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
Rate and severity of adverse events (AEs) and severe adverse events (SAEs)
Time Frame: 2 years
An AE is defined as any unfavorable and unintended sign, symptom, or disease (new or worsening) temporally associated with the use of study therapy, regardless of whether or not a causal relationship with the study therapy can be determined.
2 years
Rate and severity of clinically-significant abnormalities in laboratory testings
Time Frame: 2 years
Clinically-significant abnormalities in laboratory testings.
2 years
Rate of dose-limiting toxicities (DLTs)
Time Frame: 28 days
Dose-limiting toxicity (DLT) is defined as an adverse event that occurred within 28 days after JWTCR001 infusion that met any of the following criteria. Any Grade ≥3 non-hematologic toxicity associated with JWTCR001 that has not resolved to Grade ≤2 within 7 days, excluding clinically insignificant abnormalities in laboratory indicators. Grade ≥3 hematological toxicities. Grade ≥3 anaphylaxis. Grade ≥3 infection did not resolve to Grade ≤2 within 7 days after anti-infective treatment. Grade ≥3 autoimmune toxicity during treatment. Grade ≥3 cytokine release syndrome (CRS) during treatment that did not resolve to Grade ≤2 within 72 hours.
