What You Need to Know Before You Apply

What is the purpose of this trial?

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.

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is MSOT Imaging safe for humans?

Optical imaging, including optoacoustic imaging like MSOT, is generally considered safe as it is noninvasive and does not use ionizing radiation. It has been successfully used in preclinical research and pilot clinical applications in humans. ^{1 2 3 4 5}

How does MSOT imaging differ from other treatments for inflammation?

MSOT imaging is unique because it is a noninvasive technique that uses light and sound to create detailed images of inflammation in the body, allowing for real-time monitoring without the need for contrast agents or invasive procedures. ^{6 7 8 9 10}

What data supports the effectiveness of the MSOT Device treatment for inflammation?

The research suggests that advanced imaging techniques, like those used in the MSOT Device, can improve the detection and monitoring of inflammation, which is crucial for effective treatment planning. These imaging methods can potentially identify inflammation early and assess the response to therapy, which is beneficial for managing inflammatory diseases. ^{1 11 12 13 14}

A new clinical test using a radioimaging agent can quickly predict how well patients with autoimmune/inflammatory diseases will respond to various therapies by measuring uptake in inflammatory macrophages.

In animal models of diseases like rheumatoid arthritis and inflammatory bowel disease, successful treatments showed a significant decrease in the radioimaging agent uptake, indicating effectiveness long before clinical symptoms improved, which could help avoid ineffective treatments and reduce costs.

In a study involving 14 rabbits, 93% developed steroid-associated osteonecrosis (ON) after receiving a low-dose lipopolysaccharide (LPS) injection followed by high-dose methylprednisolone (MPS), indicating a high incidence of ON under this experimental protocol.

The study revealed significant changes in blood parameters and imaging results, such as increased intravascular thrombus and larger extravascular marrow fat cells in ON rabbits, suggesting that both intra- and extravascular factors contribute to the development of steroid-associated ON.
