Study Details
Study Description
Brief Summary
Phase 1/1b, safety, feasibility, and light dose titration study followed by further study of therapeutic ablation effects.
Patients with high risk of peripheral primary lung cancer, stage 1A1/1A2, for whom surgical treatment is planned, will be recruited. Surgery will be performed at 5-21 days following the VTP procedure.

Phase 1 |
Detailed Description
A multicenter, open label, phase 1/1b, safety, feasibility, and light dose titration study followed by further study of therapeutic ablation effects.
Patients with high risk of peripheral primary lung cancer, stage 1A1/1A2, for whom surgical treatment is planned, will be recruited. Patients who are candidates for lung resection will be recruited as a diagnose and treat in the same anaesthesia, protocol; surgery will be performed at least 5 days and up to 21 days following the VTP procedure.
Study intervention will consist of robotic assisted bronchoscopic Padeliporfin VTP lung ablation: vascular targeted photodynamic therapy using Padeliporfin photosensitizer, an ablation mechanism with efficacy related to immune response post-ablation.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Part A will be a monotherapy light dose escalation with single dose of Padeliporfin at light laser doses of 150, 250 and 400 mW/cm for 20 minutes. Part A will proceed with light dose escalation and will continue until the maximum tolerated light dose (MTD) and/or recommended phase 2 dose (RP2D) is defined. |
Combination Product: Padeliporfin Vascular Targeted Photodynamic (VTP) therapy
Bronchoscopy will be performed with robotic assisted approach using standard practices using general anaesthesia and placement of the optic fiber intratumorally followed by IV administration of Padeliporfin for 10 min and laser light illumination.

| Experimental: Part B will be a dose expansion part at MTD/RP2D dose level identified in Part A to further assess the safety, tolerability, and treatment effect of the MTD and/ or RP2D |
Combination Product: Padeliporfin Vascular Targeted Photodynamic (VTP) therapy
