MT2023-28: A Phase 1 Basket Study Evaluating the Safety and Feasibility of T-Plex, Autologous Customized T Cell Receptor-Engineered T Cells Targeting Multiple Peptide/HLA Antigens in Participants with Antigen-positive Locally Advanced (Unresectable) or Metastatic Solid Tumors


This study aims to find out if investigational new drugs, TSC-204-A0201, TSC-204- A0702 and TSC-200-A0201, can help your cancer better than the standard of care (SOC) that are currently available and accepted by medical experts as a proper treatment. T-cells are part of the immune system and develop from stem cells in the bone marrow. They help protect the body from infection and fight cancer. For this study, T-cells will be collected through a process called leukapheresis. T-cells from your leukapheresis will be used to make the study drugs specifically tailored for you and your immune system. The purpose of the study is to learn if the study drugs are safe and effective in treating your type of cancer.
