Renal artery obstruction

Gadobutrol enhanced MRA of the renal arteries

Trial purpose

Subjects referred for a routine CTA (computed tomography angiography) or MRA (magnetic resonance angiography) will be invited to participate in the study and subjects will be involved in the study for between 2 and 12 days. Two to three visits to the study doctor will be required.
This study will compare the diagnostic results of Gadobutrol enhanced MRA images with MRA images taken without contrast agent using images from a CTA as the standard of reference, which may have been performed up to 60 days prior to enrolment. If a CTA has not been performed in this prior time period, a CTA is required for the study.
MRA and CTA images will be collected for an independent review (blinded read).

     -- Referred for evaluation of the renal arteries for clinically significant stenosis
     -- Follow-up for a metallic stent in a renal artery
     -- Prior imaging study (CTA) showing ≥ 50% renal artery stenosis (within 60 days prior to consent)
    - Willingness to undergo the routine Contrast Enhanced Magnetic Resonance Angiography (CE MRA) examinations with gadobutrol.
    - Willingness and ability to follow directions and complete all study procedures specified in the protocol.
    - Females of childbearing potential only: Negative pregnancy test on the day of the MRA prior to administration of study drug.
    - Written informed consent (IC), including information about the provisions of the Health Insurance Portability and Accountability Act (HIPAA) as applicable.
  • - Pregnant or nursing (including pumping for storage and feeding)
    - Received any other investigational product or participation in any other clinical trial within 30 days before enrollment into this study
    - Previous enrolment into this study or into any other Bayer sponsored study using gadobutrol
    - Contraindication to the MRA examinations (e.g. inability to hold breath; severe arrhythmias; very low cardiac output, severe claustrophobia, defibrillators or other metallic devices not approved for MRI)
    - Contraindication to the use of Gd-containing contrast agents (including subjects with suspicion for or known to have Nefrogenic Systemic Fibrosis (NSF)

    - Estimated glomerular filtration rate (eGFR) value < 30 ml/min/1.73 m2 derived from a serum creatinine result within 2 weeks before the gadobutrol injection. Any subject on hemodialysis or peritoneal dialysis is excluded from participation. Use the value obtained prior to and closest to the time of the MRA, if there are multiple creatinine values. (Do not use the core lab value if not available prior to the MRA.)

  • Additional imaging studies recommended (example: non contrast MRA, contrast enhanced MRA, computed tomography angiography, Ultrasound, Nuclear medicine study)
    What additional imaging studies would be necessary is a measure of 1) what test provides a definitive diagnosis for treatment decisions and 2) is a direct measure of additional cost a health system would incur for additional imaging studies to reach a definitive diagnosis. This is critical to determining the total cost of imaging for a patient diagnosis in any health system reimbursement structure. Therefore the social/societal cost for not providing a definitive diagnosis with a single imaging study can be determined for health policy and reimbursement decisions.
