Study Description

Brief Summary:

The purpose of the study is to assess the long-term safety and efficacy of idebenone in patients with Duchenne muscular dystrophy (DMD) who completed the SIDEROS study.

Condition or disease	Intervention/treatment	Phase
Duchenne Muscular Dystrophy	Drug: idebenone 150 mg film-coated tablets	Phase 3

Expanded Access : An investigational treatment associated with this study is temporarily not available outside the clinical trial.   More info ...

Detailed Description:

The study is an open-label, single-group, multi-center extension study in patients with DMD receiving glucocorticoid steroids who participated in the SIDEROS study and who meet all the inclusion criteria and none of the exclusion criteria for this extension study.

The study consists of 4 study visits scheduled every 6 months (Visit 1/Baseline, Visit 2/Week 26, Visit 3/ Week 52 and Visit 4/ Week 78), and a follow-up visit 4 weeks after treatment discontinuation. Visit 8/Week 78 in SIDEROS study is also SIDEROS-E Visit 1/Baseline.

   To describe the long-term evolution of respiratory function in idebenone-treated DMD patients who completed the SIDEROS study.
2. Change from Baseline in Peak Expiratory Flow (PEF) as percent of predicted (PEF%p) [ Time Frame: From baseline until visit 4 (week 78) ]
   To describe the long-term evolution of respiratory function in idebenone-treated DMD patients who completed the SIDEROS study.
3. Change from Baseline in Forced Expiratory Volume in 1 second (FEV1) as percent of predicted (FEV1%p) [ Time Frame: From baseline until visit 4 (week 78) ]
   To describe the long-term evolution of respiratory function in idebenone-treated DMD patients who completed the SIDEROS study.
