Outcome Measures
Primary Outcome Measures
- Dose-Limiting Toxicity（DLT） [28 days]
Safety
- Maximal Tolerable Dose（MTD） [28 days]
tolerability evaluation
- Adverse Event（AE） [28 days]
Incidence rate
- Adverse Event of Special Interest （ AESI） [28 days]
Incidence rate
Secondary Outcome Measures
- Number of cells [52 weeks]
Pharmacokinetics is the "Implantation endpoint" which is defined as the number of copies of the CT0180 DeoxyriboNucleic Acid（DNA）in peripheral blood detected at each visit after infusion until any two consecutive test results are negative or below the detection limit. Duration of CT0180 Cell persistence is the period from the day of infusion to the first negative test result or result lower than the detection limit
- Treatment Emergent Adverse Event(TEAE) [52 weeks]
Incidence rate
- Antitumor efficacy-Objective response rate (ORR) [52 weeks]
The number of cases in which tumor size is reduced to partial response (PR) or complete response (CR) / the total number of evaluable cases (%). In the event of partial response( PR) or complete response (CR), the subjects should confirm it no less than 4 weeks after the first evaluation
- Antitumor efficacy-Duration of response (DOR) [52 weeks]
The period from the first evaluation of complete response ( CR) or partial response (PR) to the first evaluation of progressive disease (PD)or death of any cause.
- Antitumor efficacy-Progression-free survival (PFS) [52 weeks]
The period from the day when the subject receives the first study treatment to the first recorded tumor progression (whether treated or not) or death of any cause, which occurs first
- Antitumor efficacy-Overall survival (OS) [52 weeks]
The period from the first study treatment to any cause of death
- Antitumor efficacy-Disease control rate (DCR) [52 weeks]
The number of cases in which response (PR + CR) and stable disease (SD) are achieved from the start of cell infusion/the total number of evaluable cases (%).
- Antitumor efficacy-Duration of disease control (DDC) [52 weeks]
The period from the first evaluation of CR, PR, or SD to the first evaluation of PD or any cause of death
