Active clinical trials for "Ataxia"

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

Friedreich's Ataxia (FA) is an autosomal recessive disease the mutation of which leads to a deficiency of a protein called frataxin, which is responsible for the symptoms of the disease. It is assumed that inducing an increase in the production of frataxin could reverse part of the disease's symptoms. Several treatments with drugs that raise frataxin levels have been tested, but they have either have not given the expected result or have induced intolerable side effects. The IRBLleida (Institut de Recerca Biomèdica de Lleida Fundació Dr. Pifarré) team has shown that calcitriol can increase the production of frataxin up to 2.5 to 3 times, a higher proportion than any of the drugs previously tested. For that reason, the next step in our research would be to check the effects of this drug (Calcitriol 0.25mcg/24h for a year) in patients with FA. On the other hand, calcitriol, the active form of vitamin D, is a drug with a very low rate of adverse effects that has been used for decades. Therefore, it is a drug with a very well established tolerability. The results of the present study, if positive, would lead to the organization of trials at a larger scale, and they would allow the use of an effective treatment for patients with FA.

Combining cognitive training with physical training to improve balance is a new approach for reducing the risk of falls in patient populations who are at risk for falls. People with brain pathology including cerebellar ataxia (CA) have difficulty in performing dual-tasks. Deficiency in dual-task performance relative to single-task performance referred to as dual-task cost is high in CA. Due to the high demands on cognitive resources, people with CA have higher falls rates during activities that involve dual tasking. Tai-Chi involves both cognition and physical movements making it a dual-tasking activity. However, previous study on the effects of 12-weeks of 8-form Tai-Chi did not demonstrate that it had beneficial effects in reducing falls among CA population. This null finding could potentially be due to (1) the lower levels of cognitive demands of Tai-Chi exercise, (2) the intervention not being intensive enough, or (3) the intervention may not have targeted the specific symptoms of CA. To determine if adding structured cognitive demands to conventional balance and coordination training (i.e., addressing all three possibilities for our previous null findings), the investigaotrs conducted a pilot study (n=5) to evaluate the feasibility, safety and benefits of a Cognitive-coupled Intensive Balance Training (CIBT) program. The more intensive and focused CIBT intervention reduced dual-task cost, improved balance, and reduced the number of falls in a sample of individuals with CA. Important next steps is to (1) evaluate the efficacy of the CIBT in a fully powered clinical trial, (2) understand the mechanisms underlying the benefits of CIBT training, and (3) determine the cost-benefits of this intervention. The hypothesis for the study includes (1) CIBT will improve balance and reduce falls; (2) reduction in dual-task cost of balance and cognitive performance will mediate a reduction in the number of falls in CA and (3) CIBT will be a cost-effective treatment option for improving balance and reduce falls. To test these hypotheses, a randomized controlled trial (RCT) with economic evaluation will be conducted over a period of two years to evaluate the effectiveness and cost-effectiveness of dual-task (CIBT) training compared with single-task (conventional balance: active control) training in individuals with CA.

The study is to examine the effect of functional trunk training on trunk control and upper extremity functions in patients with autosomal recessive ataxia.

The purpose of the clinical trial is to study the therapeutic efficacy and safety of Stemchymal® infusions for polyglutamine spinocerebellar ataxia treatment by a randomized, double-blind, placebo-controlled study design. Eligible subjects will receive Stemchymal® through intravenous infusion.

We propose a study on Ataxia with oculomotor apraxia type 1 (AOA1) in which Coenzyme Q10 (CoQ10) deficit has been observed. Main objectives of the study are : To monitor evolution of albumin in patients affected with AOA1 while supplemented with CoQ10 ; To measure with clinical scales and biological markers efficacy of supplementation on disease evolution. AOA1 is characterised by Hypoalbuminemia. Disease duration is negatively correlated with albumin level. This study aims to understand mechanisms of the disease and our hypothesis is that correction or stabilization of albumin level with CoQ10 supplementation could impact disease evolution. The study is planned from 1 to 2 years supplementation. The CoQ10 is classified as a food supplement and has already been tested in other neurological conditions.

The Cerebellum contains ten percent of the total volume of the brain and receives brain, spinal cord and vestibular sensory input. The organization of vestibular and somato-sensory afferent informations are also reported to be impaired in patients with cerebellum dysfunctions. Ataxia and impaired balance control are common symptoms in individuals with spinocerebellar ataxia (SCA). Previous studies have shown that patient with cerebellar damage are usually agonist and antagonist muscle coordination problem. Past studies also found the regulation of reciprocal Ia inhibition was impaired in patients with spinaocerebellar ataxia. In chronic phase, weakness might be developed due to deconditioned. All deficits mentioned above might lead to a decrease functional ability. Therefore, increasing somato-sensory and vestibular input, normalizing the modulation of recriprocal inhibition, and improve muscle strength might be able to improve the functional abilities of individuals with SCA. Recently, whole body vibration (WBV) has been trained for health groups. Studies showed that WBV training were able to improve muscle strength, balance control, and functional ability. However, there is no evidence showed that whether the whole body vibration training can affect the brain and spinal cord for the regulation of neural circuits. Whether also can affect for maximal voluntary contraction and improve central fatigue. No previous studies that whole body vibration training for SCA. Therefore, the purpose of this research was to investigate the intracortical facilitation and inhibition, reciprocal Ia inhibition, low frequency depression, maximal voluntary contraction, interpolated twitch technique to compare the different between the SCA and health subject. Also to investigate the short term and long term effect of WBV.

Spinocerebellar ataxia (SCA) is a hereditary disorder with movement incoordination. The ataxia performed low intra-cortical facilitation mainly due to the degenerative cerebellum. Noninvasive sensory stimulations such as peripheral electrical stimulation were reported to modulate the excitability of the motor excitability. Neuromuscular electrical stimulation (NMES) was proposed as a neuromodulation tool for the aberrant motor excitability on the SCA. This study aims to investigate the effect of NMES on the motor excitability in the SCA, and the differentiation on the central or peripheral motor excitability changed by the NMES.

The purpose of this study is to examine the effects of EPI-743 on visual function and neurologic function in patients with Friedreich's ataxia.
