Active clinical trials for "Hereditary Sensory and Motor Neuropathy"

This is a 2-year follow-up study of a cohort of 60 CMT1A patients. The objective is to identify markers allowing to better understand the phenotypic variability observed on patients with CMT1A, to identify predictive markers of the disease's progression and to provide validated measurement tools that can be used as outcome measures in future clinical trials.

An observational, non-interventional registry study to collect real-world data from people living with Charcot-Marie-Tooth disease (CMT) and its treatment, which will be available to researchers to further the knowledge of Charcot-Marie-Tooth disease and improve patient care.

Anterior cutaneous nerve entrapment syndrome (ACNES) is caused by nerve entrapment in the abdominal wall. Recently de Weerd and Weum have suggested lumbar cutaneous nerve entrapment syndrome (LUCNES) as a name for a similar condition in the lower back. DIRT can potentially be used to identify the locations of perforators, thereby also indirectly identifying the location of nerve entrapment in ACNES and LUCNES, when a point of maximal pain corresponds to a hot spot. This study evaluates the location of hot spots on DIRT in relation to tender points and perforators visualized with CT angiography and color Doppler. In the ACNES patients, DIRT performed with a low-cost smartphone thermal camera will be compared to DIRT with a professional thermal camera to evaluate the usefulness of low-cost equipment to visualize the point of nerve entrapment.

The purpose of this study is to investigate if a person with weakness or paralysis in one or both arms, can use the NuroSleeve combined powered arm brace (orthosis) and muscle stimulation system to help restore movement in one arm sufficient to perform daily activities. This study could lead to the development of a product that could allow people with arm weakness or arm paralysis to use the NuroSleeve and similar devices to improve arm health and independent function.

This is an observational longitudinal study to determine the natural history and genotype-phenotype correlations of disease causing mutations in Charcot Marie Tooth disease (CMT) type 1B (CMT1B), 2A (CMT2A), 4A (CMT4A), and 4C (CMT4C). The investigators will also be determine the capability of the newly developed CMT Pediatric Scale (CMT Peds scale) and the Minimal Dataset to measure impairment and perform longitudinal measurements in patients with multiple forms of CMT over a five year window

This study will assess the serum NT-3 levels in individuals with the diagnosis of peripheral neuropathy or any type of Charcot-Marie-Tooth Neuropathy (CMT) and correlate this with function.

Charcot-Marie-Tooth disease (CMT) is a group of the most common hereditary peripheral neuropathy with high clinical and genetic heterogeneity. Biallelic pathogenic variants in SORD gene leading to loss of function of SORD protein cause axonal degeneration. Current research suggests that SORD-CMT2 may be the most common subtype of AR-CMT2. The primary purpose of this study is to explore the natural history of SORD-CMT2 patients by detecting the ONLS scale score and serum sorbitol level changes at 6th, 12th, 24th, and 36th months and to evaluate the effectiveness and safety of epalrestat. Patients with strong treatment willingness and voluntary purchase of drugs are included in the epalrestat treatment group, and patients without drug treatment willingness are included in the control group. Patients in the drug treatment group take epalrestat (50 mg) orally three times daily. This study is expected to be carried out simultaneously in 5 hospitals in mainland China. About 30 SORD-CMT2 patients will be enrolled in this study, and the study period will be 36 months.

Charcot-Marie-Tooth (CMT) disease is the commonest sensitivo-motor inherited peripheral neuropathies with a prevalence of about 10-30 per 100,000. To date, more than 80 genes have been found responsible for CMT. Some of these genes code for mitochondrial proteins such as mitofusin 2 (MFN2). In the last few years, our laboratory has developed strong expertise in metabolomics. The MetaDLM_CMT2A project proposes to produce metabolomic and lipidomic maps in CMT2A plasma from a cohort of genetically and clinically characterized patients with a national recruitment. In the perspective of future clinical trials, these biomarkers and the better understanding of lipid metabolism defects in CMT2A would be of major interest in monitoring the evolution of the disease and developing specific therapeutic approaches.

The goal of this study is to establish a genetic registry of patients with early-onset motor neuron and neuromuscular diseases. The investigators will collect samples from patients with a motor neuron or a neuromuscular disorder and their family members. The samples to be collected will be obtained using minimally invasive (whole blood) means. The research team will then extract high quality genomic DNA or RNA from these samples and use it to identify and confirm novel gene mutations and to identify genes which regulate the severity of motor neuron/neuromuscular diseases.

This clinical trial is an open-label one-time injection dose study in which scAAV1.tMCK.NTF3 will be administered by intramuscular injections into muscles in both legs in CMT1A subjects with PMP22 gene duplication. Three subjects ages 18 to 35 years receiving (8.87e11 vg/kg) will be enrolled.
