This trial is designed to investigate the safety, response rates and survival outcomes of patients with hepatocellular carcinoma by infusion of CTLA4, PD1 and PDL1 antibodies combination with chemodrug or/and bevacizumab through intra-tumor (IT).
Antibodies against CTLA4, PD1 and PDL1 are representative drugs for the check-points inhibitory agents, and their clinical indications have been approved in various types of tumors, including advanced melanoma, non-small cell lung cancer, renal cell carcinoma, and classical Hodgkin's lymphoma and late recurrent head and neck squamous cell carcinoma patients, et al. Those drugs are regularly systemically administrated by vein infusion, however, local delivery of those drugs via interventional radiology technique including trans-artery or intra-tumor injection may increase the local drug concentration of the tumor, improve the efficacy, and reduce systemic adverse reactions. CTLA4 antibody ipilimumab has been widely effectively using to combine with PD1 or PDL1 antibody and this study is to combine ipilimumab and PD1 antibody or PDL1 antibody, so called double checkpoint inhibitors combination therapy, as first line for hepatocellular carcinoma (HCC) via intra-tumor admistration. To the investigator's knowledge, no studies have been developed on the safety, efficacy and survival benefit of the double checkpoint inhibitors combination therapy for cancer patients as first line via intra-tumor delivery. This phase II clinical trial is designed to assess the safety and survival benefit of ipilimumab and pembrolizumab or durvalumab combination with or without chemodrug or bevacizumab as first line therapy on patients with HCC, including PFS, ORR, DCR, and median survival time.

This study has 3 subgroups: Arm 1. Ipilimumab +pembrolizumab or Ipilimumab +durvalumab is administrated with a total dose of 1-2mg/kg via intra-tumor fine needle injection in 10 min, every 3 weeks. Arm 2. Ipilimumab +pembrolizumab or Ipilimumab +durvalumab combined with idarubicin is administrated via intra-tumor fine needle injection in 15 min, every 3 weeks. Arm 3. Ipilimumab +pembrolizumab or Ipilimumab +durvalumab combined with idarubicin plus bevacizumab is administrated via intra-tumor fine needle injection in 20 min, every 3 weeks.

RECRUITINGSafety of IT delivery of drugs combination treatment
Safety will be assessed by recording all types of advise effects upon and after the treatment.
Time frame: 5 years
Progression-free survival
Progression-free survival (PFS) will be defined as the elapsed time from the first date of study treatment until documented disease progression (as per RECIST 1.1) or death from any cause, whichever is earlier. For patients who remain alive without progression, follow-up time will be censored at the date of last disease assessment.
Time frame: 5 years
Disease control rate
Disease control rate will be defined as objective response rate + steady disease rate.
Time frame: 5 years
Duration of remission (DOR)
DOR will be defined as the duration of the cancer remission.
Time frame: 5 years
Overall survival
Overall survival (OS) will be defined as the elapsed time from the enrollment to death from any cause. For surviving patients, follow-up will be censored at the date of last contact (or last date known to be alive). Follow-up for OS will occur every 12 weeks (±1 month) until death or withdrawal of consent from the study.
Time frame: 5 years
