Efficacy and Safety of Gadopiclenol for Body Magnetic Resonance Imaging (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.

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.
