Active clinical trials for "Leigh Disease"

This a randomized placebo controlled, double-blind phase II study to explore the pharmacokinetics, safety and efficacy of sonlicromanol in children (from birth to 17 years) with genetically confirmed mitochondrial disease of which the gene defect is known to decrease one or more oxidative phosphorylation system enzymes and who suffer from motor symptoms ("KHENERGYC").

EPI-743 in Leigh syndrome participants that participated in previous EPI743-12-002 (NCT01721733) study.

This is a parallel-arm, double-blind, placebo-controlled study with a screening phase that includes a 28-day run-in phase to establish baseline seizure frequency, followed by a 24-week, randomized, placebo-controlled phase. After completion of the randomized, placebo-controlled phase, participants may enter a 48-week, long-term, extension phase during which they will receive open-label treatment with vatiquinone.

The main goal of the project is provison of a global registry for mitochondrial disorders to harmonize previous national registries, enable world-wide participation and facilitate natural history studies, definition of outcome measures and conduction of clinical trials.

The purpose of this study is to develop a database containing clinical and laboratory information for patients with Leigh syndrome. The goal is to provide a greater understanding of Leigh syndrome allowing further characterization of this disease.

The Metabolism, Infection and Immunity (MINI) Study is a longitudinal natural history study at the National Institutes of Health (NIH) that aims to define the relationship between infection, immunity and clinical decline in individuals with mitochondrial disease. Mitochondrial diseases are a group of disorders caused by problems with the cell s ability to produce energy. Infection in individuals with mitochondrial disease can lead to worsening clinical symptoms, particularly neurologic symptoms. Goals: The main goal of our study is to understand the relationship between infection and clinical decline in patients with mitochondrial disease. Mitochondrial diseases can affect many different parts of the body, including the immune system and its ability to respond to infection. Therefore, we perform a comprehensive evaluation of participants including a detailed immunologic assessment. We are not testing any new medicine or procedure to treat or cure IEM or mitochondrial diseases. However, by understanding the relationship between infection and mitochondrial disease, we hope to develop treatments in the future. At the NIH, we are interested in research. Although we do provide advice and care for people enrolled in our study, we are not able to take over the long-term care of participants. To enroll in our study, you (your child) must already have a confirmed diagnosis of a mitochondrial disease. We are not able to provide a "first time" diagnosis or regular metabolic care. What is involved? Once you contact our team members, you will be asked to provide medical records to determine eligibility. Our team will review the records and notify you if you (your child is) eligible to join the study. -Onsite participation: You (your child) will be invited to visit the National Institutes of Health in Bethesda, Maryland. This first visit will typically last 3-5 days. Depending on the level of participation, additional visits may be requested. Our team members will work with you and your child to coordinate the supports needed during your stay at NIH. Study participants may be seen in the clinic, day hospital or inpatient setting. When you (your child) arrive at the NIH we will have an informed consent discussion to confirm willingness to participate, answer questions and review the risks and benefits of the study. You (your child) will meet with a physician who will ask about medical and family history and do a physical exam (like in any doctor's office). We will ask all study participants to allow us to collect urine, draw blood, swab your (your child s) nose, and perform a detailed assessment. We may suggest additional evaluations or specialty consults for some participants based on clinical manifestations, age and level of independence. We will explain these studies to you (your child). They may include items such as- imaging studies, DEXA or MRI scan, energy expenditure or metabolic testing, developmental neuropsychological logical testing, physiatry, ophthalmology, or other consults. In some cases, we may request a skin biopsy (if one has not been done). You will receive the results of your (your child's) clinical testing and notes from any clinical consultations. -Remote participation: If you (your child) are unable to travel, you (your child) may be enrolled remotely for records review, questionnaires, and telethealth exams. Blood or other samples collection may be requested in coordination with local providers or lab testing companies

The investigators are studying patients with undefined mitochondrial diseases to identify genetic mutations in nuclear or mitochondrial Deoxyribonucleic Acid (DNA). Most patients with suspected or known mitochondrial diseases have no genetic confirmation. The investigators expect that evaluating tissue samples from patients with mitochondrial disorders will lead us to discover mutations in new or known genes causing mitochondrial dysfunction.

CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.

To evaluate safety, tolerability and efficacy of cysteamine bitartrate delayed-release capsules (RP103) administered up to 1.3 g/m²/day in two divided doses, every 12 hours, for up to 6 months in patients with inherited mitochondrial disease.

Mitochondrial Diseases are rare progressive, multi-system, often early fatal disorders affecting both children and adults. KH176 is a novel chemical entity currently under development for the treatment of inherited mitochondrial diseases, including MELAS (Mitochondrial Encephalomyopathy, Lactic acidosis, and Stroke-like episodes), Leigh's Disease and Leber's Hereditary Optic Neuropathy (LHON). KH176 is a potent intracellular redox modulating agent targeting the reactive oxygen species which are important in the pathogenesis of disorders of mitochondrial oxidative phosphorylation. After demonstrating a favourable safety profile in the pre-clinical testing, the safety, tolerability and pharmacokinetic and pharmacodynamic characteristics of the compound will now be evaluated in healthy male subjects in this trial
