Optic atrophy with or without deafness, ophthalmoplegia, myopathy, ataxia, and neuropathy

This study tests whether injecting a person's own bone marrow stem cells into or near the eye can help treat various retinal and optic nerve diseases, including age-related macular degeneration, retinitis pigmentosa, and glaucoma. Participants receive stem cell injections via dif…

This study tests a special camera that takes detailed images of the retina using many wavelengths of light. Researchers hope it can find early signs of eye diseases like age-related macular degeneration, diabetic retinopathy, and glaucoma. About 1,000 adults in Melbourne, Austral…

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 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 create a database of eye images using a new holographic Doppler laser device. The goal is to better visualize and measure blood flow in the retina and choroid, which is important for diagnosing eye diseases. About 123 adults, both with and without eye condition…

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…
