Inclusion Criteria for MS Patients:
- Must have a documented diagnosis of relapsing MS (McDonald 2010
Criteria [Polman 2011]) at study screening.
- for subjects with a previous history of treatment with BRACE-TA
he/she must have:
• Been on therapy for at least 6 months (unless experiencing highly
active disease; see #6 below)
• At least 9 T2-hyperintense lesions on a brain MRI scan, and
• Experienced =1 relapse while on therapy within the last 6 months
prior to study screening and either:
* =1 new T1-Gd+ lesion or =2 new T2 lesions on a brain MRI scan
performed =6 months prior to study screening
or
* =2 new T2 lesions on a brain MRI scan performed =6 months prior
to study screening, with comparison made to a T2
MRI scan performed up to 18 months before study screening.
- For subjects with highly active disease (defined by the criteria below),
regardless of whether they are disease-modifying therapy (DMT)-naïve
or had previous exposure to BRACE TA, he/she must have had:
• =2 disabling relapses in the 12 months prior to study screening and
either:
?* =1 new T1 Gd+ lesion on a brain MRI scan performed =6 months
prior to study screening
or
?* =2 new T2 lesions on a brain MRI scan performed =6 months prior to
study screening with comparison made to a T2
MRI scan performed up to 18 months before study screening
- Willing to take natalizumab or fingolimod as the only DMTs for the
duration of the study treatment period.
- Must have an EDSS score from 0 to 5.5 inclusive at study screening.
Inclusion Criteria for Healthy Volunteers:
- Subjects who are generally healthy as demonstrated by physical
examination and by medical history, with no history or evidence of major
illnesses, diseases, or disorders.
- Subjects of childbearing potential must practice effective contraception
and be willing and able to continue contraception for duration of the
study.
- No history of drug or alcohol abuse (as defined by the Investigator)
within 1 year prior to study screening.
- Willing and able to comply with scheduled visits and imaging services.

Exclusion Criteria for MS Patients:
- History of or positive test result at study screening for HIV
- History or positive test result at study screening for HCV antibody or current hepatitis B infection (defined as positive for HBsAg and/or HBcAb). Subjects with immunity to hepatitis B from either active vaccination (defined as negative HBsAg, positive HBsAb and negative
HBcAb) or from previous natural infection (defined as negative HBsAg, positive HBsAb immunoglobulin G, and positive HBcAb) are eligible to participate in the study
- Prior treatment with natalizumab or fingolimod

- History of or known active malignant disease, including solid tumors and hematologic malignancies (subjects with cutaneous basal and squamous cell carcinoma that has been completely excised and considered cured prior to study screening remain eligible)
- History of opportunistic infections (including PML) or any clinically significant cardiac, endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, neurologic (other than MS), dermatologic, psychiatric, and renal condition, or other major disease
- A clinically significant infectious illness (eg, pneumonia, septicemia) within the 1 mth prior to study screening
- History of drug or alcohol abuse within 1 yr prior to study screening
- Exposure to IVIg, monoclonal antibodies, cytokines, growth factors,
soluble receptors, other recombinant products, or fusion proteins within 1 yr prior to study screening
- History of immunosuppressant use (eg, mitoxantrone, azathioprine, methotrexate, cyclophosphamide, mycophenolate, cladribine, rituximab) in the last 12 mths prior to study screening. Treatment with IV and/or oral corticosteroids (topical corticosteroids are acceptable) within 4 wks of baseline DTI-MRI assessment
- An MS relapse that has occurred within the 30 days prior to randomization and/or the subject has not stabilized from a previous relapse prior to randomization
- Current/previous participation in investigational drug studies
- Subject has any contraindications to fingolimod or natalizumab, as described in the respective Prescribing Information or has any medical condition as described in the warnings and precautions of the respective
Prescribing Information that makes the subject unsuitable for participation in the study
- Subject treated with teriflunomide who did not undergo an accelerated
elimination procedure prior to study screening.
- History or evidence of macular edema on ophthalmologic exam
- History of congenital QT prolongation, unexplained hypokalemia, myocardial infarction, unstable angina, stroke, transient ischemic attack, decompensated heart failure in last 6 mths
- Mobitz type II second degree or third degree AV block or sick sinus syndrome, symptomatic bradycardia, recurrent syncope, or severe untreated sleep apnea
- Baseline corrected QTc (Fridericia [QTcF] or Bazett's [QTcB] formula)
interval =470 ms in females and =450 ms in males
- Treatment with Class Ia (e.g., procainamide, quinidine, ajmaline,
disopyramide) or Class III (amiodarone, bretylium, dofelitide, sotalol,
ibulitide, azilimide) anti-arrhythmic drugs
- Concurrent therapy with drugs that slow heart rate (eg, beta-blockers,
heart-rate lowering calcium channel blockers such as diltiazem,
verapamil or digoxin), prolong the QTc interval, or are potent inducers of
CYP450
