About this trial
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.
Eligibility criteria
Qualifiers
Age ≥ 18 years, no gender restriction;
Histopathologically confirmed diagnosis of advanced, metastatic, or recurrent malignant tumors, primarily including colorectal cancer, esophageal cancer, gastric cancer, pancreatic cancer, lung cancer, and cholangiocarcinoma;
Failure of at least second-line standard treatment (disease progression or intolerance, such as surgery, chemotherapy, radiotherapy, etc.) or lack of effective treatment options;
Immunohistochemical staining of tumor samples showing CEA positivity (clear membrane staining, positivity rate ≥ 10%) within the past 3 months; if the immunohistochemical result is older than 3 months (clear membrane staining, positivity rate ≥ 10%), serum CEA must exceed 10 µg/L;
Disqualifiers
Clinically symptomatic central nervous system metastasis or meningeal metastasis at screening, or other evidence indicating that central nervous system or meningeal metastasis has not been controlled, as determined by the investigator, making the patient unsuitable for enrollment.
Participation in another clinical trial within 1 month prior to screening.
Receipt of live attenuated vaccines within 4 weeks prior to screening.
Received the following anti-tumor treatments within 14 days or at least 5 half-lives (whichever is shorter) prior to screening: chemotherapy, targeted therapy, or other experimental drug treatments.
