Inclusion Criteria: 1. Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. Written informed consent and any locally required authorization (e.g., Health Insurance Portability and Accountability Act in the US, European Union \[EU\] Data Privacy Directive in the EU) obtained from the patient/legal representative prior to performing any protocol-related procedures, including screening evaluations. 2. Age \> 18 years at time of study entry. 3. HLA type: HLA-A\*02 and/or HLA-A\*24 positive. 4. Very early, early and intermediate stage (Barcelona Clinic Liver Cancer (BCLC) stage 0, A, B disease) hepatocellular carcinoma (HCC) diagnosed by biopsy or resected tissue (patho-histological diagnosis) or imaging findings (non-invasive criteria) following any standard treatment (e.g. hepatic resection, Radiofrequency Ablation / Percutaneous Ethanol injection (RFA/PEI), Transarterial chemoembolization (TACE) and SIRT) and without any evidence of active disease that warrant further treatment. 5. Minimum life expectancy of 1 year. 6. Patho-histological diagnosis of HCC based on biopsy is required for all nodules occurring in non-cirrhotic livers, and for those cases with inconclusive or atypical imaging appearance in cirrhotic livers. 7. Non-invasive criteria can only be applied to cirrhotic patients and need to be based on imaging techniques obtained by 4-phase multidetector CT scan or dynamic contrast enhanced MRI and on the identification of the typical hallmark of HCC (hypervascular in the arterial phase with washout in the portal venous or delayed phase). One imaging technique is sufficient for nodules beyond 1 cm (\> 1 cm) in diameter. 8. Patients for whom no standard anti-tumour therapy is indicated for the next 3 months thereafter any standard anti-tumour therapies applied for the treatment of BCLC stage 0, A and B HCC (e.g. RFA/PEI, TACE, and SIRT) are allowed to be applied in combination with the study treatment. Patients for whom treatment for advanced disease (e.g. sorafenib) is indicated will be withdrawn from study treatment. 9. Eastern Cooperative Oncology Group (ECOG) performance status 0/1 with the specific characteristics indicated in the exclusion criteria. 10. Child-Pugh A5-6 and B7 disease or no liver function impairment. 11. Body weight \>30 kg. 12. Adequate normal organ and marrow function as defined below: 1. Haemoglobin ≥9.0 g/dL 2. Absolute neutrophil count (ANC) ≥1.0 × 109 /L 3. Platelet count ≥75 × 109 /L 4. Serum bilirubin ≤1.5 x institutional upper limit of normal (ULN). This will not apply to patients with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of haemolysis or hepatic pathology), who will be allowed only in consultation with their physician. 5. AST (SGOT)/ALT (SGPT) ≤5 x institutional upper limit of normal 6. Measured creatinine clearance (CL) \>40 mL/min or Calculated creatinine CL\>40 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance: Males: Creatinine CL (mL/min) = Weight (kg) x (140 - Age) 72 x serum creatinine (mg/dL) Females: Creatinine CL (mL/min) = Weight (kg) x (140 - Age) x 0.85 72 x serum creatinine (mg/dL) 13. Willingness and ability to comply with the study protocol for the duration of the study. 14. Female patient of child-bearing potential: * Female patients of childbearing potential who are not totally sexually abstinent (i.e., refraining from heterosexual intercourse during the entire period of risk associated with study interventions) and intend to be sexually active with a non sterilised male partner must use at least 1 highly effective method of contraception (Appendix 4). They should have been stable on their chosen method of birth control for a minimum of 3 months before entering the study and continue to use it throughout the total duration of the drug treatment and the drug washout period (90 days after the last dose of study treatment). Non sterilised male partners of a female patient of childbearing potential must use male condom plus spermicide throughout this period. Cessation of birth control after this point should be discussed with a responsible physician. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Female patients should also refrain from breastfeeding throughout this period. Male patients with a female partner of childbearing potential: * Non-sterilised male patients who are not abstinent and intend to be sexually active with a female partner of childbearing potential must use a male condom plus spermicide from the time of screening throughout the total duration of the drug treatment and the drug washout period (90 days after the last dose of study treatment). Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. Male patients should refrain from sperm donation throughout this period. Vasectomised males are considered fertile and should still use a male condom plus spermicide as indicated above during the clinical study. * Even if the female partner is pregnant, male participants should still use a condom plus spermicide (where approved), as indicated above during the clinical study, if there is a concern about damaging the developing foetus from drug in ejaculate. * Female partners (of childbearing potential) of male patients must also use a highly effective method of contraception throughout this period (Appendix 4). Exclusion Criteria: Patients should not enter the study if any of the following exclusion criteria are fulfilled: 1. Any prior systemic anti-tumour treatment (including drug or treatment regimen, approved or experimental) within 2 weeks before study treatment administration. 2. Major surgical procedure (as defined by the Investigator) within 28 days prior to the first dose of IP. Note: Local surgery of isolated lesions for palliative intent is acceptable 3. Liver transplanted patients; patients who are on the liver transplantation waiting list are not allowed to be enrolled. 4. Concurrent enrolment in another clinical study, unless it is an observational (non interventional) clinical study or during the follow-up period of an interventional study. 5. Any unresolved toxicity NCI CTCAE Grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria 1. Patients with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician. 2. Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study Physician. 6. History of allogenic organ transplantation. 7. History or evidence of systemic autoimmune disease, e.g. rheumatoid arthritis, multiple sclerosis, systemic lupus erythematosus (SLE), scleroderma, Sjögren's syndrome, Wegener's granulomatosis, Guillain-Barre syndrome. 8. Need for concomitant treatment with immunosuppressive drugs or other immune modifying drugs. The use of inhaled and nasally applied steroids, as well as topical steroids outside the vaccination area are permitted. 9. Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhoea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent. 10. History of other malignancies within the last 3 years except for adequately treated except cervical carcinoma in situ, basal cell carcinoma and superficial bladder tumours \[Ta, Tis \& T1\] or any cancer curatively treated \> 3 years prior to signing of informed consent by the patient. 11. History of leptomeningeal carcinomatosis. 12. Mean QT interval corrected for heart rate using Fridericia's formula (QTcF) ≥470 ms calculated from 3 ECGs (within 15 minutes at 5 minutes apart). Regardless of whether this criterion stays or not, all patients should have a baseline ECG. 13. Any medically diagnosed or suspected condition of immunodeficiency or medical history thereof 14. Known to have tested positive for human immunodeficiency virus (HIV) (positive HIV 1/2 antibodies) or active tuberculosis infection (clinical evaluation that may include clinical history, physical examination and radiographic findings, or tuberculosis testing in line with local practice). 15. Any other known infection with a biological agent that can cause a severe disease and poses a severe danger to lab personnel working on patients' blood or tissue. Examples are: rabies, Mycobacterium leprae, Plasmodium falciparum, Coccidioides immitis. 16. Acute and active infections requiring oral or intravenous antibiotics, antiviral or antifungal therapy within 30 days prior to enrolment (exception: Hepatitis B Virus (HBV) and/or Hepatitis C Virus (HCV) infections; direct-acting antivirals may be applied as medically indicated). 17. Receipt of live attenuated vaccine within 30 days prior to the first dose of IP. Note: Patients, if enrolled, should not receive live vaccine whilst receiving IP and up to 30 days after the last dose of IP. 18.
