• Subjects refuse to provide tumor biopsy specimens within 4 weeks before registration
• Concomitant anticoagulation, at therapeutic doses, with anticoagulants such as warfarin or warfarin-related agents, low molecular weight heparin (LMWH), thrombin or coagulation factor X (FXa) inhibitors.
  • (Note: Low dose aspirin for cardioprotection (per local applicable guidelines), low-dose warfarin (≤ 1 mg/day), and low dose LMWH (e.g. 40 mg Enoxaparin) for prophylaxis of venous thromboembolism are permitted)
• Major surgery within 2 months before registration. Complete healing from major surgery must have occurred 1 month before registration. Complete healing from minor surgery (e.g., simple excision, tooth extraction) must have occurred at least 7 days before registration
• Clinically significant bleeding risk including the following within 3 months before registration: upper GI bleeding (including gastroesophageal varices bleeding), hematuria, hemoptysis of >0.5 teaspoon (>2.5 mL) of red blood, or other signs indicative of pulmonary hemorrhage, or history of other significant bleeding if not due to reversible external factors
• Previously identified allergy or hypersensitivity to components of the study treatment formulations
• Diagnosis of another malignancy within 2 years before registration, except for superficial skin cancers, or localized, low-grade tumors deemed cured and not treated with systemic therapy

  • Stroke (including transient ischemic attack), myocardial infarction, or other ischemic event within 6 months
  • Thromboembolic event within 3 months. (Note: Subjects with thromboses of portal/hepatic vasculature attributed to underlying liver disease and/or liver tumour are eligible)
  • Gastrointestinal (GI) disorders including those associated with a high risk of perforation or fistula formation/bleeding:
  • Tumours invading the GI tract, inflammatory bowel disease, diverticulitis, cholecystitis, symptomatic cholangitis or appendicitis, acute pancreatitis or acute obstruction of the pancreatic duct or common bile duct, or gastric outlet obstruction
  • Abdominal fistula, GI perforation, bowel obstruction, intra-abdominal abscess within 6 months
• Other clinically significant disorders that are judged by investigators to be unsuitable for the clinical trial

Laborértékek

• Corrected QT interval calculated by the Fridericia formula (QTcF) > 500 ms within 4weeks before registration (Note: If the QTcF is > 500 ms in first ECG, a total of 3 ECGs should be performed. If the average of these 3 consecutive results for QTcF is ≤ 500 ms, the subject meets eligibility)

Egyéb

• Understood and signed the informed consent form
• Ability to comply with all protocol requirements
• Age ≥ 18 years when signing informed consent form
• Diagnosis of HCC confirmed by histology
• Disease progression following prior first-line ICI-based combination therapy (only atezolizumab plus bevacizumab or tremelimumab plus durvalumab is permitted. Any liver-directed locoregional therapies administered during the treatment period of the first-line ICI-based combination therapy are allowed.
• Disease that is not amenable to curative surgical and/or locoregional therapies (e.g. surgery, transplant, radiofrequency ablation)
• At least one measurable target lesion (per RECIST v1.1) that has not been previously treated with local therapy (e.g., radiofrequency ablation, cryoablation, transarterial embolization, transaraterial chemoembolization, radiotherapy, etc.) or, if the target lesion is within the field of previous local therapy, has subsequently progressed in accordance with RECIST v1.1.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
• Child-Pugh A of liver reserve
• Adequate hematologic and biochemical profiles:
