Filter by:Phase II/III multicenter, randomized, double-blind, placebo-controlled trial on acetyl-L-carnitine (ALCAR) in subjects living with amyotrophic lateral sclerosis (ALS). Primary study aim: The clinical objective consists of assessing the efficacy of ALCAR (two different dosages will be tested: 1.5g/day and 3g/day) on the progression of functional disability (loss of self-sufficiency), as measured by the ALSFRS-R scale. Secondary study aims: 1. The effect of ALCAR treatment on different clinical aspects: functional decline as measured by ALSFRS-R total score; the decline of forced vital capacity (FVC); quality of life as measured by ALSAQ-40 scale; cognitive function as measured by Edinburgh Cognitive and Behavioural ALS Screen (ECAS) scale; survival (being alive and without tracheostomy). 2. To measure the effects of ALCAR treatment on disease biomarkers potentially involved in the drug's mechanisms of action. These include PGC-1 alpha, 3-nitrotyrosine (3-NT), acetyl cyclophilin A (acetyl-PPIA), neurofilament light chain (NFL), creatine kinase (CK), Musclin/osteocrin, MyomiRNA (MiR-206), Uric acid, Matrix metalloproteinase-9 (MMP-9), Monocyte Chemoattractant Protein-1 (MCP-1), 4-Hydroxynonenal (HNE). 3. The tolerability and safety of ALCAR treatment by identifying unexpected adverse events. Study population: 246 subjects will be enrolled on one Australian and ten Italian ALS sites. Inclusion criteria: subjects aged 18+ years with a diagnosis of ALS according to Gold Coast Criteria; disease duration <24 months; satisfactory bulbar and spinal function (self-sufficiency evaluated by a score 3+ on the ALSFRS-R for swallowing, cutting food and handling utensils, and walking); satisfactory respiratory function (FVC ≥80% of predicted); documented progression of symptoms as measured by the ALSFRS-R scale. Disease progression rate (DFS) must be>= 0.33. DFS =(48- ALSFRS-R at screening)/months from onset to screening, treatment with Riluzole in the last four weeks. Exclusion criteria: antecedent polio infection; other motor neuron disease; involvement of other systems possibly determining a functional impairment; other severe clinical conditions; unwillingness or inability to take riluzole; previous use of ALCAR for any reason; inability to understand and comply with the study requirements, and to give written informed consent personally or via their legally authorized representative. All eligible participants will be randomized to receive ALCAR (1,5 or 3 g/day) or placebo in addition to riluzole 50 mg b.i.d. Permuted block (with a block size of 6), 1:1:1 centralized randomization scheme will be used. The overall treatment duration will be 48 weeks. After enrolment, each participant will be followed up until death. Eligible subjects will be seen after 4, 12, 24, 36 and 48 weeks. At each visit, a general assessment will be made, including vital signs, body mass index (BMI), neurological examination (including quantitative and qualitative evaluation of the motor system), comorbidity, concomitant treatments and adverse events. Blood samples will be collected at baseline -Day 1 (randomization)-, 4, 12, 24, 36 and 48 weeks to test biomarkers. Functional disability will be assessed at each visit using the ALS-FRS-R scale. The respiratory function will be assessed using a spirometer to measure FVC before starting treatment (baseline visit) and at 4, 12, 24, 36 and 48 weeks. Cognitive function will be evaluated at baseline, weeks 24 and 48, using ECAS scale. Health-related quality of life, measured by the ALSAQ-40, will be tested at baseline, 24 and 48 weeks. Compliance will be tested by the local investigators, counting unused packages at each follow-up visit. Pre-planned statistical analyses will be done on Intention-to-treat and Per-protocol (PP) populations. The statistical plan will include descriptive statistics and a comparison of the proportions of self-sufficient participants at week 48 using the chi-square or Fisher's exact test for the primary endpoint. Secondary endpoints measured by numerical scores obtained from clinical scales will be analyzed using repeated measures mixed models, while biomarkers using repeated measures ANOVA. Time-to-event endpoints, such as survival and the probability of remaining self-sufficient over 48 weeks, will be analyzed with Kaplan-Meier curves. The number of adverse events and serious adverse events after 48 weeks will be compared between treatment arms.
