About this trial
The ENSURE trial is an open label, single center, phase 1, feasibility study. Sixteen adult patients diagnosed with resectable epithelioid malignant pleural mesothelioma (MPM) will be enrolled following first-line chemotherapy. Before standard-of-care chemotherapy, a leukapheresis will be performed and monocytes will be used for differentiation to dendritic cells (DCs) using specific cytokines. Allogeneic tumor lysate (Pheralys) loaded autologous DCs (MesoPher) will be re-injected 3 weeks after completing chemotherapy, 2 times every other week. Four weeks after the first injection with dendritic cell therapy (DCT), patients will undergo extrapleural pleurectomy/decortication (eP/D) surgery and receive three bi-weekly injections with DCT (starting 4 weeks after surgery). In total, five DC vaccinations will be administered. A tumor biopsy will be collected before starting neo-adjuvant DCT.
Eligibility criteria
Qualifiers
Patients with a histologically confirmed diagnosis of epithelioid MPM who are eligible for 2 to 4 cycles of platinum-based chemotherapy. Patients who progressed after chemotherapy will not be discontinued from the trial if they are still eligible for eP/D and none of the
Disqualifiers
Patients must be at least 18 years old and must be able to give written informed con-sent.
Resectable disease defined by stage cT1-3, N0-1, M0 (I to IIIA) according to UICC TNM classification (8th edition). A fluorodeoxyglucose (FDG)-positron emission tomography (PET)-computerized tomography (CT) scan with fusion images showing absence of M1, N2 involvement is required. Focal chest wall lesions are acceptable.
Tumor tissue available after completing chemotherapy and before starting treatment with DCT. Tumor tissue can be obtained by either a CT-guided needle biopsy or a Video-assisted thoracoscopic surgery (VATS) biopsy.
Fit to receive platinum-based chemotherapy (as per standard of care of the treating physician/Institution) and undergo a P/D with optional removal of hemidiaphragm and pericardium. The responsible surgeon and chest physician should judge the required fitness prior to registration, taking into account the results of all the relevant (i.e. pulmonary, cardiac) examinations.
