Risdiplam works by helping the body produce more survival motor neuron (SMN) protein throughout the body. This means fewer motor neurons - nerve cells that pass impulses from nerves to muscles to cause movement - are lost, which may improve how well muscles work in people with SMA. RO7204239 is an investigational anti-myostatin antibody that is designed to target myostatin. Myostatin plays an important role in the regulation of skeletal muscle size by controlling growth. Inhibiting myostatin may help muscles grow in size and strength. RO7204239 in combination with risdiplam, which is designed to increase the amount of SMN protein throughout the body, has the potential to further improve motor function and clinical outcomes for people living with SMA. This trial will study the safety and efficacy of RO7204239 in combination with risdiplam in patients with spinal muscular atrophy (SMA). The trial has two parts; Part 1 is the dose-finding part in SMA patients that are either ambulant (aged 2-10 years) or non-ambulant (aged 5-10 years) within separate cohorts, and Part 2 is the pivotal part in SMA patients aged 2-25 years that are ambulant.
NCT07444476
In this study, researchers will learn more about the effects and safety of BIIB115, also known as salanersen. Specifically, researchers will learn more about how salanersen works in individuals with SMA who are between the ages of 15 and 60 years old. In most people living with SMA, changes to or a lack of a gene called survival motor neuron 1 (SMN1) - often referred to as gene mutations or variants - affect how this gene works. As a result, their bodies produce less SMN protein. Without enough of this protein, motor neurons and muscles cannot work properly. There is a similar gene called SMN2 that produces SMN protein, but it usually does not produce enough SMN protein on its own to make up for the changes in the SMN1 gene. Salanersen is a drug designed to help the SMN2 gene to make more working SMN protein. In this study, there will be 2 groups of participants: a group who has never received treatment for SMA before joining this study, and a group who has been treated with risdiplam, an approved drug for SMA . Those participants must not have received any other SMA treatments before and will need to stop their risdiplam treatment for the duration of the study. The main goal of this study is to learn more about how salanersen affects the participants' motor function. Researchers will use different tests and questionnaires to learn if motor function is changing over the study duration. The main question researchers want to answer in this study is: • For the group who has never been treated for SMA, how much do scores on the HFMSE movement test change at 12 months compared to the beginning of the study? The Hammersmith Functional Motor Scale - Expanded (HFMSE) has 33 activities that are scored which include sitting, lying down, walking, jumping, and more. Researchers will also learn more about: * The effects on participants' motor function and how well their nerves and muscles function. * The effects on participants' overall sense of change and how they perform daily activities. * How many participants have adverse events or serious adverse events. Adverse events are health problems that may or may not be caused by the study drug. * How much salanersen gets into the fluid surrounding the brain and spinal cord. * How much salanersen gets into the blood. This study will be done as follows: * First, participants will be screened to check if they can join the study. The screening period may be up to 4 weeks. * This is an "open-label" study. This is a study in which the participants, study doctor, and site staff will know that participants are receiving salanersen. * All participants will receive salanersen through an intrathecal injection, or one that is given into the fluid surrounding the brain and spinal cord. * Participants will receive salanersen once every year for a total of 5 times throughout the study. * Including screening, participants will have 17 study visits and 9 telephone calls during this study, which will last up to 61 months in total.
NCT06321965
With the advent of new treatments for ASI, new phenotypes are emerging. The investigators propose to describe these new phenotypes by prospectively following children with ASI of all types treated with TRS and aged under 16 for 2 years. The investigators also propose to evaluate potential assessment tools to determine whether they are relevant for monitoring this population, either routinely or for future clinical trials. The investigators also aim to collect the total costs associated with ASI in order to propose a first prospective medico-economic study in France.

Phase 3 pivotal US trial studying open-label intravenous administration of onasemnogene abeparvovec-xioi in spinal muscular atrophy (SMA) Type 1 participants.
NCT07332702
Spinal Muscular Atrophy (SMA) is a severe neuromuscular disease caused by deletion of the SMN1 gene, with the most severe form leading to death in children without treatment. Genetic counselling to detect couples where both partners are carriers is particularly important. In some countries, preconception screening is offered. However, some carriers escape detection due to the existence of two copies of the SMN1 gene side-by-side (2+0 genotype). Currently, no molecular genetic methods used for diagnostic purposes can detect these 2+0 genotypes, which pose a significant challenge in genetic counselling. This study aims to use new technologies based on the analysis of ultra-long molecules to detect side-by-side duplications of the SMN1 gene to detect heterozygous subjects not identified by current techniques and improve genetic counselling.
