139 Clinical Trials for Various Conditions
The purpose of this expanded access program is to enable access to R007 (probucol) tablets for the compassionate treatment of adults with mitochondrial disease who also have chronic kidney disease.
Primary Mitochondrial Disease (PMD) is a genetic neurometabolic disorder, leading to central nervous system degeneration and increased risk of early mortality. There is a strong link between the pathophysiology of mitochondrial disease and biomarkers related to the biochemistry of redox imbalance, involving the levels of glutathione. Investigators will use Magnetic Resonance Imaging and Spectroscopy to non-invasively measure glutathione and other chemicals in the brain to identify redox imbalance in patients with PMD.
The goal of this study is to find the best way to help people with primary mitochondrial disease deal with the stress of their condition, and to help these people be better able to "bounce back," or be resilient. In order to do this, the investigators are going to test two interventions (an intervention means that it aims to change something): Promoting Resilience in Stress Management (PRISM) and clinical-focused narrative (CFN) intervention.
The primary objective of the FALCON study is to evaluate the efficacy of KL1333 on selected disease manifestations of primary mitochondrial disease (PMD) following 48 weeks of treatment. This objective involves evaluating the efficacy of KL1333 versus placebo on fatigue symptoms and impacts on daily living as well as on functional lower extremity strength and endurance. Additionally, the study evaluates the safety and tolerability of KL1333.
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 primary objective of this study is to assess the safety of vatiquinone in participants with inherited mitochondrial disease who had prior exposure to vatiquinone in a PTC/BioElectron sponsored (previously Edison) clinical study or treatment plan. The study will continue until vatiquinone becomes commercially available or the program is terminated.
SPIMD-301 is a 48-week, randomized, double-blind, parallel-group, placebo-controlled trial to assess efficacy and safety of single daily subcutaneous (SC) administration of elamipretide as a treatment for subjects with primary mitochondrial myopathy associated with nuclear DNA mutations (nPMD).
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.
The purpose of this study is to perform a "muscle phenotyping" magnetic resonance imaging (MRI) assessment in patients receiving clinical care at the Children's Hospital of Philadelphia (CHOP) for mitochondrial disease that is either suspected (based on clinical presentation) or has a definite genetic diagnosis. The MRI assessment quantifies skeletal muscle oxidative phosphorylation (OXPHOS) capacity. Investigators hope that this study will contribute to our current knowledge of mitochondrial diseases and this study will help create a new diagnostic tool for use in both clinical care and in clinical trials.
Background: Mitochondrial disease is a rare disorder. It can cause poor growth, developmental delays, muscle weakness, and other symptoms. The disease is usually inherited. It can be present at birth or develop later in life. Infection is a major cause of disease and death in people with this disease. Researchers want to learn more about these infections and the declining health of people who have this disease. To do this, researchers will study the DNA of people who become ill. Their DNA will be compared to the DNA of their household/family members. Objective: To learn more about how genes affect people with mitochondrial disease. Eligibility: People age 2 months and older with mitochondrial disease and their household/family members. .\<TAB\> Design: Participants will complete a questionnaire about their health history. Their medical records may be reviewed. They will give a blood sample. If the participant becomes ill, they may have a videoconference with a doctor or nurse at the NIH to perform a physical exam. They may be contacted after their illness to give updates on their health. They may be asked to give extra blood samples or complete extra questionnaires. Participants genetic data will be put into a database. The data will be labeled with a code and not their name. The data will be shared with other researchers. Participation lasts about 1 year. This may be extended if the participant is very ill.
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.
This is an observational study of patients with Primary Mitochondrial Disease with either signs or symptoms suggestive of myopathy. The Investigator will identify potential patients through existing medical records and one on-site visit.
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.
A long-term extension study to assess the safety, tolerability and efficacy of cysteamine bitartrate delayed-release capsules (RP103) in children with inherited mitochondrial diseases who previously enrolled into study RP103-MITO-001 (NCT02023866).
The purpose of this study is to learn about the use of nutritional supplements in patients with mitochondrial disease.
