Efficacy, Safety, and Tolerability of Plovamer Acetate (Pathway 1)
Relapsing Remitting Multiple SclerosisThis is a Phase 2, randomized, rater-blinded, 5-arm, parallel-group trial that will test 4 doses of plovamer acetate against the active comparator Copaxone in subjects with Relapsing Remitting Multiple Sclerosis (RRMS). The trial will be conducted on an outpatient basis for minimum treatment duration of 40 weeks.

Targeted Lower Extremity Joint Training
Multiple SclerosisThe presence of foot drop limits normal gait. Our prior data has suggested that approximately 30% of MS patients have foot drop. Although we have observed that "task-specific" rehabilitation using the Lokomat can improve ambulation in chronic MS patients, subjects with "foot drop" have difficulty translating task-specific training to normative gait patterns over ground, despite improving speed and endurance. One of the key limitations of the Lokomat is a lack of robot-assisted training for the ankle joint. The Anklebot, an MIT-developed rehabilitation robot for the ankle, has the potential to address this. The device can move throughout three planes and train ankle flexion, extension, inversion and eversion; however, therapy with the Anklebot alone does not train the knee or hip. We plan to test whether subject foot drop and overall gait benefit more from Anklebot therapy alone or a combination of Anklebot and Lokomat.

Relationship Between Oral DMT Burden and Adherence in MS
Multiple SclerosisAdherence1 moreSTATURE is a prospective observational six-arm translation multi-site study that will run for approx. 4.5 years. The primary aim is to measure treatment burden and its relationship to medication adherence across six self-administered oral disease-modifying therapies (cladribine, dimethyl fumarate, fingolimod, teriflunomide, ozanimod, and diroximel fumarate) in multiple sclerosis (MS). The information gained will assist prescribing decision-making; accounting for medication burden at a patient level and potential implications on medication adherence and persistence, thus minimising primary and secondary healthcare costs. Three-hundred and twenty-three individuals with MS will be recruited into the study. Patient-reported outcome measures will be administered via Qualtrics, a secure online data collection tool. Medicare and pharmaceutical benefits scheme (PBS) data will also be collected.

Natalizumab De-escalation to Interferon-beta-1b in Patients With Relapsing-remitting Multiple Sclerosis...
Relapsing-remitting Multiple SclerosisMultiple Sclerosis (MS) is the most common neurological disorder causing disability in young adults affecting approximately 1 in 1.000 people in western countries. The clinical manifestations usually begin at the age of 20 to 40 years with a median age of 28 years at onset with acute episodes of neurological dysfunction, followed by periods of partial or complete remission and clinical stability in between relapses. This relapsing-remitting phase (RR-MS) of the disease is usually followed by progressive clinical disability (secondary progressive phase, SP-MS). At present, there is no cure for MS. Based on the pathological concept that neuroinflammation is the common element leading or contributing to neurodegenerative changes, immune interventions have been introduced into clinical practice such as Natalizumab (Tysabri), a humanized monoclonal antibody. Natalizumab (Tysabri) is indicated as a disease-modifying monotherapy of highly active relapsing MS. The associated risks, especially progressive multifocal leukoencephalopathy, necessitate active monitoring of patients and a continuous discussion of optimum use of this drug. In clinical practice, the question how to manage patients on natalizumab at a higher risk for progressive multifocal leukoencephalopathy remains unresolved. This prospective, controlled (comparison to the period prior to natalizumab treatment), single-arm, open-label, multi-centre, phase IV study aims to evaluating the concept of natalizumab de-escalation to interferon-beta-1b e.o.d in relapsing-remitting multiple sclerosis patients, who consider stopping natalizumab due to a benefit-risk assessment. In particular, to evaluating if interferon beta-1b treatment may be able to overcome the recurrence of significant clinical and radiological disease activity after natalizumab cessation and may keep disease activity better under control as compared to the time prior to natalizumab. The study population includes patients with relapsing-remitting multiple sclerosis (RR-MS) being treated at least for 12 months with natalizumab and having decided to stop natalizumab treatment and to de-escalate their therapy to a first line treatment with interferon beta-1b. They will be treated during 12 months with interferon-beta 1b 250 mcg given subcutaneously every other day. A 12-month follow-up period with the same treatment is planned.

