Duchenne Muscular Dystrophy
Conditions
Brief summary
The purpose of the study is to show that the intake of L-arginine and metformin improves muscle function and delays disease progression in patients with Duchenne's muscular dystrophy.
Detailed description
This is an investigator-initiated, open-label, single-center, proof-of-concept-study. The study medication consists of L-arginine and metformin. The duration of the study is 16 weeks and comprehends one screening and four study visits.
