NCT05600920 / RecruitingPhase 1/2IIT

An Open-Label, Single-Arm, Phase 1/2 Dose-Escalation Trial of Long-Acting Recombinant Human IL-7 (NT-I7, Efineptakin-Alpha) for Idiopathic CD4 Lymphopenia

Background:
Idiopathic CD4 lymphopenia (ICL) is a syndrome characterized by low levels of certain immune cells called CD4 T cells. The low CD4 T cells renders people with ICL prone to many types of severe infections, autoimmune diseases, and cancers. Although these infections and diseases can be treated whenever occur, there is currently no treatment that targeting the underlying deficiency of CD4 T cells can provide a definitive treatment for people with ICL.
Objective:
To test a new drug (NT-17) in people with ICL which can increase the number of CD4 T cells
Eligibility:
People aged 18 to 75 years with ICL who are also enrolled in NIH protocol 09-I-0102.
Design:
Participants will be screened. They will have a physical exam and blood tests. Some participants with high suspicion of central nervous system infection or history of such infections may also undergo a lumbar puncture. A thin needle will be inserted into their lower back to draw out a sample of the fluid around their spinal cord.
Participants will receive 3 doses of NT-17, each about 12 weeks apart. NT-17 is injected into the muscle of the upper arm, thigh, or buttock. They will visit the clinic 5 days before each dose and again 2 and 4 weeks after each dose. Blood will be drawn at all visits.
Participants will undergo leukapheresis 3 times. Blood will be drawn from a needle in one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be given back through a second needle in the other arm.
Some visits will include a rectal swab.
Some participants may have additional tests, including a skin exam, skin biopsies, and medical imaging.
Participants will have 3 follow-up visits every 3 months after they finish treatment.

A Phase 1/1b Study of Enhancement of Immune Reconstitution and Vaccine Responses With Administration of Recombinant Human IL-7-hyFc (NT-I7) in Older Subjects Following Chemotherapy

Background:
People with cancer, and especially older people, have a weakened immune system (the defense system of the body). This is often caused by the treatments for cancer. Older cancer survivors are therefore more prone to getting infections, some of which are preventable through vaccines. But because their immune systems are weakened, their response to vaccines is poor. Researchers want to see if a new drug, NT-I7, can help.
Objective:
To see if NT-I7 can boost the immune system.
Eligibility:
Adults 60 and older who have recently finished chemotherapy for breast, colorectal, or bladder cancer.
Design:
Participants will be screened with a physical exam, medical history, and blood and urine samples. Their heart s electrical activity will be checked. They will have an ultrasound of their spleen. They may give a tissue sample from a previous biopsy.
Participants in phase 1a of the study will get 1 dose of NT-I7. It will be given by injection with a needle into the muscle of the upper arm, thigh, or buttocks.
Participants in phase 1b will get 5 vaccines over a few months. They may get an optional booster and/or 6th vaccine. They will also get NT-I7.
Participants will repeat the screening tests during the study. They may get a peripheral intravenous catheter in a vein in their hand or arm for blood draws.
Participants may have apheresis. For this, blood is taken from an arm vein. The white blood cells are separated from the blood. The rest of the blood, minus the white blood cells, is returned into a vein in the other arm. A catheter may be used.
Participants will have follow-up visits for 1 year.

Efficacy and Safety Study of Neoadjuvant Efineptakin Alfa (NT-I7) and Pembrolizumab in Recurrent Glioblastoma

This phase II trial tests the safety and side effects of efineptakin alfa and pembrolizumab in treating patients with glioblastoma that has come back (recurrent). Efineptakin alfa is an immunotherapy drug that works by helping the immune system fight tumor cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving efineptakin alfa and pembrolizumab may kill more tumor cells in patients with recurrent glioblastoma.

rhIL-7-hyFc, a long-acting interleukin-7, improves efficacy of CAR-T cell therapy in solid tumors

Article

Author: Li, Dan ; Wolfarth, Alexandra A ; Hutchins, Laura E ; Liang, Tianyuzhou ; Lee, Byung Ha ; Ho, Mitchell ; Ferrando-Martinez, Sara

Background:

Chimeric antigen receptor T-cell (CAR-T) therapy has achieved remarkable remission in patients with B-cell malignancies. However, its efficacy in treating solid tumors remains limited. Here, we investigated a combination therapy approach using an engineered long-acting interleukin (IL)-7 (rhIL-7-hyFc or NT-I7) and CAR-T cells targeting three antigens, glypican-2 (GPC2), glypican-3 (GPC3), and mesothelin (MSLN), against multiple solid tumor types including liver cancer, neuroblastoma, ovarian cancer, and pancreatic cancer in mice.

