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 h...

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 ph...
Eligibility Criteria
Inclusion
- Age ≥18 years, regardless of gender.
- Histologically or cytologically confirmed diagnosis of advanced, metastatic, or recurrent lung cancer, including both non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).
- Disease progression or intolerance following at least one line of prior therapy (including but not limited to surgery, chemotherapy, radiotherapy, targeted therapy, or immunotherapy).
- For patients with pleural effusion enrolled in the intrapleural infusion group, accurate assessment of pleural effusion volume and characteristics must be conducted via imaging (chest CT or X-ray) combined with cytological analysis. Cytological examination must confirm the presence of tumor cells in the pleural effusion, indicating malignant pleural effusion.
- Positive tumor CEA expression confirmed by immunohistochemistry (IHC) within 3 months prior to screening (defined as clear membranous staining with a positivity rate ≥10%). If IHC testing of tumor samples was performed more than 3 months prior to screening, the patient's serum CEA must be \>10 ng/mL.
- At least one measurable lesion according to RECIST 1.1 criteria: for non-nodal lesions, the longest diameter must be ≥10 mm; for nodal lesions, the short axis must be ≥15 mm.
- ECOG performance status score of 0-2.
- Expected survival of more than 12 weeks.
- No severe psychiatric disorders.
- Unless otherwise specified, key organ functions must meet the following requirements:
- Hematologic: WBC \>2.0×10⁹/L, neutrophils \>1.0×10⁹/L, lymphocytes \>0.5×10⁹/L, platelets \>50×10⁹/L, hemoglobin \>80 g/L;
- Cardiac function: Left ventricular ejection fraction (LVEF) ≥50% by echocardiography, and no significant abnormalities on ECG;
- Renal function: Serum creatinine ≤2.0×ULN;
- Hepatic function: ALT and AST ≤3.0×ULN (≤5.0×ULN if liver metastases are present);
- Total bilirubin ≤2.0×ULN;
- Oxygen saturation (SpO₂) \>92% on room air.
- Eligible for leukapheresis or peripheral venous blood collection and without contraindications for cell collection.
- Subjects must agree to use reliable and effective contraception (excluding rhythm method) from the time of informed consent until 1 year after CAR-T cell infusion.
- Subject or legally authorized representative must voluntarily sign the informed consent form (ICF), indicating understanding of the study objectives and procedures and willingness to participate in the clinical trial.
Exclusion
- Presence of symptomatic central nervous system (CNS) metastases or leptomeningeal metastases at screening, or other evidence indicating that CNS or leptomeningeal lesions are not adequately controlled, making the patient unsuitable for enrollment as judged by the investigator.
- Participation in another clinical study within 1 month prior to screening.
- Receipt of a live attenuated vaccine within 4 weeks prior to screening.
- Prior antitumor therapies before screening including: chemotherapy, targeted therapy, or other investigational drugs administered within 14 days or at least 5 half-lives (whichever is shorter) before screening.
- Active or uncontrolled infections requiring systemic treatment.
- Tumor compressing the trachea or major blood vessels with high risk as assessed by the investigator.
- Presence of any of the following cardiac conditions:
- New York Heart Association (NYHA) Class III or IV congestive heart failure;
- Myocardial infarction or coronary artery bypass graft (CABG) within 6 months prior to enrollment;
- Clinically significant ventricular arrhythmias or a history of unexplained syncope (excluding vasovagal or dehydration-related causes);
- History of severe non-ischemic cardiomyopathy.
- Active autoimmune diseases or other conditions requiring long-term immunosuppressive therapy.
- History of other untreated or concurrent malignancies within the past 3 years, except for adequately treated cervical carcinoma in situ or basal cell carcinoma of the skin.
- Positive hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) with detectable hepatitis B virus (HBV) DNA levels exceeding the normal range in peripheral blood; positive hepatitis C virus (HCV) antibody with detectable HCV RNA levels exceeding the normal range in peripheral blood; positive for human immunodeficiency virus (HIV) antibodies; or positive syphilis test.
- Pregnant or breastfeeding women.
- Any other condition that, in the opinion of the investigator, renders the patient unsuitable for participation in the study.
