ALS (Amyotrophic Lateral Sclerosis)

Eighteen million people worldwide are affected by speech disorders. Locked-in syndrome (LIS) represents the most extreme form of communication disability resulting from motor impairment. In France, the Association du Locked-In Syndrome (ALIS) reports approximately 500 individuals with LIS, most of whom live at home. The quality of life of people with LIS depends strongly on their ability to communicate, and speech synthesis is the mode of communication restoration most desired by individuals with LIS. Several surveys have shown that improving communication abilities in these individuals leads to a significant improvement in their quality of life as well as that of their caregivers. Natural speech allows the production of an average of 150 words per minute. Non-invasive communication methods, whether based on residual motor function (eye-blink code) or on brain-machine or brain-computer interfaces (Brain-Computer Interface, BCI) using scalp electroencephalographic (EEG) signals, involve a high cognitive load and have low efficiency (spelling only a few letters per minute). Invasive BCIs for speech rehabilitation aim to overcome the limitations of non-invasive devices (cognitive overload and slow speech rate). The intention to act (the act of speaking) is predicted by an algorithm based on the direct decoding of neuronal activity from the sensorimotor cortex (the area where articulatory muscles are represented). To date, studies testing speech rehabilitation BCIs in humans remain rare. A subdural electrocorticographic (ECoG) invasive BCI enabled speech decoding (words and sentences from a limited repertoire) for chronic use (2 years). Real-time control of an on-screen cursor allowing spelling of up to 90 letters per minute (equivalent to text messaging) has also been achieved using an intracortical invasive BCI (Utah Array). Very recently, up to 60 words per minute were produced using an intracortical invasive BCI (Utah Array) implanted in the ventral premotor cortex, although with a connector potentially contaminated by acoustic audio feedback. Furthermore, these devices still rely on transcutaneous connectors, which may be sources of infection and prevent routine daily-life use. In summary, there is currently no fully implantable, wireless invasive "speech BCI" with real-time speech synthesis suitable for long-term home use. The present study will use an intracranial extradural invasive BCI combined with a speech synthesizer, with the aim of developing a communication tool suitable for everyday use. More specifically, the SpeechBCI protocol will propose two complementary BCI approaches in the same subject: a speech BCI (primary objective, BCI\_PAROLE device) and a cursor BCI (secondary objective). Both BCIs will use the WIMAGINE intracranial epidural system, enabling ECoG signal acquisition with a very limited risk of infection and brain injury and providing signals that are more stable over time compared with intracortical or subdural ECoG devices that retain transcutaneous connectors. These systems will allow long-term and ecological use, as the WIMAGINE implant is wireless and offers excellent long-term signal stability. The WIMAGINE implant has already been successfully tested for controlling an exoskeleton in a tetraplegic subject (operational for over 6 years) and very recently for controlling walking in real-life conditions via a spinal cord stimulator in a paraplegic individual. The BCI\_PAROLE device will integrate a speech synthesizer providing real-time auditory feedback to the speaker. The BCI-CURSEUR device will allow the subject to control an on-screen cursor to access various communication functionalities (web access, emails, chats, etc.). This will provide a complementary communication solution to real-time speech production. The hypothesis of this stydy is that the intention to speak (attempted speech) will be decoded by the BCI\_PAROLE device in individuals with LIS because, as with limb paralysis, paralysis of articulatory and phonatory muscles does not prevent the corresponding cortical map from producing specific signals. Similarly, the BCI-CURSEUR device will decode the intention to move a cursor and perform actions on a computer screen. Neuronal electrical signals will be recorded bilaterally from the ventral motor cortex (representation of lips, cheeks, tongue, palate, and larynx-the vocal tract) and from the dorsal part of the motor cortex (larynx and hand, the latter for controlling a two-degree-of-freedom cursor), using a total of 128 electrodes (64 on each cerebral hemisphere). The implant will be optimally positioned over speech motor areas using preoperative functional imaging in order to optimize speech decoding by the BCI\_PAROLE device.

