HAIC Combined With Camrelizumab and TKI for Unresectable Hepatocellular Carcinoma After TACE Failure

Hepatic Artery Infusion Chemotherapy (HAIC) Combined With Camrelizumab and Tyrosine Kinase Inhibitor for Unresectable Hepatocellular Carcinoma After Transcatheter Arterial Chemoembolization (TACE) Failure: a Single-arm and Open-label Prospective Study

The efficacy and safety of HAIC combined with tyrosine kinase inhibitor and immunotherapy have been proved by the clinical research. In this single-arm, open-label, prospective study, for those patients with unresectable primary HCC, in the case of failure of TACE treatment, the combination of HAIC, TKI and immunotherapy is expected to bring new breakthroughs.

Inclusion Criteria:

5. BCLC B and C
6. TACE failure: ① Even if chemotherapeutic drugs are changed or the blood supply artery is reassessed, CT/MRI examinations after 2 consecutive TACE treatments 1-3 months show that the target lesions in the liver are compared with the previous TACE count. There are still more than 50% remaining or new lesions; ② extrahepatic metastasis or vascular invasion; ③ postoperative tumor indicators continue to rise (even if there is a short-term decline)
7. ECOG 0-1
8. The expected survival is more than 3 months
9. The function of vital organs is normal (no blood components, cell growth factor drugs are allowed to be used within 14 days before the first medication)
10. Women of childbearing age need contraception

Exclusion Criteria:

1. The patient has any active autoimmune disease or a history of autoimmune disease

3. Patients who have progressed after receiving second-line or above anti-vascular drug therapy in the past, or patients who have received immunotherapeutic drugs such as PD-1 / PD-L1 monoclonal antibody
4. Have received HAIC treatment in the past
5. Severe allergic reaction to other monoclonal antibodies
6. People with known history of central nervous system metastasis or hepatic encephalopathy
7. Patients whose liver tumor burden is greater than 50% of the total liver volume, or who have received liver transplantation in the past
8. Ascites with clinical symptoms, those who need puncture, drainage, or those who have received ascites drainage within the past 3 months, except for those with only a small amount of ascites on imaging but no clinical symptoms
9. Suffer from high blood pressure and cannot be well controlled by antihypertensive drugs (systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg)
10. Have uncontrolled clinical symptoms or diseases of the heart
