NT-I7

Standard of care: Will be given on day 0 and will be either axicabtagene ciloleucel or lisocabtagene maraleucel .

NT-I7 is a long-acting human IL-7 cytokine which has been shown in nonclinical studies to increase peripheral T-cells, antitumor efficacy, and tumor infiltrating lymphocytes, either as a monotherapy or in combination with chemo/radiotherapy and/or immune checkpoint inhibitors and CAR T therapy.

Diffuse large B-cell lymphoma is the most commonly occurring subtype of non-Hodgkin lymphoma, but treatment is often not curative, with as many as 50% of patients with adverse risk factors developing relapsed/refractory disease. CAR T-cell therapy has revolutionized modern cancer therapy, with axicabtagene ciloleucel and lisocabtagene maraleucel (anti-CD19 CAR T-cell therapies) FDA approved for second- or later-line treatment of relapsed/refractory large B-cell lymphoma.

IL-7 plays a crucial role in T-cell homeostasis by inducing thymic differentiation, peripheral expansion, and extrathymic differentiation. It is the main regulator of T-cell hemostasis, inducing T-cell growth and proliferation in lymphopenic patients. There is data that suggests that exposure of T-cells to IL-7 may expand T-cells, prevent T-cell exhaustion, and improve effector functions.

Live record on ClinicalTrials.gov →

• Histologically confirmed relapsed or refractory large B-cell lymphoma, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (NOS), high grade B-cell lymphoma, DLBCL arising from an indolent lymphoma, grade 3B follicular lymphoma and primary mediastinal large B-cell lymphoma.
• Measurable disease by IWG response criteria for lymphoma.
• Baseline FDG-PET/CT scan must show FDG-avid lesions compatible with CT-defined anatomical tumor sites.
• A previously irradiated lesion can be considered a target lesion if it is well defined, measurable, and has clearly progressed following radiation.
• FDG-PET/CT scans done as SOC up to 60 days pre-lymphodepletion therapy will be allowed. NOTE: After eligibility is confirmed, restaging FDG-PET/CT scans will not be used to change eligibility.
• Eligible for treatment with an FDA-approved SOC CD19 CAR T-cell therapy respective to the current FDA-approved CAR T-cell label for axi-cel(Yescarta®) or liso-cel (Breyanzi®).
