following chemotherapy and radiation are eligible. Subjects with HER2 positive breast
carcinoma maintained on anti-HER2 agents after definitive therapies are also
eligible).
- Reasonable expectation that no cancer-specific therapy, with the exception noted in
the previous criteria, will be given in the subsequent 6 months (PI's discretion).

months without alternative medical cause) must use effective contraception prior
to study entry, and for 120 days after the administration of NT-I7.

participating in this study, the study participants' treating physician should be
informed immediately.
EXCLUSION CRITERIA:
- Subjects who are receiving any other investigational agents

arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements
- Significant heart disease defined as:

troponin measurement was performed.
- Ischemic changes on ECG
- Atrio-ventricular block greater than 1st degree, in absence of pacemaker
- QTc (using Fridericia and Framingham correction formula) greater than 480ms
(CTCAE 5.0 grade 1 abnormality is acceptable)
- History of ventricular arrhythmia
- Left Ventricular Ejection Fraction of less than 50% determined by
echocardiography
- Positive serology for HTLV-I or HIV, or serology findings indicative of ongoing
infection with hepatitis A, hepatitis B, or hepatitis C. Subjects with serology
findings indicative of previous exposure to hepatitis A or B vaccination will not be
excluded from Phase 1 part of the study but will be excluded from Phase 1b part of the
study (see below for additional exclusion criteria for the Phase-1b part of the study
only).
- History of autoimmune disease EXCEPT for the following: subjects with vitiligo or
endocrine disease controlled by replacement therapy including diabetes, thyroid, and
adrenal disease may be enrolled
- Subjects requiring chronic immunosuppressive therapy (including corticosteroids above
physiologic replacement dosage) for any medical condition. We will permit 1) systemic
corticosteroids at physiologic replacement dosage which are not to exceed 10 mg/day of
prednisone or an equivalent, 2) intranasal or inhaled corticosteroids, 3)
intraarticular injection of corticosteroids, 4) topical corticosteroids, 5) or a
short-term use of systemic corticosteroids greater than 10 mg/day of prednisone or an
equivalent for 10 days or less.

- Prior allogeneic hematopoietic stem cell transplantation or solid organ
transplantation
- History of medical or psychiatric disease, or cognitive impairment, which, in the view
of the principal investigator would preclude safe treatment

attributed to coagulation/bleeding disorders, documentation of abnormal coagulation
factors/platelet function studies at the discretion of PI, or those who are on
therapeutic anticoagulation
- Inability to give informed consent
- Subjects who have received immune checkpoint inhibitors in the previous 12 months, or
subjects who have received immunomodulatory drugs in the previous 4 weeks for any
medical indications. Subjects who have received intravesical BCG administration for
non-muscle invasive bladder cancer will be included in this study (i.e., not one of
exclusion criteria).
- Additional exclusion criteria for the Phase-1b part of the study only are as follows:
- Known hypersensitivity to any of the following: diphtheria toxoid, neomycin,
polymixin B, streptomycin, 2 phenoxyethanol, formaldehyde, aluminum hydroxide,
