Peritoneal 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.
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.
Purpose:Malignant mesothelioma is a malignancy arising from the mesothelial cells of the pleura, peritoneum, pericardium, or tunica vaginalis.Mesothelioma accounts for 0.10% of deaths annually in the United States. Malignant pleural mesothelioma is the most common of these, comprising of 80% of the cases with an annual incidence of about 2,500 in the United States.The median survival from diagnosis of pleural mesothelioma is approximately 12 months. The majority of patients present with stage III or IV disease with 85-90% of patients considered unresectable at diagnosis. Peritoneal mesothelioma has a better prognosis than pleural mesothelioma; nevertheless, patients undergoing therapy for peritoneal mesothelioma have few well-studied treatment options due in large part to the rarity of the disease.
Purpose:Asbestos defines a group of naturally occurring mineral silicate fibers which are easily inhaled, resulting in a variety of diseases of the respiratory system including lung cancer and malignant mesothelioma. Despite some advances in treatment, there has been little impact on overall survival for both lung cancer and mesothelioma in the past 20 years in great part because patients usually present with disease at an advanced and incurable stage. This study aims to develop and implement a low-dose computed tomography (LDCT) screening approach for lung cancer and mesothelioma in asbestos-exposed workers in Alberta.
Purpose: The aim of this study is to identify biomarkers of disease recurrence and prognosis to optimize patient selection for treatment with cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC), and through animal models to explore different treatment strategies for peritoneal surface malignancies (PSM).
Purpose:
This trial is to determine the safest dose of a triple combination (chemokine modulatory regimen or CKM) of celecoxib, interferon alfa (IFN), and rintatolimod that can be given with a DC vaccine as treatment of peritoneal surface malignancies after standard of care surgery.
The first phase of this study will determine the safest dose of IFN that can be given in combination with celecoxib and rintatolimod along with a DC vaccine. The doses of celecoxib (400 mg) and rintatolimod (200 mg) will be consistent while the dose of IFN will be increased (5, 10, or 20 MU/m2) as participants are enrolled to the trial. The high dose of IFN in combination with celecoxib and rintatolimod will be used for the next phase of the clinical trial. After surgery, participants will receive 2 cycles of the investigational treatment.
The second phase of this study will test if the investigational treatment has any effects on peritoneal surface malignancies. The doses of the combination determined in the first phase will be used in this phase of the clinical trial. After surgery, participants will receive 2 cycles of the investigational treatment, followed by standard chemotherapy as determined by their oncologist, and then 2 more cycles of the investigational treatment.
Purpose: The purpose of this study is to assess the safety of combination treatment of GSK2256098 and trametinib in mesothelioma subjects and subjects with other selected tumor types. Also, the study will identify a maximum tolerated combination dose of GSK2256098 and trametinib. This study is a Phase I, open-label, dose-escalation study to determine maximal tolerated dose (MTD) and the recommended Phase 2 dose (RP2D) and regimens for oral MEK inhibitor trametinib (once daily [OD]dosing) and the oral FAK inhibitor GSK2256098 (twice daily [BID] dosing). The synergy of the combination was observed over a wide range of concentrations and results in several-fold reduction in compound concentration to achieve equivalent biological responses compared to either single agent. The dose and schedule of dosing may be modified based on emerging safety, pharmacokinetic (PK), and pharmacodynamic (PD) data. The study will be conducted in two parts; Part 1 Dose Escalation to determine the MTD and RP2D and Part 2 Expansion Cohort to further evaluate the safety and tolerability of trametinib and GSK2256098 at the RP2D and determine clinical activity. Additionally, in Part 1 Dose Escalation, additional subjects with malignant pleural mesothelioma (MPM) will be recruited at doses that are considered tolerable in order to assess PD in MPM subjects at each dose (the Pharmacodynamic Cohort). The Expansion Cohort will be limited to subjects with MPM who have progressed or are intolerant to first-line therapy.
- Arm: Experimental: Part 1
- Part 1 will determine the MTD and RP2D based on the safety and tolerability of GSK2256098 administered with trametinib. Subject will be administered starting dose of 1.0 mg OD trametinib combined with 500 mg BID GSK2256098. Dose escalation will continue until the MTD is established.

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.
