Detailed Description
This study consists of two phases: the first phase will be the dose exploration phase (Phase I), followed by the dose extension phase.
In the dose escalation of the study, 3 subjects are enrolled for 1st treatment group, starting with single dose of ScTIL injection of 5x10^9 alone. If there is no dose limiting toxicity (DLT) observed, 3 subjects are enrolled into treatment groups successively in sequential order of: Group 2: ScTIL1.0x10^10; Group 3: ScTIL 2.0x10^10.
After the completion of ScTIL reinfusion for first subject of the 1st dose group, the subject will be observed for no less than 7 days. If no serious toxic and adverse events occurres, ScTIL reinfusion for the second and third subjects will be performed. If no DLT occurres by the 21th days after completion of reinfusion for the 3rd subject, The study will proceed to the next treatment group. If 1/3 of enrolled subjects have DLT, another 3 subjects will be enrolled. In any of the dose groups, if less than 1/6 subjects have DLT, subject enrollment for the next treatment group will start. If DLT occurs in more than 2/6 of subjects, the number of subjects in the previous dose group will be reviewed. If there were only 3 subjects, 3 more subjects will be enrolled. If DLT occurs in less than 1/6 subjects, the dose will be defined as the maximum tolerable dose (MTD), and the dose escalation phase of the study will be completed. If DLT occurs in more than 2/6 subjects in the first dose group, a dose reduction exploration will be performed or the study will be terminated upon decision made by the Safety Committee.
Appropriate doses will be selected by investigator for the dose extention phase study.

EXPERIMENTAL: ScTIL injection
In the dose escalation of the study, starting with the dose of injection of 5x10^9.
If there is no DLT, followed by the second dose of 1.0x10^10 until the third dose of 2.0x10^10.
|
Peripheral blood mononuclear cells (PBMCs) obtained via apheresis are used for cell preparation.
PD-1 positive T cells are isolated from PBMCs, are transduced with lentivirus loaded with "enhanced receptor" and "superamplification factor", and cell number are amplified.
The obtained ScTIL is used for one-time intravenous infusion.
