Primary Outcome Measures
NameTimeMethod
Main Objective: To assess the long-term safety of idebenone in DMD patients who completed the SIDEROS study.;Secondary Objective: To describe the long-term evolution of respiratory function in idebenone-treated DMD patients who completed the SIDEROS study, classified by background factors including, but not limited to age, DMD history (e.g. time of loss of ambulation, mutation type), type of steroid regimen and study treatment assignment in the SIDEROS study.<br><br>;Primary end point(s): Primary:<br>Standard safety assessments, including number of premature discontinuations of study treatment due to adverse events, incidence and severity of adverse events, actual values and changes from baseline in safety laboratory parameters, vital signs and electrocardiogram (ECG). <br><br>;Timepoint(s) of evaluation of this end point: Electrocardiogram: baseline<br>Adverse events, safety laboratory parameters, vital signs: 26 weeks , 52 weeks, 78 weeks, 82 weeks
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): Secondary:<br>Change from Baseline in Forced Vital Capacity (FVC) as percent of predicted (FVC%p), Peak Expiratory Flow (PEF) as percent of predicted (PEF%p) and Forced Expiratory Volume in 1 second (FEV1) as percent of predicted (FEV1%p). <br>;Timepoint(s) of evaluation of this end point: Forced Vital Capacity (FVC), Peak Expiratory Flow (PEF)Forced Expiratory Volume in 1 second (FEV1) : baseline, 26 weeks , 52 weeks, 78 weeks<br><br><br><br>
