Filter by:There is no cure to arrest or delay SBMA progression. It is estimated that ~1000 individuals are affected by SBMA in Italy at any given time (prevalence: 1.5/100000) with an annual incidence of 0.19/100000 males. Here, we are going to test the potential of beta2-agonist stimulation on muscle as a therapeutic avenue for SBMA. We have provided pre-clinical evidence that β-agonist stimulation may be a therapeutic strategy for SBMA. Moreover, we have shown that beta2-agonists are effective in improving motor function without relevant adverse events in a small cohort of SBMA patients. To establish safety and efficacy of clenbuterol as a cure for SBMA, we are conducting a multicenter, phase II, randomized, double-blind, parallel-group, single dose, placebo-controlled trial. Indeed, based on our preliminary data, some concerns remain to be addressed.
This is a data repository for multi-site multi-protocol clinic-based Natural History Study of ALS and Other Motor Neuron Disorders (MND). All people living with ALS or other MNDs who attend clinics at the Study hospitals (sites) are offered to participate in the Study. The Sites collect so-called Baseline information including demographics, disease history and diagnosis, family history, etc. At each visit, the Sites also collect multiple disease-specific outcome measures and events. The information is captured in NeuroBANK, a patient-centric clinical research platform. The Sites have an option to choose to collect data into 20+ additional forms capturing biomarkers and outcome measures. Captured data after its curation are anonymized (all personal identifiers and dates are being removed), and the anonymized dataset is shared with medical researchers via a non-exclusive revocable license.
This is a phase 1/2a randomized, double-blind study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of study drug AJ201 in subjects with Spinal and Bulbar Muscular Atrophy (SBMA).
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.
Background: SBMA is an inherited chronic disease. It affects males in mid to late adulthood. It causes slowly progressive weakness of muscles and hand tremors. Researchers want to learn more about the effects of SBMA. Objective: To identify measurements that change over time in SBMA, including tests of muscle strength and function, as well as measurements of muscle and fat size. Eligibility: Men over the age of 18 both with and without a history of SBMA. Design: Participants will have a medical history, physical exam, and blood and urine tests. They will have neuromuscular ultrasound. They will have a lumbar puncture to obtain spinal fluid. For this, a needle will be inserted into the spinal canal in the lower back. Participants will have muscle strength and function tests. These tests may include pushing, pulling, rising from a chair and sitting back down, and/or walking. During these tests, they may wear an accelerometer (activity tracker) on their wrist. Participants will get an activity tracker to wear on their wrist for 10 days at home every 3 months. Participants with SBMA will also have lower limb magnetic resonance imaging (MRI) and optional whole-body MRI. They will have lung function tests. They will have speech and swallow tests. They will complete questionnaires. They may have optional body scans to measure bone density and lean body mass. They may have optional muscle biopsies. For biopsies, a needle will be used to take a small piece of muscle from the leg. Participants with SBMA will have 5 study visits over 2 years (every 6 months). Participants without SBMA will have 1 study visit.
This study proposes to identify acoustic and perceptual markers related to upper motor neuron (UMN) degeneration and lower motor neuron (LMN) degeneration in the dysarthria of patients with amyotrophic lateral sclerosis (ALS) which involves the degeneration of both systems. ALS patients will be gathered in clinical groups according to electromyogram (EMG) and clinical signs observed in the bulbar site. UMN signs are defined as jaw clonus, gag reflex and pseudobulbar features (lability). LMN signs are defined as lingual atrophy and fasciculations. The dysarthria will be compared to dysarthria of patients involving an exclusive UMN system degeneration (in primitive lateral sclerosis) and an exclusive LMN system degeneration (Kennedy's disease). Patients will be compared to the controls who permitted to establish the standards of the "MonPaGe" tool. MonPaGe is a computerized tool based on a multidimensional and quantified assessment of voice and speech, by a set of targeted acoustic and perceptual criteria.
The purpose of this survey is to evaluate the long-term safety and efficacy of leuprorelin acetate injection kit 11.25 mg in patients with spinal and bulbar muscular atrophy (SBMA) in the routine clinical setting.
Kennedy disease is an inherited neuromuscular disorder that is characterized by progressive muscle wasting and weakness. It typically starts with muscle spasms and tremors in the arms, followed by muscle weakness and atrophy of muscles in the arms and legs. The facial and bulbar muscles are also involved. However, the muscle involvement pattern has not been investigated systemically in Kennedy disease. The primary aim of the study is to investigate the muscle involvement in patients with Kennedy disease using MRI. Secondary aims are to examine disease severity and to test MRI as a potential outcome measure for future clinical trials in Kennedy disease. Approximately 40 patients with Kennedy disease and 20 gender and age matched healthy voluntary controls will be recruited. The study consists of one visit per subject lasting 4-5 hours.
We want investigate if high intensity training can increase daily functionality without causing muscle damage in patients Spinal and Bulbar Muscular Atrophy . We want to study if there is a difference in effect with supervised and unsupervised training. Furthermore we want to study if a supervised training program will motivate participants to continue training by the end of the program.
Background: - Spinal and bulbar muscular atrophy (SBMA) is an inherited disease. It causes weakness in muscles used for swallowing, breathing, and speaking. SBMA mainly affects men, but women can carry the gene for it. Researchers think there may be a link between SBMA and excess fat in the liver. Objective: - To look for fatty liver and liver injury in people with SBMA, people with motor neuron disease, and people who carry the gene for SBMA. Eligibility: - Adults 18 years and older who have SBMA, have motor neuron disease, or are carriers of SBMA. - Healthy adult volunteers. Design: - Participants will be screened with medical history, physical exam, and blood tests. - Participants will have 1 outpatient visit of 1-2 days. Women will have a urine pregnancy test. All participants will have: - Blood tests. - Liver ultrasound. A probe is placed on the abdomen at certain locations and angles and takes pictures. The painless procedure takes 20-30 minutes. - Liver magnetic resonance imaging (MRI) scan. The MRI scanner is a metal cylinder with a magnetic field. Participants will lie on a table that slides in and out of it. They will be in the scanner for about 30 minutes. They will get earplugs for loud noises. - Some participants with abnormal liver testing will have a biopsy (small piece) of the liver taken. The biopsy site will be located with ultrasound, then cleaned and numbed. The physician will quickly pass a needle in and out of the liver while the participants holds their breath. Afterward, participants will be monitored in bed for 6 hours. - Participants may return for follow-up and another 1-2 day outpatient visit yearly for up to 2 years.
