Outcomes
Primary Outcome Measures
Change From Baseline in the Inverse Time to Complete the 9-Hole Peg Test (9-HPT-1)
The 9-HPT-1 is a measure of timed upper extremity (arm and hand) function and manual dexterity. The participant picks up pegs 1 at a time (9 in total), using 1 hand only, and places them into holes on the board as quickly as possible, in any order until all holes are filled. Then, without pausing, the participant removes the pegs 1 at a time and returns them as quickly as possible. Each participant performs this task twice with each hand separately. Results on both tests are then averaged for an overall task completion time and the inverse transform is performed. A positive change from Baseline indicates improvement. Change from Baseline in 9-HPT-1 was analyzed using mixed model for repeated measures (MMRM) analysis of covariance (ANCOVA) with Baseline 9-HPT-1 as a covariate; pooled site, visit, treatment, and ambulation status (randomization factor) as fixed factors; and treatment-by-visit and Baseline 9-HPT-1-by-visit interactions.
Secondary Outcome Measures
Change From Baseline in the Activities of Daily Living (ADL) Component Score of the Friedreich Ataxia Rating Scale (FARS)
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. A negative change from Baseline indicates improvement. Change from Baseline in FARS ADL upper limb function items were analyzed using MMRM ANCOVA with Baseline FARS ADL as a covariate; pooled site, visit, treatment, and ambulation status (randomization factor) as fixed factors; and treatment-by-visit and Baseline FARS ADL-by-visit interactions.

Change From Baseline in the Timed 25-Foot Walk (T25FW)
The participant was instructed to walk 25 feet as quickly as possible, but safely. The time was calculated from the initiation of the instruction to start and ends when the participant has reached the 25-foot mark. The task was immediately administered again by having the participant walk back the same distance. The two trials were averaged. A negative change from Baseline indicates improvement. Change from Baseline in T25FW was analyzed using MMRM ANCOVA with Baseline T25FW as a covariate; pooled site, visit, treatment, and ambulation status (randomization factor) as fixed factors; and treatment-by-visit and Baseline T25FW-by-visit interactions.
Change From Baseline in the 9-HPT and T25FW Composite Score
9-HPT and T25FW were evaluated together as a performance-based composite measure. The inverse transform of each score was computed. The inverse scores from each test were tabulated and converted to test-specific Z scores by subtracting the cohort mean from the raw score, and then dividing by the cohort standard deviation (SD) to create a Z score for the test. The composite Z scores were created by subtracting Z-score for T25FW from the Z-score for 9-HPT-1. A larger Z-score represents a better outcome. A positive change from Baseline indicates improvement. Change from Baseline in composite score was analyzed using MMRM ANCOVA with Baseline composite score as a covariate; pooled site, visit, treatment, and ambulation status (randomization factor) as fixed factors; and treatment-by-visit and Baseline composite score-by-visit interactions.

5. Study Description
Brief Summary
The purpose of this study is to evaluate the efficacy of TAK-831 versus placebo on upper extremity (arm and hands) motor function and manual dexterity. This study will also evaluate the efficacy of TAK-831 versus placebo on activities of daily living (ADL) and other secondary assessments.
Detailed Description
The drug being tested in this study is called TAK-831. TAK-831 is being tested to treat people who have Friedreich ataxia. This study will look at upper extremity (arms and hands) motor function and manual dexterity of people who take TAK-831. Efficacy evaluations also include other neurological, functional, and patient performance assessments.
The study will enroll approximately 65 participants. Participants will be randomly assigned in a 2:1:2 ratio to one of the three treatment groups-which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need):
TAK-831 High dose
TAK-831 Low dose
Placebo (dummy inactive pill) - this is a tablet that looks like the study drug but has no active ingredient
All participants will be asked to take three tablets of high dose, low dose, or placebo twice a day for 12 weeks.
This multi-center trial will be conducted in the United States. The overall time to participate in this study is approximately 13 weeks. Participants will make 5 visits to the clinic, and will be contacted by telephone for an exit interview no later than 7 days after their final visit or termination. Participants will also receive a safety follow-up phone call 7 to 17 days after receiving their last dose of TAK-831.

Title
Number of Participants by CGI-S (Upper Extremity Functional Severity) Score Categories Relative to Baseline
Description
The clinician used the CGI-S scale to assess the severity of the participant's upper extremity function on a 5-point scale where: 0=Not impaired, 1=Mildly impaired, 2=Moderately impaired, 3=Severely impaired and 4=Very severely impaired. The number of participants by CGI-S score category is reported relative to their CGI-S score at Baseline. Only those score categories reported for at least one participant at the given time-point are presented.
Time Frame
Baseline and Week 2, 7, and 12

Title
Change From Baseline in the ADL Component Score for Upper Limb Function Items of the FARS
Description
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. Items 3 to 5 are directly related to upper limb 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 12, with higher scores representing greater disability/dependency. A negative change from Baseline indicates improvement. Change from Baseline in Friedreich ataxia rating scale activities of daily living (FARS ADL) upper limb function items was analyzed using MMRM ANCOVA with Baseline FARS ADL as a covariate; pooled site, visit, treatment, and ambulation status (randomization factor) as fixed factors; and treatment-by-visit and Baseline FARS ADL-by-visit interactions.
Time Frame
Baseline and Weeks 2, 7 and 12
Title
Number of Participants With at Least a 15 Percent (%) or at Least a 20% Reduction in 9-HPT Completion Time From Baseline
Description
The 9-HPT-1 is a measure of timed upper extremity (arm and hand) function and manual dexterity. The participant picks up pegs 1 at a time (9 in total), using 1 hand only, and places them into holes on the board as quickly as possible, in any order until all holes are filled. Then, without pausing, the participant removes the pegs 1 at a time and returns them as quickly as possible. Each participant performs this task twice with each hand separately. Results on both tests are then averaged for an overall task completion time.
Time Frame
Baseline up to Week 12
