Trial Summary

What is the purpose of this trial?

If an abbreviated HBP protocol liver MR with gadobenate dimeglumine is shown clinically comparable to standard of care liver MR with gadoxetate disodium for detecting hepatic metastasis from colorectal cancer, its use will save time, cost, and patients' effort.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the drug for detecting liver metastases?

Research shows that combining gadoxetic acid and gadobenate dimeglumine in liver MRI can improve the detection of liver metastases by optimizing the contrast agent dose and timing. ^{1 2 3 4 5}

Is the contrast agent gadoxetate disodium safe for use in humans?

Gadoxetate disodium is generally safe and well tolerated for liver MRI, with 1.7% of patients experiencing mild adverse events like shortness of breath and nausea. Serious adverse events were rare, and no deaths occurred in the studies. ^{3 6 7 8 9}

How is the drug used in the clinical trial for detecting liver metastases different from other treatments?

The drug gadoxetate disodium (Eovist) is unique because it is a liver-specific contrast agent used in MRI that provides both dynamic imaging and liver-specific static imaging, which helps in detecting smaller liver lesions more effectively than other imaging methods. It is particularly useful for identifying liver metastases due to its high sensitivity and ability to enhance liver-to-lesion contrast. ^{1 3 10 11 12}

Treatment Details

Interventions

• Gadobenate dimeglumine
• Gadoxetate disodium

Trial Overview The study compares two MRI contrast agents: Gadoxetate disodium (standard care) versus Gadobenate dimeglumine (potential time and cost saver). The goal is to see if the latter can detect liver metastases from colorectal cancer as effectively as the former.

The subjects will be randomized into two groups. Both groups will undergo two complete protocol liver MRs for known or suspected CRC metastasis, one exam with gadoxetate disodium and the other exam with gadobenate dimeglumine, within an interval of 3-10 days, but in opposite order, determined randomly.

Group II: Gadobenate Dimeglumine exam first Active Control 2 Interventions

The subjects will be randomized into two groups. Both groups will undergo two complete protocol liver MRs for known or suspected CRC metastasis, one exam with gadoxetate disodium and the other exam with gadobenate dimeglumine, within an interval of 3-10 days, but in opposite order, determined randomly.

Findings from Research

The study demonstrated that using a combination of gadoxetic acid (GA) and gadobenate dimeglumine (GD) in liver MRI can create a 'plain-white-liver' effect, enhancing the visibility of liver structures and potentially improving the detection of metastases.

Optimal imaging conditions were identified, with the best contrast achieved 60-120 seconds after GD administration and using a lower dose of GA (0.025 mmol/kg), suggesting that this protocol could enhance sensitivity in detecting liver lesions in future patient studies.

In a study of 127 patients with liver nodules, gadobenate dimeglumine and gadoxetate disodium showed similar rates of arterial phase hyperenhancement, indicating both contrast agents are effective for this feature in liver imaging.

However, gadobenate dimeglumine was superior in visualizing dynamic phase washout and the capsule feature, suggesting it may provide better overall imaging for hepatocellular carcinoma detection.

In a study of 140 pediatric MRI cases using gadoxetate disodium, transient severe respiratory motion occurred in 7.84% of non-sedated patients, which is lower than the 5-22% reported in adult studies.

No cases of transient severe respiratory motion were observed in sedated patients, suggesting that sedation may effectively eliminate this issue during imaging.

Gadobenate dimeglumine (MultiHance) demonstrated significantly higher sensitivity for detecting intracranial metastases (93%-100%) compared to other MRI contrast agents, which had sensitivity rates of only 65%-73%.

The increased lesion-to-brain contrast with gadobenate dimeglumine (+43%) compared to comparator agents (+27%) suggests that its higher relaxivity contributes to its superior efficacy in identifying metastatic lesions.

In a study involving 12 patients at risk for hepatocellular carcinoma (HCC), gadoxetic acid showed higher sensitivity for HCC detection compared to gadopentetate dimeglumine for one of the observers, indicating it may be more effective in identifying liver tumors.

Both contrast agents provided similar image quality, but gadoxetic acid enhanced lesion conspicuity and liver-to-lesion contrast during the hepatobiliary phase, suggesting it may offer better visualization of HCC in clinical settings.

In a study involving 8194 patients across multiple countries, gadoxetate disodium was found to have a low adverse event rate of 1.7%, indicating it is generally safe for routine use in liver MRI.

The most common adverse events were mild, such as dyspnea and nausea, and importantly, no serious adverse events were related to the drug in the pediatric population, highlighting its safety profile.

A total of 424 risk signals related to adverse events (AEs) were identified from the FAERS database for four gadolinium-based contrast agents (GBCAs) over an 18-year period, highlighting significant safety concerns associated with these agents.

The study revealed that some adverse events linked to GBCAs were not included in their package inserts, indicating a need for further research to ensure patient safety and awareness of potential risks.

In a review of safety data from 12 clinical studies involving 1989 patients, gadoxetate disodium showed a high safety profile, with only 10.1% of patients reporting adverse events, and only 4.1% classified as related to the drug.

The most common related adverse events were nausea and headache, each occurring in 1.1% of patients, and the safety profile remained consistent across various patient subgroups, including those with liver cirrhosis or impaired function.

In a study of 10,595 patients undergoing MRI with gadolinium-based contrast agents, the overall incidence of acute adverse reactions was low at 0.45%, with no severe reactions reported.

Younger patients were found to be at a higher risk for experiencing acute adverse reactions, and gadoxetate disodium had a higher incidence of reactions (0.82%) compared to gadopentetate dimeglumine (0.43%), indicating that while all agents are generally safe, some may carry slightly more risk.

Gadoxetate acid (Gd-EOB-DTPA) is a safe and effective liver-specific contrast agent that enhances MRI imaging, improving the detection and characterization of hepatocellular carcinoma (HCC) compared to unenhanced MRI and other imaging methods.

The use of gadoxetate acid allows for better differentiation of early HCC from benign or premalignant nodules, which is crucial for determining appropriate management strategies and improving patient outcomes.

Gadoxetic acid-enhanced MRI is significantly more sensitive than contrast-enhanced CT for detecting liver metastases, especially for lesions smaller than 1 cm, making it a valuable diagnostic tool.

This imaging technique provides both dynamic and static liver-specific information, which can improve treatment planning for patients with liver metastasis.

Magnetic resonance imaging (MRI) is highly effective for diagnosing liver and bile duct issues in children, with noncontrast MRI showing good results due to the visibility of bile.

Using the hepatocyte-specific contrast agent gadoxetate disodium (Eovist) enhances MRI by providing better characterization of liver lesions through its partial excretion, although there are specific applications and limitations to consider in pediatric patients.
