Eligibility Criteria:
Inclusion Criteria:~1. Provision of written informed consent.~2. Histological or cytological confirmation of colorectal adenocarcinoma (excluding appendiceal and anal canal cancers, as well as signet-ring cell carcinoma) that is unresectable and metastatic.~3. Measurable disease (as defined by RECIST v1.1).~4. Received ≥2 months of a first-line fluoropyrimidine and oxaliplatin-containing regimen for metastatic disease or relapsed within 6 months of completing a fluoropyrimidine and oxaliplatin-containing neoadjuvant/adjuvant therapy. Previous treatment with standard of care chemotherapy regimens in combination with molecular targeted therapies (e.g., VEGF and EGFR pathway inhibitors and immuno-oncology agents) is permitted. Previous treatment with maintenance therapy (e.g., capecitabine) is also allowed. Patients who started on a fluoropyrimidine and oxaliplatin-containing regimen in any setting but must discontinue the oxaliplatin due to.toxicity or allergy (and are now unable to receive oxaliplatin) are considered eligible regardless of the number of cycles of oxaliplatin they received.~5. Known RAS and BRAF status. Patients with wild-type RAS tumours must have received prior treatment with an EGFR inhibitor, unless this was not standard of care according to relevant region-specific treatment recommendations.~6. Known UGT1A1 status, or patient consents to UGT1A1 status testing if unknown.~7. Known DPD activity status, or patient consents to DPD status testing if unknown. See exclusion criterion 1.~8. Age ≥18 years.~9. Minimum life expectancy of ≥12 weeks.~10. Eastern Cooperative Oncology Group (ECOG) Performance status 0 or 1.~11. Adequate bone marrow function as defined by: absolute neutrophil count (ANC) ≥1.5 × 109/L, platelet count ≥100 × 109/L, and haemoglobin ≥9 g/dL. Patients with benign neutropenia may be discussed on a case-by-case basis with the medical monitor.~12. Adequate liver function, as defined by: serum total bilirubin ≤1.5 × ULN), AST and ALT ≤2.5 × ULN (or ≤5 × ULN if liver metastases are present).~13. Adequate renal function assessed as serum creatinine \<1.5 × ULN and glomerular filtration rate ≥50 mL/min (calculated by the Cockcroft-Gault method).~14. Serum albumin ≥3 g/dL.~15. Ability to comply with protocol requirements.~16. Female patients of child-bearing potential must have a negative serum pregnancy test within 7 days prior to the first study drug administration. This criterion does not apply to patients who have had a previous hysterectomy or bilateral oophorectomy. Male patients and female patients of child-bearing potential must agree to practice true abstinence (defined in Section 10.3.1) or to use two forms of contraception, one of which must be highly effective. These forms of contraception must be used from the time of signing consent, throughout the treatment period, and for 6 months following the last dose of any study medication. Oral or injectable contraceptive agents cannot be the sole method of contraception~17. Patients must have been advised to take measures to avoid or minimize exposure of the skin and eyes to UV light, including avoiding sunbathing and solarium use, for the duration of study participation and for a period of 4 weeks following the last dose of study medication~Exclusion Criteria:~1. History of hypersensitivity or current contra-indications to 5-FU, FUDR, or capecitabine.~2. History of hypersensitivity or current contra-indication to any of the combination agents required for the study.~3. History of allergic reactions attributed to components of the NUC-3373 drug product formulation.~4. History of hypersensitivity to Chinese Hamster Ovary (CHO) cell products or other recombinant human or humanised antibodies.~5. History of or known central nervous system or leptomeningeal metastases.~6. Symptomatic ascites, ascites currently requiring drainage procedures or ascites requiring drainage over the prior 3 months.~7. Mutant BRAF V600E status.~8. MSI high or dMMR.~9. Prior treatment with irinotecan.~10. Chemotherapy, hormonal therapy, radiotherapy (other than a short cycle of palliative radiotherapy \[e.g., for bone pain\]\*), immunotherapy, biological agents, or exposure to another investigational agent within 21 days (or four times the half-life for molecular targeted agents, whichever is shorter) of first administration of study treatment:~11. Residual toxicities from prior chemotherapy or radiotherapy which have not regressed to Grade ≤1 severity (CTCAE v5.0), except for alopecia and residual Grade 2 neuropathy.~12. History of other malignancies, except adequately treated non-melanoma skin cancer, curatively treated in situ cancer of the cervix, surgically excised or potentially curatively treated ductal carcinoma in situ of the breast, or low-grade prostate cancer or patients after prostatectomy. Patients with previous invasive cancers are eligible if treatment was completed \>3 years prior to initiating the current study treatment, and the patient has had no evidence or recurrence since then.~13. Presence of an active bacterial or viral infection (including SARS-CoV-2, Herpes Zoster, Varicella Zoster or chickenpox), known Human Immunodeficiency Virus (HIV) positive or known active hepatitis B or C.~14. Presence of any uncontrolled concurrent serious illness, medical condition or other medical history, including laboratory results, which, in the Investigator's opinion, would be likely to interfere with the patient's ability to participate in the study or with the interpretation of the results (refer to protocol for further details).~15. Any condition that, in the judgment of the Investigator, may affect the patient's ability to provide informed consent and undergo study procedures.~16. Patients with a history of haemoptysis (1/2 teaspoon or more of red blood) within 6 months prior to enrolment.~17. Wound healing complications or surgery within 28 days of starting bevacizumab (wound healing must have been fully completed before starting bevacizumab). Investigators may allow patients to initiate treatment with the other study drugs (i.e., NUC-3373/5-FU, LV and irinotecan) on C1D1 but withhold bevacizumab for at least 15 days, but no longer than 28 days, to allow completion of wound healing in patients who would otherwise be eligible for the study, in line with standard local practice and after discussion with the Medical Monitor. Patients who have not received bevacizumab by C2D1 must be replaced.~18. Unhealed wound, active gastric or duodenal ulcer, or bone fracture.~19. Serious thromboembolic event in the 6 months before inclusion.~20. Patients with a history of haemorrhage within 6 months prior to enrolment.~21. Known inherited or acquired bleeding disorders.~22. Red blood cell (RBC) transfusion dependence, defined as requiring more than 2 units of packed RBC transfusions during the 4-week period prior to screening.~23. Uncontrolled hypertension.~24. Severe proteinuria or nephrotic syndrome.~25. Acute intestinal obstruction or sub-obstruction, history of inflammatory intestinal disease or extended resection of the small intestine. Presence of a colic prosthesis.~26. History of abdominal fistulas, trachea-oesophageal fistulas, any other Grade 4 gastrointestinal perforations, non-gastrointestinal fistulas, or intra-abdominal abscesses 6 months prior to screening.~27. Currently pregnant, lactating or breastfeeding.~28. Required concomitant use of brivudine, sorivudine and analogues.~29. Required concomitant use of St John's Wort.~30.

The use of strong CYP3A4 inducers within 2 weeks of first receipt of study drug or the use of strong CYP3A4 inhibitors within 1 week of first receipt of study drug is also excluded.