The investigators are conducting a research study on nutrition in mitochondrial disease. The investigators are interested in the kind of carbohydrates that people eat. Carbohydrates are an important source of energy. Certain kinds of carbohydrates tend to raise blood sugar more in healthy people, and others tend to raise blood sugar less in healthy people. The investigators would like to know if by eating the "right" type of carbohydrate, people with mitochondrial disease can avoid high lactate levels, high blood sugar levels, and, later, low blood sugars. In this study, this question will be answered by finding out how people with mitochondrial disease respond to two different test meals containing different kinds of carbohydrates. Neither participants nor the investigators will know which kind of test meal participants are eating.
The purpose of the study is to use a new research imaging technique, a kind of magnetic resonance imaging (MRI), to measure important metabolic features of muscle, including mitochondrial function, in people with mitochondrial disease and in healthy individuals. (Mitochondria are tiny organelles that generate energy for the body.) It is hoped that this new strategy will help physicians to understand better the health problems of people with mitochondrial disease. Eventually, this could lead to better diagnostic and treatment approaches.
This pilot study is a prospective, randomized clinical trial to evaluate the effect of anesthesia in the mitochondrial dysfunction patient.
To evaluate safety, tolerability and efficacy of cysteamine bitartrate delayed-release capsules (RP103) administered at a target maintenance dose of 1.3 g/m²/day in two divided doses, every 12 hours, for up to 6 months in patients with inherited mitochondrial disease.
The purpose of this study is to determine whether therapy that has been shown to be beneficial for mitochondrial diseases is also beneficial for Chronic Fatigue Syndrome (CFS) patients. This study is a chart review of previous CFS patients who received daily conditioning exercise, a high protein diet and nutraceutical therapy (ENT). Prescribed nutraceutical supplements included alpha-lipoic acid, acetyl-L-carnitine, omega-3fatty acids (maxDHA), coenzyme Q10 (CoQ10), plus a multivitamin. Twelve CFS male and female patients between the ages of 20-70 years will be recruited to participate in this pilot study. Subjects will be eligible to participate if they meet the criteria for CFS of the Centers for Disease Control and Prevention (CDC). These include persistent, unexplained fatigue for at least 6 months, concurrent with four of the following: impaired memory/concentration, sore throat, new headaches, unrefreshing sleep, muscle pain, multi-joint pain, tender lymph nodes, and post-exertional malaise.
This pilot clinical study evaluated the safety and metabolic responses to a licensed inactivated seasonal influenza vaccine (TIV) in mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes syndrome (MELAS) volunteers and controls.
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.
The North American Mitochondrial Disease Consortium (NAMDC) maintains a patient contact registry and tissue biorepository for patients with mitochondrial disorders.
Background: * Mitochondria are the parts of cells that help produce energy. Metabolism is the process by which the body uses energy to help cells grow and reproduce. Metabolic and mitochondrial disorders affect the body s ability to produce and store energy. These disorders can cause a wide variety of problems, but most often they affect the muscles and the brain, where energy requirements are high. Treatment is difficult because the exact source of the problem is hard to detect. * EPI-743 is a new drug that is based on vitamin E. Tests have shown that it can help improve the function of cells with mitochondrial problems. It may be able to treat people with genetic disorders that affect metabolism and mitochondria. Objectives: - To see if EPI-743 can improve energy production and use in people with mitochondrial or metabolic disorders. Eligibility: - Children between 2 and 11 years of age who have metabolic or mitochondrial problems. Design: * Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. * The study will last about 13 months. Participants will have seven 3- to 5-day inpatient study visits about 3 months apart. * Participants will take either EPI-743 or a placebo for the first 6 months of the study. After 6 months, there will be a 1-month rest period. Then, those who received EPI-743 in the first 6 months will take the placebo for the next 6 months. Those who had the placebo will take EPI-743. * During each inpatient study visit, participants will have a physical exam. A 24-hour urine collection will be obtained. Blood samples will also be taken. Imaging studies and other tests may be performed as directed by the study researchers.
Carriers of the m.3242A\>G mutation often have clinical symptoms which can include migraines, seizures, strokes, hearing loss, balance issues, gastrointestinal issues, and many other symptoms. The investigators would like to learn more about these disorders and have designed a "Natural History Study" to monitor these conditions over time so that physicians and scientists can not only understand the problems that patients have, but work on developing treatments. The focus of the current work is to evaluate known mutation carriers of the m.3243A\>G (mitochondrial DNA) and their maternal relatives (carrier status not a requirement for participation). Paternal relatives will serve as controls. This study involves no treatment.
