Brief Summary

Study introduction: this is a multicenter, randomized controlled study of patients with histopathologically confirmed hepatocellular carcinoma (HCC) who have not previously received systematic treatment for HCC, all the patients are Chinese stage IIb/IIIa (BCLC stage B/C), and have not developed extrahepatic metastases. Follow-up, data collection and analysis will be performed for patients who meet the study inclusion criteria and will be treated with lenvatinib plus toripalimab and TACE (on demand) or TACE alone, so as to compare the objective response rate (ORR), overall survival (OS), progression-free survival (PFS), ratio of conversion resection, and safety between the two cohorts.

Detailed Description

The study includes two groups:

Treatment group: patients with potentially resectable HCC who meet the study inclusion criteria will be treated with lenvatinib in combination with toripalimab and TACE (on demand). Tumor response will be regularly evaluated, data will be collected, and complete surgical resection will be evaluated by an independent review committee, the conversion resection rate will be calculated, and patient survival will be assessed.

Control group: patients with potentially resectable HCC who meet the study inclusion criteria will be treated with TACE. Tumor response will be regularly evaluated, data will be collected, and complete surgical resection will be evaluated by an independent review committee, the translational resection rate will be calculated, and patient survival will be assessed.

The maximum duration of study treatment for each subject is expected to be 48 weeks, with efficacy evaluation by the MDT after 2 TACE treatments to determine whether subjects meet the surgical criteria.

This study is a multicenter, randomized controlled study. The primary endpoint is the objective response rate (ORR). Historical data showed that the objective response rate of patients in the TACE group was about 40%. The objective response rate of lenvatinib in combination with toripalimab and TACE is expected to reach 60%. Using a two-sided Z test of pooled variance, α is set to 0.05, power is set to 0.8, and patients will be assigned at a 1:1 ratio. The required sample sizes are 98 (treatment group) and 98 (control group), and a total of 220 subjects are planned to be prospectively observed, taking into account a dropout rate of 10%.

Study Groups

Treatment group

Patients with potentially resectable HCC who meet the study inclusion criteria will be treated with lenvatinib(8mg/d for BW\<60kg and 12mg for BW≥60kg) in combination with toripalimab(240mg iv Q3W) and TACE (on demand). Tumor response will be regularly evaluated, data will be collected, and complete surgical resection will be evaluated by an independent review committee, the conversion resection rate will be calculated, and patient survival will be assessed.

Eligibility Criteria

Inclusion Criteria

1. Male or female patients of 18-75 years old;

2. Clinical or histopathological diagnosis of hepatocellular carcinoma;

3. ECOG PS score of 0-1, Child-Pugh grade A;

4. Chinese stage IIb/IIIa (equal to BCLC B/C) patients with portal vein tumor thrombus (according to the Japanese PVTT grading criteria Vp3-Vp4) or more than 3 tumor nodules, without extrahepatic metastasis;

5. According to the evaluation by the site multi-disciplinary team (MDT), surgical resection is not the current preferred treatment;

6. No previous systemic treatment for hepatocellular carcinoma; no previous use of PD-1 inhibitor, PD-L1 inhibitor, lenvatinib or sorafenib;

7. Previous TACE treatment for 0-2 times

8. The patients in the treatment group voluntarily and have decided to receive treatment of lenvatinib in combination with toripalimab and TACE, and sign an informed consent form. Additional identification of qualified subjects: subjects who have received at least one combination medication enter the safety evaluation; subjects who have received at least one imaging evaluation after treatment enter the efficacy evaluation. The patients in the control group treated with TACE alone have at least one imaging evaluation.

9. Patients with HBV infection (characterized by hepatitis B surface antigen [HBsAg] positive and/or hepatitis B core antibody [anti-HBcAb], with detectable HBV DNA [>10 IU/mL]) should be treated with antiviral therapy according to clinical routine, so as to ensure adequate viral suppression (HBV DNA≤2000 IU/mL or 104) before enrollment. Patients must maintain antiviral therapy during the study period and within 6 months after the last study drug administration; patients with positive hepatitis B core antibody (HBc) and undetectable HBV DNA (<10 IU/mL) will be not required to receive antiviral therapy before enrollment; these patients will be checked every cycle to monitor HBV DNA levels; if HBV DNA is detected (> 10 IU/mL), antiviral therapy will be initiated; patients with detectable HBV DNA must continue to receive antiviral therapy during the study
