Effect of Noninvasive Ventilation on Lung Function in Amyotrophic Lateral Sclerosis - Full Text View - ClinicalTrials.gov
Amyotrophic Lateral Sclerosis (ALS), or 'Lou Gehrig's Disease', is a fatal disorder that causes progressive degeneration and weakening of the muscles of breathing, leading to breathing insufficiency and eventually breathing failure. This breathing insufficiency is commonly treated with a breathing assistance device, known as noninvasive positive pressure ventilation (NIPPV). While generally well tolerated and accepted, it is not clear whether or to what extent NIPPV in fact helps breathing function: some data suggest that NIPPV preserves breathing function over time, whereas other data suggest that it actually causes breathing function to decline more quickly. No studies have shown what the acute effect of NIPPV is on breathing muscle function in ALS patients.. This study will test the hypothesis that the acute use of NIPPV, at pressure levels that are in common clinical use, will cause measurable changes in tests of breathing function, compared to baseline and to lower levels of NIPPV. We ...https://clinicaltrials.gov/ct2/show/NCT00537446?recr=Open&cond=%22Amyotrophic+Lateral+Sclerosis%22&rank=20

Safety Study of HLA-haplo Matched Allogenic Bone Marrow Derived Stem Cell Treatment in Amyotrophic Lateral Sclerosis - Full...
Amyotrophic lateral sclerosis is a progressive neurodegenerative disease characterized by motor neuron loss. Despite of many trials for disease-modifying, no treatment has so far changed natural course of disease.. The investigators had performed the pre-clinical and clinical studies using autologous bone marrow-derived stem cells in ALS. In the investigators' results of clinical trial, intrathecal injection of autologous bone marrow-derived stem cells is safe and could slow down disease progression and might be used as a disease modifying strategy in patients with ALS.. In the new field, like cell therapy, it is an important issue whether a bone marrow derived mesenchymal stem cells can be used as an allograft. Many investigators had showed that the immunoprivileged and immunosuppressive properties of mesenchymal stem cells result from the absence of major histocompatibility class II antigens and the secretion of T helper type 2 cytokines.. One potential advantage of allogenic bone marrow ...https://clinicaltrials.gov/ct2/show/NCT01758510?recr=Open&cond=%22Neuromuscular+Diseases%22&rank=14
PET Scan of Brain Metabolism in Relation to Age and Disease - Full Text View - ClinicalTrials.gov
The Brain Physiology and Metabolism Section (BPMS) of the National Institute on Aging (NIA) and the Clinical Neuroscience Program (CNP) of the National Institute of Neurological Disorders and Stroke (NINDS) propose to study regional brain phospholipid metabolism in young and old normal volunteers and in patients with Alzheimer disease. The method to be employed, developed from animal studies, involves the intravenous injection of a radiolabeled polyunsaturated fatty acid, [11C]arachidonic acid and measuring regional brain radioactivity using positron emission tomography (PET). A mathematical model is used to calculate regional brain incorporation coefficients k* of [11C]arachidonate into brain. These reflect brain signal transduction and membrane turnover involving phospholipids and the signal transduction and membrane turnover involving phospholipids and the activation of the enzyme, phospholipase A2. PET also will be used in the same subjects to measure regional cerebral blood flow (rCBF), a ...https://clinicaltrials.gov/ct2/show/NCT00001972?cond=%22niemann-pick+disease%22&rank=19
Muscular Biomarkers in Amyotrophic Lateral Sclerosis - Full Text View - ClinicalTrials.gov
Amyotrophic Lateral Sclerosis (ALS), the most common MND, is a fatal adult-onset neuromuscular disease. Due to clinical heterogeneity and absence of biological tools to diagnose ALS, the delay between the first symptoms and diagnosis averages 9-13 months. A group of pathophysiological processes, including oxidative stress and glutamate-mediated excitotoxicity contribute to cell death, but the triggering factor, the timing and the interaction of different cellular events await elucidation . Unknown pathogenesis for most patients means few available treatments. The search for biomarkers that can aid diagnosis, characterize phenotype, define pathophysiology, identify endpoints in trials and measure disease progression is of utmost importance for the field. Some studies have advocated that muscle per se may be impaired by pathogenesis of the diseases. Muscle has been poorly studied and its central role in energetic metabolism suggests that this tissue, quite easily available, should be more ...https://clinicaltrials.gov/ct2/show/NCT02670226?term=Neuromuscular+Diseases&recrs=abc&cond=%22Amyotrophic+Lateral+Sclerosis%22&rank=18

