NT-I7 (Efineptakin Alfa), a Long-acting Human IL-7, Post-Axicabtagene Ciloleucel or Post-Lisocabtagene Maraleucel in Subjects With Relapsed/Refractory Large B-cell Lymphoma
NCT07052305 · View on ClinicalTrials.gov ↗
Study Summary
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. 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. This study is testing the hypothesis that the administration of NT-I7 following standard of care (SOC) approved CD19 CAR T-cell therapies for subjects with relapsed/refractory large B-cell lymphoma (LBCL) will be safe and tolerable and may increase the expansion and persistence of CAR T-cells in vivo, which may result in increased tumor response rate and improved clinical outcomes.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT07052305
The ClinicalTrials.gov registry entry for NCT07052305 describes a study currently listed as recruiting. It is categorized as Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 24 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Washington University School of Medicine, which has 1,036 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Large B-cell Lymphoma appearing as the primary indexed condition, and to 2 interventions — of which NT-I7 is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT07052305 reports 1 study location spanning 1 distinct geographic area — top geographies include Missouri. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
