Filter by:Until twenty years ago physical exercise in muscular dystrophies was considered harmful to the muscle cells, inducing an acceleration of cell necrosis. In fact, it is now certain and validated that an active lifestyle and the practice of controlled and regular physical activity are to be considered therapeutic in neuromuscular pathologies with the aim of optimizing muscular and cardio-respiratory function and preventing atrophy In particular, it seems that the optimal care is extensive and can be carried out in a safe and controlled manner even at home. It is well documented that exercise has beneficial effects on muscle with increased strength and muscular endurance.
The aims of the study are to prospectively collect information on several aspects of function in non-ambulant DMD patients by using a structured battery of tests including motor, respiratory and cardiac function
To characterize the clinical phenotype and possible predictive/prognostic factors of patients with Duchenne muscular dystrophy (DMD) due to duplication of exon 2 (Dup2). Specifically, we aim 1) to describe the progression of motor, respiratory and cardiac function; 2) to enquire if the phenotypic spectrum of Dup2 is milder than classic DMD, 3) to perform whole genome sequencing (WGS) to characterize DNA breakpoints to correlate with the phenotype; 4) to collect material for future proteomic/transcriptomic studies. Background/Rationale DMD is caused by mutations in the DMD gene and in 11% of cases is due to duplications. The most promising therapeutic approaches include mutation-specific therapies. Notably, there is increasing evidence that specific groups of mutations may underlie different disease trajectories compared to the "average" DMD population. It is thus mandatory to have more information on genotype-phenotype correlations and patterns of progression related to different genotypes. Dup2 is the most common DMD duplication and the only one for which a AAV-mediated exon skipping study is ongoing. Despite most case series and databases ascribe Dup2 to severe phenotype, our preliminary findings sustain that these patients have collectively a milder progression of the disease and in 1/3 of cases a significantly milder phenotype. Moreover, our attempts to reveal mechanism involved in attenuating the phenotype would confute the hypothesis of alternative spicing transcripts as previously described for DMD with deletion of exon 2. Research design and methods Clinical information regarding a cohort of 26 Italian Dup2 patients will be collected. Differences in time to loss of ambulation compared to a DMD control group will be achieved. Finally, we will retrieve DNA for correlative WGS studies. Anticipated output We expect that Dup2 patients present a milder DMD phenotype , which might be predicted by genomic studies.
The purpose of this study is to test the safety and tolerability of BMN 351 in participants with Duchenne Muscular Dystrophy (DMD) with a genetic mutation amenable to exon 51 skipping.
This is a multicenter, prospective, observational Phase 4 study in the United States. The study is designed to collect both medical history and prospective data on Duchenne muscular dystrophy (DMD) treatment outcomes in participants receiving delandistrogene moxeparvovec as part of clinical care, compared to participants with DMD receiving or prescribed to start chronic glucocorticoid treatment at baseline in routine clinical practice. In addition, treatment outcomes will be collected prospectively from post-trial participants who have received delandistrogene moxeparvovec through participation in select SRP-9001 studies.
This is a multicenter, global study of the effects of a single systemic dose of SRP-9003 on beta-sarcoglycan (β-SG) gene expression in participants with limb-girdle muscular dystrophy, type 2E/R4 (LGMD2E/R4). This study will consist of both ambulatory participants (Cohort 1) and non-ambulatory participants (Cohort 2).
Facioscapulohumeral dystrophy (FSHD) is one of the most common hereditary neuromuscular disorders (NMD), with an estimated prevalence of 2000 patients in the Netherlands. Magnetic resonance imaging (MRI) and muscle ultrasound have contributed to an enhanced understanding of the pathophysiology of Facioscapulohumeral Muscular Dystrophy (FSHD). Previously, our group demonstrated the potential presence of an intermediate factor between muscle fiber loss and clinical weakness in FSHD. The influence of disrupted muscle architecture in FSHD on muscle contractile efficiency is a likely candidate for this factor, and remains relatively unexplored. In this study, we aim to assess the use of ultrasound-defined contractile performance, in comparison with current measures including structural MRI, for monitoring disease progression in FSHD.
Facioscapulohumeral muscular dystrophy (FSHD) is characterized by clinical diversity, with FSHD1 being the most common form. It is associated with a toxic gain of function of the Double homeobox 4 (DUX4) gene, leading to muscle cell death and weakness. Despite the lack of approved treatments, recent studies highlight inflammation's role in early FSHD progression, triggered by inappropriate DUX4 expression. In understanding inflammation's pivotal role in FSHD, a study assessed serum cytokines in 100 adult FSHD1 patients. Out of the 20 cytokines examined, 10 showed significantly altered expression levels compared to healthy controls of similar age and sex. FSHD1 patients exhibited heightened levels of inflammatory cytokines and diminished anti-inflammatory cytokines, signaling chronic inflammation. Notably, Interleukin-6 (IL-6) emerged as a promising disease activity biomarker, displaying robust correlations with established clinical severity and functional scores. Given the pathological significance of inflammation and the correlation of IL-6 levels with disease severity, the ReInForce study will explore the satralizumab, an IL6-receptor (IL6-R) antagonist, for its efficacy in specifically reducing muscle and systemic inflammation. By antagonizing IL-6R downstream signaling, satralizumab holds promise in mitigating inflammation and potentially curtailing fibrofatty degeneration in FSHD.
Subjects who have enrolled in the oculopharyngeal muscular dystrophy (OPMD) natural history study (Study BNTC-OPMD-NH-001) and have completed at least 6 months of follow up in Study BNTC-OPMD-NH-001 may be eligible to participate in this study, where all subjects will be treated with a single dose of BB-301. BB-301 will be injected directly into the middle pharyngeal constrictor muscle and the inferior pharyngeal constrictor muscle of the throat through the use of an open surgical procedure conducted under general anesthesia. The primary objectives of the study are to evaluate the safety of BB-301, to identify the best dose of BB-301 to administer to patients, and to characterize how well BB-301 works to improve the symptoms of dysphagia in patients with OPMD.
This is a multicenter, open-label, non-randomized study to investigate the safety, tolerability, and efficacy of a single IV infusion of SGT-003 in participants with Duchenne muscular dystrophy. There will be 2 cohorts in this study, dosed sequentially. Cohort 1 will include participants 4 to <6 years of age, inclusive. Cohort 2 will only be opened after dosing and monitoring a subset of participants in Cohort 1. Cohort 2 will include participants 6 to <8 years of age, inclusive. All participants will receive SGT-003 and will be enrolled in the study for 5 total years for long-term follow up.
