Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of this study is to test the safety of a combination of the study drug called WST11 and PDT. Photodynamic therapy (PDT) is a type of ablation therapy (treatment which destroys tumor cells) which has been previously approved for the treatment of patients with other cancers. It works by using a drug that is given through the vein and then is activated in the tumor by light administered during endoscopy, which results in destruction of the cancer cells.
