View clinical trials related to Cerebellar Ataxia.
Filter by:There are no clinically established treatments which have been proven to delay the disease progression in spinocerebellar ataxia (SCA) 3. Most available treatments are only for symptom alleviation, and thus the majority of patients will eventually progress to needing and wheel chair and eventually bedridden. As trehalose appear to be potentially promising treatment in SCA, the investigators aim to conduct this study using oral trehalose in our genetically confirmed SCA 3 patients.
One of the main objectives of this project is to validate potential biological, clinical and/or imaging biomarkers in SCA patients through a multimodal assessment, for future ASOs trials.
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).
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.
To evaluate the safety and tolerability of single ascending doses of CTI-1601 in participants with Friedreich's ataxia
Neurodegenerative cerebellar ataxias represent a group of disabling disorders which currently lack effective therapies. Cerebellar transcranial direct current stimulation (tDCS) is a non-invasive technique, which has been demonstrated to modulate cerebellar excitability and improve symptoms in patients with cerebellar ataxias. In this randomized, double-blind, sham-controlled study followed by an open-label phase, the investigators will evaluate whether a repetition of two-weeks' treatment with cerebellar anodal tDCS and spinal cathodal tDCS, after a three months interval, may further outlast clinical improvement in patients with neurodegenerative cerebellar ataxia and can modulate cerebello-motor connectivity, at short and long term.
The purpose of this study is to assess the Efficacy, Long Term Safety and Tolerability of RT001 in subjects with Friedreich's Ataxia
The field of clinical diagnosis of recessive cerebellar ataxias (ARCA) is particularly complex and Next Generation Sequencing (NGS) techniques have revolutionized this neuro-genetic field. The current challenge is to optimize the analysis of genetic data generated by NGS because: the processing of data remains very laborious; diagnostic yeld less than 50%; the interpretation of the variants sometimes very difficult. For this purpose of optimization, the team of the University Hospital of Strasbourg has developed a computer algorithm based on 124 clinical and para-clinical parameters (derived from the data of the literature), useful to guide the genes to be targeted in priority by genetic analysis, in the context of a suspicion of ARCA (> 60 known genes); this algorithm was validated retrospectively in 834 patients with genetically confirmed ARCA (92% Sense, 95% Spec). However, these 834 patients are often the same as those described in the literature and used for the elaboration of the algorithm. This introduces a bias in the initial evaluation of the algorithm, which therefore requires validation in clinical practice, from a cohort of patients referred for suspected ARCA (with or without a found genetic mutation). At the same time, Montpellier's genetics laboratory has developed a bioinformatic method for the search for copy number variations (CNV) that can be applied in a targeted manner to the genes predicted by the algorithm. The principal aim of this study is the validation of a semi-automated clinical algorithm for NGS molecular diagnosis of ARCA; the secondary objective is to evaluate if the application of this algorithm coupled with a targeted bioinformatic analysis can increase the diagnostic yield of the NGS analysis.
This clinical trial investigates the effects of nicotinamide riboside (vitamin B3) on the disease course of patients with ataxia telangiectasia. Patients will be treated during four consecutive months with nicotinamide riboside (25mg/kg/day), followed by a washout period of two months. Main study parameters/endpoints: Ataxia, dysarthria, quality of life, laboratory parameters.
The aim of this study is to assess the efficacy of micronised resveratrol as a treatment for FRDA, in terms of reducing the severity of ataxia symptoms at 24 weeks, through a randomised blinded, placebo controlled crossover trial.
