Clinical Trial: L-citrulline and Metformin in Duchenne's Muscular Dystrophy

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: "A Double Blind Randomised Placebo Controlled Efficacy and Safety Study of L-citrulline and Metformin in Ambulant Children Aged Between 7 and 10 Years With Duchenne's Muscul

Brief Summary: The purpose of the study is to show that the intake of L-citrulline and metformin improves muscle function and delay of progression in patients with Duchenne's muscular dystrophy.

Detailed Summary: This is a single center, randomized, double-blind, placebo controlled study. The study medication consists of L-citrulline and metformin, respectively placebo given orally; 2.5 g L-citrulline or placebo will be given 3 times daily, metformin containing 250 mg or placebo will be administered 3 times daily. The duration of the study is 26 weeks and comprehends one screening and three study visits.
