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
SS1P and Pentostatin Plus Cyclophosphamide for Mesothelioma
Purpose:Malignant mesothelioma is a form of cancer that develops on the protective lining that covers the body s internal organs. It most often occurs on the lining of the lungs and chest wall or the lining of the abdomen. There is no known cure for malignant mesothelioma, so researchers are searching for new ways to treat it. Mesothelin is a protein that is found in mesothelioma and other types of cancer cells. An experimental cancer drug called SS1P is designed to attack cells that have mesothelin while leaving healthy cells alone. Researchers want to test how effective SS1P is when it is given with pentostatin and cyclophosphamide. These drugs help suppress the immune system and may make the SS1P more effective.
Intrapleural Administration of HSV1716 to Treat Patients With Malignant Pleural Mesothelioma
Purpose:HSV1716, an oncolytic virus, is a mutant herpes simplex virus (HSV) type I, deleted in the RL1 gene which encodes the protein ICP34.5. Malignant mesothelioma is an aggressive, asbestos-related tumour of the pleural and peritoneal cavities. It is a rare cancer which occurs in individuals who have been exposed to asbestos, although it typically occurs decades after exposure (10-40 years later). Malignant pleural mesothelioma forms plaques that are distributed on the surface of the pleural space in the lung. Approximately 30% of patients require an indwelling pleural catheter for drainage of pleural effusions. In this patient group, the indwelling catheter may be used to facilitate loco-regional delivery of HSV1716 to the pleural space. This study seeks to evaluate the safety and biological effects of single and multiple administrations of HSV1716 in the treatment of malignant pleural mesothelioma.
Efficacy and Safety of PIPAC/PITAC in Gastric,Ovarian, Colorectal Cancer and Mesothelioma With Pleural Carcinomatosis. (PIPAC/PITAC)
Purpose:Outcome measurement for patients with gastric, ovarian, colorectal, or pleural cancer/mesothelioma with peritoneal/pleural carcinomatosis undergoing pressurized intraperitoneal/intrathoracal aerosol chemotherapy (PIPAC/PITAC) with cisplatin and doxorubicin or oxaliplatin. Record of (partial/total) tumor response rate via survival rate, time until tumor progression (according to RECIST-criteria), peritoneal carcinomatosis index (PCI) before and after therapy, histological tumor progression/regression, ascites/pleural affusion volume, degree of tumor cell apoptosis.
Do Your Genes Put You at a Higher Risk of Developing Mesothelioma
Purpose: The purpose of this research study is to investigate the possibility that a person’s genes put a person at a higher risk of developing mesothelioma. The investigators will examine genes from DNA (genetic material) isolated from blood. This study will also examine the impact of environmental and work exposures and family history of common cancers on the development of mesothelioma. The genetic markers in this study will basically identify how a person’s body processes frequently encountered environmental pollutants and will not tell about chromosomes, specific diseases, or other potential health problems.
Early Diagnosis of Lung Cancer and Mesothelioma in Prior Asbestos Workers
Purpose: Occupational exposure to asbestos is known increase the risk of developing cancer of the lungs (bronchogenic carcinoma) or of the pleura (mesothelioma). Symptoms are subtle and non-specific, diagnosis is often late and the prognosis consequently is dismal. Currently there is no accepted non-invasive tool for the early diagnosis of mesothelioma or lung cancer in asbestos-exposed subjects. In the last decade, low-dose computed tomography (LDCT) has been successfully developed and validated for the early diagnosis of lung cancer in high-risk smokers. Malignant mesothelioma might, in an early stage, resemble a benign pleural plaque, which is a common finding after asbestos exposure. We target to develop low-dose CT as a tool to serially image the pleural plaques, quantify their individual and overall volume, compute the growth rate with time, and, as such, identify the presence of mesothelioma early, before symptoms occur.
