DLBCL, NOS,
FL grade 3B,
Primary mediastinal large B cell lymphoma (PMBCL),
T cell rich/histiocyte rich large B cell lymphoma (T/HRBCL),
DLBCL associated with chronic inflammation,
Intravascular large B-cell lymphoma,
ALK+ large B-cell lymphoma,
B-cell lymphoma, unclassifiable, (with features intermediate between DLBCL and classical Hodgkin's Lymphoma (HL)),
High grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements,
High-grade B-cell lymphoma, NOS
HHV8+ DLBCL, NOS
DLBCL transforming from follicular lymphoma
DLBCL transforming from marginal zone lymphoma
DLBCL, leg type
Relapse or progression within 365 days from last dose of anti CD20 antibody and anthracycline containing first line immunochemotherapy or refractory (have not achieved a CR).
Patient is considered eligible for autologous HSCT as per local investigator assessment. Note: Intention to transplant and type of high dose chemotherapy (HDCT) regimen will be documented at the time of study entry

Disease that is both active on PET scan (defined as 5-Deauville scorepoint-scale of 4 or 5) and measurable on CT scan, defined as::

Nodal lesions >15 mm in the long axis, regardless of the length of the short axis, and/or
Extranodal lesions (outside lymph node or nodal mass, but including liver and spleen) >10 mm in long AND short axis
Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1

Adequate organ function:

Renal function defined as:

Serum creatinine of ≤1.5 x upper limit of normal (ULN), OR estimated glomerular filtration rate (eGFR) ≥ 60 mL/min/1.73 m2

Hepatic function defined as:

Alanine Transaminase (ALT) and Aspartate Transiminase (AST) ≤ 5 × ULN

Total bilirubin ≤ 1.5 x ULN with the exception of patients with Gilbert syndrome who may be included if their total bilirubin is ≤3.0 × ULN and direct bilirubin ≤1.5 × ULN

Hematologic Function (regardless of transfusions) defined as:

Absolute neutrophil count (ANC) >1000/mm3
Absolute lymphocyte count (ALC) >300/mm3 OR Absolute number of CD3+ T cells >150/mm3 (only for patients with non-historical apheresis)
Platelets ≥50000/mm3

Hemoglobin >8.0 g/dl

Adequate pulmonary function defined as:

No or mild dyspnea (≤ Grade 1)
Oxygen saturation measured by pulse oximetry > 90% on room air
Forced expiratory volume in 1 s (FEV1) ≥ 50% and/or carbon monoxide diffusion test (DLCO) ≥50% of predicted level
Must have a leukapheresis material of non-mobilized cells available for manufacturing.

Exclusion Criteria:

Prior treatment with anti-CD19 therapy, T cell therapy, or any prior gene therapy product
Treatment with any systemic lymphoma-directed second line anticancer therapy prior to randomization. Only steroids and local irradiation are permitted for disease control
Patients with active central nervous system (CNS) involvement by disease under study are excluded, except if the CNS involvement has been effectively treated and local treatment was >4 weeks before randomization
Prior allogeneic HSCT
Clinically significant active infection

Any of the following cardiovascular conditions:

Unstable angina, myocardial infarction, coronary artery bypass graft (CABG), or stroke within 6 months prior to screening,
Left ventricle ejection fraction (LVEF) <45% as determined by echocardiogram (ECHO) or magnetic resonance angiography (MRA) or multigated acquisition (MUGA) at the screening assessment.
New York Heart Association (NYHA) functional class III or IV (Chavey et al 2001), within the past 12 months.
Clinically significant cardiac arrhythmias (e.g., ventricular tachycardia), complete left bundle branch block, high-grade atrioventricular (AV) block (e.g., bifascicular block, Mobitz type II) and third degree AV block unless adequately controlled by pacemaker implantation.
Resting QTcF ≥450 msec (male) or ≥460 msec (female) at screening or inability to determine the QTcF interval
Risk factors for Torsades de Pointes (TdP), including uncorrected hypokalemia or hypomagnesemia, history of cardiac failure, or history of clinically significant/ symptomatic bradycardia, or any of the following:
Long QT syndrome, family history of idiopathic sudden death or congenital long QT syndrome
Concomitant medication(s) with a "Known Risk of Torsades de Pointes" per crediblemeds.org that cannot be discontinued or replaced by safe alternative medication.
Patients with active neurological autoimmune or inflammatory disorders (e.g., Guillain-Barré Syndrome (GBS), Amyotrophic Lateral Sclerosis (ALS)) and clinically significant active cerebrovascular disorders (e.g. cerebral edema, posterior reversible encephalopathy syndrome (PRES))

Other protocol-defined inclusion and exclusion criteria may apply.
