Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: LCAR-M23 Chimeric Antigen Receptor T cell
Biological: LCAR-M23 cells
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). A single dose, single Infusion of LCAR-M23 is scheduled 5 to 7 days after the initiation of the premedication regimen.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Chimeric Antigen Receptor T (CAR-T) Positive Cell Concentration
Time Frame: 2 years post infusion
Venous blood samples will be collected for measurement of CAR-T positive cellular concentration
2 years post infusion
Dose-limiting toxicity (DLT) and incidence, severity, and type of treatment-emergent adverse events (TEAEs)
Time Frame: 90 days post infusion
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.
90 days post infusion
MTD/ RP2D regimen finding
Time Frame: 90 days post infusion
Maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D)
90 days post infusion

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Disease control rate (DCR) after administration
Time Frame: 2 years post infusion
Disease Control Rate (DCR) is defined as the proportion of patients with complete response, partial response and stable disease.
2 years post infusion
Objective Response Rate (ORR) after administration
Time Frame: 2 years post infusion
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.
2 years post infusion
Time to Response (TTR) after administration
Time Frame: 2 years post infusion
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.
2 years post infusion
Duration of Response (DOR) after administration
Time Frame: 2 years post infusion
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).
2 years post infusion
Progress Free Survival (PFS) after administration
Time Frame: 2 years post infusion
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.
2 years post infusion
Overall Survival (OS) after administration
