Primary Outcome Measures:
  • Mean change of motor function measure (MFM) D1 subscore after 6 and 12 weeks [ Time Frame: week 6 and week 12 ]

Secondary Outcome Measures:
  • MFM total score and six minute walking distance (6MWD) [ Time Frame: week 6 and week 12 ]
  • Change of muscle fat content (MFC) (assessed by MRI) [ Time Frame: week 6 and week 12 ]
  • Change of muscle metabolism (assessed by dual energy x-ray absorptiometry (DEXA) and indirect calorimetry) [ Time Frame: week 6 and week 12 ]
  • Change of laboratory parameters (oxidative and nitrosative stress) [ Time Frame: week 6 and week 12 ]

Enrollment: 20

Arms Assigned Interventions
Experimental: Metformin and Metformin & L-Citrulline
1500 mg/d metformin for 6 weeks, followed by 1500 mg/d metformin and 15 g/d L-citrulline for 6 further weeks
Drug: Metformin and Metformin & L-Citrulline
Experimental: L-Citrulline and Metformin & L-Citrulline
15 g/d L-citrulline for 6 weeks, followed by 1500 mg/d metformin and 15 g/d L-citrulline for 6 further weeks
Drug: L-Citrulline and Metformin & L-Citrulline

Detailed Description:

This is a single center, not-randomized open study. The study medication consists of L-citrulline and metformin administered orally; 5g citrulline and 500mg metformin tablets will be given 3 times daily.

Half of the patients will be treated with metformin during the first 6 weeks of the study. The other patients will receive initially L-citrulline for 6 weeks, before all patients will be treated with the combination therapy (metformin and L-citrulline) for another 6 week period.

The study lasts 12 weeks and includes the screening visit and 3 further visits at baseline, week 6 and week 12.
