Improved Muscle Function in Duchenne Muscular Dystrophy Through L-Arginine and Metformin
study id #: NCT02516085
condition: Duchenne Muscular Dystrophy
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.
intervention: Metformin, L-Arginine
mechanism of action: Muscle cell engery regulators to prevent muscle loss
last updated: November 22, 2018
start date: January 2012
estimated completion: October 2012
phase of development: Phase 1
size / enrollment: 5
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.
- Mean change of muscle metabolism [ Time Frame: baseline to week 16 ]
mitochondrial protein expression analysis in muscular biopsies
- In vivo change of muscle metabolism [ Time Frame: baseline to week 16 ]
indirect calorimetry, Dual-Energy X-Ray Absorptiometry, quantitative thigh muscle MRI, clinical score of muscle performance
