This multi-center study open-label trial will enroll a single cohort of relapsed/refractory
diffuse large B cell lymphoma (DLBCL) patients whom are ineligible for autologous stem cell
transplant (ASCT) due to 1) insensitivity to salvage chemotherapy, or 2) inability to
tolerate high-dose myeloablative chemotherapy. All patients will receive dual checkpoint
blocking antibody (DCBA) therapy with established doses currently being used in phase III
trials of ipilimumab (1mg/kg) and nivolumab (3mg/kg) given at three week intervals, two times
before, and two times following "immunotransplant" in which T cells (in whole PBMCs) are
cryopreserved and re-infused (adoptive T cell transfer or ATCT) following lymphodepleting
chemotherapy regimen, currently being employed in adoptive T cell therapies.
1. Have pathologically confirmed DLBCL on biopsy.
2. Be willing and able to provide written informed consent/assent for the trial.
3. Be ≥18 years of age on day of signing informed consent
4. Have a performance status of 0, 1, or 2 on the ECOG Performance Scale
5. Demonstrate adequate organ function at time of screening as defined in Table 2 below,
all screening labs should be performed within 14 days of treatment initiation.

b Creatinine clearance should be calculated per institutional standard.
6. Female subject of childbearing potential should have a negative urine or serum
pregnancy within 72 hours prior to receiving the first dose of DCBA. If the urine test
is positive or cannot be confirmed as negative, a serum pregnancy test will be
7. Female subjects of childbearing potential must be willing to use an adequate method of
contraception. Contraception should be used for the course of the study through 120
days after the last dose of study medication.
Note: Abstinence is acceptable if this is the usual lifestyle and preferred
contraception for the subject.
8. Male subjects of childbearing potential must agree to use an adequate method of
contraception. Contraception, starting with the first dose of study therapy through
120 days after the last dose of study therapy.
9. Patients who did not achieve a PR or CR as per the Lugano criteria following at least
1 cycle of platinum-based salvage chemotherapy, or patients not eligible for
platinum-based therapy or BEAM induction therapy due to decreased ejection fraction
10. There is no upper age restriction.
11. Patients whom have undergone previous autologous stem cell transplant, and have
recurrent or residual disease are eligible for this trial.
The subject must be excluded from participating in the trial if the subject:
1. Is currently participating and receiving study therapy or has participated in a study
of an investigational agent and received study therapy or used an investigational
device within 28 days of the first dose of treatment.
2. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any
other form of immunosuppressive therapy within 7 days prior to the first dose of trial
3. Has a known history of active TB (Bacillus Tuberculosis)
4. Hypersensitivity to ipilimumab or nivolumab or any of their excipients.
5. Has had a prior anti-cancer monoclonal antibody (mAb) within 28 days prior to study
Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events
due to agents administered more than 28 days earlier.
6. Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy
within 14 days prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at
baseline) from adverse events due to a previously administered agent.
Note: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion and may
qualify for the study.
Note: If subject received major surgery, they must have recovered adequately from the
toxicity and/or complications from the intervention prior to starting therapy.
7. Has a known additional malignancy that is progressing or requires active treatment.
Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the
skin that has undergone potentially curative therapy or in situ cervical cancer.
8. Has known active central nervous system (CNS) metastases and/or lymphomatous
meningitis. Subjects with previously treated brain metastases may participate provided
they are stable (without evidence of progression by imaging for at least 28 days prior
to the first dose of trial treatment and any neurologic symptoms have returned to
baseline), have no evidence of new or enlarging brain metastases, and are not using
steroids for at least 7 days prior to trial treatment. This exception does not include
lymphomatous meningitis, which is excluded regardless of clinical stability.
9. Has active autoimmune disease that has required systemic treatment in the past 1 year
(i.e. with use of disease modifying agents, corticosteroids or immunosuppressive
drugs). Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid
replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a
systemic treatment. Subjects on stable dose of corticosteroids less than or equivalent
to 10mg of prednisone daily for more than 3 months may be enrolled, and continue their
stable dose through treatment.
10. Has known history of, or any evidence of active, non-infectious pneumonitis.
11. Has an active infection requiring systemic therapy.
12. Has a history or current evidence of any condition, therapy, or laboratory abnormality
that might confound the results of the trial, interfere with the subject's
participation for the full duration of the trial, or is not in the best interest of
the subject to participate, in the opinion of the treating Investigator.
13. Has known psychiatric or substance abuse disorders that would interfere with
cooperation with the requirements of the trial.
14. Is pregnant or breastfeeding, or expecting to conceive or father children within the
projected duration of the trial, starting with the pre-screening or screening visit
through 120 days after the last dose of trial treatment (roughly two and a half years
15. HIV positive with detectable viral load, or anyone not on stable anti-viral (HAART)
16. Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA
[qualitative] is detected).
17. History of allogeneic stem-cell (or other organ) transplantation.
18. Has received a live vaccine within 30 days of planned start of study therapy. Note:
Seasonal influenza vaccines for injection are generally inactivated flu vaccines and
are allowed; however intranasal influenza vaccines (e.g., Flu-Mist®) are live
attenuated vaccines, and are not allowed.
