Gastric Cancer, Metastatic

The investigational product used in this study, UCLH801 cells, is a CAR-T cell therapy specifically targeting CDH17. The proposed indication includes CDH17-positive advanced solid tumors, such as but not limited to colorectal cancer, gastric cancer, pancreatic cancer, biliary tract tumors, neuroendocrine tumors, ovarian cancer, and lung cancer. The primary objective of this study is to evaluate the safety and tolerability of UCLH801 cells in patients with CDH17-positive advanced malignant solid tumors. The secondary objectives include assessing the preliminary efficacy of UCLH801 cells, their pharmacokinetics and pharmacodynamics in the body, and their immunogenicity. This study aims to observe how the infusion of UCLH801 cells affects patients 's body, including any discomfort or changes in laboratory test results. Additionally, it will evaluate whether UCLH801 cells have any effect on tumor. Furthermore, the study will investigate how UCLH801 cells are metabolized; the mechanisms through which they exert their effects, and how to develops any immune response or rejection against UCLH801 cells.

The goal of this clinical research study is to study the recommended dose of TROP2 CAR/IL-15 TGFBR2 KO NK cells that can be given intraperitoneally (infused directly into the stomach area) to participants with adenocarcinoma of the stomach that has spread to the peritoneum. The safety and effectiveness of this treatment will also be studied.

This is a phase I, single arm, open-label clinical study of BioTTT001 in combination with SOX and Toraplizumab in patients with peritoneal metastases from gastric cancer.
