A Study to Evaluate the Safety and Efficacy of Mesothelin-Targeting Logic-gated CAR T, in Participants With Solid Tumors That Express MSLN and Have Lost HLA-A*02 Expression

The goal of this study is to test autologous logic-gated Tmod™ CAR T-cell products in subjects with solid tumors including colorectal cancer (CRC), pancreatic cancer (PANC), non-small cell lung cancer (NSCLC), ovarian cancer (OVCA), mesothelioma (MESO), and other solid tumors that express mesothelin (MSLN) and have lost HLA-A\*02 expression. The main questions this study aims to answer are: Phase 1: What is the recommended dose that is safe for patients Phase 2: Does the recommended dose kill solid tumor cells and protect the patient's healthy cells Participants will be required to perform study procedures and assessments, and will also receive the following study treatments: Enrollment and Apheresis in BASECAMP-1 (NCT04981119) Preconditioning Lymphodepletion (PCLD) Regimen Tmod CAR T cells at the assigned dose
