About this trial
This is a phase I clinical study to evaluate the safety and tolerability of FAST targeted chimeric antigen receptor (CAR)-T cells (PTC13) in patients with carcinoembryonic antigen (CEA)-positive advanced malignant solid tumors, and to obtain the maximum tolerated dose of FAST CAR-T (PTC13) and phase II Recommended dose.
Eligibility criteria
Qualifiers
Age≥18 years, regardless of gender.
Diagnosed with advanced, metastatic, or recurrent malignant tumors confirmed by histology or pathology, primarily including colorectal cancer, esophageal cancer, gastric cancer, pancreatic cancer, lung cancer, or cholangiocarcinoma.
Failure of at least second-line standard therapy (due to disease progression or intolerance, such as surgery, chemotherapy, radiotherapy, etc.) or a lack of effective treatment options.
Immunohistochemical staining of tumor samples within 3 months confirming CEA positivity (distinct membrane staining with a positivity rate of≥10%); if the immunohistochemical result of the tumor sample is more than 3 months old at the time of screening (distinct membrane staining with a positivity rate of≥10%), the patient's serum CEA must exceed 10µg/L.
Disqualifiers
Clinically symptomatic central nervous system or leptomeningeal metastasis at the time of screening, or other evidence suggesting that central nervous system or leptomeningeal metastases are not controlled, as judged unsuitable for inclusion by the investigator.
Participation in another clinical study within 1 month prior to screening.
Receipt of live attenuated vaccines within 4 weeks prior to screening.
Receipt of the following anti-tumor treatments before screening: Chemotherapy, targeted therapy, or other experimental drug treatments within 14 days or at least 5 half-lives (whichever is shorter).
