E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate that 1.02 g courses of ferumoxytol (delivered as either an undiluted IV injection or diluted IV infusion of 510 mg each) are noninferior to 1.0 g courses of iron sucrose (delivered either as slow IV undiluted injections or IV diluted infusions of 100 mg each) in raising hemoglobin after each treatment period in hemodialysis-dependent CKD subjects with IDA over a one-year period |
|
E.2.2 | Secondary objectives of the trial |
Main Study:
To evaluate the safety of repeat doses of ferumoxytol compared to iron sucrose for the treatment of IDA over a one-year period in subjects with hemodialysis-dependent CKD |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Oxidative Stress Substudy:
The primary objective of the Oxidative Stress Substudy is to evaluate changes in blood biomarkers of oxidative stress/inflammation during the initial Treatment Period (TP) of the Main Study.
MRI Substudy (AMAG-FER-CKD-401-MRI):
The objectives of the MRI Substudy are to assess the potential for deposition of iron in cardiac, hepatic, and pancreatic tissues and changes in laboratory parameters over a two-year period
Primary Objective:
To assess change from Baseline in cardiac iron deposition as determined by cardiac magnetic resonance imaging (MRI) T2* approximately 6, 12, and 24 months following initial dosing (TP Day 1 in the Main Study)
Secondary Objectives:
To assess change from Baseline in hepatic and pancreatic iron deposition as determined by MRI T2* approximately 6, 12, and 24 months following initial dosing
To assess change from Baseline in ferritin levels, TSAT, liver function tests, thyroid function tests, blood glucose, and Hemoglobin A1c approximately 6, 12, and 24 months following initial dosing |

7. Any other clinically significant medical disease or psychiatric disease or condition (eg, active malignancy, uncontrolled hypertension, acute medical illness/infection, psychosis) or subject responsibility that, in the Investigator’s opinion, may interfere with the subject’s ability to give informed consent or adhere to the protocol, interfere with assessment of the study agent, or serve as a contraindication to the subject’s participation in the study
MRI Substudy:
Additional exclusion criteria for subjects in the MRI Substudy include:
1. Has any contraindication to MR imaging, or otherwise unable to undergo MRI (e.g., pacemaker, recent wound clips, severe claustrophobia, unable to lay flat for sufficient time to undergo imaging)
2. Baseline cardiac T2* value < 20 ms |