Methods:

CAR-T cells targeting GPC2, GPC3, and MSLN were used in combination with NT-I7 to assess the anticancer activity. Xenograft tumor models, including the liver cancer orthotopic model, were established using NOD scid gamma mice engrafted with cell lines derived from hepatocellular carcinoma, neuroblastoma, ovarian cancer, and pancreatic cancer. The mice were monitored by bioluminescence in vivo tumor imaging and tumor volume measurement using a caliper. Immunophenotyping of CAR-T cells on NT-I7 stimulation was evaluated for memory markers, exhaust markers, and T-cell signaling molecules by flow cytometry and western blotting.

Results:

Compared with the IL-2 combination, preclinical evaluation of NT-I7 exhibited regression of solid tumors via enhanced occupancy of CD4+CAR-T, improved T-cell expansion, reduced exhaustion markers (programmed cell death protein 1 or PD-1 and lymphocyte-activation gene 3 or LAG-3) expression, and increased generation of stem cell-like memory CAR-T cells. The STAT5 pathway was demonstrated to be downstream of NT-I7 signaling, mediated by increased expression of the IL-7 receptor expression in CAR-T cells. Furthermore, CAR-T cells improved efficacy against tumors with low antigen density when combined with NT-I7 in mice, presenting an avenue for patients with heterogeneous antigenic profiles.

Conclusion:

This study provides a rationale for NT-I7 plus CAR-T cell combination therapy for solid tumors in humans.

IL-7-primed bystander CD8 tumor-infiltrating lymphocytes optimize the antitumor efficacy of T cell engager immunotherapy

Article

Author: Kim, Ji-Hae ; Tae, Nara ; Kim, Dae Hee ; Park, Uni ; Moon, Dain ; Choi, Donghoon ; Lee, Seung-Woo ; Sohn, Joohyuk ; Song, Ha Won ; Lee, Kun-Joo ; Hong, Da Hee ; Byun, Mi-Sun ; Yang, Jaehyuk ; Park, Su-Hyung ; Choi, Sun Shim ; Oh, Youngsik ; Jeong, Siheon ; Im, Sun-Kyoung ; Park, Sujeong ; Kang, Yeon-Woo ; Lee, Minji ; Park, Yunji

Bispecific T cell engagers (TCEs) show promising clinical efficacy in blood tumors, but their application to solid tumors remains challenging. Here, we show that Fc-fused IL-7 (rhIL-7-hyFc) changes the intratumoral CD8 T cell landscape, enhancing the efficacy of TCE immunotherapy. rhIL-7-hyFc induces a dramatic increase in CD8 tumor-infiltrating lymphocytes (TILs) in various solid tumors, but the majority of these cells are PD-1-negative tumor non-responsive bystander T cells. However, they are non-exhausted and central memory-phenotype CD8 T cells with high T cell receptor (TCR)-recall capacity that can be triggered by tumor antigen-specific TCEs to acquire tumoricidal activity. Single-cell transcriptome analysis reveals that rhIL-7-hyFc-induced bystander CD8 TILs transform into cycling transitional T cells by TCE redirection with decreased memory markers and increased cytotoxic molecules. 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.

Understanding the pharmacokinetic journey of Fc-fusion protein, rhIL-7-hyFc using complementary approach of two analytical methods, accelerator mass spectrometry and ELISA

Article

Author: Kim, Anhye ; Choi, Donghoon ; Song, Seongeun ; Lee, Howard ; Lee, Gwan-Ho ; Yu, Byung-Yong ; Oh, Min-Seok ; Byun, Mi-sun

Abstract:

Antibody-based therapeutics (ABTs), including monoclonal/polyclonal antibodies and fragment crystallizable region (Fc)-fusion proteins, are increasingly used in disease treatment, driving the global market growth. Understanding the pharmacokinetic (PK) properties of ABTs is crucial for their clinical effectiveness. This study investigated the PK profile and tissue distribution of efineptakin alfa, a long-acting recombinant human interleukin-7 (rhIL-7-hyFc), using enzyme-linked immunosorbent assay (ELISA) and accelerator mass spectrometry (AMS). Totally, four rats were injected intramuscularly with 1 mg/kg of rhIL-7-hyFc containing 14C-rhIL-7-hyFc, which was prepared via reductive methylation. Serum total radioactivity (TRA) and serum rhIL-7-hyFc concentrations were quantified using AMS and ELISA, respectively. The TRA concentrations in organs were determined by AMS. Serum TRA peaked at 10 hours with a terminal half-life of 40 hours. The rhIL-7-hyFc exhibited a mean peak concentration at around 17 hours and a rapid elimination with a half-life of 12.3 hours. Peak concentration and area under the curve of TRA were higher than those of rhIL-7-hyFc. Tissue distribution analysis showed an elevated TRA concentrations in lymph nodes, kidneys, and spleen, indicating rhIL-7-hyFc’s affinity for these organs. The study also simulated the positions of 14C labeling in rhIL-7-hyFc, identifying specific residues in the fragment of rhIL-7 portion, and provided the explanation of distinct analytes targeted by each method. Combining ELISA and AMS provided advantages by offering sensitivity and specificity for quantification as well as enabling the identification of analyte forms. The integrated use of ELISA and AMS offers valuable insights for the development and optimization of ABT.

