Active clinical trials for "Muscular Atrophy, Spinal"

This is a long-term follow-up safety and efficacy study of participants in clinical trials for spinal muscular atrophy (SMA) who were treated with onasemnogene abeparvovec-xioi. Participants will roll over from their respective previous (parent) study into this long-term study for continuous monitoring of safety as well as monitoring of continued efficacy and durability of response to onasemnogene abeparvovec-xioi treatment.

The goal of this clinical trial is to study respiratory muscle training in patients with Spinal Muscular Atrophy (SMA). The main questions it aims to answer are: Is a home-based individualized training program for the inspiratory and expiratory muscles feasible (good adherence and good acceptability)? Can a home-based individualized training program for the inspiratory and expiratory muscles increase the strength of these muscles? Participants will be asked to perform 10 training sessions per week, spread out over 5-7 days. Each training session consists of 30 breathing cycles through the inspiratory muscle trainer and 30 breathing cycles trough the expiratory muscle trainer. In the first four months of the study researchers will compare two groups to see if a higher trainings load is more effective. One group will start at a trainings load of 10% of their maximal inspiratory and expiratory muscle strength. The other group will start at a trainings load of 30% of their maximal inspiratory and expiratory muscle strength. This group also need to adjust the trainings load based on their perceived exertion. After four months all participants will train on a trainings load of 30% of their maximal inspiratory and expiratory muscle strength and adjust the trainings load based on their perceived exertion. The participants will come to the hospital for lung function tests every four months for 12 months.

This trial will study the efficacy and safety of taldefgrobep alfa as an adjunctive therapy for participants who are already taking a stable dose of nusinersen or risdiplam or have a history of onasemnogene abeparvovec-xioi, compared to placebo.

The primary objectives of this study are to examine the clinical efficacy of nusinersen administered intrathecally at higher doses to participants with spinal muscular atrophy (SMA), as measured by change in Children's Hospital of Philadelphia-Infant Test of Neuromuscular Disorders (CHOP-INTEND) total score (Part B); to examine the safety and tolerability of nusinersen administered intrathecally at higher doses to participants with SMA (Parts A and C). The secondary objectives of this study are to examine the clinical efficacy of nusinersen administered intrathecally at higher doses to participants with SMA (Parts A, B and C); to examine the effect of nusinersen administered intrathecally at higher doses to participants with SMA (Parts A and C); to examine the safety and tolerability of nusinersen administered intrathecally at higher doses to participants with SMA, to examine the effect of nusinersen administered intrathecally at higher doses compared to the currently approved dose in participants with SMA (Part B).

Multi-center, randomized, double-blind, placebo-controlled study to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of Risdiplam in adult and pediatric participants with Type 2 and Type 3 SMA. The study consists of two parts, an exploratory dose finding part (Part 1) of Risdiplam for 12 weeks and a confirmatory part (Part 2) of Risdiplam for 24 months.

A global study of oral risdiplam in pre-symptomatic participants with spinal muscular atrophy (SMA).

The TOPAZ study will assess the safety and efficacy of SRK-015 in later-onset Spinal Muscular Atrophy (SMA Type 2 and Type 3) in pediatric and adult patients.

The primary objective of this study is to evaluate the clinical outcomes following treatment with Nusinersen in participants with spinal muscular atrophy (SMA) who previously received onasemnogene abeparvovec. The secondary objectives of this study are to evaluate the safety and tolerability; and clinical outcomes following treatment with Nusinersen in participants with SMA who previously received onasemnogene abeparvovec.

The ONYX study is an Open-Label, Multicenter, Extension study that will evaluate the long-term safety and efficacy of Apitegromab in Patients with Type 2 and Type 3 SMA who have completed TOPAZ or SAPPHIRE.

This is a multi-center, exploratory, non-comparative, and open-label study to investigate the safety, tolerability, PK, and PK/PD relationship of risdiplam in adults, children and infants with Spinal Muscular Atrophy (SMA) previously enrolled in Study BP29420 (Moonfish) with the splicing modifier RO6885247 or previously treated with nusinersen, olesoxime or AVXS-101.
