A Study to Learn More About the Effects and Long-Term Safety of BIIB141 (Omaveloxolone) in Participants With Friedreich's Ataxia Aged 2 to 15 Years Old
- Registration Number
- NCT06953583
- Lead Sponsor
- Biogen
- Brief Summary
In this study, researchers will learn more about the effects and safety of BIIB141, also known as omaveloxolone or SKYCLARYS®. This drug has been approved, or made available for doctors to prescribe, for people with Friedreich's Ataxia (FA) who are at least 16 years old. But, it is not yet available for children and teens with FA who are younger than 16 years old. The main objective of this study is to learn how BIIB141 works in the body and about its safety in children and teens who are 2 to 15 years old.
The main questions researchers want to answer in this study are:
* How does BIIB141 affect the participants' FA symptoms balance and stability?
* How many participants have medical problems during the study?
* Are there any changes in the participants' overall health during the study?
* Are there any changes in the participants' heart health?
* Are there any changes in how the participants move through puberty? Puberty is the time in someone's life when their body changes from a child to an adult.
Researchers will also learn more about:
- How the body processes BIIB141 in children and teens
This study will be done as follows:
* Participants will be screened to check if they can join the study. The screening period will be up to 28 days, after which participants will check into their study research center.
* There are 2 parts in this study. During Part 1, participants will take either BIIB141 or a placebo once a day.
* In Part 1, participants will take BIIB141 or the placebo in a study research center on Day 1, and then at in-person visits at Week 4, Week 12, Week 26, and Week 52. On all other days, they will take BIIB141 or the placebo at home. Part 1 lasts up to 52 weeks.
* During Part 2, participants from Part 1 will either continue taking BIIB141 or start it if they were taking the placebo. Part 2 will last up to 104 weeks.
* In Part 1, participants will have up to 10 visits to their study research center and a phone call at Week 2. In Part 2, participants will have visits at Weeks 4, 8,12, 26, and every 26 weeks after that until they leave the study, and a phone call at Week 2. There will be a final phone call to check on the participants' health 31 days after their last dose.
* Each participant will be in the study for up to about 3 years
- Detailed Description
The primary objective of Part 1 randomized controlled trial (RCT) is to evaluate the efficacy of omaveloxolone at Week 52 and the secondary objectives are to evaluate safety of omaveloxolone through Week 52 and the concentration of omaveloxolone after single and multiple dose administration. The primary objective of Part 2 open-label extension (OLE) trial is to evaluate the safety and tolerability of long-term omaveloxolone use and the secondary objective is to evaluate the efficacy of omaveloxolone following long-term use.

- Primary Outcome Measures
Name Time Method Part 2 OLE: Change From Baseline in Body Mass Index (BMI) Baseline (Week 52) up to Week 104 Part 2 OLE: Number of Participants With Change From Baseline in Cardiac Function Assessed by Echocardiogram (ECHO) Baseline (Week 52) up to Week 104 Part 2 OLE: Change From Baseline in Height Baseline (Week 52) up to Week 104 Part 2 OLE: Change From Baseline in Weight Baseline (Week 52) up to Week 104 Part 1 RCT: Change From Baseline in Upright Stability Score (USS) Subscale E of Modified Friedreich's Ataxia Rating Scale (mFARS) Baseline, Week 52 The mFARS is a validated and sensitive rating scale that was developed to quantitatively assess the severity of the neurologic features of FA in adults and adolescents. Scores on the mFARS range from 0 to 93, with lower scores indicating better neurological function. The subscales of the mFARS assessment and maximum score for each subscale are: bulbar function (Subscale A; 2 assessments of speech and cough; maximum score = 5), upper limb coordination (Subscale B; 5 assessments of coordination of movement and function in arms and hands with each limb scored individually; maximum score = 36), lower limb coordination (Subscale C; 2 assessments of coordination of movement and function of lower limbs with each limb scored individually; maximum score = 16), and upright stability (USS, Subscale E; 9 assessments of sitting posture, stance, tandem walk, and gait assessments; maximum score = 36).
Part 2 OLE: Number of Participants With Treatment-Emergent Adverse Event (TEAE) and Treatment-Emergent Serious Adverse Event (TESAE) From the first dose of the study drug in Part 2 up to the end of follow-up period in Part 2 (up to Week 105) Part 2 OLE: Change From Baseline in Columbia Suicide Severity Rating Scale (C-SSRS) Baseline (Week 52) up to Week 104 The C-SSRS is a low-burden measure of the spectrum of suicidal ideation and behavior that was developed to assess severity and track suicidal events through any treatment of individuals ≥ 6 years of age. The C-SSRS is a clinical interview providing a summary of both ideation and behavior that can be administered by the clinician during any evaluation or risk assessment to identify the level and type of suicidality present. The assessment includes "yes" or "no" responses for 5 questions each, related to suicidal ideation (wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with any methods, active suicidal ideation with some intent, active suicidal ideation with specific plan) and suicidal behavior (preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt, suicide). Numeric ratings are provided for severity of ideation, from 1 to 5, with 5 being the most severe.
Part 2 OLE: Percentage of Participants at Each Tanner Stage Baseline (Week 52) up to Week 104 Assessment of Tanner stages (a scale of physical development) will be performed by a medical doctor experienced with this assessment. Tanner score ranges from Stage 1 (childhood) to Stage 5 (full physical maturity). Information regarding Tanner staging will be collected at baseline for all participants and will be stopped once the participant reaches Tanner Stage 5 in all gender-appropriate scales.

The subscales of the mFARS assessment and maximum score for each subscale are: bulbar function (Subscale A; 2 assessments of speech and cough; maximum score = 5), upper limb coordination (Subscale B; 5 assessments of coordination of movement and function in arms and hands with each limb scored individually; maximum score = 36), lower limb coordination (Subscale C; 2 assessments of coordination of movement and function of lower limbs with each limb scored individually; maximum score = 16), and upright stability (USS, Subscale E; 9 assessments of sitting posture, stance, tandem walk, and gait assessments; maximum score = 36).
Part 1 RCT: Change From Baseline in Patient Global Impressions-Severity (PGI-S) Baseline, Week 52 PGI-S will be conducted for participants 7 to \< 16 years of age. These are clinically meaningful outcome measures that are participant-relevant across all age groups and disease severities for this population. PGI -S is a 1-item questionnaire where the response is recorded on a 4-point scale scored as: 1-normal, 2-mild, 3-moderate, or 4-severe.
Part 1 RCT: Change From Baseline in Clinical Global Impressions-Severity (CGI-S) Baseline, Week 52 The CGI-S will be conducted for all enrolled participants, 2 to \< 16 years of age. The CGI-S rating evaluates the severity of individual symptoms and treatment response in participants with mental disorders. The CGI-S is a 7-point scale that requires the clinician to rate the severity of the participant's illness at the time of assessment. A rating of 1 is considered normal, or with the least severe symptoms, a rating of 7 is extremely ill, or the worst symptoms.
Part 1 RCT: Change From Baseline in Friedreich's Ataxia-Activities of Daily Living (FA-ADL) Baseline, Week 52 Participants will answer the 9 questions of the FA-ADL survey in an interview style conducted by any site staff. The FA-ADL survey assesses 9 concepts: (1) speech; (2) swallowing; (3) cutting food and handling utensils; (4) dressing; (5) personal hygiene; (6) falling; (7) walking; (8) quality of sitting position; and (9) bladder function.
