Brief summary: Unresectable metastatic colorectal cancer (mCRC) remains an incurable disease. After failure of conventional treatments involving fluoropyrimidines, oxaliplatin and irinotecan in combination or not with biotherapies targeting EGFR and VEGF; regorafenib shows a modest improvement in overall survival. Recently, trifluridine/tipiracil has also shown efficacy in phase 3 with an overall survival of around 7 months. Trifluridine/tipiracil has become the standard of care for advanced mCRC in most western countries. However, the objective response rate remains very low and the survival gain remains moderate (+2 months). Therefore, new strategies are needed to ensure that mCRC patients who have received multiple lines of therapy can receive more effective treatments.

Based on previous clinical trials on IL-1 inhibition and our preclinical data, IL-1 inhibition may increase the efficacy of trifluridine/tipiracil. The goal is to test whether the addition of XB2001 to trifluridine/tipiracil could be synergistic.

Detailed description: This project proposes to evaluate trifluridine/tipiracil plus XB2001 in patients with metastatic colorectal cancer previously treated with oxaliplatin, fluoropyrimidine and irinotecan in combination or not with an anti-angiogenic and an anti-EGFR for RAS Wild type tumor.

The project will consist of a randomized (1:1 ratio), double-blind, non-comparative, multi-center Phase II study with two treatment arms:

* Experimental arm: trifluridine/tipiracil + XB2001
* Control arm: trifluridine/tipiracil + placebo

Eligibility criteria: Inclusion Criteria:

* Male or female that must have signed a written informed consent prior to any study specific procedures
* Aged ≥ 18 years at randomization
* Patient with histologically proven metastatic colorectal cancer previously treated for metastatic disease by chemotherapy treatment including oxaliplatin, irinotecan, fluoropyrimidine, antiangiogenic (anti-VEGF: bevacizumab or aflibercept) and anti-EGFR (cetuximab or panitumumab) if indicated (MSI tumor could be included if previously pretreated with anti PD1/PDL1 therapy) n.b:
* a patient treated with oxaliplatin in a neoadjuvant/adjuvant situation with a recurrence of the disease within 6 months following the last administration is considered resistant to oxaliplatin and validates the criterion if no administration of oxaliplatin has been carried out in a metastatic disease situation.
* exception for VEGF if medically contraindicated during previous metastatic disease treatment (should be clearly documented in the disease history of the patient) it is allowed to included the patient with or without Bevacizumab.
* Have a performance status of 0 or 1 according to the WHO Easter Cooperative Oncology Group (ECOG)
* Knowledge of RAS, BRAF, Microsatellite status
* Baseline tumoral evaluation (thoraco-abdomino-pelvic computed tomography) perfromed within 21 days before randomization with at least one measurable lesion according to RECIST 1.1 criteria.
* Patient willing and able to comply with protocol for the duration of the study including: scheduled visits and exams, visits during the follow-up and treatment compliance.
* Adequat hepatic, renal and bone marrow function within the following limits:
* Total bilirubin ≤ 1,5 times the upper limit of normal (ULN) (unless documented Gilbert's syndrome);

Exclusion Criteria:

* Other concurrent malignancies the last 3 years, except adequately treated cone-biopsied in situ carcinoma (as per exemple of the cervix, basal cell, squamous cell carcinoma of the skin, low risk prostate cancer or other insitu carcinoma juged eligible according the coordinator).
