CoQ10 and Prednisone in Non-Ambulatory DMD

PITT0503: Clinical Trial of Coenzyme Q10 and Prednisone in Duchenne Muscular Dystrophy

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.

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
One Year Change of Left Ventricular Mean Systolic Wall Stress/Rate-corrected Velocity of Fiber Shortening Relation.
Time Frame: 12 months
Comparing change from baseline of mean systolic wall stress and rate-corrected mean velocity of circumferential shortening in the three treatment groups relative to the enhanced standard of care group and relative to each other at one year. The values are obtained via an echocardiogram read locally at each site.
12 months
One Year Change in Pulmonary Function (Forced Expiratory Volume, FEV1 and Forced Vital Capacity, FVC)
Time Frame: 12 months
Comparing change from baseline levels in pulmonary function (FEV1 and FVC) in the three treatment groups relative to the enhanced standard of care group and relative to each other at one year.
12 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Compare Side Effect Profiles of the Three Study Groups
Time Frame: 12 months
To compare side effect profiles of the three regimens to the enhanced standard of care group, to include height, weight, weight/height ratio, body mass index, cataract formation, blood glucose, blood pressure, and behavioral changes.
12 months
