failure is defined as either failure to achieve an objective response (PR or

to receive ASCT treatment (due to age or other factors) are eligible; the reason
for not receiving ASCT must be documented in the electronic case report form
(eCRF).
5. Positron emission tomography (PET)-positive disease as per the Lugano Classification

8. Adequate vascular access for leukapheresis.
9. Willing and able to undergo tumor biopsies (in subjects with accessible disease).
10. Agree to not donate blood, organs, sperm or semen, and egg cells for usage in other
individuals as detailed in the protocol.
11. Female and male subjects agree to use effective contraception as detailed in the
protocol.
Exclusion Criteria:
The presence of any of the following will exclude a subject from enrollment:
1. Uncontrolled medical, psychological, familial, sociological, or geographical
conditions that do not permit compliance with the protocol, as judged by the
Investigator; or unwillingness or inability to follow the procedures required in the
protocol.
2. Any condition including the presence of laboratory abnormalities, which places the
subject at unacceptable risk if he/she were to participate in the study.
3. Any condition that confounds the ability to interpret data from the study.
4. Central nervous system (CNS)-only involvement by malignancy (note: subjects with
pathologically-confirmed secondary CNS involvement are allowed).)
5. Prior CAR T- cell or genetically-modified T- cell therapy, or prior CD19- targeted
therapy (including, but not limited to, anti-CD19 mAbs or bispecific antibodies).)
6. Treatment with the following therapies or procedure within the specified period:
1. Therapeutic doses of corticosteroids (defined as > 20 mg/day prednisone or
equivalent) within 14 days before leukapheresis administration. Physiologic
replacement, topical, and inhaled steroids are permitted.
2. Cytotoxic chemotherapeutic agents (eg, doxorubicin, vincristine, gemcitabine,
oxaliplatin, carboplatin, etoposide) within 7 days of leukapheresis, with the
exception of alkylating agents.
3. Intrathecal therapy (eg, dexamethasone, methotrexate, cytosine arabinoside,
cytarabine) within 7 days of leukapheresis.
4. Oral chemotherapeutic agents, including lenalidomide and ibrutinib, are allowed
if at least 5 half-lives have elapsed prior to leukapheresis.
5. Alkylating agents (eg, cyclophosphamide, ifosfamide, bendamustine) within 4 weeks
of leukapheresis.
6. Any experimental therapy within 8 weeks (for biologics) or 5 half-lives (for
small molecules) before leukapheresis
7. Immunosuppressive therapies within 4 weeks of leukapheresis (eg, calcineurin
inhibitors, methotrexate or other chemotherapeutics, mycophenolate, rapamycin,
immunosuppressive antibodies such as anti-TNF, anti-IL6, or anti-IL6R)
8. Monoclonal antibodies (including rituximab, polatuzumab, etc.) within 7 days.
9. Donor lymphocyte infusions within 6 weeks of leukapheresis
10. Radiation within 6 weeks of leukapheresis. Subjects must have progressive disease
in irradiated lesions or have additional non-irradiated, PET-positive lesions to
be eligible. Radiation to a single lesion, if additional non-irradiated
PET-positive lesions are present, is allowed up to 14 days prior to
leukapheresis.
11. Autologous stem-cell transplant (SCT) (ie, Day 0 receipt of hematopoietic stem
cells) within 3 months of leukapheresis
12. Washout of prior therapy (eg, bridging therapy for disease control)
7. Active autoimmune disease requiring immunosuppressive therapy.
8. Allogenic SCT (ie, Day 0 receipt of hematopoietic stem cells) within 6 months of
leukapheresis or presence of ongoing symptoms or treatment for chronic graft-versus
host disease (GVHD).)
9. Hypersensitivity to fludarabine and/or cyclophosphamide.
10. Prior history of malignancies, other than studied NHL, unless the subject has been
free of the disease for ≥ 2 years except for the following non-invasive malignancies:
1. Basal or squamous cell carcinoma of the skin
2. Carcinoma in situ of the cervix or the breast
3. Incidental histologic finding of prostate cancer (T1a or T1b using the TNM
(tumor, nodes, metastasis) clinical staging system) or prostate cancer that is
curative
4. Other completely resected stage 1 solid tumor with low risk for recurrence
11. Active hepatitis B, hepatitis C, or any human immunodeficiency virus (HIV) infection
at the time of screening.
12. Uncontrolled or active systemic fungal, bacterial, viral or other infection despite
appropriate anti-infection treatment at the time of leukapheresis or pre-treatment
evaluation.
13. History of any one of the following cardiovascular conditions within the 6 months
prior to screening: Class III or IV heart failure as defined by the New York Heart
Association, myocardial infarction, unstable angina, angioplasty or stenting, or other
clinically significant cardiac disease.
14. History or presence of clinically significant CNS pathology such as seizure disorder,
aphasia, stroke, severe brain injuries, dementia, Parkinson's disease, or cerebellar
disease. Presence of clinically active psychosis.
15. History of ≥ Grade 2 hemorrhage within 30 days of screening.
16. Pregnant or nursing (lactating) women.
17. Previous SARS-CoV-2 infection within 10 days for mild or asymptomatic infections or 20
days for severe/critical illness prior to leukapheresis or initiation of LD
chemotherapy.
-Acute symptoms must have resolved and based on investigator assessment in
consultation with the Sponsor Medical Monitor, there are no sequelae that would place
the subject at a higher risk of receiving study treatment.
18. Previous SARS-CoV-2 vaccine within 14 days prior to leukapheresis or initiation of LD
chemotherapy.
