Study Summary

This trial is testing a new cancer treatment to see what the highest safe dose is.

Who is the study for?
This trial is for adults with esophageal cancer that's inoperable or has spread to other organs. They should have a performance status indicating they can still carry out daily activities and must not have had recent systemic therapy. Adequate organ function is required, and women of childbearing potential must test negative for pregnancy and use contraception.Check my eligibility
What is being tested?
The study tests the highest safe dose of WST-11 VTP, a new photodynamic therapy using laser light to treat swallowing difficulties caused by esophageal cancer obstruction.See study design
What are the potential side effects?
Potential side effects are not explicitly listed but may include typical reactions to photodynamic therapies such as tissue inflammation, discomfort at the treatment site, photosensitivity reactions, or changes in blood parameters due to organ response.
