All
18 Years to 55 Years old
This study is NOT accepting healthy volunteers
Inclusion Criteria:
Participant(s) must meet all of the following criteria to be eligible for this study:
• Diagnosis of Multiple Sclerosis (MS) according to the 2017 McDonald Criteria
• (Kurtzke) Expanded Disability Status Scale (EDSS) ≥ 2.0 and ≤ 5.5 at the time of randomization (Day 0)
• T2 abnormalities on brain Magnetic Resonance Imaging (MRI) that fulfill the 2017 McDonald MRI criteria for dissemination in space --A detailed MRI report or MRI images must be available for review by the site neurology investigator.
• Highly active treatment-resistant relapsing MS, defined as ≥ 2 episodes of treatment failure in the 36 months prior to the screening visit (Visit -2). The two treatment failure events need not occur during treatment with different Disease- modifying Therapy (DMT), but must meet all the criteria as described below:
• Each episode of treatment failure must occur following ≥ 3 months of treatment with an FDA-approved DMT for relapsing forms of MS, or with rituximab or ofatumumab, and
• At least one episode of treatment failure must occur with an oral agent or a monoclonal antibody, specifically: dimethyl fumarate (Tecfidera®), diroximel fumarate, teriflunomide (Aubagio®), cladribine (Mavenclad®), daclizumab (Zinbryta®), siponimod (Mayzent®), ozanimod, fingolimod (Gilenya®), rituximab (Rituxan®), ocrelizumab (Ocrevus®), natalizumab (Tysabri®), alemtuzumab (Campath®, Lemtrada®), or ofatumumab (Arzerra®), and
• At least one episode of treatment failure must have occurred within the 12 months prior to the screening visit (Visit -2), and
• At least one episode of treatment failure must be a clinical MS relapse (see item d.i. below). The other episode(s) must occur at least one month before or after the onset of the clinical MS relapse, and must be either another clinical MS relapse or MRI evidence of disease activity (see item d.ii. below): i. Clinical MS relapse must be confirmed by a neurologist's assessment and documented contemporaneously in the medical record. If the clinical MS relapse is not documented in the medical record, it must be approved by the study adjudication committee, and ii. MRI evidence of disease activity must include ≥ 2 unique active lesions on a brain or spinal cord MRI. A detailed MRI report or MRI images must be available for review by the site neurology investigator. A unique active lesion is defined as either of the following:
• A gadolinium-enhancing lesion, or
• A new non-enhancing T2 lesion compared to a reference scan obtained not more than 24 months prior to the screening visit (Visit -2).
• Candidacy for treatment with at least one of the following high efficacy DMTs: Cladribine, natalizumab, alemtuzumab, ocrelizumab, rituximab, and ofatumumab (after approval by the FDA for relapsing MS). --Note: Rituximab, ofatumumab, and ocrelizumab are considered equivalent for candidacy. Candidacy for treatment for each DMT is defined as meeting all of the following:
• No prior treatment failure with the candidate DMT, and
• No contraindication to the candidate DMT, and
• No treatment with the candidate DMT in the 12 months prior to screening.
• Insurance or public funding approval for MS treatment with at least one candidate DMT, and
• Ability to comply with study procedures and provide informed consent, in the opinion of the investigator.
Exclusion Criteria:
Subject(s) who meet any of the following criteria will not be eligible for this study:
• Diagnosis of primary progressive Multiple Sclerosis (MS) according to the 2017 McDonald criteria
• History of neuromyelitis optica or anti-myelin oligodendrocyte glycoprotein (anti-MOG) antibodies associated encephalomyelitis
• Prior treatment with an investigational agent within 3 months or 5 half-lives, whichever is longer
• Either of the following within one month prior to randomization (Day 0):
• Onset of acute MS relapse, or

• Initiation of natalizumab, alemtuzumab, ocrelizumab, or rituximab between screening visit (Visit -2) and randomization (Day 0)

• History of cytopenia consistent with the diagnosis of myelodysplastic syndrome (MDS)
• Presence of unexplained cytopenia, polycythemia, thrombocythemia or leukocytosis
• History of sickle cell anemia or other hemoglobinopathy