The aim of this study is to assess the impact of a probiotic formulation on participants with ALS-FTDSD. It is hypothesized that participants given the probiotics will have different lipid profiles compared to participants receiving the placebo at different time points.

The goal of this clinical trial is to evaluate whether tofersen is safe and effective in adults with non-SOD1 ALS. Tofersen is currently approved by the U.S. Food and Drug Administration to treat SOD1-ALS. The main questions it aims to answer are: * Does tofersen lower the levels of neurofilament light chain (NfL) in the blood and CSF of adult participants with non-SOD1 ALS? * Is tofersen safe and tolerable for adult participants with non-SOD1 ALS? * Does tofersen affect other measurements such as clinical outcomes and quality-of-life measures in participants with non-SOD1 ALS? Participants will : * Receive 100mg tofersen via lumbar puncture for 24 weeks. The doses are at the following time points: Weeks 0, 2, 4, 8, 12, 16, 20, and 24. * Complete 2 follow-up visits following the end of the dosing period at Weeks 28 and 32. * Complete a variety of questionnaires and outcome measurements such as strength and breathing testing.

The purpose of this Expanded Access Program is to provide tazbentetol to ALS patients who are not eligible to enroll in an ALS clinical trial. This Expanded Access Program will assess safety and tolerability, and clinical efficacy of tazbentelol.

INdependence Through Endovascular Neuroprosthetic Technology (INTENT): an Early Feasibility Study

This study is testing a tongue exercise program for people living with ALS to see if it can help support speech and swallowing. All participants will receive the treatment, and researchers will measure changes over time by comparing each person's results to their own earlier results. People who join the study will have two in-person visits and four weekly telehealth sessions with a speech-language pathologist. During these sessions, participants will practice tongue resistance exercises, complete speech and swallowing tasks, and answer surveys about their experience. They will also use a small device at home to measure tongue strength and swallowing. The exercise program involves pressing the tongue against a device several times a day, five days per week, for five weeks. Researchers want to learn if this program is safe, practical, and helpful for people with ALS.

The goal of this clinical trial is to evaluate whether psilocybin therapy can effectively treat depression and psychological distress in adult patients with COPD, ALS, MS, or APD who have at least 6 months life expectancy. The main questions it aims to answer are: * Can psilocybin therapy safely reduce depressive symptoms compared to low-dose control? * Will the therapeutic effects be rapid and sustained over a 6-month period? Researchers will compare patients receiving two escalating doses of psilocybin (15mg followed by 25mg) against those receiving two low doses (1mg) to see if the higher doses lead to greater improvements in depression, anxiety, demoralization, and quality of life. Participants will: * Attend three preparation sessions with psychotherapists (1-2 hours each) * Undergo two supervised psilocybin dosing sessions (6-8 hours each) * Complete five integration therapy sessions following the dosing sessions * Participate in follow-up assessments at 6 weeks, 3 months, and 6 months * Have access to a digital care platform and peer support groups during the 6-month follow-up period * Optional: Control group participants may receive one high-dose psilocybin session (25mg) after the initial study period

Many individuals with severe motor impairments rely on Assistive Technologies (ATs) or Brain-Computer Interfaces (BCIs) to interact with digital devices such as their computers. Clinicians and researchers currently lack a common framework to objectively quantify how much a given AT or BCI improves real-world function or to compare across tools. This project seeks to address this gap by developing a standardized method to objectively assess or compare the functional benefit of these tools on digital independence, i.e., the ability to independently operate computers, phones, and other digital systems, by creating a unique Digital Assessment Interface (DAI). This assessment will be a simulation of online and digital activities that prior work has determined is important to functional daily living in the digital domain. Participants will complete this assessment with various ATs and BCIs, and these scores will be used to create an index, which will be comprised of performance outcomes, clinician-reported outcomes, and patient-reported outcomes. The tool aims to quantify and compare digital task performance across devices and user populations. The primary objective of this study is to develop an index. The index will quantify functional performance of individuals using various ATs and BCIs. The secondary objectives are to extensively evaluate the psychometric properties of the index, such as the validity, responsiveness, reliability, and floor/ceiling effects both globally and across different devices and impairment levels, ensuring that it can reliably measure the impact of an AT or BCI on a user's ability to independently operate digital systems; and to characterize the familiarization and use of specific BCI and AT systems with reference to a normative healthy control population.

