CCMR Two: A Phase IIa, Randomised, Double-blind, Placebo-controlled Trial of the Ability of the...
Multiple SclerosisThe greatest unmet need for people with multiple sclerosis is an effective therapy for the progressive phase. Current treatments suppress the damage caused by the immune system but there is only a limited window in which these can work. Consequently, much of the research community is turning its attention to the process of repair, called remyelination, in which the lining of nerve cells is reformed. This protects nerves from dying and therefore can delay, prevent, or even reverse, disability progression. It has previously been shown that stem cells are already present in the brain that can carry out this process. Clemastine, an anti-histamine drug, can instruct them to become active and has already shown a beneficial effect in a phase 2 trial. Now, more recent experiments have shown that changes take place within these stem cells as they age, which prevents them responding to drugs like clemastine, but that this can be reversed by treatment with metformin, a commonly used anti-diabetes drug. Our goal is to establish whether the combination of metformin and clemastine can promote remyelination in people with MS. We will focus on people with relapsing MS as they will have a greater proportion of nerves healthy enough to allow remyelination to take place, which will maximise the chance of detecting an effect with a smaller sample size. Participants will also continue treatment with a current disease-modifying MS treatment, to reduce the chance of developing new areas of damage, allowing the trial to focus on the repair process. The treatment duration will be 24 weeks, but given the established safety of the proposed medications, we are able to limit the number of visits to the trial centre to ensure participation is not overly burdensome.

WEBCAMS: Walking Exercise for Brain and Cognition in Adults With Multiple Sclerosis
Multiple SclerosisRelapsing-remitting Multiple SclerosisThis study is a randomized controlled trial (RCT) that compares the effects of two different 12-month aerobic walking exercise programs on cognitive processing speed (CPS), brain MRI, and other functional outcomes in 32 adults with multiple sclerosis (MS) who are able to walk without an assistive device but demonstrate slowed CPS. Participants (N=32) will initially undergo screening via telephone, and after satisfying relevant inclusion/exclusion criteria, will provide informed consent, followed by a baseline assessment of CPS remotely via a HIPAA-compliant virtual platform (i.e., Zoom for Healthcare). This assessment will also serve as a screen for ensuring impaired CPS. Following this virtual session, participants will come into Kessler Foundation (KF) and complete a 3-hour baseline assessment (T0) that includes a relatively short battery of neuropsychological tests, a 40-minute MRI scan, tests of walking function, a short questionnaire packet, followed by cardiopulmonary exercise testing on a motor-driven treadmill. Following T0, participants will be randomly assigned into one of the two aerobic walking ET programs that are remotely-delivered and supported by KF research assistants. As the conditions are delivered and supported remotely by KF personnel, the exercise itself takes place in the home/community setting. Both conditions involve behavior coaching via Zoom for Healthcare. The experimental condition involves high-frequency, high-intensity aerobic walking ET that exceeds the published guidelines for physical activity for adults with MS (GEMS+). GEMS + initially involves 10 minutes of moderate intensity aerobic walking exercise for 3 days per week and progresses to upwards of 40 minutes of vigorous intensity aerobic walking exercise for 5 days per week by month 12. The comparison condition involves mild-to-moderate aerobic walking exercise training that approximates published guidelines (GEMS). GEMS initially involves 10 minutes of light intensity aerobic walking exercise for 2 days per week and progresses up to 30 minutes of moderate intensity aerobic walking exercise for 3 days per week. Both conditions further will be monitored based on Fitbit-measured steps per exercise session. Of note, the sample size will be enrolled using 2 overlapping waves (Wave 1 = 14 participants, Wave 2 = 18 participants), 3 months apart. Participants will return to KF at the mid-point (i.e., T6) and end-point (i.e., T12) of the 12-month intervention period to complete the same assessments as T0. The T6 and T12 outcomes will be administered by treatment-blinded research assistants.
High Intensity Functional Training for Individuals With Neurologic Diagnoses and Their Care Partners...
Neurologic DisorderParkinson Disease6 moreIndividuals with and without neurologic diagnoses greatly benefit from participation in regular exercise but the majority are physically inactive. This is an issue for both them and their care partners as their health is often linked. This study aims to examine the long-term physical and psychosocial effects of structured, group-based, high intensity functional training (HIFT) exercise for people with neurologic diagnoses and their care partners.
Who Benefits Most From Cognitive Rehabilitation for Multiple Sclerosis?
