Hyperpolarized 13C-Pyruvate Imaging for Chemotherapy-Related Heart Damage
(HPCardiotox Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to detect early heart changes caused by certain cancer treatments before symptoms appear. Using a special imaging technique with a compound called hyperpolarized [1-13C]pyruvate, doctors seek to understand how these treatments affect the heart's energy production. The trial consists of two parts: one examines patients before and after they start treatment, and the other assesses patients who have already completed treatment. It is suitable for breast cancer patients about to start or who have completed cardiotoxic therapy, as well as healthy volunteers. As an Early Phase 1 trial, this research focuses on understanding how the imaging technique functions in people, offering participants a chance to contribute to groundbreaking advancements in heart health monitoring.
Do I have to stop taking my current medications for the trial?
The trial information does not specify if you need to stop taking your current medications. However, if you are on investigational agents that are not compatible with the study, you may need to stop those.
What prior data suggests that hyperpolarized 13C-pyruvate imaging is safe for detecting chemotherapy-related heart damage?
Research has shown that Hyperpolarized [1-13C]Pyruvate is generally safe for people in studies. The safety data indicates it is safe when used in appropriate amounts. Trials have reported no major side effects, suggesting that Hyperpolarized Pyruvate does not harm patients when used as intended for medical imaging.
It is important to note that this is an imaging tool, not a medicine. It helps doctors observe changes in the heart's energy use after chemotherapy. While the safety data is promising, further research is underway to confirm these results.12345Why are researchers excited about this trial?
Researchers are excited about using hyperpolarized [1-13C]pyruvate imaging for detecting chemotherapy-related heart damage because it offers a new way to visualize metabolic changes in the heart in real time. Unlike traditional methods that may rely on symptoms or changes in heart function to detect damage, this technique uses a special form of pyruvate, the hyperpolarized [1-13C]pyruvate, which enhances MRI images to provide clear insights into heart cell metabolism. This could potentially allow for earlier detection of heart damage, even before significant symptoms arise, enabling more timely interventions. This technique is particularly promising because it provides a non-invasive method to monitor heart health during and after chemotherapy, offering a proactive approach to cardiac care.
What evidence suggests that hyperpolarized 13C-pyruvate imaging is effective for detecting chemotherapy-related heart damage?
Research has shown that a special imaging technique using hyperpolarized pyruvate can detect early changes in heart metabolism caused by doxorubicin, a chemotherapy drug known to harm the heart. This trial will employ hyperpolarized 13C-pyruvate imaging to assess heart metabolism in two contexts: one group will undergo imaging before and immediately after cardiotoxic therapy, while another group will receive it after completing therapy and again 1 to 6 months later. Studies confirm that this imaging effectively measures heart metabolism and provides insights into potential damage. By identifying these changes early, doctors aim to understand and possibly prevent long-term heart problems in cancer survivors. This approach seeks to catch heart issues before they become serious.13678

Are You a Good Fit for This Trial?
This trial is for adults with breast cancer who haven't started or have already completed cardiotoxic therapy. They must be able to use contraception, not have diabetes, metal implants incompatible with MRI, or severe illnesses that could affect study participation. Pregnant women and those with certain blood disorders are excluded.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Hyperpolarized [1-13C]Pyruvate
Trial Overview
The study aims to detect early signs of heart damage from the chemotherapy drug doxorubicin by using a special type of imaging after injecting hyperpolarized 13C-pyruvate. It will look at changes in heart metabolism as indicators of potential harm from this and similar treatments.