The goal of this clinical trial is to learn how doing mechanical insufflation (MI) using a mechanical insufflator-exsufflator (MI-E) device affects breathing in early amyotrophic lateral sclerosis (ALS). This will be a single-center, single-arm study of MI in 20 patients with ALS at Penn. Based on prior research, we believe that 6-months of MI may slow decline in cough strength, measured as peak cough flow (PCF). Participants will perform MI using a device designed for mechanical insufflation-exsufflation (MI-E) known as the BiWaze Cough system. The BiWaze Cough is used for mucus clearance . It is connected to tubing and mouthpiece (or mask). The device will use programmed pressure and timing settings. An insufflation includes inflating the lungs for a maximal size inhalation before exhaling. The daily routine for the device includes 5 sets of 5 insufflations twice daily. Researchers will compare how use of MI in early ALS affects peak cough flow compared to 20 subjects who did not use MI in early ALS.
This is the study of AMT-162 in Participants with SOD1-ALS and is designed to evaluate the safety, tolerability, and exploratory efficacy of intrathecally administered gene therapy AMT-162. AMT-162-001 is a Phase 1/2, multi-center, single ascending dose study.
The goal of this study is to improve our understanding of speech production, and to translate this into medical devices called intracortical brain-computer interfaces (iBCIs) that will enable people who have lost the ability to speak fluently to communicate via a computer just by trying to speak.
The Earswitch is a demonstrated proof-of-concept that detects the voluntary contraction of a small muscle in the ear, called the tensor tympani (TT) muscle, which can be effectively used as an input switch. The voluntary activation of the TT makes the eardrum move, and such movement can be detected using a small camera inserted into the ear canal. A previously funded NIHR 'i4i Connect' research project showed how the Earswitch may be advantageous to populations with severe neuro-disabilities, where other communication methods are limited. This project aims to realise the EarSwitch's potential as an assistive communication device and provide supporting evidence towards regulatory approval of the medical device. The robustness and usability of the device will be tested on participants with mild-to-moderate neuro-disabilities and healthy participants. This complements data collected from assistive technology users following the same protocol but will provide additional data to train and understand the underlying detection algorithms for the Earswitch. The ease of which an assistive technology device can be installed and calibrated independently (without guidance from the researcher) so that it is ready to use is also an important consideration for its potential adoption. Participants will have the opportunity to interactively use the Earswitch daily at home, over a prolonged period of 4 weeks. Interviews and questionnaires will be used to gather information on usability and comfort of the device, whilst data from the interactive tasks will provide feedback of engagement and performance. Overall, this will provide crucial insights into how viable the Earswitch is as an assistive technology device and how accurately and reliably the current detection algorithm can detect contraction of the TT muscle. This data will be analysed to inform the final design of the Earswitch ready for commercial production.