NCT07265232

NCT02386553
The primary objective of the study is to examine the efficacy of multiple doses of Nusinersen administered intrathecally in preventing or delaying the need for respiratory intervention or death in infants with genetically diagnosed and presymptomatic spinal muscular atrophy (SMA). Secondary objectives of this study are to examine the effects of Nusinersen in infants with genetically diagnosed and presymptomatic SMA.
NCT07208903
The systematic inclusion of spinal muscular atrophy (SMA) in France's neonatal genetic screening (NGS) program, scheduled for September 2025, represents a major milestone in public health. While this screening enables early detection and therapeutic intervention before symptom onset, it also raises psychological and ethical challenges that remain underexplored-particularly during the highly sensitive postpartum period. Currently, data on parental experiences following a positive SMA NGS result are scarce, fragmented, and largely derived from North American studies or from metabolic screening contexts. Early publications highlight high levels of parental anxiety, dissatisfaction with the quality of result disclosure, and difficulties in processing complex medical information in a short, emotionally charged timeframe. These findings underscore the need for a deeper understanding of the subjective processes at play in this situation. The PSYSMA project is designed as an ancillary study to the DEPISMA trial. Its aim is to retrospectively explore parents' lived experiences, their psychosocial support needs, and the impact of NGS on family dynamics and the parent-child relationship. Special attention is given to cases with uncertain results (e.g., ≥4 SMN2 copies without treatment) and false negatives, which remain poorly documented but may trigger unique forms of parental anxiety or adaptation. This research is justified by two main needs: * to guide public health policy toward integrating psychological support from the earliest stages of screening, in line with French National Health Authority (HAS) recommendations; * to generate new knowledge transferable to other genetic diseases that may be included in future neonatal screening programs. The overarching goal is to retrospectively investigate the psychological experience of parents confronted with a positive or false-negative SMA NGS result, in order to analyze its subjective, emotional, and relational effects, as well as related needs for psychological support. Study objectives : * Compare parental experiences according to the nature of the result (with or without treatment indication). * Identify psychosocial support needs, including for siblings. * Assess anxiety, depression, and post-traumatic symptoms associated with NGS. * Explore the broader impact on family functioning, particularly in relation to genetic counseling and communication within the extended family.
NCT05117827
For children who use a power wheelchair, a powered wheelchair standing device (PWSD) may be considered for daily use. A PWSD allows a child to electronically move between sitting and standing and can be driven in either position. Existing published PWSD research in pediatrics is limited to boys with Duchenne muscular dystrophy (DMD).(1, 2) While these studies provide some insights into PWSD use in boys with DMD, they do not reflect PWSD use in children with other conditions. The purpose of this exploratory study is to determine the feasibility of a research protocol exploring use of a PWSD in children who have neurodevelopmental conditions other than DMD.

The aim of this study is to investigate the impact of motor and oral motor functions on the quality of life in children aged 2-4 years diagnosed with Spinal Muscular Atrophy (SMA) Type I. In the study, the Neuro-Sensory-Motor Developmental Assessment (NSMDA) was used to evaluate motor functions, the Functional Oral Intake Scale (FOIS) to assess oral motor function, the Behavioral Pediatric Feeding Assessment Scale (BPFAS) to evaluate children's attitudes towards feeding, and the Pediatric Quality of Life Inventory (PedsQL) Neuromuscular Module to assess quality of life.
NCT05366465
Spinal muscular atrophy is a hereditary motorneuron disease caused by a mutation of the SMN1 gene, which is at the origin of a progressive limb and axial motor deficiency. It concerns 1200 individuals in France, including 700 adults in 2018. The main objective of this study is to assess the quality of life of SMA patients in France. The secondary objectives are, in one hand, to compare the quality of life of SMA patients to a population of neuromuscular diseases patients. And on the other hand to evaluate the determinants of participation and the impact of participation on quality of life in adult SMA patients.