The pathogenesis of chronic fatigue syndrome (CFS) is poorly understood and no effective therapy has been developed. Recent studies suggest that a preceding viral infection causes mitochondrial dysfunction of the brain and skeletal muscle of genetically susceptible individuals. There is no specific laboratory test to identify patients with CFS. However, certain clinical manifestations are similar to those seen in mitochondrial disorders. Both patients with mitochondrial disorders and CFS manifest elevated serum lactate levels after exercise, and demonstrate elevated brain cerebrospinal fluid levels and decreased brain glutathione levels on nuclear magnetic resonance (NMR) spectroscopy. Therapy consisting of daily conditioning exercise, dietary recommendations, and nutraceutical supplements (ENT) has been show to be beneficial in treating patients with mitochondrial disorders. Similar therapy has been instituted in individual patients with CFS and has been shown to also improve their clinical conditions. A placebo-controlled trial will be undertaken in 24 CFS patients aged 25-55. Patients fulfilling the CDC criteria for CFS will participate in this 6 month study. Other medical causes for fatigue will be excluded. Half the patients will receive treatment consisting of daily conditioning exercise plus nutraceutical supplements (ENT), that has been shown to be beneficial for patients with mitochondrial dysfunction, while the other half will receive daily conditioning exercise and placebo tablets. Response to ENT will be evaluated by maximum oxygen consumption (VO2max) and circulating lactate levels during \& after treadmill exercise, a 6-minute walk test, and a fatigue questionnaire. In addition, whether ENT corrects the elevated brain cerebrospinal fluid levels and decreased brain glutathione levels will be measured. To ensure compliance to therapy patients will be monitored frequently. The objective of this study is to assess the safety and efficacy of ENT and whether ENT leads to sustained improvement of CFS patients compared to their baseline status, and compared to an exercised group of patients not receiving supplements.
Hypothesis: Many patients with underlying mitochondrial disorders have feeding problems because of poor gastrointestinal motility; feeding problems lead to growth impairment and many affected children are malnourished.
Summary. At the present, the investigators do not have the perfect anesthetic for mitochondrial patients. When possible, consideration should be given to the use of local anesthetics in small amounts. When a general anesthetic is necessary, they each carry significant risks and have been associated with poor outcomes. At present it is not possible to eliminate one group as less safe than others. What is clear is that these patients must be monitored more closely than other patients. The advent of the bispectral index (BIS) monitor may allow us to monitor their depth of anesthesia more closely and thus expose these patients only to the minimum amount of drug necessary to carry out the surgical procedure. Purpose. The investigators hypothesize that specific mitochondrial diseases, in particular those that decrease complex I function, make certain children hypersensitive to volatile anesthetics. These same patients may be at increased risk for adverse outcomes following general anesthesia. The specific aims of this application are: 1. Determine which molecular defects in mitochondrial function lead to alter sensitivity to the VA sevoflurane. 2. Establish the relative safety of sevoflurane in treatment of patients with mitochondrial disease. The investigators plan to monitor patients with mitochondrial disease using expanded measures of cardiovascular stability and measurements of brain electrical activity while slowly inducing general anesthesia. The investigators will use those measurements to limit the amount of anesthetic these patients receive in an attempt to minimize their risk. In addition, the investigators will correlate their sensitivity to the type of mitochondrial defect so that the investigators may be able to predict which patients are likely to have an increased sensitivity.
The objective of this research protocol is to continue investigation of the nature and prevalence of mitochondria disease and to aid patients and health care providers in the understanding of these complex disorders. This research study brings together many clinical sub-specialists to address the etiology of these disorders and to develop more effective approaches for their diagnoses and more reliable prognoses.
To show that oral CoQ10 is a safe and effective treatment for children with inborn errors of mitochondrial energy metabolism due to defects in specific respiratory chain (RC) complexes or mitochondrial DNA (mtDNA) mutations, and that this beneficial action is reflected in improved motor and neurobehavioral function.
