This study was a phase I safety and tolerability clinical trial conducted in a single-center, open-label, 3+3 design with dose escalation.
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.
All participators received lymphoid-depleted preconditioning before Super1 TCR-T cells infusion. Super1 TCR-T cells were infused 3 days later. Concomitant administration of interleukin for 7 consecutive days.

Outcomes
Primary Outcomes
DLT
Determining the dose-limiting toxicity (DLT) of Super1 TCR-T adoptive Immunotherapy
Time frame: Up to 28 Days
MDT
Determining the maximum Tolerated dose (MTD) of Super1 TCR-T adoptive Immunotherapy
Time frame: Up to 28 Days
Secondary Outcomes
ORR
Objective response rate,defined as the proportion of subjects with a confirmed PR or better best response
Time frame: One year after cell reinfusion
OS
overall survival，time from subject's treatment to death. Participants with no death recorded at the time of statistical analysis were censored at the time of the last follow-up. In cases of loss to follow-up, data were censored at the date of the last contact with the participant.
Time frame: One year after cell reinfusion
PFS
progression-free survival ，the time from the subject's treatment to the occurrence of PD or death from any cause, whichever occurred first. If no event (PD or death) occurred, the date of the last response assessment was the censored time for PFS.
