About this study
Official title: Clinical Study of CEA Targeting Chimeric Antigen Receptor T Lymphocytes (CAR-T) for CEA Positive Advanced Lung Cancer
Lung cancer is the leading cause of morbidity and mortality in the world, of which 80%-85% are non-small cell lung cancer (NSCLC). Most patients with NSCLC are at the advanced stage of diagnosis and have a poor prognosis. The 5-year survival rate of stage III patients is about 15%, the 5-year survival rate of stage IV patients is less than 5%, and the median survival time is only 7 months.
CEACAM5 (CEA), also known as CD66e, is a classic tumor marker that has been used as a marker for many types of tumors for 50 years. It is mainly expressed in lung cancer, esophageal cancer, bile duct cancer, colorectal cancer, gastric cancer and other tumor types.
In previous CAR-T-related clinical trials targeting CEA, the research team found that CAR-T cell preparations had a certain killing effect on CEA positive tumor cells. At the same time, CAR-T cell preparations cannot be sustained for a long time in the body, which is also a key factor restricting the anti-tumor effect of CAR-T cells in the body. To solve this problem, the killing ability and survival ability of CAR-T cell preparations on tumor cells in vitro and in vivo were improved by optimizing CAR structure and improving culture mode.
Read the detailed description
This study is a single-arm, open, enhanced 3+3 dose-ascending + dose-extending clinical study, aiming to evaluate the safety and efficacy of CAR T cell preparations, initially observe and study the pharmacokinetic characteristics of drugs in CEA positive advanced lung cancer patients, and obtain the recommended dose of CAR T cell preparations for CEA positive advanced lung cancer patients.
