Filter by:Sudoscan™ (Impeto Medical, Paris France) uses electrochemical skin conductance as a novel noninvasive method to detect sudomotor dysfunction. Several small studies have recently shown that Sudoscan use in the assessment of small fiber polyneuropathy (in diabetes mellitus) can be performed non-invasively, quickly and effectively. The investigators aim to study the use of Sudoscan in rare disease condition associated with small fiber polyneuropathy.
This is a Phase 2 Open-Label extension study to evaluate the long term safety and tolerability of daily elamipretide injections in patients with genetically confirmed Primary Mitochondrial Disease who previously participated in the SPIMM-202 Clinical Trial
Investigators are recruiting adults (men and women, ages 18 to 65 years, inclusive) with a confirmed genetic diagnosis of mitochondrial disease. Investigators are also recruiting both obese and normal-weight healthy volunteers (men and women, ages 18 to 65 years, inclusive) without a family history of mitochondrial disease to compare to affected individuals. The study involves non-invasive MRI methods and glucose tests to focus on the relationship between mitochondrial disease, obesity, and the risk of diabetes. All study visit procedures will be completed within 2 days, which includes an overnight stay at the Hospital of the University of Pennsylvania. There are no study medications or sedations, and participants will be continually monitored during minimally-invasive procedures (e.g., blood draws). All participants will be able to receive compensation. Furthermore, it may be possible to provide reimbursement for travel, lodging, and meals for individuals with mitochondrial disease. Investigators hope that this research will contribute to the current knowledge of mitochondrial disease and that it will improve diagnostic and treatment approaches.
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), MIDD (Maternally Inherited Diabetes and Deafness), Leigh's Disease and LHON (Leber's Hereditary Optic Neuropathy). The current Proof of Concept study aims to explore the effects of treatment with KH176 for 4 weeks on clinical signs and symptoms and biomarkers of mitochondrial disease and to evaluate the safety and pharmacokinetics of KH176 in patients with m.3242A>G related mitochondrial disease.
Mitochondrial diseases occur due to inadequate energy production. In addition, nitric oxide (NO) deficiency occurs in mitochondrial diseases. The endothelial layer of blood vessels functions in maintaining blood vessels patency through producing NO which relaxes vascular smooth muscles and therefore maintains the patency of blood vessels and adequate blood perfusion. In mitochondrial diseases, endothelial cells fail to perform their normal function in maintaining the patency of blood vessels (endothelial dysfunction) because of the inability to produce enough NO. Endothelial dysfunction results in decreased blood perfusion in different organs which can contribute to the complications seen in mitochondrial diseases. The amino acids arginine and citrulline act as NO precursors and can increase NO production. In this study we hypothesize that due to the inability to produce enough NO patients with mitochondrial diseases have endothelial dysfunction that will improve after arginine or citrulline supplementation. The investigators will assess endothelial function using peripheral arterial tonometry before and after arginine or citrulline supplementation. The investigators expect that arginine and citrulline supplementation will improve endothelium function. This will support the therapeutic use of arginine and citrulline in mitochondrial diseases.
This randomized, double-blind, placebo-controlled, crossover study screened 32 subjects with primary mitochondrial myopathy (PMM) to evaluate the safety, tolerability, pharmacokinetics (PK), and efficacy of subcutaneous elamipretide in this patient population.
The purpose of this study is to develop preliminary evidence, such as effect size and variance estimates, to guide successful conduct of a properly-powered clinical trial to assess the benefit of a mitochondrial cocktail (incorporating individualization of treatment) in Gulf War illness (GWI).
Mitochondrial disorders are a group of inherited disorders causing malfunctional mitochondria. Mitochondria are found in every cell of the body, and the disorders therefore give symptoms from every tissue, especially those with high energy needs as the brain, heart and muscles. The symptoms are often unspecific in terms of muscle weakness and fatigue, which delays the first contact to the doctor and further delays the diagnosis. The aim of this study is to investigate if it is possible to use GDF-15 (Growth and Differentiation Factor 15) as a biomarker for mitochondrial disease and compare the results with that of healthy controls, metabolic myopathies and muscular dystrophies. The concentration relative to exercise will further be investigated.
Mitochondrial disorders are a group of inherited disorders causing malfunctional mitochondria. Mitochondria are found in every cell of the body, and the disorders therefore give symptoms from every tissue, especially those with high energy needs as the brain, heart and muscles. The disorders are highly disabling. The aim of the study is to investigate the relation between muscle strength and contractile cross sectional area (CCSA) in the leg of patients affected by mitochondrial diseases. The hypothesis is that there can be a disrupted relationship between strength and CCSA.
The investigators will evaluate whether sulfamethoxazole, a sulfamide antibiotic, improves the symptoms of primary PREPL deficiency (hypotonia-cystinuria syndrome and isolated PREPL deficiency).
