FOLFIRINOX in Metastatic High Grade Gastroenteropancreatic Neuroendocrine Carcinomas
Gastro-enteropancreatic Neuroendocrine Tumor, Pancreatic Cancer, Neuroendocrine Carcinomas of Pancreas

About this trial
This is an interventional treatment trial for Gastro-enteropancreatic Neuroendocrine Tumor focused on measuring Gastroenteropancreatic neuroendocrine carcinomas (GEP-NECs), Metastatic, High grade, Pancreas, Neuroendocrine carcinoma of gastrointestinal tract
Eligibility Criteria
Inclusion Criteria:
- Histologically or cytologically confirmed neuroendocrine carcinoma of the gastrointestinal (GI) tract. Potential participants with unknown origin for the neuroendocrine carcinoma in which a gastroenteropancreatic origin is suspected (per pathologist or investigator discretion) will be eligible for the study.
 - Tumors must have a Ki-67 index greater than 20% and/or >20 mitotic figures/10 high-power fields.
 - Must have metastatic disease.
 - Must measurable disease, as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.
 - Any line of treatment (first line versus beyond first line).
 - Age >18 years.
 - Life expectancy of greater than 12 weeks.
 - Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2.
 - Must have adequate organ and marrow function.
 - Ability to understand and the willingness to sign a written informed consent document.
 
Exclusion Criteria:
- Have had chemotherapy or radiotherapy within 3 weeks prior to entering the study.
 - Receiving any other investigational agents.
 - Untreated brain or meningeal metastases.
 - Prior treatment with 5-fluorouracil (5-FU), irinotecan or oxaliplatin.
 - Pre-treatment peripheral neuropathy greater than grade 1 per the CTCAE, version 4.0.
 - 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.
 - A secondary primary cancer (excluding baso/squamous cell carcinoma of skin) within 1 year.
 - Active viral hepatitis or autoimmune hepatitis. The work-up to confirm active hepatitis or autoimmune hepatitis will only be done if clinical suspicion based on investigator discretion.
 - Potential participants with childbearing potential who are not willing to use adequate contraception precautions during the study and for 3 months after stopping study chemotherapy.

Arms of the Study
Arm 1
Experimental
FOLFIRINOX Treatment
Participants will receive modified FOLFIRINOX which consists of 85 mg/m^2 of oxaliplatin, 400 mg/m^2 of leucovorin over the first 2 hours, 165 mg/m^2 of irinotecan in a 90-minute infusion on day 1, followed by a continuous, 46-hour infusion of 5-FU at a dosage of 2,400 mg/m^2. A cycle will be repeated every 14 days. Granulocyte colony-stimulating factor (G-CSF) prophylaxis will be allowed after each cycle. Participants will undergo re-staging studies every 8 weeks. Participants will receive up to 12 cycles during the study. Additional cycles will be determined per investigators' discretion.
