Active clinical trials for "Muscular Dystrophies"

This is a 2 stage exploratory study with a 3-month observational phase on the natural course, followed by a 12-month, open-label, non-comparative, single-arm, phase II pilot study on the efficacy, safety and tolerability of a low-protein diet (LPD) in 8 adult patients with Bethlem myopathy (BM) and Ullrich congenital muscular dystrophy (UCMD). Objective of this trial is to test the effect of a normocaloric LPD to reactivate autophagy in BM/UCMD patients. The primary end point of the study will be the change in muscle biopsy of Beclin 1, a marker of autophagy, at 1 year of LPD treatment when compared to baseline. The rationale rests on our discoveries that (i) mitochondrial dysfunction mediated by inappropriate opening of the PTP plays a key role in collagen VI myopathies; (ii) defective autophagy with impaired removal of defective mitochondria amplifies the defect; and (iii) reactivation of autophagy with a low-protein diet or treatment with cyclosporine A, the mitochondrial PTP inhibitor, cured Co6a1-/- mice, hinting at a common target among all beneficial treatments - namely autophagy. Specific aims of this project are to (i) study the modifications of clinical, nutritional and laboratory parameters in a cohort of patients with BM/UCMD during a 3-month observational period before starting the LPD treatment; (ii) assess the effect of a normocaloric LPD in correcting defective autophagy in muscle of patients; (iii) test if new non-invasive biomarkers of activation of autophagy examined in the blood are mirroring the effect of LPD in the muscle biopsy; (iv) assess the clinical efficacy and safety of the LPD with an innovative combination of complementary measures of the nutritional status in patients. The anticipated output is defining and validating a therapeutic nutritional approach in autophagy upregulation for BM/UCMD.

The study will include 120 participants aged 8 and up with Duchenne, Becker, or autosomal recessive limb-girdle (specifically: LGMD 2C-2F and 2I) muscular dystrophies that have no clinical cardiac symptoms. Participants will be randomized to one of four arms: Arm 1 CoQ10 alone, Arm 2 Lisinopril alone, Arm 3 CoQ10 and Lisinopril or Arm 4 No study medication. Randomization will be stratified by ambulatory status and corticosteroid use. The primary outcome for the study is the myocardial performance index (MPI), measured by standard Doppler echocardiography. The study will last 24 months with visits at Months 0.5,1.5, 6, 12, 18 and 24. Following completion of the Clinical Trial of Coenzyme Q10 and Lisinopril, participants will be offered participation in a companion protocol: PITT1215 A Natural History Companion Study to PITT0908: Clinical Trial of Coenzyme Q10 and Lisinopril in Muscular Dystrophies. The objective of this study is to evaluate the longitudinal natural history of DMD, BMD, and LGMD2I and to evaluate the effects of Coenzyme Q10 and/or Lisinopril on prevention of cardiac dysfunction in these disorders.This will be an 18-month longitudinal natural history study designed to accompany the Clinical Trial of Coenzyme Q10 and Lisinopril in Muscular Dystrophies.

This will be a multi-center, randomized withdrawal, open-label, non-treatment concurrent control, parallel group study. Patients completing protocol BBCO-001 will be offered the opportunity to enter into this 12-month randomized withdrawal protocol.

The study is to demonstrate non-inferiority of spironolactone vs. eplerenone in preserving cardiac and pulmonary function in patients with preserved LV ejection fraction. Males with Duchenne muscular dystrophy (DMD) confirmed clinically and by mutation analysis will be enrolled. Subjects will be randomized to either eplerenone or spironolactone. Subjects will use a drug diary to record daily compliance of taking the study medication as well as any concerns they may have during the study period. Subjects will undergo cardiac magnetic resonance imaging (CMR) and pulmonary function tests (PFT) at baseline and then again at 12 months post enrollment. Subjects will also complete a quality of life questionnaire at baseline and 12 months. Degree of elbow contracture will be measured using a goniometer at baseline and 12 months.

The purpose of this study is to assess the safety and tolerability profile of ATYR1940 in the treatment of adult participants with molecularly defined genetic muscular dystrophies

The primary objective of this study is to assess the ongoing efficacy, safety, and tolerability of an additional 212 weeks of treatment with eteplirsen injection in Duchenne muscular dystrophy (DMD) subjects who have successfully completed the 28 week eteplirsen study: Study 4658-us-201. This study will also evaluate the correlation between biomarkers for DMD and the clinical status of participating DMD subjects.

This study will help to determine the effectiveness of glutamine and creatine as a possible therapy for DMD. Boys with DMD who are enrolled in this trial will be randomly chosen to receive creatine monohydrate or glutamine or an inactive placebo orally for six months. Once a month during the six-month treatment period, the study participants will have their muscle strength evaluated using manual and computerized testing methods. This study will be conducted at several CINRG Centers throughout the U.S., Belgium, Israel and Puerto Rico. This study is supported by the Muscular Dystrophy Association.

With the growing accessibility of computer-assisted technology, one option for rehabilitation programs for individuals with Duchenne muscular dystrophy (DMD) is the use of virtual reality environments to enhance motor practice. Thus, it is important to examine whether performance improvements in the virtual environment generalize to the natural environment. To examine this issue, we had 64 individuals, 32 of which were individuals with DMD and 32 were typically developing individuals. The groups practiced two coincidence timing tasks. In the more tangible button-press task, the individuals were required to 'intercept' a falling virtual object at the moment it reached the interception point by pressing a key on the computer. In the more abstract task, they were instructed to 'intercept' the virtual object by making a hand movement in a virtual environment using a webcam.

This is an interventional study on Duchenne muscular dystrophy patients who will be receiving sedation for a muscle biopsy as part of another study.

This study is to evaluate how the Wilmington Robotic Exoskeleton (WREX) is working for children who are using the WREX, or have used it in the past. The survey consists of a set of questions a) performed online and b) performed over the phone.
