Filter by:Spinal muscular atrophy (SMA) is a form of motor neuron disease, most commonly caused by a mutation in the survival motor neuron 1 gene (SMN1) which results in a wide disease spectrum affecting children and adults. It is an autosomal recessive disorder and is therefore caused by inheritance of a mutated gene from each parent. All forms of SMA have an estimated combined incidence of 1 in 6,000 to 1 in 10,000 live births, with a carrier frequency of 1/40 to 1/60. The patient registry aims to facilitate a questionnaire-based research study in order to better characterise and understand the disease in the UK and in Ireland. Entry is via self-registration over a secure internet connection (https://www.sma-registry.org.uk/). Online, patients are asked to read an information sheet about the research project and then indicate their consent to demonstrate willingness to participate. Following online consent, subjects will be entered into the registry. This is an on-going database and all participants are invited to update their information on a biannual basis.
The primary objectives of the study are to assess the safety, tolerability and evidence of activity of 12 months oral treatment with TEFIDERA® in subjects with Geographic Atrophy associated with Age-Related Macular Degeneration (AMD).
This study aims to refine the capability of Multispectral Optoacoustic Tomography (MSOT) and Magnet Resonance Imaging (MRI) to characterise the molecular composition of muscle tissue non-invasively and to evaluate the therapeutic response in patients with spinal muscular atrophy (SMA) over time.
Multiple system atrophy (MSA) is a rare and fatal neurodegenerative disorder. The pathologic hallmark is the accumulation of aggregated alpha-synuclein in oligodendrocytes forming glial cytoplasmic inclusions. Some symptomatic treatments are available while disease-modification remains an unmet treatment need. Post-mortem findings suggest insulin resistance, i.e. reduced insulin signaling, in the brains of MSA patients. The aim of this study is to complete the target validation of insulin resistance for future treatment trials.
Patients lose a significant amount of muscle following major abdominal surgery. This is partly due to a catabolic response to the surgical insult and inflammation, but is also probably due to a lack of muscle use secondary to immobility. This study will aim to assess whether some or even all of postoperative muscle loss in the upper leg muscle group is preventable through electrical muscle stimulation to mimic physical activity.
Loss of muscle can be caused by a variety of stimuli and results in reduced mobility and strength and also impacts whole body health. Whilst it is known that muscles waste the process by which this occurs is not well understood. Furthermore, whilst some muscles waste quickly others seem resistant to the effects of disuse. This study aims to evaluate how quickly changes in muscles start to occur, and investigate the processes which underlie muscle atrophy. By studying muscles which waste quickly and those which are resistant to atrophy this study aims to identify the different processes which lead to muscle loss. This study will also evaluate the differences in muscle changes between young and old people.
This is a multi-center prospective case control study aiming to compare different methods of risk stratification models in predicting the risk of gastric cancer development.
The primary objectives of the study are to obtain clinically meaningful data on survival and outcomes of all the patients with spinal muscular atrophy (SMA) 5q types 1 through 4 (according to international classification), being followed in the reference centers of the disease in France between September 1, 2016 and August 31, 2024. The registry will collect retrospectively and prospectively the longitudinal data of the long-term follow-up for child and adult patients, under real life conditions of current medical practice, in order to document the clinical evolution of patients (survival, motor, respiratory, orthopedic and nutritional), the conditions of use of the treatments, the mortality rates of treated and untreated patients, the tolerance of the treatments, adverse events in order to better define their places in the therapeutic strategy.
Spinal muscular atrophy (SMA) is a neurogenetic disorder caused by a loss or mutation in the survival motor neuron 1 gene (SMN1) on chromosome 5q13, which leads to reduced SMN protein levels and a selective dysfunction of motor neurons. SMA is an autosomal recessive, early childhood disease with an incidence of 1:10,000 live births. SMA is the leading cause of infant mortality due to genetic diseases. Until recently, the mainstay of treatment for these patients was supportive medical care. However, advances in medical treatment focusing on gene replacement, gene enhancement, motor neuron protection and muscle enhancement is likely to change the management and prognosis of these patients in the future. The purpose of this registry is to assess the long term outcomes of patients with SMA in the context of advances in treatment options.
The primary objectives are to evaluate the safety and tolerability of multiple doses of ION464 administered via intrathecal (IT) injection (Part 1) and to evaluate the long-term safety and tolerability of ION464 (Part 2) in participants with multiple system atrophy (MSA). The secondary objectives are to evaluate the pharmacodynamic (PD) effect of ION464 on the level of a potential biomarker of target engagement (Parts 1 and 2) and to evaluate the pharmacokinetic (PK) profile of ION464 in serum (Part 1).
