Study Details

Study Description

Brief Summary

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.

Condition or Disease Intervention/Treatment Phase
Phase 4

Detailed Description

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.

      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.

      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.

    Study Results

    Participant Flow

    Recruitment Details A total of 229 patients were recruited from September 2012 through November 2013 at 19 clinical trial sites. Off-site assessment of the images was performed between 21 January and 3 April 2014 by 3 board-certified neuroradiologists blinded as to which contrast agent was used, patient clinical information, and the results of other imaging studies.
    Pre-assignment Detail 229 patients were enrolled and signed informed consent. Each enrolled patient was randomized and dosed with at least one contrast agent.
