Overview
Hepatocellular carcinoma (HCC) is the most common primary liver cancer. Hepatectomy is a curable and effective method. However, the recurrence rate is as high as 50%~70% in 5 years after surgery. Perioperative treatment with immunotherapy combined with target therapy is expected to improve the patient's prognosis. This study aims to evaluate the efficacy, safety and tolerability of camrelizumab combined with apatinib mesylate in the perioperative period of resectable hepatocellular carcinoma. The primary purpose of this study is to evaluate 2 year event-free survival（2y-EFS） of camrelizumab combined with apatinib mesylate in the perioperative period of hepatocellular carcinoma (CNLC Ib-IIIa). The secondary research purpose is to evaluate the R0 resection rate, the rate of subjects with major pathological response, the rate of subjects with pathological complete response, event-free survival (EFS) and overall survival of camrelizumab combined with apatinib mesylate in the perioperative period of resectable hepatocellular carcinoma. The safety and tolerability is also evaluated.
Description
Hepatocellular carcinoma (HCC) is the most common primary liver cancer. Hepatectomy is a curable and effective method. However, the recurrence rate is as high as 50%~70% in 5 years after surgery. Perioperative treatment with immunotherapy combined with target therapy is expected to improve the patient's prognosis. This study aims to evaluate the efficacy, safety and tolerability of camrelizumab combined with apatinib mesylate in the perioperative period of resectable hepatocellular carcinoma. This trial includes subjects with CNLC Ib/IIa/IIb/IIIa HCC. All eligible subjects will be randomized (1:1) to experimental group or control group. In the experimental group, patients will be treated with following: neoadjuvant therapy ( perioperative TACE treatment，camrelizumab and apatinib, 2 cycles), radical surgery, adjuvant therapy (camrelizumab and apatinib, 6 cycles); in the control group, patients will be treated with following: radical surgery,adjuvant therapy (camrelizumab and apatinib, 6 cycles). The primary purpose of this study is to evaluate 2 year event-free survival（2y-EFS） of camrelizumab combined with apatinib mesylate in the perioperative period of hepatocellular carcinoma (CNLC Ib-IIIa). The secondary research purpose is to evaluate the R0 resection rate, the rate of subjects with major pathological response, the rate of subjects with pathological complete response, event-free survival (EFS) and overall survival of camrelizumab combined with apatinib mesylate in the perioperative period of resectable hepatocellular carcinoma. The safety and tolerability is also evaluated.
