TACE Combined With Sorafenib and PD-1 mAb in the Treatment of BCLC B/C Hepatocellular Carcinoma: Single Arm, Single Center, Open Label Study

GXu

Hepatocellular carcinoma (HCC) is the fourth most common cause of cancer-related death that ranks sixth in terms of incident cases, with an overall 5 years survival of 18%. Despite a significant improvement in treatment strategy, the overall survival of HCC remains low due to high recurrence, progressive liver dysfunction and the high fatality of the disease. Surgical resection has been applied in a number of patients; however, surgery has been associated with a high incidence of recurrence (approximately 70% within 5 years). TACE is generally applied on intermediate-stage HCC. However, TACE is not satisfied with improving overall survival. Therefore, there is an urgent need for effective treatment for these patients. At present, the overall objective response rate (ORR) of single or sequential therapy is not satisfied, and the over survival (OS) improvement is not ideal. Therefore, combined therapy maybe the good choice for patients with advanced HCC. This study focuses on the in-operable, BCLC-B/C HCC patients. Through the combination of local therapy (TACE), anti-angiogenic therapy (Sorafenib), and immunotherapy (PD-1 monoclonal antibody), it is expected to change the tumor microenvironment, restore the immune response, strengthen the anti-tumor effect of various treatments, and improve the therapeutic efficacy in patients with BCLC-B/C HCC.

Inclusion Criteria: 1. Histopathologically or clinically confirmed hepatocellular carcinoma. 2. Age ≥ 18 years old. 3. Performance status (PS) ≤ 2 (ECOG scale). 4. Barcelona clinical liver cancer (BCLC) stage B or stage C. 5. Participants who have not received other systemic anti-tumor treatment for HCC before the first administration. 6. Patients who had not received TACE before the first administration, or who had received 0-2 times TACE but PD or SD ≥ 4 weeks. 7. According to mRECIST, there is at least one measurable lesion. 8. Child Pugh score ≤ 7. 9. Participant has sufficient organ and marrow functions. 10. Expected survival time ≥ 12 weeks. 11. For women of childbearing age or male patients whose sexual partners are women of childbearing age, effective contraceptive measures should be taken during the whole treatment period and 6 months after the last medication. 12. Sign the written informed consent, and be able to follow the visit and relevant procedures specified in the plan Exclusion Criteria: 1. Fibrolamellar carcinoma, sarcomatoid carcinoma, cholangiocarcinoma and other components previously confirmed by histology / cytology. 2. History of hepatic encephalopathy or liver transplantation. 3. Pleural effusion, ascites and pericardial effusion with clinical symptoms requiring drainage. 4. Tumor burden≥70%, diffuse liver cancer or tumor is not suitable for mRECIST standard evaluation. 5. Received local treatment (ablation therapy), surgery resection and radiotherapy for liver cancer before the first administration. 6. Have received systemic chemotherapy, targeted therapy or immunotherapy 7. There is a significant decrease in white blood cells and platelets in peripheral blood, severe coagulation dysfunction and can not be corrected：the neutrophil\<1.5×109/L, PLT\<50×109/L. The INR\>2.3 8. Acute or chronic active hepatitis B or C infection, hepatitis B virus (HBV-DNA) \> 10\^6 copies / ml; hepatitis C virus (HCV-RNA) \> 10\^3 copies / ml; HBsAg and anti HCV antibody were positive at the same time. 9. There is central nervous system metastasis. 10. Bleeding of esophageal or gastric varices caused by portal hypertension occurred in the past 6 months, or severe (G3) varices were found in endoscopic examination within 3 months before the first administration, or evidence of portal hypertension (including splenomegaly found in imaging examination) was found. The researchers assessed that the risk of bleeding was high and did not receive sclerotherapy or ligation under the endoscope. 11. The previous 6-month history of arteriovenous thromboembolism, including myocardial infarction, unstable angina, cerebrovascular accident, pulmonary embolism, deep vein thrombosis or any other serious thromboembolism. The thrombus of implanted vein port or catheter source or superficial vein is stable after routine anticoagulant treatment. Prophylactic use of low- molecular-weight heparin (e.g., enoxaparin 40 mg / day) is permitted. 12. Tumor thrombus of main portal vein, or involving superior mesenteric vein at the same time. 13. Aspirin (\> 325 mg / day) or other drugs known to inhibit platelet function such as dipyridamole or clopidogrel were used for 7 consecutive days within 2 weeks before the first administration. 14. For uncontrolled hypertension, systolic blood pressure \> 150 mmHg or diastolic blood pressure \> 100 mmHg after the best medical treatment, hypertension crisis or hypertension encephalopathy history. 15. Symptomatic congestive heart failure (New York Heart Association class II-IV). Symptomatic or poorly controlled arrhythmias. The corrected QT interval (QTc) for the history or screening of congenital long QT syndrome was more than 500 ms (calculated by Fridericia method). 16. Serious bleeding tendency or coagulation dysfunction, or undergoing thrombolysis. 17. In the past 6 months, there was a history of gastrointestinal perforation and / or fistula, a history of intestinal obstruction (including incomplete intestinal obstruction requiring parenteral nutrition), extensive enterotomy (partial colectomy or extensive enterotomy with chronic diarrhea), Crohn's disease, ulcerative colitis or long-term chronic diarrhea. 18. Previous and current pulmonary fibrosis history, interstitial pneumonia, pneumoconiosis, drug-related pneumonia, severe impairment of lung function and other lung diseases. 19. Active tuberculosis (TB), who is receiving anti TB treatment or has received anti TB treatment within one year before the first administration. 20. People with HIV infection (HIV 1 / 2 antibody positive) and known syphilis infection. Serious infection in active stage or poor clinical control. 21. Severe infection within 4 weeks before the first administration, including but not limited to hospitalization due to complications of infection, bacteremia or severe pneumonia. 22. Active autoimmune diseases requiring systemic treatment (such as the use of disease alleviation drugs, corticosteroids or immunosuppressants) occurred within 2 years before the first administration. Alternative therapies (e.g. thyroxine, insulin, or physiological corticosteroids for adrenal or pituitary insufficiency) are permitted. Known history of primary immunodeficiency. Only the patients with positive autoimmune antibody need to confirm whether there is autoimmune disease according to the judgment of researchers. 23. Immunosuppressive drugs were used within 4 weeks before the first administration, excluding local glucocorticoids or systemic glucocorticoids (i.e. no more than 10 Mg / day prednisone or the equivalent dose of other glucocorticoids), allowing temporary use of glucocorticoids due to dyspnea symptoms in the treatment of asthma, chronic obstructive pulmonary disease and other diseases. 24.
