Filter by:Wolfram syndrome is a rare genetic disorder characterized by juvenile-onset diabetes mellitus, diabetes insipidus, optic nerve atrophy, hearing loss, and neurodegeneration. The purpose of this study is to assess the safety and tolerability of dantrolene sodium in patients with Wolfram syndrome. In addition, we will assess the efficacy of dantrolene sodium on the cardinal manifestations of Wolfram syndrome, including visual acuity, remaining beta cell functions, and neurological functions. There is a screening period up to 56 days, a 6-month treatment period with an optional extension phase up to 24 months, and a 4-week safety follow-up period. Study assessments include medical & medication history, physical exams, neurological exams, eye exams, endocrine exams, vital signs, height, weight, electrocardiograms, blood and urine tests, pregnancy test if applicable, and questionnaires.
The purpose of this long term extension study is to evaluate the long-term safety of ACTIMMUNE® (interferon-γ 1b) in participants with Friedreich's Ataxia (FA).
Objectives: The objective of study was to evaluate the safety and the efficacy of EryDex (Dexamethasone sodium phosphate encapsulated in autologous erythrocytes, using the EryDex System - EDS) at two dose levels (low dose and high dose DSP/infusion), compared to placebo, on Neurological Symptoms in Patients With Ataxia Telangiectasia. Initial Double-Blind Treatment Period (0 to 6 Months) Primary Efficacy Objective: • Evaluate the effect of EryDex at two dose levels (low dose and high dose DSP/infusion), compared to placebo, on central nervous system (CNS) symptoms measured by the change in the Modified International Cooperative Ataxia Rating Scale (mICARS) from baseline to Month 6 (Visit 9) in patients with ataxia telangiectasia (A-T). Secondary Efficacy Objectives: - Evaluate the effect of EryDex, compared to placebo, on the Clinical Global Impression of Change (CGI-C) in patients with A-T from baseline to Month 6 (Visit 9). - Evaluate the effect of EryDex, compared to placebo, on measures of Clinical Global Impression of Severity (CGI-S; structured) in patients with A-T from baseline to Month 6 (Visit 9) - Evaluate the effect of EryDex, compared to placebo, on measures of Adaptive behavior measures in patients with A-T by the Vineland Adaptive Behavior Scales (VABS) from baseline to Month 6 (Visit 9). Safety Objectives: • Evaluate the safety and tolerability of two non-overlapping doses of EryDex, compared to placebo, in patients with A-T over the 12-month double-blind study duration. Extension Treatment Period (6-12 Months): Primary Objective: • Evaluate the efficacy of EryDex at two dose levels (low dose and high dose DSP/infusion) compared to placebo, in treating CNS symptoms in A-T patients during longer-term treatment (up to 12 months), as measured by the mICARS. Secondary Objectives: - Evaluate the longer-term (up to 12 months) safety and tolerability of EryDex in A-T patients. - Compare the effects of EryDex on the CGI-C and CGI-S (structured), VABS, and QoL using the EQ-5D-5L scale.
This study aims to investigate the link between the Ataxia Telangiectasia Mutated (ATM) gene and metformin response. This link has been identified from large studies of the human genome, and this study aims to confirm this link in a clinical study. The ATM gene is involved in DNA repair - if a person inherits a "faulty" copy of this gene from both their parents, they have a genetic condition called Ataxia-telangiectasia (A-T). A-T is associated with, among other things, a resistance to insulin, which causes fatty liver and diabetes. This study will recruit people who have A-T, but have not developed diabetes, and compare this group to "healthy" controls, i.e. people who do not have A-T or diabetes. The study will compare how the groups respond to two drugs used to treat diabetes (metformin and pioglitazone), with the intention that this will guide the management of diabetes in A-T. This is an, open label unblinded study recruiting 15 people with A-T and 15 age and gender matched controls. Each participant will have three study visits to the Clinical Research Centre at Ninewells hospital in Dundee - one at baseline, a second after 8 weeks of metformin and the final visit after eight weeks of pioglitazone. During each visit we will carry out a number of investigations to study the insulin resistance of A-T and how it responds to metformin and pioglitazone.
This study is an exploratory open-label clinical trial of Rosuvastatin in patients with Friedreich ataxia (FRDA). This is an outpatient trial with the goal of enrolling 10 evaluable adults with genetically confirmed FRDA who are between the ages of 18-65. Subjects will receive 10mg of oral Rosuvastatin daily for three months.
This 24-week study will test the safety and effectiveness of synthetically produced (+) Epicatechin in treating patients who have Friedreich's Ataxia, a neurological disorder.
The purpose of this study is to examine the safety and efficacy of Allopregnanolone as a possible treatment for symptoms of Fragile X-associated Tremor/Ataxia Syndrome (FXTAS).
With exposure to high altitude some individuals will develop acute mountain sickness (AMS). Current evaluation of AMS can make it difficult to rule out other possible conditions. Evaluation of ataxia, as measured by the performance of a coordinated task, can aide in the correct diagnosis of AMS. The investigators have developed novel finger-tapping tasks on a mobile device to assess both reaction time and accuracy. The proposed research will evaluate the utility of this tool in assessing human acclimatization to hypoxia.
The purpose of this phase 3 multi-center, open-label extension study is to evaluate the long-term safety of ACTIMMUNE® (interferon-γ 1b) in participants with Friedreich's 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.