NCT06772402
This study explored dose escalation of single-arm, open, single intrathecal injection in patients with delayed onset type 2 SMA. The investigator plans to conduct 2 cohorts. It is expected that each dose will be enrolled 3 subjects, with a total of 6 subjects aged from 2-12 years old. For safety reasons, first subject of each dose cohort needs to complete a 30-day safety observation. After the researcher determines that the dosing is safe and tolerable, the next two subjects can be enrolled in the cohort; The follow-up dose cohort adopts a sentinel test design, with the first subject of each dose group being a sentinel. During the DLT observation period, if the subject does not observe DLT and the researcher believes that continuing treatment can bring clinical benefits to the subject, the subject will continue to receive treatment; During the DLT observation period, if there is no occurrence of DLT or ≥ grade 2 adverse events related to the investigational drug, it will be escalated to the next dose. If the subject experiences grade ≥ 2 adverse events related to the study drug, the dose will be expanded to 3 subjects for further safety observation. Each subject in each dose cohort will be enrolled on a case by case basis.
NCT04888702
Acti-SMA is a multi-centric academic study. It aims to monitor the progress of patients with spinal muscular atrophy under treatment with Spinraza° or risdiplam. First, we want to quantify improvement of both ambulant and non-ambulant patients under treatment. A secondary objective would also be to identify suitable accelerometric measurements that are sensitive to change but also well correlated to other clinical scores.
NCT06756633
The clinical trial titled "Investigation of Respiratory Functions, Thoracoabdominal Movements, and Exercise Capacity in Neuromuscular Diseases" aims to evaluate the respiratory functions, thoracoabdominal movements, and exercise capacity in children with Duchenne Muscular Dystrophy (DMD) and Spinal Muscular Atrophy (SMA) compared to healthy controls. The study will use spirometry, structured light plethysmography (SLP), the six-minute walk test, and the six-minute pegboard ring test to assess these functions. This trial will be conducted at the Lokman Hekim University Muscle and Nerve Diseases Application and Research Center from May 2024 to Dec 2025.
NCT05638750
An outpatient rehabilitation program for children (6 months to less than 6 years old) with Spinal Muscular Atrophy (SMA) treated with genetic based therapies is being studied. Participants will participate in a 12-week therapy program where they receive 45 minutes each of occupational therapy and physical therapy each week. Home exercises will also be prescribed to be completed 5 days per week. At the end of the therapy program, there will be a 12-week period of no therapy where only home exercises will be completed. Assessments and program evaluation will occur at the beginning (Week 0) and end of the rehabilitation program (Week 24), then at the end of the no therapy block (week 24).
NCT05475691
The natural history of SMA patients has changed, due to the improvements in treatment and technological advances. The systematic collection of data from routine clinical practice in multiple Latin American countries, harmonized to an internationally aligned core data set, is important to advancing the understanding the natural history of disease in the region and the influence of different drug treatments on patient outcomes. These data are critical to improving the care of these patients. So far, clinical trials regarding therapeutic approaches for SMA patients only cover a subgroup of the broad spectrum of severity of SMA. Thus, there is a strong need to monitor the full range of treated and untreated SMA patients in a real-world context.The aim of this study is to set up a regional healthcare provider (HCP) entered registry. The planned SMA registry will provide an online platform to collect longitudinal data on SMA patients across Latin America to achieve a better understanding of the clinical characteristics of SMA patients, the natural history of the disease, the use of DMTs and patients' outcomes, as well as to support further research projects and regional data generation.
NCT06178393
This global, retrospective, non-interventional, medical chart review (MCR), descriptive study collected patient-level data in regions outside the US. The study required a repeated data collection at follow-up dates from start of treatment with nusinersen, onasemnogene abeparvovec-xioi (OA), and/or risdiplam. At the start of data collection, the study team reached out to the health care providers (HCPs) involved in treating pediatric SMA patients for participating in this study. The physicians across the participating countries conducted a retrospective MCR of pediatric patients diagnosed with SMA who were treated with at least 1of the 3 novel disease-modifying treatments (DMTs): nusinersen, OA, and/or risdiplam. All health care encounters data i.e., emergency and inpatient admissions, surgery, and outpatient consultations of recruited patients, including their treatment with nusinersen, OA, and/or risdiplam, were abstracted to understand the treatment patterns as per routine clinical practice for SMA management globally. The first date of initial administration of 1 of the 3 target drugs was used as the "index date." Based on this, the record abstraction was performed through a retrospective MCR during the pre-index period, at index date and in the post-index period.
