Criteria

Inclusion Criteria:

- STEP 1: REGISTRATION: Participants must have a histologically confirmed diagnosis of
diffuse large B-cell lymphoma or follicular lymphoma grade 3b or primary mediastinal
large B-cell lymphoma (PMBCL)

- STEP 1: REGISTRATION: Participants with transformed DLBCL must have transformed DLBCL
from follicular or marginal zone lymphoma

- STEP 1: REGISTRATION: Participant must have bi-dimensionally measurable systemic
disease (at least one lesion with longest diameter > 1.5 cm)

- STEP 1: REGISTRATION: Participants with secondary central nervous system (CNS)
lymphoma (parenchymal, spinal cord, meningeal, cerebrospinal fluid involvement) must
be asymptomatic from their CNS disease

- STEP 1: REGISTRATION: Participants must be registered for step 1 after they have
signed institutional consent for CAR T-cell leukapheresis but prior to the start of
lymphodepleting (LD) chemotherapy for commercial CAR T-cell product

- STEP 1: REGISTRATION: In the opinion of the enrolling physician, participants must be
felt to be a candidate for CAR T-cell therapy with plans to be treated with Food and
Drug Administration (FDA) approved commercially available CD19 CAR T-cell construct.

- Participants must qualify for commercially approved CD19 CAR T-cell therapy per
FDA package insert.

- If the CAR T-cell product does not meet parameters to be given as an FDA approved
product (i.e. does not meet specification criteria mandated by FDA and is infused
under an expanded access protocol [EAP] or single participant investigational new
drug [IND]) the participant will be taken off of study and no longer be eligible
for step 2 randomization

- STEP 1: REGISTRATION: Participants are permitted to receive or have received 'bridging
therapy' after CAR T-cell leukapheresis. However, participants must not receive
polatuzumab vedotin, and/or mosunetuzumab as part of bridging therapy.

- Bridging therapy is defined as lymphoma directed therapy administered between
leukapheresis and the start of LD chemotherapy. This includes cytotoxic
chemotherapy (e.g.: bendamustine and rituximab [BR], rituximab, gemcitabine and
oxaliplatin [R-gem/ox]), radiation, corticosteroids, as well as novel therapies
such as BTK inhibitors (e.g.: Ibrutinib), immunomodulators (e.g.: lenalidomide),
monoclonal antibodies (e.g.: rituximab, obinutuzumab, tafasitamab) antibody drug
conjugates (e.g: loncastuximab), checkpoint inhibitors (e.g.: pembrolizumab,
nivolumab), clinical trial treatments, etc.

- If a participant receives polatuzumab vedotin or mosunetuzumab as bridging they
will ineligible to continue on step 1 registration portion of the study and be
ineligible for step 2 randomization

- STEP 1: REGISTRATION: PET-CT scan must be planned for completion within 60 days prior
to the start of LD chemotherapy.

- All pre-CAR T-cell therapy disease must be assessed and documented on the
baseline/pre-registration tumor assessment form.

completion of all planned bridging therapy. If the PET-CT scan after completion
of bridging therapy is consistent with complete remission per Lugano criteria as
determined by enrolling physician, that participant will be ineligible for step 2
randomization.

- Participants are permitted to receive corticosteroids after leukapheresis without
the need to repeat a PET-CT scan. If steroids are used, they must be planned to
stop no later than 3 days before CAR -T cell infusion.

- If response assessment by central review cannot be completed (I.e., poor quality
of PET-CT scan, PET-CT performed out of window, etc.) this would be recorded as
'inadequate assessment' and patient would not be eligible for randomization

- STEP 1: REGISTRATION: Participants that have previously been treated with polatuzumab
vedotin or mosunetuzumab prior to CAR T-cell leukapheresis for either indolent or
aggressive NHL are eligible as long as the participant did not have refractory disease
or progression/relapse within 6 months of the last infusion with either agent

- STEP 1: REGISTRATION: Participants must be planning to receive CAR T-cell infusion no
earlier than 2 days and no later than 14 days after completion of the last day of