Multiple SclerosisOver the last 20 years, there have been many studies investigating the efficacy of attention and memory rehabilitation for people with multiple sclerosis (MS) however, there appears to be a lack of conclusive evidence regarding the true effectiveness of this intervention. This could be because the participant samples recruited to these studies are often extremely varied in terms of socio-demographics and clinical characteristics, and it would be very unlikely that all people with MS would benefit from these interventions uniformly. Therefore, there is a need to explore which subgroups of people with MS benefit most from cognitive rehabilitation so that this information can be used to help clinicians and services make decisions as to whom this intervention is offered. Cognitive rehabilitation is not routinely provided on the NHS due to lack of resources. This research is important as it will allow these resources to be optimised and made available to those who need them, but also to allow clinicians to understand whether their patient is likely to benefit from cognitive rehabilitation before it is offered. The primary aim of this study is to assess the feasibility and acceptability of undertaking a randomised controlled trial (RCT) to investigate the effectiveness of an online group-based cognitive rehabilitation programme with specific groups of people with MS. The secondary aim is to understand the impact that this intervention may have on various aspects of cognition such as memory, attention, and information processing. This will be assessed through various questionnaires and objective neuropsychological tests. In addition, an algorithm has been developed following the secondary data analysis of a large RCT investigating group-based cognitive rehabilitation for people with MS. This algorithm may be able to determine who benefits most from cognitive rehabilitation, we will therefore use this as part of the data analysis to understand if the algorithm has the potential to be an accurate clinical prediction tool. After completion of the cognitive rehabilitation, a small number of participants in the intervention group will be invited to take part in feedback interviews to give their views on the feasibility and acceptability of the group-based online cognitive rehabilitation and provide any suggestions for improvements for future trials.
Vancomycin Study in Multiple Sclerosis (MS)
Multiple SclerosisThe overall goal of this study is to elucidate a mechanism by which vancomycin modulates the gut-brain axis in multiple sclerosis (MS). The gut microbiome plays an important role in autoimmunity, including MS. However, the identity of gut microbes modulating neuroinflammation in MS and their mechanisms of action remain obscure. Hence, here the research team proposes to investigate the effects of vancomycin on the gut microbiota composition, peripheral immune function, and brain MRI lesions in MS patients.
Examining the Effects of a Remotely-delivered, Racially-tailored Exercise Training Program for Immediate...
Multiple SclerosisThe proposed project involves a high-quality randomized controlled (RCT) design that examines the effects of a remotely-delivered, racially-tailored exercise training program for immediate and sustained improvement in walking dysfunction, symptoms, and health-related quality of life (HRQOL) among African-Americans with MS residing in rural environments. The primary analysis will test the hypothesis that those who are randomly assigned into the intervention condition (i.e., exercise training) will demonstrate (a) improvements in outcomes from baseline that (b) are sustained over 4-months of follow-up compared with those in the control condition (i.e., stretching).
Clemastine Fumarate as Remyelinating Treatment in Internuclear Ophthalmoparesis and Multiple Sclerosis...
Multiple SclerosisInternuclear OphthalmoplegiaRationale: Clemastine fumarate has been identified as potential remyelinating therapy for multiple sclerosis (MS). The (long-term) effects of clemastine need to be confirmed in clinical models for MS. Internuclear ophthalmoparesis (INO) may be used as a clinical model for investigating remyelinating therapies by measuring horizontal eye movements with infrared oculography. Furthermore, infrared oculography combined with a single dose of fampridine may be used to identify individuals with MS that are most likely to benefit from remyelinating therapy. Objective: To assess the (long-term) efficacy of clemastine fumarate in improving dysconjugacy of eye movements in patients with internuclear ophthalmoparesis and multiple sclerosis. Secondly, to assess whether a response to a single dose of fampridine can predict the effects of clemastine treatment. Study design: A single-centre double-blind randomized placebo-controlled trial consisting of a 6 months (180 days) treatment period followed by a 30 months follow-up period. Study population: 80 MS patients, age 18-70 years, with INO. Intervention: The intervention group will receive 4 mg of clemastine fumarate twice daily (8 mg/day) for 6 months (180 days), the control group will receive an equivalent amount of placebo. At baseline all participants will receive a single 10 mg dose of fampridine. Main study parameters/endpoints: The primary outcome measure is the change in versional dysconjugacy index (VDI) of area under the curve (AUC) measured by infrared oculography. Secondary outcome measures include changes in other VDI measures (peak velocity per amplitude (PV/Am) and peak velocity (PV)), changes in VDI after single fampridine dose, other oculography parameters (e.g. saccadic latency, anti-saccades), (peripheral) retinal nerve fibre layer (pRNFL) and (macular) ganglion cell inner plexiform layer (mGCIPL) thickness measured by OCT, SDMT, EDSS, high and low contrast visual acuity, subjective visual functioning (NEI-VFQ-25 and NOV-AU questionnaire), quality of life (EQ5D-5L) and fatigue (CIS20R and NFI-MS questionnaire). Nature and extent of the burden and risks: Participation in the study will consist of a total of 7 study visits. Study visits will include physical/neurological examination, infrared oculography, OCT, visual acuity tests, a cognition test (SDMT), 5 questionnaires and blood samples for safety laboratory tests. Considering both clemastine and fampridine are registered and well-established drugs and have been used in clinical practice, the estimated risk of unexpected adverse reactions is low.