Genetic diagnosis of Amyotrophic Lateral Sclerosis (ALS) could identify the origin of the disease, potentially allowing the patient to pursue targeted/gene therapy. However, many familial forms of ALS are genetically undiagnosed, either because no variant has been detected in the genes of interest, or because the detected variant(s) have uncertain significance. Currently, molecular diagnosis takes place in two stages: 1) Search for the GGGGCC expansion in the C9ORF72 gene by RP-PCR; 2) Analysis of the coding regions by high-throughput sequencing of a panel of 30 genes involved in ALS. Many of these variants of uncertain significance affect splicing. Their impact can be predicted using in silico tools, but only an analysis of the patient's RNA can confirm their pathogenic nature. Currently, the analysis of transcripts is only done a posteriori, when a variant predicted to impact splicing is detected on the patient's DNA. RT-PCR followed by Sanger sequencing then verifies the impact of the splice variants. This method confirmed the impact of certain splice variants in patients. However, this method is time-consuming and requires custom development, and is mutation/gene/patient-dependent. In contrast, high-throughput RNA sequencing (RNA-Seq) simultaneously analyzes the splicing of numerous genes, with a global approach, applicable to all patients. This approach avoids the custom design of primers, which can be biased by the interpretation of splicing predictions, while RNA-Seq systematically captures and sequences all the transcripts. Finally, RNA-Seq provides additional information compared to DNA sequencing such as the detection of exon skipping, intron inclusion, and the creation of fusion transcripts. In the GTEx project (GTEx Consortium, 2013), expression levels of human genome transcripts were quantified by RNA-Seq. Using these results, the study investigators measured expression of transcripts of known ALS genes in whole blood. Applying a threshold value of 0.5 transcripts per million reads (TPM), 25 of the 30 ALS genes currently analyzed by NGS in routine diagnostics at Nîmes University Hospital could be eligible for a complete analysis by RNA-Seq. None of the French laboratories carrying out genetic analyzes of ALS has yet developed RNA-Seq as a routine diagnostic tool. The study laboratory receives more than 600 requests for genetic diagnosis of ALS patients per year. The aim of this study is therefore to develop a global method for analyzing RNA transcripts of ALS genes to categorize the mutations to improve the diagnostic management of patients.
Psychological distress (anxiety and depression) is common in and experienced differently by people living with long-term health conditions (LTCs). Being able to measure whether psychological distress is related to living with a LTC would allow researchers and clinicians to provide interventions specifically tailored to the challenges of living with a LTC and therefore provide the most appropriate support for these patients. Such a measure would also be useful in research to identify the presence of illness-related distress in different patient groups. This project will therefore create a new measure of illness-related distress that has applications for both research and clinical practice. This will involve the psychometric validation of the new illness-related distress measure to test how valid and reliable the measure is. The aim of the project is to provide initial validation of the Illness Related Distress Scale in a community sample, recruited through online platforms. The objective of the study is to gather initial validity and reliability data for the scale.
This EAP will provide access to pridopidine for up to 200 patients with ALS who are ineligible for clinical trials. Pridopidine will be given at a dose of 45 mg twice daily p.o. (or via feeding tube). Each patient will be followed for 2 years with regularly scheduled visits. The screening and baseline visits will be performed in person; subsequent visits may occur in person or remotely. Recommended in-person visits will occur at Weeks 12, 52, 78, and end of treatment (Week 104 or early termination). If the patient is unable to complete the visits in person, these visits may also be completed remotely.
The goal of this observational study is the develop new ways of remotely monitoring the health and symptoms of people living with amyotrophic lateral sclerosis from within their homes. The main questions it aims to answer are: - Can we integrate a new muscle monitoring device into Imperial College London's home monitoring platform? - Can we investigate and understand the relationship between muscle activity and measure of patient behaviour (e.g., patient movement), physiology (e.g., pulse/blood pressure variation) and sleep quality from the home? - Can we establish a home-based multimodal biomarker that tracks the neurodegenerative process in ALS? Participants will have passive internet-of-things sensors and internet-enabled medical devices installed in their homes for one year. Some sensors will record automatically without any interaction from the participants, but some will require participants to engage with daily (e.g., blood pressure monitor) on their own or with the help of a study partner. Where possible, researchers will compare the collected data to other neurodegenerative diseases and healthy controls to understand differences over time.
The evolution of amyotrophic lateral sclerosis (ALS) is marked by dyspnea, anxiety and pain, major determinants of suffering induced by this disease. The only palliative treatment for respiratory failure is non-invasive ventilation (NIV), which compensates failing respiratory muscles and relieves dyspnea, improves quality of life and increases life expectancy. In ALS patients, the persistence of dyspnea outside of NIV sessions has highlighted the need for therapeutic alternatives in the treatment of persistent dyspnea, including immersive virtual reality (IVR) and auditory distraction through music (music therapy). This study evaluates the effect of IVR on respiratory discomfort in ALS patients with persistent dyspnea treated with NIV.
