Who cannot join

  • Iron deficiency defined as ferritin levels below the reference range for age- and sex-matched controls

About this study

Official title: A Six-month Double-blind, Randomized, Placebo-controlled Study Investigating the Safety and Tolerability of Deferiprone in Patients With 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:

  1. 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),
  2. quality of life using quality-of-life surveys, and
  3. functional status using Activities of Daily Living (ADL).
Read the detailed description

This will be a multi-centre, double-blind, randomized, placebo-controlled clinical trial. A total of 80 patients with Friedreich's ataxia will be enrolled. Eligible patients will receive deferiprone oral solution or placebo at a total daily dose of 20 mg/kg/day, 40 mg/kg/day or 60 mg/kg/day, divided into two-daily doses for 6 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing deferiprone in people with Friedreich's Ataxia, run by ApoPharma at 6 sites in 6 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Jun 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Australia, Belgium, Canada, France, Italy and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The patient's tolerance of treatment will be determined, as assessed by the occurrence of adverse events (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jun 2010.
