NCT ID: NCT02165358 Completed - Clinical trials for Becker Muscular Dystrophy

Muscle MRI in Becker Muscular Dystrophy and in Limb-girdle Muscular Dystrophy Type 2I

Start date: June 2014
Phase: N/A
Study type: Observational

The purpose of this study is to investigate the paradoxical muscle enlargement in the calves and tongue seen in patients affected by Becker muscular dystrophy and Limb-girdle muscular dystrophy type 2I. The enlarged calves' muscle quality will be assessed primarily on the basis of the muscle structure on MRI and based on a calculation of muscle strength per cross-sectional area.The findings will be compared with results from non-affected controls. Additionally we want to describe the tongue muscle appearance on T1-weighted MRI.

NCT ID: NCT02147639 Completed - Clinical trials for Becker Muscular Dystrophy

Effects of Sodium Nitrate on Blood Flow in Becker Muscular Dystrophy

Start date: October 2013
Phase: Phase 2/Phase 3
Study type: Interventional

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).

NCT ID: NCT01557400 Completed - Clinical trials for Duchenne Muscular Dystrophy

Study of Ataluren for Previously Treated Participants With Nonsense Mutation Duchenne/Becker Muscular Dystrophy (nmDBMD) in Europe, Israel, Australia, and Canada

Start date: May 20, 2012
Phase: Phase 3
Study type: Interventional

Duchenne/Becker muscular dystrophy (DBMD) 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 DBMD in approximately 10-15% 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 comprises a Phase 3, open-label study of ataluren in participants with nmDBMD who previously received ataluren at an Investigator site in a prior PTC-sponsored clinical study. A separate open-label study (PTC124-GD-016-DMD; NCT01247207) is being conducted for nmDBMD participants who previously received ataluren at an Investigator site in the United States (US).

NCT ID: NCT01519349 Completed - Clinical trials for Becker Muscular Dystrophy

Follistatin Gene Transfer to Patients With Becker Muscular Dystrophy and Sporadic Inclusion Body Myositis

Start date: January 2012
Phase: Phase 1
Study type: Interventional

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.

NCT ID: NCT01350154 Completed - Clinical trials for Becker Muscular Dystrophy

Effect of Modulating the nNOS System on Cardiac, Muscular and Cognitive Function in Becker Muscular Dystrophy Patients

Start date: November 2011
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT01126697 Completed - Clinical trials for Duchenne Muscular Dystrophy

Clinical Trial of Coenzyme Q10 and Lisinopril in Muscular Dystrophies

Start date: February 2010
Phase: Phase 2/Phase 3
Study type: Interventional

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.

NCT ID: NCT01070511 Completed - Clinical trials for Becker Muscular Dystrophy

Tadalafil in Becker Muscular Dystrophy

Start date: January 2010
Phase: Phase 4
Study type: Interventional

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.
