PDT-lipo: Photo-induction as a Means to Improve Cisplatin Delivery to Pleural Malignancies
Study Details
Study Description
Brief Summary
This clinical study aims to explore intrapleural low-dose Visudyne®-mediated photodynamic therapy (photo-induction) as a pathway to promote the uptake of systemically administered Lipoplatin™ in pleural malignancies of patients undergoing video-assisted talcage for their malignant pleural effusions. Photo-induction is expected to overcome the chemo-resistance of pleural malignancies for cisplatin-based chemotherapeutics and thereby improve local tumor control.

Phase 1 |
Detailed Description
The primary objective of the study is to assess the safety and tolerability of intrapleural Visudyne®-mediated photo-induction as a means to selectively increase tumor uptake of systemically administered Lipoplatin™ in patients with primary or secondary pleural malignancies.
The secondary objectives are:
Assessment of treatment efficacy as measured by dyspnea reduction, pleural effusion free survival as well as local relapse rate, progression free and median overall survival.
Analysis of the pleural intratumor penetration of Lipoplatin™ by repeated biopsies for Lipoplatin concentration measurements before and after Visudyne® treatment as well as vessel modulation related parameters (pericyte coverage, vessels morphology).
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Lipoplatin/Visudyne-mediated photodynamic therapy 200 mg/m2 Lipoplatin™ will be delivered as iv perfusion. Then, intrapleural photo-induction will be realized through a classical video-assisted thoracoscopic (VATS) approach using 3 mg/m2 Visudyne® activated at 689 nm. At the end of the procedure, the patients will receive chemical pleurodesis by VATS as per standard-of-care treatment for malignant pleural effusion. |
Drug: Cisplatin, liposomal
Lipoplatin IV 200 mg/m2
Other Names:
Drug: Verteporfin
Visudyne® IV 3 mg/m2
Other Names:
Device: Device for Intrapleural Visudyne-mediated Low-Dose Photodynamic Therapy with integrated in situ light dosimetry
Intrapleural photo-induction will be realized in the chest cavity with low-dose PDT using Visudyne® 3mg/m2 as photosensitizer, activated by 689 nm laser light with a fluence of 10J/cm2 and a fluence rate of <10mWcm2.
