Brief Summary
The trial aimed at evaluating the efficacy and the safety of gadopiclenol for body Magnetic resonance Imaging (MRI)
Brief Title
Efficacy and Safety of Gadopiclenol for Body Magnetic Resonance Imaging (MRI)
Detailed Description
The purpose of this trial was to evaluate a new gadolinium-based contrast agent (GBCA) gadopiclenol in terms of lesion visualization in patients referred for contrast-enhanced MRI of body regions.
This is a prospective, international, multi-center, randomized, double-blind, controlled and cross-over trial.
This trial was conducted in 33 centers worldwide. During the course of the trial, two MRIs were obtained from each patient: one with gadopiclenol and one with gadobutrol. MRI evaluations were assessed by independent off-site blinded readers.

Eligibility Criteria
Inclusion Criteria:
* Patient presenting with known or suspected enhancing abnormality(ies) and/or lesion(s) in at least one body region based on a previous imaging procedure performed within 12 months prior to ICF signature. US patients are restricted to the breast in compliance with local approved indications of gadobutrol.
Exclusion Criteria:
* Patient presenting with acute or chronic renal insufficiency, defined as an estimated Glomerular Filtration Rate (eGFR) \< 30 mL/min/1.73 m² assessed within 1 day prior to each contrast agent administration.
* Patient presenting with known or suspected enhancing abnormality(ies) and/or lesion(s) in at least one body region based on a previous imaging procedure performed within 12 months prior to ICF signature. US patients are restricted to the breast in compliance with local approved indications of gadobutrol.

Primary Outcomes
Outcome Description
The lesion visualization at patient level was based on 3 co-primary criteria on marching lesions: border delineation, internal morphology and degree of contrast enhancement, assessed on the images acquired during the MRI performed with gadopiclenol by 3 independent readers. The independent blinded reader recorded each of the 3 co-primary criteria for up to 3 most representative lesions, using a 4-point scale (1 = poor \[internal morphology\] or none \[border delineation, contrast enhancement\], 2 = moderate, 3 = good, 4 = excellent). The mean of scores for each patient and for each co-criterion was calculated as follows: Mean of scores = score of lesion 1 + score of lesion 2 (if any) + score of lesion 3 (if any) divided by the number of lesions, ranged from 1 to 4. The difference in mean scores on matching lesions between Paired \[unenhanced and contrast-enhanced\] images and Pre-contrast \[unenhanced\] images was calculated for each of the 3 co-primary criteria and for each reader.
Outcome Measure
Lesion Visualization Comparing Gadopiclenol-enhanced MRI to Unenhanced MRI
Outcome Time Frame
At first MRI examination (gadopiclenol-enhanced MRI) for patients of Arm 1. At second MRI examination (gadopiclenol-enhanced MRI) for patients of Arm 2, performed 2-14 days after gadobutrol-enhanced MRI.
Secondary Outcomes
Outcome Description
The lesion visualization (per patient) was based on 3 co-primary criteria: border delineation, internal morphology and degree of contrast enhancement, assessed on the images performed with gadopiclenol and images performed with gadobutrol by 3 independent readers. The independent blinded reader recorded each of the 3 co-primary criteria for up to 3 most representative lesions, using a 4-point scale (1 = poor \[internal morphology\] or none \[border delineation, contrast enhancement\], 2 = moderate, 3 = good, 4 = excellent). The mean of scores for each patient and for each of the 3 lesion visualization co-criteria was calculated as follows: Mean of scores = score of lesion 1 + score of lesion 2 (if any) + score of lesion 3 (if any) divided by the number of lesions, ranged from 1 to 4. The difference in mean scores on matching lesions between gadopiclenol scores mean and gadobutrol scores mean was calculated for each of the 3 co-primary criteria and for each reader.
Outcome Time Frame
At each of two MRI examinations with an interval of 2-14 days between two MRI examinations
