Trial Summary

What is the purpose of this trial?

This study is a postmarketing requirement jointly carried out by four NDA holders (Bayer AG, Bracco, GE Healthcare and Guerbet) and the CRO IQVIA. The study aims to create detailed images of the organs and tissue of the human body during x-ray, CT-scan or MRI investigations, doctors are using contrast media (a kind of dye) which can be given to patients by injection into a blood vessel or by mouth. In this study researchers want to find out whether so called gadolinium-based contrast agents (GBCAs) have an effect on body movement and mental skills when given to participants multiple times within 5 years. The study plans to enroll about 2076 participants suffering from a condition for which they are likely to have at least annually a MRI or another imaging examinations. Only adults up to 65 years will be considered to join this study. During the study duration of 5 years participants will receive annually a MRI or other imaging tests (such as CT-scan, x-ray) and will visit the study doctor at least 7 times for physical examinations, laboratory investigations and tests on body movement and mental skills.

Will I have to stop taking my current medications?

The trial requires that participants do not use medications affecting neuro-cognitive or motor function. If you are taking such medications, you may need to stop them to participate.

What data supports the effectiveness of the drug Gadobenate dimeglumine and similar gadolinium-based contrast agents on motor and cognitive functioning?

The study comparing gadodiamide injection and gadopentetate dimeglumine found that gadodiamide was a safe and effective contrast agent for imaging the central nervous system, with contrast enhancement observed in a significant number of patients with structural abnormalities. This suggests that gadolinium-based contrast agents can effectively enhance imaging, which may indirectly support their use in assessing conditions affecting motor and cognitive functions. ^{1 2 3 4 5}

Is gadolinium-based contrast media safe for humans?

Gadolinium-based contrast agents, like gadodiamide and gadobenate dimeglumine, have been studied for safety in humans. Some people experienced mild and temporary side effects, but these were not serious and did not require treatment. Overall, these agents are considered safe for use in medical imaging. ^{1 2 6 7 8}

How does the drug used in the Gadolinium-Based Contrast Media Effects on Motor and Cognitive Functioning trial differ from other treatments?

The trial focuses on the effects of gadolinium-based contrast media, which is unique because it is typically used in imaging tests like MRIs to enhance the visibility of internal structures, rather than as a direct treatment for cognitive or motor function. This contrasts with other treatments like galantamine or piribedil, which are specifically used to improve cognitive function or memory. ^{9 10 11 12 13}

Trial Overview The study is examining if repeated use of gadolinium-based contrast agents (GBCAs) during MRIs over five years affects motor skills and cognitive functions. It involves annual MRIs and tests on body movement/mental skills across four GBCA types versus unenhanced-MRI controls.

Participant Groups

Group I: No GBCA (Control arm) Experimental Treatment 4 Interventions

Adult participants who were never exposed to any gadolinium-based contrast agent and matching the population characteristics of the two GBCA arms. They will not receive any gadolinium-based contrast agent over the study course, but may undergo clinically indicated imaging (e.g. unenhanced magnetic resonance imaging (MRI), unenhanced or enhanced computed tomography, ultrasound and/or X-ray).

Group II: Macrocyclic GBCAs Experimental Treatment 7 Interventions

Adult participants, who were scheduled for repeated enhanced magnetic resonance imaging (MRI), receive a macrocyclic gadolinium-based contrast agent (GBCA, i.e. Gadavist/ Gadovist, Dotarem, Magnescope or ProHance) prior to MRI. Each participant will receive the same GBCA throughout the study.

Group III: Linear GBCAs Experimental Treatment 7 Interventions

Adult participants, who were scheduled for repeated enhanced magnetic resonance imaging (MRI), receive a linear gadoliniumbased contrast agent (GBCA, i.e. Eovist/ Primovist, MultiHance or Omniscan) prior to MRI. Each participant will receive the same GBCA throughout the study.

Findings from Research

In a study of 194,400 intravenous administrations of gadolinium-based contrast agents (GBCA), the overall rate of adverse reactions was low at 0.1%, with most reactions being mild.

Among the different GBCA types, gadofosveset trisodium had the highest reaction rate at 0.80%, while gadopentetate dimeglumine had the lowest at 0.09%, indicating variability in safety profiles among these agents.

Patients who received gadobenate dimeglumine after prior exposure to gadodiamide showed a significant increase in T1 signal intensity in the dentate nucleus compared to those without previous gadodiamide exposure, indicating potential gadolinium deposition effects.

The study suggests that prior administration of less stable gadolinium-based contrast agents (like gadodiamide) may enhance the effects of subsequent administrations of more stable agents (like gadobenate dimeglumine), although the exact mechanism and implications for safety require further investigation.

In a study of 32 patients with posttreatment glioma, gadobutrol (one-molar) and gadoterate meglumine (half-molar) showed no significant differences in key dynamic contrast-enhanced imaging parameters, indicating they can be used interchangeably.

However, gadobutrol demonstrated a significantly higher wash-in rate and a lower washout rate compared to gadoterate meglumine, suggesting slight differences in how these agents behave during imaging.

In a study of 211 patients comparing gadoxetic acid and gadoteric acid for liver MRI, gadoxetic acid resulted in significantly poorer image quality during the triple arterial phases, despite better pre-contrast images.

The overall image quality improved from the first to the third arterial phases for both contrast agents, suggesting that the third arterial phase images are the most reliable for diagnostic purposes.

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 study involving 3092 subjects across 79 clinical trials, gadobenate dimeglumine (MultiHance) was found to have a safety profile comparable to placebo and other contrast agents, with only 14% of adult subjects reporting adverse events.

MultiHance was well tolerated in special populations, including children and individuals with liver or kidney impairment, showing no significant increase in adverse events or negative effects on cardiac function.

Piribedil, at a dose of 10 mg/kg, significantly improved memory performance in aged mice, particularly in tasks assessing relational and declarative memory, while bromocriptine showed no such effects.

Both dopamine agonists enhanced memory in young adult rats, but only piribedil demonstrated lasting benefits against age-related memory impairments, suggesting its potential as a treatment for cognitive deficits in Parkinson's disease.

In a study of 515 elderly patients, piribedil, a dopamine agonist, significantly improved memory impairment, vertigo, and tinnitus, with 20% experiencing complete resolution and 72.6% showing improvement after one month of treatment.

The treatment was well tolerated, with a low incidence of side effects and high compliance among patients, indicating its acceptability as a therapeutic option for age-related dopamine decline.
