This phase I trial evaluates the side effects of NT-I7 in treating patients with squamous cell carcinoma of head and neck that has come back (recurrent) who are undergoing surgery. NT-I7 is an immunotherapy drug that works by helping the immune system fight tumor cells. The body produces T-cells which play an important role in body's immune response and its ability to recognize tumor cells. This immunotherapy drug may boost body's T-cells to help fight cancer and enhance body's response to cancer.
PRIMARY OBJECTIVE:
I. To evaluate safety and feasibility of a single intramuscular injection of efineptakin alfa (NT-I7) in patients with locally recurrent squamous cell carcinoma of head and neck (SCCHN).
SECONDARY OBJECTIVES:
I. To describe changes in absolute lymphocyte count (ALC) in peripheral blood after a single dose of NT-I7.
II. To describe changes in tumor infiltrating lymphocytes (TIL) in tumor microenvironment of surgical specimen after a single dose of NT-I7.
III. To evaluate changes in immune subsets in peripheral blood after a single dose of NT-I7 and after surgery.
EXPLORATORY OBJECTIVE:
I. To make assessment of exploratory biomarkers for pharmacodynamic activity of NT-I7 in peripheral blood, and/or tumor tissue.
OUTLINE:
Patients receive one dose of efineptakin alfa intramuscularly (IM).
After completion of study treatment, patients are followed up for 35 days after dose or 21 days after surgery.
6,741 studies on the registry are indexed under Carcinoma; 1,161 are open to participants now.
This study's enrollment of 4 is below the median of 45 across 5,170 interventional studies indexed under Carcinoma.

Exclusion Criteria:
Patients receive one dose of efineptakin alfa IM.
Biological: Efineptakin alfa
Given via intramuscular injection
Also known as: GX-I7, Hyleukin-7 (TM), Il-7 Hybrid Fc, IL-7-hyFc, NT-I7, rhIL-7-hyFc, TJ 107, TJ-107, TJ107
Proportion of treatment-related adverse events
The proportion of patients experiencing grade 3 or 4 adverse events assessed according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 will be reported with exact binomial 95% confidence intervals. Safety analyses will be performed for all patients who receive a dose of NT-I7
Time frame: Up to 35 days after the after the NT-I7 injection
Number of participants who completed course of NT-I7
Feasibility will be evaluated as the successful completion of pre-operative NT-I7 and proceeding to pre-planned surgery without any extended treatment-related delay defined as \> 28 days from day 15. A probability-based decision rule for the study will be used to decide if the probability of successfully proceeding to surgery as planned is convincingly less than .75
Time frame: Up to 43 days after the after the NT-I7 injection
Changes in Absolute lymphocyte count (ALC)
Descriptive changes in ALC in peripheral blood both before and after a single dose of NT-I7 will be recorded.
Time frame: Up to 36 days after the NT-I7 injection
Changes in Tumor infiltrating lymphocytes (TIL)
Descriptive changes in tumor infiltrating lymphocytes in tumour microenvironment (TME) after a single dose of NT-I7 in pre-treatment biopsy and surgical specimen will be recorded.
Time frame: Up to 15 days after the NT-I7 injection
Changes in immune phenotyping
Descriptive changes in immune phenotyping in peripheral blood after a single dose of NT-I7 and after surgery as measured by mass cytometry will be recorded.
Time frame: Up to 36 days after the NT-I7 injection
Gene expression profiling: ribonucleic acid (RNA)-sequencing
Gene expression profiling by bulk ribonucleic acid (RNA)-sequencing or single cell RNA sequencing will be performed.
Time frame: Up to 36 days after the NT-I7 injection
Gene expression profiling: T cell receptor (TCR)
Gene expression profiling by T cell receptor (TCR) diversity via TCR sequencing (TCRseq) will be performed.
Time frame: Up to 36 days after the NT-I7 injection
Circulating cytokine analysis
Circulating cytokine analysis will be performed on serum samples.
Time frame: Up to 36 days after the NT-I7 injection
