A Phase 3, Randomized, Open-Label Study Evaluating the Efficacy of Axicabtagene Ciloleucel Versus Standard of Care Therapy in Subjects With Relapsed/Refractory Diffuse Large B Cell Lymphoma (ZUMA-7)
The goal of this clinical study is to assess whether axicabtagene ciloleucel therapy improves the clinical outcome compared with standard of care second-line therapy in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL).
This is a phase 3 randomized, open-label, multicenter study evaluating the efficacy of
axicabtagene ciloleucel versus standard of care therapy in participants with
relapsed/refractory DLBCL. Adult participants with relapsed/refractory DLBCL after first-line
rituximab and anthracycline-based chemotherapy will be randomized in a 1:1 ratio to receive
axicabtagene ciloleucel or standard of care second-line therapy.
Standard of care will consist of a protocol-defined, platinum-based salvage combination
chemotherapy regimen followed by high-dose therapy and autologous stem cell transplant in
those who respond to salvage chemotherapy. After completing the treatment period, all
participants will be followed in the post-treatment follow-up period for up to 5 years.
Thereafter, participants who received at least one dose of axicabtagene ciloleucel as
protocol therapy will transition to a separate long term follow up (LTFU) study and complete
the remainder of the 15-year follow-up assessments within KT-US-982-5968 (NCT05041309).

germinal center B-cell (ABC/GCB).
- High-grade B-cell lymphoma (HGBL) with or without myelocytomatosis oncogene (MYC)
and B-cell lymphoma (BCL) 2 and/or BCL6 rearrangement.

- DLBCL associated with chronic inflammation.
- Primary cutaneous DLBCL, leg type.
- Epstein-Barr virus (EBV) + DLBCL.
- Relapsed or refractory disease after first-line chemoimmunotherapy.
- Refractory disease defined as no complete remission to first-line therapy;
individuals who are intolerant to first-line therapy are excluded.
- Progressive disease (PD) as best response to first-line therapy.
- Stable disease (SD) as best response after at least 4 cycles of first-line
therapy (eg, 4 cycles of R-CHOP).
- Partial response (PR) as best response after at least 6 cycles and
biopsy-proven residual disease or disease progression ≤ 12 months of
therapy.
- Relapsed disease defined as complete remission to first-line therapy followed by
biopsy-proven relapse ≤ 12 months of first-line therapy.
- Individuals must have received adequate first-line therapy including at a minimum:
- Anti-Cluster of Differentiation antigen (CD) 20 monoclonal antibody unless
investigator determines that tumor is CD20 negative, and
- An anthracycline containing chemotherapy regimen.
- No known history or suspicion of central nervous system involvement by lymphoma.
- Eastern cooperative oncology group (ECOG) performance status of 0 or 1.
- Adequate bone marrow function as evidenced by:
- Absolute neutrophil count (ANC) ≥ 1000/uL
- Platelet ≥ 75,000/uL
- Absolute lymphocyte count ≥ 100/uL
- Adequate renal, hepatic, cardiac, and pulmonary function as evidenced by:
- Creatinine clearance (Cockcroft Gault) ≥ 60 mL/min.
- Serum Alanine aminotransferase/Aspartate aminotransferase (ALT/AST) ≤ 2.5 Upper
limit of normal (ULN).
- Total bilirubin ≤ 1.5 mg/dl
- Cardiac ejection fraction ≥ 50%, no evidence of pericardial effusion as
determined by an Echocardiogram (ECHO), and no clinically significant
Electrocardiogram (ECG) findings.
- No clinically significant pleural effusion.
- Baseline oxygen saturation > 92% on room air.
Key Exclusion Criteria:
- History of malignancy other than nonmelanoma skin cancer or carcinoma in situ (eg
cervix, bladder, breast) unless disease free for at least 3 years.
- Received more than one line of therapy for DLBCL.
- History of autologous or allogeneic stem cell transplant.
- Presence of fungal, bacterial, viral, or other infection that is uncontrolled or
requiring intravenous antimicrobials for management.
- Known history of infection with human immunodeficiency virus (HIV) or hepatitis B
(HBsAg positive) or hepatitis C virus (anti-HCV positive). If there is a positive
history of treated hepatitis B or hepatitis C, the viral load must be undetectable per
quantitative polymerase chain reaction (PCR) and/or nucleic acid testing.
- Individuals with detectable cerebrospinal fluid malignant cells or known brain
metastases, or with a history of cerebrospinal fluid malignant cells or brain
metastases.
- History or presence of non-malignant central nervous system (CNS) disorder such as
seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease,
or any autoimmune disease with CNS involvement.
- Presence of any indwelling line or drain. Dedicated central venous access catheter
such as a Port-a-Cath or Hickman catheter are permitted.
- History of myocardial infarction, cardiac angioplasty or stenting, unstable angina,
New York Heart Association Class II or greater congestive heart failure, or other
clinically significant cardiac diseases within 12 months of enrollment.
- History of symptomatic deep vein thrombosis or pulmonary embolism within 6 months of
enrollment.
- History of autoimmune disease, requiring systemic immunosuppression and/or systemic
disease modifying agents within the last 2 years.
- History of anti-CD19 or CAR-T therapy or history of prior randomization in ZUMA-7.
