MYOTONIC DYSTROPHY TYPE-1

This study tests a gene therapy called SAR446268 for people aged 10 to 55 with myotonic dystrophy type 1. The therapy is given once through an IV and aims to reduce harmful DMPK RNA and improve muscle function. The trial has two parts: first, finding the safest dose in a small gr…

This Phase 3 trial tests whether a once-daily dose of mexiletine PR can safely reduce muscle stiffness (myotonia) in people with myotonic dystrophy types 1 and 2. About 176 participants will receive either the drug or a placebo for 26 weeks. The main measure is how quickly hand m…

This study follows up to 10 children from birth to under 6 years old who have genetic muscle disorders causing stiffness (myotonia) and are taking mexiletine. Researchers will collect data on side effects and how the medicine is used in routine care over the long term. The goal i…

This study follows 1,000 adults with myotonic dystrophy type 1 (DM1) over time to measure how the disease progresses. Researchers will track walking speed, hand muscle relaxation, grip strength, heart and lung function, and daily activity. The goal is to establish reliable biomar…

This study aims to learn why myotonic dystrophy type 1 affects children differently than adults, and why symptoms vary even within the same family. Researchers will observe 100 children (ages 0-17) through video calls and simple at-home activities, and analyze their genes from a …

This study aims to create a national registry for people with Myotonic Dystrophy Type 1 (DM1) in Spain. Researchers will collect clinical data, genetic information, and patient reports from up to 3,000 participants. The goal is to better understand the disease and identify people…

This study is looking for 75 adults with myotonic dystrophy (a muscle disease) and healthy volunteers to test new muscle imaging techniques. The goal is to find better ways to measure muscle changes over time, which could help future treatment studies. Participants will undergo M…

This study aims to find less invasive ways to measure muscle disease activity in people with muscular dystrophies. Instead of painful muscle biopsies, researchers will use blood and urine samples along with painless ultrasound and electrical tests on the arms and legs. The goal i…

This study looks at the spinal fluid and brain activity of people with myotonic dystrophy type 1, a condition that affects muscles and thinking. Researchers want to find early signs of disease in the fluid that surrounds the brain. About 88 adults will take part, including some w…

This study aims to find less invasive ways to measure disease activity in myotonic dystrophy by looking for RNA markers in blood and urine instead of taking muscle biopsies. Researchers will compare samples from 215 people with and without the condition to see if these markers ca…

This registry aims to connect people diagnosed with myotonic dystrophy (DM) or facioscapulohumeral muscular dystrophy (FSHD) with researchers. By joining, participants help scientists better understand these inherited muscle-weakening diseases and develop future treatments. The r…