The aim of this study is to describe national trends over the past 10 years in patients receiving invasive home mechanical ventilation (HMV) in Denmark. This includes indications for invasive HMV, diagnostic groups, and one-year mortality.

The Swedish BioFINDER 2 study is a new study that will launch in 2017 and extends the previous cohorts of BioFINDER 1 study (www.biofinder.se). BioFINDER 1 is used e.g. to characterize the role of beta-amyloid pathology in early diagnosis of Alzheimer's disease (AD) using amyloid-PET (18F-Flutemetamol) and Aβ analysis in cerebrospinal fluid samples. The BioFINDER 1 study has resulted in more than 40 publications during the last three years, many in high impact journals, and some the of the results have already had important implications for the diagnostic work-up patients with AD in the clinical routine practice. The original BioFINDER 1 cohort started to include participants in 2008. Since then there has been a rapid development of biochemical and neuroimaging technologies which enable novel ways to the study biological processes involved in Alzheimer's disease in living people. There has also been a growing interest in the earliest stages of AD and other neurodegenerative diseases. With the advent of new tau-PET tracers there is now an opportunity to elucidate the role of tau pathology in the pathogenesis of AD and other tauopathies. The Swedish BioFINDER 2 study has been designed to complement the BioFINDER 1 study and to e.g. address issues regarding the role of tau pathology in different dementias and in preclinical stages of different dementia diseases. Further, the clinical assessments and MRI methods have been further optimized compared to BioFINDER 1. Detailed assessments of motor aspects and dual task performance, which is part of a sub-study named Motor-ACT: "Motor aspects and activities in relation to cognitive decline and brain pathologies, has been added to further optimize assessment of motor function.

Diagnosis of ALS/FTD disease spectrum is challenging because it largely relies on clinical symptoms. Identifying novel biomarkers is essential for a paradigm shift towards a more precise biological-based diagnosis. To achieve this aim, having access to proper specimens and analytical methods is crucial. Our team of experts in neurology, biology, chemistry, physics, and AI will explore ALS/FTD from novel perspectives using transcriptomics, proteomics, genomics and other innovative approaches to analyzing easily accessible tissues. The seed amplification assay (SAA) will be also exploited to detect pathological TDP-43. This project aims to create disease fingerprints useful for patient stratification and monitoring of disease progression, and to evaluate the therapeutic efficacy in clinical trials, thus overcoming the limits of clinical interpretation. Discovering new biomarkers and cellular pathways will improve the diagnosis and treatment of these devastating diseases.

The search for diagnostic biomarkers that can be used routinely is a major challenge to manage Amyotrophic lateral sclerosis (ALS) in order to characterize the pathophysiology and accelerate the management of the disease. Some non-specific biomarkers have been proposed (Neurofilaments, TDP-43) but their diagnostic value remains controversial. This study aims to identify ALS-specific platelet biomarkers using targeted and untargeted multi-omic approaches, in order to enable differential diagnosis between ALS and other motor neuron diseases.

Virtual Reality (VR) is gaining traction as a new and innovative leisure to augment healthcare services. Several benefits of the leisure experience, such as distraction and full sensory immersion, have demonstrated a potential to significantly impact the field of healthcare through pain reduction, anxiety reduction, and is seen as an innovative approach to motor learning. Persons with ALS (pwALS) have a high prevalence of anxiety over the course of their illness, which has a negative impact on their quality of life, and the quality of life of those closest to them. The use of VR for anxiety management and subsequent quality of life improvement has yet to be explored in the ALS population. For individuals with ALS, VR can be both (1) an escape from the reality of living day to day with a progressive fatal diagnosis; and (2) the opportunity to potentially improve anxiety, both of which are linked to the quality of life of individuals living with ALS. Our hypothesis is that a simple and accessible home VR-guided relaxation exercise program can improve subjective anxiety symptoms in a person living with ALS and subsequently improve quality of life.

