Efficacy and Safety of Gadopiclenol for Body Magnetic Resonance Imaging (MRI)

Lesion Visualization Comparing Gadopiclenol-enhanced MRI to Unenhanced MRI

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.

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.
