Detailed Description
This is a multicenter Phase 1b study evaluating the safety, tolerability, and preliminary anti-tumor activity of NT-I7 administration following standard of care CD19 CAR T-cell therapy for eligible subjects with r/r LBCL. The study consists of a Dose Escalation phase followed by a Dose Expansion phase.
In the Dose Escalation phase, subjects will be enrolled in 1 of 7 dose levels, starting with 60 µg/kg and up to 720 µg/kg. A dose schedule for an individual dose level will not be taken into expansion until the Dose Escalation phase has been completed or a maximum tolerated dose (MTD) has been determined, whichever occurs first.
In the Dose Expansion phase, up to 15 subjects will be enrolled and treated with the recommended dose identified in the Dose Escalation phase.
Up to 17- 42 subjects in the Dose Escalation phase, and up to 15 subjects in the Dose Expansion phase will be enrolled at approximately 20 study centers.
Treatment Plan:
NT-I7 (aka rhIL-7-hyFc, efineptakin alpha), Tisagenlecleucel (Kymriah®), Axicabtagene ciloleucel (Yescarta®), Lisocabtagene Maraleucel (Breyanzi®)
*CAR-T Therapy will be administered per manufacturer's recommendations and in accordance with FDA prescribing guidelines and best institutional practices for standard of care use.

- Subjects should be eligible for CAR-T therapy respective to the current FDA-approved CAR-T label for Yescarta, Breyanzi, or Kymriah.
Subjects with histologically confirmed relapsed or refractory LBCL including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (NOS), high grade B-cell lymphoma,DLBCL arising from follicular lymphoma, and primary mediastinal large B-cell lymphoma, must be eligible for SOC CD19 CAR T-cell Therapy.
(a) Tumor tissue (fresh or archival) must have been tested to confirm the type of LBCL.
Subjects must have measurable disease by IWG response criteria for lymphoma [Lugano classification (3)]
- Baseline fluorodeoxyglucose (FDG)-PET/computed tomography (CT) scans must show positive lesions compatible with CT-defined anatomical tumor sites but will not be used in subsequent clinical decisions.
- A previously irradiated lesion can be considered a target lesion if the lesion is well defined, measurable, and has clearly progressed.
- Subjects that received bridging therapy pre-lymphodepletion will be allowed for enrollment regardless of re-staging results (PMR or CMR), even if the lesion is not measurable per the criteria mentioned above.
- PET/CT scans done as SOC up to 28 days pre-lymphodepletion therapy will be allowed.
All subjects whose scans are > 28 days from lymphodepletion therapy will need a re-staging FDG-PET/CT scan.

- Subjects must have a life expectancy of greater than or equal to 12 weeks per assessment from the enrolling physician.
- Adequate organ and marrow function per institutional guidelines at the start of lymphodepleting chemotherapy as pre-conditioning for SOC CD19 CAR T-cell infusion.
The following laboratory parameters (9a-h) are recommendations. Labs outside of these ranges may be considered for inclusion after consultation with the medical monitor. Cytopenia resulting from disease or bridging therapy will not be considered exclusionary.

Female subjects of childbearing potential (including women who have had a tubal ligation) must have a negative serum or urine pregnancy test within 72 hours prior to NT-I7 injection. If the urine test is positive, or cannot be confirmed as negative, a serum pregnancy test will be required.
