Active clinical trials for "Motor Neuron Disease"

In this Phase 1 double-blind, placebo-controlled study, adult symptomatic patients with amyotrophic lateral sclerosis (ALS) carrying a superoxide dismutase 1 (SOD1) gene mutation thought to be causative of ALS, will be randomized to receive single ascending doses of ARO-SOD1 administered by intrathecal (IT) infusion. The study is primarily intended to evaluate safety, but will also evaluate the effect of ARO-SOD1 on SOD1 cerebrospinal fluid (CSF) levels as a biomarker of pharmacodynamic (PD) effect, therefore lumbar punctures will be required at timepoints throughout the study. Participants whose SOD1 CSF levels have recovered to a satisfactory level may rescreen and rerandomize into higher dose cohorts; or if unable or unwilling to rescreen may enroll into an open-label study to be added by amendment when supported by nonclinical data for multidose administration.

Amyotrophic lateral sclerosis (ALS) is a kind of motor neuron degeneration disorder without effective therapy. This registered cohort study will provide further insights into the clinical course of ALS, and investigate disease-relative risk factors and the genetic background of Chinese ALS patients.

Background: Amyotrophic lateral sclerosis type 4 (ALS4) is an inherited motor neuron disease. People with ALS4 have a change in the amount of RNA and DNA that bind together. This binding of RNA with DNA forms units called R-loops. Researchers want to learn how R-loops are related to ALS4. To do this, they will study people with inherited neurological conditions that may affect R-loop levels. These include ALS4, progressive external opthalmoplegia with mitochondrial deletions (PEOB2), Aicardi-Goutieres syndrome (AGS), and ataxia and oculomotor apraxia type 2 (AOA2). Objective: To learn how the binding of RNA with DNA (R-loops) is related to neurological disease. Eligibility: People age 5 and older with ALS4, PEOB2, AGS, and AOA2. Healthy relatives and nonrelatives are also needed. Design: Participants may be screened with a review of x-rays and other medical records. Healthy relative and nonrelative participants will have 1 visit. All other participants will have 4 visits over 3 years. At visits, participants will undergo some or all of the following: Medical history Physical exam Tests of muscle strength and volume and physical function Blood tests Pregnancy test (for some females) Skin biopsy of forearm Magnetic resonance imaging (MRI) Dual x-ray absorptiometry (DEXA). Some tests are optional. The MRI uses a magnetic field and radio waves to take pictures. Participants will lie on a table that slides in and out of the scanner. The scanner makes noise. They will get earplugs. The DEXA scan uses x-rays to take pictures. MRI and DEXA will be used to measure muscle, fat, and lean body mass. ...

This study aims to measure the quality of life of ALS patients by the SRI questionnaire, in two distinct patient groups : Patient requiring initiation of NIV, and patients 24 hours dependent on NIV This study also seeks to assess the quality of life of the caregivers with the Zarit Burden interview in those two populations

This is a prospective study in a cohort of about 45 patients with ALS participating in the Neurosense PrimeC drug study (NCT05357950). This study aims to evaluate the correlation between oculometric measures and clinical endpoints. Subjects will be evaluated every 2 months during a time period of 18 months. The evaluations will include ALSFRS-R examination, as well as an oculometric evaluation for eye movements.

The specific aims of this study are to: Determine if a painless and quick measurement of muscle activity using surface electrodes can help with the diagnosis of ALS. Specifically, we ask if a measure of intermuscular coherence (IMC-βγ), when added to current diagnostic criteria (Awaji criteria), can differentiate ALS from mimic diseases more accurately and earlier than currently possible. Characterize IMC-βγ in neurotypical subjects by age, sex, race, and ethnicity. Follow a cohort of ALS patients longitudinally to determine if IMC-βγ changes with ALS disease progression and whether such changes correlate with functional and clinical scores, or survival.

Amyotrophic Lateral Sclerosis (ALS) is the most common neurodegenerative disease affecting the motor neuron. Currently, there is no diagnostic test and no examination that can predict the evolution of this pathology. The search for diagnostic and prognostic biomarkers is therefore essential for a better understanding of the pathophysiology of ALS, which remains poorly understood, and also for better clinical management. The ocular surface, made up of liquid elements, tears, and cells, is an accessible anatomical-physiological entity that has demonstrated its usefulness in the identification of biomarkers in neurodegenerative diseases such as Parkinson's or Alzheimer's. To date, no study has explored the ocular surface as a biomarker in ALS

Recently two staging systems have been proposed for amyotrophic lateral sclerosis (ALS), based on clinical milestones The King's college clinical staging system (1) and ALS Milano-Torino Staging (ALS-MITOS) (2). Further research to validate and develop an accurate staging system in different populations will improve our understanding of its pathogenesis, disease activity and progression. General objective : To validate the two previously proposed staging system and to test the interest of considering Neurofilament biomarkers in these systems. Specific objectives: 1) To validate the two classification systems in an independent cohort of patients with ALS followed-up in the ALS expert center of Limoges (France) 2) To assess the interest of Nf biomarkers to predict neurological decline

The purpose of this study is to determine whether nebulized RNS60 is effective in the treatment of amyotrophic lateral sclerosis (ALS).

A prospective and retrospective cohort study of about five years will be performed on blood and cerebrospinal fluid samples taken for diagnostic reasons from recruited patients within the Neuromed Neurology Unit. Subjects with other chronic neurodegenerative diseases such as Amyotrophic lateral sclerosis (ALS), Alzheimer's disease (AD) and Parkinson's disease (PD), and healthy subjects subjected to blood sampling and / or lumbar puncture for clinical reasons will be recruited As control groups.
