EXCLUSION CRITERIA:
GENERAL EXCLUSION CRITERIA:
- screening labs demonstrating any value for hepatic or renal function levels out of the range of normal, to include AST, ALT, bilirubin, alkaline phosphatase, creatinine, eGFR
- evidence of polycythemia vera with hemoglobin levels more than 1 standard deviation above the NIH laboratory s normal level
- iron overload syndromes, including hemochromatosis, or subjects with evidence of iron overload with a baseline ferritin level greater than 370 ng/ml and percent saturation of transferrin level greater than 40%.
- previous or current alcohol and/or substance abuse per medical history or medical records
- medical contraindications for MRI (e.g., any non-organic implant or other device such as a cardiac pacemaker or infusion pump or other metallic implants, objects, or body piercings that are not MRI-compatible or cannot be removed)
- psychological contraindications for MRI (e.g., claustrophobia), to be assessed at the time the medical history is collected
- pregnancy or current breastfeeding
- reported history of clinically significant impaired hearing, because people with impaired hearing are at increased risk of sound-induced damage from the MRI scanner
- known allergy to dextran or drugs containing iron salts or any previous history of severe allergic reactions, anaphylaxis, to any drug
- clinically significant medical or neurological disorders that, in the judgment of the investigators might expose the patient to undue risk of harm confound study outcomes or prevent the participant from completing the study; examples of such conditions include but are not limited to diagnosis of certain types of cancer, cardiopulmonary conditions such as congestive heart failure, or uncontrolled hypertension

5. Study Description
Brief Summary
Background:
- Contrast agents help things show up better on magnetic resonance imaging (MRI) scans. Researchers want to see if the drug ferumoxytol is a good contrast agent. They want to determine that it does not cause prolonged MRI changes in the brain and to see if it helps identify inflammation in multiple sclerosis
Objective:
- To learn how ferumoxytol can be used to image inflammation in multiple sclerosis (MS).
Eligibility:
Adults ages 18 70 who have MS.
Healthy volunteers ages 18 70.
Design:
Participants will have 5 clinic visits over 6 months.
Participants will be screened with a medical history, neurological exam, and blood draw. Full clinical measures will be obtained.
Participants will have a 7 tesla brain MRI scan that may include gadolinium contrast agent. The MRI is a metal cylinder in a strong magnetic field. The participant will lie on a table that can slide in and out of the cylinder.
During visit 2, ferumoxytol with be given through a catheter (a thin plastic tube) that is inserted with a needle into a vessel in the arm.
<TAB>- Participants will then have a 7 tesla MRI scan of the brain..
At each of the next 3 clinic visits, participants will have a 7 tesla brain MRI and have blood drawn. The MRIs may include gadolinium.
Participants may have a full neurologic exam at these visits. At the final visit, full clinical measures will be obtained.
Participants may have more MRI scans if a 6-month MRI shows ferumoxytol still in the brain.
Detailed Description
Objective
The goals of this pilot study are to (1) demonstrate the safety of ferumoxytol, a United States Food and Drug Administration (FDA) approved drug used in the treatment of iron deficiency anemia, as a contrast agent for brain magnetic resonance imaging (MRI), as determined by a lack of long-term signal change in healthy volunteers (HV) and people with multiple sclerosis (MS); (2) determine if ferumoxytol enhancement can be detected in MS lesions on 7-tesla (T) MRI; and (3) examine the spatial and temporal enhancement patterns of ferumoxytol compared to patterns seen with gradient-echo imaging and gadolinium contrast in MS lesions.
Study population
Up to 10 HVs and up to 10 participants with MS will be recruited for this study.
Design
Participants will undergo a series of brain MRIs on a 7 T scanner. MRI will be before (baseline) and 0-8 hours, 24-96 hours, 1 month, and 6 months following ferumoxytol administration.
Outcome measures
The primary outcome measure is change in gradient-echo T2-weighted signal (derived from an MR sequence sensitive to paramagnetic agents such as iron) in the globus pallidus, a known brain iron reservoir, 6 months following ferumoxytol administration. Thus, we will determine if ferumoxytol induces long-lasting brain signal intensity changes in HV and MS. Secondary outcome measures are: (1) the number, location, and qualitative morphology of ferumoxytol, gradient-echo phase, and gadolinium-enhanced MS lesions and how these lesions change over time; and (2) quantitative estimates of change in iron concentration by determining R2 (= 1/T2) relaxation rate within MS lesions, normal appearing white matter, normal appearing gray matter, and other iron-rich regions within the brain before and after ferumoxytol injection.
