Padeliporfin VTP Treatment for Unresectable Pancreatic Adenocarcinoma

Locally Advanced Unresectable Pancreatic Adenocarcinoma Clinical Trial

Official title: A Multicenter Open-label Phase 1 Trial to Evaluate Safety and Preliminary Efficacy of Endovascularly Applied Vascular Targeted Photodynamic Therapy (VTP) for Patients With Locally Advanced Unresectable Pancreatic Ductal Adenocarcinoma

Status Active, not recruiting

Clinical Trial Summary

This is a prospective, multicenter, non-randomized, open label light dose escalation phase I trial to evaluate the safety and preliminary efficacy of Padeliporfin vascular targeted photodynamic therapy (VTP) applied via endovascular fiber placement within a dilatation catheter, through the superior mesenteric artery (SMA) in patients with stage III, locally advanced (LA) unresectable pancreatic ductal adenocarcinoma (PDAC). The investigators will evaluate safety and preliminary efficacy of Padeliporfin VTP administered endovascularly using light dose escalation.

Clinical Trial Description

This is a prospective, multicenter, non-randomized, open label light dose escalation phase I trial to evaluate the safety and preliminary efficacy of Padeliporfin vascular targeted photodynamic therapy (VTP) applied via endovascular fiber placement within a dilatation catheter, through the superior mesenteric artery (SMA) in patients with stage III, locally advanced (LA) unresectable pancreatic ductal adenocarcinoma (PDAC) with SMA solid tumor encasement >180°. The investigators will evaluate safety and preliminary efficacy of Padeliporfin VTP administered endovascularly using light dose escalation.

Study Intervention: Patients enrolled in the study will undergo endovascular VTP, using Padeliporfin (WST-11) activated via endovascular fiber placement through the SMA, with intravenous administration of Padeliporfin at a fixed dose of 4 mg/kg of padeliporfin di-potassium, followed by total of 10 min illumination at 753 nm.

For light dose escalation (Part A), a 3+3 dose-escalation schema will be used. In a subsequent expansion phase (Part B), the optimal light dose as per light dose escalation, will be used in an additional cohort of patients to further evaluate preliminary efficacy. ;
