About

This study was a phase I safety and tolerability clinical trial conducted in a single-center, open-label, 3+3 design with dose escalation.

Full description

After the subjects signed the informed consent form, the HLA genotype of the subjects was detected. After the HLA genotype was confirmed as A*02, the tumor tissue was detected by immunohistochemistry. The subjects could proceed to the subsequent clinical trial if the NY-ESO-1 immunohistochemistry was positive. Each subject received only one cell reinfusion.

Enrollment: 15 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

    • Total bilirubin (TBIL) ≤1.5×ULN

11. Negative pregnancy tests in women of childbearing potential prior to study treatment; Consent must be given to use effective contraception during treatment.

12. During the whole period of the trial, I can regularly visit the enrolled research institutions for relevant testing, evaluation and management.

Exclusion criteria

1. Patients who received major surgery, conventional chemotherapy, large area radiotherapy, immunotherapy or biological therapy within 4 weeks before entering the trial;
2. Known to produce allergic reactions to any component of the trial treatment;
3. no recovery from previous surgery or treatment-related adverse events to ≤ grade 2 CTCAE;

5. Combined with other serious organic diseases and mental disorders;
6. Have active systemic infection requiring treatment, including active tuberculosis, known HIV positivity, or clinically active hepatitis A, B, or C; (Virus carriers should be excluded)
7. Patients with autoimmune diseases: those with a history of inflammatory bowel disease or a history of autoimmune diseases (such as systemic lupus erythematosus, vasculitis, and invasive lung disease) judged by the investigators to be not suitable for this study should be excluded; (Patients with vitiligo are not excluded).
8. Administration of chronic systemic cortisone steroids, hydroxyurea, and immunomodulatory agents (e.g., interleukin-2, interferon-α or γ, GM-CSF, mTOR inhibitors, cyclosporine, thymosin, etc.) within 4 weeks prior to cell therapy."
