This phase I trial studies the side effects and best dose of vascular-targeted photodynamic therapy with padeliporfin in treating dysphagia in patients with stage IV esophageal cancer. Padeliporfin is a photosensitizing drug which stays in the blood vessels and becomes active when exposed to light. Vascular-targeted photodynamic therapy uses a laser to activate padeliporfin and may kill tumor cells and improve swallowing in patients with esophageal cancer.
Study sponsor and potential other locations can be found on ClinicalTrials.gov for NCT03133650.
PRIMARY OBJECTIVE:
I. To determine the maximally tolerated laser light fluence rate (mW/cm) of light exposure for vascular-targeted photodynamic (VTP) treatment of malignant obstruction due to esophagogastric cancer (EGC), using a fixed dose of padeliporfin (WST11).
SECONDARY OBJECTIVES:
I. To assess the toxicities of VTP.
II. To assess the efficacy of VTP in relieving dysphagia.
III. To evaluate the histologic tissue response to VTP in the esophagus.
IV. To evaluate the immune response to VTP and effects on local and distant disease.
OUTLINE: This is a dose-escalation study of vascular-targeted photodynamic therapy.
Patients receive padeliporfin intravenously (IV) over 10 minutes and then undergo vascular-targeted photodynamic therapy over 20 minutes during upper endoscopy on day 0.
After completion of study treatment, patients are followed up for 60 days.
