NT-I7 is a Unique T Cell Amplifier

Interleukin-7 (IL-7) is Central to T Lymphocyte Development and Survival
IL-7 plays a key role in T cell development and survival1,2. When T cell numbers are low, IL-7 has the capacity to stimulate T cell expansion. However, as a homeostatic cytokine, IL-7 levels do not rise dramatically, and T cell recovery is often a slow process3.

IL-7 acts through the IL-7 receptor (IL-7R), which is expressed on naïve and memory CD4+ and CD8+ T cells. Thus, IL-7 promotes the proliferation, maintenance, and functionality of these key T cell subsets mediating immune responses. On the other hand, regulatory T cells, a subset involved in limiting immune responses, express low levels of IL-7R and are less reactive to IL-74.

At NeoImmuneTech, we are exploring the utility of NT-I7-related therapeutics in enhancing immune function.
NT-I7 is a More Potent, Stable, and Long-Acting Human IL-7
NT-I7 (efineptakin alfa) is a human IL-7 fusion protein that overcomes the key limitations of endogenous IL-7. NT-I7 has an IL-7 domain that directly promotes T cell development and an engineered N-terminus domain that overcomes the structural instability of IL-7 and enables mass production. 
The HyFc® domain extends the half-life of IL-7, thereby enhancing bioavailability which provides better potency and stability.

NT-I7 Boosts T Cell Numbers and Functionality to Enhance Immune Function and Potentially Provide Greater Therapeutic Benefits to Patients
At NeoImmuneTech, we focus on developing NT-I7 in immuno-oncology and infectious disease. NT-I7 utilizes multiple mechanisms to enhance immune function.

Homeostatic Proliferation

In cancer patients, NT-I7 increases the absolute lymphocyte count (ALC). In patients with pancreatic cancer, the ALC significantly increased 3-fold over baseline by week 3 and remained elevated for the duration of follow up. In patients with glioblastoma, the ALC was significantly increased even when patients were treated with chemotherapy, which is known to weaken the immune system.

Lymphocytes (ALC) increased and remain elevated even when patients were receiving chemotherapy (temozolomide, TMZ).

Among all lymphocyte types, T cells, the white blood cells that protect you from threats like cancer and infectious diseases, are increased the most. All T cell subsets increase with NT-I7, including the naïve (Tnaive), stem-cell memory (Tscm), central memory (Tcm) and effector memory (Tem & Temra). Less differentiated subsets, with better anti-cancer abilities, are increased the most.

Increased Tumor Infiltrating Lymphocytes (TIL)

After NT-I7 treatment we observe an increase of potent chemoattractants that mediate the migration of lymphocytes into the tumor. CCL19, a chemokine involved in the formation of tertiary lymphoid structures (TLS) known to correlate with better prognosis, is also significantly increased in patients after NT-I7 treatment.

Potent chemoattractants and mediators of TLS formation significantly increased after the first NT-I7+pembro dose. These chemokines recruit lymphocytes into the tumor and facilitate T cell anti-tumor activity. Analysis based on 17 evaluable patients. (*p≤0.05; **p≤0.001; ***p≤0.0001; ***p≤0.00001)

NeoImmuneTech, Phase 1, FIH study

Tumor-infiltrating lymphocytes (TILs) are not only a powerful prognostic marker but also a potential key breakthrough for anti-tumor therapy. NT-I7 consistently boosts CD8+ T cell infiltration, even in immunologically cold, hard-to-treat indications like MSS-CRC and Pancreatic cancer.

Increased T-Cell Receptor (TCR) Clonality in TIL

Subjects showed an increase in intratumoral clonality on-treatment, suggesting there is a selective expansion of certain clonotypes, potentially tumor-specific, in patients with favorable clinical outcomes.
Lymphocytes infiltrating the tumor had increased clonality, especially in patients with disease control. In most patients, the size of the top 10 on-treatment clonotypes were twice as large on-treatment compared to pre-treatment. Increased clonality of the 2 subjects with partial response is shown in this figure. Each color segment represents an individual TCR clonotype.

Induction of Stemness

Stem-cell Memory CD8+ T cells (Tscm), the CD8+ T cell subset with self-renewal capabilities that have shown better antitumor activity compared with other memory T cell subsets, significantly increase after NT-I7 treatment. Remarkably, while all T cell subsets increase by ~5-fold with treatment, NT-I7 preferentially expands the Tscm subset, with increases up to 50-fold compared to baseline levels.
Stem-cell memory CD8+ T cells (Tscm)
CD8+ Tscm absolute numbers peaked at week 3 with a 50-fold increase over baseline, while the other CD8+ T cell subset increased an average of ~5-fold. After a second dose of NT-I7 in week 6, CD8+ Tscm levels increased again. (*p≤0.05; **p ≤ 0.001; ***p ≤0.0001; ****p ≤0.00001)
