This is a natural history study prospectively investigating neuroimaging markers of disease progression in children and adults with Friedreich ataxia (FA). There will be three assessment periods (baseline, 12 and 24 months). The study will include approximately 200 individuals with FA and 100 matched controls recruited across the six international academic sites. Other assessments will include secondary clinical and cognitive markers, as well as exploratory blood markers.
Friedreich's ataxia (FA) is the most frequent recessive genetic ataxia with an estimated prevalence of 1/50 000. The first symptoms appear around the age of 10 years with a progressive course and the need for an armchair 10- 15 years after the first symptoms. More rarely the disease can present with a late onset (after the age of 25) with a picture characterized by spastic paraparesis and slower progression ("LOFA" for "Late Onset Friedreich Ataxia" or VLOFA for "Very Late Appearance of Friedreich's ataxia "). AF is caused in 96% of cases by an expansion of GAAN triplets (N> 100 repeats) located in intron 1 of the FXN gene, present on the two alleles, and, in the rest of the cases, by an associated expansion a point mutation or a deletion in trans. During molecular diagnostics, it is not uncommon to find the presence of interruptions within the GAA expansion. This results in the absence and / or the shift of peak (s) within the chromatogram. To date, only the partial correlation between the size of the expansion and the age of onset of Friedreich's ataxia has been established. In particular, very atypical forms of AF with a late onset (after the age of 25) are in particular explained by the low number of repetitions in the expansion, typically between 100 and 500 repetitions. However, the presence of an interruption could stabilize the size of the expansion and, therefore, be mainly associated with expansions of small sizes and therefore with a late onset of the disease. The objective of this study is therefore to analyse and caracterize the presence and the type of interruptions of the GAA expansions in a group of patients with FA ; this data will be correlated with the age at onset of FA.
A drug repositioning effort provided evidence supporting the possible use of Etravirine, a drug approved for the treatment of HIV infections in patients starting from 2 years of age, as a treatment for FA. We found that Etravirine is able to increase Frataxin protein both in vitro - in cells derived from FA patients - and in vivo - in the heart and skeletal muscle of Frataxin-deficient YG8 mice. Because of these findings, and since Etravirine displays a generally favorable safety profile, we plan to launch an open-label, phase 2 clinical trial aimed at assessing the safety and efficacy of Etravirine in FA patients. We aim at recruiting 30 FA patients. 15 will be treated with Etravirine for 4 months at 200 mcg/day and 15 will be treated with Etravirine for 4 months at 400 mg/day. Efficacy primary endpoint will be represented changes in peak VO2 as measured by incremental cycle ergometer exercise test. Secondary endpoints will include maximal workload, SARA score, cardiac measures, Frataxin protein levels in peripheral blood mononuclear cells and molecular analysis of Frataxin mRNA translation efficiency. Complete sets of data will be collected 4 months before the start of the treatment (T -4), at the start (T0), after 2 months (T2), at the end of the treatment (T4) and 4 months after the termination of the treatment (T8).
This research study is testing body-worn sensors to measure movement during simple tests of coordination, in order to evaluate the progression and severity of ataxia.
To test the variability of specific ribonucleic acid (RNA) and proteins as well as frataxin levels in samples of blood and buccal cells taken directly from patients with Friedreich's ataxia (FRDA) in order to confirm potential new biomarkers of disease in patients with FRDA.
Randomized, placebo-controlled trial with a 2x2 factorial design testing the effects of an NAD+ precursor (NR) and exercise on VO2max and Si in Friedreich's Ataxia (FA). The primary objective of this research is to measure the effect of combination administration (NR + exercise) on aerobic capacity (VO2max) in FA. A key secondary objective is to measure the effect of combination administration (NR + exercise) on glucose homeostasis (Si) in FA.
