Filter by:The aim of this study is to evaluate the efficacy and safety of C-Trelin OD Tablet 5mg(Taltirelin Hydrate) in Multicenter, randomized, double-blind, placebo-controlled clinical trial in patients with ataxia induced by spinocerebellar degeneration.
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.
This is an institutional cohort study. Patients confirmed with spinocerebellar ataxia (SCA) and taking or planning to take Nilotinib (Tasigna®) are enrolled in this study. The daily dose of Nilotinib is 150mg-300mg and the patients will be followed up at 1, 3, 6, and 12 months. Rating scale for Friedreich's ataxia I and II and Barthel index are used as general function and daily living performance index. Scale for assessment and rating of ataxia (SARA) are used as an objective measure of cerebellar function. Adverse drug reactions are evaluated based on CTCAE version 4.0.
Randomized, double-blind, placebo-controlled study on the effects of MIN-102 on Biochemical, Imaging, neurophysiological, and clinical markers in patients with Friedreich's Ataxia
The investigator proposes an open label pilot study to investigate the safety and efficacy of gamma interferon (γIFN) in patients with Friedreich's Ataxia (FRDA). yIFN, an approved drug for treatment of granulomatous disease, has been shown to promote Frataxin expression in FRDA models in vitro and in vivo as well as in pilot human studies. Safety will monitored by clinical surveillance and biohumoral periodic assessment. Efficacy will be assessed by a combination of advanced neuroimaging techniques and established clinical indicators. The investigators intend to recruit over a 6 months period 12 subject with molecularly established FRDA. The protocol builds on a recently concluded observational study which established the pattern of clinical and neuroimaging abnormalities characterizing a cohort of patients with FA. The data already acquired through such study will constitute the T-6/-12 point, and together with T0 assessment, carried out at study entrance, will provide for each patient the exact appreciation of disease actual progression over a year time. Recruited patients will receive for 6 months yIFN at a final dose of 200 ug/three times a week. Patients will be evaluated clinically after 3 and 6 months (T3 and T6) of treatment and 6 months after treatment end (T+6) and by neuroimaging at T6 and T+6. The neuroimaging protocol, based on 3 Tesla scanner, consists in functional MRI, tractography. The clinical protocol consists on specific ataxia scales administration. Regular monitoring with for eventual adverse events will be provided. Frataxin levels in the peripheral blood mononuclear cells will also be evaluated at T0, T3, T6, T+6. Furthermore, the thickness of the cardiac ventricle and retinal nerve fibre layer (RNFL) thickness with optical coherence tomography (OCT) will be performed at T0, T6, T + 6.
The purpose of this study is to examine the differences in cerebral spinal fluid (CSF) and blood of patients with spinocerebellar ataxias and healthy volunteers. The goal of this project is to identify new biomarkers that are useful for characterizing spinocerebellar ataxias and identify targets for treatment or prevention of this condition.
Traumatic Brain Injury (TBI)patients often suffer from loss of muscle strength in the hand and foot, decrease in coordination and high muscle tone (spasticity). In this study, investigators seek to compare how two different training programs can improve the coordination and symptoms of fatigue in individuals with movement deficits secondary to TBI. Using brain imaging, the study will also investigate changes in brain structure and activity associated with hand movement.
