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
Incidence, severity, and type of treatment-emergent adverse events (TEAEs)
Time Frame: Minimum 2 years after LUCAR-B68 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

Dose-limiting toxicity (DLT) rate
Time Frame: Minimum 2 years after LUCAR-B68 infusion (Day 1)
