Filter by:Brief Summary: The goal of the study is to generate a biorepository of longitudinal blood (plasma and serum), cerebral spinal fluid (CSF) and urine linked to genetics and longitudinal clinical information that are made available to the research community. To accomplish these goals, we will enroll 200 Amyotrophic Lateral Sclerosis (ALS) patients and 80 healthy controls from multiple sites, over a 5 year time frame. Additionally, speech measures will be collected on weekly basis at home for all participants. The measurements are performed using a speech recording application installed on their personal device. For a subset of both ALS and healthy participants, we will also collect at-home vital capacity on a weekly basis. It is expected that increased frequency data sampling of these outcome measures will help in better tracking of disease progression. Biofluids and clinical information are collected over a 20-month time frame for each individual enrolled in the research study. ALS participants will be coming to clinic for 5 study visits with a 4-month interval between visits. Healthy participants will be coming for 2 study visits with a 12-month interval between visits. These samples and clinical information will be stored in a de-identified manner and made available for investigators to use in future research studies.
A two-arm, individual participant randomised controlled, assessor-blinded trial in 7 MND care centres across Australia will be undertaken.
Multi-Center, Randomized, Double-Blinded Phase 3 Study to Evaluate the Efficacy, Safety, and Tolerability of IMU-838 versus Placebo in Adults with Relapsing Multiple Sclerosis (ENSURE-1)
The 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.
The purpose of this study is to assess the effectiveness after using a new individualized-health e-library app named SavvyHealth among people with multiple sclerosis.
The purpose of this study is to implement the person-centered internet-based Health Action Process Approach to promoting physical activity in people with Multiple Sclerosis (i.e., eHAPA-MS online intervention) and assess the intervention's effectiveness and adherence.
Pediatric-onset multiple sclerosis (POMS) is a chronic, autoimmune and inflammatory disease of the central nervous system that begins before the age of 18 years. POMS patients are affected in terms of physical capacity, cognitive status and fatigue compared with their healthy peers that has been reported. It has been reported that although individuals with MS with low disability levels do not have respiratory complaints, respiratory parameters may be affected. Therefore, it is necessary to evaluate respiratory capacity, respiratory muscle strength and fatigue levels of POMS patients. Evaluations will help prevent future complications by detecting any existing problems early.
This double-blind, double-dummy study will evaluate the safety and efficacy of ocrelizumab compared with fingolimod in children and adolescents with relapsing-remitting multiple sclerosis aged between 10 and < 18 years over a duration of at least 96 weeks.
This study evaluates the effectiveness of N-acetyl cysteine (NAC) in the treatment of progressive multiple sclerosis. Half of the patients will receive NAC, while the other half will receive a placebo.
Amyotrophic lateral sclerosis (ALS), is a rapidly progressive neurodegenerative disorder, usually leading to death from respiratory failure in 3-5 years. Riluzole, the only drug currently available, only modestly prolongs survival and does not improve muscle strength or function. In ALS, loss of functional motor neurons is initially compensated for by collateral reinnervation and strength is preserved. In the majority of ALS patients, as the disease progresses, compensation fails leading to progressive muscle weakness. Conversely, in long-term ALS survivors, slow functional decline is correlated with their ability to maintain a successful compensatory response to denervation over time. Compensatory collateral reinnervation is thus essential for functional motor preservation and survival, and elucidation of the molecular mechanisms involved is crucial to help identify new therapeutic targets. Energy metabolism and glucose homeostasis modifications also influence disease clinical course but the mechanisms by which they contribute to the progression of ALS are unknown. Weight loss is an independent negative prognostic factor for survival and, by contrast, ALS risk and progression are decreased in individuals with high body mass index and non-insulin-dependent diabetes mellitus. Insulin shares many common steps in its signaling pathways with insulin-like growth factor 1 (IGF-1), and is thus at the interface between glucose homeostasis regulation and maintenance of muscle mass. However, the contribution of insulin signaling to preservation of muscle innervation and function in ALS has never been investigated. With this study, we aim to determine the role of insulin signaling pathways in maintenance of collateral reinnervation and muscle function in ALS. We will also investigate the link with the disease-modifying effect of metabolic and glucose homeostasis perturbations, by identifying the contribution of metabolic profiles to preservation of skeletal muscle innervation and motor function in patients with ALS. For this purpose, we will determine the whole-body and skeletal muscle metabolic profiles of 20 patients with ALS and correlate these results to collateral reinnervation ability quantified on muscle biopsy specimens. For each patient, we will use both clinical and electrophysiological methods to evaluate motor function and motor neuron loss over time. Body composition, insulin secretion, insulin resistance level and serum concentrations of IGF-1 axis components will be determined. A motor point muscle biopsy will be performed for morphological analysis of neuromuscular junctions and quantification of innervation by confocal microscopy. Activation of insulin/IGF-1 canonical signaling pathways and metabolic pathways of glucose homeostasis will be quantified in muscle specimens. Skeletal muscle and whole-body metabolic parameters will be analyzed together and correlated with clinical assessment of motor function, electrophysiological data, and innervation quantification results. For comparison, 10 healthy subjects of similar age and 10 patients with spinal and bulbar muscular atrophy - a slowly progressive motor neuron disorder with maintenance of effective collateral reinnervation - will be used as controls. This study will be the first to address the question of the contribution of insulin signaling pathways and metabolic profiles in maintenance of muscle reinnervation and function in ALS patients. The molecular mechanisms identified will be new targets for future treatments promoting compensatory reinnervation and slowing disease progression in ALS. Ultimately, this translational project could have a significant therapeutic impact in disorders with muscle denervation and collateral reinnervation as a compensatory mechanism, such as spinal muscle atrophy or peripheral neuropathies.