Adequate cell expansion and persistence remains a key challenge that limits the efficacy of chimeric antigen receptor T (CAR-T) cell therapies New clinical results presented at ESMO 2024 show NT-I7 treatment following CAR-T cell administration is safe and well tolerated and improv es clinical outcomes through successful expansion of CAR-T cells ROCKVILLE, Md. , Sept. 9, 2024 /PRNewswire/ -- NeoImmuneTech, Inc. (NIT or "NeoImmuneTech"), a global leader in T cell-based immunotherapy, will present interim results of the Phase 1b clinical trial (NIT-112) combining a CAR-T therapy with NT-I7 (efineptakin alfa) during the 'Mini oral session 1: Haematological malignancies' at the European Society for Medical Oncology (ESMO) in Barcelona, Spain, from September 13 to 17. These initial results present a promising approach to enhancing the potential of CAR-T therapies while maintaining a stable safety profile. The NIT-112 clinical trial involves patients with Large B-cell Lymphoma (LBCL) who received CAR-T therapies such as Kymriah, Yescarta, or Breyanzi, followed by NT-I7 administration 21 days after CAR-T infusion. The trial aims to evaluate safety, tolerability, the recommended Phase 2 dose (RP2D), and the potential for NT-I7 to enhance CAR-T expansion, persistence and stemness. Interim results show that at dose levels 4 and 5, which are considered mid-level doses (360, 480 µg/kg), NT-I7 demonstrated a stable safety profile. No cases of Cytokine Release Syndrome (CRS) or Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS), which are known as high-risk side effects of CAR-T therapies, were observed subsequent to NT-I7 administration. Only mild, manageable side effects (Grade 1-2), such as injection site erythema and swelling were observed in 6 out of 11 patients (54.5%). Overall, a strong safety profile was observed. NT-I7 administration resulted in significant amplification of CAR-T cells, prolonged persistence and an increase in T cell stemness, characterized by a higher frequency of T cells with a stem-cell memory (Tscm) phenotype (CD45RA+CCR7+CD95+). The overall response rate (ORR) from the interim results was 81.1% (9 out of 11 patients), with 7 achieving a complete response (CR) and 2 achieving a partial response (PR). Kymriah is known to have an ORR of 52% in LBCL patients. Dr Luke Oh, President and Chief Executive Officer of NeoImmuneTech, Inc., said: "We are thrilled by the preliminary results of study NIT-112 showing NT-I7's ability to amplify CAR-T cells.

EMA Grants Orphan Drug Designation to NeoImmuneTech's NT-I7 for the Treatment of Acute Radiation Syndrome

This regulatory milestone marks an acceleration of the process around NT-I7's potential first indication, after other recent positive news. NeoImmuneTech's NT-I7 has shown potential in nonclinical studies to address the immunosuppressive effects of ARS. ROCKVILLE, Md. , June 4, 2024 /PRNewswire/ -- NeoImmuneTech, Inc. (NIT or "NeoImmuneTech"), a clinical-stage T cell-focused biopharmaceutical company, today announced that the European Medicines Agency (EMA) has granted Orphan Drug Designation (ODD) to NT-I7 (efineptakin alfa) for the treatment of Acute Radiation Syndrome (ARS). This regulatory milestone follows the ODD granted to NT-I7 by the FDA in the US for the same indication in November 2023. It is the second ODD received by NT-I7 from the EMA, following the one granted in Idiopathic CD4+ Lymphocytopenia (ICL) in May 2017. ARS is a critical condition resulting from a high dose of radiation exposure, causing severe, sometimes fatal damage to the bone marrow and the immune system. Currently, there are no treatments available that effectively promote T cell recovery after such exposure. NT-I7, a novel long-acting human interleukin-7 (IL-7), has shown promise to accelerate T cell reconstitution and enhance the immune response, offering a potential solution for this medical unmet need. Clinical studies have shown that NT-I7 significantly boosts T cell counts, while maintaining a high level of safety and tolerability. NeoImmuneTech is actively developing NT-I7 in ARS through partnerships with the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH) and Duke University. Recently, Duke University secured a $6 million grant from NIAID for NT-I7 development in ARS. Luke Oh, Ph.D., President and Chief Executive Officer of NeoImmuneTech, said: "We are thrilled to see the deep interest of the scientific and regulatory community around the potential use of NT-I7 as a medical countermeasure in ARS. The EMA Orphan Drug Designation marks a new milestone for us, following our recent pre-IND discussions we had with the FDA to accelerate our development program. It is an important acknowledgment of the potential that NT-I7 holds in providing a beacon of hope for the treatment of ARS." ODD is a status assigned to a medicine intended for use against a rare disease or condition. The designation provides incentives to advance the development of treatments for rare diseases, including reduced fees for multiple steps in the development process, such as protocol assistance, marketing authorization applications, and inspections before authorization. About Acute Radiation Syndrome (ARS) Acute Radiation Syndrome (ARS) is an acute illness caused by irradiation of the entire body by a high dose of penetrating radiation in a very short period of time (typically a matter of minutes or less). Examples of people who suffered from ARS are individuals exposed during the Hiroshima and Nagasaki atomic bombings, and the firefighters that responded after the Chernobyl Nuclear Power Plant incident in 1986.[1] About NT-I7 (efineptakin alfa) (rhIL-7-hyFc) NT-I7 (efineptakin alfa) is the only clinical-stage long-acting human IL-7, and is being developed in oncologic and immunologic indications, where T cell amplification and increased functionality may provide clinical benefit.

