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 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 of 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 on the survival benefit of patients with advanced solid cancers, including ORR, DCR, median survival time, and safety.
