Anti-Mesothelin TNaive/SCM hYP218 (TNhYP218) CAR T Cells in Participants With Mesothelin-Expressing Solid Tumors Including Mesothelioma
Trial Parameters
Brief Summary
Background: Mesothelioma is an aggressive cancer that grows in the linings of the body; this can include the membranes that line the heart, lungs, and internal organs. Mesothelin (MSLN) is a protein that appears in high numbers in many tumors, including mesothelioma. Researchers are developing a new treatment that collects a person s own immune cells (T cells); the T cells are genetically modified to target and kill tumor cells with high levels of MSLN. Objective: To test a new treatment (TNhYP218 CAR T cells) in people with solid tumors including mesothelioma. Eligibility: People aged 18 and older with solid tumors including mesothelioma that returned or spread after standard treatment. Design: Participants will be screened. A small piece of tissue will be cut from a tumor (biopsy). The sample will be tested to see if it has enough MSLN. Participants will undergo leukapheresis: Blood will be taken from their body through a vein. The blood will pass through a machine that separates out the T cells. The remaining blood will be returned to the body through a different vein. Participant s T cells will be modified in a lab to produce TNhYP218 CAR T cells. Participants will enter the hospital. For 7 days, they will receive drugs to prepare their bodies for the study treatment. TNhYP218 CAR T cells will be administered into a vein. Participants will remain in the hospital for at least 7 more days. After discharge, participants will have follow-up visits for 5 years. These visits may include imaging scans, blood and heart tests, and a new biopsy. Long-term follow-up will continue another 10 years.
Eligibility Criteria
* INCLUSION CRITERIA: In order to be eligible to participate in this study, an individual must meet all of the following criteria. For this protocol, treatment initiation is defined as the first day of lymphodepleting chemotherapy. * Participant must have unresectable, locally advanced, or metastatic, or recurrent mesothelioma and other mesothelin expressing solid tumors. For participants with mesothelioma only those with epithelioid or biphasic histology (with \>80% epithelioid component) will be eligible. The diagnosis will be confirmed by the Laboratory of Pathology, CCR, NCI. * Participant must have progressed on at least one FDA-approved systemic therapy considered standard of care for their tumor type. There is no limit on the number of prior treatment regimens. Note: Given the aggressive nature of pancreatic cancer, otherwise eligible individuals with this cancer type can undergo leukapheresis before or while they are getting their frontline treatment as long as they meet all ot