Study of Creatine Monohydrate in Patients With Amyotrophic Lateral Sclerosis - Full Text View - ClinicalTrials.gov
Introduction: Twenty-one ALS patients were enrolled in a placebo controlled pilot study at the Carolinas Neuromuscular/ALS-MDA Center, The University of Texas Health Science Center at San Antonio and The University of New Mexico at Albuquerque. At all time points sampled over a nine month period, patients taking creatine monohydrate had either a significantly greater improvement in their strength or a more modest decline compared to the patients taking placebo. Overall analysis of variance is significant for both an effect of the drug (p=0.002) and time (p, 0.001).The pilot study also showed that quality of life, as measured by ALSFRS-R, correlated significantly with the observed changes in muscle strength (MVIC).. Phase III Study: The primary objective of this study is to determine whether treatment with creatine monohydrate results in an increase in muscle strength relative to placebo in patients with amyotrophic lateral sclerosis (ALS), after three months, and at the end of a nine-month ...https://clinicaltrials.gov/ct2/show/NCT00069186?term=Amyotrophic+Lateral+Sclerosis+

Human Spinal Cord Derived Neural Stem Cell Transplantation for the Treatment of Amyotrophic Lateral Sclerosis - Full Text View ...
These stem cells are called Human Spinal Stem Cells (HSSC) and have been engineered from the spinal cord of a single fetus electively aborted after 8 weeks of gestation. The tissue was obtained with the mother's consent. The cells will be transplanted into the ALS patient's spinal cord after laminectomy, an operation that removes bone surrounding the spine. After the spinal cord is exposed, a device manufactured for this purpose will be mounted onto the patient and will hold a syringe filled with the cells. The syringe will have a needle attached and the needle will enter the spinal cord in specified areas. The device will minimize trauma to the spinal cord by the needle by making the puncture precise and steady and injecting the material at a slow and steady speed.. ALS is a universally fatal neurodegenerative condition that causes weakness leading to paralysis and death. Life expectancy is 2-5 years. The cause is unknown and there is no effective treatment. Previous research has shown that on ...https://clinicaltrials.gov/ct2/show/NCT01348451?term=amyotrophic+lateral+sclerosis&rank=31

Motor-Point Stimulation for Conditioning the Diaphragm of Patients With Amyotrophic Lateral Sclerosis (ALS) - Full Text View -...
The purpose of this study is to demonstrate the safety and efficacy of the NeuRX RA/4 Diaphragm Pacing Stimulation (DPS) System in conditioning the diaphragm of an ALS patient to improve the quality of life and slow the progression to respiratory failure.. Amyotrophic Lateral Sclerosis (ALS, also known as Lou Gehrig's disease or Motor Neuron Disease) is a progressive neurodegenerative disease of unknown cause. One of the most important effects of progressive neuromuscular weakness in patients with ALS is the effect on respiration. Although ALS has no direct effect on the lung, it has devastating effects on mechanical function of the respiratory system. ALS affects all of the major respiratory muscle groups: upper airway muscles, expiratory muscles, and inspiratory muscles. Therefore, all patients with ALS are at significant risk for respiratory complications. Progressive inspiratory muscle weakness in ALS inevitably leads to carbon dioxide retention, inability to clear secretions and hypercarbic ...https://clinicaltrials.gov/ct2/show/study/NCT00420719?show_desc=Y
EEG-Based Brain-Computer Interface Project for Individuals With Amyotrophic Lateral Sclerosis (ALS) - Full Text View -...
Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular condition characterized by weakness, muscle wasting, fasciculations and increased reflexes. Depending on the site of onset, individuals with ALS progressively lose control of their skeletal muscles; bulbar or the extremities. As symptoms worsen and spread, muscle atrophy becomes apparent and upper motor neuron symptoms such as spasticity complicate gait (in lower limb involvement) and manual dexterity (in upper limb involvement). The patients progress to a state of profound disability and have great difficulty in communicating; some may even be entirely 'locked in' to their bodies. The capacity for simple communication could greatly improve their quality of life.. New technologies are giving people with disabilities alternate communication and control options. One such instrument is the EEG-based Brain-Computer Interface (BCI) which can provide both communication and control functions to those who have lost muscle control.
