Active clinical trials for "Ataxia"

This research is being done to find out if Baclofen, a medicine that is often used for the treatment of abnormal stiffness, might also be useful to treat some of the neurologic problems caused by ataxia telangiectasia (A-T). The investigators also want to find out if there are better ways to measure the problems of ataxia and abnormal eye movement for future studies of medication in ataxia telangiectasia.

Cerebellar ataxias of late onset are of undetermined etiology in many cases. A new cause of late-onset cerebellar ataxia was discovered in January 2023 corresponding to an expansion of GAA triplets in intron 1 of the FGF14 gene. However, this cerebellar ataxia is still poorly known and requires further investigations to know its clinical phenotype and its evolution in order to propose a diagnosis and a genetic counseling adapted to patients and families. The objective of our study will be to describe the clinical and genotypic phenotype of patients with GAA-FGF14

Investigators expect there will be improvement in walking speed and steadiness after taking Dalfampridine, thereby improving activities of daily living and enhancing social and occupational functions for patients with spinocerebellar ataxia.

This is a pilot/feasibility study designed to investigate the feasibility of treating children with Ataxia-Telangiectasia (A-T) and cancer with regimens nearly as intense as non-A-T patients with cancer would receive.

The purpose of this study is to determine the safety, tolerability and pharmacokinetics (PK) of single and multiple rising doses of TAK-831 in healthy participants.

This research is being done to better understand the causes of the disease Ataxia-Telangiectasia and, in the longer-term, develop new therapies for the disease using stem cells. Induced pluripotent stem cells (iPSC) are a type of cells that can be made in the laboratory from cells in your body, such as blood cells or skin cells (fibroblasts). These stem cells can then be used for research purposes. For example, stem cells can be used to investigate how the mutation in ATM causes the actual symptoms of Ataxia-Telangiectasia. In addition, the stem cells can be used to screen for drugs that could be helpful to treat the disease or to develop new laboratory techniques to correct the mutation that causes Ataxia-Telangiectasia. where the mutation that causes the disease is corrected by the investigators. The stem cells generated in this study will not be used directly for patient therapy and therefore this research does not have a direct benefit to you. However, it will help advance our understanding of the disease and develop future therapies. Patients who enroll in this study will get all of the standard therapy they would get for their tumor whether or not they participate in this study. There is no extra or different therapy given. The study involves a one-time procedure (either blood collection or skin biopsy).

This study investigated the effect of exercise using the Emil Jaques-Dalcroze's method on the postural stability of women over 65 years of age. The study model was based on a randomized controlled trial - parallel group design.

Friedreich's ataxia is a debilitating, inherited disease cause by mutations in a protein called frataxin (FXN). FXN is one of several proteins that controls the production of iron-sulfur clusters, molecules that are essential for energy production in our cells as well as repair of our genetic code embedded in DNA molecules. Friedreich's ataxia (FRDA) and deficiency of FXN results in a nerve disease affecting coordination and a condition called hypertrophic cardiomyopathy (HCM), marked by an abnormal thickening of the heart. Patients with HCM can then develop pulmonary hypertension (PH), a deadly condition of the blood vessels of the lung. While most of the research in FRDA has focused on nerves and heart muscle, alterations in blood vessels of the heart and lung may worsen disease in FRDA. But, the role of FXN in these blood vessels has never been defined. Investigators pilot data suggest that Frataxin (FXN ) deficiency can control senescence and downstream function in various types of Endothelial cells (ECs), investigators hypothesize that Friedreich's Ataxia (FRDA) patients may demonstrate endothelial cells EC abnormalities throughout the vasculature potentially before overt cardiomyopathy develops.

Ataxia telangiectasia (A-T) is a rare devastating human recessive disorder characterized by progressive cerebellar ataxia, immunodeficiency, chromosomal instability, and cancer susceptibility. The underlying mechanism and process of neurodegeneration leading to loss of cerebellar neurons and neurological function is largely unknown. Laboratory diagnostic approaches to neurodegeneration in A-T are hampered by sampling issues. It is dangerous, impractical, and not ethically to directly sample brain tissue by surgical biopsy. In contrast cerebrospinal fluid (CSF), a fluid that is in direct contact with brain tissue, is relatively easy to sample in a safe procedure (lumbar puncture). The aim of the proposal is to investigate oxidative stress, low grade inflammation and tissue break down in the brain of A-T patients by analyzing CSF. In addition the alterations in protein expression related to A-T will be quantified by liquid chromatography/mass spectrometry (LC/MS)-based proteomic analysis of CSF from healthy individuals and A-T patients to determine candidate proteins (new biomarkers) which relative expression levels could be used as surrogate marker of disease progression.

This is a Phase IV, randomized, double-blind, placebo-controlled, four-arm crossover study. The study will assess the effects of a single dose of Silenor 6 mg compared with matching placebo and a single dose of zolpidem 10 mg compared to its matching placebo at the respective T-max in normal healthy adult male volunteers. The study will be conducted in approximately 52 male subjects
