Outcome Measures

Primary Outcomes (1)

  • Mean change of motor function measure (MFM) D1 subscore (assessing standing and transfers)

    baseline to week 26

Secondary Outcomes (5)

  • Mean change of MFM total score, the D2, and D3 MFM subscores

    baseline to week 26

  • Mean change of six minute walking distance (6MWD)

    baseline to week 26

  • Change of quantitative muscle MRI (Magnetic Resonance Imaging) including muscle fat content (MFC) and T2 times of thigh muscles

    baseline to week 26

  • Change in the plasma/urine concentration for markers of muscle necrosis, oxidative stress, nitrosative stress, and change of microRNA (miRNA)

    baseline to week 26

  • Mean change of quantitative muscle force (QMT) of knee extension and elbow flexion using hand held dynamometry (HHD)

    baseline to week 26
