6. At least 18 years of age.
7. Women of child-bearing potential (defined as a sexually mature woman who (1) has not undergone hysterectomy \[the surgical removal of the uterus\] or bilateral oophorectomy \[the surgical removal of both ovaries\] or (2) has not been naturally postmenopausal for at least 24 consecutive months \[i.e., has had menses at any time during the preceding 24 consecutive months\]) must: Either commit to true abstinence from heterosexual contact (which must be reviewed on a monthly basis), or agree to use, and be able to comply with, effective contraception without interruption for 28 days prior to starting study medications (including dose interruptions) and for 3 months after last dose of study medication and Have a negative pregnancy test result at screening and agree to ongoing pregnancy testing at the Investigator's discretion during the course of the study.

2. Any contraindication to curative surgery.

Subjects with tumor fever may be enrolled at the discretion of the Investigator.
7. Known hypersensitivity to any of the components of nal-IRI, other liposomal products, fluoropyrimidines or leucovorin.
8. Neuropathy \> grade 1.
9. Investigational therapy administered within 4 weeks, or within a time interval less than at least 5 half-lives of the investigational agent, whichever is longer, prior to the first scheduled day of dosing in this study.
