Camrelizumab Combined With Apatinib Mesylate for Perioperative Treatment of Resectable Hepatocellular Carcinoma：a Randomized, Open-label, Parallel, Multicenter Trial

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 (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. One cycle of postoperative TACE treatment is allowed in both experimental and control group. The primary purpose of this study is to evaluate the rate of subjects with major pathological response for phase 2 study and event-free survival (EFS) by investigator for phase 3 study of camrelizumab combined with apatinib mesylate in the perioperative period of HCC. The secondary research purpose is to evaluate the EFS by Blinded Independent Review Committee, the R0 resection rate, the rate of subjects with major pathological response, the rate of subjects with pathological complete response, overall survival and disease-free survival of camrelizumab combined with apatinib mesylate in the perioperative period of resectable HCC. The safety and tolerability is also evaluated.
