Epithelial Tumors, Malignant clinical trials

Phase I Evaluation of Immunotoxin LMB-100 Administered by Normothermic, Intrapleural Perfusion Following Cytoreductive Surgery in Participants With Pleural Mesotheliomas, or Pleural Effusions From Cancers Expressing Mesothelin

Background: Cancers that spread into the thin tissue lining your lungs (pleura) cause serious illness. They often recur when removed. These tumors include malignant pleural mesothelioma (MPM), caused by exposure to asbestos and related fibers. Malignant pleural effusions (MPEs) are caused when cancers in other parts of the body spread to the lungs and pleura. Many people diagnosed with pleural tumors survive less than a year. Objective: To test the safety of a study drug (LMB-100) in people. LMB-100 may help stop pleural tumors from recurring after surgery. Eligibility: People aged 18 years or older diagnosed with MPM or related cancer that has spread into the pleura. Design: Participants will undergo screening. They will have a physical exam with blood and urine tests. They will have CT scans. They will have tests that measure the how their heart and lungs function. They will provide a sample of tumor tissue to determine if their tumor expresses a protein called mesothelin. Participants will undergo standard surgery to maximally remove the plural tumors. Then they will have LMB-100 pumped into their chest. The liquid will rinse the chest wall, diaphragm, heart sac, and surface of the lungs for 90 minutes. Then the liquid will be drained and the surgical incisions closed. The participants will be under anesthesia during this procedure. Participants will remain in the intensive care unit for a least 48 hours. They will remain in the hospital for up to a week or more until recovered enough to be safely discharged. Participants will return for regular follow-up visits for 2 years.
