Who can take part

You may be able to join if

1. Participant must be ≥ 18 years (and above legal age) at the time of screening.
12. Body weight of > 30 kg.
13. Male or female.
9. Participants with HBV infection (as characterised by positive HbsAg and/or anti-HBcAb with detectable HBV DNA, as per local laboratory standards) must be treated with antiviral therapy, as per institutional practice, to ensure adequate viral suppression (as per local laboratory standards) prior to enrolment. Participants must remain on antiviral therapy for the study duration and for 6 months after the last dose of study intervention. Participants who test positive for anti-HBc with undetectable HBV DNA (as per local laboratory standards) do not require antiviral therapy prior to enrolment. These participants will be tested at every cycle to monitor HBV DNA levels and initiate antiviral therapy if HBV DNA is detected (as per local laboratory standards). HBV DNA detectable participants must initiate and remain on antiviral therapy for the study duration and for 6 months after the last dose of study intervention.
11. Adequate organ and marrow function, as defined below. Criteria “a”, “b”, “c”, and “f” cannot be met with transfusions, infusions, or growth factor support administered within 14 days of starting the first dose. (a) Haemoglobin ≥ 7.5 g/dL. Participants with 7.5 g/dL < haemoglobin < 9.0 g/dL having active or chronic bleeding to be excluded. (b) Absolute neutrophil count ≥ 1000/μL. (c) Platelet count ≥ 60000/μL. Participants with 60000 μL < platelets count < 75000 μL having active or chronic bleeding to be excluded. (d) TBL ≤ 3 × the ULN. (e) ALT and AST ≤ 5 × ULN. (f) Albumin ≥ 2.6 g/dL. (g) INR < 2.3. (h) Calculated CrCL > 40 mL/min as determined by Cockcroft-Gault (using actual body weight) or creatinine clearance assessed by the method used as per institutional guidance. Males: CrCL (mL/min) = Weight (kg) × (140 - Age) / 72 × serum creatinine (mg/dL) Females: CrCL (mL/min) = Weight (kg) × (140 - Age) × 0.85 / 72 × serum creatinine (mg/dL)
10. Participants with HCV infection must have confirmed diagnosis of HCV characterised by the presence of detectable HCV RNA or anti-HCV upon enrolment (management of this disease is per local institutional practice).

You likely can't join if

1. As judged by the investigator, any evidence of diseases (such as severe or uncontrolled systemic diseases, including active COVID-19, uncontrolled hypertension, active bleeding diseases, active infection, active interstitial lung disease/pneumonitis, serious chronic GI conditions associated with diarrhoea, psychiatric illness/social situations) chronic diverticulitis or previous complicated diverticulitis, or history of allogeneic organ transplant (eg, liver transplant), which, in the investigator’s opinion, makes it undesirable for the participant to participate in the study or that would jeopardise compliance with the protocol.
4. History of another primary malignancy except for: (a) Malignancy treated with curative intent with no known active disease ≥ 2 years before the first dose of study intervention and of low potential risk for recurrence. (b) Basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or lentigo maligna that has undergone potentially curative therapy. (c) Adequately treated carcinoma in situ without evidence of disease.
7. History of active primary immunodeficiency.
28. No liver biopsy should have been performed within 2 weeks of the first dose of study intervention.
29. Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site).
30. Judgement by the investigator that the participant should not participate in the study if the participant is unlikely to comply with study procedures, restrictions, and requirements.

10. Participants with HCV infection must have confirmed diagnosis of HCV characterised by the presence of detectable HCV RNA or anti-HCV upon enrolment (management of this disease is per local institutional practice).
2. Confirmed unresectable HCC based on histopathological findings (prior histological verification confirming HCC is acceptable), or radiological findings in participants with cirrhosis where histopathological confirmation is not clinically feasible. - In participants with cirrhosis, HCC radiological diagnosis following the American Association for the Study of the Liver Diseases guidance may be used if histological confirmation is not clinically feasible by fresh or archival tissue: o CT is preferred over MRI in participants with large ascites or those with difficulty holding breath. o In participants with renal disease or iodine allergy, MRI may be preferred. o In participants with hepatic decompensation (TBL > 2 to 3 mg/dL), hepatobiliary contrast agents uptake by the liver tends to be reduced, in which case, extracellular contrast agents may be preferred.
16. Male participants who intend to be sexually active with a female partner of childbearing potential must be surgically sterile or using an acceptable method of contraception from the time of screening throughout the total duration of the study and the drug washout period (90 days after the last dose of durvalumab and tremelimumab combination therapy or 90 days after the last dose of durvalumab monotherapy) to prevent pregnancy in a partner. Male participants must not donate or bank sperm during this same time period. (a) Female partners (of childbearing potential) of male participants must also use a highly effective method of contraception throughout this period.
17. Capable of giving signed informed consent.
18. Written informed consent from the participant has been obtained prior to any study-related procedures.
3. Must not have received prior systemic therapy for HCC.
4. Participants expected to live 12 weeks or more.
5. At least 1 measurable lesion, not previously irradiated, that can be accurately measured at baseline as ≥ 10 mm in the longest diameter (except lymph nodes, which must have a short axis ≥ 15 mm) with CT or MRI, and that is suitable for accurate repeated measurements as per RECIST 1.1 guidelines. A lesion which progressed after previous ablation or transarterial embolisation procedures with or without radiation or chemotherapy could be measurable if it meets these criteria.
6. Must not be eligible for LRT for unresectable HCC. For participants who progressed after LRT for HCC, LRT must have been completed ≥ 28 days prior to the baseline scan for the current study.
14. Negative pregnancy test (serum) for women of childbearing potential.
15. Female participants must be 1 year post-menopausal (amenorrhoeic for 12 months without an alternative medical cause), surgically sterile, or using one highly effective form of birth control (a highly effective method of contraception is defined as one that can achieve a failure rate of less than 1% per year when used consistently and correctly). Women of childbearing potential must agree to use one highly effective method of birth control. They should have been stable on their chosen method of birth control for a minimum of 3 months before entering the study and from the time of screening throughout the total duration of the study and the drug washout period (90 days after the last dose of durvalumab and tremelimumab combination therapy or 90 days after the last dose of durvalumab monotherapy). Females receiving HRT and whose menopausal status is in doubt will be required to use one of the contraception methods outlined for FOCBP if they wish to continue using HRT during the study. Otherwise, HRT must be discontinued to allow confirmation of postmenopausal status prior to randomization. (a) Non sterilised male partners of a woman of childbearing potential must use a male condom plus spermicide (condom alone in countries where spermicides are not approved) throughout this period. Cessation of birth control after this point should be discussed with a responsible physician. Periodic abstinence, as well as the rhythm and withdrawal methods are not acceptable methods of birth control.
7. BCLC stage B (that is not eligible for LRT) or stage C.
8. Child-Pugh Score classification on liver disease (refer to Section 8.2.7 of the protocol) and WHO/ECOG PS (refer to Section 8.2.6 of the protocol) at enrolment must comply with one of the following criteria, not cumulatively: (a) Child-Pugh score B7 or B8 with a WHO/ECOG PS of 0-1 at enrolment, without main trunk portal vein thrombosis. (b) Child-Pugh class A with a WHO/ECOG PS of 2 at enrolment, without main trunk portal vein thrombosis (ie, ECOG PS 2 participants with main portal vein tumour thrombosis are excluded from this study). (c) Child-Pugh class A with WHO/ECOG PS of 0-1 at enrolment and with chronic main trunk portal vein thrombosis, based on investigators’ clinical judgement (participants with acute main trunk portal vein thrombosis are excluded from this study).
