Adults With SMA Treated With Nusinersen

Spinal Muscular Atrophy

This is a single center, 22-month observational study of nusinersen treatment in adult patients with spinal muscular atrophy (SMA). There will be a total of seven visits. Nusinersen is provided as standard of care and not considered research in this study. Information will be collected regarding the general health, and function including muscle strength of, as well as any positive and/or adverse events experienced by the study participants.

Mechanisms of Cell Death in Spinal Muscular Atrophy

Spinal Muscular Atrophy

Spinal muscular atrophy is a genetically based disease that affects motor neurons in the spinal cord and leads to muscle wasting and weakness. The gene found to be responsible for the underlying disease is called the SMN or survival motor neuron gene. Individuals with SMA are either missing a copy of the gene or have a mutation in the gene. Although the gene has been identified, how it actually causes the motor neurons to die and leads to muscle wasting and weakness is not completely understood. The investigators have found that skin cells from children with SMA tend to be more susceptible to cell death when exposed to cell death inducing agents. In this protocol, The investigators wish to study the mechanisms by which these cells die when exposed to these agents and how this may be related to the gene defect and the disease.

Ability of Muscle Imaging and Motor Function Measure (MFM) to Detect Changes in Disease Progression...

Healthy VolunteerMuscular Atrophy1 more

This non-drug, single center, 24-week, longitudinal study in ambulant spinal muscular atrophy (SMA) patients and in age- and gender-matched healthy volunteers will assess the detection of disease progression by magnetic resonance imaging (MRI) and the Muscle Function Measure (MFM) test. Each participant will be evaluated in three testing sessions: at baseline, at Week 12 and at Week 24. Both patients and volunteers will undergo MRI scans. Patients will additionally undergo testing of motor function and have blood samples taken for Survival of the Motor Neuron (SMN) genes, proteins and mRNA analysis.

Prospective Study of the Natural History of Patients With Type 2 and 3 Spinal Muscular Atrophy

Type 2 Spinal Muscular AtrophyType 3 Spinal Muscular Atrophy

NatHis-SMA is a prospective, longitudinal and interventional study of the natural history of patients with type 2 and 3 Spinal Muscular Atrophy (SMA). The purpose of this study is to characterize the disease course over 2 years and identify prognostic variables of the disease and biomarkers of SMA progression, as well as determine the best outcome measures for further therapeutics approaches.

SMN Copy Number Distribution in Mali, West Africa

Spinal Muscular Atrophy

Background: Spinal muscular atrophy (SMA) is a degenerative and incurable neuromuscular disorder that is caused by mutations in the survival motor neuron gene, SMN1, found on chromosome 5. It is the leading inherited cause of infant mortality. SMA carriers (those who have the genetic mutation but do not have the disease) are often unaware of their status until they are tested. Researchers have been studying the prevalence of SMA carriers in the general population, but most of the information collected has come from populations within the United States, Europe, and Asia. Very few studies have been performed in Africa. Furthermore, this information does not provide much information regarding carrier frequency based on ethnic background and ancestry. To address this problem, researchers are interested in studying the prevalence of the SMA genetic mutation in the sub-Saharan nation of Mali. Objectives: - To collect blood samples for use in studying genetic data related to spinal muscular atrophy. Eligibility: Healthy volunteers who are at least 18 years of age. Volunteers will be of Malian ancestry and nationality. Study Location: -<TAB>Bamako, Mali, West Africa Design: The study will first collect blood samples from a small group of volunteers to run initial SMA carrier testing and resolve any technical difficulties before continuing with the study. Participants will complete questionnaires about their personal and family medical history, including questions about illnesses, stillborns, and miscarriages, and then will provide blood samples for genetic research and testing.

A Pilot Study of Biomarkers for Spinal Muscular Atrophy

Spinal Muscular Atrophy

The goal of this pilot study is to identify a marker or panel of markers in the blood or urine from a wide range of Spinal Muscular Atrophy (SMA) patients that segregates with measures of clinical severity. From this identification of candidate biomarkers, it is hoped that further investigations, both longitudinal natural history and clinical efficacy studies, will verify a biomarker with the sensitivity and specificity that will allow its eventual use as a validated pharmacodynamic marker or surrogate endpoint. In addition, this effort may elucidate biological pathways that may be potential therapeutic targets.

Ultrasound-assisted or Landmark-based Intrathecal Administration of Nusinersen in Adult Patients...

AnesthesiaSpinal3 more

Nusinersen (Spinraza, Biogen Inc, Boston, MA), the first treatment approved by FDA and EMA for all Spinal Muscular Atrophy (SMA) subtypes, is an antisense oligonucleotide that is administered intrathecally through a lumbar puncture. This procedure can be challenging in some adults with intermediate and late onset SMA (types II-IV) frequently presenting scoliosis secondary to neuromuscular weakness and often treated with spinal instrumentation to prevent worsening deformities. In such patients, in order to access the intrathecal space, US guidance and/or assistance have been recently proposed as useful and successful tool. The US guidance and/or assistance have been associated to a high success rate, a reduction of number of attempts and needle passes to obtain a successful anesthesia. A reduced risk of adverse events (AEs), such as post dural puncture headache (PDPH) and low back pain (LBP), and low patient satisfaction often associated with multiple needle punctures was also reported. Aim of this retrospective study was to report the efficacy, evaluated as rate of the successful procedures and subsequent delivery of nusinersen within the subarachnoid space, the number of attempts, the procedure time and the adverse events (AEs) of interlaminar intrathecal nusinersen administration using either ultrasound assistance or the landmark-based technique in a historical cohort of 51 adult SMA patients.

Clinical Assessment of Spinal Muscular Atrophy Type II and III (SMA Europe)

Spinal Muscular Atrophy

The aim of this project is to establish a network of clinical teams including the major neuromuscular centers in Europe. We plan to work together to find the best common outcome measures for the following multicenter therapeutic trials.

Spinal Muscular Atrophy (SMA) Biomarkers Study in the Immediate Postnatal Period of Development...

Spinal Muscular Atrophy (SMA)

Spinal muscular atrophy (SMA) is the leading genetic cause of death of infants. Strong preclinical evidence suggests that effective therapy must be delivered as early as possible to prevent progression of the disease. The primary study objective will be to identify prognostic and surrogate biomarkers of disease progression that will facilitate the execution of therapeutic SMA clinical trials in infants.
