This trial was designed to investigate the safety, response rates and survival outcomes of patients with advanced solid tumors by trans-artery/intra-tumor infusion of PD1/PDL1 antibody and/or CTLA4 antibody ipilimumab plus chemotherapeutic drug and to compare their differences.
Malignant solid tumors including lung and liver cancers are the most common malignancy worldwide, and their mortality rates are very high. China has a huge population base, with about 4,000,000 new cases each year. More than 60% of the solid tumors in China are diagnosed at mid-to-late stage and have lost the chance of surgery. Recently a lot of therapeutic strategies have been developed and applied to clinic including targeted therapy and immunotherapy, but the overall efficiency is still low. It is difficult to be widely used in patients with advanced solid cancers, and more alternative therapies are urgently needed. Antibodies against PD1, PDL1 and CTLA4 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 in the tumor, improve the efficacy, and reduce systemic adverse reactions, through so called "first pass effect" of drug on target organs. To the investigator's knowledge, no studies have been developed on the efficacy and survival benefit of localized delivery of checkpoint inhibitors for treatment of cancer patients. This phase II-III clinical trial was designed to compare the effects of Pembrolizumab, Tecentriq, et al and/or ipilimumab plus chemotherapeutic drug such as doxorubicin on the survival benefit of patients with advanced solid cancers, including ORR, DCR, median survival time, and safety.

RECRUITINGOverall 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
Complete response (CR) rate before or at Month 6
Percentage of patients achieving complete response (CR) before or at Month 6
Time frame: 4
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 mRECIST) 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
Duration of remission (DOR)
DOR will be defined as the duration of the cancer remission
Time frame: 5 years
Disease control rate
Disease control rate will be defined as objective response rate + steady disease rate.
Time frame: 5 years
Cause of death (COD) when appropriate
