A Study Investigating the Long-term Safety and Efficacy of Deferiprone in Patients With Friedreich's Ataxia
An Open-label, Single Treatment, Safety and Efficacy, Long-term Study of Deferiprone in Subjects With Friedreich's Ataxia

The primary objective of this study is to evaluate the long-term safety and tolerability of deferiprone in subjects with Friedreich's ataxia (FRDA).

The secondary objective is to evaluate the long-term efficacy of deferiprone for the treatment of FRDA.

The tertiary objectives are to evaluate the effect of deferiprone on:

  1. cardiac function,
  2. quality of life, and
  3. functional status.
This is a multi-centre, open-label, non-randomized, single treatment, safety and efficacy study. All subjects who completed the LA29-0207 study are eligible for participation. Participants will receive deferiprone oral solution at the same dose (20 or 40 mg/kg/day) that they were assigned for LA29-0207. The duration of treatment will be 52 weeks.
