CEA Targeting Chimeric Antigen Receptor T Lymphocytes (CAR-T) in the Treatment of CEA Positive Advanced Solid Tumors

Recruiting now · Phase 1/Phase 2

Conditions studied: Gastric Cancer, Colon Cancer, Rectal Cancer, Esophageal Cancer, Pancreas Cancer, Lung Cancer, Breast Cancer

In brief

This study is a single-arm, open-label, dose-escalating + dose-expansion clinical study, aiming to evaluate the safety and efficacy of CEA-targeted CAR-T cell preparations, and to preliminarily observe the study drug in CEA-positive advanced malignant tumors. The pharmacokinetic characteristics of CAR-T cell preparations for the treatment of patients with CEA-positive advanced malignancies were obtained and the recommended dose and infusion schedule.
