What is this trial about?
A plain-language summary of the goals, design and what participants do
This study focuses on testing a new imaging method in patients with various types of cancer, including breast cancer, neuroendocrine neoplasms, lymphomas, and sarcomas. The research combines two different imaging techniques: Magnetic Resonance Spectroscopy using a substance called hyperpolarized [1-13C]pyruvate and PET scanning using Fluor-18-FDG (a radioactive form of glucose).
The purpose of this study is to determine whether it is possible to perform both imaging methods at the same time to better understand how tumors use energy. During the study, participants will receive two different injectable substances: hyperpolarized [1-13C]pyruvate and Fluor-18-FDG. Both substances will be given through an intravenous injection, and then special images will be taken using a combined PET/MR scanner.
This research will help doctors better understand how tumors process different nutrients and may lead to improved ways of detecting and monitoring cancer. The imaging procedure will be performed once for each participant, and the total dose of each substance has been carefully calculated to ensure safety.
The research process
The trial runs in 5 steps – from screening to follow-up. Each step says what happens and what the team monitors.
Who can join the trial?
8 criteria
- Age: Must be an adult (18 years or older)
- Gender: Both men and women can participate
- Must have a confirmed diagnosis of one of these cancers:
- Breast cancer
- Neuroendocrine neoplasm (tumors that begin in specialized cells that produce hormones)
- Lymphoma (cancer that begins in infection-fighting cells of the immune system)
- Sarcoma (cancer that starts in tissues like bone or muscle)
- The tumor must be at least 1.5 centimeters in size (about the size of a grape)
- Must not be part of any vulnerable population groups (such as persons unable to give consent)
Who cannot join the trial?
12 criteria
- Age under 18 years or over 65 years old
- Patients who are unable to lie still in the PET/MR scanner (a combined imaging machine) for up to 60 minutes
- Patients with claustrophobia (fear of confined spaces)
- Patients with metal implants or devices not compatible with MRI (magnetic resonance imaging)
- Pregnant or breastfeeding women
- Patients with severe kidney dysfunction, as this may affect the processing of imaging substances
- Patients with known allergies to the imaging substances used in the study
- Patients who have received other experimental drugs within 30 days before the study
- Patients who cannot provide informed consent
- Patients with uncontrolled medical conditions that could interfere with the imaging procedures
- Patients weighing more than 180 kg (397 lbs) due to scanner limitations
- Patients with blood glucose levels above 200 mg/dL at the time of imaging

Investigated drugs
What is already known about the treatment
Hyperpolarized [1-13C]Pyruvate
A diagnostic imaging agent administered intravenously during magnetic resonance spectroscopy (MRS) procedures for cancer detection and monitoring. This compound is a specially prepared form of pyruvate where the carbon-13 atoms are hyperpolarized to enhance imaging signals, allowing real-time visualization of cellular metabolism in cancer tissues. The substance is currently used in clinical research to study metabolic changes in various types of cancer, including breast cancer, neuroendocrine tumors, lymphomas, and sarcomas, by tracking how quickly cancer cells convert pyruvate to lactate.
18F-FDG (18-Fluoro-deoxy-glucose)
A radioactive form of glucose used in Positron Emission Tomography (PET) imaging, administered intravenously to detect and monitor various types of cancer. This tracer accumulates in cells with high glucose metabolism, particularly cancer cells, making them visible during PET scanning. It is widely established in clinical practice as a standard diagnostic tool for cancer imaging, helping physicians to detect tumors, assess treatment response, and monitor disease progression in various cancer types including breast cancer, lymphomas, and sarcomas.
Investigated diseases
Breast cancer
A disease that begins when cells in the breast tissue start to grow abnormally and divide more rapidly than healthy cells. These cells typically form a mass or lump that can be felt in the breast tissue. The cancer can develop in different parts of the breast, including the ducts that carry milk, the glands that produce milk, or other breast tissues.
Neuroendocrine neoplasms
A group of tumors that develop from specialized cells called neuroendocrine cells, which have traits of both nerve cells and hormone-producing cells. These tumors can form in various parts of the body and may grow slowly or quickly. The cells can produce various hormones that affect body functions.
Lymphomas
A group of blood cancers that develop in the lymphatic system, which is part of the body's immune system. These cancers begin in lymphocytes, which are white blood cells that help fight infection. The abnormal lymphocytes collect in lymph nodes and other tissues, forming tumors.
Sarcomas
A diverse group of cancers that develop in the body's connective tissues, including bone, muscle, fat, blood vessels, and soft tissues. Unlike most other cancers that develop in organs, sarcomas can occur anywhere in the body where these connective tissues are found. These tumors develop from cells in these supportive tissues that begin to grow abnormally.