The purpose of this study is to evaluate how well LY4256984 is tolerated and what side effects may occur in participants with sporadic amyotrophic lateral sclerosis (ALS). The study drug will be administered intrathecally (IT) into the spine. Blood tests will be performed to check how much LY4256984 gets into the bloodstream and how long it takes the body to eliminate it.

This clinical study is in participants with Amyotrophic Lateral Sclerosis and is designed to evaluate the safety and tolerability of the gene therapy CTx1000.

The goal of the Healey ALS MyMatch Common Screening Protocol (MCSP), an observational study, is to identify individuals with ALS who may be eligible to be matched to a currently enrolling ALS MyMatch trial. Participants will complete a MCSP Screening Visit and undergo clinical assessments, laboratory testing, and biomarker analyses to determine preliminary trial eligibility. The study also characterizes clinical, genetic, and biofluid biomarker profiles, assesses the prevalence of ALS-associated gene variants, and banks blood samples for future ALS and biomarker research. MCSP enables simultaneous screening for multiple trial-specific biomarkers and uses a targeted medical history form to optimize matching of participants to appropriate MyMatch trials.

This is a study of Kamlanoflast in patients with ALS. Kamlanoflast is orally administered over 24 weeks. Its effects on inflammatory and functional parameters will be studied. Information on safety and tolerability will be collected.

Amyotrophic lateral sclerosis (ALS) is a relentlessly progressive neurodegenerative disorder characterized by loss of upper and lower motor neurons, leading to muscle weakness, respiratory decline, and eventual mortality. A growing body of translational and clinical evidence implicates neuroinflammation, reactive astrocytosis, and maladaptive TGF-β signaling as central contributors to disease progression. Elevated levels of Gremlin-2 (GREM2) have been identified as a marker of dysregulated TGF-β-linked astrocytic activity and fibrotic gene programs in some ALS patients, and preclinical data suggest that attenuating these pathways may mitigate glial toxicity and improve neuronal survival. Galunisertib, a selective ATP-competitive TGF-β receptor type I (TGF-βR1/ALK5) inhibitor, has been developed to block SMAD2/3 phosphorylation and TGF-β-mediated transcriptional programs. Meanwhile, nerandomilast, a selective PDE4B inhibitor, elevates intracellular cAMP in immune and glial cells, shifting pro-inflammatory signaling toward resolution and antagonizing secondary fibrotic and inflammatory cascades. Preclinical models show that PDE4 inhibition and TGF-β pathway blockade concurrently reduce maladaptive glial phenotypes and fibrotic mediators. This study investigates the combination of galunisertib + nerandomilast in ALS patients with elevated GREM2, hypothesizing that dual targeting of TGF-β-mediated astrocytic reactivity and PDE4B-regulated inflammatory signaling will translate into slowing of disease progression and favorable pharmacodynamic effects on central biomarkers of neuroinflammation and neurodegeneration.

The goal of this clinical trial is to investigate the effect of a muscle-mimicking, fabric-type shoulder orthosis on functional movements of the upper limb in patients with neuromuscular disorder. The main questions it aims to answer are: * What is the impact of the muscle-mimicking, fabric-type shoulder orthosis on upper limb functional movements in patients with neuromuscular disorder? * Are there observable differences in upper limb function when the shoulder orthosis is worn versus when it is not? Participants will: * Receive education on how to wear and use the shoulder orthosis. * Undergo evaluations, including assessment of upper limb performance, shoulder muscle strength testing, active range of motion measurements, assessment of functional workspace, goal attainment scale evaluation, surface electromyography, physiological measurements such as blood pressure and heart rate, fatigue assessment, and assessment for any musculoskeletal or skin-related issues. Researchers will compare neuromuscular disorder patients before and while wearing and operating the shoulder orthosis to see if there are any significant effects on variables such as upper limb function, range of motion, functional workspace, goal attainment scale, and surface electromyography.

