Group Intervention Description Axicabtagene Ciloleucel Axicabtagene Ciloleucel Participants will receive cyclophosphamide 500 mg/m\^2/day intravenously (IV) and fludarabine 30 mg/m\^2/day IV conditioning chemotherapy for 3 days followed by axicabtagene ciloleucel administered as a single IV infusion at a target dose of 2 x 10\^6 anti-cluster of differentiation (CD)19 chimeric antigen receptor (CAR) transduced autologous T cells/kg on Day 0. For participants weighing ≥ 100 kg, a maximum flat dose of axicabtagene ciloleucel at 2 x 10\^8 anti-CD19 CAR T cells will be administered. Participants who achieve partial response or complete response and subsequently experience disease progression will have an option to receive second course of conditioning chemotherapy therapy and axicabtagene ciloleucel. Participants will receive the same axicabtagene ciloleucel regimen as the original target dose anytime during the study. Axicabtagene Ciloleucel Fludarabine Participants will receive cyclophosphamide 500 mg/m\^2/day intravenously (IV) and fludarabine 30 mg/m\^2/day IV conditioning chemotherapy for 3 days followed by axicabtagene ciloleucel administered as a single IV infusion at a target dose of 2 x 10\^6 anti-cluster of differentiation (CD)19 chimeric antigen receptor (CAR) transduced autologous T cells/kg on Day 0. For participants weighing ≥ 100 kg, a maximum flat dose of axicabtagene ciloleucel at 2 x 10\^8 anti-CD19 CAR T cells will be administered.

Name Time Method Complete Response (CR) Rate Per the Lugano Classification as Determined by Study Investigators Up to 4 years CR Rate is the percentage of participants with CR (complete metabolic response (CMR); complete radiological response (CRR)). CMR: positron emission tomography (PET) 5-point scale (5-PS) scores of 1 (no uptake above background), 2 (uptake ≤ mediastinum), 3 (uptake \> mediastinum but ≤ liver) with/without a residual mass); no new lesions; and no evidence of fluorodeoxyglucose (FDG)-avid disease in bone marrow (BM). CRR: target nodes/nodal masses regressed to ≤ 1.5 cm in longest transverse diameter of lesion (LDi); no extralymphatic sites of disease; absent non-measured lesion (NMLs); organ enlargement regress to normal; no new sites; and bone marrow normal by morphology.

Objective Response Rate (ORR) Per the Lugano Classification as Determined by Study Investigators Up to 4 years ORR: percentage of participants with CR (CMR;CRR) or PR (partial metabolic response (PMR); partial radiologic response (PRR)). CMR: PET 5PS scores of 1 (no uptake above background, 2 (uptake ≤mediastinum), 3 (uptake \>mediastinum but ≤liver) with/without a residual mass; no new lesions; no evidence of FDG-avid disease in BM. CRR: target nodes/nodal masses regressed to ≤1.5 cm in LDi; no extralymphatic sites of disease; absent NMLs; organ enlargement regress to normal; no new sites; bone marrow morphology normal. PMR: scores 4 (uptake moderately \>liver),5 (uptake markedly \>liver, new lesions) with reduced uptake compared with baseline and residual mass; no new lesions; responding disease at interim/residual disease at end of treatment (EOT). PRR: ≥50% decrease in sum of the product of perpendicular diameters (SPD) of up to 6 target measurable nodes and extra-nodal sites; absent/normal, regressed, but no increase of NMLs; spleen regressed by \>50% in length beyond normal; no new sites.
Duration of Response (DOR) Per the Lugano Classification Up to 4 years DOR is defined only for participants who experience an objective response after axicabtagene ciloleucel infusion and is the time from the first objective response to disease progression (PD) (Lugano classification) or death from any cause. Objective response is defined in outcome measure (OM) 2. PD is defined as a score 4 (uptake moderately \> liver) or 5 (uptake markedly \>liver and/or new lesions) with an increase in intensity of uptake from baseline; new FDG-avid foci consistent with lymphoma at interim or end of treatment assessment; new FDG-avid foci consistent with lymphoma rather than another etiology (eg, infection, inflammation); new or recurrent FDG-avid foci in bone marrow. Kaplan-Meier (KM) estimates were used for analysis.
Event-Free Survival (EFS) Up to 4 years EFS was defined as the time from axicabtagene ciloleucel infusion date to earliest date of disease progression (Lugano classification), commencement of subsequent new anti-lymphoma therapy including stem cell transplant, or death from any cause. PD is defined in OM 3. KM estimates were used for analysis.
Progression-Free Survival (PFS) Up to 4 years PFS was defined as the time from axicabtagene ciloleucel infusion date to the date of disease progression per Lugano classification or death from any cause. PD is defined in OM 3. KM estimates were used for analysis.
Overall Survival (OS) Up to 4 years OS is defined as the time from axicabtagene ciloleucel infusion to the date of death from any cause. KM estimates were used for analysis.
Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (SAE) Up to 2 years An AE was any untoward medical occurrence in a participant in a clinical trial participant, which did not necessarily have a causal relationship with the treatment. Treatment-emergent adverse events were defined as any adverse event with onset on or after the axicabtagene ciloleucel infusion. Serious adverse event was defined as an event that resulted in the following: death; life-threatening situation; in-patient hospitalization or prolongation of existing hospitalization; persistent or significant disability or incapacity; congenital anomaly or birth defect; and medically important event or reaction.
Percentage of Participants Experiencing Laboratory Toxicity Grade Shifts to Grade 3 or Higher Resulting From Increased Parameter Value Up to 2 years Grading categories were determined by Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
Percentage of Participants Experiencing Laboratory Toxicity Grade Shifts to Grade 3 or Higher Resulting From Decreased Parameter Value Up to 2 years Grading categories were determined by CTCAE version 5.0.
Relapse With Central Nervous System (CNS) Disease Up to 4 years Relapse with CNS disease was defined as the time from the axicabtagene ciloleucel infusion date to the earliest date of CNS involvement with lymphoma as determined by typical symptoms, cerebrospinal fluid (CSF) evaluation, and/or diagnostic imaging.
Time to Peak Serum Level of Granzyme B, Interferon-gamma (IFNg), Interleukin (IL)-2, IL-5, IL-6, IL-8, CRP, and Ferritin Up to Week 4 Time to peak is defined as the number of days from axicabtagene ciloleucel infusion to the date when the cytokine first reached the maximum post-baseline level.
