21197 Efficacy and safety of gadoquatrane for Body MRI
Research type
Research Study
Full title
A multicenter, randomized, prospective double-blind, cross over Phase 3 study to evaluate the efficacy and safety of 0.04 mmol Gd/kg body weight of gadoquatrane for MRI in adults with known or suspected pathology of any body region (except CNS), compared to 0.1 mmol Gd/kg approved macrocyclic gadolinium-based contrast agents (GBCAs)

Research summary
Researchers are looking for a better way to help people with any known or suspected problems (except brain or spinal cord-related problems) scheduled for a “contrast-enhanced” Magnetic Resonance Imaging (MRI).
MRI is used by doctors to create detailed images of the inside of the body to identify health problems. Sometimes doctors need to inject a contrast agent into a patient’s vein to perform a “contrast-enhanced” MRI (CE-MRI). Such CE-MRI may help identify certain health problems or improve the evaluation.
The contrast agents commonly used in MRI are gadolinium-based contrast agents (GBCAs). GBCAs contain a “rare earth” element called gadolinium (Gd). Gadoquatrane is a new contrast agent under development with a lower amount of Gd needed per CE-MRI.
The main purpose of this study is to learn whether CE-MRI scans with gadoquatrane work as well as those with currently used GBCAs. The researchers will compare the ability to detect problems in body regions except central nervous system with gadoquatrane-MRI scans to currently used GBCA-MRI scans.
The participants will undergo 2 MRI scans, one with gadoquatrane and one with currently used GBCA. Both contrast agents will be injected into the vein.
Each participant will be in the study for between 6 and 42 days with up to 7 doctor visits.
At the start or during the study, the doctors and their study team will:
• take blood and urine samples
• do physical examinations
• check blood pressure and heart rate
• review the MRI scans obtained in the study and decide on the diagnosis
• ask the participants questions about how they are feeling and what adverse events they are having.
An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatments.REC name
