Summary

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.

Conditions

Interventions

BIOLOGICAL

Targeted CEA CAR-T

Subjects meeting the transfusion criteria will receive pre-treatment, which is as follows: fludarabine 25mg/m2/d×3day and cyclophosphamide 300mg/m2/d×3day, and intravenous CEA CAR-T therapy after 1-2 days of rest

BIOLOGICAL

Targeted CEA CAR-T

Subjects meeting the reinfusion criteria will receive pre-treatment with fludarabine 25mg/m2/d×3day and cyclophosphamide 300mg/m2/d×3day, rest for 1-2 days, and intraperitoneal reinfusion targeted CEA CAR-T therapy
