Overview
Brief Summary
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.
Detailed Description
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.

Arms & Interventions
Pembrolizumab via localized infusion
This group dividied into two subgroups: 1. Checkpoint inhibitor (CPI) such as Pembrolizumab ± Ipilimumab is administrated with a dose of 1-2mg/kg via sustained (10min) micro-pump infusion via artery, plus chemotherapy, every 3 weeks. 2. Checkpoint inhibitor (CPI) such as Pembrolizumab ± Ipilimumab is administrated with a total dose of 150mg via intra-tumor fine needle injection in 5 min, plus doxorubicin, every 3 weeks.
Intervention: Checkpoint inhibitor (CPI) such as Pembrolizumab plus chemotherapy
Checkpoint inhibitor (CPI) Pembrolizumab plus chemotherapy via vein infusion
Checkpoint inhibitor (CPI) such as Pembrolizumab is administrated with a total dose of 2mg/kg via vein infusion (30 min), plus chemotherpy every 3 weeks.
Intervention: Checkpoint inhibitor (CPI) such as Pembrolizumab plus chemotherapy
Outcomes
Primary Outcomes
Overall survival
Time Frame: 5 years
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.
Complete response (CR) rate before or at Month 6
Time Frame: 4
Percentage of patients achieving complete response (CR) before or at Month 6

- Disease control rate(5 years)
- Progression-free survival(5 years)
- Duration of remission (DOR)(5 years)
- Cause of death (COD) when appropriate(5)
