Filter by:A Phase 3 Randomized, Double-Blind, Placebo-Controlled, Global Study to Evaluate the Efficacy and Safety of Intravenous Delpacibart Etedesiran (abbreviated del-desiran, formerly AOC 1001) for the Treatment of Myotonic Dystrophy Type 1
The rationale of the study is to collect structured data in the neuropsychological, clinical neuroradiologic and neurorehabilitation fields in children/young people affected by congenital and juvenile myotonic dystrophy. Children affected by the congenital form (CDM1) present important brain alterations present since birth while, on the contrary, patients with the adult form of DM1 often present a degenerative, slowly progressive neurocognitive picture. Promising therapies that aim to correct the molecular mechanism underlying the symptoms of adult forms of DM1 are under development, but their potential role at the level of the nervous system and in particular in forms of CDM1 (which appears to be a distinct disorder of neuronal development) is also to be clarified. To this end, a better definition of neurocognitive profiles and their evolution is essential for the purposes of evaluating the effectiveness of experimental therapies.
The goal of this clinical trial is to test ATX-01 in participants with myotonic dystrophy type 1 (DM1). The main question it aims to answer is if ATX-01 is safe and well tolerated. The trial will compare the safety and tolerability of ATX-01 and a matching placebo. There will be a single-ascending dose part of the trial and a multiple-ascending dose part. In the single-ascending dose, participants will receive one dose of ATX-01 or placebo. In the multiple-ascending dose part, participants will receive three doses of ATX-01 or placebo. ATX-01 is a novel anti-miR (synthetic single stranded oligonucleotide) that inhibits a microRNA called miR-23b.
Type 1 myotonic dystrophy (MD1) is a genetic and hereditary disease that primarily affects muscle tissue, resulting in myotonia (difficulty relaxing after contraction) and atrophy (progressive muscle weakening with decreased muscle volume). It also affects eyes, heart, endocrine system, gastrointestinal system and central nervous system. Specific cognitive abilities are impaired in patients with MD1 such as attention, visio-spatial or visio-building abilities as well as executive dysfunctions. Currently, the cognitive assessment of MD1 patients is based on classical neuropsychological tests, which are time-consuming and require a MD1 expert neuropsychologist. Moreover, it is usually very difficult for MD1 patients to accept performing these tests, and when they agree to perform them, they usually give up before the end. This finding is more frequent in MD1 patients with high level of cognitive impairment. In order to overcome these difficulties in assessing cognitive functions of MD1 patients, the investigators decided to use innovative tools such as virtual reality, which allow individuals to experience a sensory-motor and cognitive experience in a digitally world through a helmet, glasses and joysticks. The start-up My Cyber Royaume from Lille, in collaboration with the reference center of neuromuscular diseases from Nice coordinated by Pr Sacconi, have developed a software "Good Diag NMD" which uses virtual reality to assess cognitive disorders, more specifically executive functions in patients with type 1 myotonic dystrophy.
The primary purpose of the study is to evaluate the safety and tolerability of single intravenous (IV) doses of PGN-EDODM1 administered to participants with Myotonic Dystrophy Type 1 (DM1). The study consists of 2 periods: A Screening Period (up to 30 days) and a Treatment and Observation Period (16 weeks).
This is a Phase 1/2a double-blinded, placebo-controlled, dose-escalating study to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of single and multiple ascending doses of ARO-DM1 compared to placebo in male and female subjects with Type 1 Myotonic Dystrophy (DM1). Participants who have provided written informed consent and met all protocol eligibility requirements will be randomized to receive single (Part 1) or multiple (Part 2) doses of ARO-DM1 or placebo.
Myotonic dystrophy 1 (DM1) is an autosomal, dominantly inherited neuromuscular disorder characterized by skeletal muscle weakness, myotonia, cardiac conduction abnormalities, cataracts, and other abnormalities. This disease results from an expansion of a cytosine-thymine-guanine (CTG) trinucleotide repeat in the 3'-untranslated region of the dystrophia myotonica protein kinase (DMPK) gene on chromosome 19. Currently, there is limited phenotype and genotype data available for DM1 patients with Chinese Han ethnicity. Therefore, this study aims to fill this gap and provide complementary data.
The goal of this observational study is to assess movement in individuals with Myotonic Dystrophy Type 1 (DM1) and Type 2 (DM2) using digital biomarker tools. The long-term aim of this study is to incorporate these outcomes into clinical trials of DM1 and DM2 therapies. Participants will complete a series of assessments that allow for researchers to measure hand myotonia and walking quality, including a Video Hand Opening Test (VHOT), grip strength, 10 meter walk/run test, 6 minute walk test, Timed Up and Go (TUG), Motor Function Measures-32 (MFM-32) test, and more. These assessments may be recorded to detect and map participants motion and walking patterns. Several patient reported outcome (PROs) questionnaires will also be recorded. Participants may also be asked to monitor exercise and sleep activity at home using an Actigraph wearable device. This study is divided into 2 parts: Part A consists of a single visit. Part B consists of a 1-year longitudinal study with 3 clinical follow-up visits.
The objective of the ActiLiège Next study is to collect longitudinal data from patients and control subjects using a wearable magneto-inertial device. By collecting natural history data in various neuromuscular disorders (Duchenne Muscular Dystrophy, Fascioscapulohumeral Muscular Dystrophy, Myotonic Dystrophy 1, Charcot-Marie-Tooth, Centronuclear Myopathy, Congenital Muscular Dystrophy), we aim to validate digital outcome measures to continuously assess motor function in real-life.
The goal of this observational study is to learn about swallowing difficulties (dysphagia) in patients living with myotonic dystrophy type 1 (DM1). The main questions it aims to answer are: - whether the size and structure of the muscles involved in swallowing differ to those without the disease - how the size and structure of muscles may associate with swallowing function and swallowing symptoms in this group. Participants will undergo a range of tests including: - Ultrasound (US) assessment of the muscles involved in swallowing - An x-ray swallowing study (known as videofluoroscopy) - Assessment of swallowing symptoms, including questionnaires - Assessments of mobility, activity and breathing - Assessments of quality of life and wellbeing
