Resveratrol Supplementation in Patients With Mitochondrial Myopathies and Skeletal Muscle Fatty...

Mitochondrial MyopathiesFatty Acid Oxidation Defects

The purpose of this study is to investigate the potential beneficial effects of a daily supplement of Resveratrol (1000mg/day) on physical ability and on muscle metabolism in patients with verified mitochondrial myopathy and patients with a verified fatty acid oxidation defect of VLCAD and CPTII deficiencies. Investigators hypothesize an improved muscle metabolism, mitochondrial function, fatty acid oxidation and thus improvement of physical ability.

This will be a double blind, randomised, placebo controlled, single and multiple oral dose study conducted in 3 parts: Part A, Part B and Part C. Part A and Part B include healthy volunteers only and will be completed before Part C including patients with primary mitochondrial disease will be initiated. The starting dose in the first cohort of Part A will be 25 mg. The dose level in the additional cohorts will be decided following review of data of the previous cohorts.

The KHENERGY Study

Mitochondrial DiseasesMitochondrial Myopathies3 more

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.

RTA 408 Capsules in Patients With Mitochondrial Myopathy - MOTOR

MItochondrial Myopathies

Mitochondrial myopathies are a multisystemic group of disorders that are characterized by a wide range of biochemical and genetic mitochondrial defects and variable modes of inheritance. Currently there are no effective treatments for this disease. Despite the heterogeneous myopathy phenotypes, a unifying feature of mitochondrial myopathies is that the pathogenic mtDNA mutations and/or nuclear mutations of the electron transport chain invariably lead to dysfunctional mitochondrial respiration. This reduction in mitochondrial respiration leads to a reduced ability to produce cellular adenosine triphosphate (ATP), often resulting in muscle weakness, exercise intolerance, and fatigue in patients with mitochondrial myopathies. RTA 408 is a potent activator of Nrf2 and inhibitor of NF κB (nuclear factor kappa-light-chain-enhancer of activated B cells), and thus induces an antioxidant and anti-inflammatory phenotype. Several lines of evidence suggest that Nrf2 activation can increase mitochondrial respiration and biogenesis. Collectively, available data suggest that the ability of RTA 408 to activate Nrf2 and induce its target genes could potentially improve muscle function, oxidative phosphorylation, antioxidant capacity, and mitochondrial biogenesis in patients with mitochondrial myopathies. This study will be a randomized, placebo-controlled, double-blind, dose-escalation study to evaluate the safety of omaveloxolone (RTA 408) at various doses in patients with mitochondrial myopathies.

Nicotinamide Riboside and Mitochondrial Biogenesis

Mitochondrial DiseasesMitochondrial Myopathies6 more

Mitochondria are important parts of the cell that are responsible for producing energy. The amount of energy they produce depends on how much energy the body needs to function and this energy production can be severely impaired in people with mitochondrial disease. Symptoms of mitochondrial disease vary widely but usually involve the brain, nerves and muscles, as these are tissues that need a lot of energy. Mitochondrial disorders affect 1 in 5000 of the UK population and there is currently no cure. Some scientists think that increasing the number of mitochondria in the body (mitochondrial biogenesis) might be an effective treatment for the symptoms of mitochondrial disease. Studies carried out in mice have shown that a type of B-vitamin called Nicotinamide Riboside (NR) is able to increase the number of mitochondria, leading to increased energy and a reduction in the symptoms of mitochondrial disease. The aim of this study is to investigate if the same B vitamin, Nicotinamide Riboside, can increase energy production and reduce symptoms in humans with mitochondrial disease. The study will consist of two parts: Part 1: Participants will be given a single oral dose of Nicotinamide Riboside and the levels of NR in their bloodstream will be measured at regular intervals. This will involve a single overnight stay and simple blood tests. Part 2: This requires 6 separate visits from each participant. Each participant will undergo a series of standard tests including a muscle biopsy and an MRI scan, then they will take a course of Nicotinamide Riboside (twice daily for 4 weeks). After 4 weeks of treatment, the participants will undergo the same tests again to see if there have been any changes in response to the treatment.

mtDNA Mutation Load Analysis in Mesoangioblasts

Mitochondrial Myopathies

Mitochondrial diseases caused by defects in oxidative phosphorylation (OXPHOS) due to heteroplasmic mitochondrial DNA (mtDNA) mutations are rare (frequency 1/5,000), but severe multi-system disorders. Clinical manifestations are highly variable, but predominantly affect energy demanding tissues, like brain and muscle. Myopathy is a common feature of mtDNA disorders, being present in more than 50% of the mtDNA mutation carriers, and seriously affects patients' general well-being and quality of life. Currently, no treatment is available for these patients, although the induction of muscle regeneration by exercise treatment has been shown to alleviate their myopathy. This implies that these patients can produce muscle fibres that perform better, most likely because the mutation load is lower. Mesoangioblasts (MABs) are myogenic precursors that have been recognized as a source for development of a systemic myogenic stem-cell therapy. Autologous MABs may be feasible for half of the mtDNA mutation carriers of 6 different mtDNA mutations, as their mtDNA mutation load in mesoangioblasts was (nearly) absent (<10%). However, there are many more mtDNA mutations in the 16.5kb mtDNA and the aim of this study is to determine the mtDNA mutation load in mesoangioblasts of other mtDNA mutation carriers and identify the patients or mutations for which this is a feasible approach.
