E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the efficacy of 0.1 mmol/kg OMNISCAN for 3 dimensional contrast-enhanced magnetic resonance angiography (3D CE MRA) compared to 2 dimensional time-of-flight (2D TOF) MRA in the identification of the presence or absence of main haemodynamically relevant stenoses (ie, ≥50% or occlusion) within turbulent flow arteries of the aorto-iliac region. Intra-arterial digital subtraction angiography (IA DSA) will be used as the standard of truth.
|
|
E.2.2 | Secondary objectives of the trial |
•To determine the efficacy of 0.1 mmol/kg OMNISCAN for 3D CE MRA compared to 2D TOF MRA in the identification of the presence or absence of the main haemodynamically relevant stenosis (ie, ≥50% or occlusion) on a segment to segment level within any of the 7 aorto-iliac arterial segments. IA DSA will be used as the standard of truth. •To evaluate the impact of 3D CE MRA findings compared to those of 2D TOF MRA and IA DSA on overall clinical utility on the basis of the consensus decision of a vascular surgeon and a radiologist as to: the occlusion or stenosis requiring the most radical treatment and the recommendation of the most appropriate revascularisation strategy for the lesion (ie, endovascular intervention combined with vascular surgery, vascular reconstructive surgery, endovascular intervention, no revascularisation possible, no revascularisation necessary).

E.3 | Principal inclusion criteria |
(1)The subject has suspected or proven chronic PAOD predominantly located in the aorto-iliac region of Fontaine Stages IIb to IV (ie, Rutherford Stages I3-III), or presents with an ankle brachial pressure index of <0.70 (measured no more than 3 months prior to screening). (2)The subject has been referred to IA DSA for determination of subject management (no more than 1 month prior to inclusion). (3)The subject has had no intervention or change of symptoms within the region of interest (ROI) between 3D CE MRA and IA DSA. (4)The subject is 18 years or older. (5)The subject is conscious and able to comply with study procedures. (6)Written and dated (ie, date and time) informed consent is obtained. (7)If the subject is a woman of childbearing potential, the results of a serum or urine human chorionic gonadotropin (β-HCG) pregnancy test, done at screening within 24 hours before dosing (with the result known before investigational product administration), must be negative. Only those women who are surgically sterile (have had a documented bilateral oophorectomy and/or documented hysterectomy) or post-menopausal (cessation of menses for more than for more than 1 year) will be allowed to enrol in the study without a pregnancy test at screening. |
|
E.4 | Principal exclusion criteria |
(1)The subject has a known hypersensitivity to either conventional X-ray or gadolinium-based MR contrast media including, but not restricted to, the investigational product. (2)The subject is lactating. (3)The subject is pregnant as defined by a serum or urine β-HCG pregnancy test obtained within 24 hours before administration of the investigational product. (4)The subject received or is scheduled to receive MRI contrast medium within 24 hours prior to or less than 24 hours after administration of the investigational product. (5)The subject received or is scheduled to receive X-ray contrast medium within 24 hours prior to or less than 24 hours after administration of the investigational product. (6)The subject received an investigational product other than OMNISCAN within 30 days prior to OMNISCAN administration or will receive an investigational product within the follow-up period proposed for this study. (7)The subject presents any clinically active, serious, life-threatening disease with a life expectancy of less than 6 months. (8)The subject has a serum creatinine value of >3.5 mg/dL (309.4 µmol/L). (9)The subject has previously been included in this study. (10)The subject has a contra-indication for MRI according to accepted clinical guidelines. (11) The subject has metal implants and/or stents in the aorto-iliac region and/or hip replacement.

E.5 End points |
E.5.1 | Primary end point(s) |
To determine the efficacy of 0.1 mmol/kg OMNISCAN for 3 dimensional contrast-enhanced magnetic resonance angiography (3D CE MRA) compared to 2 dimensional time-of-flight (2D TOF) MRA in the identification of the presence or absence of main haemodynamically relevant stenoses (ie, ≥50% or occlusion) within turbulent flow arteries of the aorto-iliac region. Intra-arterial digital subtraction angiography (IA DSA) will be used as the standard of truth.
Co-primary endpoints The following primary efficacy endpoints will be evaluated simultaneously for each MRA reader: (1)Difference in sensitivity between 3D CE MRA and 2D TOF MRA in the identification of the main haemodynamically relevant stenosis (ie, ≥50% or occlusion) on a subject level across the 7 aorto iliac arterial segments with IA DSA as the standard of truth. The main stenosis is defined as the stenosis with the highest grade (ie, percentage decrease in vessel diameter) in one of the 7 vessel segments as determined by the IA DSA blinded image evaluation (BIE). (2)Difference in specificity between 3D CE MRA and 2D TOF MRA in the identification of a haemodynamically relevant stenosis (ie, ≥50% or occlusion) based on all of the 7 aorto-iliac arterial segments combined with IA DSA as the standard of truth. All vessel segments across all subjects which are determined to have no haemodynamically relevant stenosis by the IA DSA BIE will be considered for the calculation of specificity. The results of 3 independent blinded MRA readers in each subject will be compared separately to the IA DSA findings (read by 2 blinded DSA readers independently - in case of a mismatch between the 2 readers, the readers will be brought together, evaluate the images together and reach consensus).
