1. No response to first-line therapy (primary refractory disease); subjects who
are intolerant to first-line therapy chemotherapy are excluded OR

2. No response or relapse to second or greater lines of therapy OR

3. Relapsed after ASCT

3. Subjects must have received adequate prior therapy including at a minimum:

1. anti-CD20 monoclonal antibody unless investigator determines that tumor is CD20
negative, and

2. an anthracycline containing chemotherapy regimen;

4. No evidence, suspicion, and/or history of central nervous system (CNS) involvement
of lymphoma

5. Age 18 or older

8. Platelet count ≥75,000/μL

9. Absolute lymphocyte count ≥100/μL

10. Adequate renal, hepatic, pulmonary and cardiac function defined as:

1. Creatinine clearance (as estimated by Cockcroft Gault) ≥ 60 mL/min

2. Serum alanine aminotransferase/aspartate aminotransferase (ALT/AST) ≤2.5 upper
limit of normal (ULN)

3. Total bilirubin ≤1.5 mg/dL, except in subjects with Gilbert's syndrome.

4. Cardiac ejection fraction ≥ 50% and no evidence of pericardial effusion within
180 days provide the subject did not receive an anthracycline based treatment
or experience a cardiac event or change in performance status

5. No clinically significant pleural effusion

6. Baseline oxygen saturation >92% on room air

11. Cohort 2 inclusion criteria: Subjects whose commercial manufacture of axicabtagene
ciloleucel did not meet commercial release specification(s)

Exclusion Criteria:

1. History of malignancy other than nonmelanoma skin cancer or carcinoma in situ (e.g.
cervix, bladder, breast) or follicular lymphoma unless disease free for at least 3
years

5. History of severe, immediate hypersensitivity reaction attributed to aminoglycosides

6. Presence or suspicion 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 and after consultation with the Kite Pharma
Medical Monitor

7. History of human immunodeficiency virus (HIV) infection or acute or chronic active
hepatitis B or hepatitis C infection. Subjects with a history of hepatitis infection
must have cleared their infection as determined by standard serological and genetic
testing per current Infectious Diseases Society of America (IDSA) guidelines

8. History or presence of primary CNS lymphoma and/or CNS disorder such as seizure
disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or any
autoimmune disease with CNS involvement

9. Cohort 2 exclusion criteria: Any medical condition that, deemed by the investigator,
may interfere with assessment of safety or efficacy of study treatment
