Genetically Modified T Cells in Treating Patients With Stage III-IV Non-small Cell Lung Cancer or Mesothelioma

Purpose: This phase I/II trial studies the side effects and best dose of genetically modified T cells in treating patients with stage III-IV non-small cell lung cancer (NSCLC) or mesothelioma. Many types of cancer cells, including NSCLC and mesothelioma, but not most normal cells, have a protein called Wilms tumor (WT)1 on their surfaces. This study takes a type of immune cell from patients, called T cells, and modifies their genes in the laboratory so that they are programmed to find cells with WT1 and kill them. The T cells are then given back to the patient. Cyclophosphamide and aldesleukin may also stimulate the immune system to attack cancer cells. Giving cyclophosphamide and aldesleukin with laboratory-treated T cells may help the body build an immune response to kill tumor cells.

Study of the EZH2 Inhibitor Tazemetostat in Malignant Mesothelioma

Purpose: This is a Phase 2, multicenter, open-label, 2-part, single-arm, 2-stage study of tazemetostat 800 mg two times a day (BID) administered orally. Screening of subjects to determine eligibility for the study will be performed within 21 days of the first planned dose of tazemetostat.

In Part 1, 12 subjects with relapsed or refractory malignant mesothelioma regardless of BAP1 status will be treated and undergo pharmacokinetics (PK) blood sample collection after a single tazemetostat 800 mg.

Part 2 will include subjects with BAP1-deficient relapsed or refractory malignant mesothelioma.

Treatment with tazemetostat will continue until disease progression, unacceptable toxicity or withdrawal of consent, or termination of the study. Response assessment will be evaluated after 6 weeks of treatment and then every 12 weeks thereafter while on study.

A Pilot Window-Of-Opportunity Study of the Anti-PD-1 Antibody Pembrolizumab in Patients With Resectable Malignant Pleural Mesothelioma

Purpose: This is a single institution, single-arm, window of opportunity pilot trial of pembrolizumab in patients with resectable malignant pleural mesothelioma. All patients will undergo a pretreatment PET/CT scan for clinical staging and a VATS procedure to acquire pretreatment tissue. Three cycles of pembrolizumab will then be administered (200 mg IV every 21 days). A PET/CT scan will then be repeated to assess response to pembrolizumab and then surgical resection will be performed via an extended/pleurectomy decortication at least 4 weeks after the third dose of pembrolizumab. Standard adjuvant chemotherapy consisting of cisplatin and pemetrexed for 4 cycles (every 21 days) will be given starting about 6-8 weeks following surgery, after a new baseline CT scan is obtained. Restaging CT scans will be obtained to assess response after every two cycles of chemotherapy. After the completion of standard chemotherapy, optional adjuvant treatment with pembrolizumab will be given to eligible patients for 1 year post-surgery.

Intrapleural Photodynamic Therapy in a Multimodal Treatment for Patients With Malignant Pleural Mesothelioma (MesoPDT)

Purpose: Malignant pleural mesothelioma (MPM) is an aggressive tumour with poor prognosis (median survival <13 months), and high resistance to chemotherapy. Extended pleurectomy/decortication (eP/D) is a debulking surgery of MPM but cannot be considered as a curative treatment. Therefore it has been suggested that eP/D may be of interest if combined with intra-operative treatment and adjuvant therapies.

Photodynamic Therapy (PDT) is an innovative treatment based on the rationale that tumour cells, if previously treated with photosensitizing drugs (Photofrin), will die when exposed to light at a particular wavelength. Interestingly PDT might also stimulate anti-tumour immune response through the release of tumour antigens and induced inflammation.

PDT was tested in phase I-II trials for MPM in combination with EPP or eP/D, and chemotherapy. US studies from J Friedberg et al found very promising survival results in MPM when combining eP/D, but not EPP, intra-operative PDT and chemotherapy (cisplatin-pemetrexed), with a median overall survival of 31.7 months.

However, the definitive value of intra-pleural PDT combined to eP/D in the treatment of MPM still need to be validated. The same multimodal treatment has been established in Lille, the French national expert centre for MPM, with the help of our american colleagues. Therefore, this phase II trial proposes to patients to benefit from the combination of eP/D, intra-operative PDT then chemotherapy by cisplatin-pemetrexed and prophylactic radiotherapy.

Primary endpoint is the feasibility for the patients to have the full multimodal treatment of MPM including intrapleural PDT without unacceptable or unexpected grade III-IV toxicities. Secondary endpoints are PFS, OS, ORR, and quality of life. If the feasibility of such treatment would be confirmed in France, a multicentric, randomized trial comparing this experimental treatment vs control arm (same multimodal treatment without PDT) is planned.

Pembrolizumab in Treating Patients With Malignant Mesothelioma

Purpose:This phase II trial studies how well pembrolizumab works in treating patients with malignant mesothelioma, a cancer of the linings around the lungs (pleura) or abdomen (peritoneum). Monoclonal antibodies, such as pembrolizumab, work by blocking a protein called programmed cell death 1 (PD-1) which may stimulate an immune response and kill tumor cells.

Dendritic Cells Loaded With Allogeneous Cell Lysate in Mesothelioma Patients (MesoCancerVa)

Purpose:Malignant mesothelioma is an aggressive pleural disease, related to asbestos exposure. At present, cytotoxic chemotherapy is the only evidence based treatment for the disease, but efficacy is limited. The investigators have shown both in a murine model, as for the first time in patients, that dendritic cell-based immunotherapy induces tumor specific T-cell responses. However the quality and quantity of the autologous tumor cell lysate to load the dendritic cells was a major impediment for these trials. The investigators have now developed a clinical grade allogeneic tumor cell lysate which can be used to load dendritic cells of patients.

Safety and Efficacy of Oshadi D and Oshadi R for Malignant Mesothelioma Treatment

Purpose:Malignant mesothelioma is a rare neoplasm that arises most commonly from the mesothelial surfaces of the pleural cavity, occasionally from the peritoneal surface, and rarely from the tunica vaginalis or pericardium. It has an extremely poor prognosis with a median survival of 4 to 13 months for untreated patients 1 and 6 to 18 months for treated patients, regardless of the therapeutic approach.

The anticancer activity of Oshadi D and Oshadi R treatment was tested in preclinical studies and in phase I clinical study. Four metastatic mesothelioma patients are treated for 5 to 12 months. The Oshadi D and Oshadi R combination treatment was generally well-tolerated with no dose-limiting toxicities observed.

Reduced Immunogenicity Mesothelin-Targeted Immunotoxin LMB-100 in People With Malignant Mesothelioma

Purpose:LMB-100 is a man-made protein. It is attracted to the mesothelin protein. This is found in many tumors, including mesothelioma. But it is found in only a very small number of normal tissues. After binding to mesothelin on tumors, LMB-100 attacks and kills cancer cells. Researchers want to test LMB-100 in people with advanced mesothelioma. The objective is o find a safe dose and anti-tumor activity of LMB-100 for people with advanced mesothelioma.

Intrapleural Measles Virus Therapy in Patients With Malignant Pleural Mesothelioma

Purpose: This phase I clinical trial investigates the side effects and the best dose of local (intrapleural measles virus therapy in treating patients with malignant pleural mesothelioma (MPM). The investigators anticipate that the intrapleural of the vaccine strain measles virus will enable the virus to specifically infect and kill cancer cells and spare, without damaging normal cells. Furthermore, the investigators expect the measles virus to trigger an anti-tumor immune response which will result in additional destruction of the tumor by immune cells
