In this study, researchers will learn more about the safety of BIIB141, also known as omaveloxolone or SKYCLARYS®. This is a drug available for doctors to prescribe for people with Friedreich's Ataxia, also known as FA. This is known as an "observational" study, which collects health information about study participants without changing their medical care. Participants for this study will be found using a group called the Friedreich's Ataxia Global Clinical Consortium (FA GCC) UNIFIED Natural History Study (UNIFAI). The FA-GCC is a group of study research centers that helps provide clinical care for FA patients and also helps researchers learn more about how FA affects patients over a long time.
The main objective of this study is to collect safety information in participants with FA from UNIFAI. Some of the participants in this study will be prescribed BIIB141 for the first time by their own doctors. Some of the participants will have started taking BIIB141 after joining UNIFAI, but less than 12 months before joining this study.
The main questions researchers want to answer in this study are:
* How many participants had serious adverse events (SAEs)? An adverse event is considered serious when it results in death, is life-threatening, causes lasting problems, or requires hospital care. * How many participants had adverse events (AEs) related to heart failure or liver damage caused by the drug?
Researchers will also learn more about :
• Why and when participants stopped treatment, left the study, or took more of the drug than was prescribed
This study will be done as follows:
* Participants will be screened to check if they can join the study. * After joining the study, the participants who had never started BIIB141 treatment before must start it within 6 months. Otherwise, all participants will take BIIB141 throughout this study as prescribed by their own doctor. * During the study, each participant's doctor will decide how often the participant visits the study research center to check on their health. This will be based on the doctor's own clinical judgment and what is recommended by the drug's label. * Data from the participants' regular visits to their doctor will be collected at 1 month, 2 months, 3 months, 6 months, 12 months, 24 months, 36 months, 48 months, and 60 months. * Each participant will be in the study for up to 5 years.
Documented diagnosis of FA, including confirmation via genetic testing.
Participants aged 16 years and older at initiation of omaveloxolone treatment.

Previously enrolled in a clinical trial of omaveloxolone.
Participating in a blinded interventional trial at the time of enrollment in the study; participants may participate in other clinical trials after baseline data are collected.
