Brief Summary:
This trial aims to determine a safe schedule of short-course proton beam radiation therapy with adjuvant mFOLFIRINOX for patients with resected pancreatic adenocarcinoma.

Condition or disease Intervention/treatment Phase
Resected Pancreatic Adenocarcinoma Drug: mFOLFIRINOX Radiation: Proton beam radiation Phase 1

Detailed Description:

The investigators hypothesize that resected pancreatic cancer patients will benefit from enhanced local control with the addition of radiation therapy to adjuvant FFX. The recently reported PRODIGE 24 study, demonstrated that 12 cycles of adjuvant FFX without radiation therapy significantly improved survival and time to metastatic failure rates as compared to GEM alone. Excessive distant failures rates using prior adjuvant systemic therapies, may have limited the impact of radiation therapy; therefore, improvements in systemic control can increase the benefit of local control.

In this study, the investigators utilize 5 fraction PRT, delivered over 1 week, during adjuvant FFX (between cycles 6 and 7) to minimize the interruptions in chemotherapy as well as to reduce the length of time from surgical resection to initiating adjuvant radiation therapy. Conventional radiation therapy is typically delivered over 5 weeks and is commonly given after the completion of adjuvant chemotherapy. Conventional radiation therapy cannot be given concurrently with FFX due to the synergistic toxicities. In contrast, PRT significantly reduces the exposure of normal tissues to the effects of radiation therapy and has been safely delivered using a 5 fraction schedule with chemotherapy, as previously discussed.

Chemotherapy will consist of mFOLFIRINOX in 14-day cycles x 12 as used in the PRODIGE 24 study:

  • Irinotecan 150 mg/m2 IV day 1
  • Oxaliplatin 85 mg/m2 IV day 1
  • Leucovorin 400 mg/m2 IV day 1
  • 5-fluorouracil 2,400 mg/m2 IV days 1-3 (no bolus)
  • Pegfilgrastim 6 mg SC on-body injector day 3 (optional, up to investigator's discretion, can alternatively do day 4 without on-body injector)
  • Suggested supportive care medications: fosaprepitant 150 mg IV day 1, dexamethasone 12 mg IV day 1, ondansetron 16 mg IV day 1, dexamethasone 4 mg PO q AM days 2-3, ondansetron 8 mg PO BID days 2-3.
  • Dose adjustments will be permitted at the discretion of the treating oncologist based on patients' prior tolerability to FFX
  • Proton radiation will consistent of 5 daily doses of 5 GyE total, ideally administered Monday through Friday but can be administered within 7 business days, between cycles 6 and 7

Primary Outcome Measures :
  1. Recommended phase II dose and schedule (RP2D) of short-course PRT integrated within adjuvant mFOLFIRINOX [ Time Frame: 6 months ]
    Using a 3+3 dose-escalation schema, 2-12 patients will be required to determine the RP2D.

  2. Safety (adverse events) of short-course PRT integrated within adjuvant mFOLFIRINOX [ Time Frame: 6 months ]
    adverse event data will be collected and presented as descriptive statistics using the CTCAE version 5.0

  3. Feasibility (rate of successful completion) of short-course PRT integrated within adjuvant mFOLFIRINOX [ Time Frame: 6 months ]
    we will track the success rate in screening patients, completion of proton beam planning, completion of proton beam treatment, and completion of adjuvant therapy (including number of cycles completed and relative dose intensity).


Secondary Outcome Measures :
  1. Recurrence-free survival (RFS) [ Time Frame: 6 months ]
    Defined as time from surgery until evidence of disease recurrence.

  2. Overall survival (OS) [ Time Frame: 6 months ]
    Defined as time from surgery until death from any cause or last follow-up.
