Active clinical trials for "Friedreich Ataxia"

To evaluate the safety and tolerability of single ascending doses of CTI-1601 in participants with Friedreich's ataxia

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.

The primary objective of this study is to demonstrate the safety and tolerability of deferiprone in subjects with Friedreich's ataxia (FRDA). The secondary objective is to evaluate the efficacy of deferiprone for the treatment of FRDA, as assessed by a 9-Hole Peg Test (9HPT), Timed 25-Foot Walk (T25FW), Low-Contrast Letter Acuity test (LCLA), International Cooperative Ataxia Rating Scale (ICARS), and Friedreich's Ataxia Rating Scale (FARS). The tertiary objectives are to evaluate the effect of deferiprone on: cardiac function as measured by changes in Left Ventricular Shortening Fraction (LVSF), Left Ventricular Ejection Fraction (LVEF) and Left Ventricular (LV) mass using echocardiogram (ECHO), quality of life using quality-of-life surveys, and functional status using Activities of Daily Living (ADL).

This study will determine the highest amount of idebenone that can be taken without harmful side effects in children, teenagers, and adults with Friedreich's ataxia, a progressive degenerative disease that affects several body systems. Studies in France and Canada showed that patients with Friedreich's ataxia who took idebenone had a decrease in the size of their left ventricle (main pumping chamber of the heart), which is often enlarged in this disease. It is possible that idebenone may also prevent the progression of nervous system degeneration in Friedreich's ataxia. Patients 5 years of age and older with Friedreich's ataxia may be eligible for this study. Candidates are screened with a blood test and review of their medical records, including genetic studies. Participants undergo the following procedures during a 6-day hospital admission to the NIH Clinical Center: Placement of an intravenous catheter (plastic tube inserted into a vein) for collecting blood samples after drug administration Blood and urine tests Heart examination, including electrocardiogram (EKG), to assess heart function and size. Idebenone therapy: Patients take three tablets a day (at 7 AM, 1 PM and 7 PM) on days 2, 3 and 4 of hospitalization. Blood samples are collected through the IV tube at 0.5, 1, 2, 4, and 6 hours after the first dose on day 2, then at 1 hour after the first and third doses every day, and then at 1, 2, 4, 8, 12, 24, 36, and 48 hours after the last dose on day 4 to determine how the body uses and eliminates the drug. Monitoring for drug side effects: Patients have frequent checks of vital signs (blood pressure, pulse, temperature, breathing rate) and a brief physical examination to check for drug side effects from the start of drug therapy on day 2 until at least 43 hours after the last dose on day 4. Patients who experience no difficulties are discharged from the hospital after the sixth day with a 1-month supply of medication to take 3 times a day at home. They are contacted by phone every 2 weeks while taking the medication to check side effects. Blood tests are also done every 2 weeks to check for any abnormalities.

A drug repositioning effort provided evidence supporting the possible use of Etravirine, a drug approved for the treatment of HIV infections in patients starting from 2 years of age, as a treatment for FA. We found that Etravirine is able to increase Frataxin protein both in vitro - in cells derived from FA patients - and in vivo - in the heart and skeletal muscle of Frataxin-deficient YG8 mice. Because of these findings, and since Etravirine displays a generally favorable safety profile, we plan to launch an open-label, phase 2 clinical trial aimed at assessing the safety and efficacy of Etravirine in FA patients. We aim at recruiting 30 FA patients. 15 will be treated with Etravirine for 4 months at 200 mcg/day and 15 will be treated with Etravirine for 4 months at 400 mg/day. Efficacy primary endpoint will be represented changes in peak VO2 as measured by incremental cycle ergometer exercise test. Secondary endpoints will include maximal workload, SARA score, cardiac measures, Frataxin protein levels in peripheral blood mononuclear cells and molecular analysis of Frataxin mRNA translation efficiency. Complete sets of data will be collected 4 months before the start of the treatment (T -4), at the start (T0), after 2 months (T2), at the end of the treatment (T4) and 4 months after the termination of the treatment (T8).

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).

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.

Neurodegenerative cerebellar ataxias represent a group of disabling disorders for which we currently lack effective therapies. Cerebellar transcranial direct current stimulation (tDCS) is a non-invasive technique, which has been demonstrated to modulate cerebellar excitability and improve symptoms in patients with cerebellar ataxias. In this randomized, double-blind, sham-controlled study, the investigators will evaluate whether a two-weeks' treatment with cerebellar anodal tDCS and spinal cathodal tDCS can improve symptoms in patients with neurodegenerative cerebellar ataxia and can modulate cerebello-motor connectivity, at short and long term.

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.
