Arm Description

Each subject will be treated with LCAR-AMDR Cells

Outcomes

Primary Outcome Measures

Incidence, severity, and type of treatment-emergent adverse events (TEAEs)
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
Recommended Phase 2 dose (RP2D) finding
RP2D established through ATD+BOIN design
CAR positive T cells and CAR transgene levels in peripheral blood and bone marrow
CAR positive T cells and CAR transgene levels in peripheral blood and bone marrow after LCAR-AMDR infusion

Secondary Outcome Measures

Overall response rate (ORR)
Objective Response Rate (ORR) is defined as the proportion of subjects who achieve CR or CRi after treatment via LCAR-AMDR cell infusion
Time to Response (TTR)
Time to Response (TTR) is defined as the time from the date of first infusion of LCAR-AMDR to the date of the first response evaluation of the subject who has met all criteria for CR or CRi.
Duration of Response (DoR)
Duration of Remission (DoR) is defined as the time from the first documentation of remission (CR or CRi) to the first documented relapse evidence of the responders
Event-free survival (EFS)
Event-free survival (EFS) is defined as the time from the date of first infusion of the LCAR-AMDR to the first documented treatment failure, disease relapse or death (due to any cause), whichever occurs first
Overall Survival (OS)
Overall Survival (OS) is defined as the time from the date of first infusion of LCAR-AMDR to death of the subject
The proportion of subjects who achieve CR or Cri and obtain bone marrow MRD negative.
The proportion of subjects who achieve CR or Cri and obtain bone marrow MRD negative.
Incidence of anti-LCAR-AMDR antibody and positive sample titer
Venous blood samples will be collected to measure LCAR-AMDR positive cell concentrations and the transgenic level of LCAR-AMDR, at the time points when anti-LCAR-AMDR antibody serum samples are evaluated
