Primary Outcome Measures:
  • Measures of safety and tolerability: nature and frequency of adverse events (AEs) [ Time Frame: Month 1, 3, 6, 12, 18 and 24 ] [ Designated as safety issue: Yes ]
  • Measures of safety and tolerability: haematological and biochemical laboratory parameters [ Time Frame: Month 1, 3, 6, 12, 18 and 24 ] [ Designated as safety issue: Yes ]
  • Measures of safety and tolerability: physical examinations and vital signs [ Time Frame: Month 1, 3, 6, 12, 18 and 24 ] [ Designated as safety issue: Yes ]
  • Measures of safety and tolerability: electrocardiograms (ECGs) [ Time Frame: Month 1, 3, 6, 12, 18 and 24 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Absolute change in The International Cooperative Ataxia Rating Scale (ICARS) and Friedreich Ataxia Rating Scale (FARS) scores [ Time Frame: Baseline, Month 12 and month 24 ] [ Designated as safety issue: No ]