The study aims to use 'omics' sciences, employing the most advanced technologies currently available, in order to identify pathogenic genomic variants, proteins and/or altered molecular pathways in neurodegenerative diseases and to obtain a new and more complete characterisation of subjects affected by the neurodegenerative diseases under study. Thanks to the integration of genomic, gene expression (transcriptomic and epigenomic), protein and metabolic data and clinical data, the study also aims to identify new markers for the diagnosis, prognosis, also in terms of response to therapy, and monitoring of neurodegenerative diseases. The study involves the enrolment of at least 1.200 individuals with neurodegenerative disease.

The goal of this study is refine the usability of a BCI capable communication platform. The study will take place in the United States area and will enroll up to 10 participants with late stage ALS, traumatic brain injury (TBI) or spinal cord injury (SCI) that have assistive communication and computer control needs. Each subject will receive an integrated Cognixion + Apple Vision Pro device that includes an augmented reality brain computer interface and associated communication software. The study duration is 3-4 months for each participant. The key questions that will be addressed in this study are: 1. Identify the ability of individuals with target indications to use the integrated Cognixion-Apple Vision Pro system to communicate effectively. 2. Identify the ability of such individuals to learn to use BCI, ET-BCI and other modalities, and to measure their progress over time. 3. Identify the effectiveness of the different forms of input supported by the combined Cognixion-Apple Vision Pro system (BCI, eye-tracking) in allowing such individuals to communicate and have agency. 4. Identify how input such as BCI can be optimized to suit the needs of individuals (e.g., specific frequencies that work best for an individual, SNR with different frequencies, number of targets, length of recording for each frequency) and improve overall usability. 5. Identify the extent to which personalization through a large language model (LLM) affects communication. 6. Identify the appropriate capabilities to enable through an agentic communication interface. Key measures include: ITR - information transfer rate SUS - system usability scale

Motor neuron disease (MND) is a progressive neurological disorder involving degeneration of motor neurons, leading to muscle weakness, speech and swallowing difficulties, and respiratory failure. This study aims to develop a novel treatment approach combining personalized repetitive transcranial magnetic stimulation (rTMS) with mixed reality (MR) exercise-based games (exergames) to slow disease progression and improve quality of life. In this randomised controlled trial study will compare three groups: (1) rTMS with MR exercise (personalized intervention), (2) rTMS with MR exercise (standard intervention), and (3) sham rTMS with MR exercise. Outcomes will be assessed at baseline, 3 months, and 6 months post intervention. The long-term goal is to implement this approach in clinical settings to enhance care for people with MND.

This is a prospective, observational, multicenter registry designed to collect comprehensive clinical, genetic, and outcome data from patients diagnosed with amyotrophic lateral sclerosis (ALS) across Thailand. The registry will establish a national dataset to describe epidemiology, clinical presentation, progression, and treatment outcomes, and will serve as a platform for future clinical and translational research.

The goal of this clinical trial is to learn if drug CB03-154 works to treat ALS in adults. It will also learn about the safety of drug CB03-154. The main questions it aims to answer are: * Does drug CB03-154 have an effect on delaying disease progression, improving function, and prolonging survival in adult ALS patients? * What medical problems do patients have when taking drug CB03-154? Researchers will compare drug CB03-154 to a placebo (a look-alike substance that contains no drug) to see if drug CB03-154 works to treat ALS. Participants (adult ALS patients) will: * Take drug CB03-154 or a placebo every day for 39 weeks (an additional 39 weeks would be required if entering the open-label extension phase). * Visit the clinic approximately every 2-3 months for checkups and tests, and there is also telephone follow-up in between. * Keep a diary of daily medication (CB03-154 or other concomitant medications), and if there are any unplanned medications, the reason (disease or symptoms) also need be recorded.

This study primarily evaluates the safety, tolerability, and efficacy of RAG - 17 in adult ALS patients with SOD1 - mutated genes in the real - world setting.
