Clinical Trial Summary

Neoadjuvant chemotherapy has gained acceptance in treating locally advanced breast cancer, esophageal cancer, gastric cancer, and rectal cancer. However, the role of neoadjuvant chemotherapy for locally advanced colon cancer is still in the exploratory stage. The objective of this study is to explore the efficacy and safety of nanoliposomal irinotecan and oxaliplatin combined with capecitabine as a novel conversion therapy for locally advanced colorectal cancer patients.

Description:

After patients are enrolled, they will receive a modified FOLFOXIRI regimen (nanoliposomal irinotecan 60mg/m2, oxaliplatin 85 mg/m2, and capecitabine 800 mg/m2 twice daily, day 1 to 7), repeated every two weeks. The efficacy and resectability were evaluated every four cycles. Patients who had lesions that were radically resectable after evaluation will receive surgery. This medication will be administrated until disease progression or unacceptable toxicity or resectability or up to a maximum of 12 cycles.

13. Women with reproductive potential (< 2 years after the last menstrual period) and men use effective contraceptive methods until half a year after the last treatment.

Exclusion Criteria:

1. Patients who had shown hypersensitivity to the test drugs or other liposomal products.

2. Patients who have participated in other clinical trials in the past 4 weeks.

3. Previous or concurrent cancer diagnosed within 5 years (except cured basal cell carcinoma or squamous cell carcinoma of the skin and carcinoma in situ of the cervix; the treatment of other malignant tumors has been completed for more than 5 years, and there is no clinical and imaging evidence of recurrence or progression except).

4. dMMR/MSI-H-type colorectal cancer.

5. Symptomatic peripheral neuropathy = grade 2 (CTCAE 5.0).

6. Patients unable to swallow or lack of physical integrity of the upper gastrointestinal tract, malabsorption syndrome, or inability to take oral medication.

7. Patients had severe bleeding (CTCAE 5.0 grade =3) in the previous 4 weeks.
