Study Endpoints
Primary Endpoints
Incidence, severity, and type of treatment-emergent adverse events (TEAEs)
Baseline to 104 Weeks after last subject infusion

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.

Incidence of dose-limiting toxicity (DLT)
30 days after LCAR-AIO infusion (Day 1)

DLTs are severe adverse events refers to any untoward medical occurred in a subject participated in a clinical investigation, which have a causal relationship with the treatment and will limit the dose escalation.

Chimeric Antigen Receptor T (CAR-T) Positive Cell Concentration
Baseline to 104 Weeks after last subject infusion

Venous blood samples will be collected for measurement of CAR-T positive cellular concentration.

Recommended Phase 2 Dose (RP2D) regimen finding
Baseline to 104 Weeks after last subject infusion

RP2D established through dose exploratory.

Transgene Levels of LCAR-AIO CAR-T Cells
Baseline to 104 Weeks after last subject infusion

Transgene Levels of LCAR-AIO CAR-T Cells using sensitive assay methods will be assessed

Secondary Endpoints
Annua Relapse Rate (ARR)
Baseline to 104 Weeks after last subject infusion
Change in Expanded Disability Status Scale (EDSS) scores from baseline up to 104 weeks
Baseline to 104 Weeks after last subject infusion
Changes in Visual Acuity from baseline up to 104 weeks