Pilot Study to Assess Dimethyl Fumarate Related GI Symptom Mitigation
Relapsing Remitting Multiple SclerosisSingle site, open label, randomized design in patients with relapsing forms of Multiple Sclerosis. At the Screening Visit, the patient will be given a diary containing the MAGIS scale to be completed once a day for the first two weeks while on Dimethyl Fumarate (DMF), including the titration period. After two weeks or if a patient experiences 3 or more consecutive days of GI symptoms in any category of ≥3.5, the patient will return for a Baseline Visit. The MAGIS diary will be reviewed by the coordinator. Any patient who has reported an average MAGIS score of greater than or equal to 3.5 in at least one of the key categories will be randomized to a standard therapy or treatment arm. Patients who report a MAGIS of less than 3.5 during this period will be terminated from the study at this visit. Patients with an average reported MAGIS of greater than 6.5 at Baseline will be placed in the treatment arm. Patients who are randomized to the treatment arm will be instructed to take 125 mg simethicone and one tablespoon of a high fat food (peanut butter) 10 minutes prior to each DMF dose. If the average MAGIS score is greater than 3.5 in the diarrhea category they will also be instructed to take 2 mg loperamide three times daily. Patients randomized to the standard therapy arm will be instructed to follow the normal dosing regimen for DMF with a food bolus of their choice prior to dosing. If severe symptoms (MAGIS >6.5) are noted at any time post randomization in any MAGIS category, crossover to the treatment arm will be allowed. Both groups will be asked to rate their GI symptoms over the past 24 hours using the MAGIS scale once daily. Both treatment arms will be observed for 6 weeks. MAGIS will be recorded once daily. Patients will return to the clinic at Week 3 and Week 6/End of Treatment for diary and compliance review. After Week 6, patients will be instructed to return to a standard therapy. MAGIS will be recorded for one more week and collected at Week 7/End of Study.

Effectiveness of Ankle Foot Orthoses on Gait in Multiple Sclerosis
Multiple SclerosisThe purpose of this study is to investigate the impact of a specifically designed ankle foot orthosis (AFO, hinged, with tamarack joint and adjustable check strap) on the spatial and temporal gait parameters, electromyography (EMG), and walking endurance, in select individuals living with MS. This orthotic is fabricated to allow ankle range of motion required for normal gait kinematics. Additionally, it controls forward progression of the tibia during the stance phase of gait. This study has three hypotheses 1. Individuals who are fit with the AFO will demonstrate improvements in spatial and temporal gait parameters 2. Individuals who are fit with the AFO will demonstrate improvements in walking endurance, and 3. Individuals who are fit with the AFO will demonstrate improvements in muscle firing profiles/EMG measures.

Evaluation of Muscle Oxidative Capacity Relationship With Muscular Endurance, Fatigue (Multiple...
Multiple SclerosisMultiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system. It is characterized by different progressive forms with periods of flare-ups interspersed with phases of remission. MS manifests clinically with signs of multiple neurological dysfunctions as well as less specific symptoms such as fatigue, the prevalence of which is found to be high in these patients and is independently associated with an alteration in their quality of life. Recently, a non-invasive method for assessing maximal muscle oxidative capacity (mVO2) using optical measurement of muscle oxygenation (near-infrared spectroscopy, NIRS) has been described. Measuring tissue light absorption from a skin sensor facing a muscle, makes it possible to distinguish tissue concentrations of oxyhemoglobin (HbO2) and hemoglobin (Hb). The difference in absorbance of Hb and HbO2 corresponds to the balance of O2 supply and consumption in tissue capillaries, allowing calculation of a time constant (kNIRS, min-1) reflecting mitochondrial function. Current literature provides reference values in young healthy subjects and MS patients. This index could therefore constitute a particularly interesting non-invasive indicator of mitochondrial functioning, usable in the clinic.
