Study start date: September 16, 2024

Actual date on which the first participant was enrolled.

This clinical trial focuses on testing a new treatment called VET3-TGI for people with advanced solid tumors. The study aims to find out the safest and most effective dose of VET3-TGI when given alone or alongside another drug called pembrolizumab. VET3-TGI is specially designed in the lab to target and destroy cancer cells while sparing healthy ones. This new approach is important because it could offer a new way to treat cancers that have not responded well to other treatments. Participants in the study receive VET3-TGI either through direct injection into their tumors or by intravenous infusion. The study involves several groups to determine how much of VET3-TGI can be safely given on its own and in combination with pembrolizumab. Once the best dose is identified, more patients may receive that dose to further assess how well it works. This approach helps ensure that the treatment is both safe and potentially effective in fighting the cancer.
