Overview
Brief Summary
The purpose of this study is to evaluate the safety and potential of a new experimental imaging instrument called multispectral optoacoustic tomography (MSOT) to detect inflammation in patients with chronic graft versus host disease of the skin or GI tract, Crohn's disease, or Colitis disease.
Detailed Description
This is a single arm, 3-cohort study that is designed to provide safety information regarding the use of the Acuity MSOT device in the clinical setting, and the ability of MSOT imaging data to correlate with clinical findings identified via pathology or radiology. The device will be used to obtain images of the areas of inflammation in the above patients for investigational use only, to compare to clinical pathology and patient's medical record. Patients will go through standard care procedures prior to imaging. Medically established diagnostic procedures will be used to detect areas of inflammation associated with GVHD, Crohn's, or colitis. Images using the MSOT device will be obtained through intact skin. A second MSOT scan will be performed for all patients 4 weeks post treatment. The temperature of the patient's skin will also be measured prior to and after MSOT imaging. MSOT imaging will be for research only and no treatment decisions will be based on the MSOT images obtained.

Eligibility Criteria
Inclusion Criteria
- •Patients documented clinical/pathologic 1) acute or chronic colon or skin GVHD, 2) Crohn's disease, or 3) colitis
- •Have acceptable hematologic status \[total hemoglobin (tHb) ≥ 7.0 mg/dL\]
- •Patients ≥ 18 yrs of age
- •Willing to comply with study procedures and be available for the duration of the study
- •Patient has ability to understand and the willingness to provide a signed and dated IRB-approved informed consent document.
Exclusion Criteria
- •Patients with a tattoo over the area of inflammation
- •Pregnant patients are not eligible for this trial. Eligible patients (if applicable) will be required to document the date of the first day of their last menstrual cycle, and provide a negative pregnancy test if sexually active and of childbearing potential
- •Patients who are breastfeeding
- •Any open wound (skin ulcerations or infections) at or near the site of imaging that would preclude MSOT imaging.
- •Any febrile illness that precludes or delays participation preoperatively
Arms & Interventions
Imaging of Inflammatory region
Inflammatory regions of patients scheduled for standard of care clinical visits will be imaged using the MSOT device before and after 4 weeks of treatment. The temperature of their skin prior to and after MSOT imaging will also be measured.
Intervention: MSOT Device

Intervention: Temperature Measurement
Outcomes
Primary Outcomes
Adverse Events due to MSOT imaging 4 weeks after treatment.
Time Frame: 5 minutes for an MSOT image (up to 48 hours post-image)
Proportion of patients that experience adverse events as characterized by CTCAE v5.0 resulting from MSOT imaging.A second MSOT image will be taken after 4 weeks of treatment.The MSOT image will take up to 5 minutes and adverse events at the time of the image (1-5 minutes) and for up to 48 hours post the image will be reported.
Measurement of skin temperature after first MSOT image post enrollment.
Time Frame: 1-2 minutes after the MSOT image.
Proportion of patients with skin temperatures measured post- MSOT imaging with a touch thermometer as part of the safety evaluation of the MSOT device. MSOT imaging will be performed after patient enrollment on the study. A temperature measurement will be recorded by placing the touch thermometer onto the skin until a temperature appears (about 30 seconds) after the MSOT image is obtained.
Measurement of skin temperature after second MSOT image post-treatment.
Time Frame: 1-2 minutes after the MSOT image.
Proportion of patients with skin temperatures measured post- MSOT imaging with a touch thermometer as part of the safety evaluation of the MSOT device. MSOT imaging will be performed 4 weeks after treatment for the inflammatory disease. A temperature measurement will be recorded by placing the touch thermometer onto the skin until a temperature appears (about 30 seconds) after the MSOT image is obtained.
Adverse Events due to MSOT imaging post enrollment.
Time Frame: 5 minutes for an MSOT image (up to 48 hours post-image)
Proportion of patients that experience adverse events as characterized by CTCAE v5.0 resulting from MSOT imaging. The first MSOT image will be taken post-enrollment on the study. The MSOT image will take up to 5 minutes and adverse events at the time of the image (1-5 minutes) and for up to 48 hours post the image will be reported.
Measurement of skin temperature before second MSOT image post-treatment.
Time Frame: 1-2 minutes before the MSOT image.
Proportion of patients with skin temperatures measured pre- MSOT imaging with a touch thermometer as part of the safety evaluation of the MSOT device. MSOT imaging will be performed 4 weeks after treatment for the inflammatory disease. A temperature measurement will be recorded by placing the touch thermometer onto the skin until a temperature appears (about 30 seconds) before the MSOT image is obtained.
Measurement of skin temperature before first MSOT image post enrollment.
Time Frame: 1-2 minutes before the MSOT image.
Proportion of patients with skin temperatures measured pre-MSOT imaging with a touch thermometer as part of the safety evaluation of the MSOT device. MSOT imaging will be performed after patient enrollment on the study. A temperature measurement will be recorded by placing the touch thermometer onto the skin until a temperature appears (about 30 seconds) before the MSOT image is obtained.
