View clinical trials related to Mitochondrial Diseases.
Filter by:Primary Mitochondrial diseases are a clinically and genetically heterogeneous group of disorders caused by mutations in genes encoded by nuclear Deoxyribonucleic Acid (DNA) or by mutations and/or deletions in the mitochondrial DNA (mtDNA). While some mitochondrial disorders only affect a single organ (e.g., the eye in Leber hereditary optic neuropathy [LHON]), many involve multiple organs. Mitochondrial disorders may present at any age and a frequent feature is the increasing number of organs involved in the course of the disease. Minovia Therapeutics Ltd. ("Minovia") is a biotech company developing novel therapeutics based on its mitochondrial augmentation technology (MAT). MNV-201 is a cell therapy produced by MAT that consists of the participant's autologous CD34+ hematopoietic stem and progenitor cells (HSPCs) enriched with allogeneic placental-derived mitochondria, manufactured in Minovia's GMP facility.
The goal of this clinical trial is to learn about the treatment effects of the investigational new drug OMT-28 in patients with Primary Mitochondrial Disease. The main question[s] it aims to answer are: - Is OMT-28 safe and well tolerated in this patient population? - Does OMT-28 reduce Growth Differentiation Factor 15 (GDF-15) and other relevant blood markers of mitochondrial dysfunction and inflammation? - Does OMT-28 improve symptoms of the disease, e.g. fatigue or exercise intolerance? Participants will be asked to participate in 6 study visits at an experienced clinical center, including physical examinations and exercise tests, and take the study medication regularly once per day according to the protocol. Researchers will compare for every participant the results after 3 months and 6 months of treatment with a preceding 3 month period of standard care treatment to investigate the effects of OMT-28 on clinical parameters and a number of blood parameters.
Diabetes can lead to heart failure independently, but the underlying causes remain incompletely understood. The main aim of this study is to identify differential regulation of mitochondrial substrate utilization and complex activity in heart failure and type 2 diabetes mellitus (T2DM). For this, we will conduct a prospective, observational study to examine myocardial mitochondrial oxidative function and related metabolic parameters, gene expression, histological markers, and inflammation in cardiac tissue from patients with heart failure or patients after heart transplantation. We will further assess cardiac function using cardiac magnetic resonance imaging with and without stress protocols and magnetic resonance spectroscopy. Glycemic control/T2DM will be characterized by oral glucose tolerance tests. The results of this project will help to better understand the cellular mechanisms of the development of diabetic cardiomyopathy and contribute to the development of early diagnostic, as well as therapeutic approaches for the prevention and treatment of diabetic cardiomyopathy.
Background: Small-Fiber-Neuropathy describes the degeneration of mildly or unmyelinated nerve fibers and causes neuropathic pain and autonomic dysfunction. Gold standard for the diagnosis is a small skin punch biopsy from the lower leg and the histological quantification of the intraepidermal nerve fiber density (IENFD). In children, the normal IENFD has not been systematically assessed and normal reference values are needed. In Parkinson´s disease, the neurodegeneration also affects the peripheral nerves and SFN is present already in the early stages. Whether neurodevelopmental disorders (NDDs) in childhood are likewise associated with SFN is largely unknown. The IENFD is age-dependent and declines with age. Aims: In this study, we are establishing the reference values for the physiological IENFD in children from 0-18 years. Moreover, we are investigating if children with NDDs have a reduced IENFD and if SNF is a clinically relevant cause of pain and autonomic dysfunction.
This is a multi-aim study, studying the effects of conventional exercise (measured through Cardiopulomary Exercises Testing or an in-bed pedal exercise) and passive exercise through periodic acceleration (pGz). Aim 1 will focus on the differences between primary mitochondrial disease (PMD) patients and healthy volunteers. Aim 2 is an exploratory aim, which will be studying the effects in patients admitted to the Children's Hospital of Philadelphia Pediatric Intensive Care Unit (PICU).
The main goal of the project is provision 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.
Cell and mice studies suggest mitochondrial dysfunction may cause altered bone structure. Hypothesis: Decreased mitochondrial energy production affects bone cell development and activity negatively. Comparing humans with the mitochondrial DNA variant, m.3243A>G, pathogenic variants in POLG or TWNK genes to healthy controls, the aim is to evaluate the effect of mitochondrial dysfunction on: 1: bone-cell development and -activity in bone marrow stem cells and blood. 2: bone cell metabolism including glucose consumption. 3: bone structure assessed by electron microscopy and μCT scans of bone biopsies.
Investigators have assembled an existing infrastructure of physical therapists, clinical coordinators and Bioinformatics; as well as expertise in developing and validating tools to measure disease course in a longitudinal study, to support completion of the proposed studies. Aim 1 serves to validate the Mitochondrial Myopathy Objective Assessment Tool (MM-COAST) and Mitochondrial Myopathy Functional Scale (MMFS) in nucleotide-binding protein-like (NUBPL)-subjects. Aim 2 aims to devise a Primary Mitochondrial Diseases (PMD)-specific cerebellar ataxia outcome measure for future clinical trials. Nucleotide-binding protein-like (NUBPL)-Natural history data will be used to inform future interventional clinical trial design, while the validated MM-COAST, Mitochondrial Myopathy Rating Scale (MMRS) and newly devised PMD-ataxia scale would be utilized as meaningful quantitative outcome measures in future NUBPL-multicenter natural history and clinical trials.
N-Acetylcysteine (NAC), an anti-oxidant, will be studied to investigate the effects on brain glutathione levels, cognitive skills, motor skills, and quality of life. A group of 18 participants will take either 1800, 3600 or 5400 mg per day of N-acetylcysteine (NAC) for 3 months in this dose escalation study. The investigators want to determine first if the 3600 mg dose per day is safe and might provide some efficacy. If the 3600 mg dose is safe, then additional participants will be treated with 5400 mg per day of NAC, for up to a total of 18 participants. If the 3600 mg per day dose is unsafe, then participants will be treated with the 1800 mg per day dose. Data from this pilot study will be used to determine the most safe and effective dose of NAC for a future clinical trial.
This study is an observational longitudinal study involving the use of MRIs and video recordings taken at home of patients completing basic tasks. Once consent is obtained, subjects will be asked to schedule an appointment with radiology to undergo the listed MRIs of the heart and/or muscle. Subjects will also be given instructions on how to use the video recording app on their personal devices, or study provided device. The subjects will be followed regularly over the course of two years, submitting video recordings of their movements and reporting to Mayo Clinic for MRIs as scheduled.
