Study Endpoints
Primary Endpoints
Dose-limiting toxicity (DLT) rate
Minimum 2 years after LUCAR-20SP infusion (Day 1)

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.

Incidence, severity, and type of treatment-emergent adverse events (TEAEs)
Minimum 2 years after LUCAR-20SP infusion (Day 1)

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) regimen finding
Minimum 2 years after LUCAR-20SP infusion (Day 1)

RP2D established through accelerated titration design (ATD) and Bayesian Optimal Interval (BOIN) design.

Pharmacokinetics in peripheral blood
Minimum 2 years after LUCAR-20SP infusion (Day 1)

CAR transgene levels in peripheral blood after LUCAR-20SP infusion. CAR positive T cells levels in bone marrow after LUCAR-20SP infusion.

Pharmacokinetics in bone marrow
Minimum 2 years after LUCAR-20SP infusion (Day 1)

CAR positive T cells levels in bone marrow after LUCAR-20SP infusion. CAR transgene levels in bone marrow after LUCAR-20SP infusion.

Secondary Endpoints
Objective Response Rate (ORR) after administration
Minimum 2 years after LUCAR-20SP infusion (Day 1)
Time to Response (TTR) after administration
Minimum 2 years after LUCAR-20SP infusion (Day 1)
Duration of Remission (DoR) after administration
Minimum 2 years after LUCAR-20SP infusion (Day 1)
