About this study
Official title: Phase II Study of NALIRIFOX (Nanoliposomal Irinotecan + Oxaliplatin With Fluorouracil and Folinic Acid) in Advanced Unresectable Small Bowel Tumors
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.
- Conditions
- Small Bowel Adenocarcinoma
- Being tested
- Nanoliposomal irinotecan, Oxaliplatin, 5 fluorouracil, Leucovorin
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Nanoliposomal irinotecanDrug
Also called Onivyde
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).
OxaliplatinDrug
Also called Eloxatin
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.
5 fluorouracilDrug
Also called Tolak, Efudex, Fluoroplex
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).
LeucovorinDrug
Also called Wellcovorin, folinic acid
Leucovorin 400 mg/m2 will be administered over 30 minutes IV.

Receives: Drug: Nanoliposomal irinotecan; Drug: Oxaliplatin; Drug: 5 fluorouracil; Drug: Leucovorin |
What is being measured
The primary outcome is the main question the study is designed to answer.
Objective Response Rate (ORR)
ORR is defined as the proportion of subjects with a confirmed complete or partial response to treatment according to RECIST 1.1, by local assessment.
Measured: 3 years
Secondary outcomes (4)
Overall Survival (OS)
OS is defined as the time from initiation of study regimen to date of death due to any cause.
Measured: 3 years
Time to Progression (TTP)
TTP is defined as the time from initiation of study regimen to date of disease progression by RECIST 1.1.
Measured: 3 years
Duration of Response (DOR)
DOR is defined as the time from first documentation of objective response (CR or PR that is subsequently confirmed) to the first documentation of PD (per RECIST 1.1) or ro death due to any cause, whichever comes first.
Measured: 3 years
Number of Participants with Adverse Events
Adverse events will be assessed according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.
Measured: 3 years
