Primary	Change From Baseline in the mFARS Score at Week 72 - Modified Intent-to-treat (mITT) Analysis Set	Baseline, Week 72	mFARS is a 93-item scale; comprised of neurologic component of FARS. For each item, responses categorize the corresponding neurological finding, with a score ranging from 0 to 3, 4, or 5 with 0 being normal and higher numbers indicative of greater impairment. Total mFARS scores for each subscale: bulbar (0 to 5), upper limb coordination (0 to 36), lower limb coordination (0 to 16), and upright stability (0 to 36). mFARS total score was a composite score of all 4 subscales, ranging from 0 (normal) to 93 (greater impairment). A lower score = better neurological function. Missing data was imputed using pattern mix model multiple imputation. Least square (LS) mean and standard error (SE) was calculated using mixed-model repeated measures (MMRM).

Secondary	Change From Baseline in Friedreich Ataxia Rating Scale Activities of Daily Living (FARS-ADL) Score at Week 72 - mITT Analysis Set	Baseline, Week 72	The ADL component of the FARS includes 9 subscales: speech, swallowing, cutting food and handling utensils, dressing, personal hygiene, falling, walking, quality of sitting position, and bladder function. Each of these subscales is rated on a 5-point scale where 0=normal to 4=severe disability/inability to carry out activity independently for a total possible score of 0 to 36, with higher scores representing greater disability/dependency. Missing data was imputed using pattern mix model multiple imputation. LS mean and SE was calculated using MMRM.

Secondary	Change From Baseline in 1-Minute Walk Test (1MWT) at Week 72 - mITT Analysis Set	Baseline, Week 72	The 1MWT is a timed performance test used to measure functional ability, walking endurance, balance, and muscle performance by measuring maximal walking speed in 1 minute. Participants were instructed to walk as quickly as possible for 1 minute without running. Maximal walking speed was measured upon completion of the walk and distance was recorded. The mean change from baseline in the distance the participant walked is reported. Missing data was imputed using pattern mix model multiple imputation. LS mean and SE was calculated using MMRM.

Secondary	Number of Falls Per 28 Days Over Every 24-Week Period - mITT Analysis Set	Week 1-24, Week 25-48, and Week 49-72	Each participant was required to maintain a fall log, which included the date and time of each fall. Falls as defined by World Health Organization as "inadvertently coming to rest on the ground, floor or other lower level, excluding intentional change in position to rest in furniture, wall or other objects," were reported. Number of falls per 28 days during a time interval was calculated as the number of falls during the period divided by the number of days during the interval, and multiplied by 28. The falls that occurred on or after the first Loss of Ambulation visit were excluded from the analysis.

Other	Change From Baseline in the Upright Stability Subscale of the mFARS at Week 72 - mITT Analysis Set	Baseline, Week 72	mFARS is a 93-item scale; comprised of neurologic component of FARS. For each item, responses categorize the corresponding neurological finding, with a score ranging from 0 to 3, 4, or 5 with 0 being normal and higher numbers indicative of greater impairment. The Upright Stability subscale of the mFARS includes following items: 1. Sitting posture (score: 0 to 4); 2a. Stance with feet apart and eyes open (score: 0 to 4); 2b. Stance with feet apart and eyes closed (score: 0 to 4); 3a. Stance with feet together and eyes open (score: 0 to 4); 3b. Stance with feet together and eyes closed (score: 0 to 4); 4. Tandem stance (score: 0 to 4); 5. Stance on dominant foot (score: 0 to 4); 6. Tandem walk (score: 0 to 3); 7. Gait (score: 0 to 5). The upright stability subscale total score ranges from 0 (normal) to 36 (greater impairment). A lower score = better neurological function. Missing data was imputed using pattern mix model multiple imputation. LS mean and SE was calculated using MMRM.

Other	Change From Baseline in the Modified Fatigue Impact Scale (MFIS) Score at Week 72 - mITT Analysis Set	Baseline, Week 72	The MFIS is a 21-item, reliable, validated instrument that has been utilized in many neurological disorders. It is a modified form of the Fatigue Impact Scale, a component of the Multiple Sclerosis Quality of Life Inventory. Each item was scored on a scale of 0 (never) to 4 (almost always). The total score was the sum of all item's score and ranged from 0 (no fatigue impact) to 84 (almost always impacted by fatigue). Higher scores indicated greater impact of fatigue on participant function.