NeoImmuneTech's New Data at ASCO 2024 Highlights Enhanced Benefits of Combining NT-I7 with Checkpoint Inhibitors (CPI) in Immuno-Oncology

Results from study NIT-110 with NT-I7 and CPI combination treatment show median overall survival (mOS) improvements over standard of care treatment in pancreatic cancer and MSS colorectal cancer Correlative analysis identified potentially predictive protein biomarkers associated with patients experiencing the most clinical benefits from combination treatment of NT-I7 and CPI Combination of NT-I7 and oncolytic virus demonstrates clear survival improvement in preclinical glioblastoma results ROCKVILLE, Md., June 3, 2024 /PRNewswire/ -- NeoImmuneTech, Inc. (NIT), a T cell-focused therapeutics company, today announced promising interim results of its major clinical trial NIT-110 of NT-I7 (efineptakin alfa), at the 2024 American Society of Clinical Oncology (ASCO) global meeting held in Chicago, from May 31 to June 4. The company also presented two additional posters at the conference. NIT-110 is a foundational clinical trial for NT-I7 that aims to confirm the safety and efficacy of combining NT-I7 with pembrolizumab (Keytruda®) in solid tumors. The data presented at ASCO 2024 confirmed that the combination is safe and well-tolerated. Key findings from NIT-110 include: Pancreatic cancer - Data showed a median overall survival (mOS) of 11.1 months among the 48 pancreatic cancer patients included in the study. The mOS for pancreatic cancer patients who have received a second-line standard of care treatment is currently known to be 6.1 months[1]. This mOS improvement is particularly noteworthy considering that 93.75% of the patients are receiving the combination treatment as third-line or beyond. MSS colorectal cancer -The mOS for the 50 microsatellite-stable (MSS) colorectal cancer patients was 13.2 months. The mOS for the current standard of care treatment is 10.8 months[2]. These results underscore the improved efficacy of the NT-I7 and Keytruda combination over existing standard of care treatments. A separate poster from trial NIT-110 revealed a correlative analysis identifying a potentially predictive biomarker. These biomarkers may help identify patient populations more likely to benefit clinically from the NT-I7 and Keytruda combination. NeoImmuneTech is committed to further biomarker validation to enhance clinical outcomes. Additionally, a preclinical study presented at ASCO 2024 highlighted the combination of NT-I7 with an oncolytic virus (ZIKV) in a glioblastoma animal model. Results demonstrated a significant increase in tumor specific CD8 T cells in the tumor microenvironment, leading to improved survival rates. Furthermore, 80% of cases in the experimental group combining NT-I7 with immune checkpoint inhibitors resulted in complete tumor eradication. NT-I7 continues to show clinical benefits driven by T cell amplification when combined with immune therapies. NeoImmuneTech's CEO, Luke Oh, PhD, said: "We are very encouraged by the improved clinical efficacy over standard of care in pancreatic and colorectal cancer, a notoriously difficult to treat cancer. These findings confirm our promising preclinical data and open new pathways to further enhance clinical outcomes. We are actively discussing the next steps with Merck. The results presented at ASCO 2024 confirm our strategy to continue to develop NT-I7 in the larger and high-potential immuno-oncology market." Posters references: About Study NIT-110 NIT-110 is an open label Phase 2a clinical trial supported by Merck that aims to confirm the efficacy of combining NT-I7 with Keytruda in two solid tumors. Early results in 2022 had confirmed the efficacy of the combination in pancreatic cancer and MSS colorectal cancer patients, who are known to be unresponsive to immune checkpoint inhibitors alone. Consequently, 24 and 25 additional patients were recruited for each group, respectively, bringing the total to 48 pancreatic cancer patients and 50 MSS colorectal cancer patients currently undergoing clinical trials. Results presented at ASCO 2024 provide an updated analysis including the original and expansion cohorts.
