Arm Description

Outcomes

Primary Outcome Measures

Dose-limiting toxicity (DLT) and incidence, severity, and type of treatment-emergent adverse events (TEAEs)
Dose-limiting toxicity (DLT) refers to a drug-related toxicity during treatment with the drug, the severity of which is clinically unacceptable, limiting the further escalation of drug dose. An adverse event refers to any untoward medical occurrence in a clinical investigation subject administered a pharmaceutical product (investigational or non-investigational), which does not necessarily have a causal relationship with the treatment.
MTD/ RP2D regimen finding
Maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D)
Chimeric Antigen Receptor T (CAR-T) Positive Cell Concentration
Venous blood samples will be collected for measurement of CAR-T positive cellular concentration

Secondary Outcome Measures

Disease control rate (DCR) after administration
Disease Control Rate (DCR) is defined as the proportion of patients with complete response, partial response and stable disease.
Objective Response Rate (ORR) after administration
Objective Response Rate (ORR) is defined as the proportion of subjects who achieve CR or PR after treatment via LCAR-M23 cell infusion, and the objective tumor response rate will be calculated for patients with measurable disease as per RECIST 1.1 criteria only.
Time to Response (TTR) after administration
Time to Response (TTR) is defined as the time interval from the date of first infusion of LCAR-M23 cell formulation to the date of the first response evaluation of the subject who has met all criteria for PR or better.
Duration of Response (DOR) after administration
Duration of Response (DOR) is defined as the time from the first documentation of response (PR or better) to the first documentation of disease progression evidence (as per RECIST 1.1 criteria) of the responders (who achieve PR or better response).
Progress Free Survival (PFS) after administration
Progression Free Survival (PFS) is defined as the time interval from the date of first infusion of LCAR-M23 cell formulation to the first documentation of disease progression (as per RECIST 1.1 criteria) or death (due to any cause), whichever occurs first.
Overall Survival (OS) after administration
Overall survival (OS) is defined as the time interval from the date of first infusion of LCAR-M23 cell formulation to death of the subject.

Intervention Name(s)
LCAR-M23 cells
Intervention Description
Prior to infusion of LCAR-M23, subjects will receive a premedication regimen (intravenous infusion of cyclophosphamide 300 mg/m2 and fludarabine 30 mg/m2 once daily for 3 days; fludarabine dose reduction to 25 mg/m2 and cyclophosphamide to 250 mg/m2 are allowed if the subject' s creatinine clearance is 50-70 mL/min/1.73 m2).
