Filter by:CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.
Friedreich's ataxia is characterized by progressive alterations in the function of the cerebellum accompanied by an atrophy of the spinal cord. Although the genetic defect responsible for the disease has been identified more than 15 years ago, objective markers of the pathologic process (i.e., biomarkers) that would allow measuring the effects of potential therapies are still lacking. Moreover, it is still unclear how the malfunction of the cerebellum affects the rest of the brain, and understanding the connectivity and neurochemistry of the central nervous system might yield new insights in the understanding of the disease, in addition to providing potential markers. To address these needs, the investigators aim at utilizing the capabilities of Magnetic Resonance Imaging (MRI) and Spectroscopy (MRS). Using techniques called Diffusion Imaging, resting-state functional MRI, and Proton Spectroscopy (1H MRS), the investigators propose to determine the differences in the connectivity and neurochemistry of the spinal cord and the brain between patients affected by Friedreich's ataxia and healthy controls. The investigators plan on imaging both patients and control subjects using a 3T magnet, a system that although not yet available in all medical facilities, is becoming standard in most hospitals and clinics. The first aim is to scan patients already scanned last year (12-month follow-up). The second aim is to scan patients at an early stage of the disease.
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.
The purpose of this study is to document the clinical effects of bupropion and citalopram in a single subject with Friedreich Ataxia.
The purpose of the interventional study is to determine whether Nicotinamide is effective at upregulating the Frataxin (FXN) gene in patients with Friedreich's ataxia (FRDA) where this gene is abnormally 'switched off'. The purpose of the non-interventional study is to investigate the use of novel, highly-sensitive technology to capture clinical deficit and measure subtle changes in the activities of daily living and to correlate functional changes to levels of expression of Frataxin protein and the epigenetic structure of the Frataxin gene over a 9-12 month period without nicotinamide. Healthy volunteers will be included as comparators in this part of the study.
Friedreich's ataxia (FRDA) is a rare genetic disorder characterised by severe neurological disability and cardiomyopathy. Friedreich's ataxia is the consequence of frataxin deficiency. Although several drugs have been proposed, there is no available treatment. Four trials recently demonstrated that erythropoietin can increase the intracellular levels of frataxin. The present project is aimed at testing a long term therapeutic approach using erythropoietin, which is an already available and commercialised drug. The study will test the effect of erythropoietin on exercise capacity, which is reduced in patients with FRDA. Additional objectives of the study will be the drug's safety and tolerability, and its effect on frataxin, blood vessel reactivity, heart functional indexes, and disease progression.
The purpose of this study is to determine the effect of two doses of resveratrol taken for a 12 week period, on frataxin levels in individuals with Friedreich ataxia. This study will also measure the effect of resveratrol on markers of oxidative stress, clinical measures of ataxia, and cardiac parameters.
This is a Phase IIIb Double-Blind, Randomised, Placebo-Controlled Study. The aim is to further investigate the effects of idebenone in patients with Friedreich's ataxia. The objective of the PROTI study is to establish whether patients can correctly determine which treatment assignment (placebo or idebenone) they received during the randomised phase of the trial, and identify any potential changes on symptoms or activities.
This is a Phase 2a double-blind, placebo-controlled study with two dose levels of A0001 given twice daily for 28 days. Potential subjects will be screened first to determine eligibility, after which they will be randomized to receive either a high dose of A0001, a low dose of A0001 or placebo for 28 days. Eligible subjects will return within 21 days of screening for the baseline visit and randomization to one of three potential treatments. The subjects will be required to take 3 capsules of study medication in the morning with a morning meal and 3 capsules of study medication at night with an evening meal for 28 days. Additional visits to the clinic are planned for Day 14 and Day 28, at which time a number of clinical and biochemical assessments will be done.
The primary purpose of the study is to determine whether carbamylated erythropoietin is a safe treatment for patients who suffer from Friedreich's Ataxia.
