Targeted Anti-CEA CAR-T Immunotherapy for Advanced Lung Cancer
Trial Parameters
Brief 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.
Eligibility Criteria
Inclusion Criteria: \- Participants must meet all of the following criteria to be eligible for enrollment: 1. Age ≥18 years, regardless of gender. 2. Histologically or cytologically confirmed advanced, metastatic, or recurrent lung cancer, including both non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). 3. Disease progression or intolerance after receiving standard therapies (including but not limited to surgery, chemotherapy, radiotherapy, targeted therapy, immunotherapy): NSCLC: Disease progression or intolerance after at least second-line standard therapy. SCLC: Disease progression or intolerance after at least first-line standard therapy. 4. For patients with pleural effusion assigned to the intrapleural infusion group, the pleural effusion volume and characteristics must be accurately assessed by imaging (chest CT or X-ray) combined with cytology. Malignant pleural effusion must be confirmed by the presence of tumor cells in pleural fluid cytology. 5. Tumor CEA
