E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess in at risk patients (patients with at least moderate renal insufficiency) the frequency of contrast-induced nephropathy after Dotarem-enhanced MRI, in comparison with the frequency of nephropathy after unenhanced MRI and to observe an equivalence between both procedures regarding these frequencies. |
|
E.2.2 | Secondary objectives of the trial |
-To confirm the clinical and biological safety of DOTAREM® by assessing vital signs, laboratory parameters and adverse events through a 72±24 hours post treatment (DOTAREM®) or post procedure follow-up period. -To assess the serum creatinine level fluctuation in term of mean difference between baseline and 72 ±24 hours after examination. -To evaluate the estimated Glomerular Filtration Rate fluctuation in term of percentage and mean difference between baseline and 72 ±24 hours after examination. Estimated GFR will be assessed using the MDRD study equation. -If possible, to assess the potential influence of hydration protocol and/or prophylactic treatment on the renal function In case of rise in Serum creatinine level at 72±24 hours of at least 25% or 0.5mg/dl (44.2µmol/l), to observe the percentage of patients returned at baseline level 14 days after the imaging procedure.

E.3 | Principal inclusion criteria |
·Male or female, aged ≥ 18 years; Female of childbearing potential must have effective contraception (contraceptive pill or Intra-Uterine Device), or be surgically sterilized, or post-menopausal (minimum 12 months of amenorrhea) or must have a documented negative urine or blood pregnancy test at screening; ·Patient presenting with a known stable stage III to stage IV renal insufficiency according to the K/DOQI definition, i.e., 15 < estimated GFR < 60 ml/min/1.73m² according to MDRD formula; stability will be demonstrated with 2 consecutive values (within 15% of each other): a previous value obtained at least one week in advance (not more than 6 months in advance) and the most recent one obtained prior to the study procedure, on the same day or on the day before; ·Patient scheduled to undergo a contrast enhanced MRI or unenhanced MRI examination to specify a diagnosis; .Patient receiving angiotensin-converting enzyme inhibitors, angiotensine II receptor blockers ("sartans"), diuretics and fibrates, must be receiving these drug(s) at stable dosage(s) for at least 2 weeks; in addition the dosage(s) should not be modified for the whole study duration (i.e., until 72 hours +/-24 hrs or 14 days after the imaging procedure); ·Patient able to understand and having provided written informed consent to participate in the trial; .Patient for whom blood samples can be obtained on the day of the imaging procedure or on the day before and 72 hours (+ or - 24h) after the examination.

E.4 | Principal exclusion criteria |
·Patient with a contraindication to MRI (e.g., pacemaker, aneurysm clip, severe claustrophobia, metallic joint replacement or others according to the imaging laboratory's standard practice); ·Patient who has a diagnosis of a hemodynamic instability (cardiogenic shock – persistent systolic pressure < 90 requiring inotropic support) or acute myocardial infraction within 15 days prior the inclusion; ·Patient who needs hemodialysis; ·Patient with known allergy to gadolinium chelates (only applicable for patient undergoing Dotarem-enhanced MRI); Patients receiving anticalcineurine drugs, such as ciclosporine, unless the patient has been having a stable (variation ≤15%) creatinine level for at least 6 months, as demonstrated with available creatinine values, and has been receiving the drug at stable dosage for at least 6 months; this dosage should not be modified for the whole study duration (i.e., until 72 hours +/-24 hrs or 14 days after the imaging procedure); ·Patient receiving any other medications known to be nephrotoxic or to cause increases in serum creatinine level (e.g., selective inhibitors of cyclo-oxygenase 2, anti-vascular Endothelium Growth Factors, vancomycine, aciclovir, aminoglycosides, amphotericin B, polymixin, platinium complexes, non-steroidal anti-inflammatory treatment except acetyl salicylic acid, etc.) within 2 weeks before first blood sample and for the whole study duration (i.e., until 72 hours +/-24 hrs or 14 days after the imaging procedure); ·Patients planned to either undergo surgery or receive chemotherapy within 72 hours post-procedure (i.e: before the blood test 72 hours post-procedure); ·Patient having had an imaging procedure (MRI or CT imaging, with contrast medium or not ) within 7 days of entering this protocol; ·Patient with a planned imaging procedure (MRI or CT imaging, with contrast medium or not ) within 72 hours post-procedure; ·Patient with newly discovered unstable diabetes (i.e. <1month, glycaemia >= 2.5g);

E.5 End points |
E.5.1 | Primary end point(s) |
The evaluation of the renal tolerance after both procedures (MRI and DOTAREM®-MRI) will be done by assessing the serum creatinine levels from blood sampling taken within 24 hours before the imaging procedure and at 72 ±24 hours after the procedure.
This study will calculate in the two groups the percentage of patients presenting with a significant creatinine level increase according to the approach described hereafter.
Significant creatinine level increase (Nephrotoxicity) will be defined as a rise in serum creatinine level at 72±24 hours of at least 25% or 0.5mg/dl (=44.2µmol/l) compared to baseline.
