Innovative treatment combining photodynamic therapy and immunotherapy for malignant pleural mesothelioma

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This pilot study investigates the feasibility of a novel multimodal treatment approach for patients with unresectable malignant pleural mesothelioma. It combines intrapleural photodynamic therapy using videothoracoscopy with adjuvant immunotherapy using Nivolumab, an anti-PD-1 antibody. The study aims to assess the effectiveness of this combination in patients who have previously undergone chemotherapy and are experiencing disease progression. The treatment is designed to target malignant pleural lesions directly while enhancing the immune response against the cancer.

* Women of child-bearing potential must have a negative pregnancy test within 24h before administration of investigational product
* First line patients may also be recruited if they declined or if they have contra-indications for chemotherapy.

Exclusion Criteria:
