45 Clinical Trials for Various Conditions
EDG-5506-203 MESA is an open-label extension study to assess the long-term effect of sevasemten (EDG-5506) on safety, biomarkers, and functional measures in adults and adolescents with Becker muscular dystrophy
A study of sevasemten (EDG-5506) in Becker muscular dystrophy (known as CANYON) and pivotal cohort (known as GRAND CANYON). The EDG-5506-201 CANYON study was expanded to include an additional 120 adult participants in a cohort called GRAND CANYON, that is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the safety and efficacy of sevasemten in adults with Becker. CANYON is fully enrolled; GRAND CANYON is currently enrolling.
This is a 24-month, observational study of 50 participants with Becker muscular dystrophy (BMD)
This Phase II pilot study is a randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, PK, PD, and exploratory clinical efficacy of vamorolone 500mg (250mg for body weight \<50 kg) daily administered orally compared to placebo over a treatment period of 24 weeks in males with BMD.

The ARCH study is an open-label, single-center, Phase 1b study of sevasemtem (EDG-5506) to assess the safety and pharmacokinetics (PK) of sevasemten in adults with Becker muscular dystrophy (BMD). Sevasemten is an investigational product intended to protect and improve function of dystrophic muscle fibers.
EDG-5506 is an investigational product intended to protect and improve function of dystrophic muscle fibers. This Phase 1 study of EDG-5506 will assess the safety, tolerability, and pharmacokinetics (PK) and of EDG-5506 in adult healthy volunteers and in adults with Becker muscular dystrophy (BMD).
This is a Phase 1, open-label, dose escalation study aimed at evaluating the safety, early efficacy and potential biomarkers of (+)-epicatechin in patients with Becker or Becker-like Muscular Dystrophy (BMD).
This 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.
This pilot study tests the hypothesis that the medication nitric oxide extract from beetroot juice improves blood flow to the skeletal muscle during exercise. The investigators will use cutting edge technology with contrast enhanced ultrasound to visualize the microvascular blood supply to the forearm. Animal studies have shown reversal of muscle damage with improved delivery of blood to the exercising muscle. This research aims to understand the mechanism of action of this medication in a way it has never been studied before. The results may help benefit individuals with muscular Dystrophy in the future.
Background: - Children with Duchenne/Becker Muscular Dystrophy (DBMD) slowly lose muscle function. They usually die at a young age. Some mothers adapt to the demands of caring for a child with this disease better than others. Studies show that a person s hope may positively affect how they cope and adapt. Researchers want to find out more about this. They want to develop ways to improve caregivers overall wellness. Objective: - To study the relationships between uncertainty, hope, and coping ability in mothers of children with DBMD. Eligibility: - Women in the United States 18 years and older. They must be biological mothers of a living child with DBMD and be able to answer a survey in English. Design: * This study is part of a larger study that examines the well-being of mothers with sons who have DBMD. * Participants will take a questionnaire. The questionnaire can be done on paper or on a computer. It will take 30 45 minutes to complete. * The questionnaire will include basic demographic questions about the participant and the child. There will also be questions about how the participant copes with the stress and uncertainty of DBMD. * For most of the questions, participants will rate their feelings on a scale. There will also be four open-ended questions.
This study is intended to build on a growing body of literature showing a blood flow abnormality in patients with Becker muscular dystrophy. The investigators' laboratory recently showed that this blood flow abnormality could be corrected by a single oral dose of the drug Tadalafil (also known as Cialis). The investigators now wish to replicate these exciting results using a common nitric oxide donor (sodium nitrate).
(-)-Epicatechin will be evaluated for the treatment of progressive muscle loss and impaired skeletal muscle function in Becker Muscular Dystrophy (BMD) patients.
This is a multi-center natural history study that will be conducted at participating centers in the Cooperative International Neuromuscular Research Group (CINRG). Following a baseline evaluation, participants will have three follow-up visits over a three-year period. The investigators will characterize the Becker muscular dystrophy phenotype, and correlate specific abnormal dystrophin proteins with the range of clinical outcomes.
The investigators are performing a gene therapy clinical trial in Becker muscular dystrophy (BMD) and sporadic inclusion body myositis (sIBM) patients. Both of these conditions have an important common feature: loss of ability to walk because of weakness of the thigh muscles. The investigators plan to do a gene therapy trial to deliver a gene to muscle called follistatin (FS344) that can build muscle size and strength. If successful, the investigators can increase the size of the thigh muscle and potentially prolong a patient's ability to walk. The gene will be carried into the muscle by a virus called adeno-associated virus (AAV). This virus occurs naturally in muscle and does not cause any human disease, setting the stage for its safe use in a clinical trial. Presently there is no treatment that can reverse Becker muscular dystrophy or sporadic inclusion body myositis. Only supportive care is currently possible. In this study, subjects with either of these diseases will have shots of the follistatin gene injected directly into thigh muscle on one (first cohort) or both legs (2nd and 3rd cohort). One hundred and eighty days following the gene delivery, the muscle will undergo biopsy to look closely at the muscle to see if the muscle fibers are bigger. Between the time of the gene transfer and the muscle biopsy, patients will be carefully monitored for any side effects of the treatment. This will include an MRI of the thigh muscle before treatment and at day 180 following treatment. Blood and urine tests, as well as physical examination will be done on the subjects during the screening visit and on days 0, 1, 2, 7, 14, 30, 60, 90, and 180 to make sure that there are no side effects from the gene injections. Sutures will be removed 2 weeks post-biopsy. Additional blood samples will be collected at 9, 12, 18, and 24 months. Patients will be seen at the end of 1st and 2nd years for a physical exam, assessment of muscle strength and appropriate blood tests.
This study, supported by Charley's Fund, Inc., is being done to determine if the drug Revatio®(also known as Sildenafil), as compared to placebo (an inactive substance that looks like the study drug, but contains no medication), improves heart function in people with Duchenne Muscular Dystrophy and Becker Muscular Dystrophy (DBMD). In people with DBMD, dystrophin is not present or lacking in heart and muscle. This is associated with abnormalities in an enzyme called "neuronal nitric oxide synthase" or nNOS, and leads to decreases in "cyclic GMP," which is necessary for proper function of those muscles. Revatio blocks an enzyme called phosphodiesterase 5 (PDE5), and helps to restore the normal amounts of cyclic GMP. The purpose of this research is to determine if Revatio is safe for people with DBMD and if it can improve heart function. Hypothesis : PDE5 inhibition, with the use of Revatio, will improve cardiac function in patients with DBMD.
Summary for Patients: This study, funded by the Muscular Dystrophy Association, is intended to build on recent findings published in the journal Nature showing beneficial effects of tadalafil (also known as Cialis) in mice with an animal version of Duchenne and Becker muscular dystrophies. Only two doses of tadalafil improved muscle blood flow, allowing the dystrophic mice to perform more exercise with less muscle injury. This new short-term clinical trial will move the testing from animals to human patients with Becker muscular dystrophy and examine the effects of acute tadalafil dosing on muscle blood flow during a bout of exercise. Patients will take two doses of tadalafil prior to exercising. Then doctors will measure whether muscles receive increased blood flow and therefore are better protected during exercise. Scientific Hypothesis: In patients with Becker muscular dystrophy (particularly those with dystrophin gene mutations between exons 41-46), loss of sarcolemmal nitric oxide synthase engenders functional muscle ischemia and thus muscle edema after an acute bout of exercise. The investigators further hypothesize that PDE5A inhibition, which boosts nitric oxide-cGMP signaling, constitutes an effective new countermeasure for these patients.
Duchenne/Becker muscular dystrophy (DMD/BMD) is a genetic disorder that develops in boys. It is caused by a mutation in the gene for dystrophin, a protein that is important for maintaining normal muscle structure and function. Loss of dystrophin causes muscle fragility that leads to weakness and loss of walking ability during childhood and teenage years. A specific type of mutation, called a nonsense (premature stop codon) mutation is the cause of DMD/BMD in approximately 10-15% of boys with the disease. Ataluren (PTC124) is an orally delivered, investigational drug that has the potential to overcome the effects of the nonsense mutation. This study is a Phase 2a trial that enrolled boys with nonsense mutation DMD/BMD who have lost independent mobility due to the disease. This study evaluated the safety and tolerability of ataluren (PTC124) and also evaluated efficacy outcomes in this participant population.

The study will also assess changes in walking, muscle function, and other important clinical and laboratory measures.
DMD/BMD is a genetic disorder that develops in boys. It is caused by a mutation in the gene for dystrophin, a protein that is important for maintaining normal muscle structure and function. Loss of dystrophin causes muscle fragility that leads to weakness and loss of walking ability during childhood and teenage years. A specific type of mutation, called a nonsense (premature stop codon) mutation is the cause of DMD/BMD in approximately 13 percent (%) of boys with the disease. Ataluren is an orally delivered, investigational drug that has the potential to overcome the effects of the nonsense mutation. This study is a Phase 2b trial that will evaluate the clinical benefit of ataluren in boys with DMD/BMD due to a nonsense mutation. The main goals of the study are to understand whether ataluren can improve walking, activity, muscle function, and strength and whether the drug can safely be given for a long period of time.
Investigators recently showed that tadalafil restores functional sympatholysis in patients with Becker muscular dystrophy (BMD). If tadalafil restores functional sympatholysis in BMD via the NO-cyclic guanosine monophosphate pathway, then functional sympatholysis should also be restored by sodium nitrite- which is an indirect nitric oxide donor.
The 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.
The purpose of this study is to understand the biochemistry of different types of Limb-Girdle Muscular Dystrophy (LGMD) and to determine appropriate outcome measures for future clinical treatment trials for LGMD. It is being conducted at two sites in the Cooperative International Neuromuscular Research Group (CINRG). It involves a one day clinical evaluation at a participating institution that will take approximately four to six hours, and will involve strength testing and muscle functional testing by a physical therapist, an evaluation by a physician, pulmonary function testing, a complete cardiac evaluation with electrocardiogram (ECG or EKG) and echocardiogram (Echo), and involve two blood draws, one before the evaluation and one after the evaluation is complete. During the visit, the participant will be asked to fill out a couple of questionnaires asking questions about quality of life and activity limitations, as well as his/her understanding of their diagnosis with regards to etiology (or cause of their muscle disorder), genetics, and inheritance of their muscle disorder.
The purpose of this phase I/II, multicenter, safety trial is to study MYO-029 in adult patients with muscular dystrophy.
This study will evaluate the antibiotic gentamicin for treating patients with muscular dystrophy caused by a specific genetic abnormality known as a nonsense mutation. In studies of mice with this type of muscular dystrophy, gentamicin treatment produced positive changes in muscle tissue. Patients with Duchenne or Becker muscular dystrophy caused by nonsense mutations by may be eligible for this 2-week study. Before starting treatment, patients will have evaluations of muscle strength and general well being. Two muscle tissue samples will be taken by needle biopsy, under local anesthetic and sedation. Because of potential risks of hearing loss and kidney toxicity associated with gentamicin, patients will also have a hearing test and blood and urine tests for kidney function before starting treatment. (Currently, gentamicin is commonly prescribed for serious infections of the lungs, heart, and digestive and urinary tracts; adverse effects of hearing loss and kidney toxicity can occur with excessively high drug doses.) Patients will be hospitalized during drug treatment. Gentamicin will be given intravenously (through a vein) once a day for 14 days. Blood samples will be collected daily to monitor drug levels and determine dosage adjustments, if necessary. Urine samples will be collected to assess kidney function. Hearing tests will be done on days 7 and 10. On the last day of the study, hearing, kidney function, and muscle strength will be tested and the results compared with pre-treatment levels. Blood and muscle samples will also be taken again for pre-treatment comparison. Hearing, blood, urine, and muscle strength tests will be repeated one month after treatment ends for comparison with previous results.
The primary objective of the Schulze study is to evaluate the function of the upper limbs of subjects diagnosed with neuromuscular disorders, with and without use of the Abilitech Assist device in the clinic and home environments. Functional outcomes will include documenting active range of motion and the ability to perform activities of daily living (ADLs) using the standardized Canadian Occupational Performance Measure (COPM) and the Role Evaluation of Activities of Life (REAL) assessments. Secondary objectives are to assess the safety record and report on adverse events (AEs) and parameters related to device usage, including device usage time and the time required to don/doff the device. Secondary objectives also include characterization of user upper limb performance based on etiology.
Current methods of measuring the response to new treatments for muscular dystrophies involve the examination of small pieces of muscle tissue called biopsies. The investigators are interested in finding less invasive methods that reduce the need for muscle biopsies. The purpose of this research is to learn about the possibility of detecting and measuring the activity and severity of muscular dystrophies by examining a urine sample and a blood sample, and some muscles in the arms and legs using tests called ultrasound and electrical impedance myography; both tests are painless and non-invasive. The information that is gathered from this study may help to evaluate, prevent, diagnose, treat, and improve the understanding of human muscle diseases.
CureDuchenne link is a data hub comprised of integrated biospecimens, clinical data, and self- and/or caregiver-reported information from participants. Anyone over 4 weeks old who has been diagnosed with DMD or BMD or who is a carrier of DMD or BMD can join. Parents or legal guardians can sign up their child(ren).
The purpose of this study is to evaluate the safety and efficacy of oral weekly glucocorticoid steroids in patients with Becker Muscular Dystrophy (BMD), an inherited disorder in which patients experience weakness of the legs and pelvis, and Limb Girdle Muscular Dystrophy (LGMD), an inherited disorder in which patients experience progressive muscular weakness predominately in their hip and shoulders. The primary objective is safety which we the investigators will measure using laboratory testing and forced vital capacity (FVC), a breathing test that measures the strength of your lungs. The secondary objective is efficacy which will be measured by a change in MRI muscle mass, improved muscle performance, and quality of life. The investigators hypothesize that patients who receive oral weekly glucocorticoid steroids will have improviements in strength and quality of life compared to their baseline. Furthermore, the investigators anticipate that oral weekly glucocorticoid steroids will not have significant adverse impact on patients.
The study objective is to identify the earliest changes in energy substrate metabolism in patients with cardiomyopathies (CMP). To achieve this objective, we plan first to test the hypothesis that patients with CMP present focal alterations in myocardial hyperpolarized \[1-13C\]pyruvate flux.
Longitudinal prospective observational study. This is a 24-month study with the possibility of extending the data time points. Initially baseline, then 12 and 24 months follow up studies will be completed.
