Vaccine Response With NT-I7

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.

Experimental PET Imaging Scans Before Cancer Surgery to Study the Amount of PET Tracer Accumulated in Normal and Cancer Tissues

This phase I trial studies a new imaging technique called FAPi PET/CT to determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulate in normal and cancer tissues in patients with non-prostate cancer. The research team also want to know whether what they see on PET/CT images represents the tumor tissue being excised from the patient's body. The research team is also interested to investigate another new imaging technique called PSMA PET/CT. Participants will be invited to undergo a second PET/CT scan, with the PSMA tracer (68Ga-PSMA-11). This is not required but just an option for volunteer patients. Patients can decide to have only the FAPI PET/CT scan. The PET/CT scanner combines the PET and the CT scanners into a single device. This device combines the anatomic (body structure) information provided by the CT scan with the metabolic information obtained from the PET scan. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of, in the case of this research, 68Ga-PSMA-11 and 68Ga-FAPi. Because some cancers take up 68Ga-PSMA-11 and/or 68Ga-FAPi it can be seen with PET. CT utilizes x-rays that traverse the body from the outside. CT images provide an exact outline of organs where it occurs in patient's body. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors. The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers. PSMA stands for Prostate Specific Membrane Antigen. This name is incorrect as PSMA is also found in many other cancers. The function of PSMA is not well understood but imaging studies have shown that PSMA can be detected with PET in many non-prostate cancers. Imaging FAP with PET/CT may in the future provide additional information about various cancers.
