Current Primary Outcome Measures  ICMJE
 (submitted: July 29, 2011)
The Relative Change in Peak Systolic Radial Strain of the Left Ventricle (LV) Inferolateral Wall From Baseline (at Screening) to Week 52, Assessed by Color Doppler Myocardial Imaging (CDMI). [ Time Frame: baseline and Week 52 ]
  • Assessing the peak systolic radial strain of the left ventricle inferolateral wall is used to characterize the cardiac involvement in the DMD patients.
  • Color Doppler Myocardial Imaging technique is used to quantify regional myocardial function.
The cardiac involvement in DMD is characterized by degeneration, atrophy and fibrosis of the myocardium, leading to dilated cardiomyopathy. The process begins in the posterolateral wall of the left ventricle, with septal involvement appearing at later stages.

Descriptive Information
Brief Title  ICMJE Efficacy and Tolerability of Idebenone in Boys With Cardiac Dysfunction Associated With Duchenne Muscular Dystrophy
Official Title  ICMJE A Phase IIa Double Blind, Randomised, Placebo Controlled, Single Centre Study at the University of Leuven to Assess the Efficacy and Tolerability of Idebenone in 8 - 16 Year Old Males With Cardiac Dysfunction Associated With Duchenne Muscular Dystrophy
Brief Summary Idebenone is a synthetic analogue of coenzyme Q10 and is a powerful antioxidant and essential constituent of the process of energy production on the cellular level. It can protect mitochondria from oxidative damage and boost their impaired function. It is thought that this mechanism will slow decline in heart function that is part of the disease process of Duchenne Muscular Dystrophy (DMD). It is possible that patients may benefit in terms of muscle strength and respiratory function. This pilot trial is designed to investigate this.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Patients 8 - 16 years of age at time of enrolment
  • Male

  • Confirmed diagnosis of DMD (out of frame dystrophin gene deletion OR absent/<5% dystrophin protein on muscle biopsy; clinical picture consistent of typical DMD)
  • If on chronic glucocorticosteroids treatment (deflazacort, prednisone) for DMD (or any other disease) (i.e. concomitant medication): dosage must be stable (unchanged) 6 months prior to inclusion
  • If on chronic medication for DMD associated cardiomyopathy (β-blocker, diuretics): dosage must be stable (unchanged) 3 months prior to inclusion
  • Ability to provide reproducible repeat quantitative muscle testing (QMT) upper limb score within 15% of first assessment score (at Visit1/Day 1 versus Screening Visit

Exclusion Criteria:

  • Symptomatic cardiomyopathy or heart failure
  • Asymptomatic but severe cardiac dysfunction on baseline (Screening) evaluation: Fractional shortening (FS) < 20% and/or Ejection fraction (EF) < 40%
