Combination therapy using checkpoint inhibitors for advanced solid tumors

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This trial investigates the safety and effectiveness of a combination therapy using CTLA4, PD1, and PDL1 antibodies for patients with advanced solid tumors, including lung, liver, colorectal, pancreas, and ovary cancers. The treatment is administered through various methods, including intravenous, intra-arterial, or intra-tumor infusion, aiming to enhance local drug concentration and reduce systemic side effects. The study is particularly relevant given the high mortality rates associated with these cancers and the urgent need for alternative therapies in patients with recurrent or metastatic disease.
