- Rate of dose-limiting toxicities (DLTs) [ Time Frame: 28 days ]Dose-limiting toxicity (DLT) is defined as an adverse event that occurred within 28 days after JWTCR001 infusion that met any of the following criteria. Any Grade ≥3 non-hematologic toxicity associated with JWTCR001 that has not resolved to Grade ≤2 within 7 days, excluding clinically insignificant abnormalities in laboratory indicators. Grade ≥3 hematological toxicities. Grade ≥3 anaphylaxis. Grade ≥3 infection did not resolve to Grade ≤2 within 7 days after anti-infective treatment. Grade ≥3 autoimmune toxicity during treatment. Grade ≥3 cytokine release syndrome (CRS) during treatment that did not resolve to Grade ≤2 within 72 hours. Grade ≥3 TCR-T cell-associated encephalopathy syndrome/immune effector cell-associated neurotoxicity syndrome (CRES/ICANS) that did not resolve to Grade ≤2 within 72 hours. Grade 5 events of any nonmalignant cause.
- Rate and severity of adverse events (AEs) and severe adverse events (SAEs) [ Time Frame: 2 years ]An AE is defined as any unfavorable and unintended sign, symptom, or disease (new or worsening) temporally associated with the use of study therapy, regardless of whether or not a causal relationship with the study therapy can be determined.
- Rate and severity of clinically-significant abnormalities in laboratory testings [ Time Frame: 2 years ]Clinically-significant abnormalities in laboratory testings.
- Copy number of the vector transgene of JWTCR001 in peripheral blood [ Time Frame: 2 years ]The pharmacokinetic parameters of JWTCR001 will be evaluated by quantitative polymerase chain reaction (qPCR) for the copy number of the vector transgene of JWTCR001 in peripheral blood to evaluate T-cell expansion and persistence.
- MAGE-A4 specific TCR+ T Cell concentration of JWTCR001 in peripheral blood [ Time Frame: 2 years ]The pharmacokinetic parameters of JWTCR001 will be evaluated by flow cytometry for the MAGE-A4 specific TCR+ T Cell concentration of JWTCR001 in peripheral blood to evaluate T cell expansion and persistence.
- Antitumor efficacy-Progression-free survival (PFS) [ Time Frame: 2 years ]The period from the day when the subject receives the infusion of cells to the first recorded tumor progression (whether treated or not) or death of any cause, which occurs first.
- Antitumor efficacy-Duration of response (DOR) [ Time Frame: 2 years ]The number of cases in which response are achieved from the start of cell infusion/the total number of evaluable cases (%).
- Antitumor efficacy-Time to response (TTR) [ Time Frame: 2 years ]The time from the first infusion to the first objective tumor response (tumor shrinkage of ≥30%) observed for patients who achieved a CR or PR.
- Antitumor efficacy-Overall survival (OS) [ Time Frame: 2 years ]The period from the first infusion to any cause of death.
- Antitumor efficacy-Objective response rate (ORR) [ Time Frame: 2 years ]The number of cases in which tumor size is reduced to complete response (CR) or partial response (PR) / the total number of evaluable cases (%). In the event of CR or PR, the subjects should confirm it no less than 4 weeks after the first evaluation.
- Antitumor efficacy-Disease control rate (DCR) [ Time Frame: 2 years ]The number of cases in which response are achieved from the start of cell infusion/the total number of evaluable cases (%).
