Relapse is defined in Outcome Measure 6. KM estimates was used for analyses. |
| Secondary | Phase 2: Percentage of Participants Experiencing Treatment Emergent Adverse Events (TEAEs) | Up to 5 years | An AE was any untoward medical occurrence in a participant after brexucabtagene autoleucel infusion, which did not necessarily have a causal relationship with the treatment. An AE could therefore be any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. TEAEs included all AEs with onset on or after initiation of the brexucabtagene autoleucel infusion. |
| Secondary | Phase 2: Number of Participants Experiencing Laboratory Toxicity Grade 3 or Higher TEAEs Resulting From Increased Parameter Value | Up to 5 years | Grading categories are determined by Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.

| Secondary | Phase 2: Number of Participants Experiencing Laboratory Toxicity Grade 3 or Higher TEAEs Resulting From Decreased Parameter Value | Up to 5 years | Grading categories are determined by CTCAE version 4.03. Grade 1: mild, Grade 2: moderate, Grade 3: severe or medically significant, Grade 4: life-threatening. |
| Secondary | Phase 2: Percentage of Participants With Anti-KTE-X19 Antibodies | First infusion date of brexucabtagene autoleucel (Phase 2) up to 2.7 years | |
| Secondary | Phase 2: Number of Participants With 5-Level European Quality of Life-5 Dimensions (EQ-5D-5L): Health Utility Index Scale | Baseline, Day 28, Month 3, Month 6, Month 9, Month 12, Month 15, Month 18, and Month 24 | The EQ-5D-5 levels(EQ-5D-5L)is a standardized measure of health status of the participant that provides a simple, generic measure of health for clinical and economic appraisal.It is a self-reported questionnaire used to assess the overall health status of participant scoring 5 dimensions of health: mobility,self-care,usual activities,pain/discomfort and anxiety/depression.Each dimension has 5 levels:no problems,slight problems,moderate problems,severe problems,and extreme problems.EQ-5D health states, defined by the EQ-5D descriptive system, are converted into a single summary index by a formula that attaches values (called QOL utilities)to each of the levels in each dimension.EQ-5D Summary Index values range from -0.11(worst health) to 1.00(perfect health).This decision results in a 1-digit number that shows the level for that dimension. The digits for 5 dimensions can be combined to 5-digit number that show the participant's health.Higher scores of EQ-5D-5L indicate better health. |
| Secondary | Phase 2: EQ-5D Visual Analogue Scale (VAS) Score | Baseline, Day 28, Month 3, Month 6, Month 9, Month 12, Month 15, Month 18, and Month 24 | EQ-5D is a self-reported questionnaire used for assessing the overall health status of a participant. The EQ-5D is a participant rated questionnaire to assess health-related quality of life in terms of a single index value. The EQ-5D-VAS records the participant's self-rated health on a 20-cm vertical visual analogue scale and is asked to make a global assessment of their current state of health with 0 indicating the worst health they can imagine and 100 indicating the best health they can imagine. Higher scores indicated a better health state. |
