Eligibility Criteria:
Inclusion Criteria:
1. Individuals that are carriers of a pathogenic or likely pathogenic germline variant in one of the mismatch repair genes (MLH1, MSH2, MSH6).
2. Participants must have no evidence of active or previous invasive cancer.
3. Participants must have endoscopically accessible colon.
4. Participants must consent to follow the standard of care surveillance with colonoscopy and biopsies every 1-2 years.
5. Age ≥ 18 years
6. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 1 (Karnofsky ≥70%).
7. Haemoglobin ≥10 g/dL or haematocrit ≥30%; Leukocyte count ≥3.0x109/l; Platelet count ≥100x109/l; Absolute neutrophil count ≥1.5x109/l; Absolut lymphocyte count ≥0.8x109/l.
8. Creatinine clearance (calculated if measured is not available) ≥60mL/min/1.73m2.
9. Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\]/alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase \[SGPT\] ≤2 times the institutional upper limit of normal (ULN).
10. Total bilirubin ≤ 1.5 the ULN; participants with Gilbert's disease may be enrolled with higher total bilirubin if their direct bilirubin is ≤1.5 times the ULN.
11. Written informed consent.
12. Women of child-bearing potential\* must have a negative pregnancy test in serum before the inclusion in the study and agree to use highly effective contraceptive methods until one year following the las immunization dose. Highly effective contraceptive methods will include: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable), intrauterine device, bilateral tubal occlusion, vasectomized partner and sexual abstinence. \* A woman will be considered of childbearing potential, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as 0 menses for 12 months without an alternative medical cause. A high follicle stimulating hormone level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. However, in the absence of 12 months of amenorrhea, a single follicle stimulating hormone measurement is insufficient.
Exclusion Criteria:
1. Individuals that are carriers of a pathogenic or likely pathogenic germline variant in PMS2.
2. Individuals with active malignancy or previous malignancy (excluding non-melanoma skin cancer)
3. Participants who cannot be removed from their baseline medication for the duration of the trial to administer the investigational treatment. This includes the daily use of \>100 mg aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) or cyclooxygenase (COX) inhibitors.
4. Any serious uncontrolled and /or unstable pre-existing medical disorder (aside from malignancy exception above), psychiatric disorder, or other conditions that could interfere with participant's safety, obtaining informed consent, or compliance to the study procedures.
5. Patients with active systemic bacterial, viral or fungal infections or known to have human immunodeficiency virus (HIV) or to test positive for HIV antibody at screening.
6. Positive hepatitis B surface antigen or hepatitis C antibody tests at screening.
7. History of organ allograft or other history of immunodeficiency
8. Individuals with a condition requiring systemic treatment with either corticosteroids or other immunosuppressive medications.
9. Pregnant or breastfeeding or planning to become pregnant during the first year after the completion of the study treatment.
10. Men attempting or planning to conceive children during the first year after the completion of the study treatment.
11. Participants cannot receive any other investigational agents in the last month before its inclusion.
12. Participants unable to refrain to receive any type of vaccination during the first 12 weeks of the trial.
13. Impossibility to proceed to the leukapheresis (e.g. absence of peripheral venous access).
14. Any other problem that according to the investigator could interfere with the evaluation of the objectives
