• 1 other identifier: HCRN GI23-617
• Study Type: interventional
• Target: 36
• Locations: 1 country
• Sites: 5

Brief Summary

The study regimen will be administered on an outpatient basis and all medications are administered intravenously (IV). Subjects will receive treatment on Day 1 and Day 15 of each 28-day cycle consisting of the following: nanoliposomal irinotecan at 50 mg/m2, followed by oxaliplatin 60 mg/m2, followed by leucovorin at 400 mg/m2 30 minutes after completion of oxaliplatin, followed by 5-FU 2400 mg/m2 60 minutes after leucovorin completion. Subjects will receive up to 6 cycles of NALIRIFOX then based on response and per physician discretion, de-escalated maintenance treatment with NALIRIFOX minus oxaliplatin may continue. Subjects will continue de-escalated maintenance treatment until progression per RECIST 1.1, intolerable toxicity or physician/subject choice to discontinue.

NALIRIFOX and De-escalated maintenance

EXPERIMENTAL

Cycle 1 to Cycle 6: NALIRIFOX Subjects will receive treatment on Day 1 and Day 15 of each 28-day cycle consisting of the following: nanoliposomal irinotecan at 50 mg/m2, followed by oxaliplatin 60 mg/m2, followed by leucovorin at 400 mg/m2 30 minutes after completion of oxaliplatin, followed by 5-FU 2400 mg/m2 60 minutes after leucovorin completion. Patients will receive up to 6 cycles of NALIRIFOX. Cycle 7+: De-escalated Maintenance: Based on response to Cycles 1-6 and per physician discretion, de-escalated maintenance treatment with NALIRIFOX minus oxaliplatin may continue as de-escalated maintenance treatment until progression per RECIST 1.1, intolerable toxicity or physician/subject choice to discontinue.

Drug: Nanoliposomal irinotecan; Drug: Oxaliplatin; Drug: 5 fluorouracil; Drug: Leucovorin

Interventions

Oxaliplatin DRUG

Oxaliplatin 60 mg/m2 will be administered over 120 minutes (± 10 minutes) IV. Institutional standards may be used for all aspects of oxaliplatin administration including premedication administration.

Also known as: Eloxatin

NALIRIFOX and De-escalated maintenance

5 fluorouracil DRUG

5-FU will be administered as a continuous infusion over 46 hours. Subjects will go home with an infusion pump and return to clinic at the end of infusion for removal of the pump or, if possible, the pump may be removed at the subject's home (except on Cycle 1 Day 3).

Also known as: Tolak, Efudex, Fluoroplex

NALIRIFOX and De-escalated maintenance

Leucovorin DRUG

Leucovorin 400 mg/m2 will be administered over 30 minutes IV.

Also known as: Wellcovorin, folinic acid

NALIRIFOX and De-escalated maintenance

Nanoliposomal irinotecan DRUG

Nanoliposomal Irinotecan 50 mg/m2 will be administered over 90 minutes (± 10 minutes) IV. All subjects must be pre-medicated prior to nanoliposomal irinotecan infusion with standard doses of dexamethasone and a 5-HT3 antagonist, or equivalent other anti-emetics (according to standard institutional practices).

Also known as: Onivyde

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subject has been informed about the nature of the study, and has agreed to participate in the study, and signed the ICF prior to participation in any study-related activities. Also, as determined by the enrolling physician or protocol designee, ability of the subject to understand and comply with study procedures for the entire length of the study.
• Age ≥ 18 years at the time of consent.
• ECOG Performance Status of ≤ 1 within 28 days prior to registration and within 7 days prior to start of study regimen.
• Histological or cytologically confirmed small bowel adenocarcinoma per AJCC, 9th edition that has not been previously treated in the metastatic setting. Subjects treated in the adjuvant setting who completed treated \> 6 months and do not have residual toxicities \> Grade 1 are eligible. NOTE: Subjects with only localized disease or disease which will likely become resectable after chemotherapy (per investigator discretion) are NOT eligible.
• Mismatch repair proficient (MMRp) and/or microsatellite stable (MSS) disease per institutional standard of care testing.
• Subject has one or more metastatic lesions measurable by CT scan (or MRI, if the subject
• a. is allergic to CT contrast media) according to RECIST Version 1.1 criteria. Lesions in a prior radiation field must have progressed subsequent to radiotherapy to be considered measurable.
• Demonstrate adequate organ function as defined below. All screening labs to be obtained within 28 days prior to registration and repeated within 7 days prior of C1D1.
• Platelets (Plt) ≥ 100,000 cells/mm3
• Absolute Neutrophil Count (ANC) ≥ 1,500 cells/mm3; without the use of hemopoietic growth factors
• Hemoglobin (Hgb) ≥ 9 g/dL
• Calculated creatinine clearance ≥ 30 mL/min; Cockcroft-Gault formula for actual body weight should be used for calculation. For subjects with a body mass index (BMI) \> 30 kg/m2, adjusted body weight should be used instead
• Total bilirubin ≤ 1.5 × ULN
• Aspartate aminotransferase (AST) ≤ 2 × ULN; \< 5× with liver metastases
• Alanine aminotransferase (ALT) ≤ 2 × ULN; \< 5× with liver metastases

You may not qualify if:

• Adenocarcinoma originating in the ampulla or appendix (duodenal tumors that involve the ampulla but originate in the duodenum are eligible).
• Neuroendocrine or any other histology different than adenocarcinoma.
• Prior treatment with irinotecan.
• Prior treatment of SBA in the metastatic setting with surgery, radiotherapy, chemotherapy or investigational therapy:
• Palliative radiotherapy is permitted but lesions in a prior radiation field must have progressed subsequent to radiotherapy to be considered measurable.
• Placement of biliary stent/tube is permitted.
• Known history of central nervous system (CNS) metastases. (subjects on a stable or decreasing dose of steroids and deemed clinically stable as per the investigator's assessment are eligible).
• Clinically significant gastrointestinal disorder including hepatic disorders, bleeding, inflammation, occlusion, diarrhea \> Grade 1, malabsorption syndrome, ulcerative colitis, inflammatory bowel disease, or partial bowel obstruction.
• Pregnant or breastfeeding. NOTE: breast milk cannot be stored for future use while the mother is being treated on study.
• History of any second malignancy in the last 2 years; subjects with prior history of in-situ cancer or basal or squamous cell skin cancer are eligible. Subjects with a history of other malignancies are eligible if they have been continuously disease free for at least 2 years prior to screening. Subjects who have a concurrent malignancy that is clinically stable and does not require tumor-directed treatment are eligible.
• Known hypersensitivity to any of the components of nanoliposomal irinotecan, other liposomal products, or any components of 5-FU, LV or oxaliplatin.
• Concurrent illnesses that would be a relative contraindication to trial participation such as active cardiac or liver disease, including:
• Severe arterial thromboembolic events (myocardial infarction, unstable angina pectoris, stroke) less than 6 months before screening
• High cardiovascular risk, including, but not limited to, recent coronary stenting or myocardial infarction in the past year prior to screening
• New York Heart Association (NYHA) Class III or IV congestive heart failure, ventricular arrhythmias or uncontrolled blood pressure
