NCT03931655
In this spectroscopic photoacoustic imaging study, the investigators will acquire images (only) to: 1. determine if spectroscopic photoacoustic imaging can acquire high fidelity images in a clinical setting, 2. discover if blood oxygen saturation changes are observable in breast cancer patients during early stages of metastatic invasion, and 3. compare the sensitivity and specificity of photoacoustic imaging with ultrasound imaging for the detection of lymph node metastases. The results from imaging will not be used in any decision making process. This study is solely used to test the photoacoustic imaging device and evaluate it against the current standard of care. The device is completely noninvasive and uses only safe levels of energy as determined by the American National Standards Institute (ANSI) and the FDA. The device does not pose a serious to the health, safety, or welfare of the patient.
NCT04054752
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.
