Global Diagnostic Preference Between the Two Exams [ Time Frame: Comparison of image sets obtained within 2 to 14 days ] [ Designated as safety issue: No ]
Assessed by 3 blinded readers for each of the 198 patients who had post-dose exams for both ProHance and Gadovist/Gadavist. Readers assessed whether images with ProHance were preferred or images with Gadovist/Gadavist were preferred, or whether images after both exams were considered equal.
Non-inferiority of each exam based on pre-dose and post dose images [ Time Frame: Up to 14 days ] [ Designated as safety issue: No ]
To show non-inferiority of a 0.1 mmol/kg dose of PROHANCE as compared to 0.1 mmol/kg dose of GADOVIST/GADAVIST, in terms of the by-subject global diagnostic preference between exams (i.e., based on predose + postdose image sets).

Comparison of Prohance® With Gadovist®/Gadavist™ in Magnetic Resonance Imaging (MRI) of the Brain
Phase IV, Double-blind, Multi-center, Randomized, Crossover Study to Compare 0.1 mmol/kg of Prohance® With 0.1 mmol/kg of Gadovist®/Gadavist™ in Magnetic Resonance Imaging (MRI) of the Brain (TRUTH)

This study aims at a direct comparison between ProHance (0.1 mmol/kg) and a validated comparator Gadovist/Gadavist (0.1 mmol/kg) in a crossover intra-individual design in subjects with brain tumors to confirm the identical overall technical and diagnostic performance of the two MR contrast agents.

Adult patients were given two MRI exams, one after injection of ProHance (0.1 mmol/kg) and one after injection of Gadovist/Gadavist (0.1 mmol/kg). The exams were performed with identical equipment and imaging parameters with the order of the two exams randomized and 2-14 days between the first and the second MRI exam. Image data was evaluated by 3 expert neuroradiologist blinded to the agent administered and patient clinical data.
