L-citrulline and Metformin in Duchenne's Muscular Dystrophy
Duchenne's Muscular Dystrophy (DMD)The purpose of the study is to show that the intake of L-citrulline and metformin improves muscle function and delay of progression in patients with Duchenne's muscular dystrophy.
(-)- Epicatechin Becker Muscular Dystrophy
Becker Muscular DystrophyThis is a 48-week open-label extension of our initial proof-of-concept study (UCD0113) in patients with Becker muscular dystrophy who participated in the earlier trial. This single center study will enroll up to 10 adults who will receive the purified nutritional extract (-)-epicatechin 100mg/day orally for 8 weeks. After screening visits, participants will be enrolled in the study if they meet all inclusion criteria. They will be evaluated at screening, baseline, and weeks 4, 8, 12, 24, 16 and 48. The main criterion for success of the study will be presence of one or more biologic or strength and performance outcome measures that yield a response magnitude that allows for sufficient power in a Phase II B study with a sample size of 30 individuals.
Wearable Technology to Assess Gait Function in SMA and DMD
Spinal Muscular Atrophy Type 3Duchenne Muscular DystrophyThe purpose of this project is to devise instrumented insoles capable of accurately measuring gait at each footfall, over multiple hours in any environment. To achieve high accuracy, the investigators will develop a new learning-based calibration framework. Features will be tested in controlled lab settings 39 during a single visit in people with SMA (13), DMD (13) and healthy controls (13) and in 15 participants in real-life environments.
Tadalafil and Sildenafil for Duchenne Muscular Dystrophy
Duchenne Muscular DystrophyThis study, supported by Parent Project Muscular Dystrophy, will determine if tadalafil or sildenafil can improve muscle blood flow during exercise in boys with Duchenne muscular dystrophy.
Sodium Nitrate for Muscular Dystrophy
Becker Muscular DystrophyThe investigators' previous work in males with Becker Muscular Dystrophy shows that functional sympatholysis is restored by acute inorganic nitrate supplementation. This was translated from work using the mdx mouse model of dystrophinopathy. Recent work has shown that there is a frank improvement in grip strength when mdx mice are treated with an inorganic Nitric Oxide (NO) donor. The purpose of this study is to determine if chronic treatment with an inorganic NO donor can benefit patients with muscular dystrophy beyond blood flow regulation.
Non-invasive Imaging of Muscle Structure in Duchenne Muscular Dystrophy Using Multispectral Optoacoustic...
Duchenne Muscular DystrophyMuscular Dystrophies2 moreThis pilot study aims to assess subcellular muscle structure in patients with Duchenne X-linked progressive Duchenne muscular dystrophy (DMD) in comparison to healthy volunteers using multispectral optoacoustic tomography (MSOT). During MSOT, a transducer is placed on the skin similar to a conventional sonography and instead of sound, energy is supplied to the tissue by means of light flashes. This leads to a constant change of minimal expansions and contractions (thermoelastic expansion) of individual tissue constituents or molecules. The resulting sound waves can then be detected by the same examination unit.
Drisapersen Duchenne Muscular Dystrophy (DMD) Treatment Protocol
Muscular DystrophiesThis is a single arm, open-label continued access protocol of drisapersen for the treatment of male subjects with Duchenne muscular dystrophy (DMD) having dystrophin mutations correctable by drisapersen-induced DMD Exon 51 skipping. The purpose of this continued access protocol is to offer pre-approval access to drisapersen for the treatment of subjects with DMD who previously participated in eligible drisapersen studies. The protocol will collect safety data required to assure subject safety and periodic efficacy data on muscle function.
Flu Vaccine Study in Neuromuscular Patients 2011
Duchenne Muscular DystrophySpinal Muscular Atrophy1 moreThe purpose of the study is to compare the immune response of two different injection methods (Intramuscular V.S. Subcutaneous) of the 2011-2012 seasonal Influenza (Flu) vaccine among patients with neuromuscular conditions who have significant muscle degeneration. This research study hypothesizes that the subcutaneous route of vaccine administration, as compared to the intramuscular route, may confer at least comparable, or possibly better, immunogenicity. At least 30 individuals followed by the CCHMC Neuromuscular Comprehensive Care Center will be recruited to participate in this study lasting approximately one to two months with two clinic visits and one follow-up telephone call. Immunogenicity will be assessed by comparing hemagglutination inhibition (HI) antibody titers obtained pre- and post-vaccination.
Magnetic Resonance and Optical Imaging of Dystrophic and Damaged Muscle
Duchenne Muscular DystrophyThe purpose of this research study is to determine the potential of Optical Imaging techniques to detect muscle damage in boys with Duchenne Muscular Dystrophy and unaffected exercised muscle. Healthy subjects will undergo two different exercises in opposite forearms before any imaging techniques are performed. Boys with Duchenne Muscular Dystrophy will only undergo the imaging techniques without exercise.
Stem Cell Therapy in Duchenne Muscular Dystrophy
Duchenne Muscular DystrophyThe purpose of this study was to study the effect of stem cell therapy in patients with Duchenne Muscular Dystrophy.
