Notably, TCE treatment has no major effect on tumor-reactive CD8 TILs. Our results suggest that rhIL-7-hyFc treatment promotes the antitumor efficacy of TCE immunotherapy by increasing TCE-sensitive bystander CD8 TILs in solid tumors.

rhIL-7-hyFc can expand and maintain the progenitor pool of exhausted CD8+ T cells, whereas hIL-2/TCB2c promotes their differentiation into TEX term. Together, this induces an immune-stimulatory TME that improves the efficacy of checkpoint blockade.

To evaluate the impact of CD2 on CAR-T function, we generated CD19 CAR-T cells (UCART19) with or without CD2 deletion, single-cell secretome analysis revealed that CD2 deletion in UCART19 reduced frequencies of the effector cytokines (Granzyme-B and IFN-γ). Treatment with rhIL-7-hyFc prolonged UCART2 persistence and increased survival in both the tumor re-challenge model and primary patient T-ALL model in vivo. Together, these data suggest that allogeneic fratricide-resistant UCART2, in combination with rhIL-7-hyFc, could be a suitable approach for treating T-cell malignancies.

Timing the oncolytic ZIKV injection with the peak in peripheral CD8+ T-cells greatly improved survival in the immunotherapy resistant SB28 glioma model. These data suggest a role for NT-I7 as an adjunct to various T-cell mediated treatment strategies for GBM.

This study opened in Jan 2023. Six (6) of the planned thirty (30) patients had been enrolled by time of submission.

Conclusions NT-I7-driven T cell expansion, even when combined with an anti-PD-1 agent like pembrolizumab, promotes stemness and restores T cell fitness in heavily pretreated subjects showing signs of immune dysfunction. Combining NT-I7 with conventional immunotherapy or other anticancer agents has added systemic benefits that could impact long-term clinical response in these patients.

In recent years, the progression-free survival and overall survival of patients suffering from gliomas significantly increased by introducing C7R-expressing chimeric antigen receptor (CAR)-T cells and long-acting IL-7 agonists such as NT-I7 (rhIL-7-hyFc, Efineptakin alfa)...This article first reviews the pathophysiological roles of IL-7/IL-7R in tumors, focusing on gliomas. Subsequently, it discusses the therapeutic values of IL-7/IL-7R and the recombinant derivatives in gliomas.

Further, in CRS in vitro assays, CAR-iNKT induced less IL-6 than CAR-T, suggesting reduced likelihood for CAR-iNKT cell therapy to induce CRS in patients. These data suggest BCMA CAR-iNKT are potentially a safer, effective alternative to BCMA-CAR-T and BCMA CAR-iNKT efficacy is further potentiated with rhIL-7-hyFc.

NT-I7 as an adjuvant to a DNA neoantigen vaccine increases the magnitude and duration of neoantigen-specific anti-tumor immunity in a murine model. Clinical application of NT-I7 may help overcome immunologic shortcomings of current neoantigen vaccines.
