., and Schell, M.J. (2005). Continuous toxicity monitoring in phase II trials in oncology. Biometrics 61: 540-545.\]. The method generates a Pocock-type stopping boundary for repeated testing for toxicity. Sequential boundaries will be used to monitor dose-limiting toxicity rate. The accrual will be halted if excessive numbers of dose-limiting toxicities are seen, that is, if the number of dose-limiting toxicities is equal to or exceeds boundary number out of the number of patients with full follow-up. This is a Pocock-type stopping boundary that yields the probability of crossing the boundary at most 5% when the rate of dose-limiting toxicity is equal to the acceptable rate of 25%.

Conditions

• Pancreatic Ductal Adenocarcinoma

Interventions

Type	Name	Description
DRUG	Pembrolizumab	Pembrolizumab will be initiated starting with the Cycle 2 Day 1 and will be administered every 6 weeks with a max amount of 9 cycles throughout the study.
DRUG	Folfirinox	Once eligibility has been confirmed and the patient has been registered to the study, the patient will begin induction modified FOLFIRINOX (Oxaliplatin, Leucovorin, Irinotecan, 5-Fluorouracil) chemotherapy treatment. Each cycle is 14 days; a total of six cycles will be administered. Patients will receive growth factor support at the discretion of treating physician.
