Trial Outcomes & Findings for Efficacy and Safety Study to Evaluate Gadavist (Gadobutrol) as Contrast Agent in Magnetic Resonance Imaging (MRI) of Vascular Diseases in Chinese Patients (NCT NCT00395733)
NCT ID: NCT00395733
Last Updated: 2013-12-18
Results Overview
Each arterial segment visualized in magnetic resonance angiography (MRA) enhanced by Gadavist and Magnevist was characterized by the on-site investigators and by three independent blinded readers (reader 1, 2 and 3) according to a five-point scale (none/not assessable, poor, moderate, good, excellent), which takes into consideration intravascular contrast quality as well as vessel border delineation. The number of vessel segments with adequate diagnostic quality, i.e. good or excellent scores, was determined for each MRA image.

Participant Flow
Participants were recruited at specialized study centers if they satisfied the inclusion and exclusion criteria. All had known or suspected stenosis of arterial vessels in different vascular body regions with an indication for contrast-enhanced magnetic resonance angiography for diagnosis and further treatment.
Of 87 screened participants, 4 were not randomized (2 due to withdrawal of consent, 1 due to entering another clinical study and 1 was lost to follow-up). Thus, 83 participants were randomized to either the sequence Gadobutrol/Gadopentate dimeglumine (41 participants) or Gadopentate dimeglumine/Gadobutrol (42 participants).

PRIMARY outcome
Timeframe: 20-30 seconds after injectionPopulation: Per Protocol Set (PPS): All participants who have received contrast injection and are not invalid cases. Note: The contrast enhanced MR image from one participant was lost after assessment by the investigator, i.e. the PPS analysis for the blinded readers is based on the images of 66 participants only.
Each arterial segment visualized in magnetic resonance angiography (MRA) enhanced by Gadavist and Magnevist was characterized by the on-site investigators and by three independent blinded readers (reader 1, 2 and 3) according to a five-point scale (none/not assessable, poor, moderate, good, excellent), which takes into consideration intravascular contrast quality as well as vessel border delineation. The number of vessel segments with adequate diagnostic quality, i.e. good or excellent scores, was determined for each MRA image.
