Phase II Randomized Trial of mFOLFIRINOX +/- Ramucirumab in Advanced Pancreatic Cancer

• Median Overall Survival (mOS) [ Time Frame: From time of registration to the time of documented progression or subject death, assessed up to 33 months ]
  mOS assessed using Kaplan-Meier Survival Analysis to compare outcomes of subjects on experimental arm vs control arm.
• Response Rate (RR) [ Time Frame: From time of registration to the time of documented progression or subject death, assessed up to 33 months ]
  RR assessed using RECIST v1.1
• Characterize Adverse Events (AE) [ Time Frame: From date of first dose until 30 days after the last treatment, assessed up to 33 months ]
  Toxicity assessed using Common Terminology Criteria for Adverse Events v4.0 (CTCAE v4.0)

OUTLINE: This is a multi-center study.

EXPERIMENTAL ARM A:

• Oxaliplatin 85 mg/m^2 over 2-4 hours
• Irinotecan 165 mg/m^2 over 90 minutes
• 5-FU 2,400 mg/m^2 as a 46-hour continuous infusion without the 5-FU bolus to decrease the risk of neutropenia.
• Arm A will receive ramucirumab (RAM) administered as an intravenous infusion over 60 minutes (infusion rate should not exceed 25 mg/min), at a fixed dose of 8 mg/kg every 2 weeks.

CONTROL ARM B :

• Oxaliplatin 85 mg/m2 over 2-4 hours
• Irinotecan 165 mg/m2 over 90 minutes
• 5-FU 2,400 mg/m2 as a 46-hour continuous infusion without the 5-FU bolus to decrease the risk of neutropenia.
• Arm B will receive a placebo infusion every 2 weeks. Due to the double-blinded nature of this study, the volume of placebo will be calculated as if it were RAM.
