Brief Summary
The aim of this Phase III study was to assess the efficacy of idebenone on pulmonary function, motor function, muscle strength and quality of life in patients with DMD. Furthermore, the safety and tolerability of idebenone was assessed.

Eligibility Criteria
You may qualify if:
- Patients 10 - 18 years of age at Baseline.
- Signed and dated informed consent.
- Documented diagnosis of DMD or severe dystrophinopathy and clinical features consistent of typical DMD at diagnosis (i.e. documented delayed motor skills and muscle weakness by age 5 years). DMD should be confirmed by mutation analysis in the dystrophin gene or by substantially reduced levels of dystrophin protein (i.e. absent or \<5% of normal) on Western blot or immunostain.
- Ability to provide reliable and reproducible repeat PEF within 15% of the first assessment (i.e. Baseline vs. Screening).
- Patients assessed by the investigator as willing and able to comply with the requirements of the study, possess the required cognitive abilities and are able to swallow study medication.
You may not qualify if:
- Patients dependent on assisted ventilation at Screening and/or Baseline (defined as non-invasive nocturnal ventilation, daytime non-invasive ventilation or continuous invasive ventilation).
- Patients with documented DMD-related hypoventilation for which assisted ventilation is needed according to current standard of care guidelines (e.g. FVC\< 30%) or is required in the opinion of the Investigator.
- Patients with a percent predicted PEF \> 80% at Baseline.
- Patients unable to form a mouth seal to allow precise respiratory flow measurements and mouth pressures.
- Symptomatic heart failure (high probability of death within one year of Baseline) and/or symptomatic ventricular arrhythmias.
- Participation in the previous Phase II or Phase II Extension study (SNT-II-001 or SNT-II-001-E) for idebenone.
- Participation in any other therapeutic trial and/or intake of any investigational drug within 90 days prior to Baseline.
- Use of carnitine, creatine, glutamine, oxatomide, or any herbal medicines within 30 days prior to Baseline.
- Use of coenzyme Q10 or vitamin E (if taken at a dose of 5 times above the daily physiological requirement) within 30 days prior to Baseline.
- Any previous use of idebenone.
- Any concomitant medication with a depressive or stimulating effect on respiration or the respiratory tract.
- Planned or expected spinal fixation surgery during the study period (as judged by the investigator).
- Asthma, bronchitis/COPD, bronchiectasis, emphysema, pneumonia or the presence of any other non-DMD respiratory illness that affects PEF.
- Chronic use of beta-2 agonists or any use of other bronchodilating medication (e.g. inhaled steroids, sympathomimetics, anticholinergics).
- Please note: Chronic use if defined as a daily intake for more than 14 days.
