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). This is a group of study research centers that help provide clinical care for people with FA.
The main objective of this study is to collect safety information in participants with FA who are being prescribed BIIB141 for the first time by their own doctors.
The main question researchers want to answer in this study is:
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 must start treatment with BIIB141 within 6 months.
- 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. Most participants will visit their study research center at least once a year.
- 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.
An Observational, Multinational, Post-Marketing Registry of Omaveloxolone-Treated Patients With Friedreich's Ataxia
The primary objective of this study is to assess the long-term safety of omaveloxolone as prescribed to participants with FA in the real-world setting, including characterization of all drug-induced liver injury (DILI) and congestive heart failure (CHF) AEs. The secondary objective of this study is to capture the reasons and timing of omaveloxolone treatment interruptions, discontinuations, and drug overdose.
