  Purpose

The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Magnevist (the study drug) used for MRI of the renal arteries. The results will be compared to the results of MRI taken without Magnevist and with the results of your X-ray angiography.


Condition Intervention Phase
Renal Artery Stenosis
Drug: Gadopentetate dimeglumine (Magnevist)
Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: Multicenter, Open-label Study of the Safety (Open-label) and Efficacy (Open-label and Blinded Reader) of a Single Administration of Approximately 0.1 mmol/kg of Magnevist® Injection-enhanced Magnetic Resonance Arteriography (MRA) and 2-dimensional-time-of-flight (2D-TOF) MRA in Patients With Known or Suspected Renal Artery Disease Undergoing MRA of the Renal Arteries With Intra-arterial Digital Subtraction Arteriography (i.a. DSA) as the Standard of Reference

Primary Outcome Measures:
  • Accuracy, sensitivity and specificity based on quantitative assessment of stenosis [ Time Frame: Image creation after injection - evaluation at blind read ]

Secondary Outcome Measures:
  • Diagnostic confidence [ Time Frame: At blinded and/or open label read of images ]
  • Accuracy, sensitivity, and specificity based on visual assessment of stenosis assesses [ Time Frame: At blinded and/or open label read of images ]
  • Difference in degree of stenosis [ Time Frame: At blinded and/or open label read of images ]
  • Other diagnostic findings [ Time Frame: At blinded and/or open label read of images ]
  • Localisation matching of maximum stenosis [ Time Frame: At blinded and/or open label read of images ]
  • Image quality [ Time Frame: At blinded and/or open label read of images ]
  • Image evaluability and presence of artifacts [ Time Frame: At blinded and/or open label read of images ]
  • Proportions of correctly categorised arteries with regard to maximum stenosis [ Time Frame: At blinded and/or open label read of images ]
  • Number of evaluable arteries [ Time Frame: At blinded and/or open label read of images ]
  • Patient management [ Time Frame: From baseline to 24 hours follow-up ]
  • Safety [ Time Frame: From baseline to 24 hours follow-up ]
