Beschreibung
Inclusion Criteria:
- Diagnosed with relapsing forms of MS
- > 18 years of age at the time of initiation of de-escalation
- No evidence of new inflammatory disease activity (no new T2/contrast enhancing lesions, absence of relapses) for at least two years prior to de-escalation
- Have had multiple sclerosis related symptoms at least 3 years prior to baseline visit.
- Taking an anti-CD20 therapy most recently as a DMT continuously for at least one year (have received at least 2 courses) prior to de-escalation.
- Are 6-12 months from their last anti-CD20 infusion
- Willing to follow the protocol
- Able to undergo a brain MRI without anesthesia
Exclusion Criteria:
- Any progression of neurological symptoms in the year prior to the screening visit that would be consistent with progressive MS.
- Use of any non-FDA-approved DMT or systemic corticosteroids in the last 2 years. (Note: Use of inhaled or topical steroids are not an exclusion criteria. Also, use of oral steroids for no greater than 14 days given for a non-MS condition is not exclusionary).
- IgG levels <300 mg/dL
- lymphocytes <800 cells/mm3
- EDSS >6.5
- Is considering pregnancy at the screening visit
- Prior use of alemtuzumab, mitoxantrone, cyclophosphamide, methotrexate, cyclosporine or any experimental MS treatment in the last 5 years.
- Prior allergy to Vumerity
- Other significant medical or psychiatric illness, if uncontrolled. Examples: uncontrolled hypertension, uncontrolled diabetes, uncontrolled asthma, uncontrolled depression
- Cancers other than basal cell skin cancers within the last 5 years
- Unable to give informed consent or follow the protocol.
- Unable to undergo brain MRI.
- History of other chronic neurological illnesses that might mimic MS with chronic or intermittent symptoms (i.e. ALS, myasthenia gravis, chronic neuropathy, etc.)

De-escalation therapy to diroximmel fumarate (Vumerity®) or dimethyl fumarate (Tecfidera®)
|
Titration starting with 231 mg twice a day, orally, for 7 days (per United States Product information).
Then continue with 462 mg orally (administered as two 231 mg capsules) twice a day.
Titration will start with 120mg twice a day, orally, for 7 days (per United States product information) and then continue with 240mg twice a day orally.

|---|---|---|
|
Components of No Evidence of Disease Activity (NEDA-3) components (of which are no relapse activity, no MRI disease activity and no confirmed disability progression).
Zeitfenster: From baseline to 24 months
|
Number of subjects not meeting NEDA defined as:
The time with NEDA (primary outcome) will be described using product-limit estimates (Kaplan-Meier plots). With 20 patients, if there is no evidence of disease activity in any patients in 24 months, we are 90% confident that the true rate is below 17%. Similarly with 1, 2, and 3 patients with observable disease activity in 24 months, the true rates are between 0.1-25%, 1-32% and 3-38% respectively. |

Zeitfenster |

|
Neurofilament light levels
Zeitfenster: From baseline to 24 Months
|
Neurofilament light levels: Neurofilament light chain is a biomarker of neuroaxonal injury measured in serum or plasma.
Unit: pg/mL (picograms per milliliter).
Range: Continuous, with higher values indicating greater neuroaxonal damage.
|
From baseline to 24 Months
|
|
Brain parenchymal volume loss (using Icometrix)
Zeitfenster: From baseline to 24 Months
|
Brain parenchymal volume loss (using iCOMETRIX): Volume is quantified from serial MRI scans using the FDA-cleared iCOMETRIX (icobrain) software platform.
Unit: Percentage change in brain parenchymal volume from baseline.
Range: Continuous Negative values indicate brain volume loss; larger negative percentages reflect greater tissue loss.
|
From baseline to 24 Months
|
|
Multiple Sclerosis Functional Composite (MSFC)
Zeitfenster: From baseline to 24 Months
|
Assessment of MS-related disability that evaluates ambulation (Timed 25-Foot Walk), upper extremity function (9-Hole Peg Test), and cognitive processing speed.
Continuous composite score calculated as the mean of standardized z-scores from the three component tests.
Positive scores indicate better function and negative scores indicate worse function.
