A Study to Assess the Efficacy and Safety of Vatiquinone for the Treatment of Participants With Friedreich Ataxia

Exclusion Criteria

• •Individuals with clinical diagnosis of FA who have point mutations or deletions or other non-GAA expansion mutations
• •Previous treatment with vatiquinone
• •Allergy to vatiquinone, sesame oil, gelatin (bovine and/or porcine), titanium dioxide, or red iron oxide
• •Ejection fraction \<50%
• •Uncontrolled diabetes (glycated hemoglobin \[HbA1c\] \>7.0%) at the time of screening
• •Has current suicidal ideation based on Columbia-Suicide Severity Rating Scale (C-SSRS) within 3 months prior to screening or between screening and baseline at the baseline visit or suicidal behavior within the last year at the screening visit or between screening and baseline at the baseline visit
• •Pregnant or lactating participants or those sexually active participants who are unwilling to comply with proper birth control methods; females of childbearing potential must have a negative pregnancy test at screening and during the baseline visit
• •Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≥2 \* upper limit of normal (ULN) at time of screening
• •International normalized ratio (INR) ≥1.5 \* ULN at time of screening or clinically significant (CS) bleeding, as determined by the investigator
• •Serum creatinine ≥1.5 \* ULN at time of screening
• •Comorbidities that may confound study results (for example, fat malabsorption syndrome, other mitochondrial disorder) in the opinion of the investigator
• •Participation in any other interventional clinical trial or received any investigational drug in any other clinical trial within 60 days prior to the baseline visit. Participants may be rescreened after the exclusionary period of 60 days has passed.
• •Concomitant use of interventional coenzyme Q10 (CoQ10), vitamin E, or any approved or non-approved medication for FA within 30 days prior to the screening visit. These prohibited medications can be discontinued at the screening visit; if this is the case, the mFARS assessment must be repeated to confirm inclusion eligibility after a minimum of 30 days post-discontinuation and there must be no more than a 4-point difference in mFARS assessed from the post-discontinuation visit to the baseline visit.
• •Illicit drug use 30 days prior to screening and during the study is prohibited.
