This study will help determine if CoQ10 and prednisone, alone and as a combination decrease the decline in cardiopulmonary and skeletal muscle function that occurs in the wheelchair confined phase of DMD. Participants who are enrolled in this study should not have taken any corticosteroids within the last six months. This is a 13-month, prospective, randomized study comparing a daily prednisone arm (0.75mg/kg/day), a CoQ10 arm (serum of greater than 2.5 ug/mL) and a combination arm (prednisone and CoQ10) with an enhanced standard of care arm in wheelchair confined males age 10 to 18 years with an established DMD diagnosis.
Duchenne muscular dystrophy (DMD) is the most common form of muscular dystrophy affecting 1:3500 male births worldwide. Despite an increase in our understanding of the disorder since the discovery and characterization of the causative gene and its product dystrophin in 1987, current therapeutic management remains largely supportive. Improvement in the treatment of DMD will depend upon the development of better therapies. Affected boys become symptomatic at 3 to 5 years of age with proximal leg weakness that impairs mobility, ability to get up from a squat, and precludes a normal ability to run. By 8 years of age, some affected boys begin to lose the ability to walk and resort to a wheelchair for mobility. This shift from the ambulant to non-ambulant phase occurs in all boys with a diagnosis of DMD by age 12 years. In this study, participants will be randomized into groups after being screened to determine eligibility. Participants will then be followed for a 12-month investigation period.

OBJECTIVES: I. Characterize the effect of prednisone on muscle protein metabolism in patients with Duchenne muscular dystrophy. II. Determine whether prednisone changes levels of insuli...
This study will help to determine whether a high-dose weekly course of prednisone therapy is safer than and at least as effective as daily dose therapy for people with Duchenne muscular dy...
The purpose of this study is to determine if ACE-031 is safe and well-tolerated in children with Duchenne Muscular Dystrophy (DMD) and to select the optimal doses of ACE-031 in terms of sa...
The objective of this study is to evaluate the efficacy after 24-week repeated oral doses of TAS-205 in patients with Duchenne Muscular Dystrophy (DMD) in an exploratory manner.
Data on preventive therapy in Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) affected individuals without cardiac involvement are very limited and currently lacking ...
Prolonged ambulation is considered important in children with Duchenne muscular dystrophy (DMD). However, previous studies analyzing DMD gait were sensitive to false positive outcomes, caused by uncor...
Duchenne muscular dystrophy (DMD) is an x-linked myopathy affecting one in 3,600 - 6,000 live male births. The aim of this study was to gain further insight into how parents experience caring for boys...
We report a first-in-patient study of vamorolone, a first-in-class dissociative steroidal anti-inflammatory drug, in Duchenne muscular dystrophy. This 2-week, open-label Phase IIa multiple ascending d...
Duchenne muscular dystrophy is an X-chromosome-linked genetic disorder (locus Xp21). Involvement of the cardiovascular system is characterized by fibrous degeneration/replacement of myocytes with cons...
Although prolonged ambulation is considered important in children with Duchenne muscular dystrophy (DMD), articles describing gait deviations in DMD are scarce.
A muscle protein localized in surface membranes which is the product of the Duchenne/Becker muscular dystrophy gene. Individuals with Duchenne muscular dystrophy usually lack dystrophin completely while those with Becker muscular dystrophy have dystrophin of an altered size. It shares features with other cytoskeletal proteins such as SPECTRIN and alpha-actinin but the precise function of dystrophin is not clear. One possible role might be to preserve the integrity and alignment of the plasma membrane to the myofibrils during muscle contraction and relaxation. MW 400 kDa.
A strain of mice arising from a spontaneous MUTATION (mdx) in inbred C57BL mice. This mutation is X chromosome-linked and produces viable homozygous animals that lack the muscle protein DYSTROPHIN, have high serum levels of muscle ENZYMES, and possess histological lesions similar to human MUSCULAR DYSTROPHY. The histological features, linkage, and map position of mdx make these mice a worthy animal model of DUCHENNE MUSCULAR DYSTROPHY.
An X-linked recessive muscle disease caused by an inability to synthesize DYSTROPHIN, which is involved with maintaining the integrity of the sarcolemma. Muscle fibers undergo a process that features degeneration and regeneration. Clinical manifestations include proximal weakness in the first few years of life, pseudohypertrophy, cardiomyopathy (see MYOCARDIAL DISEASES), and an increased incidence of impaired mentation. Becker muscular dystrophy is a closely related condition featuring a later onset of disease (usually adolescence) and a slowly progressive course.

MUSCULAR DYSTROPHY that occurs in VERTEBRATE animals.
A heterogenous group of inherited muscular dystrophy without the involvement of nervous system. The disease is characterized by MUSCULAR ATROPHY; MUSCLE WEAKNESS; CONTRACTURE of the elbows; ACHILLES TENDON; and posterior cervical muscles; with or without cardiac features. There are several INHERITANCE PATTERNS including X-linked (X CHROMOSOME), autosomal dominant, and autosomal recessive gene mutations.
