Eligibility Criteria
Inclusion Criteria:
- Boys aged between 5 and 16 years inclusive.
- Duchenne muscular dystrophy resulting from a mutation correctable by treatment with PRO044.
- Life expectancy of at least 6 months.
- No previous treatment with investigational medicinal treatment within 6 months prior to the start of the (pre)-screening for the study.
- No previous treatment with idebenone within 6 months prior to the start of the (pre)-screening for the study.

- Serum ASAT and/or ALAT concentration(s) which suggest hepatic impairment.
- Use of anticoagulants, antithrombotics or antiplatelet agents.
- Use of idebenone.
- Use of any investigational product within 6 months prior to the start of the (pre)-screening for the study.
- Subject has donated blood less than 90 days before the start of the (pre)-screening for the study.
