Outcome Measures
Primary Outcomes (1)
2 Year Overall Survival
Overall survival is defined as the time from IORT to death due to any cause, or is censored at the date of last follow-up, when applicable.
2 years
Secondary Outcomes (3)
Median Progression Free Survival
2 years
Local Control
2 years
Adverse events associated with IORT
2 years
Study Arms (1)
IORT
EXPERIMENTAL* IORT will be administered as determined to be best practice by the treating radiation oncologist, * Electron beam intraoperative radiation therapy will occur in a hybrid operating room with a portable linear accelerator
Interventions
IORT works by delivering radiation therapy to the tumor while reducing the amount of healthy tissue exposed to the radiation therapy
Eligibility Criteria
You may qualify if:
- Age ≥ 18 years
- ECOG Performance Status 0-1
- Previous completion of at least three (3) months of EITHER gemcitabine plus nab-paclitaxel OR FOLFIRINOX (5-fluorouracil, oxaliplatin, irinotecan and leucovorin)
- Previous completion of either stereotactic-body radiation therapy (SBRT) (minimum 24 Gy) or external beam irradiation (EBRT) (minimum 45 Gy)
- Participation in any investigational drug study within 4 weeks preceding the start of study treatment is PERMITTED.
- Women of childbearing potential (WOCBP) must use appropriate method(s) of contraception. WOCBP should use an adequate method to avoid pregnancy for 5 months after IORT.
- Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year. Men receiving nivolumab and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 7 months after IORT. Women who are not of childbearing potential, i.e., who are postmenopausal or surgically sterile as well as azoospermic men do not require contraception.
- Ability to understand and the willingness to sign a written informed consent document
You may not qualify if:
- Evidence of disease progression or distant metastases.
- Pregnant or lactating women
- Treatment for other invasive carcinomas within the last five years who are at greater than 5% risk of recurrence at time of eligibility screening. Carcinoma in-situ and basal cell carcinoma/ squamous cell carcinoma of the skin are allowed.
- Major surgery, excluding laparoscopy, within 4 weeks of the start of study treatment, without complete recovery
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
- An active infection requiring systemic therapy
- Other serious medical conditions that the investigator feels might compromise study participation
