Experimental: Vascular-targeted photodynamic therapy (VTP) using WST11
Participants will receive intravenous administration of WST11 at a dose of 4 mg/kg, infused over 10 minutes, during an endoscopy procedure, followed by immediate laser light application.
Drug: WST 11-mediated VTP therapy
Administration of WST11 in conjunction with endoscopic illumination at 753 nm emitted by a diode laser and administered to the participant by optical fibre catheters (cylindrical light diffusers) and a standard upper GI endoscope.
- Maximum tolerated laser fluence rate [ Time Frame: 60 days ]The maximally tolerated laser light fluence rate (mW/cm) of light exposure for VTP of malignant obstruction due to esophagogastric cancer will be measured by examining 6 fluence rates beginning with a fluence rate of 150 nW/cm, then increasing by 50mW/cm, up to a maximum of 400 mW/cm (150, 200, 250 300, 350, 400).
