Summary

This trial is testing the safety and effectiveness of new drugs, either alone or in combination with pembrolizumab and/or chemotherapy, for people with a specific type of esophageal cancer who have

Who is the study for?

This trial is for individuals with advanced esophageal cancer who have already tried treatments targeting PD-1/PD-L1 proteins. Participants should be ready for second-line therapy and meet other health criteria set by the study.

What is being tested?

The study tests various agents, like Sacituzumab tirumotecan and Lenvatinib, with or without Pembrolizumab (a known immunotherapy drug) and/or chemotherapy to see their effects on esophageal cancer after first treatment has failed.

What are the potential side effects?

Potential side effects may include allergic reactions, inflammation, fatigue, nausea, lowered blood cell counts increasing infection risk, liver function changes, and potential infusion-related reactions.
