Summary

Pilot study of the feasibility of an innovative multimodal treatment combining intrapleural photodynamic therapy with videothoracoscopy followed by adjuvant immunotherapy with anti-PD-1 Nivolumab antibodies in patients with malignant pleural mesothelioma

Conditions

  • Mesotheliomas Pleural
  • Malignant Pleural Mesothelioma

Interventions

DEVICE

intrapleural photodynamic therapy with videothoracoscopy

MPM patients will be first administrated 20 mg/kg of oral photosensitizer, 5-Aminolevulinic Acid (5-ALA) {Gliolan®}, 4 to 6 hours prior undergoing thoracoscopy (VATS). During VATS procedure, after a qualitative control of the fluorescence of tumor lesions and some guided pleural tumor biopsies, the pleural cavity will be illuminated using a flexible probe and laser source at a specific wavelength for 5-ALA (400-500 nm; 25 J/cm2) during 15 minutes (6 fractions of 2.5 minutes separated by 5 pauses of 2 minutes each to improve tissue oxygenation for the PDT reaction). An IPC device (but no talc) will be inserted and used for pleurodesis and may permit to collect further pleural effusion samples. As 5-ALA has a short half-life and thus does not need extensive precautions to avoid patient photosensitivity, the patient would not stay longer than a standard procedure (about 2-3 days in the hospital)

DRUG

Nivolumab Injection

Seven to 10 days after VATS, patients will start to be treated by Nivolumab 240mg IV every 2 weeks till progression (CT-scan reassessment every 8 cycles), unacceptable toxicity, or maximum 2 years.
