Korábbi kezelés

• Patients with contraindications to ablation or atezolizumab or bevacizumab
• Prior liver transplantation
• Current or recent (≤10 days prior to initiation of study treatment) use of aspirin (\> 325 mg/day) or treatment with clopidogrel, dipyramidole, ticlopidine, or cilostazol.
• Treatment with systemic immunosuppressive medication (including, but not limited to, corticosteroids, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-TNF-α agents) within 2 weeks prior to initiation of study treatment, or anticipation of need forsystemic immunosuppressive medication during study treatment, with the following exceptions:
  • Patients who received acute, low-dose systemic immunosuppressant medication or a onetime pulse dose of systemic immunosuppressant medication (e.g., 48 hours of corticosteroids for a contrast allergy) are eligible for the study after Medical Monitor confirmation has been obtained.
  • Patients who received mineralocorticoids (e.g., fludrocortisone), corticosteroids for chronic obstructive pulmonary disease (COPD) or asthma, or low-dose corticosteroids for orthostatic hypotension or adrenal insufficiency are eligible for the study.
• Prior chemo-embolization or radio-embolization.
• Patients with extra-hepatic metastases, either previously-treated or not. One lung nodule (\<5mm) is allowed. Calcified lung micronodules as well as typical intra-pulmonary lymph nodes are allowed. Hepatic hilum lymph node \< 10mm (short axis) is allowed.
• Prior surgery of HCC with micro- or macro-vascular invasion demonstrated at pathology.
• Untreated or incompletely treated esophageal and/or gastric varices with bleeding or high risk for bleeding. Patients must undergo an esophagogastroduodenoscopy (EGD), and all size of varices (small to large) must be assessed and treated per local standard of care prior to enrollment. Patients who have undergone an EGD within 6 months of prior to initiation of study treatment do not need to repeat the procedure
• Past or concurrent history of neoplasm other than HCC, except for in-situ carcinoma of the cervix uteri and/or non-melanoma skin cancer and superficial bladder tumors. Any cancer curatively treated \> 3 years prior to study entry is permitted
• Clinically significant bleeding NCI-CTCAE version 5.0 ≥ Grade 3 within 30 days before enrolment (transfusion indicated)
• Arterial or venous thrombotic or embolic events such as cerebrovascular accident, deep vein thrombosis or pulmonary embolism within 6 months before enrolment

  • Rash must cover \< 10% of body surface area.
  • Disease is well controlled at baseline and requires only low-potency topical corticosteroids.
  • No occurrence of acute exacerbations of the underlying condition requiring psoralen plus ultraviolet A radiation, methotrexate, retinoids, biologic agents, oral calcineurin inhibitors, or high-potency or oral corticosteroids.
• Patients with uncontrolled HBV infection and viral load above 500 IU/mL.
• Grade 3 (severe) hypertension ≥160 and/or ≥100 mmHG (systolic and diastolic, according to NCI-CTCAE v5.0)
• Ongoing infection : Hepatitis B is allowed if no active replication is present (HBV replication below 500 IU/mL) or Hepatitis C is allowed if no antiviral treatment is required
• Any psychological, familial, sociological, geographical or illness or medical condition that could jeopardize the safety of the patient and/or his compliance with the study protocol and follow-up procedure
• Known history of human immunodeficiency virus (HIV) infection

• Non-healing wound, ulcer or bone fracture

Laborértékek

• Current or recent (≤ 10 days prior to initiation of study treatment) use of full-dose oral or parenteral anticoagulants or thrombolytic agents for therapeutic (as opposed to prophylactic) purpose. Prophylactic anticoagulation for the patency of venous access devices is allowed provided the activity of the agent results in an INR \< 1.5 x ULN and aPTT is within normal limits within 14 days prior to initiation of study treatment. For prophylactic use of anticoagulants or thrombolytic therapies, the approved dose as described by local label may be used.
• Prior systemic treatment for HCC, in particular agents targeting T-cell costimulation or checkpoint pathways (including those targeting PD-1, PD-L1 or PD-L2, cluster of differentiation 137 (CD137), or cytotoxic T-lymphocyte antigen (CTLA-4)).
