Filter by:This study is done to evaluate whether treatment with the drug sildenafil (Revatio®) can improve muscular, cardiac, cerebrovascular or cognitive function in patients with Beckers muscular dystrophy when compared to placebo (inactive medication). The study is based on the recent findings of an improved cardiac function in a mouse model of muscular dystrophy (Adamo et al 2010) and the previous findings of changed cognitive function in people with Becker dystrophy. In muscular dystrophy, the cellular protein, dystrophin is affected. During normal conditions, the enzyme neuronal nitric oxide synthase (nNOS), which produce nitric oxide (NO), is attached to dystrophin. NO is important in normal vascular function in each of muscle, heart and brain by stimulating production of cyclic GMP. However, in muscular dystrophy with dystrophin deficiency, nNOS do not have the normal cellular anchor, resulting in decreased NO levels and subsequent reduced cyclic GMP production. Sildenafil inhibits degradation of cGMP thus prolonging and increasing a cGMP response. Such effects are the basis for use of sildenafil in pulmonary hypertension and erectile dysfunction. Current hypothesis: Sildenafil restores the cyclic GMP function affected in muscular dystrophy wit nNOS deficiency resulting in improved muscle, cardiac, cerebrovascular and cognitive function.
Objective of this study is to evaluate safety and tolerability of flavocoxid administered at the daily oral dose of 500 or 1000 mg/die for one year in DMD patients, alone or in association with steroids (deflazacort on alternate days) started at least one year before. The investigators will also perform a multidimensional clinical evaluation covering functional and muscle strength and quality of life (QoL)assessments.
The purpose of this study is to determine whether GSK2402968 is effective in the treatment of ambulant boys with Duchenne muscular dystrophy resulting from a mutation thought to be corrected by exon 51 skipping.
The purpose of this study is to determine whether IGF-1 therapy improves or preserves muscle function in Duchenne Muscular Dystrophy (DMD).
The aim of this multicentre, prospective, double blind, placebo controlled, randomized pilot study is to investigate safety and tolerance of Epigallocatechin-Gallate (EGCG, the major polyphenol in green tea) in patients with muscular dystrophy of the Duchenne type. In a second step the investigators want to investigate the effect of EGCG on the course of the Duchenne condition.
The purpose of this study is to describe the experiences of parents, clinician researchers, and industry professionals who were involved in phase II clinical trials of Ataluren for Duchenne muscular dystrophy. We are especially interested in learning about motivations for being involved in the clinical trial, expectations of the trial, the experience of the trial, and relationships between the parents of children involved in the trial, the clinician researchers, and PTC Therapeutics. In addition, we would like to learn more about whether and how families and advocacy organizations experiences in following the progress of the drug, encouraging the clinical trial, and supporting the phase II trials may have affected participants thoughts and feelings about the study.
The purpose of this study is to determine whether GSK2402968 given as a continuous dose and as an intermittent dose is effective and safe in the treatment of Duchenne muscular dystrophy.
The purpose of this study is investigate the pharmacokinetics, safety and tolerability of single subcutaneous administration of GSK2402968 in non-ambulant boys with Duchenne muscular dystrophy
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.
The aim of the proposed research is to compare two commonly used pediatric strength testing measures: handheld myometry (HHM) and CINRG Quantitative Measurement System (CQMS), with the goal of identifying a sensitive and valid tool for measuring muscle strength in children with DMD. The data obtained from this study will be used to make recommendations for strength measurement endpoints in prospective muscular dystrophy trials and provide more reliable and accurate recommendations in the clinic for strength assessment. This study will be performed at six participating sites in the Cooperative International Neuromuscular Research Group (CINRG).
