Cardiac Output og Træthed ved Friedreichs Ataxi
Cardiac Output og Træthed ved Friedreichs Ataksi
This is a clinical trial examining to impact of aerobic training plus omaveloxolone in FRDA. Thirty individuals with FRDA will be recruited; 20 individuals will be on omaveloxolone treatment whereas the other ten individuals will not. Individuals will undergo baseline assessment including cardiopulmonary exercise testing (CPET), mFARS, gait speed, Timed Up and Go (TUG), Fatigue Severity Scale (FSS), Fatigue Impact Scale (FIS), and 6-minute Walk Test (6MWT). Individuals will then perform 3-months of home aerobic training. Repeat assessments will be conducted at 3- and 6-months.

Detaljeret beskrivelse
In February 2023, omaveloxolone became the first Food and Drug Administration (FDA) approved medication for Friedreich's Ataxia (FRDA). In its pivotal study, named MOXIe, researchers found that omaveloxolone significantly improved neurological function compared to placebo. The primary outcome measure was the modified Friedreich's Ataxia Rating Scale (mFARS), the gold standard for measuring ataxia symptoms in clinical trials for FRDA. However, there are several limitations with the use of mFARS:
- It does not detect subtle disease progression over short time frames. For example, in MOXIe, differences between placebo and omaveloxolone were not detected until 48 weeks.
- Some of the components of mFARS rely on clinical judgment, which can introduce variability between raters.
- The minimal clinical important difference (MCID) for mFARS has not been clearly defined.
- The scale lacks sensitivity to detect changes in individuals with minimal symptoms or advanced disease.
Given these limitations, development of additional outcome measures for clinical trials to determine the impact of drugs like omaveloxolone is desirable. In this study, investigators propose using maximal oxygen consumption (VO2max) as a future primary outcome measure for FRDA clinical trials. VO2max offers several advantages as an outcome measure:
- It is a direct physiological measure of aerobic capacity, reducing subjectivity compared to clinical scales like mFARS.
- It can detect subtle changes in aerobic function making it useful for monitoring intervention effects over time.
- It has a defined MCID, and higher VO2max is associated with better health outcomes making it a clinically meaningful endpoint.
- It is non-invasive and reproducible.
To examine the utility of VO2max as a primary outcome measure, this study will recruit 30 individuals with FRDA in this pilot study. Twenty individuals will be on omaveloxolone treatment whereas the other 10 individuals will not. Individuals will undergo baseline cardiopulmonary exercise testing (CPET) to determine VO2max. Secondary measures will include cardiac output. All participants will be given a recumbent bicycle for home use. Participants will be expected to cycle 30-minutes per session, 5x per week at 65-75% maximum heart rate (moderate intensity) for 3-months. To track training, individuals will be given a Fitbit Charge 6, and an exercise physiologist will call every two weeks to adjust training as needed. To determine benefits of training with omaveloxolone, repeat assessments will occur at 3- and 6-months.
AIM 1: Acceptability and Feasibility of Home Aerobic Exercise. Individuals with other types of ataxia have been able to train at the above levels safely. We hypothesize that there will be no serious adverse events related to aerobic training, and there will be an acceptable number of minor adverse events. The investigators further hypothesize that drop-out from the trial will be less than 25%.
AIM 2: Impact of Omaveloxolone on VO2max. Omaveloxolone works by activating and preventing the degradation of Nuclear factor-like 2 (Nrf2), which helps prevent oxidative damage within the mitochondria of individuals with FRDA. Improved mitochondrial function should significantly enhance VO2max by increasing ATP production and improving the rate of oxygen consumption. Thus, the investigators hypothesize that individuals on omaveloxolone will have a significantly larger increase in VO2max after the aerobic training when compared to individuals who are not on omaveloxolone.
AIM 3: Impact of Aerobic Training + Omaveloxolone on Fatigue. Omaveloxolone has been shown to cause a transient (12-week) increase in fatigue. Aerobic training, on the other hand, is known to improve fatigue in individuals with other hereditary ataxias. For this aim, the primary outcome measure will be the Fatigue Severity Scale (FSS) with secondary measures of Fatigue Impact Scale (FIS) and 6-minute walk test (6MWT). The investigators hypothesize improved fatigue with the incorporation of aerobic training and that individuals in the omaveloxolone group will have less fatigue than those not on omaveloxolone.
This pilot study will provide the foundation for the use of VO2max as an outcome measure in future FRDA trials. It will also examine the synergistic effect of omaveloxolone and aerobic training which may show greater improvement than either intervention alone, including improvements in fatigue.

6-Minute Walk Test
Tidsramme: 0, 3-, and 6-months
|
A functional measure of exercise capacity, we will measure the maximum distance a participant can walk in 6 minutes over a 25-meter linear course. The MCID has been determined to be between 14.0 and 30.5 meters. Fatigability will be assessed comparing the distance traveled during the last minute compared to the first minute. This difference will be divided by distance walked in the first minute and expressed as a percentage. |
0, 3-, and 6-months

|
Fatigue Impact Scale
Tidsramme: 0, 3-, 6-months
|
This scale assesses the perceived impact of fatigue on physical, cognitive, and psychosocial functioning during the participant's past four weeks. An MCID of 3.9 to 8.1 has been determined for other movement disorders such as Parkinson's Disease and Multiple Sclerosis. |
0, 3-, 6-months
|
|
Cardiac Output
Tidsramme: 0, 3-, and 6-months
|
PhysioFlow is a non-invasive device that allows you to determine cardiac output through impedence cardiography. It is FDA approved to determine cardiac output. Cardiac output will be determined both at rest and at maximal exertion during CPET testing. |
0, 3-, and 6-months
|
|
Timed Up and Go
Tidsramme: 0, 3-, and 6-months
|
To monitor balance and gait, TUG will be performed three times using the standard protocol, and the results will be averaged. Participants will be instructed to perform this test using the typical assistive device they use to walk outside if applicable. This test has been shown to be a reliable measure of balance in individuals with ataxia. |
0, 3-, and 6-months
|
|
Gait Speed
Tidsramme: 0, 3-, 6-months
|
Gait Speed will be determined by asking participants to walk as fast as possible on a 10-meter runway three times, and the times will be averaged. The MCID has been determined to be between 0.1m/s to 0.2 m/s for various patient populations. |
0, 3-, 6-months
|
|
mFARS
Tidsramme: 0, 3-, 6-months
|
mFARS is a validated measure of ataxia symptoms in individuals with FRDA. Scores range from 0-93 points, with higher scores indicating more ataxia. Research has shown the mFARS has good internal consistency, interrater and test-retest reliability. The minimal clinically important difference is not clearly defined, however. |
0, 3-, 6-months
|
|
Exercise Adherence
Tidsramme: 0, 3-, 6-months
|
We will determine the average number of days per week exercised and duration of the exercise at target heart rate. The measure for achieving levels of exercise intensity is derived from the average heart rate during an exercise session expressed as a percentage of the maximal heart rate for the individual. |
