Radiographically documented measurable disease as per Lugano response criteria (i.e. LDi > 1.5 cm that is FDG avid). At least 2 weeks or 5 half-lives, whichever is shorter, must have elapsed since any prior systemic cancer therapy at the time the subject provides consent Eligible for standard of care CAR T cell therapy, specifically, relapsed or refractory large B cell lymphoma after two or more lines of systemic therapy, and subjects must have received adequate first-line therapy including at a minimum: Anti-CD20 monoclonal antibody unless investigator determines that tumor is CD20 negative, and An anthracycline containing chemotherapy regimen Patient does not have active CNS disease Patient is sufficiently stable to facilitate planned CAR T-cell therapy (e.g. not rapidly progressing on temporizing therapy, no significant compromise of vital organ functions (intubation, dialysis, requiring ICU/vasopressor support)) and has good performance status ECOG performance status 0 or 1 at enrollment Patient has not received prior adoptive T-cell immunotherapy Patient is not HIV positive Patient did not receive prior allogeneic stem cell transplant Adequate bone marrow, renal, hepatic, pulmonary and cardiac function Females of childbearing potential must have a negative serum or urine pregnancy test (females who have undergone surgical sterilization or who have been postmenopausal for at least 2 years are not considered to be of childbearing potential) Sexually active males who accept to use a condom during intercourse during treatment and for 6 months after treatment as they should not father a child in this period. A condom is required to be used also by vasectomized men (as well as during intercourse with a male partner) in order to prevent delivery of the drug via seminal fluid Must have an apheresis product of non-mobilized cells accepted for manufacturing.

Radiation to a single lesion, if additional non-irradiated PET-positive lesions are present, is allowed up to 2 weeks prior to leukapheresis (discuss with sponsor). Treatment with systemic immunostimulatory agents (including but not limited to interferon and IL-2) within 6 weeks or 5 half-lives of the drug, whichever is shorter, prior to the infusion of axicabtagene ciloleucel Prior chimeric antigen receptor therapy or other genetically modified T-cell therapy Presence of fungal, bacterial, viral, or other infection that is uncontrolled or requiring intravenous (IV) antimicrobials for management. Simple urinary tract infection (UTI) and uncomplicated bacterial pharyngitis are permitted if responding to active treatment.

Outcomes

Primary Outcome Measures

safety and tolerability of chemo rads as conditioning chemo
To assess the safety and tolerability of a combination chemo-radiation lymphodepletion (LD) regimen (Fludarabine (Flu)/Cyclophosphamide (Cy) + total lymphoid irradiation (TLI ) in patients receiving standard of care CAR T cell therapy for relapsed/refractory diffuse large B cell lymphoma (R/R DLBCL), by establishing the maximum tolerated doses (MTD) of standard (ZUMA-1) dose Flu/Cy + TLI, and of intermediate dose iCy/Flu +/- TLI, and the dose limiting toxicities (DLT) of standard dose Flu/Cy + TLI, and of intermediate dose iCy/Flu +/- TLI

Secondary Outcome Measures

Overall response rate
The overall response rate is the proportion of patients with either a CR or PR while on study. All patients who do not meet the criteria for objective response by the analysis data cutoff date will be considered non-responders. This will be measured by CT/PET
Complete response
To assess the efficacy (complete response (CR) rate at 12 months) of a combination chemo-radiation LD regimen (standard dose Flu/Cy + TLI) in patients receiving CAR T cell therapy for R/R DLBCL. To assess the efficacy of an intermediate dose iCy/Flu +/- TLI LD regimen in patients receiving CAR T cell therapy for R/R DLBCL. All CR and PR responses may be reviewed by an expert(s) / independent radiologist as required by simultaneous review of patient files and radiologic images
Progression free survival
To assess the efficacy (progression free survival (PFS) at 12 months) of a combination chemo-radiation LD regimen (standard dose Flu/Cy + TLI) in patients receiving CAR T cell therapy for R/R DLBCL. To assess the efficacy of an intermediate dose iCy/Flu +/- TLI LD regimen in patients receiving CAR T cell therapy for R/R DLBCL. Progression free survival (PFS) is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first.

5. Study Description

Brief Summary
This is a Phase 1b study of participants with Diffuse Large B Cell Lymphoma (DLBCL). The purpose of this study is to identify an optimized lymphodenpletion (LD) regimen by evaluating standard and intermediate doses of Fludarabine (Flu) / Cyclophosphamide (Cy) with or without a fixed dose of total lymphoid irradiation (TLI) in the setting of standard of care CAR T cell therapy.
Detailed Description
Patients will be enrolled in two stages: the dose escalation stage to assess the safety and tolerability of a modified LD regimen, and once the maximum tolerated dose (MTD) is determined, a cohort expansion phase to further characterize the toxicity and efficacy profile and determine the recommended phase 2 dose (RP2D). The study will enroll approximately 18-24 patients in the dose escalation stage (Part 1), and approximately 20 further patients at cohort expansion (Part 2). There will be four dose escalation cohorts, in two study arms. There are two dosing cohorts in each study arm. Patients in Arm 1 will receive the ZUMA-1 chemotherapy LD regimen with or without TLI, and in Arm 2, an intermediate dose of Cy with a fixed dose of Flu, with or without TLI, will be given. The cohorts in Arm 1 will enroll concurrently, and enrollment into Arm 2 will begin after Arm 1 has enrolled all patients and data review by the Trial Steering Committee (TSC). For accrual into Cohort 2, Arm 1, there will be a 15-day staggered enrollment for the first 2 patients. Staggered enrollment with another 15-day delay may be considered for enrollment into Cohorts 3 and 4, Arm 2, after review by the TSC. Following completion of accrual to Arm 1, a 30 day dose-limiting toxicity (DLT) window will be observed, prior to review by the TSC and commencement of enrollment into Arm 2.
