Participant Flow

Patients were recruited at a single centre investigational site in France.

Overall number of baseline participants differs from number of participants who started as efficacy analysis was performed on modified Intention-To-Treat (mITT) population (i.e. 21 patients). 1 patient in the placebo group did not meet the primary criteria and thus excluded from the analysis. No patient was excluded from the safety population.

The metabolism efficacy index was derived as Normalised work x creatine phosphorylation rate (sec-1). \[Normalised work was derived as Work developed during the exercise/(60 X Maximum cross section of muscle-1100)\]. Greater values of Metabolism Efficacy index indicate improvement in skeletal muscle energetics while lower values indicate the reverse. Negative values obtained using the formula indicated severe levels of muscle weakness.

The ICARS was used to measure the general clinical symptoms of Friedreich ataxia using four subscales (i.e. Posture and gait disturbances, Kinetic functions, Speech disorders, \& Oculomotor disorders). Scores for each subscale quantify the extent of ataxia in each clinically important area and subscale scores are also summed to give a total score ranging from 0 to 100, with 100 indicative of the most severely affected outcome.

Population: Due to small sample size and considering there are no specific studies in this population with EGb761; calculation with the use of a statistical hypothesis was not possible. Primary efficacy analyses performed on the mITT population and analysis of safety performed on the safety population.

The choice reaction time test was used to assess cognitive functioning. On random presentation of one of six signal lights, the patient was asked to respond as quickly and accurately as possible by removing their index finger of the dominant hand from the bottom key and pressing whichever of the top six keys was indicated by the signal. Reaction time was the time elapsed between the presentation of the stimulus and the release of the finger and movement time was defined as the time elapsed between release of the finger and pressure of the second key.
