Study: NCT03321903

Intervention type: DEVICE
Intervention: Carlo Erba Ink Injection
Description: Carlo Erba India ink is used in this study as a paramagnetic oxygen sensor that is injected into tissue, and which, when measured using EPR Oximetry, can provide sensitive, repeated, and direct measurements of tissue oxygen. Each study participant will receive at least one ink injection of 20-50µL of Carlo Erba India Ink. The ink injection will occur within 5mm of the body surface (i.e., skin or mucosa), and may be injected into tumor, postsurgical field of radiation, and/or adjacent normal tissue. Carlo Erba Ink is an aqueous suspension composed of charcoal powder, water for injection, and a suspending agent. Carlo Erba is the name of the manufacturer that supplies the charcoal.

Intervention type: OTHER
Intervention: EPR Oximetry Measurement
Description: An oximetry measurement visit consists of \~ 30 minutes of continuous scans of tissue oxygen in vivo, using an oxygen sensor (i.e., India ink) injected into the tumor that is noninvasively scanned using EPR oximetry. Scans, converted into measurements of pO2, characterize the current tumor oxygen level at: (1) 'steady state' (while breathing room air), 2) response to hyperoxygenation therapy (inhaling oxygen-enriched air for 10 min), and 3) response to resuming inhaling room air. EPR measurements are repeated noninvasively throughout radiation or chemotherapy, to examine changes. The minimum number of visits depends on the patient's cohort; all may have additional measurements. If the ink injection is not surgically removed, EPR oximetry measurements can be repeated indefinitely.
