MERRF syndrome

This Phase 3 trial tests a single inhaled dose of alprazolam (a fast-acting sedative) to stop prolonged seizures in people aged 12 and older. The goal is to see if it can end a seizure within 90 seconds and prevent it from coming back for at least 2 hours. About 350 participants …

This trial is testing the long-term safety of brivaracetam, an anti-seizure medication, when used alongside other epilepsy treatments in children. Researchers are monitoring for side effects, including serious ones, over an extended period. The study includes children who previou…

This study is testing a handheld device called mScan that uses a tiny, painless electrical current to measure muscle health. Researchers want to see if it can give similar results to an MRI, but faster and more conveniently. The study involves 150 adults with and without muscle d…

This study tests whether cycling while using a virtual park app can slow the loss of motor function in children and teens with neuromuscular diseases like muscular dystrophy. Twenty-two participants will first receive standard care for 3 months, then use the virtual park bike 3 t…

This Phase 2 trial tests whether KL1333 can reduce fatigue and improve leg strength in adults with primary mitochondrial disease, a genetic condition that affects energy production. About 180 participants will receive either KL1333 or a placebo twice daily for 48 weeks. The study…

This study at the National Institutes of Health looks at how infections can worsen symptoms in people with mitochondrial disease, a group of disorders that affect energy production in cells. Researchers will evaluate participants' immune systems through blood tests, physical exam…

This study creates a global registry for people with mitochondrial disorders—rare diseases that affect energy production in cells. By collecting health data from 6,000 participants worldwide, researchers aim to understand how these diseases progress and identify the best ways to …

This study aims to learn more about rare inherited disorders that affect the brain, spinal cord, muscles, and nerves. Researchers will collect medical history, perform exams, and run genetic tests on up to 3,500 participants. No new treatments are tested; the goal is to better un…

This study investigates how rehearsal (repeating information) and sleep help solidify memories in people with epilepsy. Participants learn object-location pairs, with some pairs rehearsed and others not, and their memory is tested after a short delay and again after 12 hours—eith…

This study is looking at whether a molecule in the blood called miR-1 can help doctors understand how muscle diseases like Duchenne muscular dystrophy and myotonic dystrophy are progressing. Researchers will compare miR-1 levels in 104 people, including patients with different mu…

This study is creating a large registry and tissue bank for people with mitochondrial disorders. Researchers will collect medical information and samples from up to 1,000 participants, including those diagnosed with or suspected to have a mitochondrial disease. The goal is to gat…

This study aims to find better ways to measure fatigue and walking problems in people with neuromuscular diseases like muscular dystrophy and spinal muscular atrophy. Researchers will use a wearable sensor to track physical activity for one week in daily life and during a walking…

This study uses powerful MRI scanners to look at the brains and spinal cords of 700 people, including healthy volunteers and those with conditions like multiple sclerosis, Alzheimer's, and Parkinson's. The goal is to understand why some brains stay healthy while others decline. R…

This study collects blood and skin samples from 100 people with primary mitochondrial diseases and healthy volunteers aged 3 to 85. Researchers will study how different mitochondrial mutations affect cell function and look for biomarkers. The samples will also help test a new the…
